A Consortium Blockchain System for Verifying Digital Contents on Traditional Costumes

Many countries and organizations have an archive database for the digital preservation of cultural heritage. As recording cultural heritage data becomes more common, the importance of a reliable database is emphasized. However, if the verification of the produced digital heritage content is not correct, continuous errors are yielded in their applications and cultural heritage is misinterpreted. In this paper, we propose a consortium blockchain system for verifying digital cultural heritage contents. Blockchains, which have been applied to various fields recently, are a distributed data storage technology proposed by Satoshi Nakamoto. Blockchains are attracting attention as a technique for creating and storing reliable records owing to its property that it cannot be arbitrarily changed. We propose a verification system that is organized by three expert groups for assessment: researchers, curators, and artisans. The three expert groups review the digital heritage content and finally approve the content via a consensus process. To this end, the approved digital content is created as a block and stored in a blockchain record. We expect that the proposed consortium blockchain system will obtain efficiency and reliability in the screening process by leaving a reliable record of the digital content.
