Patent ID: 8752197

Claim:
A system for protecting privacy of information conveyed by one or more images in a common image stream, the system comprising: a selector for selecting descriptive data from the one or more images in a video frame in the common image stream, wherein the descriptive data includes a plurality of different objects displayed within the video frame; an encryption element configured to selectively encrypt each of the plurality of different objects displayed within the video frame in the common image stream with one or more different, respective encryption keys, wherein each of the plurality of different objects is encrypted with a different set of one or more encryption keys, wherein the one or more different, respective encryption keys are identity-specific based on an identifier of an individual user and generated using a key generation process based on the identifier, wherein an authentication module provides the identifier to the key generation process and a transformation parameter generation process in accordance with system policies in order to generate one or more encryption keys, wherein the plurality of different objects are labeled, and consistently labeled objects are encrypted and decrypted with consistent encryption keys; and an authorizer that provides authorization criteria with the one or more images, the descriptive data in an encrypted state capable of being decrypted only if one or more authorization inputs satisfy the authorization criteria, wherein each of the plurality of different objects is decrypted with one or more keys generated by the key generation process using the identifier upon authorization of the user.
