ID-based authentication scheme combined with identity-based encryption with fingerprint hashing

The Journal of China Universities of Posts and Telecommunications 2008年第4期15卷 75-80,120页

作者： JIANG Wei-qiang HUANG Zheng-quan YANG Yi-xian TIAN Jie LI Liang Information Security Center State Key Laboratory of Networking and Switching Technology Beijing University of Posts and Telecommunications Beijing 100876 China Key Laboratory of Complex Systems and Intelligence Science Institute of Automation Chinese Academy of Sciences Beijing 100080 China

Current identity-based （ID） cryptosystem lacks the mechanisms of two-party authentication and user＇s private key distribution. Some ID-based signcryption schemes and ID-based authenticated key agreement protocols have been presented, but they cannot solve the problem completely. A novel ID-based authentication scheme based on ID-based encrypfion （IBE） and fingerprint hashing method is proposed to solve the difficulties in the IBE scheme, which includes message receiver authenticating the sender, the trusted authority （TA） authenticating the users and transmitting the private key to them. Furthermore, the scheme extends the application of fingerprint authentication from terminal to network and protects against fingerprint data fabrication. The fingerprint authentication method consists of two factors. This method combines a token key, for example, the USB key, with the user＇s fingerprint hash by mixing a pseudo-random number with the fingerprint feature. The security and experimental efficiency meet the requirements of practical applications.

Fingerprint-Based Identity Authentication and Digital Media Protection in Network Environment

Journal of Computer science & Technology 2006年第5期21卷 861-870页

Current information security techniques based on cryptography are facing a challenge of lacking the exact connection between cryptographic key and legitimate users. Biometrics, which refers to distinctive physiological and behavioral characteristics of human beings, is a more reliable indicator of identity than traditional authentication system such as passwords-based or tokens-based. However, researches on the seamless integration biometric technologies, e.g., fingerprint recognition, with cryptosystem have not been conducted until recent years. In this paper, we provide an overview of recent advancements in fingerprint recognition algorithm with a special focus on the enhancement of low-quality fingerprints and the matching of the distorted fingerprint images, and discuss two representative methods of key release and key generation scheme based on fingerprints. We also propose two solutions for the application in identity authentication without trustworthy thirdparty in the network environment, and application in digital media protection, aiming to assure the secrecy of fingerprint template and fingerprint-based user authentication.

Use of colour and shape constraints in vision-based valve operation by robot

引用

International Journal of Advanced Robotic systems 2006年第3期3卷 267-274页

作者： Xu, De Tan, Min Jiang, Zemin Hu, Osheng Key Laboratory of Complex Systems and Intelligence Science Institute of Automation Chinese Academy of Sciences Beijing 100080 China Department of Computer Science University of Essex Colchester CO4 3SQ United Kingdom

This paper proposes a new strategy for a humanoid robot to approach and operate a valve based on colour and shape constraints. It consists of four stages, namely rough base approaching, fine base approaching, rough hand approaching and fine hand approaching and grasping. The robot estimates the object's position using its stereo-vision at the first stage. A new visual positioning method is used to determine the valve's position and pose in the robot's frame in the second stage. When its hands are near the valve, a visual servoing method is employed to catch the handle of the valve via cameras in end-effectors. The advantages of both eye-in-head and eye-to-hand systems are exploited. Experimental results are presented to verify the effectiveness of the proposed method.

A fingerprint identification algorithm by clustering similarity

This paper introduces a fingerprint identification algorithm by clustering similarity with the view to overcome the dilemmas encountered in fingerprint identification. To decrease multi-spectrum noises in a fingerprint, we first use a dyadic scale space (DSS) method for image enhancement. The second step describes the relative features among minutiae by building a minutia-simplex which contains a pair of minutiae and their local associated ridge information, with its transformation-variant and invariant relative features applied for comprehensive similarity measurement and for parameter estimation respectively. The clustering method is employed to estimate the transformation space. Finally, multi-resolution technique is used to find an optimal transformation model for getting the maximal mutual information between the input and the template features. The experimental results including the performance evaluation by the 2nd International Verification Competition in 2002 (FVC2002), over the four fingerprint databases of FVC2002 indicate that our method is promising in an automatic fingerprint identification system (AFIS).

In this paper, a class of continuous-time nonlinear multi-person zero-sum differential game problems is solved using an iterative adaptive dynamic programming (ADP) method. The idea is to use ADP technique to obtain the optimal control pair iteratively which makes the performance index function reach the saddle point of the zero-sum differential games, which does not require to check the existence of saddle point in advance. It can be proved that the optimal control pair can make the performance index function reach the optimum. Stability analysis of the nonlinear systems is presented and the convergence property of the performance index function is also proved. A simulation example is given to illustrate the performance of the present method. © 2011 Chinese Assoc of Automati.

This paper deals with the finite-horizon optimal tracking control for a class of discrete-time nonlinear systems using the iterative adaptive dynamic programming (ADP) algorithm. First, the optimal tracking problem is converted into designing a finite-horizon optimal regulator for the tracking error dynamics. Then, with convergence analysis in terms of cost function and control law, the iterative ADP algorithm via heuristic dynamic programming (HDP) technique is introduced to obtain the finite-horizon optimal tracking controller which makes the cost function close to its optimal value within an e-error bound. Moreover, three neural networks are used to implement the algorithm, which aims at approximating the cost function, the control law, and the error dynamics, respectively. At last, an example is included to demonstrate the effectiveness of the proposed approach. © 2011 Chinese Assoc of Automati.
