3), graphic code presentation device according to setting the period to server send off-line graphical code acquisition request, in this way whenever When interval duration between at the time of current and at the time of last time sends off-line graphical code acquisition request reaches the above-mentioned setting period, Then graphic code presentation device sends off-line graphical code acquisition request from trend server.

Certainly, it is only exemplary herein and lists several triggering graphic code presentation devices to server transmission off-line graphical The specific triggering mode of code acquisition request, in addition to this it is possible to trigger graphic code presentation device by other means to service Device sends off-line graphical code acquisition request, and this specification embodiment will not enumerate.

It should be noted that mentioned in this specification embodiment to off-line graphical code then refer to offline generate, with And the double off-line graphical codes verified by barcode scanning equipment off-line.

Step 104, the configuration information of the off-line graphical code based on above-mentioned user, it is raw according to the generating random number rule of setting At the different random number of specified quantity；Wherein, above-mentioned configuration information is used to indicate the off-line graphical code for needing to generate Number, and the quantity of random number is equal with the number of off-line graphical code that needs generate.

In order to enable having differences between each off-line graphical code corresponding to the same user generated, need to be directed to Each off-line graphical code generates a random number, and random number corresponding to each off-line graphical code is different.

Specifically, server every time when generating off-line graphical code, generally can all generate multiple off-line graphical codes, need to protect It is different to demonstrate,prove each random number corresponding to the off-line graphical code generated every time, it is also necessary to guarantee generating off-line graphical every time It is required to generate different random numbers when code.It can just guarantee that the off-line graphical code generated every time is all different in this way, and every time The each off-line graphical code generated is also different.

In a specific embodiment, it can be used at the time of receiving off-line graphical code acquisition request every time or life At prefix at the time of random number as random number, it can guarantee that the random number generated every time is different in this way.Certainly, in life It, can be according to needing the quantity of the off-line graphical code generated to be encoded every time, as the specific interior of random number when at random number Hold, can guarantee that the multiple random numbers generated every time are different in this way.It is generated random i.e. in this specification embodiment Number includes prefix and particular content.This ensure that the random number generated every time and every time is different, and generate every time Multiple random numbers are different.For ease of understanding, following to be illustrated citing.

For example, in a specific embodiment, server 05 tap at 12 days 13 December in 2018 receives graphic code The off-line graphical code acquisition request that presentation device is sent, and this is determined according to the configuration information of acquired off-line graphical code It is secondary to need to generate three off-line graphical codes, in generating the secondary off-line graphical code when random number corresponding to each off-line graphical code, 201812121305 prefix as this random number generated at the time of can receiving off-line graphical code acquisition request, When determining the particular content of each off-line graphical code, due to needing to generate three off-line graphical codes, it can be used 1,2,3 in this way Individual digit encoded, also can be used 11,12,13 as dibit number encode etc., as long as guaranteeing to be compiled Each number of code is all different, and is then added to obtained coding behind above-mentioned prefix as particular content, from And each random number corresponding to the off-line graphical code that the secondary needs generate is obtained, random number generated can be 20181212130511,20181212130512 and 20181212130513.

Certainly, in addition to this it is possible to generate above-mentioned random number based on other generating random number rules, as long as guaranteeing every The secondary and random number generated every time and each random number generated every time are all different.Above-mentioned only exemplary illustration, The restriction to this specification embodiment is not constituted.

Step 106, for each random number, the letter of user corresponding to the identification information to above-mentioned random number and above-mentioned user Breath carries out signature processing, and the signing messages that signature is handled is as the code value of off-line graphical code；Wherein, the code value is for giving birth to At off-line graphical code.

Specifically, being stored with user information corresponding to each user in the server, therefore, off-line graphical can be based on The identification information of entrained user searches user information corresponding to the user in code acquisition request.Wherein, above-mentioned user's letter Registration information when breath can be registered on the server for user, for example, the name of user, age, identification card number, Number, identity information etc..

In above-mentioned steps 106, signature processing is carried out to random number and user information, actually uses mechanism (figure Code issuing organization) private key encrypts random number and user information, obtained signing messages is a string of character strings, as from The code value of line chart shape code, the corresponding off-line graphical code of a code value.

It in the specific implementation, can be using the mechanism private key stored in server to random number and use in above-mentioned steps 106 User information corresponding to the identification information at family carries out signature processing.The server is then the corresponding service of graphic code issuing organization Device, correspondingly, said mechanism private key is then the private key of graphic code issuing organization.

In the bright book embodiment of this book, after the code value that off-line graphical code is generated by server, which is handed down to figure Code presentation device then generates corresponding offline figure based on the code value when graphic code presentation device needs to show off-line graphical code Shape code.

For ease of understanding, following to be illustrated citing.

For example, in a specific embodiment, the server of above-mentioned generation off-line graphical code is a kind of payment server, It receives in the off-line graphical code acquisition request of graphic code presentation device transmission and carries the identification information for being user A, therefore, need Off-line graphical code corresponding to user A is generated, according to the configuration information of accessed off-line graphical code, determines that this time needs The quantity for the off-line graphical code to be generated is three, is denoted as off-line graphical code 1, off-line graphical code 2 and off-line graphical code 3 respectively, Three random numbers generated are denoted as random number 1, random number 2 and random number 3 respectively, and the user information of acquired user A is User information A, therefore, when generating off-line graphical code, respectively using payment mechanism private key to user information A+ random number 1 into Row signature, obtains code value corresponding to off-line graphical code 1, is carried out using the private key of payment mechanism to user information A+ random number 2 Signature, is obtained code value corresponding to off-line graphical code 2, is signed using the private key of payment mechanism to user information A+ random number 3 Name, obtains code value corresponding to off-line graphical code 3.

The generation method for the off-line graphical code that this specification embodiment provides generates off-line graphical code in server end, by It is stored in mechanism private key in server end, therefore, when generating off-line graphical code, can directly use mechanism private key It signs to user information and random number；It only needs to carry out once signed to user information and random number using mechanism private key Code value corresponding to off-line graphical code can be generated；With in the prior art client generate off-line graphical code compared with, be not required to It reuses private key for user and once signed is carried out to random number, therefore need not also carry client public key in code value generated, The generating process of off-line graphical code is simplified, the code value length of off-line graphical code generated is also shortened, to reduce Requirement to barcode scanning equipment consumes the recognition success rate of graphic code, shortening identification correspondingly, certain barcode scanning equipment can be improved When.

In the specific implementation, in order to determine the number of random number that needs generate, before executing above-mentioned steps 104, also Need to obtain the configuration information of off-line graphical code, in a specific embodiment, can obtain as follows it is above-mentioned from The configuration information of line chart shape code:

Step 1: use information of the user to off-line graphical code in acquisition setting time length；Wherein, above-mentioned use information User is used to indicate to the frequency of use of off-line graphical code；

Step 2: the term of validity information based on above-mentioned use information and off-line graphical code, determines what current needs generated The number of off-line graphical code, as above-mentioned configuration information.

Due to user in different phase to the use demand of off-line graphical code there may be difference, generating every time When off-line graphical code, for the service condition information to off-line graphical code in available nearest a period of time.It is being embodied When, available user in nearest one week to the use information etc. of off-line graphical code, above-mentioned setting time length it is specific Setting can be configured according to practical application scene, and this specification embodiment is defined not to this.

Above-mentioned use information can for user in the setting time length to the usage record information of off-line graphical code, example Such as, which can be with are as follows: 21 user is divided to pay using off-line graphical code when 21 days 13 December in 2018, December 21 in 2018 05 user is divided to pay using off-line graphical code when days 14,22 days 09 December in 2018 when 08 user is divided to use off-line graphical code It pays etc..

In this way, can determine that user is long in setting time based on the use information after getting above-mentioned use information It spends the interior demand number to off-line graphical code and user uses the letter such as frequency of off-line graphical code in the setting time length Breath.

In order to ensure the safety of user information, the code value of general off-line graphical code is not suitable for placing the long time, therefore, It needs that a safe and effective time limit is arranged for the code value of each off-line graphical code, when the generation time of the code value of the off-line graphical code After the safe and effective time limit, then the code value of the off-line graphical code is invalid.Therefore, user is being got to off-line graphical code After use information, it is also necessary in conjunction with the term of validity information of the code value of off-line graphical code, determine the off-line graphical code for needing to generate Number.

For example, in a specific embodiment, determine that user has probably used 10 off-line graphical codes in the last week, An off-line graphical code is used within i.e. average user one day, and the term of validity of the code value of each off-line graphical code is three days, therefore, After the off-line graphical code acquisition request for receiving the transmission of graphic code presentation device, 5 off-line graphical codes can be generated for user.
