Detailed Description
The technical solutions in the embodiments of the present invention are clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the scope of the present invention.
In view of the fact that the existing method cannot realize a rapid and convenient data carrier acquisition method meeting the requirements of different application scenes, the embodiment of the invention provides a method for acquiring a two-dimensional code data carrier.
Example one
The embodiment provides a method and a device for identifying a two-dimensional code data carrier, as shown in fig. 1, the design flow of the invention is as follows:
1. bill information input
The entry of the bill information can be the information collection which is charged by an authority unit. Of course, this method is mainly used for special bills issued by special units, such as invoices. Common bills such as other vouchers can be filled in through self-service information to complete the entry.
The ticket information here is generally, but not limited to: the company name number contacts the telephone address product name amount and the like;
2. generating two-dimensional code
The two-dimensional code is a high-capacity two-dimensional code. The two-dimensional code can support the total amount of bill information, namely, the bill information can be encoded into binary data and stored in the two-dimensional code. The two-dimensional code can also store related information on the bill, such as only the name of a company on the bill, but can store other sensitive and critical information such as a contact telephone of the company and the like in the two-dimensional code. The generation process of the two-dimensional code is an independently developed generation program and is a non-public generation method. The generation process combines various encryption and compression technologies, and the structure rule is complex and difficult to crack. The various encryption techniques described above may be asymmetric encryption, symmetric encryption, and the like. The compression techniques described above are primarily binary compression algorithms. Therefore, the two-dimensional code is not counterfeitable and is not falsifiable, and the safety of data can be ensured. All data are stored in the two-dimensional code, so that a server is not needed to support data storage, and the cost is greatly saved. The information of the original database is born by one two-dimensional code, and the decentralization of the data is realized.
Presenting two-dimensional code and bill in combination
The two-dimensional code can be directly combined with the electronic bill, and the two-dimensional code is directly coded on the electronic bill. Or another pdf page can be used for storing two-dimensional codes, and a new pdf document can be generated together with the electronic bill.
The two-dimensional code can be displayed together with the bill, and the two-dimensional code is generally displayed below the bill. When printing the bill, directly print the two-dimensional code together. Of course, the two-dimensional code can also be attached to the bill in a label pasting mode.
4. Validating tickets using custom devices or apps
The customization equipment is equipment containing a two-dimensional code analysis program. The customization device can be divided into the following 5 parts;
the input part is used for receiving the two-dimensional code;
and (3) an analysis part: the two-dimension code analysis program is used for analyzing the two-dimension code to obtain encrypted data;
and a decryption part: decrypting the data by using the asymmetric secret key in the equipment, and acquiring signature part information according to an integration rule;
and a comparison part: for comparison of signatures, and other biometric comparisons;
the presentation part: the method is used for presenting results, and the presenting mode can be diversified and different between two parties or between three parties;
the device type may be: pad, mobile phone, custom android device, etc. The mobile phone may use an app on the mobile phone, or may be an applet or the like. If the program is a small program, the bill verification can be realized under the condition of a network.
The two-dimensional code can be analyzed only by the customized equipment, so that the privacy and authority of the information are guaranteed.
The customized device contains the encrypted signature of the subject company, and the two-dimensional code also contains the encrypted signature of the company. The setting can guarantee the safety of the customization equipment, and meanwhile, the equipment and the two-dimensional code are bound, so that double-layer guarantee is achieved. If a lawbreaker wants to steal information or forge information, he must steal the generated code and modify the device by himself, which is a great difficulty and cost.
And the verification process after the decryption is finished can be naked eye data comparison or OCR comparison can be directly realized. Firstly, the authority of the data is realized if the decryption is successful, and then the data is compared, so that the authenticity and the effectiveness of the data can be proved. Therefore, the method can realize the anti-counterfeiting of the bill and protect the safety of the information and the main body.
And after the decryption is completed, the two-dimensional code can also contain other related information, such as a business contact telephone, besides the information of the bill. The method and the device can protect sensitive information and provide convenient information acquisition for related personnel.
According to the invention, all data are stored in the two-dimensional code, and the analysis program is also arranged on the equipment. Therefore, the invention can complete the verification process in an off-line state.
In summary, the method for acquiring the data carrier of the two-dimensional code provided by the embodiment of the invention has the following beneficial effects:
(1) the bill based on the two-dimensional code can verify the authenticity of the bill under an off-line condition, thereby enhancing the adaptability of the bill to the environment and expanding the application range;
(2) the two-dimensional code bill can store other information except the bill, protect private information and meanwhile enhance targeted transmission of the information;
(3) the two-dimensional code in the bill is an information carrier, the support of a huge database is not needed, the data cost is saved, the decentralization is realized, the risk of database leakage is avoided, and the safety is improved.
The above-mentioned embodiments, objects, technical solutions and advantages of the present invention are further described in detail, it should be understood that the above-mentioned embodiments are only examples of the present invention, and are not intended to limit the scope of the present invention, and any modifications, equivalent substitutions, improvements and the like made within the spirit and principle of the present invention should be included in the scope of the present invention.
