A Web Archiving Method for Preserving Content Integrity by Using Blockchain

摘要

A web archive system has become an essential topic for preserving historical information for descendants with the explosive growth of web data. The reference model for an Open Archival Information System (OAIS) has been providing an excellent guide for a long-term archiving system, and most of web archive systems follow this guide. However, there is still a weak point in terms of content integrity due to the archival web data could be altered by unauthorized manner. In this paper, we proposed the BCLinked (Blockchain Linked) web archiving method which uses blockchain technology and an extended WARC (Web ARChive) file format to ensure the content integrity. Furthermore, we confirmed the proposed method ensures content integrity through the experiment.
