A message security processing system and method for Web services are provided. In the message security processing system in which messages are exchanged between a client and a server with a SOAP-RPC format, each of the client and the server includes: a security interface allowing information related to digital signature, encryption, and timestamp insertion to be set in a security context object for an application program to meet security requirements of the client or the server; a security handler receiving the security context object from the security interface, and performing security processing of a request message by calling security objects stored in a request queue of the security context object one by one in order or performing security processing of a response message by calling security objects stored in a response queue of the security context object one by one in order; and an XML security unit supporting an XML security functions by called by the security handler.

The invention relates to an apparatus and method for detecting an illegitimate change of web resources, which is capable of detecting whether or not HTML, XHTML and XML documents, general text documents, binary data of graphic files linked to HTML document and the like are illegitimately changed using XML digital signature and XML encryption when inquiring corresponding web page. It is characteristic of the present invention to confirm in real time whether or not the web page is illegitimately changed by inserting an illegitimate change detecting information into the web page by a web server administrator and executing corresponding web page through a web browser by a user.

In the inter-working method of wireless Internet (gateways) according to the present invention described above, DIAMETER which is the first version of the IETF-RFC standard of mobile IP application is applied to the application scenario based on wireless Internet gateway of a home network, not on FA or HA of Mobile IP. After all mobile communication providers connect to wireless Internet, subscribers are not bounded to the network of their mobile communication provider and have the freedom to select any external wireless Internet portal site and use the service of it. Such a wireless Internet connection method will make wireless Internet contents popular in the open wireless network epoch and provide wireless Internet contents providers with an excellent chance. The authentication of the wireless Internet gateways of other networks, authorization, accounting management, structures and techniques proposed by the present invention can give solutions to security problems of wireless internet gateway (ex WAP G/W) that have not overcome, and provide reliability to wireless Internet electronic commercial trade service.

A system for performing face registration and authentication using face information, and a method thereof. A set of readily distinguishable features for each user is selected at a registration step and only the set of features selected at the registration step is used at a face authentication step, whereby memory use according to unnecessary information and amount of data calculation for face authentication can be reduced. Thus, the present system has an advantage in that identity authentication through face authentication can be performed even under restricted environments of a USB token or smart card with limited resources. The present system further has advantages in that authentication performance is improved, as readily distinguishable feature information is used, and the time for face authentication is reduced, as face authentication is performed using the SVM built by using the optimal set of readily distinguishable features at a training step.

In an apparatus for authenticating a user by employing feature points of a fingerprint image of the user, a fingerprint image input circuit scans a fingerprint of a user to be registered to provide a first fingerprint image and a fingerprint of a user to be authenticated to provide a second fingerprint image. A host provides registered feature points data corresponding to the first fingerprint image and target feature points data corresponding to the second fingerprint image. A security token circuit estimates a position difference and a direction difference between pairs of a registered feature point and a target feature point and corrects the two feature points based on the position difference and the direction difference to provide authentication result data.

A 4-state bar code printing and reading system for use in physical distribution-related services such as mail pieces, receptacles, reception and management forms or the like, and a method for controlling the system are disclosed. The 4-state bar code printing system comprises a bar code information acquiring section for acquiring, storing and determining a mail piece sorting information; an information recorded density enhancing section for evaluating a value of a character, by using of a compression method depending upon a type of the information and digit, which are determined by the bar code information acquiring section; an input information encoding section for arranging the values of the bars produced by the information recorded density enhancing section in order of values of bars of the 4-state bar code, and dividing the values into groups each consisting of 3 bars; an error correcting codeword producing section for producing an error correcting codeword based on the result of the information encoding section the input value of an error correcting level; and a print frame producing section for arranging the error correcting codeword produced from the error correcting codeword producing section and the data produced from the information recorded density improving section in order of a start bar, a data, an error correcting codeword, and a stop bar, to print a 4-state bar code print font on a mail piece.

This invention is related to a system and a method for reading high precision printed barcodes and their specification verification. The presented invention has a technique of reading both logistic sorting barcode (one or two dimension) and multi-layered structure barcode such as four-state barcode for automatic postal matter sorting. The invention also investigates height of high densely reduced barcodes in more than 3 steps, and precisely measures and reads the values of black bars thickness and white spaces. Previous techniques used laser beam for reading barcodes, but could not read barcodes, which have print density of less than 1/100 mm&tilde;1/1,000 mm unit, and, it was also impossible to read precise specification values in case that barcode specification was composed of length unit indexes. The presented invention overcomes the previous said problems by using a laser diode array.

The present invention relates to a direct memory access controller, specifically to a direct memory access controller which controls the direct memory access between internal modules and high speed external memories such as SDRAM(Synchronous Dynamic RAM) in high speed digital signal processors having burst transmission feature. The direct memory access controller comprises a plurality of direct memory access controller circuits, a direct memory access bus arbiter, and a direct memory access bus bridge connecting a direct memory access master bus and a direct memory access slave bus and providing a data transmission path between external high speed memories and input/output devices according to a signal from the direct memory access controller which is connected to said master bus.

There is disclosed a node booting method in a high-speed parallel computer. Other than the method in which the system using a conventional network down loads the operating system kernel image from the boot server, the method according to the present invention provides an environment by which a boot can be progressed in parallel and a boot progress state can be monitored through a console terminal, thus improving a boot speed. The node booting method according to the present invention is comprised of a first step of finding a logical boot path using a node construction table managed by a firmware; a second step of determining boot subject nodes so that copy of an operating system kernel image can be made simultaneously; a third step of copying effective portions of the operating system loaded at the memories onto the subject nodes; a fourth step of informing a boot node of the node state and to display the boot progress state on a console terminal at the start and end time of the booting; and a fifth step of simultaneously starting execution at the remaining portions of the copied operating system when the kernel image are completely copied onto all the nodes.
