Abstract
A system and method for authenticating an encoded multimedia stream are disclosed. In one embodiment, one or more digital signatures associated with one or more decodable units in the encoded multimedia stream are generated, in real-time. Further, the generated digital signatures are embedded into the encoded multimedia stream.
Claims22
A method, comprising:
- generating, in real-time, one or more digital signatures associated with one or more decodable units in an encoded multimedia stream;
- and
- embedding the generated one or more digital signatures into the encoded multimedia stream.
A system, comprising:
- a transmitter, wherein the transmitter comprises:
- a multimedia signature generator, wherein the multimedia signature generator generates, in real-time, one or more digital signatures associated with one or more decodable units in an encoded multimedia stream and wherein the multimedia signature generator embeds the generated one or more digital signatures into the encoded multimedia stream.
A non-transitory computer-readable storage medium for authenticating an encoded multimedia stream using digital signatures, when executed by a computing device, cause the computing device to:
- generate, real-time, one or more digital signatures associated with one or more decodable units in an encoded multimedia stream;
- and
- embed the generated one or more digital signatures into the encoded multimedia stream.
