US Patent 7222363 Device independent authentication system and method

A system is disclosed which facilitates authentication processes with web-enabled wireless devices, including those that do not support the use of cookie files. To facilitate such authentication, a web server analyzes an HTTP request file from a communication device for the presence of security token data. Where none is found, a client is directed to a login page for input of authentication data, such as a user name and password information. Upon proper authentication, the client's communication device is issued a security token using standard HTML—INPUT tags. Thereafter, the web server determines if each additional HTTP request file received from the client includes a security token before responding to the request.
