Verification of digital video information authentication At present numerous devices that display video data not in an analogous, but in a digital format appeared. Security and authentication of received digital data is becoming a point of high importance. Leading manufacturers of security video systems that employ digital data receivers are working on the development of new devices. Software engineers study possibilities of the implementation of image authentication algorithms by means of marking an image by means of watermarks. This method requires significant investments. Less simple and cheap authentication methods are based on a method of digital image comparison. This study dwells on the issue of picsel data authentication by means of comparison of color code totals. A number of alternatives of image comparison algorithms were applied. Reliability and efficiency of these algorithms were analyzed. Three basic formats that are widely used in security and photo business were taken for the analysis. The developed software facilitates to perform a graphic analysis of used algorithms. The software was developed for the purpose of the study and further can form a part of system authentication.
