Abstract (en)
[origin: WO2013074245A1] Systems and methods may be provided for masking data on public networks. At a publishing node, the system may monitor data input fields in a webpage, and intercept and encode content, such as text, images, and video input at the data input fields, prior to the content being posted online on a public service provider's website. A policy may be defined to control which users are permitted access to a key to decode the encoded content. The policy may defer to a third party policy node in determining key access. An account for a controlling entity, such as a guardian or employer, may be configured to control the encoding status of posts made by another, and decoding key access. A privacy agent may process input field content to try to detect encoding markers in the input field content, which marks content to be encoded. A third party key server may be used to store decoding keys. A URI reference to the decoding key may be used to access the decoding key by a node attempting to view the decoded version of the input field content.
