Description
Technical Field
The invention relates to the technical field of rail transit, in particular to a ticket checking method, a gate, a server, a mobile terminal and a storage medium.
Background
At present, in an urban rail transit system, based on communication between a smart phone, a gate and a ticketing center server, a passenger can use the smart phone to verify on the gate at an entrance and exit to open a gate, for example, the passenger can present a two-dimensional code to a code scanning area of the gate at an exit point through the smart phone to open the gate, the gate at the exit point can send an exit point of the user to the ticketing center server, and the ticketing center server sends an opening command to the gate at the exit point after the completion of toll settlement and deduction of the toll of the passenger. Because the gate machine of the ticket center needs to communicate with the ticket center server during the passenger outbound period, and the calculation burden of the ticket center server is large during the passenger outbound period, the ticket center server often needs to meet the requirement of the passenger for rapid outbound by strong computing capability and dependence on rapid network speed.
Disclosure of Invention
In view of the above, the present invention provides a ticket checking method, a gate, a server, a mobile terminal and a storage medium, so as to meet the requirement of a passenger on rapid departure. Specifically, the present invention can achieve the following objects: firstly, when a passenger leaves the station, the gate machine for leaving the station does not need to communicate with the ticket center server, and the ticket center server does not need to settle the bus fee when the passenger leaves the station, so that the time for the passenger to leave the station is reduced; and secondly, the passengers can be ensured to normally exit in an off-line state of the gate at the exit point.
In a first aspect, in an embodiment of a method for checking tickets, the method for checking tickets is applied to an exit gate of a rail transit system, and the method comprises: receiving ticket buying voucher information from a mobile terminal of a passenger when the passenger leaves the station; the ticket buying voucher information of the mobile terminal is encrypted and issued by the ticket center server by using a public key corresponding to a selected out-stop when a passenger pays the bus fee; attempting to decrypt the ticket purchase credential information through its saved private key; the private key stored by the outbound gate and the public key corresponding to the same outbound point are a key pair; and controlling the gate of the gate machine of the website to open when the ticket purchasing voucher information is decrypted successfully.
Illustratively, the public key and the private key are a key pair obtained by an encryption algorithm, and the ticket purchase credential information encrypted by the public key can be decrypted only by the private key stored by the corresponding outbound gate machine. For example, the outbound point gate may send its generated public key to the ticketing center server at idle time, or the outbound point gate may send its generated public key to the ticketing center server and stored by the ticketing center server at an early stage of establishing a communication connection with the ticketing center server. The outbound gate machine can update the public key and the private key according to a set update cycle, and the safety of data transmission is further improved under the condition that passengers can normally exit. In urban rail transit, a plurality of gate machines at the same exit station store the same private key, and the private keys in different exit station gate machines are different. The passenger can communicate with the ticket center server through the mobile terminal to obtain the ticket buying voucher information in advance before the passenger leaves the station.
For example, the passenger may use his mobile terminal to send his stored ticket voucher information to the gate of the website via two-dimensional code, bluetooth or NFC. When the ticket buying voucher information is decrypted successfully, the outbound point selected by the passenger when the passenger pays the bus fee is corresponding to the outbound gate.
According to the scheme, the private key is stored through the exit gate, the private key is stored by the ticketing center server, the public key and the private key corresponding to the same exit are a key pair, and the ticket buying voucher information is encrypted by the ticketing center server by using the public key corresponding to the exit selected when a passenger pays a bus fee and is issued to the mobile terminal of the passenger. When the passenger sends the ticket-buying voucher information to the exit point gate machine through the mobile terminal of the passenger when the passenger leaves the station, the gate of the passenger can be opened as long as the exit point gate machine can decrypt the ticket-buying voucher information, so that the passenger is allowed to pass through the gate. Therefore, when the passenger leaves the station, the gate machine of the leaving station only needs to verify the ticket buying voucher information sent by the mobile terminal, and does not need to communicate with the ticket business center server, so that the burden of the ticket business center server is greatly reduced, and the requirement of the passenger for fast leaving the station can be met.
In a preferred implementation manner of the method provided in the foregoing embodiment, when the ticket-buying credential information is decrypted successfully, a task of deleting or marking the ticket-buying credential information stored by the mobile terminal as a disabled state is further sent to the mobile terminal. For example, if the ticket-buying voucher information sent by the mobile terminal of the passenger to the gate of the given station is inconsistent with the corresponding exit point of the gate of the exit point, decryption of the ticket-buying voucher information fails, and at this time, the ticket-buying voucher information stored in the mobile terminal is not deleted or invalidated, and the passenger can continue to use the ticket-buying voucher information. The ticket buying voucher information is deleted or invalidated when the decryption is successful, so that the ticket buying voucher information can only be used successfully once.
In a preferred implementation manner of the method provided in the foregoing embodiment, the ticket-buying credential information may include fixed information agreed between the outbound gate machine and the ticket center server; and in the process of attempting to decrypt the ticket purchasing voucher information through the private key, if the fact that the fixed information in the ticket purchasing voucher information is the same as the fixed information agreed between the ticket business center servers is identified, the decryption is successful. For example, the fixed information may be an outbound ID or an outbound name, etc. Under the situation, the gate machine at the out-station does not need to communicate with the ticket service center server when the passenger gets in the station and gets out of the station, so that the gate machine at the out-station can ensure the passenger to normally get out of the station even in an off-line state, and the problem that the passenger cannot normally get out of the station in the off-line state is solved.
In a preferred implementation manner of the method provided in the foregoing embodiment, the ticket-buying credential information includes fixed information agreed between the outbound gateway and the ticketing center server and random information generated by the ticketing center server; before receiving ticket buying voucher information from a mobile terminal of a passenger when the passenger leaves the station, the exit point gate machine also receives the random information from the ticketing center server and stores the random information in a database of the ticketing center server; in the process of trying to decrypt the ticket buying voucher information through the private key stored in the ticket buying voucher information, when the fact that the fixed information in the ticket buying voucher information is identical to the appointed fixed information between the ticket business center server and the random information is inquired in the database of the ticket buying voucher information is identified, the decryption is successful.
For example, the ticket center server may directly send the ticket purchasing voucher information with the fixed information and the random information to the station gate, or send only the random information in the ticket purchasing voucher information to the station gate. The random information may be a random code or random information generated in conjunction with the account information and the time stamp of the passenger. Thus, the security of the ticket purchasing voucher information can be improved.
In a preferred implementation manner of the method provided in the foregoing embodiment, the ticket-buying credential information includes fixed information agreed between the outbound gateway and the ticketing center server and random information generated by the ticketing center server; when the outbound point gate machine successfully decrypts the ticket purchasing voucher information, the outbound point gate machine also sends a task of deleting or marking the ticket purchasing voucher information stored by the mobile terminal as a failure state to the mobile terminal, and deletes corresponding random information stored by the outbound point gate machine from a database of the outbound point gate machine; or after the passenger refunds the ticket, the exit point gate receives a task of deleting the corresponding random information stored in the ticket center server from the ticket center server, and automatically deletes the random information according to the task.
Illustratively, when the passenger leaves the station or in the scene of passenger's ticket refunding after the ticket-buying voucher information is successfully decrypted, the random information stored in the gate of the leaving station is useless, the random information is deleted, the data storage burden of the gate of the leaving station can be reduced, the query amount of the random information in the process of decrypting the ticket-buying voucher information can be reduced by deleting the random information, the ticket-buying voucher information can be rapidly decrypted, and the passenger's leaving station speed is ensured.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail by referring to the following examples.
The ticket checking method provided by the invention can realize the following purposes: firstly, the gate machine 1 of the departure point is not required to be communicated with the ticket center server 2 when the passenger leaves the station, and the ticket center server 2 is not required to settle the riding cost when the passenger leaves the station, so as to save the time required by the passenger leaving the station; and secondly, the passengers can be ensured to normally exit in an off-line state of the gate 1 at the exit point.
In one embodiment of the method for checking tickets provided by the invention, fig. 1 shows a schematic diagram of an information interaction process among an outbound gate 1, a server and a passenger's mobile terminal 3. The process comprises the following steps:
s31, when the passenger buys the ticket, the passenger' S mobile terminal 3 transmits the payment information of the fare and the selected outbound point to the ticketing center server 2.
S21, the ticket center server 2 receives the payment information of the riding fee from the passenger' S mobile terminal 3 and the selected out-stop.
S22, the ticket center server 2 encrypts the ticket-buying credential information by the public key corresponding to the outbound site.
S23, the ticket center server 2 sends the encrypted ticket-buying voucher information to the passenger' S mobile terminal 3.
S32, the passenger' S mobile terminal 3 receives and stores the ticket voucher information from the ticket center server 2.
S33, when the passenger leaves the station, the passenger' S mobile terminal 3 transmits the ticket voucher information to the gate 1 of leaving the station.
S11, the exit gate 1 receives the ticket voucher information from the passenger' S mobile terminal 3.
S12, the outbound gatekeeper 1 attempts to decrypt the ticket voucher information by its stored private key.
And S13, the exit gate 1 controls the gate of the exit gate 1 to open when the ticket voucher information is decrypted successfully.
Illustratively, the private key stored by the outbound gate machine 1 and the public key corresponding to the same outbound point stored by the ticketing center server 2 are a key pair, and the ticket-buying credential information encrypted by the ticketing center server 2 through the public key can only be decrypted by the private key stored by the corresponding outbound gate machine 1. For example, the outbound spot gate 1 may transmit its generated public key to the ticketing center server 2 at idle time, or the outbound spot gate 1 may transmit its generated public key to the ticketing center server 2 and be stored by the ticketing center server 2 at an early stage of establishing a communication connection with the ticketing center server 2. The outbound gate 1 can also update the public key and the private key according to a set update cycle, so that the security of data transmission is further improved under the condition that passengers can normally exit. In urban rail transit, a plurality of gate machines at the same exit station store the same private key, and the private keys in different exit station gate machines 1 are different. Before the exit, the passenger can communicate with the ticket center server 2 through the mobile terminal 3 in advance to obtain the ticket buying voucher information.
It is understood that the Public Key (Public Key) and the Private Key (Private Key) are a Key pair obtained by an encryption algorithm (i.e., a Public Key and a Private Key, i.e., an asymmetric encryption manner). When using a key pair, if one of the keys is used to encrypt a piece of data, only the other key of the key pair can be used to decrypt the data. For example: the data encrypted by the public key must be decrypted by the corresponding private key; if the encryption is performed by the private key, the corresponding public key must be used for decryption, otherwise, the decryption cannot be successfully performed. The public key can encrypt the session and verify the digital signature, and the session data can be decrypted only by using the corresponding private key, so that the security of data transmission is ensured.
In steps S33 and S11, the passenger can use his mobile terminal 3 to send the ticket voucher information stored therein to the gate 1 of the outbound site by means of two-dimensional code, bluetooth, NFC, or the like. When the ticket voucher information is decrypted successfully, the outbound point selected by the passenger when the passenger pays the bus fee is corresponding to the outbound gate 1.
According to the scheme, the private key is stored through the outbound gate 1, the private key is stored by the ticket center server 2, the public key and the private key corresponding to the same outbound point are a key pair, and the ticket center server 2 encrypts ticket-buying voucher information by using the public key corresponding to the outbound point selected by the passenger when the passenger pays the bus fee and sends the encrypted ticket-buying voucher information to the mobile terminal 3 of the passenger. When a passenger sends ticket buying voucher information to the outbound station gate 1 through the mobile terminal 3 of the passenger when the passenger is outbound, the gate is opened and the passenger is allowed to pass as long as the outbound station gate 1 can successfully decrypt the ticket buying voucher information. Therefore, when the passenger leaves the station, the gate machine 1 of the leaving station does not need to communicate with the ticket center server 2, the time for the ticket center server 2 to settle the fee is saved, the burden of the ticket center server 2 is greatly reduced, and the requirement of the passenger for fast leaving the station can be met.
In an alternative embodiment, the ticket voucher information may include fixed information agreed between the gate 1 of the outbound site and the ticket center server 2. For example, the fixed information may be an outbound ID or an outbound name, etc. In the process of attempting to decrypt the ticket-buying voucher information through the private key, if the fixed information in the ticket-buying voucher information is identified to be the same as the fixed information agreed between the ticket center server 2, the outbound gate 1 succeeds in decryption. In this situation, the exit gate 1 does not need to communicate with the ticketing center server 2 when a passenger arrives at the station and arrives at the station, so that the exit gate 1 can ensure that the passenger normally exits even in an off-line state, and the problem that the passenger cannot normally exit in the off-line state of the exit gate 1 is solved.
In another alternative embodiment, the ticket purchase voucher information includes fixed information agreed between the outbound site gate 1 and the ticket center server 2 and random information generated by the ticket center server 2. The random information may be a random code or random information generated in conjunction with the account information and the time stamp of the passenger. In this case, the ticketing center server 2, when transmitting the ticket purchase voucher information to the passenger' S mobile terminal 3 in step S23, further includes: and step S24, sending the random information in the ticket buying voucher information to the out-site gate 1. For example, the ticketing center server 2 can directly send the ticket purchasing voucher information with the fixed information and the random information to the site gate 1, or send only the random information in the ticket purchasing voucher information to the site gate 1.
Thus, the outbound point gate 1 also receives random information from the ticketing centre server 2 and stores it in its database; in the process of attempting to decrypt the ticket-buying voucher information by the private key stored by the outbound gate machine 1, when the fixed information in the ticket-buying voucher information is identified to be the same as the appointed fixed information between the ticket center server 2 and the random information is also inquired in the database of the outbound gate machine, the decryption is successful. Thus, the security of the ticket purchasing voucher information can be improved.
In a preferred implementation of the method provided in the above embodiment, with continued reference to fig. 1, the method may further include:
s14, when the ticket voucher information is decrypted successfully, the outbound gatekeeper 1 further sends a task to the mobile terminal 3 to delete or mark the ticket voucher information stored in the mobile terminal 3 as a disabled state.
S34, the passenger' S mobile terminal 3 also receives a task from the outbound gate 1 to delete or mark the ticket voucher information stored in the mobile terminal 3 as invalid.
Illustratively, if the ticket-buying voucher information sent by the mobile terminal 3 of the passenger to the gate 1 of the given station is inconsistent with the corresponding exit point of the gate 1 of the exit point, the decryption of the ticket-buying voucher information is failed, and at this time, the ticket-buying voucher information stored in the mobile terminal 3 is not deleted or invalidated, and the passenger can continue to use the ticket. The ticket buying voucher information is deleted or invalidated when the decryption is successful, so that the ticket buying voucher information can only be used successfully once. Preferably, in the case that the ticket purchase voucher information includes fixed information and random information, the method further includes: the out-site gate 1, upon successful decryption of the ticket voucher information, also deletes from its database the random information it stored previously from the ticketing centre server 2.
In the scene after the ticket-buying voucher information is successfully decrypted, the random information stored in the gate machine 1 at the outbound point is useless, the data storage burden of the gate machine 1 at the outbound point can be reduced by deleting the random information, the query quantity of the random information in the process of decrypting the ticket-buying voucher information can be reduced by deleting the random information, the passenger can be favorably and quickly decrypted when the passenger is outbound, and the outbound speed of the passenger is ensured.
It should be noted that steps S11 to S14 in the ticket checking method can be individually applied to the exit gate 1 of the rail transit system, as shown in fig. 2. The steps S21 to S24 of the above ticket checking method can be individually applied to the ticket center server 2 of the rail transit system, as shown in fig. 3.
