Abstract
Video integrity is a crucial aspect of forensic science that guarantees the reliability and validity of visual evidence used in court proceedings. In an era where digital alteration tools are readily available, ensuring that video recordings remain unmodified is essential to upholding the integrity of the legal system. Our technique offers a new, simple way to check the integrity of video data. Our approach makes use of the BLAKE2b hash function, the blockchain, and the Edwards Curve Digital Signature Algorithm. Video segments are pre-recorded video clips for which signatures are generated and kept in chronological blocks. To provide an additional degree of protection, the signature from the prior block is kept in the present block. These signatures are validated at the moment of validation. According to experimental data, our method performs faster and more securely than state-of-the-art approaches. With negligible extra storage requirements, our approach can detect every kind of counterfeit on any video file, by anybody, at any time. Our security analysis further demonstrates that our approach is resistant to a wide range of attacks, such as side channel, collision, key substitution, and chosen message assaults.
期刊介绍：
Science & Justice provides a forum to promote communication and publication of original articles, reviews and correspondence on subjects that spark debates within the Forensic Science Community and the criminal justice sector. The journal provides a medium whereby all aspects of applying science to legal proceedings can be debated and progressed. Science & Justice is published six times a year, and will be of interest primarily to practising forensic scientists and their colleagues in related fields. It is chiefly concerned with the publication of formal scientific papers, in keeping with its international learned status, but will not accept any article describing experimentation on animals which does not meet strict ethical standards.
Promote communication and informed debate within the Forensic Science Community and the criminal justice sector.
To promote the publication of learned and original research findings from all areas of the forensic sciences and by so doing to advance the profession.
To promote the publication of case based material by way of case reviews.
To promote the publication of conference proceedings which are of interest to the forensic science community.
To provide a medium whereby all aspects of applying science to legal proceedings can be debated and progressed.
To appeal to all those with an interest in the forensic sciences.
