Secure Authentication using Dynamic Virtual Keyboard Layout
Abstract-Virtual Keyboard authentication has helped users to protect their username and passwords from being captured by key loggers, spyware and malicious bots. However Virtual Keyboard still suffers from numerous other fallacies that an attacker can take advantage of. These include click based screenshot capturing, over the shoulder spoofing and co-ordinate position noting. To overcome these drawbacks, we have designed a virtual keyboard that is generated dynamically each time the user access the web site. Also after each click event of the user the arrangement of the keys of the virtual keyboard are shuffled. The position of the keys is hidden so that a user standing behind may not be able to see the pressed key. Our proposed approach makes the usage of virtual keyboard even more secure for users and makes it tougher for malware programs to capture authentication details.
