Method of Two-Factor Authentication of Electronic Documents Using Enhanced Encrypted Non-Certified Digital Signature with the Use of Security Token with Biometric Data

Abstract

The purpose of this study is to develop a method for two-factor authentication of electronic documents using an enhanced encrypted non-certified digital signature with the use of a security token with biometric data (fingerprint image). In order to achieve the goal, the method of comparative analysis was used. Existing algorithms for the electronic signature operation were studied. The method of multi-factor authentication of an electronic signature using biometric data has been studied in detail. Biometric data included: a handwritten password, an autograph, typing biometrics when typing a pass phrase, a facial image, typing biometrics when typing a free text. An external storage medium with a biometric authentication method based on a fingerprint image was also studied. Information on this media was accessed by scanning a fingerprint image. After conducting a comparative analysis and studying in detail these methods, a method for two-factor authentication of an electronic signature using a security token with biometric data was developed.
