Practical Digital Signature Generation Using Biometrics
نویسندگان
چکیده
It is desirable to generate a digital signature using biometrics but not practicable because of its inaccurate measuring and potential hill-climbing attacks, without using specific hardware devices that hold signature keys or biometric templates securely. We study a simple practical method for biometrics based digital signature generation without such restriction, by exploiting the existing tools in software in our proposed model where a general digital signature such as RSA can be applied without losing its security.

Biometric Digital Signature Key Generation and Cryptography Communication Based on Fingerprint
A digital signature is a term used to describe a data string which associates a digital message with an assigned person only. Therefore, the main goal (or contribution) of this work is to study a simple method for generating digital signatures and cryptography communication using biometrics. The digital signature should be generated in the way that it can be verified by the existing cryptograph...
متن کاملDigital Signature Generation using Fingerprint, Password and Smart Card
In a digital signature scheme, the security of the private key is of vital importance. If the private key is ever compromised, it can be used to sign forge documents. The conventional method of secure private key storage is through password-based encryption. However, user-chosen passwords have very low entropy, which may be exploited by an attacker to launch password-guessing attacks. In order ...

It is desirable to generate a digital signature using biometrics but not practicable because of its inaccurate measuring and complex methodologies, without using specific hardware devices that hold signature keys or biometric templates securely. Proposed model resolves the problem in biometric based digital signature by making it simple and secure. Proposed model uses the biometric template and...
متن کاملA Novel Patch-Based Digital Signature
In this paper a new patch-based digital signature (DS) is proposed. The proposed approach similar to steganography methods hides the secure message in a host image. However, it uses a patch-based key to encode/decode the data like cryptography approaches. Both the host image and key patches are randomly initialized. The proposed approach consists of encoding and decoding algorithms. The encodin...
متن کاملA Biometric Based E-security System for Internet-based Applications
-Personal identification numbers (PIN), passwords, smart cards and digital certificates are some of the means employed for user authentication in various electronic commerce applications. However, these means do not really identify a person, but only knowledge of some data or belonging of some determined object. This paper introduces the notion of Biometric Signature: a new approach to integrat...
