Image steganography using vector quantization and discrete cosine transform

摘要

Application of the camouflaging technique achieves the goal of secure communi- cation for secret images. The camouflaging technique in image, proposed by this article, com- bines lossy image compression technique vector quantization (VQ), lossless data compression and the cryptographic encryption/decryption procedure to decrease its deeply embedded secret data and increase its level of security.
