Abstract
Outsourcing data to cloud storage has become popular. Example systems such as Google Drive, Amazon S3 and Microsoft Azure are affordable and convenient, and provide scalable storage space. However, since the data management is left to third party, users no longer have physical control of their sensitive data, which raises new challenges in terms of data privacy. Data encryption provides confidentiality, but encryption alone is not enough since information may be leaked through the pattern in which users access the data. In this thesis, we implemented a Customized ORAM(C-ORAM) system that allows oblivious access to remotely-stored data in multi-user scenario. Experiments have shown that C-ORAM can effectively protect user's privacy as well as achieve low communication overhead at individual users.
