摘要：Steganography is the art of passing information in a manner that the very existence of the message is unknown. Steganography is an alternative to cryptography in which the secrete data is embedded into the carrier in such way that only carrier is visible which is sent from transmitter to receiver without scrambling. The goal of steganography is to avoid drawing suspicion to the transmission of a hidden message. This paper presents a review on various quantization tables used for Steganography. Firstly, the concept of steganography is introduced and then different quantization tables, such as 8x8 and 16x16, both on gray scale and colored images are reviewed
