  • Publication number: 20160134652
    Abstract: 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.

  • Publication number: 20140150101
    Abstract: A method for recognizing malicious file has steps: receiving a static file through a network or an input/out interface to be stored in the memory; defining suspicious positions where components of a malware are possibly encrypted in the static file; decrypting the suspicious positions to identify a PE header and a shellcode; extracting the PE header and the shellcode terms in segments; and determining whether the PE header and the shellcode terms can be assembled into an executable binary which indicates a recognition of the malicious file.

  • Publication number: 20130179975
    Abstract: A method for extracting the genetic fingerprinting of a malicious document file includes the steps of establishing a database to store a plurality of genetic fingerprinting data of the first malicious document, then retrieving a document file sent via the Internet, and then proceeding with multi-point detection and extraction to the document file, so as to obtain a multi-point section, then comparing and analyzing the multi-point section with the plurality of genetic fingerprinting data of the first malicious document to confirm whether the multi-point section program code of the document file matches a malicious feature, thereby achieves the goal of extracting the content information of the document file and converts it into the genetic fingerprinting data of a new malicious document.

  • Patent number: 8059521
    Abstract: An optical recoding carrier and an information recording method applying an amplitude shift keying (ASK) method or further a DC-biased ASK method are provided, wherein at least one periodically undulated section and at least one non-periodically undulated section are formed on the optical recording carrier to indicate specific information. The information recording method can be embodied as an addressing method of an optical disk for recording address information of tracks of the optical disk. A continuous track structure is provided on the optical recording carrier to save the available recording space and improve the information reading precision of the optical recording carrier. Furthermore, a signal generating apparatus and an information reading apparatus applied in the information recording method are provided.

  • Patent number: 7646826
    Abstract: A type dependency modulation method with type control is integrated with type control code words in traditional type dependency modulation. It increases the effect of DC component control in the overall encoding procedure. In this method, a specific type-control code word is inserted at certain intervals in the encoding procedure, increasing the selectable code words in subsequent encoding procedures, thereby improving the DC component control ability.

  • Patent number: 7549103
    Abstract: 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.

  • Patent number: 7113114
    Abstract: 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.
