Disclosed is a method and system for efficiently backing up a virtual machine file. A virtual machine file is logically divided into a plurality of fixed-size blocks of similar size, for example, a number of 1 MB data blocks. An MD5 hash value is generated from the contents of each block. Each block is written to a file having a filename that includes a filesystem-compliant form (e.g., hexadecimal form) of the computed MD5 hash value. A backup device includes a directory hierarchy having a plurality of first-level directories corresponding to the first two bytes of the hash value, and a plurality of second-level directories corresponding to the next two bytes of the hash value. The blocks are uniquely stored in the directory corresponding to the byte value pairs of the hash. The present disclosure provides data integrity checking and reduces storage requirements for duplicative, redundant, or null data.

A method of detecting malicious binary executable files is accomplished by inputting a binary executable file; converting the binary executable file to byte hexadecimal text strings; calculating the frequency of each byte pattern in the byte hexadecimal text strings; selecting characteristic byte pattern frequencies as discriminating features; classifying the discriminating features as malicious or benign; labeling the binary executable file as malicious or benign; and outputting the labeled malicious or benign binary executable file.

A system and method for message filtering are disclosed. A conversion target letter table is generated which stores information on letters that may be used to elude filtering, the table storing the hex code information of each letter that may be used for eluding filtering and the conversion letter information regarding the conversion letter to which each letter is to be converted. A hex code of a message text inputted by a user is compared with the hex codes of the table, and when a conversion target letter is included, it is converted to the conversion letter stored in the conversion target table associated with the letter. When the conversion is completed, it is determined whether or not pre-configured prohibited words are included in the converted message; and message filtering is performed.

A method and apparatus for recording data concerning a system is provided. The apparatus comprises a memory card, such as a COMPACTFLASH card, and a processor unit, such as a T2CAS processor unit. The memory card includes a supplemental file that contains instructions as to what data is to be recorded and when the recording should start and stop. To conserve space the supplemental file is written as a sequence of hexadecimal characters whose position in the sequence and binary bit value indicates which data is to be recorded and when. A lookup table can be used to interpret the supplemental file. The processor unit includes or is coupled to a memory card reader / writer.

The invention provides a data encryption method. The data encryption method comprises the following steps that first data is acquired, wherein the first data is fingerprint data, identity card data, adigital cipher and / or MF card data; the first data is converted into hexadecimal coded second data; and the second data is subjected to a hardware encryption mechanism and a software encryption mechanism to acquire encrypted data. According to the data encryption method, by means of the process that the first data is acquired and converted into the hexadecimal coded second data, and then the second data is encrypted to acquire the encrypted data, the security of the data can be guaranteed.

The invention provides a migration apparatus and method for converting an application program of a mainframe system into an appropriate application program for an open system. The migration apparatus includes: a source obtaining module connected with the mainframe system, and decoding and obtaining sources of work-specific application programs made of Extended Binary Coded Decimal Interchange Code(EBCDIC) in binary form; a code conversion module converting the respective sources of the work-specific application programs obtained by the source obtaining module into American Standard Code for Information Interchange (ASCII) code, hexadecimal characters being converted to correspond to ASCII code using a previously set hexadecimal code conversion table; a compiling and link processing module compiling the sources of the work-specific application programs converted by the code conversion module and then bundling the compiled sources of the work-specific application programs with corresponding work application programs; and an executable file generation module generating executable files in binary form from the work-specific application programs processed by the compiling and link processing module to execute them in an environment of the open system. The migration apparatus and method efficiently reuse a conventionally used application program via the rehosting process of converting a mainframe system into an open system.

The invention relates to a BIOS (basic input output system) debugger and a BIOS debugging method. The BIOS debugging method comprises a single chip microcomputer, an FPGA (field programmable gate array) chip, an RAM (random access memory) and two seven-segment digital tubes, wherein the FPGA chip is connected with the single chip microcomputer, the RAM and the two seven-segment digital tubes. BIOS burning data signals in a series transmission format output by a control computer is converted into the BIOS burning data signals in a parallel transmission format to be output to the FPGA chip by the single chip microcomputer. The BIOS burning data signals in the parallel transmission format is stored into the RAM by the FPGA chip, the BIOS burning data signals read in RAM 30 are converted into data signals in an SPI (serial peripheral interface) communication protocol format and then are output to a computer to be tested, so that the POST (power on self test) of the computer to be tested is conducted. The POST data signals output by the computer to be tested are also converted into two-digit hexadecimal data to be output to the two seven-segment digital tubes for displaying.

The invention provides a watermark processing method and system. Watermark character string information are coded into quinary bitstreams, quinary check beginning information and quinary check ending information are added in the quinary bitstreams, and therefore quinary embedded information is acquired; pdf files are loaded, the pdf files are unified on a standard blank character in a hexadecimal mode, a preset mapping relation between the pdf files is represented according to the quinary content and the hexadecimal of the standard blank character, and the content of the standard blank character is modified to embed the quinary embedded information into the pdf files; the pdf files are analyzed to acquire the content of the stand blank character, the quinary embedded information is extracted according to the preset mapping relation, the quinary bitstreams are extracted from the quinary embedded information according to the quinary check beginning information and the quinary check ending information, and the quinary bitstreams are decoded into the watermark character string information.

A method and system of storing and accessing documents on a computer file system utilizing a file system-independent key for use in an index-less browser caching mechanism. The present invention is a method and system for storing a resource such as a document or group of documents on a computer file system using a Universal Resource Indicator (URI) as the file name by generating a unique system-independent key from the URI for use in an index-less browser caching system. The invention takes into account the various file entry length limitations enforced by each unique file system by converting the specified URI into a key containing hexadecimal values of the key's characteristics. In this fashion, an index-less browser caching system such as a Web browser of a VoiceXML browser is created that is file system-independent.
