ELECTRONIC STEGANOGRAPHY SIGNATURE OF VIDEO DATA
The article examines principles for building of an asymmetric system of video data authentication. The suggested scheme applies a method of digital watermarks. To provide for the authenticity, we have used the robust hashing function. The cryptographic basis is the scheme based on the Johansson electronic signature absolute stable scheme with the bit generation and verification. As a result, we ensure protection against external and potential internal intruders under conditions of the high error level at video compression. The article gives the experimental results of video data compressed with H.264 codec at variable stream speed. The experimental comparison is performed with one of the advanced asymmetric authentication schemes using digital watermarks based on the fragile electronic digital signature and fragile simulation plug. It is qualitatively discussed potential threats to the authenticity for the video sequence and analyzed how this scheme can face these threats.
