Description

Screen projection code processing method, screen projection device, electronic equipment and storage medium

Technical Field

The present disclosure relates to the field of computer technologies, and in particular, to a screen projection code processing method, a screen projection apparatus, an electronic device, and a storage medium.

Background

With the continuous development of network technology, people in different areas can carry out video conferences at any time and any place through various electronic terminals. In the process of carrying out the video conference, users participating in the conference may have some information sharing requirements, so that the sharing user in charge of sharing information needs to screen the information file of the sharing user to the video conference device used by the shared user, so that the shared user can see the information file shared by the sharing user based on the video conference device used by the sharing user.

Before a sharing user casts a screen of an information file of the sharing user to a video conference device used by the sharing user, the sharing user generally needs to input a screen casting code on the video conference device used by the sharing user, so that a server casts the screen of the information file to a correct video conference device based on the screen casting code, namely the video conference device used by the sharing user. The screen-projecting code needs to have a globally unique characteristic, and if repeated screen-projecting codes exist at the same time, the server cannot uniquely determine the video conference equipment to be projected after the screen-projecting code is input by the sharing user.

In the prior art, to ensure global uniqueness of a screen-projecting code, a UUID (Universally Unique Identifier) is generally generated in real time, the UUID is used as the screen-projecting code, and if the generated UUID is currently used, the UUID needs to be regenerated. Therefore, in actual use, there may be a case where it is necessary to generate a UUID multiple times, which takes a long time, and there is a case where the same UUID is reused in a short time, increasing the probability of being attacked.

Fig. 1 is a flowchart of a screen-projecting code processing method in the embodiment of the present disclosure. The method can be executed by a screen-projecting code processing device, which can be implemented in software and/or hardware, and can be configured in an electronic device, such as a server.

As shown in fig. 1, the method may specifically include the following steps:

and step 110, responding to a screen projection code application instruction, and determining a target screen projection code from candidate screen projection codes in an idle state.

The screen projection code is an identifier used for determining the screen projected equipment, and a user with screen projection requirements can project contents displayed on a screen of the user terminal to other terminal screens for displaying by inputting the specific screen projection code at the terminal, namely displaying on a display screen of the screen projected equipment, so that the purpose of information sharing is achieved. The screen-projecting code is usually associated with an IP (Internet Protocol) address of the screen-projecting device, and because the IP address is usually complex and is not suitable for a use scene manually input by a user, the IP address is associated with the screen-projecting code, after the user inputs a specific screen-projecting code, the system automatically searches the IP address associated with the screen-projecting code, and then finds the screen-projecting device based on the IP address, so that the screen-projecting purpose is realized. The target screen projection code is a specific screen projection code distributed for the user and used for determining the video conference equipment to be projected. The candidate screen projection codes are screen projection codes which can be allocated to the user as target screen projection codes. The target screen projection code and the candidate screen projection code are both specific screen projection codes. In order to reuse each screen projection code, the screen projection codes are not fixedly associated with a certain IP address but are randomly and dynamically associated, after screen projection is finished, the screen projection codes used at this time can be recycled, and when the same user has the screen projection requirement again, the screen projection codes are regenerated, namely the screen projection codes used when the user projects the screen in each video conference are not necessarily the same, the screen projection codes are generated in real time, the same screen projection codes cannot exist at the same moment, and otherwise, the screen projection equipment cannot be accurately determined. Therefore, the number of screen projection codes is a sea level, so that the screen projection requirements of a large number of users at the same time can be met.

The screen-shot code may be generated from a preset number of characters, which may include at least one of: numbers, letters (including upper and lower case letters), punctuation, or other symbols. For convenience of user input, simplification of complexity of user input and consideration of attractiveness, the screen-projecting code can be composed of similar characters, for example, the screen-projecting code only comprises numbers or letters and the like. In order to meet the requirement of the number of screen-projecting codes, the characters forming the screen-projecting codes can be multiple. In order to fully utilize each character, screen-shot codes as many as possible are generated based on the characters with limited digits, and the screen-shot codes can be generated according to the rules of permutation and combination based on the characters with limited digits. Illustratively, for example, composed of 6-digit capital English letters, the total number of screen-projected codes is 26^6=308915776. In another embodiment, the Chinese character may also consist of 7-digit or 5-digit capital English letters, or 3-digit capital English letters + 3-digit small-case English letters, or 6-digit numbers. In one embodiment, the candidate screen-casting codes in the idle state are stored in a database table, and the storage sequence of the candidate screen-casting codes in the idle state in the database table is different from the initial generation sequence of each candidate screen-casting code, so that the storage sequence of each candidate screen-casting code in the database table is disturbed, and the probability of attacking the screen-casting codes is reduced. The initial generation sequence of each candidate screen-projecting code generated according to the rule of permutation and combination has regularity, such as ACDEFA, ACDEFB, ACDEFC and the like. If the initial generation sequence of each candidate screen-casting code is not disturbed, an attacker can easily calculate the next used screen-casting code based on the currently used screen-casting code, so that the screen-casting code is attacked, the screen-casting error of a user is caused, and the screen-casting information of the user is leaked. In another embodiment, in order to maintain the disorder relation among the candidate screen-casting codes when the target screen-casting codes are restored to the candidate screen-casting codes in the idle state after being used by the user, the candidate screen-casting codes are sorted according to the time when the candidate screen-casting codes are used for the last time, the candidate screen-casting codes are stored in a database table or stored in a queue form based on the sorted order, as shown in fig. 2, a schematic diagram of the candidate screen-casting codes stored in the queue form, an original candidate screen-casting Code generated based on the permutation and combination (the original candidate screen-casting Code refers to an initial candidate screen-casting Code which is not allocated to the user for use) is stored in the queue in a disordered order, the state identifier of each candidate screen-casting Code is marked to be in the idle state, when a screen-casting Code application instruction is received, the candidate screen-casting codes stored at the head of the queue (such as the candidate screen-casting Code1 shown in fig. 2) are determined as the target screen-casting codes, the target screen-casting codes can be supplemented to the tail after the target screen-casting codes are used, and the disorder relation can be maintained, so that the target screen-casting probability of attacks is reduced. In another embodiment, determining a target screen projection code from candidate screen projection codes in an idle state comprises: sorting the candidate screen-casting codes according to the latest used time of the candidate screen-casting codes; and randomly determining target screen projection codes from the sorted candidate screen projection codes.

In order to ensure that only one screen projecting code is the same at the same time, the screen projecting code in use is marked to be in a non-idle state, and when a new screen projecting code is obtained, the screen projecting code is determined from candidate screen projecting codes in the idle state. The screen projection codes in the idle state belong to candidate screen projection codes and can be provided for users to use.

And step 120, changing the state identification of the target screen projection code into a non-idle state.

The state identification of the target screen-projecting code determined to be provided for the user to use is changed into a non-idle state, so that the target screen-projecting code is not repeatedly distributed to other users when other users apply for screen-projecting codes, and the situation that the repeated screen-projecting codes are used at the same time is avoided.

According to the screen projection code processing method provided by the embodiment of the disclosure, when an application instruction of screen projection codes is received, a target screen projection code is determined from candidate screen projection codes in an idle state, and a state identifier of the target screen projection code is changed into a non-idle state, so that when the application instruction of the screen projection codes is received again, the target screen projection code is not distributed to other video conference equipment any more, the application efficiency of the target screen projection code is improved, and the condition that no repeated target screen projection code is used at the same time can be ensured.

Fig. 3 is a flowchart of a screen-shot code processing method in the embodiment of the present disclosure. On the basis of the above embodiments, the screen-projecting code processing method is further optimized in this embodiment, specifically, the following steps are added: and responding to a release instruction of the target screen projection code, and changing the state identifier of the target screen projection code into an idle state. The method has the advantage of realizing the reutilization of the same screen projection code at different moments so as to ensure that the number of the screen projection codes can meet the application requirements of massive users. The same or similar descriptions in this embodiment are not repeated, and reference may be made to the related contents in the above embodiments.

As shown in fig. 3, the screen-projecting code processing method includes the following steps:

and step 310, responding to a screen projection code application instruction, and determining a target screen projection code from candidate screen projection codes in an idle state.

And step 320, changing the state identification of the target screen projection code into a non-idle state.

And step 330, changing the state identifier of the target screen projection code into an idle state in response to the release instruction of the target screen projection code.

When a video conference is finished once, specifically when a user triggers a video conference finishing button or an icon to finish the video conference, triggering a release instruction of the target screen projection code. When the system receives the release instruction, the state identification of the target screen projection code used by the current video conference screen projection is changed into an idle state, so that the target screen projection code is recycled, and the screen projection code quantity can meet the application requirements of a large number of users.

Fig. 4 is a flowchart of a screen-shot code processing method in the embodiment of the present disclosure. On the basis of the above embodiments, the screen-projecting code processing method is further optimized in this embodiment, specifically, the following steps are added: after the state identification of the target screen projection code is changed into an idle state, setting the target screen projection code as a non-candidate screen projection code; and when the time length for setting the target screen projection code as the non-candidate screen projection code reaches a time length threshold value, setting the target screen projection code as the candidate screen projection code. The optimization method has the advantages that the target screen projection code can not be used in a short time, so that the probability that the target screen projection code is attacked is reduced, the screen projection safety of a user is improved, and the risk that user information is leaked is reduced. The same or similar descriptions in this embodiment are not repeated, and reference may be made to the related contents in the above embodiments.

As shown in fig. 4, the method comprises the steps of:

and step 410, responding to a screen projection code application instruction, and determining a target screen projection code from candidate screen projection codes in an idle state.

And step 420, changing the state identifier of the target screen projection code into a non-idle state.

And 430, responding to the release instruction of the target screen projection code, and changing the state identifier of the target screen projection code into an idle state.

And step 440, setting the target screen projection code as a non-candidate screen projection code.

And step 450, when the time length for setting the target screen projection code as the non-candidate screen projection code reaches a time length threshold value, setting the target screen projection code as the candidate screen projection code.

By setting the target screen projection code as the non-candidate screen projection code, the target screen projection code can be guaranteed not to be allocated to a user for use when the screen projection code application instruction is received again, so that the purpose of guaranteeing that the target screen projection code which is just released cannot be reused immediately is achieved, and the probability that the target screen projection code is attacked is reduced. For example, when screen casting codes are distributed to users, target screen casting codes sent to the users are intercepted by hackers, if the target screen casting codes can be reused immediately after being released, when the hackers detect that other users apply for screen casting codes, the target screen casting codes are distributed to other users for use, so that the users cast screens to equipment preset by the hackers, screen casting information of the users is leaked, and the process is a process that the screen casting codes are attacked. When the time length for setting the target screen projection code as the non-candidate screen projection code reaches the time length threshold value, the target screen projection code is set as the candidate screen projection code, so that the target screen projection code is recycled.

Fig. 5 is a flowchart of a screen projection method in an embodiment of the present disclosure. The method can be executed by a screen projection device, which can be implemented in software and/or hardware, and can be configured in an electronic device, such as a server.

As shown in fig. 5, the method comprises the steps of: and step 510, responding to a screen projection instruction, and determining partition information based on a target screen projection code. The screen projection instruction comprises the target screen projection codes, the target screen projection codes are determined from candidate screen projection codes in an idle state, and after the target screen projection codes are determined from the candidate screen projection codes in the idle state, the state identification of the target screen projection codes is changed into a non-idle state.

The screen projection code is used for determining the identifier of the screen projected equipment, and a user with screen projection requirements can project the content displayed on the screen of the user terminal to other terminal screens for displaying by inputting the specific screen projection code at the terminal, namely displaying on the display screen of the screen projected equipment, so that the purpose of information sharing is achieved. The screen-projecting code is usually associated with an IP (Internet Protocol) address of the screen-projecting device, and because the IP address is usually complex and is not suitable for a use scene manually input by a user, the IP address is associated with the screen-projecting code, after the user inputs a specific screen-projecting code, the system automatically searches the IP address associated with the screen-projecting code, and then finds the screen-projecting device based on the IP address, so that the screen-projecting purpose is realized.

The screen-shot code may be generated from a preset number of characters, which may include at least one of: numbers, letters (including upper and lower case letters), punctuation, or other symbols. For convenience of user input, simplification of complexity of user input and consideration of attractiveness, the screen-projecting code can be composed of similar characters, for example, the screen-projecting code only comprises numbers or letters and the like.

In another embodiment, the English letters can also consist of 7-digit or 5-digit capital English letters, or 3-digit capital English letters + 3-digit small capital English letters, or 6-digit numbers, and the like. In one embodiment, the candidate screen-casting codes in the idle state are stored in a database table, and the storage sequence of the candidate screen-casting codes in the idle state in the database table is different from the initial generation sequence of each candidate screen-casting code, so that the storage sequence of each candidate screen-casting code in the database table is disturbed, and the attack probability of the screen-casting codes is reduced.

In another embodiment, determining a target screen projection code from candidate screen projection codes in an idle state comprises: sorting the candidate screen-casting codes according to the latest used time of the candidate screen-casting codes; and randomly determining target screen projection codes from the sorted candidate screen projection codes.

In order to ensure that only one screen projecting code is the same at the same time, the screen projecting code in use is marked to be in a non-idle state, and when a new screen projecting code is obtained, the screen projecting code is determined from candidate screen projecting codes in the idle state. The screen projection codes in the idle state belong to candidate screen projection codes and can be provided for users to use. The state identification of the target screen-projecting code determined to be provided for the user to use is changed into a non-idle state, so that the target screen-projecting code is not repeatedly distributed to other users when other users apply for screen-projecting codes, and the situation that the repeated screen-projecting codes are used at the same time is avoided.

In one embodiment, determining the partition information based on the target screen projection code comprises: converting the target screen projection code into binary digits; determining partition information based on preset digits in the binary digits; and determining partition information according to the partition information. For example, each candidate screen-projecting code is generated by arranging and combining six digits (other digits such as five digits or seven digits) of capital letters (also numbers, lowercase letters, combinations of numbers and uppercase letters, combinations of numbers and lowercase letters, combinations of numbers, uppercase letters and lowercase letters, or combinations of lowercase letters and uppercase letters), one candidate screen-projecting code corresponds to an integer of 26 digits of 6 digits, AAAAAA =0, zzzz zz =308915775, assuming that the target screen-projecting code is OVAZYQ, the corresponding integer is 175330950, the corresponding binary digit is 0000 1010 0111 1100 0101101 1 0100100100100, assuming that partition information is determined based on the lower 14 digits, the corresponding lower 14 digits is 01 0101 0101001 0, and the partition information is 5524, and further determining an ecological domain according to the partition information 5524. An ecological domain is a self-closed software service system which can provide complete functions for users. And (4) isolating resources among different ecological domains, such as storage resources like MySQL and Abase, machine resources and the like. The ecological domain is often used as an identifier of a place where the resource is located, and user or tenant data belongs to a certain ecological domain. If the binary digits of the lower 14 bits are used for determining the partition information, 2^14=16384 partitions can be obtained, and if the binary digits are further increased by 15 bits, the number of screen shots of each partition after combination is about 18855. As shown in fig. 6, each of the candidate screen-casting codes is stored in a queue, and each partition corresponds to a certain number of screen-casting codes. Original candidate screen-casting codes (the original candidate screen-casting codes refer to initial candidate screen-casting codes which are not allocated to a user and used) generated based on permutation and combination are stored in a queue after being scrambled in sequence, the state identification of each candidate screen-casting Code is marked as an idle state, when a screen-casting Code application instruction is received, the candidate screen-casting codes (such as the candidate screen-casting Code1 shown in figure 6) stored at the head of the queue are determined as target screen-casting codes, and the target screen-casting codes are supplemented to the tail of the queue after being used, so that the purpose of keeping the disorder relation among the candidate screen-casting codes can be achieved, and the probability of attacking the screen-casting codes is reduced.

In another embodiment, the determining the partition information based on the target screen-projecting code includes determining the partition information stored in association with the target screen-projecting code based on the target screen-projecting code, that is, the target screen-projecting code and the partition information are two different pieces of information and are stored in different positions respectively. It can be understood that the screen projection codes are converted into binary digits, the preset digits in the binary digits are used for determining the partition information, the purpose of determining the partition information based on the target screen projection codes is achieved, the partition information corresponding to each screen projection code does not need to be additionally stored, the storage space is saved, meanwhile, the searching operation is not needed when the partition information is determined, the determining efficiency and the determining accuracy of the partition information are improved, and the screen projection efficiency and the screen projection accuracy are further improved.

And 520, routing the screen projection instruction to a target end according to the partition information so as to project the current screen information to the target end.

Specifically, routing the screen projection instruction to a target end according to the partition information includes: determining an ecological domain according to the partition information, determining the matched target end from the ecological domain based on the target screen projection code, and routing the screen projection instruction to the target end. An ecological domain is a self-closed software service system which can provide complete functions for users. And (4) isolating resources among different ecological domains, such as storage resources like MySQL and Abase, machine resources and the like. The ecological domain is often used as an identifier of a place where the resource is located, and user or tenant data belongs to a certain ecological domain. After the ecological domain is determined, a corresponding target end is determined based on the target screen projection code, the screen projection instruction is routed to the target end, and the target end can be video conference equipment, so that the purpose of projecting the information of the current screen to the target end is achieved.

In one embodiment, the screen projection method further comprises: and responding to a release instruction of the target screen projection code, and changing the state identifier of the target screen projection code into an idle state. When a video conference is finished once, specifically when a user triggers a video conference finishing button or an icon to finish the video conference, triggering a release instruction of the target screen projection code. When the system receives the release instruction, the state identification of the target screen projection code used by the current video conference screen projection is changed into an idle state, so that the target screen projection code is recycled, and the screen projection code quantity can meet the application requirements of a large number of users.

In one embodiment, the screen projection method further comprises: and after the state identification of the target screen projection code is changed into an idle state, setting the target screen projection code as a non-candidate screen projection code. And when the time length for setting the target screen projection code as the non-candidate screen projection code reaches a time length threshold value, setting the target screen projection code as the candidate screen projection code. By setting the target screen-projecting code as the non-candidate screen-projecting code, the target screen-projecting code can be guaranteed not to be allocated to the user for use when the screen-projecting code application instruction is received again, so that the aim of guaranteeing that the target screen-projecting code which is just released cannot be reused immediately is fulfilled, and the probability that the target screen-projecting code is attacked is reduced. For example, when screen casting codes are distributed to users, target screen casting codes sent to the users are intercepted by hackers, if the target screen casting codes can be reused immediately after being released, when the hackers detect that other users apply for screen casting codes, the target screen casting codes are distributed to other users for use, so that the users cast screens to equipment preset by the hackers, screen casting information of the users is leaked, and the process is a process that the screen casting codes are attacked. When the time length for setting the target screen projection code as the non-candidate screen projection code reaches the time length threshold value, the target screen projection code is set as the candidate screen projection code, so that the target screen projection code is recycled.
