    Description

    TECHNICAL FIELD



    [0001] The present disclosure relates to the field of computer technologies, and more particularly, to a method and an apparatus for processing a surveillance video.

    BACKGROUND



    [0002] With the combination of traditional cameras and network technologies, a webcam can transmit images to the other side of the globe through a network, and a viewer at the distal end can monitor the images via a standard Web browser (such as Microsoft IE or Netscape).

    [0003] In the related art, the webcam not only may locally save a surveillance video, but also may automatically transmit the surveillance video to a network router, which is convenient for users to view the surveillance and copy backups. Although this function is practical, it brings corresponding privacy issues: any user can freely view the surveillance video stored on the router.

    [0004] Document US 2012/0257062 describes a video switch system and method of viewing surveillance videos. In Document US 2005/111660 a unique one-time key is generated to encrypt and decrypt a photographed picture.

    SUMMARY



    [0005] The invention is defined by the independent claims. Embodiments of the present disclosure provide a method and an apparatus for processing a surveillance video.

    acquiring from a user account a view request for viewing a surveillance video file, the view request including authorization information of the user account;

    performing an identity authentication on the user account according to the authorization information; and

    allowing the user account to view the surveillance video file when the identity authentication is passed.



    [0007] In the present embodiment, an identity authentication is performed on the user who accesses the surveillance video file, and only the user whose identity authentication is passed is allowed to view the surveillance video, such that the surveillance video cannot be viewed freely, thereby to prevent leakage of user privacy information, so as to effectively protect the user's privacy.

    [0008] Optionally, the method further includes:
    performing a privacy protection operation on the surveillance video file uploaded from a camera device.

    [0009] In the optional solution, a privacy protection operation is performed on the surveillance video file, such that the surveillance video cannot be viewed freely, thereby to prevent leakage of user privacy information, so as to effectively protect the user's privacy.

    [0010] Optionally, the step of performing a privacy protection operation on the surveillance video file uploaded from a camera device includes at least one of the following operations:

    setting properties of the surveillance video file to be hidden; and

    encrypting the surveillance video file.



    [0011] In the optional solution, by either hiding the surveillance video file or encrypting the surveillance video file, or by combination thereof, the surveillance video file is protected, such that the surveillance video cannot be viewed freely, thereby to prevent leakage of user privacy information, so as to effectively protect the user's privacy.

    [0012] Optionally, the step of encrypting the surveillance video file includes:

    acquiring a file key used for encrypting the surveillance video file; and

    distributing the file key to a preset user account.

    [0015] In the optional solution, the owner who owns the camera device may preset user accounts that have authorization to access the surveillance video file, and the terminal distributes the file key to such users, such that these users may view the surveillance video file. As such, only the users who have access authorization are allowed to view the surveillance video file stored on the terminal, so as to effectively protect the user's privacy.

    [0016] Optionally, the method further includes:

    acquiring a user private key of a preset user account;

    generating a user public key of the preset user account according to the file key and the user private key of the preset user account; and

    sending the user public key to a corresponding preset user account, such that the preset user account generates a file key of the surveillance video file according to the user public key and the user private key.



    [0017] In the optional solution, based on the RSA public-key cryptosystem, the key for encrypting files can be avoided from being published; meanwhile, although the key for encrypting files is constant, private keys of respective preset user accounts may be different from each other, so that public keys generated by the terminal for respective user accounts are different from each other; thus, even if public keys of respective user accounts are published, the key for encrypting files cannot be obtained by other people, thereby to further enhance the safety of the key for encrypting files, enhance the safety of surveillance video files, and more effectively protect the user's privacy.

    [0018] Optionally, when properties of the surveillance video file are set to be hidden, the step of allowing the user account to view the surveillance video file when the identity authentication is passed includes:

    [0020] Optionally, when the surveillance video file is encrypted, the step of allowing the user account to view the surveillance video file when the identity authentication is passed includes:

    acquiring the file key inputted from the user account when the identity authentication is passed;

    decrypting the surveillance video file based on the file key; and

    putting the decrypted surveillance video file on display.



    [0021] In the optional solution, when the user's identity authentication is passed, the terminal prompts the user to input the file key, whereby to decrypt the surveillance video file and display it to the user, so as to achieve protection on the surveillance video file, such that the surveillance video cannot be viewed freely, thereby to prevent leakage of user privacy information, and to effectively protect the user's privacy.

    [0022] Optionally, the file key is a user password of an account of the owner who owns the camera device that captures the surveillance video file, and the authorization information includes a user name and a user password of the user account; and
    the step of allowing the user account to view the surveillance video file when the identity authentication is passed includes:

    when it is determined, based on the authorization information, that the user account is the account of the owner who owns the camera device that captures the surveillance video file, decrypting the surveillance video file by using the user password of the account of the owner who owns the camera device that captures the surveillance video file; and

    putting the decrypted surveillance video file on display.



    [0023] In the optional solution, when the owner who owns the camera device encrypts the surveillance video file by using the user password of his/her own account, if it is determined by identity authentication that the accessing person is the owner who owns the camera device him/herself, the surveillance video file is directly decrypted for the user, such that the owner who owns the camera device may conveniently and quickly access the surveillance video file.

The implementations set forth in the following description of exemplary embodiments do not represent all implementations consistent with the present disclosure. Instead, they are merely examples of apparatuses and methods consistent with aspects related to the present disclosure as recited in the appended claims.

    [0038] A surveillance video file captured by a camera device (such as a surveillance camera) is uploaded to a terminal device (e.g., a computer or a router). The present disclosure mainly performs a privacy protection on the surveillance video file uploaded to the terminal device.

    [0039] FIG. 1 is a flowchart illustrating a method for processing a surveillance video according to an exemplary embodiment. As shown in FIG. 1, a camera device uploads a surveillance video file to a terminal. The method for processing the surveillance video is performed by the terminal, and includes the following steps.

    In step S11, a view request for viewing a surveillance video file is acquired from a user account, the view request including authorization information of the user account;

    In step S12, an identity authentication is performed on the user account according to the authorization information;

    In step S13, the user account is allowed to view the surveillance video file when the identity authentication is passed.



    [0040] In the present embodiment, an identity authentication is performed on the user who accesses the surveillance video file, and only the user whose identity authentication is passed is allowed to view the surveillance video, such that the surveillance video cannot be viewed freely, thereby to prevent leakage of user privacy information, so as to effectively protect the user's privacy.

    [0041] FIG. 2 is a flowchart illustrating a method for processing a surveillance video according to another exemplary embodiment. As shown in FIG. 2, optionally, the method further includes the following step.

    [0042] In step S10, a privacy protection operation is performed on the surveillance video file uploaded from the camera device.

    [0043] In the optional solution, a privacy protection operation is performed on the surveillance video file, such that the surveillance video cannot be viewed freely, thereby to prevent leakage of user privacy information, so as to effectively protect the user's privacy.

    [0044] Optionally, step S10 includes at least one of the following operations:

    setting properties of the surveillance video file to be hidden;

    encrypting the surveillance video file.



    [0045] In the optional solution, by either hiding the surveillance video file or encrypting the surveillance video file, or by combination thereof, the surveillance video file is protected, such that the surveillance video cannot be viewed freely, thereby to prevent leakage of user privacy information, so as to effectively protect the user's privacy.

    [0046] FIG. 3 is a flowchart illustrating a method for processing a surveillance video according to another exemplary embodiment. As shown in FIG. 3, optionally, the step of encrypting the surveillance video file includes the following steps.
