Abstract

The invention discloses an electronic document signature protecting method which comprises the following steps of: acquiring handwriting information of a signer; encrypting the digital summary of a document to be signed by utilizing at least one key for signing to acquire an encryption result, wherein the signed document comprises an original document; and generating a signature compound document which comprises handwriting information, the signed document and the encryption result. The invention also discloses an electronic document signature protecting system. Under the condition that special preset processes (manufacture and confirmation processes) are not needed, the method and the system can be used for confirming the safety of the document and are visual and convenient.

Description

technical field [0001] The invention relates to electronic signature technology, in particular to an electronic document signature protection method and system. Background technique [0002] With the development of science and technology, electronic signature technology has been widely used. Electronic signature technology can ensure that documents cannot be tampered with, but electronic signature technology is invisible and intangible, and it is not intuitive to use, nor does it conform to general usage habits and experience, so electronic seal technology has gradually emerged. [0003] Electronic seal is the application and manifestation of electronic signature, if and only when electronic signature technology is used to verify the authenticity and validity of an electronic document, the electronic seal can be displayed / printed normally. Electronic seal technology uses advanced digital technology to simulate traditional physical seals, turning invisible and intangible ele...
