Detailed Description
To further explain the technical means and effects of the present invention adopted to achieve the predetermined objects, the following detailed description will be provided with reference to the accompanying drawings and preferred embodiments for describing specific embodiments, structures, features and effects thereof.
Please refer to fig. 1, which is a flowchart illustrating a method for generating a two-dimensional electronic ticket according to an embodiment of the present invention. As shown in fig. 1, in the two-dimensional code electronic ticket generating method of this embodiment, first, the two-dimensional code electronic ticket generating system generates a set of public key and private key for the ticket event, where the private key is used to encrypt selected attribute information in the basic attribute information of the ticket. In this embodiment, the basic attribute information includes, for example and without limitation, information such as a subsequently assigned unique number, authentication entry information, a name of an electronic ticket purchaser, a mobile phone number, an event name, an event location, an event date, an event time, a seat number, and the like, so as to ensure authenticity of the generated two-dimensional code electronic ticket; the public key is used for subsequent provision to the verification terminal for decrypting the ciphertext of the selected attribute information encrypted by the private key.
After necessary information of the entrance ticket is obtained, the two-dimensional code electronic ticket generating system distributes a unique number and verification entrance information to the entrance ticket, calculates a hash value of selected attribute information of the entrance ticket, including the unique number, the verification entrance information and other attribute information, and the like, carries out encryption operation on the calculated hash value by using a private key of the ticket event to obtain a hash value ciphertext, carries out base64 encoding on the hash value ciphertext, and then generates a two-dimensional code electronic ticket corresponding to the entrance ticket by using basic attribute information of the entrance ticket, including the unique number, the verification entrance information and other necessary attribute information, and base64 encoding data of the hash value ciphertext.
In this embodiment, the hash value is calculated for the selected attribute information of the ticket, and the base64 encoding is performed on the hash value ciphertext, so that the information capacity of the two-dimensional code electronic ticket can be reduced, and the identification rate can be improved. Thus, it is to be understood that in other embodiments, it is also contemplated that the selected attribute information may be directly encrypted and used using the private key of the ticketing campaign without performing hash value calculation and/or base64 encoding operations; alternatively, other algorithms may be used to pre-process the selected attribute information of the ticket before the private key is used for encryption and/or other algorithms may be used for encoding after the private key is used for encryption, and the algorithm is not limited to the hash algorithm and the base64 encoding algorithm of the present embodiment.
Please refer to fig. 3, which is a functional module diagram of a two-dimensional code electronic ticket generating system according to an embodiment of the present invention. As shown in fig. 3, the two-dimensional code electronic ticket generating system 30 of the present embodiment is responsible for generating a two-dimensional code electronic ticket according to an order form of a user, and includes: the system comprises a key generation module 31, an information distribution module 33, a private key encryption module 35, a base64 encoding module 37 and a two-dimensional code electronic ticket generation module 39.

Wherein, the key generating module 31 is used for generating a set of public key and private key for a specific ticket activity, for example; the information distribution module 33 is used for distributing a unique number and verification entrance information for a ticket in the ticket event; the private key encryption module 35 is, for example, configured to encrypt a hash value (i.e., an expression of the selected attribute information) of the selected attribute information of the ticket using a private key of the ticketing event to obtain a hash value ciphertext; the base64 encoding module 37 is, for example, configured to base64 encode the hash value ciphertext of the selected attribute information to obtain base64 encoded data of the hash value ciphertext; the two-dimensional code electronic ticket generating module 39 is, for example, configured to generate a two-dimensional code electronic ticket corresponding to the ticket by using base64 encoded data of the ticket, which includes basic attribute information including a unique number and verification entry information, and a hash value ciphertext. It should be understood that the two-dimensional code electronic ticket generating system 30 of the present embodiment may also omit the base64 encoding module, or replace the base64 encoding module with another encoding module; in addition, the private key encryption module 35 may also directly perform an encryption operation on the selected attribute information using the private key of the ticketing campaign, instead of performing an encryption operation on the hash value thereof.
Please refer to fig. 2, which is a flowchart illustrating a two-dimensional electronic ticket verification method according to an embodiment of the present invention. As shown in fig. 2, in the two-dimensional code electronic ticket verification method of this embodiment, first, a verification terminal needs to obtain a public key of the ticketing event, a unique number assigned to the verification terminal, and verification entry information binding the verification terminal (i.e., binding the unique number of the verification terminal) from a service system of the two-dimensional code electronic ticket (e.g., the two-dimensional code electronic ticket generation system 30 in fig. 3), so that the verification terminal is subsequently responsible for verifying only the two-dimensional code electronic ticket with the binding verification entry information.
And then, during ticket checking and verification, the verification terminal scans the two-dimensional electronic ticket to obtain two-dimensional code data contained in the two-dimensional electronic ticket, and analyzes the obtained two-dimensional code data to obtain base64 coded data of a ticket corresponding to the two-dimensional electronic ticket, wherein the base attribute information comprises a unique number, verification entrance information and other necessary information, and a hash value ciphertext of the selected attribute information.
After the two-dimensional code data are analyzed, firstly, the authenticity of the current two-dimensional code electronic ticket is judged, which specifically comprises the following steps: base64 decoding is carried out on the base64 coded data of the hash value ciphertext obtained through analysis to obtain the hash value ciphertext, and the decoded hash value ciphertext is decrypted by using the public key of the ticket activity to obtain hash value plaintext hash 2; next, performing hash operation on selected attribute information including the unique number and the verification entry information in the analyzed basic attribute information to obtain a hash value hash 1; and then, comparing whether the hash value hash1 is consistent with the hash value plaintext hash2, if the hash value hash1 is inconsistent with the hash value plaintext hash2, indicating that the current two-dimensional code electronic ticket is a false ticket, otherwise, if the hash value hash1 is consistent with the hash value plaintext hash2, indicating that the current two-dimensional code electronic ticket is a true ticket.
And then, judging whether the current two-dimensional code electronic ticket is verified at the verification terminal by using the verification entrance information obtained by analysis. If the analyzed verification entrance information is not matched with the verification entrance information of the binding verification terminal acquired from the service system previously, the verification terminal indicates that the current two-dimensional code electronic ticket is not verified at the verification terminal, and a ticket holder is prompted to go to a specified verification entrance for ticket checking verification; and if the two are matched, judging whether the current two-dimensional code electronic ticket is used or not by using the unique number of the ticket obtained by analysis. If the unique number of the ticket obtained by analysis is inquired in the local storage of the verification terminal to find that the unique number exists, the fact that the current two-dimensional code electronic ticket is used is prompted, if the unique number cannot be inquired, the fact that the current two-dimensional code electronic ticket is not used is indicated, a ticket holder is allowed to pass, and the unique number of the current two-dimensional code electronic ticket is recorded to the verification terminal to be stored locally; the unique serial number of the electronic ticket does not need to be downloaded to the verification terminal in the verification mode, leakage of the unique serial number of the electronic ticket is prevented, and safety of the electronic ticket scheme is improved.
In addition, after the ticket checking of the ticketing event is finished, the verification record information of the two-dimensional code electronic ticket in the verification terminal needs to be uploaded to a service system of the two-dimensional code electronic ticket, so that the service system of the two-dimensional code electronic ticket can obtain the use condition of the two-dimensional code electronic ticket. In addition, it can be understood that the two-dimensional code electronic ticket verification process is a reverse process of the two-dimensional code electronic ticket generation process to some extent, and therefore whether base64 decoding is required in the two-dimensional code electronic ticket verification process depends on the generation process.
Please refer to fig. 4, which is a schematic diagram of a functional module of a two-dimensional electronic ticket verifying terminal according to an embodiment of the present invention. As shown in fig. 4, the two-dimensional code electronic ticket verifying terminal 40 of the present embodiment implements authenticity judgment and verification of the two-dimensional code electronic ticket and stores a unique number of the two-dimensional code electronic ticket to implement reuse judgment of the two-dimensional code electronic ticket, and includes: a scanning module 41, an analysis module 43, an authenticity judgment module 45, a verification entry judgment module 47 and a use state judgment module 49.
Specifically, the two-dimensional code electronic ticket verification terminal 40 of the present embodiment may be used to execute the two-dimensional code electronic ticket verification method of the foregoing embodiment of the present invention. The scanning module 41 is, for example, configured to acquire two-dimensional code data in a current two-dimensional code electronic ticket; the parsing module 43 is used for parsing out base64 encoded data of a hash value ciphertext of the ticket including the unique number, the verification entry information and other necessary information and the selected attribute information (including the unique number and the verification entry information) from the current two-dimensional code data, for example; the authenticity judgment module 45 is configured to, for example, decrypt the hash value ciphertext by using the public key of the ticketing event, and compare the hash value plaintext obtained after decryption with a hash value obtained by performing hash operation on selected attribute information including a unique number and verification entry information in the basic attribute information analyzed from the two-dimensional code data of the current two-dimensional code electronic ticket to judge authenticity of the current two-dimensional code electronic ticket; the verification entrance judging module 47 is, for example, configured to judge whether the current two-dimensional code electronic ticket is verified at the verification terminal by using the verification entrance information; the use state judgment module 49 is used for judging whether the two-dimensional code electronic ticket is used currently by using the unique number.
