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.
Example one
The embodiment provides a two-dimensional code-based method and device for offline identification of a pass, as shown in fig. 1, the process includes:
1. entering pass information
Firstly, a signing and issuing unit is required to acquire information required by a pass, and the information can be as follows: name, certificate number, expiration date, vehicle information, etc. In addition, in addition to information on the pass, some personal information of relative privacy of the relevant person may be collected. The part of the information will not be displayed on the pass, but when decoding software is used, an authentication flow is set, if the authentication flow is passed, the privacy-related personal information is displayed, and if the authentication flow is not passed, the display of the information is suspended. Such as an organization contacting a telephone. The method and the device can protect sensitive information and provide convenient information acquisition for related personnel. The authentication process may be an authentication process of identifying the level of the device itself, inputting a verification code, a signature, and the like.
When the biological information is collected, the method comprises the step of collecting a picture of the corresponding person, or a fingerprint characteristic value and/or an iris characteristic value.
2. Collecting information, combining signing and issuing unit signature, and generating two-dimensional code
The signature of the issuing unit may be: the signature information may be in the form of a name of a company, a unit, or an individual.
Other characteristic symbols such as company Logo may also be used.
The two-dimensional code is a high-capacity two-dimensional code, at least comprises 320 bits, and can support the total amount of information, namely the pass information can be encoded into binary data and stored in the two-dimensional code. The generation process of the two-dimensional code is an independently developed generation program, various encryption and compression technologies are combined, 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. The two-dimensional code is not counterfeitable and is not falsified, and the safety of data can be guaranteed. All data are stored in the two-dimensional code, so that a server is not needed for supporting 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 pass in combination
The two-dimensional code can directly combine the pass, directly with the two-dimensional code to on the pass. Of course, the two-dimensional code can also be attached to the pass by means of label adhesion.
The two-dimensional code can also be directly used as a carrier for information transmission. That is, a two-dimensional code is a pass. Therefore, you can directly store the two-dimensional code as a picture in own mobile equipment for use. When you need to show for others or others want to acquire your pass, the other party directly scans and analyzes your two-dimensional code to acquire the information in the code, and the passing authority of your person is proved. The mode has safe assurance promptly, can prevent losing of paper pass again, has also solved the inconvenient problem of pass carrying in the usual life.
Decrypting to obtain biological characteristics, and performing biological verification
And the biological characteristics of the participants are recorded in the two-dimensional code, and the participants are checked again by using a biological characteristic interface carried in the decoding software.
And if the face is checked, calling a face checking interface in the decoding software. The face of the conference participants is compared with the face characteristic value in the two-dimensional code.
If the fingerprint is verified, a fingerprint verification interface in the decoding software is called. The fingerprints of the participants are collected on site and compared with the fingerprint characteristic values in the two-dimensional code.
If the iris verification is performed, an iris verification interface in the decoding software is called. The irises of the participants are acquired on site and compared with the iris characteristic value in the two-dimensional code.
This operation is relatively time consuming, but may further prove the passage rights of the conference participants. Of course, if the information of the previous two steps can be confirmed to be correct, the right of the person can be confirmed in principle. To speed up the mobility of the persons or vehicles at the gate, biometrics may be used as a back-up authentication scheme for the last step.
After the biological verification passes, obtaining the pass information in the two-dimensional code through decoding software
When a participant or a vehicle passes through a gate, a signing and issuing unit or a related person in charge needs to use decoding software to analyze a pass carrying a two-dimensional code or a single two-dimensional code which can prove authority and is held by the participant, and obtain all information in the code.
The presentation mode is an electronic pass original A and other data B of the conference participants. The responsible person can compare the authenticity of his pass by the human eye. If there is a question, the person in charge can ask the meeting participants to present other certificates to prove the material B in the electronic material. The pass can be considered to be true and effective if the data is compared without errors.
The presentation process further includes a step of presentation after authentication, and if the authentication flow is passed, information such as the personal information related to privacy is displayed, and if the authentication flow is not passed, the display of the information is suspended. The authentication process may be an authentication process of identifying the level of the device itself, inputting a verification code, a signature, and the like.
Comparing the signature in the software with the signature information in the two-dimensional code
The decoding software contains the same information as the two-dimensional code or the information in the correlation relationship. The correlation is that signature information of one party can be converted or calculated by a certain rule to obtain signature information of the other party.
The operation of signature comparison can ensure the safety of decoding software, and simultaneously, the binding of the software and the two-dimensional code is realized, thereby realizing double-layer guarantee. If a lawbreaker wants to steal information or forge information, he must steal the generated code and crack the decoding software by himself. This is almost impossible at the technical level and also enormous in cost, avoiding illegal actions by lawbreakers.

The carrier of the decryption program may be a device or may be a software app. The decoding program can decrypt and obtain the data in the two-dimensional code. Data acquisition will no longer require network and database support. This arrangement enables information to be acquired in an offline state. The scheme does not depend on a regional network any more, reduces the requirement of the use environment and saves the network cost in use. Meanwhile, the problem of common faults and high concurrency of the network server is solved in an off-line mode.
In the process of verification, the invention sets a three-layer verification mode,
