Steganography is the technique which is used to provide secured communications between two or more users . This technique basically works on the principal of breaking the image into multiple parts and then hiding the data which is to be transmitted to other user’s . By using this technology we can hide and send the information in the from of digital images , videos and audios . We have used multiple algorithms to provide extra security to the encrypted image . Algorithms used include LSB (Least Significant Bit) and the MSB (Most significant Bit). For the encryption and the decryption of the image we use the AES (Advanced Encryption Standard) Algorithm . Iterative approach is used by the design with the block size of 128bit and key size 256bit.
