With the advancement of technology in communication network, it facilitated digital medical images transmitted to healthcare professional via internal network (e.g. PACs) or public network (e.g. Internet), in which pose a threat to digital medical images security, such as image tampering, and results a clinical misdiagnosis and treatment.Thus a reversible watermarking is introduced to maintain the integrity of medical images. There have been a number of researches done on watermarking scheme on single frame medical image, in which it is impractical in real world environment, where modalities are consist of multi-frames.This paper presented a conceptual design on developing a reversible watermarking scheme (tamper localization and recovery watermarking scheme) on medical images in multiframes environment. The watermarking process was applied on each frame in sequence. Time consuming has become a limitation of sequential watermarking process on multiframes medical images, especially in a large dataset of medical images. In order to solve the sequential problem concern, a parallel computing is recommended. Parallel watermarking could be achieved by utilised multicore technologies.
