Abstract: A method and a corresponding terminal for an encrypted call, to resolve disadvantages of an encrypted call that is implemented relying on a key management center (KMC) and network reconstruction, and reduce costs. The method includes establishing, by a first terminal, a circuit switched call with a second terminal, determining, by the first terminal using the circuit switched call, a key for performing an encrypted call with the second terminal, and performing, by the first terminal, an encrypted call with the second terminal using the key.

Abstract: A computer device that can login to a personal account located on a server via the internet, the computer device includes communication circuitry that is configured to access the internet, a user interface to receive a request to login to the personal account, a memory that stores information, and processing circuitry that controls the communication circuitry to transmit to the server a request to login to the personal account, analyzes a type of the personal account, calculates a distance between the computer device and another computer device, controls the communication circuitry to transmit a notification to the another computer device in response to the processing circuitry determining that the type of personal account is a specific personal account and the distance being greater than a first predetermined distance, and transmits a request to the server to logoff the personal account when a permission is received.

Abstract: An optical medium containing virtual write protect information can be recorded in drives and systems without first changing the write protection from on to off by receiving valid user input The virtual write protection may also be enabled or disabled by additional information on the disc.

Abstract: The present invention is directed to a system, method and program product for providing secure communications in a virtual universe. A system is disclosed that includes a system for allowing a first avatar to request a secure communication mode and for allowing a second avatar to accept the secure communication mode. Once accepted, a secure session is initiated within the virtual universe between the first avatar and the second avatar and at least one feature of the virtual universe is altered to effectuate the secure communication mode.
