  • Patent number: 6915347
    Abstract: A method for grouping Human Interface Devices (HIDs) into a multi-head display is provided. The HIDs are identified as either “primary” or “secondaries”. A computational-service policy module is consulted when a new HID connects to the network. If the HID is identified as a secondary, the module consults all servers within a group to see if the primary presently has an active session connected to any of the servers. If the primary is being controlled by the same server to which the secondary is connected, the session connection information for the primary is augmented to indicate that the secondary is attached to the same session, and this information is disseminated to the interested software entities. The associated session may then provide multi-head outout to the secondary. If the primary is being controlled by another server in the group, the secondary re-attaches to the server that is hosting the primary.

  • Patent number: 6711681
    Abstract: A system and associated method for authorizing, or withholding authorization of, user access to a selected computer application or other resource, based on the user's response to one or more user authentication tests. If the user satisfies one or more authentication tests but satisfies less than all the tests, the system optionally allows the user access to a selected subset of the resource. Alternatively, the user loses access to a selected subset of the application for each test not satisfied by the user. An authentication test or its associated weight may change at a selected time, and the selected time may be determined with reference to a time at which the resource changes.

  • Patent number: 6687823
    Abstract: A system and associated method for authorizing, or withholding authorization of, user access to a selected computer application or other resource, based on the user's response to one or more user authentication tests. If the user is presented with two or more authentication tests, each with an associated test weight, the system optionally sums the weights of the tests satisfied by the user; and if this sum is greater than a selected test score threshold, the user is granted access to the resource. Alternatively, the user is granted access to selected subsets of the application, including an empty or non-empty default subset, depending upon the sum of the weights of the tests satisfied by the user. An authentication test or its associated weight may change at a selected time, and the selected time may be determined with reference to a time at which the resource changes. A smartcard may be used to respond to one or more authentication tests.

  • Publication number: 20020169967
    Abstract: Embodiments of the present invention are directed to a method and apparatus for multiple token access to thin client architecture session. In one embodiment, a user is associated with a session using an authenticated token. A user may access a session by authenticating the user's identity. An authenticated token for the user is created and the user is granted access to the session. As a result, the user will be able to access the session without the physical token by authenticating the user's identity using a passphrase or biometric identifier. In one embodiment, a user is able to access a session from one terminal when the session is already being accessed from another terminal. The user presents an authenticated token associated with the session, and the session is disconnected from the old terminal and input and output information is rerouted to the new terminal.

  • Publication number: 20020046300
    Abstract: The present invention provides a mechanism for grouping several standard computers and making them act as one to generate a multi-head display. In one embodiment, the computers are designated as either “primary” or “secondary” terminals. In one embodiment, a set of policy modules decides whether and what type of computational service should be provided to the terminal. For a secondary terminal, the module determines whether the primary terminal of the group has an active session connected to any of the servers. If the primary terminal is being controlled by the server to which the secondary terminal is connected, then session connection information for the primary is augmented to indicate that the secondary is attached to the same session. If not, then the secondary is commanded to attach to the server hosting the primary terminal. A special session is presented where the primary is not attached to any server.
