A novel method for buyer-seller authentication using blockchain technology

Abstract

A disseminated and carefully designed media exchange system is proposed dependent on the blockchain framework.
Present day interactive media does not protect self-retrievable data of exchange trails. For instance, computerized
duplicates of profitable fine arts, innovative media and excitement substance are dispersed for different purposes including
displays and exhibition accumulations. Unique media is frequently altered or messed with to create false publicity over
web-based social networking. Anyway there is no current algorithm that can without much of a stretch recover either the
exchange trails or the change accounts. This proposed algorithm will help resolve such issues with the help of blockchain
and digital watermarking. The special watermark data comprises of two snippets of data: 1) cryptographic hash that
provides us with exchange trails and 2) an image hash to detect tampered media. When the watermark is separated, initial
segment of the watermark is passed to a conveyed record to recover the verifiable exchange trail and the last part is utilized
to distinguish the altered locales. The thesis work diagrams the prerequisites, difficulties and exhibits the verification of
this idea. The framework proposed in this paper aims to address a solution for copyright protection and illegal distribution
of multimedia contents using the cutting edge blockchain technology.
