Abstract: An apparatus and method for storing security information are provided. The apparatus is generally an electronic device that includes a memory configured to include a secured region to store security information and a processor configured to electrically connect with the memory. The processor is further configured to execute an application program configured to store the security information in a first secured region, to receive a request to store the security information from the application program, and to store the security information in a second secured region different from the first secured region in response to the request.

Abstract: An apparatus and method for performing a cryptography function on an electronic device are provided. The method includes executing an application on the electronic device, requesting, by the application, to use a security library, loading the security library in a remote process on the electronic device, and communicating, by the application, with the security library in the remote process.

Abstract: An apparatus and method for securing a personal identification number (PIN) on a mobile device are provided. The method may include receiving a request for the PIN from a secure element on the mobile device, instantiating a trusted user interface (TUI), collecting the PIN via the TUI, and securely transmitting the PIN from a trusted execution environment (TEE) associated with the TUI to a secure element (SE).

Abstract: A method and apparatus for synchronizing shared data in mobile terminal and server. A disclosed method includes, creating a new data entry in a user contact information document of a first user on an address book server and granting a second user access to the data entry, wherein the user contact information document includes an address entry for sharing the data entry with the second user.

Abstract: A method and apparatus for synchronizing address book in mobile terminal and server client is disclosed. A disclosed method comprises, upon initiation of execution of an address book application in a mobile terminal, transmitting a start signal having an address book identification to an address book agent. In response to the start signal, receiving synchronization information for synchronizing an address book of the address book application, the synchronization information being generated by the address book agent in response to update information from an address book server. The method further comprises synchronizing the address book of the application using the synchronization information.
