Systems for identifying misappropriation of forensically-watermarked video content. A method embodiment for forensic watermarking commences upon identifying video sources. A video is partitioned into frame ranges or “chunks”. Different watermarking schemes are applied to the chunks to generate different watermarked versions of each chunk. Upon receiving a request from a user to view a requested video, a digital signature is generated from a set of request attributes such as a user ID or session ID. A video stream is assembled wherein the stream chunk order comprises a particular recoverable sequence of the differing watermarked chunks, where the sequence is based on bit sequences of the digital signature. A misappropriated video or portion thereof can be analyzed to identify the particular recoverable sequence or portion thereof. Based on the recoverable sequence, the digital signature can be recovered, and based on the digital signature, the source of the misappropriation can be determined.
A method for forensic watermarking of video content, the method comprising:
A computer readable medium, embodied in a non-transitory computer readable medium, the non-transitory computer readable medium having stored thereon a sequence of instructions which, when stored in memory and executed by one or more processors causes the one or more processors to perform a set of acts for forensic watermarking of video content, the acts comprising:
A system for forensic watermarking of video content, the system comprising:
