基于Bernstein多项式的数字图像分存

Digital image sharing based on Bernstein polynomial

数字图像分存技术将一幅秘密图像分解成为几幅无意义或者杂乱无章的图像进行存储或传输,以便增加图像信息的安全性。本文讨论了数字图像分存技术及其在信息安全中的应用,首先利用置乱变换对传输图像进行加密,然后利用Bernstein多项式对加密图像进行分存,并可以无误差的恢复出原图像。

Digital image sharing decomposes a secret image into several meaningless or disordered images, or camouflages it into several significant and meaningful images to store or transfers in order to enhance the security of the image information. With image information security as background, this paper proposes a new digital image sharing technology using Bernstein Polynomial, and the secret image can be recovered accurately without error.
