Privacy protection is an important issue in user created content. Especially, satisfying both realtime 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 execution 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 2.2 under the real-time constraint.
