Abstract

The invention discloses an electronic document countersigning method comprising the steps of identifying biological feature information and a personal digital certificate of a current user; generating a multi-feature composite key based on the biological feature information and the personal digital certificate of the user; extracting a key element included by a preset personal countersigning key and storing the element into a countersigning key group; judging whether the countersigning key group includes all key elements of the countersigning key group; if yes, sending a notice of allowing for countersigning; and otherwise, waiting for the next user to input the information, and repeating the above steps to the next user. The invention also discloses an electronic document countersigning device, and an electronic identity pen.

Description

technical field [0001] The invention relates to the field of digital information transmission, in particular to an electronic document countersign method, device and electronic identity pen. Background technique [0002] In a highly informationized environment, information security is particularly important, and due to the popularization of computer equipment and networks, e-commerce and e-government affairs are becoming more and more developed, paperless office has been vigorously promoted, and many electronic documents are often lost due to their confidentiality and other reasons. Authentication of the viewer is required to decrypt. The current mainstream verification methods include traditional seal or handwritten signature, digital signature technology (PKI) and fingerprint or iris recognition. [0003] The traditional seal or handwritten signature mode is difficult to avoid the problem of forging seals and imitating handwriting. Paper materials consume more resources a...
