The following will describe in detail.
Example 1
Referring to fig. 1, fig. 1 is a flow chart of a dynamic update method for two-dimensional codes according to an embodiment of the invention. The dynamic updating method of the two-dimension code described in fig. 1 can be applied to a display device, wherein the display device establishes connection with a user terminal based on wireless bluetooth, and the display device establishes communication with a 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 two dimensions. Still further, the display device may be controlled to dynamically display the two-dimensional code through a user terminal bound to the display device. As shown in fig. 1, the dynamic update method of the two-dimensional code may include the following steps:
101. the display device judges whether the current condition meets a predetermined two-dimensional code updating condition. When the current condition is judged to meet the predetermined two-dimensional code updating condition, triggering and executing step 102; and when the current condition is judged not to meet the predetermined two-dimensional code updating condition, ending the flow.
In the embodiment of the present invention, as an optional implementation of time-based, the display device determining whether the current condition meets the predetermined two-dimensional code update condition may include:
The display equipment acquires the real-time timing duration of the timer of the display equipment and judges whether the real-time timing duration is greater than or equal to the predetermined updating interval duration, wherein the starting time of the real-time timing duration is the last updated time of the two-dimensional code;
when the real-time period is larger than or equal to the update interval time period, the display device determines that the current condition meets the predetermined two-dimensional code update condition.
In this alternative embodiment, the timer of the display device records the real-time display duration of the two-dimensional code currently displayed on the display device as the real-time timing duration of the timer. Therefore, when the real-time display time length of the currently displayed two-dimensional code on the display equipment reaches the predetermined update interval time length, the subsequent dynamic update operation of the two-dimensional code can be conveniently executed in time.
In this alternative embodiment, the predetermined update interval duration may be set by the user of the display device according to actual requirements, for example: the update interval duration of the two-dimension code which the user hopes to update is 2 minutes, namely the user hopes to update the two-dimension code every 2 minutes, and the predetermined update interval duration can also be automatically set by the display equipment according to the content type of the two-dimension code which needs to be displayed, wherein the content type of the two-dimension code can comprise a coupon receiving type. Thus, the update interval duration of the two-dimensional code is determined in various modes, and the determination flexibility of the update interval duration of the two-dimensional code can be improved.
It can be seen that the alternative embodiment can realize the judgment of the update condition of the two-dimensional code by comparing the real-time timing duration of the timer of the display device with the predetermined update interval duration.
In the embodiment of the present invention, as another alternative implementation of time-based, the determining, by the display device, whether the current condition meets the predetermined two-dimensional code update condition may include:
the display device detects whether an update request of the two-dimensional code is received, and when the update request is detected, it is determined that the current condition meets a predetermined two-dimensional code update condition.
In this optional embodiment, the update request of the two-dimensional code may be triggered by the user through the display device, or may be triggered by the user through the user binding with the display device. When the user is closer to the display device, the user can select to trigger the update request of the two-dimensional code on the display device or the user terminal, when the user is farther away, the user can remotely trigger the update request of the two-dimensional code through the user terminal, the triggering possibility of the update request of the two-dimensional code can be improved, the triggering way of the update request of the two-dimensional code is selected according to actual conditions, the triggering flexibility of the update request of the two-dimensional code can be improved, and the experience of the user is improved. Further, the triggering mode of the update request of the two-dimensional code includes at least one of iris triggering, voiceprint triggering and fingerprint triggering, which is not limited in the embodiment of the present invention.
It can be seen that this alternative embodiment can realize the judgement of the update condition of the two-dimensional code by detecting the update request of the two-dimensional code.
In an alternative embodiment, after detecting the update request and before determining that the current condition meets the predetermined two-dimensional code update condition, the dynamic update method of the two-dimensional code may include the following steps:
the display equipment acquires attribute parameters of a trigger triggering the update request of the two-dimensional code, and judges whether the trigger is an authorized user or not according to the attribute parameters;
when the trigger is judged to be an authorized user, the display device triggers and executes the operation of determining that the current condition meets the predetermined two-dimensional code updating condition.
In this alternative embodiment, further, when it is determined that the trigger is not an authorized user, the display device collects image data of the trigger, stores association information between attribute parameters of the trigger and the image data of the trigger, and marks unauthorized users of the trigger. Therefore, when the display equipment fails and/or the content contained in the two-dimensional code on the display equipment is not the required content, the tracking of the unauthorized user of the display equipment and the intelligent function of the display equipment can be enriched according to the related information of the attribute parameters of the trigger and the image data of the trigger.
In this alternative embodiment, the attribute parameter may include at least one of a voice parameter, a voiceprint parameter, a fingerprint parameter, and an iris parameter, and the alternative embodiment is not limited thereto.
Therefore, after the update request of the two-dimension code is detected, the optional embodiment further judges whether the trigger is an authorized user according to the acquired attribute parameter of the trigger triggering the update request of the two-dimension code, and when the trigger is the authorized user, the condition that the update condition of the two-dimension code is met is determined, so that the condition that an illegal user illegally damages the display equipment and/or modifies the content contained in the two-dimension code displayed by the display equipment can be reduced.
102. And the display equipment calculates the target updating total times of the two-dimension code, and calculates the verification code corresponding to the target parameter of the display equipment based on the predetermined authentication key.
In the embodiment of the invention, the target parameter comprises the identification of the display equipment and the total number of target updating times. The identifier of the display device may include any one of a serial number identifier of the display device, a model identifier of the display device, and a graphic identifier of the display device, which is not limited in the embodiment of the present invention. The total number of target updates is equal to 1 increased by the current total number of updates of the two-dimensional code.
In another optional embodiment, the method for dynamically updating the two-dimensional code may include the following steps

the display device obtains two-dimensional code data needed to be borne on the two-dimensional code and an initial authentication key of the display device, performs encryption operation on the two-dimensional code data, the initial authentication key and the second random number based on a predetermined encryption algorithm to obtain encrypted data, and determines the encrypted data as the predetermined authentication key.
In the optional embodiment, the two-dimensional code data can comprise content to be promoted (for example, english training) and a contact way corresponding to the promoted content, wherein the content to be promoted comprises advertisement content and/or preferential content.
In this alternative embodiment, the encryption algorithm may include one or more combination of hash, symmetric and asymmetric encryption algorithms.
It can be seen that the optional embodiment generates the required authentication key based on the random number of the display device, the serial number of the display device, the two-dimensional code data required to be borne on the two-dimensional code and the initial authentication key of the display device, and can generate the unique authentication key, thereby being beneficial to obtaining the verification code of the target parameter of the unique display device subsequently, improving the reliability of dynamic update of the two-dimensional code, improving the safety and reliability of the two-dimensional code data, and further improving the difficulty of copying and falsifying the two-dimensional code data.
103. And the display equipment updates the URL corresponding to the two-dimensional code based on the target parameter of the display equipment and the verification code corresponding to the target parameter to obtain the target URL.
In yet another alternative embodiment, after performing the finishing step 103 and before performing the step 104, the dynamic update method of the two-dimensional code may include the following steps:
the display equipment judges whether the target URL bears all the contents to be displayed or not;
when the target URL is judged to contain all the content, the display device triggers to execute step 104;
when it is judged that the target URL does not contain at least one target content of the entire contents, the display apparatus determines the target content not contained in the target URL based on the entire contents, and re-updates the target URL based on the target content.
In this alternative embodiment, the total content to be displayed may include at least one of advertisement content and preferential content to be displayed. The coupon content may include coupon use time, coupon use limit (for example, 10 yuan of coupons are available every 100 yuan), coupon use range (for example, fresh fruits and vegetables), and store of coupon use, which is not limited in the embodiment of the invention.
In this optional embodiment, as an optional implementation manner, the determining, by the display device, whether the target URL carries all the content to be displayed may include:
the display equipment analyzes the target URL to obtain the bearing content of the target URL, and judges whether the bearing content is the same as all the contents to be displayed;
and when the bearing content is judged to be the same as all the content to be displayed, the display equipment determines whether the target URL bears all the content to be displayed.
Therefore, in the alternative embodiment, the load content of the URL is obtained by analyzing the updated URL, and the load content is compared with all the contents to be displayed, so as to realize the judgment that the URL loads all the contents to be displayed.
Therefore, after updating the URL of the two-dimension code, the optional embodiment further judges whether the updated URL carries all the contents to be carried, so that not only can the URL with high security be obtained, but also all the contents to be displayed/promoted can be ensured to be carried in the URL, and the intelligent function of the display device is further enriched.
104. And the display equipment outputs a target two-dimensional code image corresponding to the target URL.
In an embodiment of the present invention, as an optional implementation manner, the outputting, by the display device, the target two-dimensional code image corresponding to the target URL may include:
the display device converts the target URL into a target two-dimensional code image and outputs the target two-dimensional code image.
It can be seen that this alternative embodiment realizes the output of two-dimensional code image after converting the URL of two-dimensional code into two-dimensional code image.
It can be seen that implementing the dynamic update method of the two-dimensional code described in fig. 1 can determine whether the current condition meets the update condition of the two-dimensional code, and when the current condition meets the update condition, calculate the total update times of the two-dimensional code, update URLs corresponding to the two-dimensional code based on the identification of the display device, the total update times of the two-dimensional code, and the device parameters of the display device, and output two-dimensional code images corresponding to the updated URLs of the two-dimensional code, thereby implementing dynamic update of the two-dimensional code, increasing the copying difficulty of the two-dimensional code, enhancing the security of the original data, and reducing the possibility of decoding the original data and the probability of data leakage, so as to be beneficial to reducing the probability of loss caused by malicious copying, tampering and propagation of the two-dimensional code.
