报告题目：Fidelity Preserved Data Hiding in Encrypted Images Based on Homomorphism and Matrix Embedding  

报告人：廖群英教授

摘要：This talk proposes a data hiding scheme for high quality stego-images in the encrypted images based on a homomorphic encryption algorithm and matrix embedding method. We offer a matrix embedding method using Golay code, which has good embedding efficiency. In the proposed scheme, we pre-code the least significant bit (LSB) vectors of the cover image into the codewords before image encryption, so that we can implement the matrix embedding in the encrypted image. The experimental results show that the proposed scheme has excellent

security performance. We can get a high quality stego-image after the image decryption and recover the cover image into a fidelity image while providing considerable payload.
