An identity authentication device combining digital signature, handwriting and fingerprint

Abstract

The invention relates to an identity authentication device and method with a digital signature, handwriting and a fingerprint combined. The identity authentication device with the digital signature, the handwriting and the fingerprint combined comprises a main control module, a fingerprint module and a handwriting module, wherein the main control module is connected with a PC, or an external connecting disk, or a mobile terminal via a USB / a serial port / a wired network / a WIFI external data interface, the handwriting module is used for adding a handwriting signature to a relevant position of an electronic document under the condition that a user needs to carry out a traditional signature on the electronic document, the fingerprint module is used for obtaining a fingerprint image and delivering the fingerprint image to the main control module, the main control module will carry out identity authentication based on the fingerprint image and add the fingerprint to a relevant position of the document, and the main control module is used for providing an encryption and decryption algorithm and a fingerprint algorithm, main logical processing, external control and communication data processing. The identity authentication device with the digital signature, the handwriting and the fingerprint combined has the advantages that a traditional signature mode can be achieved in the paperless office environment, usage habits of a user are changed as few as possible, the application reliability is higher than that achieved by only usage of a PKI system, and the problems that the traditional paper signature is prone to damage, difficult to inquire, and high in saving cost are solved.

Description

technical field [0001] The invention relates to the field of identity authentication, more specifically, it relates to an identity authentication device and method combining digital signature, handwriting and fingerprint. Background technique [0002] In the process of paperless office promotion, the traditional paper signature mode has become more and more obvious to the problems of high resource consumption, difficult management, and fragility. Or it is not very suitable for applications such as joint announcements. [0003] In current applications, the traditional paper signature mode is the most common, the main process is as follows, such as figure 1 Shown: [0004] 1. The relevant superior supervisor drafts the document, and after the discussion is passed, the document is signed and approved, and issued for execution; [0005] 2. File the originals or copies of the signed documents in a unified manner and be managed by the management department (or the departments a...

Problems solved by technology

[0026] The purpose of the present invention is to overcome the deficiencies in the prior art, and provide an identity authentication device and method combining digital signatures, handwriting and fingerprints. The present invention solves the problems of fragile paper signatures, difficult inquiries and large storage costs, and It solves the problem that the paper signature mode is difficult to integrate with the paperless office, and at the same time strengthens some inappropriate areas of the PKI system in practical applications
