The need for security is increasing in the modern digital world. Since, the user information is more vulnerable to attackers it is necessary to protect that information from the hand of hackers. So here arises the need for a strong password. In the digital world password plays a main role and need for a strong password is essential. Password plays an important role in different applications ranging from e-mail to online banking. Most of the present technology makes use of combination of alpha-numeric characters as password. These are more vulnerable to hackers. These can be traced using key loggers or key tracing software's. One alternative is using the virtual keyboard but still the password is alpha-numeric characters. These can be cracked used dictionary attack. Different attempts have been made to overcome these limitations one of the modern approaches in mobile is by using patterns as passwords. In this proposed method, we aim at creating a strong password mechanism using the picture patterns. The traditional alphanumeric password is replaced with the picture patterns. For enhancing the security AES encryption, LSB steganography and Top-k retrieval mechanism are used.
