About the Talk

The speaker will review facts, goals and common architectures of mobile cloud computing systems, as well as mobile cloud computing challenges, and will focus on one of the major challenges in mobile cloud computing, Data Privacy, when users outsource their data to a cloud computing system. Data privacy can be violated by the cloud vendor, the vendor's authorized users, other cloud users, unauthorized users, or external malicious entities. Encryption is one of the solutions to protect and maintain the data privacy of cloud-stored data. However, encryption methods are expensive for mobile devices because of limited available resources on mobile devices, such as battery life.

This talk will include an overview of major security solutions to protect data privacy in mobile cloud computing, including a new light-weight data privacy method for mobile clients to store data on one or multiple clouds by using pseudo-random permutation based on chaos systems. The proposed method can be used in client mobile devices to store data in the cloud(s) without using cloud computing resources for encryption to maintain a user?s data privacy. We will consider JPEG image format as a case study to present and evaluate the proposed method. Our experimental results will show that the proposed method achieves superior performance compared to other encryption methods, such as AES and encryption on JPEG encoders, while protecting the mobile user data privacy.
