  • There are gradually built on electronic commerce and business information system for the effective and automated use of internet while the mainstream of industry moves on information. It is necessary that a company should develop a electronic approval system because the business documents have application to an electronic commerce, business information system as well Currently, electronic approval system on groupware is using the way of inserting the image of an approval signature, which is vulnerable on a security by attacks of fraudulent use of electrical signature and eavesdropping on electronic documents. In this paper, we implementation XML form generator based on DTD having business documents structure for creating a valid business XML documents. we designed electronic approval system based on secured XML which transfers encrypted documents. For the security issues of written XML business documents, it makes use of the crypto algorithm having high performance transaction by the interchange of public key between a server and a client.

  • As the wireless communication technology developed, the Electric Commerce using a mobile was activated. WPKI was developed in order to guarantee the stability of the Electric Commerce but it is difficult to be ensured for the safe PKI service which is the same at the wire communication in the technical because of restriction of the mobile terminal. In this paper, we propose the authentication system for the electronic financial service which is safe and is effective in consideration of the restrictive characteristic of the mobile terminal. Moreover, the encryption algorithm for the safe electronic signature is proposed. In WPKI, this makes the cross certification of each certificate authority possible. Moreover, a stability was enhanced through the signature authentication using KCDSA and SEED algorithm.

  • The dorsal hand vein biometric system developed has a main objective and specific targets; to get an electronic signature using a secure signature device. In this paper, we present our signature device with its different aims; respectively: The extraction of the dorsal veins from the images that were acquired through an infrared device. For each identification, we need the representation of the veins in the form of shape descriptors, which are invariant to translation, rotation and scaling; this extracted descriptor vector is the input of the matching step. The optimization decision system settings match the choice of threshold that allows accepting/rejecting a person, and selection of the most relevant descriptors, to minimize both FAR and FRR errors. The final decision for identification based descriptors selected by the PSO hybrid binary give a FAR =0% and FRR=0% as results.

  • Information processing using computer in generalized in the office automation. In spite of to be integrate and concise form of document through computer network, signature of document with hand have processed as ever. The security on document flow out severely unjust by reason of increment inverse function of computer. Because of revelation secret of enterprise result from unjust outflow, lots of loss of self-enterprise is occured. In this paper, we used efficiently document using the method, electronic approval system with encryption, for the resolving above problems. Also we persue maintenance of security for the important document and process document signature rapidly. Finally, we design and implementation of electronic approval system that take one's share of function between server and client using to be transformed Vernam's encryption technique in stored document.

  • In this era of changing system, we may learn lesson from newly developed Uniform Electronic Transation Act(UETA) in 1999. Korea has its counterpart as the Basic Electronic Transaction Act and Electronic Signature Act made by 1999. While UETA stresses on transaction law between individuals, that of Korean stresses on the role of government in electronic transaction. Both laws have the common definitions as electronic record, electronic signature, however, UETA has its own definitions such as automated transaction, computer program, electronic agent, information, information processing system, and security procedure. Especially, transferable record in section 16 is one of the most unique concept which Korean law does not provide. Korean government is planning to introduce electronic note in the near future, which will make unprecedented reform in Korean financial industry. Since Korean law does not have such a concept as electronic note, revision of the law is expected soon. Korean law has its specialty which puts stress on cyber mall, authentication agency, and consumer protection. In U.S., the interpretation of law by court is important when they have disputes according to common law traditon. Studies on cases on disputes in U.S. is needed most for Korean application.

  • Purpose: The objective of the present study was to develop and evaluate a legal communicable diseases (LCDs) electronic system for infection control. Method: The system was developed through the procedure of analysis, design, implementation, application and evaluation, and was applied within an OCS (order communication system). Results: As indicated by the main menu, the present system is composed of an improved perception system for enhancing perception of LCDs, LCDs identification system, and improved efficiency in the report system. Detailed items included in the main menu are introduction and log-in screen, pop-up window for checking the outbreaks of LCDs, decision making icon, electronic signature icon, electronic report form, email system, etc. The total number of reports was greater after the application of the system (n=99) than before (n=80), and the adequacy of report time was statistically significantly higher after application of the system (P<0.05) Conclusion: The present system suggests a new method for LCDs report and infection control, and is expected to be adopted by other medical institutions in the future.

  • The area of business applications in the internet are extended enormously in result of fast development of computing and communication technologies, increase of internet use, and use of intranet/extranet in enterprise information system. Widely spread the use of the internet, there are various applications for Business to Business (B to B) or Business to Customer(B to C) model that are based on the intranet or extranet. This paper designed and implemented the Web-based Electronic Bidding System for Business to Business (B to B) model. The technical issues of electronic bidding system in the internet are involved in the connection between web client and server, electronic data interchange for the contract document, and security solution during the bidding and contracting processes. The web-based electronic bidding system in this paper is implemented using Java applet and servlet as a connection interface for web client and server, XML/EDI-based documents for a bid and a contract, and bidding server and notary server for enhancing the security using PKI(Public Key Infrastructure)-based public key cryptography, digital signature and Certification Authority(CA).

  • This thesis examines the problems faced in the electronic bill of lading for which improvements are necessary, and suggests various ways of overcoming those problems. First, to build a negotiation system for electronic B/Ls, active participation from related parties in addition to the government support is essential. Second, electronic B/Ls cannot be utilized within a short period of time in current commercial practices. Third, there should be infrastructure which connects all parties of international commerce through an electronic system. Fourth, instead of promoting mutual recognition through international treaty, there should be a plan which legally specifying mutual recognition between certification authorities. Fifth, it is needed to ease the strictness of electronic signature to promote the global negotiation of electronic B/Ls. Lastly, in prima facie weight of evidence, there was a significant difference with the Rotterdam Rules even in comparison with the Commercial Act which was amended with the significantly advanced rules on electronic B/L. He believed there should be a discreet consideration on these matters at the revision of the Commercial Act. For this, the government has to provide support more aggressively with more interest and commitments.
