Privacy protection of user-created content on multicore-based handheld devices

Privacy protection is an important issue in user created content. Especially, satisfying both real-time constraint and energy efficiency with handheld devices is challenging since the battery-operated devices need to compress and protect the user-created content in real-time. In this paper, we propose a multicore-based solution to compress and protect user created content, and evaluate the effectiveness of the solution in terms of both real-time constraint and energy efficiency. Based on the experimental results with MPEG2/AES-CCM software, we confirm that the multicore-based solution can improve the energy efficiency of a singlecore-based solution by a factor of 1.8 under the real-time constraint.
