The ticket code of the electronic ticket is a random number sequence code which can be mapped to a certain electronic ticket uniquely and is used for identifying a certain electronic ticket uniquely. When the user uses the electronic ticket, the user inputs the ticket code of the electronic ticket. Since the electronic ticket is related to the property of the user and the ticket code of the electronic ticket is used to uniquely identify the electronic ticket, a ticket code generation method of the electronic ticket needs to be provided in order to ensure the security of the electronic ticket.

In conjunction with the method for generating a coupon code of an electronic ticket provided in the embodiment shown in fig. 1, fig. 2 provides a method for generating a coupon code of an electronic ticket according to an exemplary embodiment. Referring to fig. 2, a method flow provided by the embodiment of the present invention includes:

201: a globally unique incrementing sequence that was previously assigned to the electronic ticket is obtained.

There is often a certain number and order of electronic coupons for a particular transaction. In order to make the electronic ticket identified by the ticket code unique, it is necessary to provide a number sequence in the security code that makes the electronic ticket unique. Therefore, when the coupon code of the electronic coupon is generated, the uniqueness of the electronic coupon is identified by using the globally unique sequence, and the sequence of the electronic coupon is identified by using the ascending sequence, so that the globally unique ascending sequence which is allocated to the electronic coupon in advance needs to be acquired. By acquiring the globally unique incremental sequence which is allocated to the electronic ticket in advance, the uniqueness of the electronic ticket generated subsequently can be ensured.

For example, if 1000 electronic tickets are to be generated for a certain service, 1000 incrementing sequences are preset, and therefore, when each ticket code is generated, one incrementing sequence is selected from the 1000 preset incrementing sequences as the globally unique incrementing sequence obtained when the ticket code is generated.

202: and acquiring a user identification sequence according to the service account of the user.

In order to ensure the security of the electronic ticket of the user, the user needs to perform a login operation through a corresponding service account before obtaining the electronic ticket, and the service account of the user can often uniquely identify a certain user. In addition, since the number of users may be large, when storing the user information of all users of a certain service, the user information of different users is often stored for the sub-base sub-table, so that the user information of different users is stored in different base tables of different databases. In the embodiment of the present invention, in order to correlate the generated ticket code with the user information of the user, a user identification sequence may be determined according to the service account number of the user, and the user identification sequence is also involved in calculation when the ticket code is generated. The embodiment of the present invention is not particularly limited with respect to a manner of obtaining a user identifier sequence according to a service account of a user. However, in order to confirm the validity of the coupon code later, an association can be established with the database storing the coupon code, and when the user identification sequence is acquired, the number of the base tables established in connection with the service is determined. Thus, the user identification sequence can be used as a user identification or a database identification for storing the generated coupon code.

For example, if the service account of the user is 652358452, and 1000 different library tables are established in advance for the service, when the user information of the user is stored, it is stored in the library table numbered 452, so 452 can be used as the identification sequence of the user obtained according to the service account of the user. Of course, the numerical values herein are merely examples and do not constitute a limitation on the embodiments of the present invention.

203: and acquiring a first random value and a preset first password corresponding to the first random value, wherein each preset password consists of preset numerical digit numbers.

In order to make the generated ticket code more secure, in the embodiment of the present invention, the generation of the ticket code is implemented by using a certain encryption algorithm. In addition, in order to make the generated ticket code have randomness and avoid being easily deduced through the existing ticket code, a random value can be obtained first, and a preset password corresponding to the random value is used for assisting in generating the ticket code. In addition, in order to meet the operation of the encryption process, each preset password consists of preset numerical digits. The embodiment of the present invention is not particularly limited with respect to the specific values of the preset values. For example, each preset password may contain 32 digits, and so on.

The embodiment of the present invention is not limited to a specific manner of obtaining the first random value, and in a specific implementation, a random scrolling manner may be adopted to obtain a value as the first random value. The embodiment of the present invention also does not specifically limit the manner of obtaining the preset first password corresponding to the first random value. It should be noted that, in order to ensure that the first password corresponding to the first random value exists, a mapping relationship between the random value and the password needs to be established in advance.

When the mapping relation between the random value and the password is established, aiming at a certain service, the method can be realized by establishing a service password dictionary containing a preset numerical value strip password. Therefore, when the first password corresponding to the first random value is obtained, the first password corresponding to the first random value may be obtained in a pre-established service password dictionary according to the first random value.

For example, for a certain service, a service password dictionary containing 100 passwords may be established. In addition, the numerical value of the random value may be made to correspond to the number of the password in the service password dictionary. Specifically, if the acquired first random value is 5, the 5 th password may be acquired in the service password dictionary, and the 5 th password may be taken as the first password.

Optionally, since the embodiment of the present invention performs the encryption operation when generating the ticket code. And because the increasing sequence can uniquely identify one electronic ticket, the first random value can ensure the randomness of the security code and the first random value corresponds to the preset first password. In addition, the user identification sequence can identify in which preset database the user information of the user is stored. Therefore, after a first random value is obtained, the first random value and the increment sequence can be combined into the identification of the electronic ticket, and the combined identification of the electronic ticket is stored in a database corresponding to the user identification sequence to be used as a basis for verifying the validity of the electronic ticket subsequently.

The embodiment of the present invention is not particularly limited with respect to the manner in which the first random value and the increasing sequence are combined into the identifier of the electronic ticket. In specific implementation, the first random value can be set to be before, and the increment sequence is after; or setting the delivery sequence to be at the front and the first random value to be at the back; the first random value and the increasing sequence may be sorted in a certain order and then combined, and so on.

For example, if the first random value is 5, the increment sequence is 0000001234, and when the first random value and the increment sequence are combined, the first random value is set to be before and the increment sequence is after, the combined electronic ticket is identified as 50000001234. In addition, the embodiment of the present invention does not limit the manner in which the combined identifier of the electronic ticket is stored in the database corresponding to the user identifier sequence.

The identifier of the electronic ticket combined by the first random value and the increment sequence is stored in the database corresponding to the user identifier sequence, so that the identifier can be inquired in the database corresponding to the user identifier sequence when the validity of the electronic ticket is verified according to the electronic ticket code. In addition, only the identifier of the electronic ticket combined by the first random value and the increment sequence is stored in the database, and the ticket code generated according to the subsequent encryption algorithm is not directly stored, so that even if an illegal user acquires the first random value and the increment sequence from the database, the ticket code cannot be easily deduced, and the security of the electronic ticket can be ensured.

204: and carrying out encryption operation on the first random value, the incremental sequence and the user identification sequence through the first password to obtain the coupon code of the electronic coupon.

The first random value, the increment sequence and the user identification sequence are encrypted by the first password to obtain the coupon code of the electronic coupon in various ways. The specific implementation method comprises but is not limited to the following steps:

the method comprises the following steps: and performing modulo calculation on each digit of the user identification sequence by using each digit at a first preset position in the first password to obtain a first modular value, wherein the digit number of the digit contained at the first preset position is the same as the digit number of the digit contained in the user identification sequence.

The method provided by the embodiment of the invention also participates in the calculation of the user identification sequence when generating the coupon code. Thus, in the encryption process, each digit of the user identification sequence may be modulo by using each digit at a first preset position in the first password. Since the user id sequence may contain multiple digits, in order to implement modulo calculation on the user id sequence, the number of digits contained in the first preset position is required to be the same as the number of digits contained in the user id sequence. For example, if the user identification sequence contains three digits, each digit of the user identification sequence is modulo by using each digit at a first predetermined position in the first password containing three digits. The specific location of the first location is not limited in the embodiment of the present invention, and the first location may be any location pre-specified in the first password. For example, the first to third digits in the first password may be designated in advance as the digits at the first position, and so on.

The embodiment of the present invention is not particularly limited as to the way of modulo each digit of the user identification sequence by using each digit at the first preset position in the first password. In particular, each digit at the first preset position in the first password may be added to each digit of the user identification sequence in a bit-by-bit manner. In addition, in order to ensure the reversibility of the encryption process, when each digit at a first preset position in the first password is added with each digit of the user identification sequence in a bit manner, if the sum of the digit at a certain position in the first password and the digit of the corresponding bit in the user identification sequence is 10, the addition result is used for carrying out modulo operation on 10.

Specifically, when modulo each digit of the user identification sequence is performed by using each digit at a first preset position in the first password, the modulo operation is implemented by, but not limited to, the following formula:

decA＝(key[i]+srcA)％10

the key [ i ] is a certain digit at a first preset position in the first password, the srcA is a certain digit in the user identification sequence, and the decA is a certain digit in a first modulus value obtained by modulo the certain digit in the user identification sequence by using the certain digit at the first preset position in the first password.

For example, if the first password is 32582314256325254784561236985000, the user identification sequence is 452, and the modulo of the user identification sequence using the 5 th digit through the 7 th digit in the first password is pre-specified. Since 32582314256325254784561236985000 digits 5 through 7 are 231, the modulus of 452 is calculated using 231 to obtain 683 the first modulus value.

Step two: and positioning and defining the first modulus value according to the number at the second preset position in the first password to obtain a first positioning sequence.

The positioning definition refers to how to sort a certain sequence, or to which position of an existing sequence a certain sequence is inserted, and so on. In general, the sequence defined by the localization can change the order of the existing sequences. The embodiment of the present invention is not particularly limited with respect to the manner of defining the positioning of the first modulus value according to the number at the second preset position in the first password. The specific position of the second preset position is not specifically limited in the embodiments of the present invention. In specific implementation, the second preset position may also be any position in the first password. For example, the first module value may be defined by selecting the first to third digits of the first code. In combination with the above example, since the number from the first bit to the third bit in 32582314256325254784561236985000 is 325, the first positioning sequence is 325.

Step three: and determining a second random value according to the user identification sequence and the first modulus value, and acquiring a preset second password corresponding to the second random value.

There are many ways to determine the second random value according to the user identification sequence and the first modulus value. For example, the user identification sequence and the first modulus value may be added to determine the second random value, the user identification sequence and the first modulus value may be multiplied to determine the second random value, the user identification sequence and each digit of the first modulus value may be added to determine the second random value, and so on.

Regarding the principle of obtaining the preset second password corresponding to the second random value, the principle is consistent with the principle of obtaining the preset first password corresponding to the first random value in step 203, and specific reference may be made to the contents in step 203, which is not described herein again. For example, if the second random value determined according to the user identification sequence and the first modulus value is 23, a second password corresponding to 23 needs to be acquired.

Step four: and performing modulo calculation on each digit of the incremental sequence by using each digit at a third preset position in the second password to obtain a second modular value, wherein the digit number of the digit included at the third preset position is the same as the digit number of the digit included in the incremental sequence.

The principle of performing modulo calculation on each digit of the incremental sequence by using each digit at the third preset position in the second password is consistent with the principle of performing modulo calculation on each digit of the user identification sequence by using each digit at the first preset position in the first password in the above step, and specific reference may be made to the contents in the above step one, which is not described herein again. The embodiment of the present invention is also not particularly limited with respect to the specific location information of the third preset location in the second password. It should be noted that, in order to successfully use each digit at the third preset position in the second password to perform modulo on each digit of the incremental sequence, it is necessary to ensure that the number of digits included in the third preset position is the same as the number of digits included in the incremental sequence.

For example, if the increment sequence is 0000001234, the second cipher is 01239875123456789054124503218859, and since the increment sequence contains ten bits, ten bits should be selected at a third preset position in the second cipher to modulo the increment sequence. For example, if the digits from the first digit to the tenth digit in the second cipher are selected to modulo the sequence of increments, 0000001234 and 0123987512 may be added bitwise to yield a second modulo value, and thus the second modulo value obtained in this example is 0123988746.

Step five: and positioning and defining the second modulus value according to the number at the fourth preset position in the second password to obtain a second positioning sequence.

The principle of this step is consistent with the principle of the step three in which the first modulus value is defined by positioning according to the number at the second preset position in the first password to obtain the first positioning sequence, which can be specifically referred to the content in the step three, and is not described herein again. The specific location of the fourth preset location in the second password is not specifically limited in the embodiments of the present invention. In specific implementation, any position in the second password can be selected as a fourth preset position. For example, the second bit to the fifth bit in the second password may be selected as the fourth preset position, so that the numbers on the second bit to the fifth bit are used as the second positioning sequence, in this case, the second positioning sequence is 1239, and so on.

Step six: and dispersing the second modulus value according to the second positioning sequence to obtain a first ticket code sequence, dispersing the first modulus value into the first ticket code sequence according to the first positioning sequence to obtain a second ticket code sequence, and taking the second ticket code sequence as a ticket code obtained by performing encryption operation on the electronic ticket.

The embodiment of the present invention is not particularly limited with respect to the manner of discretizing the second modulus value according to the second positioning sequence. In particular, the content determination of the positioning definition can be combined. For example, if the position definition is such that every two digits of the digits are swapped according to the second positioning sequence, then when the second modulus values are discretized, the digits at certain positions in the second modulus values may be swapped for positions. For example, in combination with the above example, if the second module value is 0123988746, the second positioning sequence is 1239, and the positioning definition is to swap the numbers of each two bits corresponding to the second positioning sequence in the second module value when the second module value is discretized, then the numbers of the first and second bits in the second module value are swapped and the numbers of the third and ninth bits are swapped when the second module value is discretized according to 1239, and then the resulting first ticket code sequence is 1043988726.

There may be many ways to discretize the first modulus value into the first ticket sequence according to the first sequence of orientations. For example, the digits on the bits of the first analog value may be inserted into the first coupon code sequence at positions corresponding to the digits in the first positioning sequence, the digits on the bits of the first analog value may be inserted into the first coupon code sequence at positions subsequent to the positions corresponding to the digits in the first positioning sequence, and so on.

When a digit on each bit of the first analog value is inserted into a position next to a position corresponding to a digit in the first positioning sequence in the first ticket code, the manner of discretizing the first analog value into the first ticket code sequence according to the first positioning sequence includes, but is not limited to, the following formula:

Str_new＝Str.substr(0,loc[i])+decA+Str.substr(loc[i])

str _ new is a new sequence inserted into the digit at a certain position in the first modulus, Str. substr (0, loc [ i ]) indicates that the first loc [ i ] position of the first coupon sequence remains unchanged, loc [ i ] indicates the digit at a certain position in the first positioning sequence, decA indicates the digit at a certain position in the first modulus, and Str. substr (loc [ i ]) indicates the digit at a position other than the first loc [ i ] position in the first coupon sequence.

For example, in combination with the above example, if the first token sequence is 1043988726, the first modulus value is 683, the first positioning sequence is 325, and when the first modulus value is discretized into the first token sequence according to the first positioning sequence, the digit on each bit of the first modulus value is inserted one bit after the position corresponding to the digit in the first positioning sequence in the first token sequence, when the second token sequence is generated, the digit 6 on the first bit in the first modulus value is inserted after the digit on the third bit in the first token sequence according to the digit 3 on the first bit of the first positioning sequence 325, so as to obtain the sequence 10463988726; then, the number 8 in the second bit of the first modulus value is inserted 10463988726 after the 2 nd bit number according to the number 2 in the second bit of the first positioning sequence 325, resulting in a sequence 108463988726; finally, the number 3 in the third bit of the first modulus value is inserted 108463988726 after the fifth bit number according to the number 5 in the third bit of the first positioning sequence 325, resulting in the sequence 1084633988726. Thus, the second coupon sequence is 1084633988726.

It should be noted that, when the first modulus value is discretized into the first ticket sequence according to the first positioning sequence, the principle of inserting first and then taking second and then taking first should be followed, that is, when the inserted number is subsequently decrypted, the inserted number is then taken out from the sequence, and when the inserted number is subsequently decrypted, the inserted number is taken out from the sequence first. For example, with reference to the above example, when decrypting the second ticket sequence, the number 3 after the fifth digit of the last insertion is first extracted, the number 8 after the second digit of the current sequence is then extracted in the sequence after the extraction 3, and the number 6 after the third digit of the current sequence is finally extracted in the sequence after the extraction 8.

Optionally, because the database often has a certain version number, in order to avoid data loss after the database has a problem, when the coupon code is generated, the version of the database may be retained, and the version of the database may be inserted into a preset position in the second coupon code sequence, so that the second coupon code sequence inserted into the version number of the database is used as the coupon code of the generated electronic coupon. The specific position of the preset position is not specifically limited in the embodiments of the present invention. In a specific implementation, in order to make the ticket code more random, the preset position may be a position corresponding to the first random value or the second random value, for example, the position may be a position of the first random value or the second random value, or a position of a next bit or positions of the next bits of the first random value or the second random value, and so on.

205: and receiving a coupon code updating request sent by the terminal corresponding to the user identification sequence, returning to the step 203 according to the coupon code updating request until a new coupon code of the electronic coupon is regenerated, and taking the new coupon code as the coupon code of the electronic coupon.

This step is an optional step. In order to ensure the security of the generated ticket code of the electronic ticket identifier, the method provided by the embodiment of the invention supports the real-time update of the ticket code according to the request of the user. For example, the user may initiate a coupon code update request if the user feels his or her coupon code is revealed. In this case, the ticket code update request sent by the terminal corresponding to the user identification sequence may be received, and the process returns to step 203 according to the ticket code update request until a new ticket code of the electronic ticket is generated again, and the new ticket code is used as the ticket code of the electronic ticket. The embodiment of the present invention is not particularly limited with respect to the manner of receiving the ticket code update request sent by the terminal corresponding to the user identification sequence. It should be noted that, since the ascending sequence can uniquely identify the order and number of a ticket code and a service ticket code, the ascending sequence can be kept unchanged when updating the ticket code.

In addition, the ticket code of the electronic ticket generated by the embodiment of the invention is in a digital form, and the digital form ticket code occupies less space compared with the letter form ticket code. In addition, because the card swiping machine usually only supports the ticket code in the digital form, but not the ticket code in the letter form, compared with a scene using letters as the ticket code, the ticket code generated by the method provided by the embodiment of the invention is used as the identifier of the electronic ticket, so that the method is safer and has a wider application range.

Alternatively, after the ticket code of the electronic ticket is generated, the electronic ticket paired with the ticket code can be uniquely identified using the ticket code. At this time, if the user wants to use the electronic ticket, it needs to be realized by the ticket code. Therefore, if it is determined that the user is using the electronic ticket, it is also necessary to determine whether the user can use the electronic ticket. Regarding the manner of determining whether the user can use the electronic ticket, including but not limited to, the following manner:

the first step is as follows: and acquiring a coupon code input by a user when the user uses the electronic coupon, and decrypting the input coupon code to obtain an increasing sequence, a first random value and a user identification sequence corresponding to the input coupon code.

The embodiment of the present invention is not particularly limited as to the manner of obtaining the coupon code input by the user when using the electronic coupon. In specific implementation, a corresponding electronic ticket using page can be provided, and a ticket code input box is set in the page, so that when a ticket code input when a user uses an electronic ticket is obtained, the content input in the preset ticket code input box by the user can be obtained.

The manner in which the input ticket code is decrypted to obtain the incremented sequence, the first random value, and the user identification sequence corresponding to the input ticket code is related to the manner in which the ticket code is encrypted when the ticket code is generated. Specifically, the method of decrypting the input ticket code is an inverse operation of encrypting the ticket code when the ticket code is generated, which may specifically refer to the principle of the encryption method adopted when the ticket code is generated in the first step to the sixth step, and is not described herein again.

The second step is that: and querying a database corresponding to the user identification sequence according to the first random value and the incremental sequence to determine whether the electronic ticket is valid.

In the embodiment of the invention, when the coupon code is generated, the first random sequence and the incremental sequence for generating the coupon code are stored in the database corresponding to the user identification sequence, so that when determining whether the user can use the electronic coupon, the database corresponding to the user identification sequence needs to be inquired according to the first random value and the incremental sequence to determine whether the electronic coupon is effective. And if the first random value and the incremental sequence which are consistent with the first random value and the incremental sequence obtained by decryption are found in the database corresponding to the user identification sequence, determining that the electronic ticket is valid, otherwise, determining that the electronic ticket is invalid.

The third step: if the electronic ticket is determined to be valid, the user is allowed to use the electronic ticket.

Further, after allowing the user to use the electronic ticket, in order to ensure that the user using the electronic ticket is indeed the user himself, the following steps may be included, but not limited to: sending prompt information for using the electronic ticket to the mobile terminal corresponding to the user identification sequence, and determining whether a use confirmation message returned by the mobile terminal is received; and if the confirmation use message returned by the mobile terminal is received, consuming the electronic ticket.

The embodiment of the present invention is not particularly limited as to the manner of sending the prompt information for using the electronic ticket to the mobile terminal corresponding to the user identification sequence. In specific implementation, when the user registers the service account, the number of the mobile terminal corresponding to the user can be reserved, so that when the prompt information for using the electronic ticket is sent to the mobile terminal corresponding to the user identification sequence, the service account of the user can be determined according to the user identification sequence, and the number of the mobile terminal reserved by the user can be inquired according to the service account of the user, so that the prompt information for using the electronic ticket is sent to the mobile terminal corresponding to the user identification sequence. The specific content of the prompt message is not specifically limited in the embodiments of the present invention.

There may be many ways to determine whether an acknowledgment usage message returned by the mobile terminal is received. In specific implementation, the prompt message may carry option information indicating whether the user determines to use, and prompt the user to reply the message according to the option information. For example, the content of the prompt message may be "the electronic ticket with the ticket code of being used ×", and it is confirmed that the use request replies with 1, otherwise, it replies with 0 ". At this time, if the message carrying 1 returned by the mobile terminal is received, it is determined that the use confirmation message returned by the mobile terminal is received, otherwise, it is determined that the use confirmation message returned by the mobile terminal is not received.

In addition, in order to ensure the security of the electronic ticket, when determining whether the confirmation use message returned by the mobile terminal is received, a preset time can be set. And if the confirmation use message returned by the mobile terminal is received within the preset time, determining that the electronic ticket can be consumed. And if the confirmation use message returned by the mobile terminal is not received within the preset time, the user is not allowed to consume the electronic ticket.

There are many ways to consume the electronic ticket, including but not limited to marking the electronic ticket as used, and so on.

By this alternative, the security of the electronic ticket can be better guaranteed by requiring confirmation by the user before consuming the electronic ticket.
