Abstract: This paper proposes a new method for password security and the password is encrypted and decrypted by using watermarking, Conventional password encryption method for user substantiation is to convert the password into hash values. These hash-based password methods are comparatively agile because those are dependent on text and renowned cryptography. However, those can be vulnerable to cyber-attacks by hash-based cracking tool. Attackers can rigorously totalize an original password from hash value when that is comparatively simple and modest. Hence, many hacking contretemps have been occurred consistently in systems endorsing those hash-based schemes. Contrasting from the conventional methods based on hash and text we propose Enhanced text and image cryptography using watermarking method. The user chooses source image, output image, information which is text or image is to be hidden along with security key. The information given by user is hidden in source image by water marking process that includes Cipher text and public channel. To retrieve the hidden information the decrypted key is used which is same as the encrypted key. Hence information which is text or image is recovered without any loss.
Keywords: Cryptography, Watermarking, Image Hiding, Encryption and Decryption.
Scope of the Article: Image Security
