Abstract: An apparatus for transmitting/receiving voice data capable of estimating voice data of re-synchronization section and method thereof are provided to improve communication quality by using property of voice data value indicating slow change. An apparatus for transmitting/receiving voice data capable of estimating voice data of re-synchronization section includes a transmission unit(10) and a receiving unit(20). The transmission unit generates a key re-synchronization frame by inserting vector information about a voice data together with key re-synchronization information to transmit the key re-synchronization information, and transmits a generated key re-synchronization frame. The receiving unit receives the key re-synchronization frame from the transmission unit, and predicts the voice data of the re-synchronization section by extracting the vector information about the voice data.

Abstract: A flash memory erasing apparatus and method is provided to prevent data from being read by unauthorized person by erasing data stored in the flash memory forcedly. In a flash memory(200) including a central processing unit(230), a connection circuit(140) between the central processing unit and the flash memory prevent data from the central processing unit from being transmitted to the flash memory after receiving an erasing signal which is generated in case of deleting the data of the flash memory or compulsorily disassemble the apparatus. A control logic(150) deletes the data of the flash memory by using power of a connected battery(110) in case that the erasing signal is generated.

Abstract: A method for inserting vector information for predicting voice data of a key re-synchronization section, a transmission method and a method for predicting voice data of a key re-synchronization section using vector information are provided to predict a voice data value of a mute section by periodical key re-synchronization in direction wireless environment by using characteristics of a voice data value showing smooth variation, thereby improving communication quality in a receiving terminal. An inputted voice is encoded as voice data(200,210). It is determined whether a frame of voice data to be transmitted is a key re-synchronization point(220). If so, voice data of a current frame is deleted(230). From a difference between voice data of a previous frame and the voice data of the current frame, voice change direction information is obtained(231). By using the extracted voice change direction information of the voice data, vector information is configured(232). The vector information and key re-synchronization information are inserted into a section where the voice data is deleted in order to configure a key re-synchronization frame(233). After that, the configured key re-synchronization frame is transmitted(234).

Abstract: A process classification/execution controlling device for strengthening DAC(Discretionary Access Control) and a method thereof are provided to prevent probable authority elevation by dividing program objects executable in a system into a CUS(Command, Utility, and Safety) group and a DVO(Discretionary, Vulnerable, and Outer) group, and making a process subject of a DVO group member execute a CUS group member program. An application end includes a program group management program(3) requesting program classification to the objects classified into the CUS group(1) and the DVO group(2). A kernel module(5) performs CUS/DVO group classification by responding to a received request, and controls execution of the program by linking with group information of the executable programs while storing a group of the processes executed in the system, information for an execution object repository(7), and consistency information to a kernel memory. The execution object repository classifies/stores the CUS and DVO group. A program classifier(51) classifies the execution object programs stored to the execution object repository into the CUS a DVO group.
