Abstract
Secondary content in encrypted for distribution to client terminals by selecting at least a portion of raw encrypted audio-video data (REAVD) that is provided on a media article as an encryption key, encrypting secondary content using the encryption key, and storing encrypted secondary content at a remotely located host. The media article can then be used for providing access to the encrypted secondary content to client terminals by receiving encrypted secondary content at a client terminal, extracting a decryption key from a media article encoded with REAVD, the decryption key being determined by at least a portion of the REAVD, using the decryption key to decrypt the secondary content, and outputting the decrypted secondary content from the client terminal.
Claims12
A method comprising:
- sending encrypted content to a client terminal, wherein the encrypted content comprises at least one live audio-video data stream;
- keying the encrypted content to a decryption key, wherein the decryption key is configured to be encoded on and extracted from a media article distinct from the encrypted content;
- and
- wherein the client terminal is configured to read the decryption key from the media article and decrypt the encrypted content sent according to a defined algorithm using the decryption key.
An system comprising:
- a processor operably coupled to a media reader, the processor configured to:
- receive encrypted content comprising live audio-video data;
- extract a decryption key from a media article distinct from the encrypted content;
- and
- decrypt, according to a defined decryption algorithm, the encrypted content using the decryption key.
A method comprising:
- sending encrypted content to a client terminal, wherein the encrypted content comprises multiple live audio-video data streams;
- keying the encrypted content to multiple decryption keys, wherein each of the decryption keys are configured to be encoded on and extracted from differing segments of a media article, and wherein the client terminal is configured to decrypt, according to a defined algorithm, at least a portion of the encrypted content based on one or more of the decryption keys.
