IMAGE ENCRYPTION METHOD BY USING BIT-PLANE COMPRESSION: A REVIEW ARTICLE

Abstract

Remembering or privately saving the key for encrypting the hidden picture is quite a task. Moreover, the encrypted image could arouse the suspicion of the invaders. In this paper, using the bit-plane compression and Lagrange interpolation formula, a novel hidden image sharing scheme with additional steganography and repairable capabilities is proposed. The proposal suggests that the user choose an ostensible image, such as a popular character image, to disguise his hidden image as the cover image to improve protection. Specifically, to create meaningful shadow images, a protected image is split into three shares and concealed in the cover image. Then, three shadow images, such as the mobile, the laptop, and cloud storage, are distributed to three separate devices. The user can recover the initial hidden image and the cover image losslessly by collecting any two shadow images. Furthermore, when the smartphone or laptop is lost, the proposed device is easily repairable. The review of the framework reveals that not only does the proposal achieve theoretical information security, it is also technically realistic.
