A Study on Authentication Mechanism to Ensure the Reliability of Content Distribution Using Log Monitoring and Encoding of OPSs

摘要

New paradigm digitalization in cultural content enables illegal copy and distribution of music and/or movie in the same quality as original at a rapid pace. This causes the situation that blames the illegal distribution of cultural content on illegal OSP (Online Service Provider). While OSPs observe the relevant copyright law and take filtering technological protection measures, they keep distributing illegal content, disturbing a market order and infringing rights and interests of users and copyright holders evading filtering technology, omitting and forging/ falsifying distribution related log record. Existing regulations and filtering technological protection measures are not enough to prevent illegal distribution of content. This paper examines information protection technology with multiple-signature OSP and user access control as a specific solution and proposes a log data authentication system.
