  • China has recently (28 August 2004) adopted a new act legalizing the electronic signature. This new act provides electronic signatures with the same legal status as handwritten signatures, and states that on-line certification providers will have to be created in order to ensure the security of on-line operations made using said signatures. This new act is intended to increase Chinese electronic business, and thus to raise the revenue China can expect from said business. And the law grants electronic signatures the same legal effect as handwritten signatures and seals in business transactions, and sets up the market access system for online certification providers to ensure the security of e-commerce. As Internet trade requires a reliable third party to identify the signers, the credibility of online certifying organizations is significant for the transaction security. So, considering the weakness of China's social credibility system, the law regulates that the online signatures certification providers should be approved and administered by governments.

  • One of the most secure ways of maintaining the confidentiality and integrity of electronic information is to use electronic signatures. So, in this paper, we developed guideline on electronic signatures for EMR(electronic medical record) based on the Medical Law and the Electronic Signature Act. This guideline is intended to introduce EMR easily in the medical field and to facilitate the promotion of EMR. We developed it through consulting from the advisory committee that was made up of experts in the fields of medical record, EMR system and electronic signatures. The contents of the guideline consist of subject and time stamp of electronic signatures, validity of a certificate, management of electronic signatures and custody and management of EMR. In the future, we will develop practical cases and promote educations and publicities of them to use in the medical institutes and EMR system related industries.

  • Uniform Electronic Transactions Act (1999) Drafted by the National Conference of Commissioners on Uniform State Laws. The Act allows the use of electronic records and electronic signatures in any transaction, except transactions subject to the Uniform Commercial Code. The fundamental purpose of this act is to remove perceived barriers to electronic commerce. The Act's a procedural statute. It does not mandate either electronic signatures or records, but provides a means to effectuate transactions when they are used. The primary objective is to establish the legal equivalence of electronic records and signatures with paper writings and manually-signed signatures. With regard to the general scope of the Act, the Act's coverage is inherently limited by the definition of "transaction." The Act does not apply to all writings and signatures, but only to electronic records and signatures relating to a transaction, defined as those interactions between people relating to business, commercial and governmental affairs. The exclusion of specific Articles of the Uniform Commercial Code reflects the recognition that, particularly in the case of Articles 5, 8 and revised Article 9, electronic transactions were addressed in the specific contexts of those revision processes. In the context of Articles 2 and 2A the UETA provides the vehicle for assuring that such transactions may be accomplished and effected via an electronic medium. At such time as Articles 2 and 2A are revised the extent of coverage in those Articles(Acts) may make application of this Act as a gap-filling law desirable. Similar considerations apply to the recently promulgated Uniform Computer Information Transactions Act (UCITA). Another fundamental premise of the Act is that it be minimalist and procedural. The general efficacy of existing law, in an electronic context, so long as biases and barriers to the medium are removed, confirms this approach. The Act defers to existing substantive law. Specific areas of deference to other law in this Act include: i) the meaning and effect of "sign" under existing law, ii) the method and manner of displaying, transmitting and formatting information in section 8, iii) rules of attribution in section 9, and iv) the law of mistake in section 10.

  • Many organizations today use patch management systems to uniformly manage software vulnerabilities. However, the patch management system does not guarantee the integrity of the patch in the process of providing the patch to the client. In this paper, we propose a method to guarantee patch integrity through dual electronic signatures. The dual electronic signatures are performed by the primary distribution server with the first digital signature and the secondary distribution server with the second digital signature. The dual electronic signature ensures ensure that there is no forgery or falsification in the patch transmission process, so that the client can verify that the patch provided is a normal patch. The dual electronic signatures can enhance the security of the patch management system, providing a secure environment for clients.

  • This article discusses and analyses several issues regarding to the Electronic Signature and the Electronic Certification. The objects of the analyse are the each paragraphs of the Korean Electronic Signature Act of 1999 and that of the Korean Electronic Transaction Basic Act of 1999 in comparing to the paragraphs of the Electronic Signatures in Global and National Commerce Act' (E-Sign) of 2000, U.S.A. and that of the Draft UNCITRAL Model Law on Electronic Signature of 2000. The main issues discussed herein are the scope of the electronic signature, the definition of the electronic signature, permission of services to the non-authorized certification service providers, the effect of the electronic signature, the liability of the concerning parties of the electronic signature including liability of the certification service providers, that of the subscribers and that of the relying parties. This paper also discusses the problems of the possibility of issuing the electronic negotiable commercial papers, the validity of the electronic signatures done by electronic agents, the authority certificate, mutual certification of the foreign certification service providers, the permission of the electronic notary service, the problems of the consumer protection and the possibility of issuing electronic insurance policy, etc. The writer concludes by suggesting some measures that will activate the use of electronic signatures under the korean circumstances.

  • At Eurocrypt'91, D. Chaum and E. Heyst introduced the notion of group signatures, which allow members of a group to make signatures on behalf of the group while remaining anonymous. This paper first presents a new type of group signatures with observers. In group signatures with observers, our solution is the most practical group signature scheme, under the assumption that Chaum's electronic wallet is secure.

  • The purpose of this paper is to analysis the legal aspects of e-commerce, particularly those relate to electronic contract, in China On 23 November 2005, the United Nations General Assembly adopted a Convention on the Use of Electronic Communications in International Contracts, known popularly as the Electronic Communications Convention. China signed it but the convention is not binding yet as it still requires the ratification by three states. On the other hand, China adopted a new act legalizing the electronic signature in 2004. This new act provides electronic signatures with the same legal status as handwritten signatures. But the efficiencies that business hopes to achieve through electronic commerce are not completely reflected in the legal processes necessary to support those hopes.

  • There have been active research efforts in the development of a dual-use millimeter-wave radiometer as an aircraft landing aid in low visibility conditions. In this paper, we constructed a radiometer operating at the Ka-band where it is relatively easy to build RF components. The radiometer is used to collect radiometric signatures of some vehicles and land surfaces. Measured signatures suggest that vehicles with metallic surfaces yield signatures markedly different from nearby land surfaces so that they can easily be detected by a simple radiometer.

  • This paper focuses on identifying which appliance is currently operating by analyzing electrical load signature for home energy monitoring system. The identification framework is comprised of three steps. Firstly, specific appliance features, or signatures, were chosen, which are DC (Duty Cycle), SO (Slope of On-state), VO (Variance of On-state), and ZC (Zero Crossing) by reviewing observations of appliances from 13 houses for 3 days. Five appliances of electrical rice cooker, kimchi-refrigerator, PC, refrigerator, and TV were chosen for the identification with high penetration rate and total operation-time in Korea. Secondly, K-NN and Naive Bayesian classifiers, which are commonly used in many applications, are employed to estimate from which appliance the signatures are obtained. Lastly, one of candidates is selected as final identification result by majority voting. The proposed identification frame showed identification success rate of 94.23%.

  • In this study, we have investigated the correlation of far-field detection sensitivity of surface plasmon resonance (SPR) biosensors with optical signatures associated with the near-field overlap of biomolecules. The results confirm a direct relation between the far-field and near-field parameters, particularly for optical signatures defined in terms of lateral electric field components that are tangential to the interface and thus continuous across the interface. The overall correlation between near-field optical signatures and far-field resonance shift exceeded 97%. The results can be highly useful to evaluate detection sensitivity of SPR biosensors that take advantage of complex structures for localization of surface waves.
