Abstract
A method, system and product including obtaining a media sample of a media stream; retrieving from a database a media record that matches the media sample of the media stream; aligning the media record with the media stream, wherein aligning the media record comprises determining an offset from a start of the media record; comparing the media stream with the media record according to the offset; and upon identifying a semantic deviation between the media stream and the media record, determining that the media stream is semantically manipulated.
Claims20
A computer program product comprising a non-transitory computer readable storage medium retaining program instructions, which program instructions when read by a processor, cause the processor to:
- obtain a media sample of a media stream;
- retrieve from a database a media record that matches the media sample of the media stream;
- align the media record with the media stream, wherein aligning the media record comprises determining an offset from a start of the media record;
- compare the media stream with the media record according to the offset;
- and
- upon identifying a semantic deviation between the media stream and the media record, determine that the media stream is semantically manipulated.
A method comprising:
- obtaining a media sample of a media stream;
- retrieving from a database a media record that matches the media sample of the media stream;
- aligning the media record with the media stream, wherein aligning the media record comprises determining an offset from a start of the media record;
- comparing the media stream with the media record according to the offset;
- and
- upon identifying a semantic deviation between the media stream and the media record, determining that the media stream is semantically manipulated.
A system comprising a processor and coupled memory, the processor being adapted to:
- obtain a media sample of a media stream;
- retrieve from a database a media record that matches the media sample of the media stream;
- align the media record with the media stream, wherein aligning the media record comprises determining an offset from a start of the media record;
- compare the media stream with the media record according to the offset;
- and
- upon identifying a semantic deviation between the media stream and the media record, determine that the media stream is semantically manipulated.
