It's getting harder to post pirated videos to the internet every day thanks in part to new tech like the video fingerprinting system that NEC has just announced. The new fingerprinting tech aims to help identify illegally uploaded video on the internet using a visual identification.
The tech takes a fingerprint from the original movie and promises a high degree of accuracy. The system claims to be more efficient than the current method of using watermarks. New key features of the system include video identification using a modified signature.
This feature apparently has something to do with the brightness of the video in a region that can be compared between the uploaded video and the original source. By comparing these brightness values, the system ensures a high rate of identification and a low false positive rate. The NEC tech requires little processing power and the company claims that a home PC can be used to identify 1000 hours of possible matches in a second.
