Abstract
The present invention provides a kind of electronic signature method, computer readable storage medium and computing devices.The electronic signature method, including：Obtain file；Identity based on user reads the Electronic Signature of the user；And the file for merging and having the Electronic Signature is generated based on the file and the Electronic Signature of the user.Some embodiments through the invention can avoid Electronic Signature resolved.
Description
Technical field
The present invention relates to a kind of electronic signature method, computer readable storage medium and computing devices.
Background technology
With universal, the various e-commerce initiative and the movable rapid development of E-Government of Internet, Electronic Signature
Start to be widely applied among every field, includes mainly：Send safety E-mail, access safety website, Internet-based tendering
Bid, sign up agreement on Internet, shopping on net, safe Document-Intranet, Online Payment, pay taxes on the net, online stock trading, shopping online and
Online declaration etc..
Electronic Signature is intended for a kind of means of authentication, refers to institute as digital certificate used in everyday
Have and electronically exist, be attached to electronic document and with its logic association, can be used to recognize electronic document signatory's identity, protect
The integrality of file is demonstrate,proved, and indicates the content that signatory agrees to that electronic document is stated the fact.
It has been able to convert Electronic Signature to using image processing techniques at present identical with paper document stamping
Visual effect, while utilizing the authenticity and integrity of Electronic Signature technical guarantee electronic document.
However, current Electronic Signature technology cannot still meet user demand in terms of safety.For example, for common
The mode of Electronic Signature picture is inserted into electronic document, there are the resolved out risks of Misuse of Electronic Signature.
Invention content
The some embodiments of the present invention at least one technical problem to be solved is deficiency for the above-mentioned prior art,
A kind of electronic signature method, computer readable storage medium and computing device that can solve above-mentioned technical problem is provided.
In some embodiments, a kind of electronic signature method is provided, including：Obtain file；Identity based on user
Read the Electronic Signature of the user；And had based on the file and the generation fusion of the Electronic Signature of the user described
The file of Electronic Signature.
In some embodiments, the Electronic Signature of the user includes stamped signature figure layer, and described based on described
File and the Electronic Signature of the user, which generate fusion, has the file of the Electronic Signature to include：By the stamped signature figure layer and
The figure layer of the file permeates figure layer.
In some embodiments, the Electronic Signature of the user further comprises identifying figure layer, the mark figure
Layer has predefined size and predetermined pattern.
In some embodiments, the predetermined pattern includes one or more of the following terms：Prespecified geometric,
Predetermined image and predetermined word.
In some embodiments, the predetermined pattern has directive pattern.
In some embodiments, the predetermined pattern and the predefined size have scheduled mapping relations.
In some embodiments, the Electronic Signature includes one or more of the following terms：E-seal pattern,
Idiograph, anti-counterfeiting information and user information.
In some embodiments, the file figure layer is obtained from DWG documents.
In some embodiments, a kind of computer readable storage medium being stored with computer program is provided, it is described
Computer program is when being executed by processor for realizing the electronic signature method according to any aforementioned embodiments.
In some embodiments, it provides a kind of computing device, including memory, processor and is stored in described deposit
Computer program on reservoir, the computer program is when being executed by processor for realizing according to any aforementioned embodiments
The electronic signature method.
At least one advantageous effect of some embodiments of the present invention is：Electronic Signature can be avoided resolved.
The invention content of front is only illustrative, and it is restrictive in any way to be not intended to.Except the above
Illustrative aspect, except embodiment and feature, aspect, embodiment and feature in addition by referring to accompanying drawing and it is following in detail
Thin description will become obvious.
Description of the drawings
According to the following description and appended claims in conjunction with attached drawing, above-mentioned and other feature of the invention will become more
Add clear.Understand that these attached drawings only describe according to certain embodiments of the present invention, to be not considered as the limitation present invention's
Range will describe the present invention by using attached drawing more features and details.
Fig. 1 is the flow chart of electronic signature method provided by the present invention.
Specific implementation mode
It is described further in conjunction with attached drawing.
Fig. 1 shows the flow chart of electronic signature method provided by the present invention.With reference to attached drawing 1, the present invention is in some realities
It applies in mode, provides a kind of electronic signature method, including：S101：Obtain file；S102：Identity based on user, which is read, to be used
The Electronic Signature at family；And S103：Generating fusion based on file and the Electronic Signature of user has the file of Electronic Signature.Passing through will
The file of pending Electronic Signature is merged with Electronic Signature, can avoid Electronic Signature resolved to a certain extent.This
In used term " fusion " refer to file and Electronic Signature being associated.To be led due to the associated presence
Electronic Signature is caused not parsed easily.
In some embodiments, the Electronic Signature of user includes stamped signature figure layer, and the electronics based on file and user
Stamped signature, which generates fusion, has the file of Electronic Signature to include：The figure layer of stamped signature figure layer and file is permeated figure layer.Namely
It says, in some embodiments, being associated with for file and Electronic Signature is exactly that the figure layer of stamped signature figure layer and file permeates a figure
Layer, so that Electronic Signature cannot be separated from the figure layer after fusion.
In addition, in some embodiments, file can also be with being associated with for Electronic Signature in Electronic Signature and file
Partial character or pattern overlapping, by overlapping so that Electronic Signature is difficult to be resolved.Here overlapping can be partly overlapped.
In some embodiments, the Electronic Signature of user further comprises identifying figure layer, and mark figure layer has predetermined big
Small and predetermined pattern.By increasing mark figure layer in Electronic Signature, due to the mark figure with predefined size and predetermined pattern
The presence of layer, even if the stamped signature figure layer of Electronic Signature is resolved only to rely on can not pass through legitimacy if the stamped signature figure layer being resolved to
Verification.In some embodiments, predetermined pattern includes one or more of the following terms：Prespecified geometric, predetermined figure
Picture and predetermined word.For example, prespecified geometric may include star, polygon.For example, predetermined image may include various anti-
Pseudo- image.In some embodiments, predetermined pattern has directive pattern.For example, can be based on the direction of predetermined pattern
Property come to mark figure layer be configured, if directionality changes, Electronic Signature may be tampered.In some embodiments
In, predetermined pattern and predefined size have scheduled mapping relations.If the mapping relations of predetermined pattern and predefined size occur
Variation, then Electronic Signature may be tampered.
In some embodiments, Electronic Signature includes one or more of the following terms：E-seal pattern, individual
Signature, anti-counterfeiting information and user information.
In some embodiments, file figure layer is obtained from DWG documents.It is a kind of figure that AutoCAD is founded from DWG documents
Paper preserves format, has become the reference format of D CAD, and a lot of other CAD also directly use DWG to be compatible with AutoCAD
As acquiescence working document.
