A Review towards Enhancing Authentication Scheme Using Image Fusion and Multishared Cryptography

Passwords are used for user authentication, validation, and verification in various software applications ( may be Commercial, or Research based). All the existing schemes which are used to generate the password will always provide enough scope for the Intruder ( Cracker) to crack or guess the password. All the existing schemes of password generation works on a basic assumption that the resultant password should be easy to remember for a user. This ultimately brings the downfall of the scheme. Therefore, a Password Generator Scheme is proposed here which will restrict the Intruders to crack the password or a scheme should exist which will cause sufficient delay in cracking of a password so that the Generator of the password will change the previous password. Here a strong password generator scheme is proposed by using Image Fusion & Visual key Cryptography.
