  • Publication number: 20070185980
    Abstract: A method of automatically adjusting device settings can include a step of associating devices with device location beacons and associating users with user location beacons. The devices can be linked to a network that includes a location server. The location server can automatically determine location based relationships between the devices and the users based upon positions of the device location beacons and the user location beacons. For each device, applicable ones of a set of established policies can be determined. For each device, applicable policies can be determined based upon at least one of a physical location of the device, a relative position of the device to the users, and a relative position between the device and other devices. The selected policies can be conveyed to the devices through the network connection. Each device can automatically adjust at least one device setting in accordance with the policies.

  • Publication number: 20070180082
    Abstract: A method for utilizing networked devices can include a step of receiving a network job associated with a network user. A location of the network user can be automatically determined. One of many possible networked devices can be dynamically selected based upon the determined user location. The network job can be assigned to the selected device.

  • Publication number: 20070143830
    Abstract: A method, apparatus and system are provided for preventing unauthorized access to a password-protected system by authenticating a user over a communication medium. Authentication of a user is accomplished by sending to the user, via a communication medium, an instruction that includes at least one element in which the user is directed to provide input that is not alphanumeric. Examples of such elements include, but are not limited to, a directive that the user place an object in a specific position on a display screen or that the user touch a specific location on a touch screen display. Once the user replies to the instruction over the communication medium with the requested input, an authentication server receives the input and checks it to determine whether the input complies with the issued instruction.

  • Publication number: 20060294388
    Abstract: A system (10) and method (100) for enhancing security and session persistence can include the steps of authenticating (102) a user within a proximity of a first client device (19), sending (104) authentication data from a wireless scanning device (14) to a security server (16), and initiating (108) a client session at the first client device. Note, authentication data will be sent (106) from the security server to the application server. The method can further automatically log off (110) the user upon leaving the proximity and save the client session at an application server and further automatically authenticate and log-on (114) the user to the client session when entering a proximity of at least one among the first or a second client device. The method can detect (112) the presence of the user using an RFID scanner that detects an RFID tag from a badge held by the user.
