Abstract
The invention, which belongs to the monitoring equipment field, discloses a method for applying video content authentication to a vehicle-mounted video. The process employed by the invention is characterized in that a vehicle-mounted video content is calculated; the video content is extracted and effective analyzing is carried out; a vehicle-mounted video authentication center and perfect user authority management are established; watermark information is embedded into a local region formed by feature points; the watermark is embedded into the vehicle-mounted video; an authentication result is displayed; and data storage management is perfected and a report is formed automatically for outputting. With the method, completeness and authenticity of the vehicle-mounted video as the accident authentication evidence can be further improved.
Description
Technical field
The present invention relates to a kind of by video content authentication application in the method for Vehicular video, belong to monitoring equipment field.
Background technology
In real road travels, Vehicular video is that the strong evidence that can carry out accident responsibility identification that can enough provide is provided while having an accident, but, along with the fast development of information technology and constantly universal, to the bootlegging of these class multimedia messagess such as image, video, audio frequency, steal, distort and become very easy, the confidence level of Vehicular video content also will inevitably be under suspicion.
Summary of the invention
The problem existing for above-mentioned prior art, the invention provides a kind of by video content authentication application in the method for Vehicular video, further improve Vehicular video as integrality and the authenticity of accident authentication evidence.
To achieve these goals, the method that the present invention adopts comprises the steps:
1) adopt compressed domain video watermark embedded technology, in conjunction with real-time and incompressible Vehicular video content authentication algorithm, vehicle screen content calculated,
2) adopt the spectral method of space-time unite technology, ICA technology and figure, video content extracted and effectively analyzed,
3) set up Vehicular video authentication center, the user authority management of Erecting and improving, the conscientious certificate of safety distribution,
4) adopt the digital watermark of the anti-set attack embedding based on characteristic point regional area, watermark information be embedded in the regional area forming with characteristic point,
5) watermark is embedded in the significant semantic object of Vehicular video to the quick and Feature Points Matching in district and proofreaies and correct, geometric attack is put up a resistance,
6) by visualization interface, video demonstration, data storing and operation, control authentication result shown,
7) improve data storing manage public grace can, according to video content authentication softwares such as statistical analysis, report output, automatically form report output.
The present invention, by watermark embedded technology, carries out regional correction for Vehicular video, further strengthens the resistance to geometric attack; By visualization interface and perfect data storing, the certification authority of video shown and exported simultaneously, thereby further having improved integrality and the authenticity of Vehicular video as accident authentication evidence.
