Diverse kind of attack using the vulnerability of user authentication on Internet service is announced recently. Especially, security accidents on the Internet banking service and Internet telephony service(SIP) are increased rapidly. Attack skills are also evolved into intelligent mechanism. Therefore, more enhanced authentication mechanism is required on existing Internet banking and telephone services for preventing those kinds of attacks using personal identity information such as biometric data. In this research, the proposed B-OTP mechanism can be used to enhance security on a user authentication procedure by combining biometric data with existing OTP mechanism. As a result, the security on internet banking and Internet telephone service will be more improved by using proposed B-OTP mechanism.

In recent years, there is growing interest in 'Fin-tech' in the domestic and international financial sector. And a variety of services in such a situation has emerged. To ensure the safety of from hacking attacks, many new technologies have been developed. These leading technology is the Bio-authentication method that you consider applying to the financial sector. Bio authentication is using biometric information. Also it is known that can cope the threat of fabrication and modifying attacks with shared and stored. However, Recently, When you look at hacking incidents of biometric data(560 million cases) in the United States Office of Personnel Management and advent of the fingerprints counterfeit technology, We can be known that should be reconsidered about the safety of bio-certification. Especially, it should be provided with a response measures for the problem of embezzlement that biometric information already been leaked. Thereby In this paper, by investigating biometric technologies and practices applied and of the vulnerability factor in many industries, it expected to be utilized in the prepared threats countermeasures in accordance with the application of the biometric authentication technology in a future.

Digital accredited certificates issued under the Digital Signature Act provide essential functionalities for online service, so certificates are used for various services such as online banking, e-government. However, certificates can be stolen by hackers and users need to install separate software to use certificates. Recently FIDO, which aims to solve the problems of password-based authentication and the lack of interoperability between authentication methods, is used for biometric authentication and TrustZone, hardware-based secure environment, is used for safe smartphone usage. In this paper, the new service method is suggested which uses FIDO-based biometric authentication and stores certificates in TrustZone. This method can not only improve security and convenience but also be easily applied to the service because it uses built-in functionalities of new smartphones such as biometric sensors and TrustZone. It is expected that people can use certificates in a safe and convenient way with this method.

Biometric technologies using biometric information like fingerprints features are in wide use for the secure user authentication in many services including log-in of computer systems, entrance ID and E-commercial security. Nowadays, biometric technologies are ported into small embedded systems like security tokens or smart cards due to the merit of being secure and automatic in comparison with the previous method in user authentication such as using a PIN. In this paper, the security token developed as an embedded system and tile user authentication system implemented and tested using fingerprints information are described. Communications between the security token and tile host are tested and verified with USB. And, execution time and runtime memory on tile security token board was measured and performance improvement was described. In addition, requisites for the transit from the security token to the match-on-card was mentioned.

With the wide deployment of biometric authentication systems, several issues pertaining security and privacy of the biometric template have gained great attention from the research community. To resolve these issues, a number of biometric template protection methods have been proposed. However, the design of a template protection method to satisfy four criteria, namely diversity, revocability and non-invertibility is still a challenging task, especially performance degradation when template protection method is employed. In this paper, we propose a novel method to generate a revocable minutiae-based fingerprint template. The proposed method consists of feature extraction from fingerprint minutiae pairs, quantization, histogram binning, binarization and eventually binary bit-string generation. The contributions of our method are two fold: alignment-free and good performance. Various experiments on FVC2004 DB1 demonstrated the effectiveness of the proposed methods.

유비쿼터스 사회는 인터넷망을 이용하여 생활에 적용되는 서비스들이 무수히 많아지고, 이를 안전하고 정확하게 서비스하기 사용자 인증이 중요한 요소로 강조되고 있다. 인터넷망 환경에서는 비대면 및 비서면의 사용자 인증이 이루어지고 있으며, 다양한 인증 요소를 통한 보안성 강화를 이루고 있다. 그 중 생체정보를 이용한 사용자 인증은 생체정보의 고유성, 불변성 등과 같은 특성으로 인해 강력한 인증 수단으로서 주목받고 있다. 그러나 이러한 강력한 인증 수단을 제공하는 고유성으로 인해 사용자 인증 수단의 변경 불가능이라는 문제점도 가지고 있다. 본 논문에서는 이와 같은 생체정보의 변경 불가 문제점을 해결하기 위하여 개인의 생체정보를 활용한 Meta-Biometric 정보를 생성하여, 사용자의 생체정보를 변경 및 재사용 할 수 있는 방안을 제안한다.

Privacy means the right not to interfere with the private life of an individual. Bio data is the most private personal information about the person itself, and according to advancement of technology, it is possible to analyze and judge individual as well as identify individual. The Personal Information Protection Act is based on global privacy principles, but the legislation for the protection of bio information has yet to be enacted. Therefore, it is time to protect biometric data as more sensitive information than general personal information. We will review the global privacy discussions for protecting biometric information and propose additional privacy principles and measures for utilization that should be defined in the biometric information protection guideline.

In this paper, we describe biometric watermarking techniques for secure user verification on the remote, multimodal biometric system employing both fingerprint and face information, and compare their effects on verification accuracy quantitatively. To hide biometric data with watermarking techniques, we first consider possible two scenarios. In the scenario 1, we use a fingerprint image as a cover work and hide facial features into it. On the contrary, we hide fingerprint features into a facial image in the Scenario 2. Based on the experimental results, we confirm that the Scenario 2 is superior to the Scenario 1 in terms of the verification accuracy of the watermarking image.

With the advance of ICT, the necessity of user authentication to verify the identity of an opponent online not face to face is increasing. The authentication, the basis of the security, is used in various fields. Because ID-based authentication has weaknesses in terms of stability and losses, two or more than two authentication tools are used in the place in which the security is important. Recently, biometric authentication rather than ID, OTP, SMS authentication has been an issue in terms of credibility and efficiency. As the fields applied to current biometric recognition technologies are increasing, the application of the biometric recognition is being used in various fields such as mobile payment system, intelligent CCTV, immigration inspection, and access control. As the biometric recognition, finger print, iris, retina, vein, and face recognition have been studied actively. This study is to inspect the current state of domestic and foreign standardization including understanding of the face recognition and the trend of technology.

Studies on the intelligent vehicles that are fused with IT and intelligent vehicle technologies are currently under active discussion. And many new service models for them are being developed. As intelligent vehicles are being actively developed, a variety of wireless services are support. As such intelligent vehicles use wireless network, they are exposed to the diverse sources of security risk. This paper aims to examine the factors to threaten intelligent vehicle, which are usually intruded through network system and propose the security solution using biometric authentication technique. The proposed security system employs biometric authentication technique model that can distinguish the physical characteristics of user.
