Abstract :
A storage system constructed by a wide-area distributed file system of open source software has been requested to ensure the certain existence of the non-falsification data by a trusted third party. We developed an integrity verification application using timestamp mechanism for Gfarm which is a wide-area distributed file system of open source software made in Japan. However, the application remained low performance. This paper explains an improvement method of the application and reports its performance in a basic evaluation.
