Mobile device access control: an improved correlation based face authentication scheme and its Java ME application

Abstract

SUMMARY This paper investigates face authentication based access control solutions for camera‐equipped mobile devices. A new hierarchical correlation based face authentication (HCFA) scheme is proposed, which suits resource‐constrained mobile devices such as mobile phones and personal digital assistants. The idea of HCFA is conducting a partial correlation output peak analysis (analyze the relationship between each cross‐correlation output peak generated from selected sub‐regions of a face), in conjunction with conventional direct cross‐correlation methods. The experimental results on the public domain database demonstrate that the proposed scheme achieved better performance than that of the conventional direct correlation based schemes. Furthermore, HCFA was implemented on the Nokia S60 CLDC emulator using Java ME (previously J2ME) programming technology in order to test the applicability and implementability. The test results show that the proposed algorithm is implementable on mobile devices. It not only shortens processing time but also reduces resource demand significantly, compared with the direct correlation algorithms. Copyright © 2011 John Wiley & Sons, Ltd.

Double layer secure sketch

“…Indeed, longer human-generated passwords (answers to a series of questions, pass-phrases) can achieve higher level of security, but it is hard for people to memorize longer passwords precisely [14]. Although biometrics security is promising in addressing this issue [15] [16] [17] [18] [19] [20][21] [22][23] [24] [26], biometric readings may vary from time to time due to noise [24]]25] [26], feature extraction errors [15] [16], rotation [24] and so forth. Consequently, it is necessary for the system to be error-tolerated.…”

“…In addition, suppose 2 W is uniformly distributed, we can get 16 r as large as possible and ensure the security. About entropy loss and remaining entropy of fuzzy vault, please refer to Appendix D in [14].…”

A cancellable and fuzzy fingerprint scheme for mobile computing security

“…An unauthorized person can gain access to a wealth of information stored on these devices or access to other services via them. So the authentication of the device or its user to the net bank, government system, or other applications is needed [1] [2].…”
