Tamper-Resistant Biometric IDs

چکیده
We present FaceCerts, a simple, inexpensive, and cryptographically secure identity certification system. A FaceCert is a printout of person’s portrait photo, an arbitrary textual message, and a 2-D color barcode which encodes an RSA signature of the message hash and the compressed representation of the face encompassed by the photo. The signature is created using the private key of the party issuing the ID. ID verification is performed by a simple off-line scanning device that contains the public key of the issuer. The system does not require smart cards; it can be expanded to encompass other biometric features, and more interestingly, the ID does not need to be printed by a trusted or high-end printer, it can be printed anywhere, anytime, and potentially by anyone. The ID verifier uses a single scan process which does not require the use of displays. We detail system’s components and present a preliminary performance evaluation using an in-field experiment.

Summary of Nist Standards for Biometric Accuracy, Tamper Resistance, and Interoperability
This appendix briefly outlines appropriate standards for biometric accuracy, tamper resistance, and interoperability based on current findings and test results. Due to the time constraints imposed by the Patriot and Enhanced Border Security acts, biometrics to be initially tested and certified by NIST as being highly accurate must conform to certain conditions. First, any biometric to be consid...
متن کاملTamper-proof and Privacy-protected Fingerprint Identification Systems
In this paper alternatives of tamper-proof and privacy-protected biometric identification systems are shown. One approach to secure such databases is to use cryptography. With its help it is possible to highly protect a system from any external attacker but an internal attacker still has direct access to all stored biometric data. This risk shall be avoided by using biometric encryption with an...
متن کاملCombining cryptography with biometrics effectively
We propose the first practical and secure way to integrate the iris biometric into cryptographic applications. A repeatable binary string, which we call a biometric key, is generated reliably from genuine iris codes. A well-known difficulty has been how to cope with the 10 to 20% of error bits within an iris code and derive an errorfree key. To solve this problem, we carefully studied the error...
متن کاملSecuring the Process of Insurance Application
Abstract— Legislation in many countries treats electronic signatures similar to autographic ones. Completely electronic processes thereby are theoretically possible but customers today have neither knowledge nor means to issue electronic signatures. This study describes a process that will produce some reliable signature without the need of preparation on side of the customer. As an example the...
متن کاملBiometric Template Security
Biometric recognition offers a reliable solution to the problem of user authentication in identity management systems. With the widespread deployment of biometric systems in various applications, there are increasing concerns about the security and privacy of biometric technology. Public acceptance of biometrics technology will depend on the ability of system designers to demonstrate that these...
