  • Patent number: 9021586
    Abstract: Apparatus and methods are provided that prevent cross-site request forgery at one or more web servers. A proxy dynamically monitors web server responses to client requests for content having a selected characteristic, adds a hidden token to content identified as having the selected characteristic prior to serving the content to a requesting client, and stores a copy of the hidden token for later verification that client request content sent to a web server is authentic. The proxy monitors client request content sent to the one or more web servers for a selected characteristic, and allows client request content having the selected characteristic to be processed by a web server application only if the client request content includes a token previously provided by the proxy and only if the token has a value matching a stored token value for the respective client.

  • Patent number: 8831570
    Abstract: Systems and methods for implementing a location token service (LTS) to enhance the security of mobile device identity tokens by using the location of the mobile device to augment the tokens. The LTS enforces re-authentication (login) of the mobile device to one or more applications if the mobile device moves beyond a threshold distance from the location of the last use of the token within a time period defined in a temporal threshold. The LTS increases authentication strength and drastically reduces the potential for spoofing or otherwise permitting unauthorized access to one or more applications on the mobile device.

  • Publication number: 20070039043
    Abstract: The present invention provides a method and apparatus for logging off of a global session and releasing resources from applications associated with the global session. When a user logs off of a single sign on (SSO) global session a Distributed Global Logoff Manager tracks each SSO family member application and any other application to which a user has logged on during the global session, and simulates the user logging off from each individual application to which the user ends the global SSO session. Distributed Global Logoff allows each application in a SSO family to participate in the logoff so that each application can free its resources immediately rather than waiting for a session time out to release application resources. Resources allocated to various applications such as data base connections, programs stored in memory and transactional data stored in memory are released.
