Abstract

A Computer Authentication System, CASA; a software application which performs file authentication functions in any Microsoft® Windows® registry based computer operating system. The CASA system modifies the manner in which Microsoft® Windows® executes application programs. This modification allows the CASA software to easily specify authentication functions to be performed on executed applications, including, but not limited to virus scanning, security access validation, license auditing, version checking, file change detection, and/or usage logging. CASA operates by altering the Windows® registry so that the CASA application starts before execution of the user specified application, applies authentication functions to the user specified application, and takes appropriate actions based on the results of said authentication. This method provides a significant improvement over existing authentication procedures because the CASA application executes only when needed, executes without user intervention, allows multiple authentication functions to be performed at once, and does not use up resources on the host computer when not in use.
