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.
