The following are detailed below.
Example one
Referring to fig. 1, fig. 1 is a schematic flowchart illustrating a method for starting a two-dimensional code display according to an embodiment of the present invention. The method for starting the two-dimensional code display described in fig. 1 may be applied to a display device and a background server, where the display device establishes a connection with a user terminal based on wireless bluetooth, and the display device communicates with the background server through the user terminal. Further, the screen of the display device is an electronic paper display screen (also called an electronic paper screen or a digital paper screen), and the display device is used for dynamically displaying the two-dimensional code. As shown in fig. 1, the method for starting the two-dimensional code display may include the following steps:
101. and the display equipment sends target parameters to the background server, wherein the target parameters comprise the accumulated updating times of the display equipment and the identification of the display equipment.
In this embodiment of the present invention, the identifier of the display device includes at least one of a serial number identifier of the display device and a graphic identifier of the display device, which is not limited in this embodiment of the present invention.
102. The background server receives the target parameters sent by the display equipment, generates a ciphertext based on the target parameters and the predetermined encryption parameters, and sends the ciphertext parameters to the display equipment, wherein the ciphertext parameters at least comprise the ciphertext.
In the embodiment of the invention, the encryption parameters comprise a predetermined two-dimensional code URL, a predetermined timing time length and a predetermined authentication key. The content contained in the two-dimensional code URL includes content that needs to be promoted to a client, and the two-dimensional code URL is used for a user to jump to link content corresponding to the two-dimensional code URL when scanning the two-dimensional code corresponding to the two-dimensional code URL, so as to obtain a specific resource, for example: advertising content, promotional content, etc.
In this embodiment of the present invention, as an optional implementation manner, the generating, by the background server, a ciphertext based on the target parameter and the predetermined encryption parameter may include:
and the background server generates a ciphertext based on the two-dimension code URL, the target parameter, the timing time length and the authentication key.
Therefore, the optional implementation method can improve the complexity of the ciphertext by generating the ciphertext based on various parameters, and further improve the difficulty of cracking the ciphertext.
In an optional embodiment, the method for starting the display of the two-dimensional code may further include the following steps:
and the background server determines the content type corresponding to the two-dimension code URL, and determines the two-dimension code display duration corresponding to the two-dimension code URL according to the content type, wherein the two-dimension code display duration is used as the predetermined timing time length.
In this optional embodiment, the content type corresponding to the two-dimensional code URL may include any one of a coupon pickup type and a virtual resource reading type. Further, the coupon pickup type may include a first coupon pickup type or a second coupon pickup type. The first coupon getting type is for offline promotion and/or online short-term promotion, and the timing time length corresponding to the first coupon getting type is less than or equal to a certain time length (for example, the timing time length is less than or equal to 10 minutes), for example: the timing time length is 6 minutes, namely the two-dimensional code is refreshed every 6 minutes, namely the effective time length of the two-dimensional code is 6 minutes. Therefore, if the customer needs to get the preference, the customer has to go to the site to scan the code and get the preference, and the function of attracting the customer to the site consumption is achieved. The second coupon getting type aims at long-term online promotion, and the timing time length corresponding to the second coupon getting type is the promotion time length. For example: the content corresponding to the two-dimensional code is an on-line shampoo coupon, the coupon time length of the shampoo coupon is 10 months 1 day to 10 months 10 days, and if the customer A takes the picture of the two-dimensional code, the customer can obtain the shampoo coupon by scanning the picture of the two-dimensional code at any time within the period from 10 months 1 day to 10 months 10 days. Therefore, the online popularization effect can be achieved, and more users can be attracted to online platforms for consumption.
Therefore, the optional embodiment can determine the timing time length for generating the ciphertext according to the content type corresponding to the two-dimensional code URL, and can improve the accuracy and reliability of determining the timing time length.
103. And the display equipment receives the ciphertext parameters sent by the background server and decrypts the ciphertext parameters to obtain the target two-dimensional code URL corresponding to the ciphertext parameters.

the background server generates a first verification code corresponding to the ciphertext based on the encryption parameter, and sends the first verification code to the display equipment;
the display equipment receives a first verification code sent by a background server;
before the display device decrypts the ciphertext, the method for starting the two-dimensional code display may further include the following steps:
the display equipment verifies the first verification code based on the pre-stored check code, and when the first verification code passes verification, the operation of decrypting the ciphertext is triggered and executed.
Therefore, in the optional embodiment, before the ciphertext is decrypted, the verification code corresponding to the ciphertext is generated, and the decryption operation of the ciphertext is executed only after the verification of the verification code is passed, so that the successful decryption possibility of the ciphertext can be improved, the occurrence of time waste caused by the fact that the ciphertext is not required but is decrypted can be reduced, the required ciphertext is decrypted, and the decryption efficiency of the ciphertext is improved.
104. And the display equipment converts the target two-dimensional code URL into a target two-dimensional code image and displays the target two-dimensional code image.
In yet another alternative embodiment, after the step 103 is performed and before the step 104 is performed, the method for starting the two-dimensional code display may further include the following steps:
the display equipment acquires the current accumulated updating times of the display equipment and generates a second verification code corresponding to the identifier of the display equipment and the current accumulated updating times based on the authentication key;
the display equipment updates the target two-dimensional code URL based on the second verification code, the identifier of the display equipment and the current accumulated updating times to obtain an updated target two-dimensional code URL;
as an optional implementation manner, the converting, by the display device, the target two-dimensional code URL into the target two-dimensional code image may include:
and the display equipment converts the updated target two-dimensional code URL into a target two-dimensional code image.
Therefore, in the optional embodiment, after the two-dimension code URL is obtained, the two-dimension code URL is further updated to obtain the updated two-dimension code URL, and only the subsequent two-dimension code image conversion operation is executed, so that the complexity of the two-dimension code URL can be further improved, the difficulty of copying and tampering the two-dimension code image corresponding to the two-dimension code URL is further improved, and the safety and reliability of the two-dimension code information are further improved.
In yet another optional embodiment, after the display device decrypts the ciphertext parameter to obtain the target two-dimensional code URL corresponding to the ciphertext parameter, the method for starting the two-dimensional code display may further include the following steps:
the display equipment judges whether the timing time length corresponding to the target two-dimensional code URL needs to be updated or not;
and when the timing time length corresponding to the target two-dimensional code URL needs to be updated is judged, the display equipment acquires the target timing time length corresponding to the target two-dimensional code URL, updates the target two-dimensional code URL based on the target timing time length, and stores the updated target two-dimensional code URL.
In this alternative embodiment, specifically, the updated target two-dimensional code URL is stored in a memory (also referred to as a security module) of the display device.
Therefore, after the two-dimension code URL is obtained, the optional embodiment further judges whether the timing time length corresponding to the two-dimension code URL needs to be updated, and when the timing time length corresponding to the two-dimension code URL needs to be updated, the accuracy and the reliability of the display time length of the two-dimension code image corresponding to the two-dimension code URL can be improved; and the two-dimension code URL is stored in a memory of the display device, so that the two-dimension code URL can be conveniently and directly acquired from the memory subsequently, the acquisition efficiency of the two-dimension code URL is improved, and the starting efficiency of displaying the two-dimension code image corresponding to the two-dimension code URL is improved.
It can be seen that, by implementing the method for starting the two-dimensional code display described in fig. 1, before starting the two-dimensional code display, information corresponding to a display device for displaying the two-dimensional code is encrypted to obtain an encrypted ciphertext, and the encrypted ciphertext is analyzed to obtain the two-dimensional code URL, so that a two-dimensional code image corresponding to the two-dimensional code URL is displayed, which is beneficial to improving the safety and reliability of the two-dimensional code data, and thus, the possibility that the two-dimensional code information is copied and spread is reduced.
