Abstract: Image statistics protection is the necessary segment in communiqué plus multi-media globe. At some point in accumulating and contributing, keep away from 3rd party entrance of statistics is the confront lone. As long as protection of statistics is the smart job and talent too. A lot of defence procedures are utilized in current duration. Security perhaps given of a statistics is changing the unique in to a number of unidentified structure, indications, draft and so on, which is not recognized by anybody. The finest method of image statistics protection is “Cryptography”. Crypto implies “concealed‟ and graphy implies “writing”. 2 procedures of cryptography: encryption and decryption. Encryption attains the exchange by grouping a key of unique statistics keen on illegible shape known as encoding. Renovating of encrypted statistics into unique shape is known as decoding or decryption. In cryptography key, code or password plays a very important role. This study shows the concert of encoding plus decoding of an image utilizing a solitary key procedure and experienced on a number of images and presents well outcomes.The LSB supported methods are extremely accepted for Steganography in spatial domain. The easiest LSB method purely swaps the LSB in the cover image among the bits from clandestine (secret) data. Additional highly developed methods utilize a number of measures to recognize the pixels wherein LSBs can be swape by means of the bits of clandestine data. The method which is known as DCT:  the placing of clandestine data in carrier depends on the DCT coefficients. Several DCT coefficient assessments over appropriate verge are a possible position for placing of clandestine data.

KEYWORDS: Steganography, Discrete Cosine Transform, Least Significant Bit.
