Abstract: The embodiments herein provide a system and method to enable dynamic authentication for unlocking the computing devices. The embodiments also provide a system and method for authenticating a pattern through the preset user-specified grids for capturing and comparing pattern-based authentication systems for accessing computing devices. The users are also enabled to customize a grid depending on preset rules. The system also provides a suggestion of the smallest pattern drawn on a grid. The present dynamic pattern-based authentication system provides enhanced security as compared to conventional pattern-lock systems.

Abstract: A method and system for billing a calling party for an unanswered call attempt is provided. A first network component receives a call attempt from the calling party and routes the call attempt to a second network component for establishing a communications link between the calling party and a called party. The second network component redirects the call attempt unanswered by the called party to the voice server. A billing management application, provided for managing the billing of the calling party, detects the redirection of the call attempt and indicates to the first network component to disable billing the calling party for the unanswered call attempt. The billing management application, in communication with the voice server, initiates billing of the calling party based on billing criteria, via the second network component instead of the first network component, for utilizing one or more services provided by the voice server.
