오늘날 바이오 정보처리 소프트웨어의 품질은 각종 보안장치의 성능과 신뢰성을 좌우하는 중요한 요소로 자리잡고 있다. 국내의 경우, 아직 바이오 정보처리 소프트웨어에 대한 품질특성, 특히 신뢰성에 관한 품질평가와 인증이 자리잡지 못한 실정이며 평가와 인증을 위한 시험 인증체계가 구축되어 있지 않은 실정이다. 이로 인해, 바이오 정보처리 소프트웨어의 품질저하로 인한 생체인식 분야의 보안성 및 신뢰성 저하를 유발할 수 있는 문제점이 발생할 수 있다. 본 연구에서는 ISO/IEC 12119와 ISO/IEC 9126을 기반으로 바이오 정보처리 소프트웨어의 품질요구를 체계화하고 신뢰성 중심의 바이오 정보처리 소프트웨어 시험모듈과 시험모듈 적용을 위한 점검표를 구축하였다.

In the case of the password-based PKI technology, because it protects by using the password which is easy that user memorizes the private key, he has the problem about the password exposure. In addition, in the system of electronic bidding, the illegal use using the authentic certificate of the others increases. Recently, in order to solve this problem, the research about the PKI technology using the biometrics is actively progressed. If the bio information which the user inputs for the bio authentication is converted to the template, the digest access authentication in which the security is strengthened than the existing authentication technology can be built. Therefore, in this paper, we had designed and developed the system of electronic bidding which it uses the most widely used fingerprint information in the biometrics, it stores the user fingerprint information and certificate in the fingerprint security token and can authenticate the user. In case of using the system of electronic bidding of the public key infrastructure using the fingerprint information proposed in this paper the agent bid problem that it uses the certificate of the others in not only user authentication intensification but also system of electronic bidding can be concluded.

With the recent development and increasing importance of personal identification systems, biometric technologies with less risk of loss or unauthorized use are being popularized rapidly. In particular, because of their high identification rate and convenience, fingerprint identification systems are being used much more commonly than other biometric systems such as iris recognition, face recognition and vein pattern recognition. However, a fingerprint identification system has the problem that artificially forged finger-prints can be used as input data. Thus, in order to solve this problem, the present study proposed a method for detecting forged fingerprints by measuring the degree of attenuation when the light from an optical fingerprint sensor passes through the finger and analyzing changes in the transmission of light over stages at fixed intervals. In order to prove improvement in the performance of the proposed system, we conducted an experiment that compared the system with an existing multi-sensor recognition system that measures also the temperature of fingerprint. According to the results of the experiment, the proposed system improved the forged fingerprint detection rate by around 32.6% and this suggests the possibility of solving the security problem in fingerprint identification systems.

We have addressed two important issues of immunosensing biochips, including the construction of antibody functionalized suface for efficient affinity reactions and the development of a signal registration strategy that converts biospecific reactions into highly quantifiable electrochemical and/or optical signals. The developed immunoassay reaction is an integrated version of enzyme-mediated immunoprecipitaion reaction, which is widely used in immunohistochemistry, and electrochemical signaling reaction. For the evaluation of analytical performance of fabricated immunosensing biochips, signaling for mouse IgG in antiserum was conducted. Applications of the developed strategy have been found for the evaluation of histology chemicals and for the signal amplification for array-type biochip analysis.

With mobile-epoch and emerging of Fin-tech, Bio-recognition technology utilizing bio-information in secure method has spread. Specially, In order to change convenient payment services and transportation cards, the combination of biometrics and mobile services are being expanded. The basic concept of authentication such as access control, IA&A, OpenID, OAuth 1.0a, SSO, and Biometrics techniques are investigated, and the protocol stack for security API platform, FIDO, SCIM, OAuth 2.0, JSON Identity Suite, Keystone of OpenStack, Cloud-based SSO, and AIM Agent are described detailed in aspect of application of AIM. The authentication technology in domestic and foreign will accelerate technology development and research of standardization centered in the federated FIDO Universal Authentication Framework(UAF) and Universal 2 Factor Framework(U2F). To accommodate the changing needs of the social computing paradigm recently in this paper, the trends of various authentication technology, and design and function of AIM framework was defined.

As small sized bio-sensors and digital yarns are developed, digital wear measuring vital signs can be used for individuals' health, the elderly care and sports activities. This paper discusses a database structure for analyzing stress state, pulses, positions, exercise amount of user based on vital signs measured for 24 hours measured by the wear and GPS information, and a storage for storing XML documents following a standard HL7 meta-model. By analyzing the stored information, the system identifies the stress state and exercise amount of users. Pulses, exercise intensity and emergency situations can be also detected by the system in real time. This paper discusses the implementation of a system enabling to acquire and analyze vital signals to understand user behavior patterns.

In the era of the 4th industrial revolution, airports around the world are rapidly pushing for smart airports. One ID service based on biometric technology to eliminate congestion and improve airport operation efficiency is one of them. In particular, biopass, which allows you to use the entire journey with one single token without an ID card or boarding pass from arrival at the airport to boarding an aircraft, is emerging as an important technology for smart airports. This study conducted an empirical analysis to identify factors that affect the intention to use in two aspects: the acceptance, and rejection of bio-pass by combining UTAUT and the innovative resistance model. As a result of the study, it was found that the relative advantages and compatibility had a positive effect on the intention to use, and the perceived risk had a negative effect on the intention to use through innovation resistance. This suggests that infrastructure expansion and usage expansion are needed to use time more efficiently at airports, and that the government, airlines, and airport operators need to cooperate to strengthen the security system to relieve users' psychological anxiety.
