The study aims to preserve integrity of JPEG bitstream transmitted in Wireless Multimedia Sensor Networks (WMSNs) environment, lightweight complex process that is proposed to parse bitstream of encoded medical image and formulated the encryption process for that represented bit of Diff value in DC coefficients rather than appended bits of ACs coefficients. Our choice deals with low down complexity by encrypting limited numbers of DC coefficients versus ACs coefficients per block, or even all image blocks. This model may be utilized in building a secure framework of remote image analysis and archiving center for that transmitted medical images from body sensors and clinician, or even other remote imaging center with high integrity and low complexity. The experiments result shows that the proposed approach gives an interesting and remarkable result to preserve the medical image integrity. The obtained results are discussed in details.
