A Hybrid Approach to Resist Shoulder Surfing Attack
In this proposed scheme a new method is introduced for password authentication. Various methods for authentication are proposed in the past years but many of them are vulnerable to shoulder surfing attacks. Most users are more familiar with textual password than graphical password. But in that many security problem is created. So some year ago many text based graphical password scheme has been proposed .but unfortunately none of exiting password schemes is both secure and efficient enough. In proposed scheme a new hybrid approach is used for authentication .this method promises to provide better security and prevents shoulder surfing attacks. The proposed system uses a grid in which user has to click on the selected grid to authenticate to the system. For every login, a grid will change with the help of directional arrows. During each login the grid will appear in different way.
