Letter to the editor: “Edwards curve digital signature algorithm for video integrity verification on blockchain framework”

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.
