چکیده:

In many steganographic systems LSB filliping is used to hide messages in spatial domain. This method, with ease of implementation as its advantage, is a weak approach against statistical attacks. Methods that can avoid statistical attacks offer a small payload capacity. It has been shown that ±۱ embedding is much harder to detect than LSB filliping. The ±۱ embedding method does not introduce the same asymmetries into
the stego image histogram. In this paper we propose a method that increases the capacity of ±۱ embedding while maintains the same security level.
