A robust and secure scheme for image communication over wireless channels
K. Deergha Rao · 2005
Chaos based encryption may offer new quality in secure data transmission. Many chaotic image encryption and decryption algorithms have been reported in the literature. However, the feature of higher compression of the still image standard JPEG200 can not be achieved on the compression of chaotic images. The error resilient tools do not correct transmission errors. Furthermore, these tools do not apply to the image header which is the most important part of the codestream. To be suitable for wireless multimedia applications, JPEG 2000 has to be robust to transmission errors. Hence, in this paper, a scheme called chaotic JPEG2000 is proposed to utilize the higher compression feature of the JPEG2000 for secure image source coding. Further, the proposed chaotic JPEG2000 is robustified by turbo channel coding for image communication over wireless channels with burst errors. The efficacy of the proposed scheme is demonstrated though implementation results for an image communication over Gaussian impulsive noisy wireless channels.
