Abstract
Security has become a priority in any security system. Computer applications, Internet system applications, etc. how millions of users use the Internet. This is a research project suggests an information processing algorithm Security system using PNG (Portable Network Graphics) pictures. To our knowledge, there are very few jobs available is present in the PNG archives of steganography. A Least Significant Bit (LSB) encoded stenographic system code is slightly more advanced and is built in the Matlab programming language. The proposed system is often different from other default approaches that use the LSB input method, with the next point. This: The first point about the character set of the secret message used. It automatically detects the character set for private messages. and determine whether the text is written in Latin (only 8 bits per character) or Latin/Arabic (16 characters per character). The approach presented is implemented using special Matlab code functions and encoding algorithms. Two main algorithms for deleting encrypted messages sequentially.
