Latest Patents
One of Sharp's latest patents is a "System and method for unified sign-on." This invention provides a mechanism for signing on a user of a first domain into an affiliate application in a second domain. When a user requires access to the affiliate application, a request generates a ticket that identifies the user. This ticket is passed to an adapter, which redeems it for the user's credentials, such as a valid userID/password combination for the affiliate application. The system also includes services for issuing and redeeming tickets, managing the registration of affiliate applications, and ensuring the encryption of stored records.
Another patent by Sharp is also titled "System and method for unified sign-on." This system allows a user from a first domain to access a second domain. A request originates in the first domain to perform an action in the second domain, indicating the user on whose behalf the request was made. The adapter in the second domain requests an access token for the corresponding user, utilizing a mapping table to identify the correct user. Once identified, the access token is returned to the adapter, which then carries out the requested action by impersonating the user of the second domain.
