Abstract
A security-enhanced login technique that provides a convenient and easy-to-use two factor technique to enhance the security of passwords without requiring any changes on the server side of a client-server network. The technique employs a convenient and easy-to-use two-factor technique to generate strong passwords for Web and other applications. In this technique, a convenient or personal device such as a mouse is used as the other factor besides a user password. A secret stored in the mouse or other personal device is hashed together with the password entered by a user and the server ID, to generate a strong, server-specific password which is used to authenticate the user to the server. This password enhancement operation is carried out inside the personal device.
