Abstract
The invention discloses a remote online electronic signature method based on WEB script data stream operation, which relates to the field of electronic signature, in particular to a method for realizing the function of online electronic signature under the condition of no Ukey.
Description
Technical Field
The invention relates to the field of electronic signatures, in particular to an application system which realizes the function of online electronic signatures without Ukey and completes the electronic signatures by adopting the assistance of a mobile client held by a signer and a remote server provided by the system.
Background
The electronic signature is an important scene of electronic signature service, and by combining the traditional seal pattern with the electronic signature, the electronic seal can be vividly embodied while a signature value is added to an electronic document, so that the habit continuation of the traditional paper seal is realized; the common electronic signature is usually completed by filling a pattern of a seal in a Ukey, inserting the Ukey into a computer when electronic signature is required to be performed on a target file, and locally running a signed control program.
However, the Ukey has the defects of insufficient convenience in use, high use threshold and insufficient support for intelligent mobile terminals such as mobile phones and the like in the existing mobile internet environment, so that how to realize reliable electronic signature becomes a problem under the condition of no Ukey;
meanwhile, with the development of internet commerce, more and more economic behaviors are directly generated on line, files needing to be signed in many scenes cannot be downloaded to the local computer, but are directly circulated in a WEB browser, and for the signing scenes of the files which are not in the local computer, a Ukey mode is difficult to support, so that an implementation method for supporting on-line signing is needed.
