Sending image in a plain form has a high risk for the data being vulnerable to steal. Thus,
due to reducing the risk, data security techniques should be implemented. Data security …

Least Significant Bit (LSB) is a very popular method in the spatial domain of steganographic
images. This method is widely used and continues to be developed to date, because of its …

Public networks such as the Internet are becoming more sophisticated, faster, and cheaper,
