CONFIDENTIAL INFORMATION SECRET METHOD

The article deals with the issues of hiding text information in a graphic file. Most often, one or two least significant bits of the image pixels are modified. To do this, each byte of the secret message is divided into 8 or 4 parts. The use of the least significant bits of the graphic file for t...
