For a variety of reasons, the number of medical disputes is continuously rising. Due to the intrinsic qualities of medical treatments, one would find it more apt to subject medical disputes to general conflict resolution procedures rather than to once-for-all decisions under legal suits. To address the increasing medical disputes with greater professionalism and efficiency, the Medical Disputes Mediation Act was enacted and a medical dispute mediation system put in place, while drawbacks have been blamed to both. The current mediation procedures require the respondent's agreement as a disclosure requirement. A reasonable improvement to this would be to amend the regulation of agreement supposition, or to enforce procedural participation only to public health facilities managed by the national or regional government. Furthermore, small claims cases of 20 million KRW or less in claim may be considered for conciliation-prepositive principle. The concentration on small claim medical disputes is a phenomenon that can be addressed by carrying out maximum authentication commissions or similar measures, one of the solutions by enhancing the public trust in the Korea Medical Dispute Mediation and Arbitration Agency. The proper management of medical authentication teams is one way to address the existing problems in the authentication system. For this, the number of team members shall be increased under more flexible authentication procedures. All indemnity resources for medical accidents of force majeure must be borne by the Government, for it is the body principally responsible for social compensation. Placing this cost on the establisher of the subject medical facility holds the possibility of violating fundamental rights. While the costs for subrogation payment system for damages may be borne by the healthcare facility establisher, a deposit-based system must be created for cases in which the facility shuts down, without holding the responsibility for accident cause. Such change to a deposit-based system will evade the controversies of unconstitutionality, etc.

The user authentication and authorization in the current home network system almost works at home and home users, sometimes novice, should manage the system directly. This situation can make much of troubles, sometimes cause some suity problems. Moreover, the system costs high to build up, demands special user knowledge to maintain. In this paper, we propose the user authentication and authorization system based on remote management server to solve the problems, designed and implemented the system. To verify the system performance and function, we built a demo system for information appliances. The results of the test, the authentication and authorization function works well and reliably.

This paper presents a user authentication scheme for healthcare application using wireless medical sensor networks, where wireless medical sensors are used for patients monitoring. These medical sensors' sense the patient body data and transmit it to the professionals (e.g., doctors, nurses, and surgeons). Since, the data of an individual are highly vulnerable; it must ensures that patients medical vital signs are secure, and are not exposed to an unauthorized person. In this regards, we have proposed a user1 authentication scheme for healthcare application using medical sensor networks. The proposed scheme includes: a novel two-factor professionals authentication (user authentication), where the healthcare professionals are authenticated before access the patient's body data; a secure session key is establish between the patient sensor node and the professional at the end of user authentication. Furthermore, the analysis shows that the proposed scheme is safeguard to various practical attacks and achieves efficiency at low computation cost.

This paper describes the design and implementation of the video conferencing system using public key infrastructure which is used for user authentication and encryption. Public key infrastructure reinforces the authentication process for conference participant, and the symmetric key system blocks malicious access to information and protect conference control information. This paper shows the implementation of the trans portation layer secure protocol in conformity with Korea public key authentication algorithm standard and symmetric encryption algorithm (DES, 3DES and AES) for media stream encryption. In this paper, we deal with two ways of protecting information : transportation layer secure protocol secures user authentication process and the conference control information; while public key-based authentication system protects personal information of users when they connect to the network. When distributing the session keys for encryption, Internet Key Exchange is used for P2P communication, and secure protocol is employed for 1 : N multi-user communication in the way of distributing the public key-based en-cryption key.

The Web or Mobile channel of previous Web access authentication system for a payment only provides the authentication of remote users, and does not provide the authentication between a user and a bank/financial institution. Therefore, this paper proposes the Transaction Certificate Mode(TCM) for a payment which can preserve the mutual authentication between a user and a bank/financial institution for Web-based payment systems. The proposed system has designed for wireless network instead of Secure Electronic Transaction (SET) designed for wired electronic transaction. In addition, this system with TCM is able to support an account-based transaction for wireless networks instead of a disadvantage of SET such as a card-based transaction for wired networks. Therefore, customers can check their balances without logging on their bank's web site again due to mutual authentication between a customer and his bank/financial institution.

Nowadays, authentication is essential to identify the legal users in a network communication. Usually, there are few wars to achieve authentication over a publicly accessible network system in order to protect certain private data from the unauthorized users, ranging from simple ID/Password to Biometrics System. One of the most active areas in OTP(One Time Password) research today aims at exploiting OTP to provide authentication in the finance and security industry. OTP is usually discarded once it has been used. this prevents huge loophole of traditional authentication system which employs the same ID and Password every time. However this OTP system also has its weaknesses in surviving some attacks. this paper proposes an advanced OTP protocol using PingPong-128 without loop hole of pre-existing OTP.

This paper proposes a method to shut out all of the not certified network access packet by embodying the two-factor(MAC ADDRESS, ID/PASSWORD) authentication system. The Authenticating Gateway System takes over central server's policy and permit or hold up the packet by inherited policy. And checks the whether or not patched the OS version and getting influenced from computer virus. And takes the information about client's resources(H/W, S/W) without Agent in the client. That makes more stability of network operating circumstance and fast facing the attack from hackers. In the fixed mobile network circumstance, This method provides more simplicity and less expenses than IEEE802.1x authentication system(cisco nac).

This paper proposes a two-phase server login authentication system by XML-Signature schema extension to protect server's information resources opened on network which offer various web contents. A proposed system requests and publishes XML-based certificate through on-line, registers certificate extension information provided by CA(Certification Authority) to XCMS(XML Certificate Management Server), and performs prior authentication using user's certificate password. Then, it requests certificate extension information added by user besides user's certificate password and certificate extension information registered in XCMS by using SOAP message, and performs posterior authentication by comparing these certificate extension information. As a result, a proposed system is a security reinforced system compared with existing systems.

Compared with the existing bar code system, RFID system has lots of advantages such as it identifies automatically massive objects. We might anticipate RFID technology will be a substitution for an optical bar code system in the near future. However, their feature that uses radio waves may cause various security problems. Many kinds of solutions have been researched to overcome these security problems. In this paper, we analyze the previous proposed protocols. And then, we categorize RFID authentication into two types according to the synchronization requirement between a Back-end Database and a Tag. In addition, we introduce the previous proposed approaches to tag search problem in RFID authentication. And we propose an efficient method which provides fast tag search by using membership test algorithm, a Bloom filter.
