SIE: An Application to Secure Stereo Images Using Encryption

To provide the security to image contents, most encryption techniques are designed for synthetic and real images which is, however, not applicable to stereo images. Stereo images generally consists of two views (left and right views) of a scene with known viewpoints. The only way is to encrypt both left and right images separately. To address this issue, this chapter introduces a new and effective encryption technique to encrypt left and right stereo images simultaneously to produce a single encrypted image. A decryption process is finally introduced to generate left and right stereo images from the final encrypted image. The extensive experiments on different stereo images demonstrate the efficiency and the robustness of the proposed encryption technique.
