Description
Technical Field
The invention relates to the technical field of electronic signatures, in particular to a multiple anti-counterfeiting electronic signature method.
Background
It is often the case that an electronic signature is provided during operation because the signatory is unable to personally sign his/her signature. For example: the people can not gather in the epidemic situation and can not personally sign on the scene. Because the epidemic situation can only be answered on the internet, the signature of the experts can not be on site, and the electronic signature also needs to be provided.
Currently, if the electronic signature of the user is issued to another person in a trade, the other person may use the electronic signature indefinitely for many times without authorization of the other person, so that the current electronic signature has the defects of reproducibility, no anti-counterfeiting, no authorization, poor safety and the like, and the situations of property loss, illegal crime and the like can be caused in some important occasions; referring to fig. 1, fig. 1 shows a signature effect without anti-counterfeit effect in the prior art.

Aiming at the defects in the prior art, the invention provides a multiple anti-counterfeiting electronic signature method to overcome the defects of reproducibility, no anti-counterfeiting, no authorization, poor safety and the like of the current electronic signature.
In order to achieve the purpose, the invention adopts the following technical scheme:
a multiple anti-counterfeiting electronic signature method comprises the following steps:
s1: setting the size of the signature area according to the requirement of a user or setting the size of the signature area by default under the condition that the size is not set by the user;
s2: performing anti-counterfeiting treatment on the signature area according to the size of the signature area to improve the safety, wherein the anti-counterfeiting treatment comprises shading anti-counterfeiting treatment and signature anti-counterfeiting treatment;
s3: writing a self signature on the signature area by a user, and finishing the signature by improving the color depth of the strokes of the signature and the contrast of the signature;
s4: generating a two-dimensional code or a bar code from the content information on the signature area, placing the two-dimensional code or the bar code on the signature area, and carrying out safety processing on the two-dimensional code or the bar code;
s5: and storing the content information on the signature area to the local and uploading the content information to a cloud server.
In order to optimize the technical scheme, the specific measures adopted further comprise:
further, the details of the fingerprint anti-counterfeiting processing in step S2 are as follows:
selecting a picture designated by a user or randomly selecting a picture to be inserted into the signature area in the database, and finally determining the shading image by randomly selecting a certain area in the picture or selecting a certain area in the picture by the user through the operations of amplifying the picture, reducing the picture and moving the picture to finally determine the shading image;
and processing the shading image, wherein the processing content comprises the steps of improving the brightness of the shading image and reducing the contrast of the shading image.
Further, the picture selected by the user designation in the database or the picture selected at random is a picture of a non-single color combination.
Further, the specific content of the signature anti-counterfeiting processing in step S2 is as follows:
a user writes anti-counterfeiting information characters on the shading image by hand, wherein the content of the anti-counterfeiting information characters comprises the purpose for signing and the time for signing;
and processing the anti-counterfeiting information characters, wherein the processed content comprises the reduction of the color depth of the strokes of the anti-counterfeiting information characters.
Further, the specific content of the anti-counterfeiting processing performed on the two-dimensional code or the barcode in step S4 is as follows:
and taking the position image of the signature area where the current two-dimensional code or bar code is as the background color of the two-dimensional code or bar code.
The invention has the beneficial effects that:
1. the image is inserted to set the shading anti-counterfeiting (shading image) so as to effectively prevent bad personnel from tampering with the signature anti-counterfeiting information through photo shop and other image editing software, and the shading image (the image with non-single color is set so as to prevent tampering) also can prevent the bad personnel from modifying the identifier (two-dimensional code or bar code).
2. A picture is randomly inserted as a shading, and the position of the picture displayed in the signature area can also be randomly selected. Because the picture selection has randomness and the picture display area also has randomness, the picture is used as a signature shading to achieve double anti-counterfeiting. Further, the effect of three-layer anti-counterfeiting treatment can be realized by setting signature anti-counterfeiting treatment.
3. By adding identification (two-dimensional codes or bar codes) information, personnel can conveniently obtain the signature information through scanning and compare the signature information with signature information stored in a cloud server, and the authenticity of the signature is further verified. The two-dimensional code takes a picture (shading image) inserted previously as a bottom plate, so that the two-dimensional code can be prevented from being manually tampered at the later stage, the handwriting color of the two-dimensional code is set to be darker, and the visual effect and the readability of the two-dimensional code are improved.
4. The endless reuse of the electronic signature can be effectively restrained by setting the anti-counterfeiting information of the shading anti-counterfeiting treatment and the signature anti-counterfeiting treatment.
5. Compared with the signature handwriting, the signature handwriting has deeper color setting, so that the visual effect is improved; the inserted picture is adjusted to be dim, so that the final signature effect is prevented from being influenced visually; the written anti-counterfeiting information characters are also set to be darker or lighter in color adjustment, so that the final signature effect is prevented from being influenced visually; there are many ways to set the shading and color tone, such as increasing the brightness or decreasing the contrast of the picture, or setting the picture as a gray-scale image or setting the picture as an erosion image, etc., including but not limited to these methods, and the final effect is to make it darker.

Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings.
The overall working principle adopted by the invention is as follows: the signature has anti-counterfeiting property by adding the shading (shading image) and the anti-counterfeiting information (anti-counterfeiting information characters); the specific embodiment is as follows:
step 1: the size of the signature area is set. As shown in fig. 4, the size of the signature area is set in the set size area, and if the size is not set, the system sets the size to a default value such as: length 3cm and width 1 cm. The default value may be set in the system in advance by clicking a system setting button.
Step 2: and setting the shading anti-counterfeiting (shading anti-counterfeiting treatment). The method is realized by clicking an insert picture button to insert a picture as a shading of a signature, the picture can be prepared in advance by a signer, if the picture is not prepared, the system randomly selects a picture as the signature shading, after the picture is inserted, a certain area in the picture is randomly displayed in a display preview area (signature area) or all the pictures are displayed (the display mode can be set in the system in advance by clicking a system setting button), and if the certain area is not satisfied, the picture can be slid by hands or the picture display area is amplified until the certain area is satisfied, and finally the shading image is determined. In order to prevent the contrast or chromaticity of the inserted picture from being too high to affect the final signature effect, the system will automatically increase the brightness of the inserted picture and reduce the contrast (the display mode can be set in the system in advance by clicking the system setting button), that is: the picture will automatically become dimmer and prevent visually affecting the final signature effect, as shown in fig. 5.
Because the picture selection has randomness and the picture display area also has randomness, the picture is used as a signature shading to achieve double anti-counterfeiting.
And 3, step 3: signature items and time anti-counterfeiting (signature anti-counterfeiting processing) are set. In order to further improve the anti-counterfeiting performance, the invention also makes signature items and time anti-counterfeiting performance. The specific implementation method comprises the following steps: after the shading anti-counterfeiting is set in the step 2, a part or all of the selected pictures are displayed dimly in the display preview area, and at the moment, the anti-counterfeiting information is clicked and written to carry out handwriting anti-counterfeiting information, such as: "used only for the xx item 2021.01.01 signature" and the like. The anti-counterfeiting information can be handwritten, anti-counterfeiting characters can be directly input in the system, and the handwriting has an anti-counterfeiting function. After the signature items and the time anti-counterfeiting are written, the system automatically sets the anti-counterfeiting information into a watermark effect (a system setting button can be clicked and set in the system in advance), namely: the strokes may become dimmer and prevent visually affecting the final signature effect, as shown in fig. 6. The software can be developed into various types respectively, and different types can run on different devices. The handwriting function can be implemented on a device with a touch screen, a touch pad, a writing board and the like, such as a mobile phone, a tablet computer, a computer with a writing board and the like. The recall button may also be clicked to recall the just action rewrite if the information needs to be modified.
And 4, step 4: and writing the signature. After the previous anti-counterfeiting preparation work is finished, a signature can be written next. As shown in fig. 7 or fig. 2, the name of itself is written on the display preview area. For example: "Zhang III". The default of the system is to deepen the strokes for writing the signature, and the default is black (a system setting button can be clicked and set in the system in advance), so that the strokes are more obvious on shading and anti-counterfeiting information, the contrast is higher, and the visibility is better. The revocation button can also be clicked to revoke the just action rewrite if needed to modify the signature.
And 5, step 5: a two-dimensional code is generated as shown in fig. 3. And forming a signature picture by all the anti-counterfeiting and signature information in the previous 4 steps, archiving the signature picture on a cloud server, simultaneously generating a two-dimensional code or a bar code, and displaying the two-dimensional code or the bar code at a certain position on the signature picture, wherein the preferred position is the left side or the right side of the picture. The two-dimensional code is characterized in that the ground color is not original white, but the picture inserted in the step 2 is used as the ground color, so that the two-dimensional code can be prevented from being falsified by artificial picture editing software such as Photoshop and the like in the later period. With the two-dimensional code or the bar code, the signature picture can be called out and compared with the archived picture on the cloud server at any time by scanning the two-dimensional code or the bar code at a later stage, and the authenticity of the signature is further verified.
And after the step 4 or the step 5 is finished, clicking to store the signature, storing the signature locally, or sharing the signature on common communication chatting software, mails and the like. When the signature is clicked and stored, the software system automatically stores the information and the picture of the signature in the software and on the cloud server as a historical file for storage, so that a user can conveniently check the historical signature in the later period to verify the authenticity of a certain signature before. (note: a clickable system setup button is set in the system in advance to decide whether to save the signature information onto the cloud server).
In addition, referring to fig. 1, against the background, fig. 1 shows the signature effect without anti-counterfeit effect in the prior art.
