The present invention relates to a vector image implementation method for outputting a high-resolution two-dimensional barcode, and the present invention provides a high-resolution print quality by generating a vector image of a two-dimensional barcode that has been generated based on a conventional bitmap image. The first object is to provide an output technology, and the second object is to solve the problem that a conventional two-dimensional barcode is generated as a bitmap image having a large capacity and causes overload of a server.

Hereinafter, a detailed description of the present invention for achieving the above object will be described with reference to the accompanying drawings, and a plurality of drawings may be simultaneously referenced to describe one or more technical features or components constituting the invention. will be.

Referring first to FIG. 1, FIG. 1 is a flowchart of a vector image implementation method for outputting a high-resolution two-dimensional barcode according to an embodiment of the present invention.

Specifically, in the present invention, a certificate issuance request step (S10) is performed in which a user terminal accesses a web server providing a certificate issuance service and requests issuance of a certificate to be issued.

At this time, the above-described web server is a server built by an issuing authority to issue a certificate, and can be understood as a concept of a server that provides a service for issuing a certificate online. The aforementioned issuing authority is, for example, a government office, It can be understood as a concept of institutions that issue certificates, such as schools and companies.

As a more detailed example, if the issuing authority is a government office, the certificate is various copies. It can be an abstract, family relation certificate, national pension subscription certificate, etc. If the issuing institution is a school, the certificate can be a certificate of enrollment, graduation certificate, degree certificate, etc. If the issuing institution is a company, the certificate can be a certificate of employment , contract confirmation, various official documents and certificates.

When the issuance of the certificate is requested from the user terminal by performing the above step S10, the above-described web server communicates with the WAS server on a network basis, generates the certificate requested by the user terminal as an electronic certificate in the WAS server, and generates the electronic certificate. A certification file providing step (S20) of inserting a barcode image for preventing forgery/falsification into the certificate and providing the certificate file with the barcode image inserted thereto to the user terminal is performed.

At this time, when the above-described step S20 is performed, the above-described WAS server has a form required for the electronic certificate to be issued, so that an electronic certificate based on the held form can be generated, and the above-described WAS server Data communication may be performed with the terminal through a web communication protocol including at least one of http and https.

In addition, in step S20 described above, a barcode image for preventing forgery/falsification is inserted into the generated electronic certificate as described above.

As an embodiment, in step S20, an electronic signature including a hash value for the original certificate (original certificate) and an authentication value in the WAS server can be performed on the certificate, and this electronic signature can be performed through the developed API. It is converted into a barcode image, inserted into the certificate as invisible data, processed into a certificate that is prevented from forgery/falsification, and then provided to the user terminal.

In addition, in step S20 described above, as a result of determining whether an application program for reading a barcode image is installed in the user terminal, when it is confirmed that the application program is installed in the user terminal, the certificate file is provided in the form of a PDF file to provide the user The terminal may be able to view the certificate file through an application program, and the present invention is not limited thereto.

Subsequently, after performing the above-described step S20, in order to read the barcode image present in the certificate file, a barcode for extracting barcode identification information inserted into the certificate file using a means including at least one of a web browser and an application program. An identification information extraction step (S30) is performed.

Preferably, in step S30 described above, the barcode image is read and output by dividing it into a barcode data area and a pattern mark area. (Binary digit) value, and the above-described pattern mark area is information (fixed value) for recognizing that it is a two-dimensional barcode, and the mark for calculating the position correction and rotation angle of the two-dimensional barcode It is desirable to be understood as a concept.

In detail, referring to FIG. 5, an example of a two-dimensional barcode is shown. In FIG. 5, 2000 is a pattern mark area, 2100 in FIG. 5 is a barcode data area, and 2200 in FIG. 5 is a pattern mark area and a barcode data area. A combined example will be appreciated.

Returning to FIG. 1, in step S30 of FIG. 1, the barcode data area is converted into a bit (binary digit) value and stored, which stores the barcode image as text, and the capacity of the 2D barcode that was stored based on the existing bitmap image By functioning to significantly reduce the load generated on the server, it can exert an effect of reducing the load.

Meanwhile, after the step S30 is performed, the output data processing step (S40) of generating a vector image based on the extracted barcode identification information and processing it into data for printer output is performed.

At this time, in step S40 described above, data for printer output is processed in different ways according to the type of means for extracting barcode identification information in step S30 described above.

Specifically, in step S40, when a web browser is used as a means of extracting barcode identification information, the barcode image is converted into graphic data using the canvas function of the HTML5 standard, and then the output of the physical certificate is requested from the user terminal When it is done, the converted graphic data can be rendered on the certificate so that the data for printer output can be processed, and in detail, as the data for printer output, it is defined as an xml file so that a script can be created or compressed, and a vector image can be implemented only with HTML. It can be processed in the form of an SVG file that creates an environment.

In addition, as another embodiment of the above-described step S40, in the present invention, when an application program is used as a means of extracting barcode identification information, in the present invention, the GDI function is applied to the printer device context and bit values stored in the database are used to obtain the certificate. A two-dimensional barcode that is output together can be drawn as a vector image.

At this time, the implementation of the vector image by the above-described drawing method does not recognize the 2D barcode as an image, but rather recognizes it as a figure and precisely expresses the objects constituting the 2D barcode one by one through the graphics device interface, which is an application program interface ( GDI (Graphics Device Interface) can be used, and this method of generating a two-dimensional barcode can generate a high-resolution two-dimensional barcode even at a rather slow printing speed, greatly improving the barcode recognition rate.

Meanwhile, after performing the above-described step S40, a preview interface window for the actual certificate to be output may be provided to the user terminal, which includes a two-dimensional barcode to be output on the display provided in the user terminal before output of the actual certificate. It may be to perform a process of receiving confirmation from the user by allowing the verified certificate to be viewed.

At this time, it is preferable to output a certificate including a two-dimensional barcode corresponding to the screen size of the display of the user terminal at a 1:1 magnification in the preview interface window, so that substantial browsing can be performed. Control of the output magnification of the certificate including the 2D barcode may be performed to correspond to the screen size of the terminal, but the present invention is not limited thereto.

Next, after the above-described step S40 is performed, a real certificate output step (S50) is performed to output the processed printer output data as a real certificate through a printer connected to the user terminal.

At this time, it can be understood that the certificate including the 2D barcode is output on paper or the like by dynamically processing the 2D barcode and generating a vector image for the physical certificate output in step S50 described above.

In particular, in the present invention, the 2D barcode included in the certificate is converted into a vector image and implemented in high resolution, thereby significantly increasing the print quality of the 2D barcode and solving the low recognition rate problem of the bitmap image-based 2D barcode. .

Meanwhile, referring to FIG. 2 next, it can be seen that FIG. 2 is a conceptual diagram of a vector image implementation method for outputting a high-resolution two-dimensional barcode according to an embodiment of the present invention.

The present invention largely includes a web server 100 that manages certificate issuance. At this time, the web server 100 includes a WAS server 102 that supports a web service for certificate issuance, and a forgery/falsification prevention system 101 that prevents forgery/falsification by giving hash values and authentication values to certificates to be issued. This web server 100 can communicate with the user terminal 200 based on the above-described communication protocol, and transmit/receive data for certificate issuance in both directions.

Meanwhile, the user terminal 200 has

web browsers

201 and 202 and an application program 203 installed so that it can access the issuing server or the WAS server 102 built in the issuing server, and the

web browsers

201 and 202 Services such as web pages or web applications of the web server 100 or the WAS server 102 may be supported.

In addition, the

web browsers

201 and 202 may request the issuance of a certificate to the web server 100 at the request of the user terminal 200, and the forgery/falsification prevention system 101 performs the function of preventing forgery/falsification. For the electronic certificate, a two-dimensional barcode image converted into a vector image is generated in the output module 300 and output as a physical certificate through the printer 30 interlocked with the user terminal 200 .

Meanwhile, the output module 300 may include a module installed in the user terminal 200 and a module not installed, and the present invention is not limited thereto.

Referring next to FIG. 3, it can be seen that FIG. 3 illustrates an embodiment for explaining that the capacity of a barcode image is reduced according to an embodiment of the present invention.

In general, the barcode image 1100 is a high-resolution image, and since lossy compression cannot be performed, the capacity is inevitably large. Accordingly, in the present invention, the barcode image 1100 is expressed by dividing it into a barcode data area and a pattern mark area.

In the embodiment of FIG. 3 , an embodiment in which 9

pixels

1110 and 1111 are converted into 1 bit value 1200 as identification information for the barcode data area and extracted, thereby exhibiting a compression effect of 1/9, will be looked at. can

That is, in the present invention, the barcode data area is stored as a bit value representing dynamic data rather than an image, and when output of a 2D barcode is requested, the stored bit value is read and a 2D barcode is generated in real time, thereby converting vector imaging. 2D barcode output can be obtained.

On the other hand, in A and B of FIG. 4, after printing a 600dip bitmap image-based 2D barcode and a vector image-based 2D barcode according to the embodiment of the present invention, they were photographed with a magnifying glass so that the print quality could be compared, As clearly shown in FIG. 4 , it can be confirmed that the 2D barcode according to the embodiment of the present invention has a higher resolution than the 2D barcode based on a bitmap image.

That is, overall, according to an embodiment of the present invention, a 2D barcode image generated as a conventional bitmap image can be processed into binary data to reduce capacity by 90% or more, thereby greatly reducing server load. At the same time, there is an effect of greatly increasing the barcode recognition rate by printing a high-resolution barcode by printing a vector image.
