20120258699 | METHOD FOR OPERATING PORTABLE TERMINAL TO REDUCE POWER DURING SUPPORT OF COMMUNICATION SERVICE AND PORTABLE TERMINAL SUPPORTING THE SAME - A method for operating a portable terminal so as to reduce power consumption during the support of a communication service and a portable terminal supporting the same is provided. The method includes activating a Radio Frequency (RF) communication unit, downloading a part of data of predetermined contents through the RF communication unit, buffering the downloaded part of the data in a buffer so as to output the buffered downloaded part of the data, and executing an idle time for terminating or reducing a power supply of the RF communication unit when the downloading of the part of the data of the predetermined contents is completed. | 10-11-2012 |
20130219177 | SECURE DATA PROCESSING DEVICE AND METHOD - A secure data processing device is provided. The device includes a main Operating System (OS), a plurality of main processes which are executed under control of the main OS and which are associated with each other, a secure OS which is simultaneously operated with the main OS, and at least one secure process which is executed under control of the secure OS and which corresponds to at least one of the plurality of main processes. If at least one of the plurality of main processes is in an abnormal operation state, an operation of the least one secure process is interrupted and initialized according to a request of the main OS. | 08-22-2013 |
20130219188 | APPARATUS AND METHOD FOR REPRODUCING CONTENTS IN ELECTRONIC DEVICE - 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. | 08-22-2013 |
20130219192 | CONTENTS SECURITY APPARATUS AND METHOD THEREOF - A contents security apparatus for preventing Standard Definition (SD) contents which are protected targets of a level which is relatively lower than that of High Definition (HD) contents from being processed through a trust zone of a processor thereof and a method thereof are provided. The contents security apparatus includes a processor for operating a first Operating System (OS) and for storing authentication information of at least one or more contents and a second OS for limiting access to the first OS, wherein the first OS decrypts and processes contents with a high security level and wherein the second OS decrypts and processes contents with a low security level. | 08-22-2013 |
20130219507 | METHOD AND APPARATUS FOR PROTECTING DIGITAL CONTENT USING DEVICE AUTHENTICATION - 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. | 08-22-2013 |
20140140256 | METHOD FOR OPERATING PORTABLE TERMINAL TO REDUCE POWER DURING SUPPORT OF COMMUNICATION SERVICE AND PORTABLE TERMINAL SUPPORTING THE SAME - A method for operating a portable terminal so as to reduce power consumption during the support of a communication service and a portable terminal supporting the same is provided. The method includes activating a Radio Frequency (RF) communication unit, downloading a part of data of predetermined contents through the RF communication unit, buffering the downloaded part of the data in a buffer so as to output the buffered downloaded part of the data, and executing an idle time for terminating or reducing a power supply of the RF communication unit when the downloading of the part of the data of the predetermined contents is completed. | 05-22-2014 |
20150243063 | METHOD AND APPARATUS FOR DISPLAYING BIOMETRIC INFORMATION - An electronic apparatus is provided. The electronic apparatus includes obtaining a first image including at least a part of an iris, applies an image effect to an image region corresponding to at least a part of the iris, and displays the image region through a display connected to the electronic apparatus, thereby preventing iris information from being exposed. | 08-27-2015 |
20150371051 | METHOD AND APPARATUS FOR PROTECTING DIGITAL CONTENT USING DEVICE AUTHENTICATION - 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. | 12-24-2015 |
