Publication number: 20160134652Abstract: A method for recognizing disguised malicious document, carried out by a computer system including a central processing unit (CPU), a memory, and a database storing rules for defining executable file and non-executable file, comprising steps of: receiving a static file through a network and an input/out interface; scanning the static file for a file header to determine if it is a non-executable file; analyzing file body of the non-executable file to locate components of an executable file and mark these positions; extracting components of the executable file from the non-executable file; concatenating the extracted components in accordance with a default rule or a heuristic rule to form a new file; and obtaining a new file that is executable, such that the received static file is a non-executable file having an embedded executable file, thus labeling the static file as a disguised malicious document.Type: ApplicationFiled: January 18, 2016Publication date: May 12, 2016Inventors: Ming-Chang Chiu, Ming-Wei Wu, Ching-Chung Wang, Che-Kuo Hsu, Pei-Kan Tsung

Patent number: 7549103Abstract: A data encoding method for error correction is provided. Before recording data into a recording media, the data are added with an Error Correction Code (ECC) comprising Check Sum on Row (CSR) and Check Sum on Column (CSC), thereby forming an ECC block. More than one ECC block are integrated into a data matrix, to resist longer burst errors of data. Finally, the data matrix is divided into several sectors and individual sector address information is added for each sector, thereby finishing the encoding process.Type: GrantFiled: May 10, 2006Date of Patent: June 16, 2009Assignee: Industrial Technology Research InstituteInventors: Ming-Chang Tsai, Che-Kuo Hsu, Kuo-Hsin Lai

Patent number: 7113114Abstract: Disclosed are a method and device of converting data words into code words. This method inserts 2p p guided bits before inputting each set of data words, performs a pre-defined operation, and generates 2p data sequences with different guided bits. It chooses q data sequences from the 2p data sequences for coding, performs a run length limited (RLL) coding with a coding rate m/n, and generates q (d, k) constrained code word sequences. Finally, an optimal (d, k) constrained code word sequence is selected from the q (d, k) constrained code word sequences. The device reduces the circuitry of the RLL coding applied guided scrambling without losing the control of direct current and low frequency components.Type: GrantFiled: October 4, 2005Date of Patent: September 26, 2006Assignee: Industrial Technology Research InstituteInventors: Chang-Po Ma, Yung-Chi Yang, Che-Kuo Hsu
