Analysis of Image Steganography Performance Check Using Bit Selection

Hidden communication is important since ancient times to provide the secrecy of information which may be for personal work or for professional work. In the ancient times cryptography was the main method for secret communication. In cryptography message is encrypted in some way but the existence of message is known to the third party which gives the possibility of hacking of the message by third party easily. Here comes the use of steganography which overcomes the drawback of cryptography. In steganography the existence of message is not known to the third party that makes it easy for two parties to communicate in an imperceptible manner. There are various techniques using steganography. Following work has been done using bit steganography in which bits of one image have been used which is called cover image to hide message image. This technique has been used on every bit of each pixel of cover image starting from LSB to MSB and then comparison of results has been done on the basis of mean square error ad peak signal to noise ratio.
