(54)LOCATION BASED AUTHENTICATION


(57) A method of enabling a user to access recorded data associated with an event, the method comprising determining the location of a user's device at a control unit, confirming the location is within a predetermined vicinity and that the user's device was at the location within a predetermined period and the control unit enabling access for the user to the data if the location of the user's device in the predetermined period is confirmed.




Description

Field



[0001] The disclosure relates to providing data associated with an event to a user, based on authentication of the user.

Background



[0002] During a live event, such as a sporting event or concert, a spectator at the venue may wish to record footage or images of the event as a memento or to share with friends. The spectator uses his or her personal camera or smartphone to make a recording of all or part of the event. This recording can then be shared online or otherwise so that it can be accessed by others. However, the quality of the video may be poor due to such things as inadequate recording equipment, distance of the spectator from the action and/or poor camerawork by the spectator.

Brief Description of the Drawings



[0003] Exemplary embodiments of the disclosure shall now be described with reference to the accompanying drawings in which:

Figure 1 shows an environment in which a live event is taking place;

Figure 2 shows a display on a user device to request access to video content;

Figure 3 shows a flow chart of a method of providing data associated with a live event to a user;

Figure 4 shows a flow chart of a method of accessing a data stream associated with a live event from a user device; and

Figure 5 shows a block diagram of one implementation of a computing device.



[0004] Throughout the description and the drawings, like reference numerals refer to like parts.

Specific Description



[0005] Figure 1 shows an environment 100 in which an arranged live event is taking place. The environment has a performance area 102 in which the live event such as a sporting, musical, political or other event is being performed. The live event is captured by installed video cameras 104a-c directed at the performance area 102 and possibly the crowd and other contributory aspects of the environment. Each video camera 104a-c has a defined location in the environment 100. In Figure 1, three video cameras are shown, although it will be appreciated that any number of video cameras could be used in order to appropriately record the live event. The cameras may be part of a system set up to record the event for later or concurrent transmission, for example as a scheduled television program. Alternatively, the cameras may be dedicated to the purpose of implementing the system disclosed herein.

[0006] The live event is observed by a crowd of spectators in the environment 100. A spectator in the crowd has a user device 106, for example a smartphone, tablet, personal computer, smartwatch, or clicker connected to the internet or other supporting communications network through a smartphone or radio frequency RF link such as Wi-Fi or Bluetooth.

[0007] The environment 100 also has a number of communication beacons 108a-e distributed about the environment. In this embodiment, the user device 106 communicates with the beacons 108a-e using Bluetooth, although other local and pico network communication schemes can be used to similar effect. Each beacon 108a-e is installed at a predefined position in the environment 100 and has its own ID. Each beacon 108a-e has a configurable broadcast range which allows it to connect with a device 106 and receive data via Bluetooth from anywhere within its broadcast range in the environment 100. The broadcast range of each beacon is adjusted so that the set of beacons provide a more or less comprehensive coverage for the spectating area of the environment. Five beacons are shown in Figure 1, although it will be appreciated that any number of beacons can be used. It will also be appreciated that increasing the number of beacons increases the granularity of the location information as described below. It is also possible to implement the disclosed method/system with a single beacon.

[0008] The system and method according to the embodiment described provides the user with the ability to request access to video or other content recorded by one or more cameras 104a-c. The system and method disclosed enable the event organiser to provide a value added service to the user as customer by providing them with access to the content recorded at the event. The content may be linked to the approximate position of the user at the event so that the user has a professionally produced record of the event from the vicinity of their own position, or the user can choose one or more camera angles. The choice is extended to selecting parts of the event, such as songs at a concert or a speech at a lecture, or time limited clips as samples of the event. Such parts can be automatically selected coincident with the time of the request during the event. For example, if a user makes a request halfway through a song, the user can automatically be provided with the video recording of the complete song starting from before the request was made.

[0009] A control unit 110 is configured to communicate with the user device 106. The control unit 110 may be located within the environment 100 or remote from it. The control unit 110 has memory storage containing a database of the locations of the video cameras 104a-c, beacon IDs of the beacons 108a-e and their locations in the environment 100. The control unit 110 also stores details of the event, for example, event type, time and duration. The control unit 110 is configured to communicate with a media processing unit MPU 112 which is located within the environment 100, but may also be remote from it. The control unit 110 and the MPU 112 may be amalgamated into a single entity. The MPU 112 receives video streams from each of the video cameras 104a-c during the event. In this embodiment, the video and/or audio data in the stream is coded according to the Moving Picture Experts Group MPEG standard. Other coding formats can be used to similar effect. The streams are stored in the memory in the MPU 112 for consumption by a user, as will be described below.

[0010] The MPU 112 communicates with the control unit 110 and the video cameras 104a-c via Wi-Fi. Other communication schemes having a bandwidth capable of supporting the streamed content can be used. For example, if the control unit 110 and/or the MPU 112 are located remotely from the environment 100, communication may be enabled over a network such as the internet or cable.

[0011] During an event, the video cameras 104a-c record the live event that is occurring in the performance area 102. The video stream of the recorded event from each of the cameras is sent to the MPU 112 and tagged to the particular event, according to location of the event, time stamps and a camera source. The video content and tag data are stored at the MPU 112. The time stamps are applied to the recorded video at various points during the event to enable retrieval of the video based on a point in the duration of the event.

[0012] A user attending the event has, for example, a smartphone as a form of the user device 106. This has an application stored on it that enables the user to gain access to and order the recorded content stored at the MPU 112. There are two levels of security for access. First, the user has to login to the application by providing an email or other identifying handle and a password or PIN that is registered for the service. The user device then has to be validated for the event the user is attending. Once validated the user has access to the recorded content for the event on request as described below. The two levels of security are optional. The login may not be needed in certain situations. However, the validation of the user actually attending the event to gain access to the content is the desirable authentication step.

[0013] The application installed in the user's smartphone 106 is illustrated by way of a screenshot in Figure 2. The user having logged in at some point before or during the event, the application is then running on the device until it is disabled. In this embodiment the application constantly or intermittently monitors for transmissions of the beacons 108 so that the current position of the device 106 relative to the beacons is always known as the closest beacon in the network at any time is captured by the device 106. In the network of beacons, capture is effected by the device opting to retrieve beacon ID information from the beacon providing the highest signal strength. This will generally equate to the closest beacon. The information on beacon capture is stored on the device for use should the user decide at some point to request recorded content associated with the live event. The location information required by the system to verify the device is supplemented by the time of the beacon ID capture. In this way the device is validated as being in the correct location at the correct time for the event. If either the location information or the time information does not correspond to the event details stored at the control unit 110, the validation is unsuccessful and access to the recordings of the event is denied. To perform the validation the location information derived from the captured beacon ID and the time of capture are sent to the control unit 110 as evidence that the user device 106 is or was in the correct vicinity at the correct time. If the validation is successful a confirmation is sent back to the device 106 which is then arranged to display on the screen a validation symbol 204. This informs the user that he/she is able to make a request for recorded content associated with the attended event.

[0014] It is preferable for the user to enable the application on the user device and perform the login either at or close to the start of the event. The device is then ready to execute a request without undue delay. However, the application could be enabled at any time during the event as required by the user. This may be preferable if the user is concerned about battery life being inadequate for the duration of the live event. Once an indication 204 appears on the screen on the device 106 the application is ready to process a request. In an alternative embodiment the user can provide verification of the presence of the device at the event by using a built-in global positioning system GPS capability. The co-ordinates for a device with this functionality can provide the necessary location information with sufficient accuracy and the beacons 108a-e are then not needed as part of the system.

[0015] By running the application for a sustained period it is likely in some events that the user will move around the venue. The location information used for validation is the latest available either by beacon capture or GPS co-ordinates.

[0016] With the login and validation procedure carried out, the control unit 110 is able to confirm from its own database of events that the device is or was present at a particular event. It then enables access to recorded content for that event and sends a confirmation back to the device 106 which responds by illuminating the indication 204. In this state a button 206 on the screen is enabled. Pressing the button causes a request to be sent from the device to the control unit for recorded content. If the control unit is in or near the environment it is possible for the request to be sent via Wi-Fi or other local transmission networks. If the control unit 110 is remote from the environment the request can be sent, for example, via a mobile telecommunications network.

[0017] In an alternative embodiment the time and location information for validation of the device 106 and the request itself are transmitted to the control unit 110 in the same or consecutive transmissions but without the need to wait for validation before making a request. The control unit 110 then determines that the device is authorised to make the request at the time the request is made and sends an acknowledgment back to the device 106. This does not require a confirmatory indication 204 but this can instead be used by way of subsequent confirmation that the request has been received by the control unit and is deemed valid.

[0018] Once a valid request is received by the control unit 110, the user is offered recorded video from at least one selected camera position 104a-c. The video cameras each offer a different perspective of the recorded event. By using the beacon ID of the beacon captured by the user device 106 or the transmitted GPS information, and the known locations of the cameras 104a-c, the control unit 110 can offer by default the recorded video from the camera closest to the user location in the environment 100 of the event. This gives the user recorded content from a similar perspective to that of his position in the environment. Other perspectives provided by other video cameras may also be selected. For example, a choice may be offered of a main feed, an on-stage feed, a user perspective and a feed from elsewhere in the crowd. In this case the device location information is not needed to fix the position of the device 106 at or near a particular camera. As illustrated in Figure 2, windows 208a-f are provided to show either thumbnails or short videos of the various camera perspectives if the user has a choice. By pressing one of the thumbnails, the request is supplemented with a specifier of the video of interest to the user. This is transmitted back to the control unit. The user then has the option of accessing the video content itself according to the selected perspective(s) at the time or later. This will be described below.

[0019] The control unit 110 can also use the time information of the user request to identify a specific part of the event, such as a song at a concert, or provide access to a defined clip of the song according to the selected camera angle. This is particularly applicable to discrete content at a live event such as a song, lecture or speech. However, the technique is equally applicable to delivering content that constitutes simply a portion of the event straddling the time of the request. Thus, the user is offered selections in the windows 208 a-f of different camera positions of the complete event, specific parts of the event straddling the request time and/or clips starting from or straddling the time of the request. The content can be made available immediately upon request or it can be reserved for later consumption.

[0020] Once the user has selected one or more of the offered recordings the completion of the request is sent back to the control unit. The control unit 110 communicates with the MPU 112 and requests that the MPU 112 extracts from the stored content the video or portion associated with the time of the request. The MPU may extract a video clip that has been requested by a user device 106 in different ways. The video clip duration may be any length within the event. It may be a particular song at a musical event during which the request was received. For a defined part of the event such as a song in a concert, the clip can be arranged to coincide with the beginning and end of the part so that what is provided to the user is the complete song. Alternatively, discrete clips with a predetermined clip duration are marked in the stored video recording. The length can be predetermined by the control unit 110 or the MPU 112. For example, the stored video recording is marked in discrete clips of 30 seconds resulting in 120 clips per hour for the event. The MPU then retrieves the most appropriate clip for each request, that is, the clip during which the user request was made. Alternatively, the user can be enabled via the application on the user device 106 to define the clip start and length.

[0021] In another form, the clips are extracted from the stored content on the basis of a configurable time window that is applied for each individual request and its timestamp. For example, for a request at time "t", a clip may begin at t-10 seconds and last until t+20 seconds. This ensures that the user receives content that has just been witnessed, as well as content following the input for context.

[0022] Alternatively, the size and/or duration of a video file may be determined dynamically based on the number of requests received within a given period. For example, a clip may have a nominal duration of 15 seconds and a timeout window of 10 seconds. That is to say, for a request of time "t", a clip may begin at t-15 seconds and last until t. If a second request is received before t+10 seconds, the duration of the video clip to be delivered is extended to include video content up to the second request. For example, if a second request is received at t+3 seconds, the final video clip will have a duration of 15 seconds + 3 seconds = 18 seconds. The clip duration is extended as further requests are received, up to a predetermined clip length, for example 30 seconds. This avoids producing large files and long video clips to be processed. In this example, the minimum duration of a clip is 15 seconds and the maximum duration of a clip is 30 seconds. In this way, a single clip can address one or more requests. The dynamic determination of video clip duration allows multiple requests received in a predetermined period to be mapped to the same video clip and the duplication of a given video moment across different video files is prevented. Furthermore, with this approach, a single request during an hour-long event would only materially generate a 15 seconds video file. This reduces storage requirements and processing time required.

[0023] In another form, the system may be configured to operate using a time limited buffer storing video content on a first-in-first-out FIFO basis. In this case, recorded content is stored in the buffer and then overwritten as newly recorded content becomes available once the buffer is full, using the FIFO approach. For example, only the previous 60 seconds of recorded content may be stored in the buffer at any given time. The buffer may be implemented at the MPU 112 or in a local memory in each respective camera 104a-c. The MPU 112 or the local memory could, of course, be configured to store a longer or shorter duration of recorded content depending on the context. The buffer provides an immediate starting point for a user request but without requiring all content for the entirety of the event to be stored. The storage is based on user demand.

[0024] In this mode, a request user to access stored content triggers the recording of further content, so that an extended duration of recorded content is provided beyond that which can be stored in the buffer. The extension of the duration of recorded content could be in line with one of the extraction methods discussed above. For example, the 60 seconds of data preceding a request are stored in the buffer and all or part of it may be copied to the memory in the MPU 112, with 20 seconds of recorded content following the request also stored in the memory in the MPU 112. In this way, the user can access content similar to that described above, although video is only streamed from the cameras 104a-c to the MPU 112 and/or stored at the MPU 112 over the duration of a live event in response to a request.

[0025] In the case that the buffer is implemented in a memory local to each respective camera 104a-c, no recorded content will even be streamed to the MPU 112 unless a user request is received.

[0026] Due to the reduction in streaming and storing requirements for video content, the system more efficiently manages video content. Such efficiency gains are particularly useful in the case that video cameras 104a-c have limited storage space and upload bandwidth, which would limit full stream recording or constant live stream uploading. When communicating with the MPU 112, the control unit 110 uses optimisation rules to cluster requests received from multiple user devices 106 for the same defined content within a predetermined time window and can consolidate them into a single request for the MPU 112. For example, if multiple users click to request the same content, such as a song, within a given window, only a single media file is requested from the stored content and generated by the MPU 112 to be accessed by the requesting user devices. By combining multiple requests from multiple users into a single file, storage and bandwidth efficiencies are realised.

[0027] Different request clustering methods may be performed. For example, one video file may be sent for all requests received over a given period. In the case that the format of the recorded video is HTTP Live Streaming HLS, a stream of video content is delivered through a series of consecutive discrete video clips which is stored at the MPU 112. One of these video clips may be sent for all requests received over a given period. Alternatively, one video clip may be sent once a given number of requests has been received. Alternatives to HLS for streaming the recorded video can be used to similar effect. The advantage of such streaming techniques as HLS is that they break the streamed video into discrete portions or clips that can be readily identified for purposes of selection.

[0028] Once a video clip is extracted from a stored video recording, the MPU 112 generates a file of the video clip and uploads it to a predefined storage platform for access. The storage platform is located remotely from the environment. Alternatively, or additionally, the storage platform may be located within the environment 100. The MPU 112 sends an access link, for example a URL, for the video clip to the control unit 110. The control unit 110 obfuscates the URL of the media clip through the use of a token based URL, where generation of a URL does not allow derivation of another valid URL. The control unit 110 then sends the obfuscated URL to the user device 106 where it is displayed for selection as a screen of the application. The user is then in possession of a link to the requested content.

[0029] The user can then access the video clip by navigating to the URL. The user can share the clip complemented with additional data, such as text comments, audio comments or images. The control unit 110 applies usage rules for the video clip, for example, a limit on the number of playbacks of the video content. In this way, the video clip may be limited to a certain number of retrievals, shares, replays and/or downloads. The limitation may be based on the identity of the device being used to access the video clip. For example, only user devices 106 authenticated as having been present at the event might be allowed to access the video clip, so that the clip can only be shared amongst attendees. Alternatively, other devices may be allowed to access the video clip, for example on a subscription or registration basis.

[0030] The limitations may be applied during the event and/or for a limited time after the event. After this time, the video clip may be arranged to no longer be available. Alternatively, the limitations may be applied for an unlimited time after the event.

[0031] A user who attended the event and had their user device validated before or during the event can be permitted access to view a convenient collection of the most popular content. Popularity can be defined in different ways. For example, the number of clip requests received during the event can be assessed at the control unit 110 to determine the most popular content. The control unit 110 then collates data on the usage of the service for an event and compiles information on audience behaviour that is of potential use to the event organisers and third parties for promotional purposes. The traffic between the user devices and the system is also useful data for deriving information for other promotional purposes, such as voting for a particular song at a concert.

[0032] Figure 3 shows a flow chart of a method 300 of enabling a user to access data associated with a live event. In this embodiment, the data is a video recording of the event. At step 302, the control unit 110 determines a location of the user device 106 from location data. The location data is derived from information based on the capture of the beacon ID of one of the beacons 108a-e by the device 106. At step 304, the control unit 110 confirms that the location derived from the location data is within a predetermined vicinity coincident with the event and that the device is at the location during the event. Alternatively, the time validation maybe within a period that starts before and ends after the scheduled time of the event or a specific window of time during the event according to the service provider's choice. At step 306, the control unit 110 enables access for the user to the recorded content if the location of the device in the period is confirmed.

[0033] In this embodiment, the user makes a request during the event. Rather than extracting a video clip based on the time of the user request, the user accesses any video content associated with the event that is available from the MPU 112. This is done either directly in response to the request or later, for example via a web browser. In this way, the control unit 110 confirms that the user was physically present at the event and enables the user to access the content, without communicating with the MPU 112 at the time. The user can then select preferred video content from any part of the event after the event has taken place, for example a particular song or the whole concert and desired camera position(s).

[0034] Figure 4 shows a flow chart of a method 400 of accessing data associated with a live event by the user device 106. At step 402, the user requests access to data using the user device 106. In this embodiment, the data is a stored video recording of the event. As above, the request includes providing location information and the time of the request. In this embodiment, the location information is the beacon ID of one of the beacons 108a-e. At step 404, the user is enabled to access the content on the user device 106 must be present within the vicinity of the event in order to be validated to access the relevant video content.

[0035] The system is adaptable to different contexts as it is applicable to different sources of media content. The system can therefore be applied to various different contexts, such as concerts, sports events, lectures, experimental laboratories, or any live event which can be recorded and shared.

[0036] Video cameras 104a-c can be professional cameras each operated by a cameraman or remotely from a control station. They, or some of them, may also be static. In other implementations, the video cameras can be replaced by any other suitable recording devices capable of providing a media feed to the MPU 112. For example, the amateur cameras based on smartphones, camcorders or action cameras could be used, or simply a microphone for audio recording only. In this way, other media content than video, such as images or audio, could be recorded and accessed by the user according to these disclosed embodiments. In the case that a smartphone, or other recording device with limited storage and bandwidth capability, is used, the buffer approach to recording content discussed above may be preferable.

[0037] Instead of video cameras at fixed locations, the video cameras 104a-c could be moveable. In this instance, the location of the video cameras is tracked and determined by the control unit 110 or the MPU 112 based on GPS data that is derived by each of the video cameras using installed GPS functionality and transmitted from there such that the control unit or the MPU 112 is able to monitor their positions. Similarly, the beacons 108a-e may also be moveable to cater, for example, for any event in which the live action moves from one place to another. The beacons are tracked using location information such as GPS. In one form, the beacons are each located on a respective video camera. The moveable beacons may each simply track an aspect of the event such that absolute location information is less important than the fact that a particular beacon is tracking a given aspect of the event.

[0038] Each beacon 108a-e can be associated with a different video feed for the same live event. For example, beacons 108a and b are associated with video camera 104a, while beacon 108c is associated with video camera 104b and beacons 108d and e are associated with video camera 104c. The control unit 110 can then identify a particular video associated with each beacon location using the mappings between the video cameras and the beacons.

[0039] Instead of Bluetooth, the user device 106 can communicate with the beacons via any wireless protocol that can interface the user device with each beacon. Instead of Wi-Fi, the user device 106 can communicate with the control unit 110 via a mobile network or Global System for Mobile GSM networks. Similarly, the position of the user device can be located through its own communications networks such as GSM, 3G, 4G or 5G instead of the beacon system referred to above or GPS.

[0040] When only links are shared between user device 106 and the control unit 110 for accessing recorded content, bandwidth efficiency is realised. A video file is only shared when accessed by the user by navigating to the associated URL. User recording of a video is no longer required as a user can access media content of the event through the control unit 110 and the recording devices, without using the processing and storage necessary to record content on the user device 106 itself.

[0041] The quality of captured content may also be improved as higher resolution recording devices may be used to capture the media content, rather than lower quality user devices having a recording function. Furthermore, as well as picture quality, angle of view and quality of direction is likely to be improved over user controlled handheld user devices.

[0042] A user does not need to invest personal time and/or have specialised knowledge to perform content capture and editing. The click of a button 206 in the application on the user device 106 can perform both the capture of the content and the editing at the same time. A user is not restricted to requesting a single recorded video of an event but can request multiple content items from multiple recording devices in sequence or simultaneously.

[0043] Disclosed herein is a method and system for supplementing a live event with the option for the attendee to access recorded content of the event. The attendee is validated as having been present at the event by location information processed through his/her user device. The attendee is able to make a request for content or a request for content options from which a selection can be made. The request can be made after access to the content has been enabled, at the same time or as a sequence as part of the same user action. The content is not accessed directly but is provided with a link to the requested content which can be retrieved at the attendee's convenience but possibly subject to usage restrictions imposed by the service provider.

[0044] A user may log into the service through an application as described above or a web page. The authentication process records the login information provided by the user, for example an email address, and also the unique device ID associated with that user device. This provides an extra layer of security to the process as only known subscribers may then use the service.

[0045] In accordance with an aspect of the disclosure there is provided a method of enabling a user to access data associated with an event to a user. The method comprises determining the location of a user's device at a control unit, confirming the location is within a predetermined vicinity and that the user's device was at the location within a predetermined period, and the control unit enabling access for the user to the data if the location of the user's device in the predetermined period is confirmed.
