< method examples >
Fig. 1 is a schematic flow chart of a method for verifying forgery prevention of a printout document according to an embodiment of the present disclosure, which may be implemented by an electronic device.
As shown in fig. 1, the anti-counterfeit verification method for a printout file of this embodiment may include the following steps 1100 to 1500:
and 1100, acquiring raster anti-counterfeiting contents and anti-counterfeiting code position information.
The grating anti-counterfeiting content is used for file anti-counterfeiting, and the grating anti-counterfeiting contents of different files can be the same or different. When the authenticity of the file is verified, the authenticity of the file can be obtained only by acquiring the grating anti-counterfeiting content through the decoding sheet.
Alternatively, the raster security content may be set by the user, and the user may configure the raster security content according to his or her own needs, for example, the user may input the raster security content through an input device of the electronic device. At this time, the electronic device may obtain the grating anti-counterfeiting content configured by the user. Or, the electronic device may also randomly generate the grating anti-counterfeiting content according to the anti-counterfeiting file. This embodiment is not particularly limited thereto.
Similarly, the anti-counterfeiting code position information can also be set by a user, for example, if the user wants to display the anti-counterfeiting code on the upper right corner of the anti-counterfeiting file, the user can input the upper right corner of the page as the anti-counterfeiting code position information through an input device of the electronic equipment, and the anti-counterfeiting code position information is acquired by the electronic equipment. Or, the anti-counterfeiting code position information may also be determined according to a preset position, for example, if the anti-counterfeiting code is preset in the electronic device and displayed in the upper right corner of the anti-counterfeiting file, the obtained anti-counterfeiting code position information is the upper right corner of the page. And is not particularly limited herein.
Specifically, the grating anti-counterfeiting picture can be generated according to the grating anti-counterfeiting content by writing Java codes by using an optical anti-counterfeiting watermarking technology. Therefore, the grating anti-counterfeiting picture has different grating anti-counterfeiting contents seen from different angles, and has better anti-counterfeiting effect.
Illustratively, when the electronic device generates the grating anti-counterfeit picture, a transverse anti-counterfeit picture and a longitudinal anti-counterfeit picture may be generated specifically according to the grating anti-counterfeit content; and then generating the grating anti-counterfeiting picture according to the transverse anti-counterfeiting picture and the longitudinal anti-counterfeiting picture.
In a feasible implementation manner, when the electronic device generates the grating anti-counterfeiting picture according to the transverse anti-counterfeiting picture and the longitudinal anti-counterfeiting picture, the transverse anti-counterfeiting picture and the longitudinal anti-counterfeiting picture can be superimposed to generate an anti-counterfeiting picture to be covered; then generating a mask layer picture in a random direction; and finally, combining the mask layer picture and the anti-counterfeiting picture to be covered to obtain the grating anti-counterfeiting picture.
It can be understood that, in practical application, the transverse anti-counterfeiting picture can be used as a first layer picture, the longitudinal anti-counterfeiting picture can be used as a second layer picture, and then the randomly generated mask layer pictures can be used as a third layer picture to be combined to obtain the grating anti-counterfeiting picture; or the longitudinal anti-counterfeiting picture can be used as a first layer picture, the transverse anti-counterfeiting picture can be used as a second layer picture, and then the randomly generated mask layer pictures can be used as a third layer picture to be combined to obtain the grating anti-counterfeiting picture. In combination with the actual anti-counterfeiting requirement, 2 to 3 layers, or even more layers of mask layer pictures can be randomly generated, which is not specifically limited in this embodiment.
1300, generating an anti-counterfeiting code according to the acquired anti-counterfeiting file access address.
In this step, the anti-counterfeit code is an access address of the anti-counterfeit file, and the electronic device can generate corresponding anti-counterfeit codes according to different access addresses of different anti-counterfeit files. Illustratively, the anti-counterfeiting code can be a two-dimensional code, and the two-dimensional codes generated by different anti-counterfeiting files are different.
And 1400, writing the grating anti-counterfeiting picture and the anti-counterfeiting code into a corresponding position of the anti-counterfeiting code position information in the anti-counterfeiting file text uploaded by a user to obtain the anti-counterfeiting file to be printed.
Specifically, the electronic device may determine a writing position of the grating anti-counterfeit picture in the body text of the anti-counterfeit file; and writing the grating anti-counterfeiting picture into a corresponding position in the anti-counterfeiting file body according to the writing position to obtain the anti-counterfeiting file to be printed.
It should be noted that the grating security image and the security code may be written into each page of the security document, or may be written into any one or more pages of the security document, which is not limited herein.
And 1500, outputting the anti-counterfeiting file to be printed.
In the embodiment, the anti-counterfeiting content and the anti-counterfeiting code position information of the grating are obtained; generating a grating anti-counterfeiting picture according to the grating anti-counterfeiting content; generating an anti-counterfeiting code according to the acquired anti-counterfeiting file access address; writing the grating anti-counterfeiting picture and the anti-counterfeiting code into a corresponding position in an anti-counterfeiting file body uploaded by a user to obtain an anti-counterfeiting file to be printed; and outputting the anti-counterfeiting file to be printed. According to the embodiment of the disclosure, the grating anti-counterfeiting picture and the anti-counterfeiting code can be written in the corresponding position of the anti-counterfeiting file to be printed, and the grating anti-counterfeiting picture is generated according to the grating anti-counterfeiting content input by a user, so that the anti-counterfeiting file which is difficult to copy can be obtained, and a good anti-counterfeiting effect is realized.
Fig. 2 is a process flow schematic of another anti-counterfeit verification method for a printout document according to an embodiment of the disclosure. The present embodiment may specifically be executed by an electronic device.
As shown in fig. 2, the anti-counterfeit verification method for a printout file of this embodiment may specifically include the following steps 2100 to 2300.
The electronic equipment can scan the anti-counterfeiting code on the anti-counterfeiting file to be verified by using the camera device, so that the electronic equipment jumps to the anti-counterfeiting file access address corresponding to the anti-counterfeiting code and opens the corresponding anti-counterfeiting file.
The anti-counterfeiting code and the grating anti-counterfeiting picture are printed at a preset position in the anti-counterfeiting file to be checked; the anti-counterfeiting code is generated according to an anti-counterfeiting file access address, and the grating anti-counterfeiting picture is generated according to grating anti-counterfeiting content.
In this step, when determining whether the anti-counterfeit file to be verified is a counterfeit file according to the acquired grating anti-counterfeit picture, the electronic device may acquire the grating anti-counterfeit picture from a first angle, as shown in fig. 3, the grating anti-counterfeit content on the grating anti-counterfeit picture is 4531, and compare the grating anti-counterfeit picture from the first angle with a first preset picture to obtain a first comparison result; acquiring the grating anti-counterfeiting picture from a second angle, wherein grating anti-counterfeiting content on the grating anti-counterfeiting picture is 3TBF (temporary flow Block) as shown in figure 4, and comparing the grating anti-counterfeiting picture at the second angle with a second preset picture to obtain a second comparison result; when the first comparison result and the second comparison result are consistent, determining that the anti-counterfeiting file to be verified is not the counterfeit file; and when the first comparison result or the second comparison result is inconsistent, determining that the anti-counterfeiting file to be verified is the counterfeit file.
In the embodiment, the anti-counterfeiting code on the anti-counterfeiting file to be verified is scanned to obtain the anti-counterfeiting file to be verified; acquiring a grating anti-counterfeiting picture on the anti-counterfeiting file to be verified by using a decoding sheet; and determining whether the anti-counterfeiting file to be verified is a forged file or not according to the acquired grating anti-counterfeiting picture. According to the embodiment, the grating anti-counterfeiting picture and the anti-counterfeiting code of the anti-counterfeiting file to be printed can be used, and the grating anti-counterfeiting picture is generated according to the grating anti-counterfeiting content input by a user, so that the anti-counterfeiting file which is difficult to copy can be obtained, and a good anti-counterfeiting effect is realized.
