A user device may strengthen the protection level of a digital content by dividing the security and normal modes and performing an operation. In order to further strengthen the protection level of the digital content, the user device may determine whether the main operating system is hacked or not, and blocks the operation in the secure mode. Otherwise, the device authorization information indicating the device security level of the user device is authorized by the content service server, and the user device blocks the operation in the secure mode according to the result.

Method and apparatus for protecting digital content using device authentication

An electronic device includes a processor and a memory functionally connected to the processor. The electronic device acquires user's biometric information through a biometric sensor, determines virtual biometric information corresponding to the acquired biometric information, and transmits the virtual biometric information to an external electronic device through communication circuitry. The electronic device may include the biometric sensor, the communication circuitry, and the memory may be electrically connected to the biometric sensor and the communication module and store instructions to be executed by the processor.

Electronic device for processing biometric information and method of controlling same

A method and an apparatus for performing authentication are provided. The method includes performing, by a first authentication unit in a first electronic device, authentication with respect to a second electronic device that requests authentication through a first communication mode and when the second electronic device is authenticated, transmitting first information used for controlling the first electronic device to the second electronic device through the first communication mode and transferring second information indicating that the second electronic device is authenticated to a second authentication unit in the first electronic device.

Method for performing authentication and electronic device thereof

An apparatus and a method for outputting contents where an Output Protection Level (OPL) has been set to an extension device in an electronic device are provided. The apparatus includes a secure processor for decrypting and decoding contents where a right to use the contents has been set using a secure Operating System (OS). When receiving an external output request for contents whose external output is not allowed, the secure processor stops generating of decoded data transmitted to an extension device.
