摘要：Computers are being used worldwide. The internet connects the world as one; giving rise to both the positive and the negative. Cyber-crime is a huge issue which can be resolved by some approaches. In this paper an approach is introduced to ensure the security of data. Steganography and cryptography are merged together in order to obtain a secure and reliable way of transmitting data. In this paper encrypted data is transmitted using steganography to thwart off attackers. Noise is introduced to the image at sender end and is reduced at receiving end. In this way a clear image is received instead of a corrupted image and the mere existence of the message is hidden from unauthorized third parties.
