摘要：In this paper, we have proposed a new image steganography scheme which is a Fuzzy based selection ofwavelets. There are some attack forms to data and information. In consequence, today various efforts have beenconducted to take care of data security and overcome attacks is previously already there is a way to take care of datasecurity that is recognized by the name of cryptography. This system hides and recovers messages of substantial lengthwithin digital imagery while maintaining the original image size and dynamic range. The hidden messages can berecovered using appropriate keys without any knowledge of the original image. Image processing, error control coding,and spread-spectrum techniques utilized are described, and the performance of the technique is illustrated. Imagerestoration, error-control coding, and techniques similar to spread spectrum are described, and the performance of thesystem is illustrated. A message embedded by this method can be in the form of text, imagery, or any other digitalsignal.
