[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0029] The disclosure below provides many different embodiments or examples to realize the different structures of the present application. In order to simplify the disclosure of the present application, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0030] This application provides a method for authorizing the use of a printer. Figure 1 FIG. 1 is a flow chart of an embodiment of the method for authorized use of a printer of the present application. The method may be executed by an electronic device, and the electronic device may be implemented by software and / or hardware. The method for authorized use of a printer includes:

[0031] Step S10: responding to the user's request to use the printer, obtaining the server authorization code to be verified and the printer authorization code to be verified carried in the request;

[0032] Step S20: After decrypting the server authorization code to be verified, the decrypted code is matched with the server authorization code of the pre-generated authorized account to obtain a first matching result;

[0033] Step S30: After decrypting the printer authorization code to be verified, the decrypted code is matched with the printer authorization code of the pre-generated authorization account to obtain a second matching result;

[0034] Step S40: If both the first matching result and the second matching result indicate a successful match, activating and allowing the user to use the printer.

[0035] The printer has multiple functions such as high-speed printing, batch scanning, and print job encryption, and also has multiple software such as document management software, secure printing software, and scanning software. Users can configure corresponding usage periods and permissions for these functions and software, that is, they need to obtain authorization to use these functions or use these software. It can be understood that in this embodiment, the scenario in which the user uses the printer can be the user using the authorized function of the printer, the user using the authorized software of the printer, or the user using the ordinary function of the printer, and no specific limitation is made here. Since in the actual use of the printer, it is possible that the user continues to use the software or function after the authorization expires, the authorization is repeatedly installed and used, or the authorization of different account subjects is mixed, so when the user uses the printer, its authorization status needs to be verified.

[0036] Taking the example of a user using the printer's document printing management software or using an authorized function in the document printing management software, the scheme of this embodiment is explained. The user can input the server authorization code to be verified and the printer authorization code to be verified through the interactive interface of the terminal to initiate a request to use the printer. The terminal responds to the request and obtains the server authorization code to be verified and the printer authorization code to be verified carried in the request. If the server authorization code to be verified passes the verification, the server can be activated. If the printer authorization code to be verified passes the verification, the printer can be activated. After activating the server and the printer, the user can use the printer's document printing management software or use an authorized function in the document printing management software.

[0037] The server authorization code to be verified refers to the authorization code assigned to the user by the server after the user obtains the printer's document management software authorization. The server authorization code is generated by the server's hardware serial number and the relevant information of the authorized account. The printer authorization code to be verified refers to the authorization code assigned to the user by the printer after the user obtains the printer's document management software authorization. The printer authorization code is generated by the printer's hardware serial number, network address and relevant information of the authorized account.

[0038] After decrypting the server authorization code to be verified, the decrypted result includes the server basic code to be verified and the relevant information of the user. The decrypted result is matched with the server authorization code of the pre-generated authorized account to obtain a matching result (recorded as the first matching result). The server authorization code of the authorized account is generated by encrypting the server hardware basic code of the authorized account and the relevant information of the authorized account. If the first matching result indicates a successful match, it means that the server authorization code to be verified has passed the verification, and the server activation is successful at this time. If the first matching result indicates a failed match, it means that the server authorization code to be verified has not passed the verification, and the server activation fails at this time, that is, the user is not allowed to use the printer's printing management software or a certain authorized function in the printing management software.

[0039] After decrypting the printer authorization code to be verified, the decrypted result includes the printer's hardware serial number, network address, and related information of the authorized account. The decrypted result is matched with the pre-generated printer authorization code of the authorized account to obtain a matching result (recorded as the second matching result). The printer authorization code of the authorized account is generated by encrypting the printer's hardware serial number, the printer's network address, and related information of the authorized account. If the second matching result indicates a successful match, it means that the printer authorization code to be verified has passed the verification, and the printer is successfully activated. If the second matching result indicates a failed match, it means that the printer authorization code to be verified has not passed the verification, and the printer activation fails, that is, the user is not allowed to use the printer's document printing management software or a certain authorized function in the document printing management software.

[0040] If both the first matching result and the second matching result indicate a successful match, the server and the printer are activated successfully, and the user is allowed to use the printer's print management software or an authorized function in the print management software. If the first matching result and / or the second matching result indicate that the verification failed, the server and / or the printer fail to activate, and the user is denied to use the printer's print management software or an authorized function in the print management software.

[0041] Since authorization may have a certain period and usage time, when a user needs to use the printer's document management software or use an authorized function in the document management software, by verifying the two authorization codes, the server authorization code to be verified and the printer authorization code to be verified, it can avoid the situation where the user continues to use the authorization after it expires, the authorization is installed and used repeatedly, or the authorization of different account entities is mixed.

[0042] In one embodiment, the process of generating a server authorization code for an authorized account includes:

[0043] Read multiple hardware serial numbers of the server;

[0044] After encrypting each hardware serial number of the server, the encryption results are concatenated to obtain the server hardware basic code of the authorized account;

[0045] Read the relevant information of the authorized account;

[0046] Combining the server hardware basic code of the authorized account with the relevant information of the authorized account to generate a first character string to be encrypted;

[0047] The first character string to be encrypted is encrypted to obtain a server authorization code of the authorized account.

[0048] Read the server's motherboard serial number, CPU serial number, C drive hard disk serial number and other serial numbers, use the MD5 algorithm to encrypt each hardware serial number of the server, obtain the encryption result of each hardware serial number, concatenate the encryption results and convert them into an all-uppercase string as the server hardware base code of the authorized account. Read the relevant information of the authorized account, where the relevant information of the authorized account includes at least one of the authorized use period of the printer, the subject account information, the authorized version number, and the value-added service item information. Combine the server hardware base code of the authorized account with the relevant information of the authorized account to generate a standard JSON string (recorded as the first string to be encrypted), encrypt the first string to be encrypted using the AES algorithm, and obtain the server authorization code of the authorized account.

[0049] Furthermore, the above step of "decrypting the server authorization code to be verified and matching it with the server authorization code of the pre-generated authorized account to obtain a first matching result" specifically includes:

[0050] Decrypting the authorization code of the server to be verified to obtain the decrypted basic code of the server to be verified and relevant information of the user;

[0051] Compare the server basic code to be verified with the server hardware basic code of the authorized account to obtain a first comparison result;

[0052] Comparing the relevant information of the user with the relevant information of the authorized account to obtain a second comparison result;

[0053] If the first comparison result and the second comparison result both indicate that the comparison is consistent, then the first matching result indicates that the match is successful.

[0054] The AES algorithm is used to decrypt the authorization code of the server to be verified, and the decrypted server basic code to be verified and the user's relevant information (including the authorized use period of the printer, the main account information, the authorized version number, and the value-added service item information) are obtained. The decrypted server basic code to be verified is compared with the server hardware basic code of the authorized account to obtain a comparison result (recorded as the first comparison result), wherein the server hardware basic code of the authorized account can also be obtained by re-encrypting multiple hardware serial numbers of the server and splicing them. The relevant information of the user is compared with the relevant information of the authorized account to obtain a comparison result (recorded as the second comparison result). If the first comparison result and the second comparison result both indicate that the comparison is consistent, the first matching result indicates a successful match. After the match is successful, the authorization related information is written, so that the server is activated successfully. If there is an inconsistency between the two comparison results, the first matching result indicates a matching failure. For example, if the relevant information of the user is inconsistent with the relevant information of the authorized account (such as inconsistent authorization period, inconsistent subject account information, etc.), the server cannot be activated at this time, thereby avoiding the situation where the user continues to use the printer after the authorization expires, the authorization is repeatedly installed and used, or different account subjects are authorized to mix and match the printer.

[0055] In one embodiment, the process of generating the printer authorization code of the authorized account includes:

[0056] Read the printer's hardware serial number and network address;

[0057] Read the relevant information of the authorized account;

[0058] Combining the hardware serial number of the printer, the network address and the relevant information of the authorized account based on a preset combination rule to obtain a second character string to be encrypted;

[0059] The second character string to be encrypted is encrypted to obtain a printer authorization code of the authorized account.

[0060] Obtain the printer's motherboard serial number, brand model, MAC address, IP address and other information to generate a labeled JSON string, read the relevant information of the authorized account (including the printer's authorized use period, subject account information, authorized version number, value-added service item information), and combine and splice it into a string to be encrypted (recorded as the second string to be encrypted) according to the following rules:

[0061] [Motherboard serial number @=@Brand model @=@MAC address @=@IP address @=@Authorized use period @=@Subject account information]. It should be noted that the preset combination rule can also be spliced ​​using other characters, and the splicing order can also be changed. The splicing characters and order are not specifically limited here. The second string to be encrypted is encrypted using the AES algorithm to obtain the printer authorization code of the authorized account.

[0062] Furthermore, the above step of "decrypting the authorization code of the printer to be verified and matching it with the printer authorization code of the pre-generated authorized account to obtain a second matching result" specifically includes:

[0063] Decrypting the authorization code of the printer to be verified to obtain the decrypted hardware serial number to be verified, the network address to be verified and relevant information of the user;

[0064] Matching the hardware serial number to be verified with the hardware serial number of the printer;

[0065] Matching the network address to be verified with the network address of the printer;

[0066] Matching the relevant information of the user with the relevant information of the authorized account;

[0067] If both are matched successfully, the second matching result indicates a successful match.

[0068] The AES algorithm is used to decrypt the authorization code of the printer to be verified, and the decrypted hardware serial number to be verified, the network address to be verified and the relevant information of the user are obtained. The decryption result is a plain text regular string. The field information is intercepted by "@=@" to obtain the hardware serial number to be verified, the network address to be verified and the relevant information of the user. The mainboard serial number, brand model, MAC address, IP address, authorized usage period of the user, and the subject account information of the printer to be verified are matched with the corresponding information in the printer authorization code of the authorized account. The matching result is recorded as the second matching result. If all matches are successful, it means that the second matching result indicates a successful match.

[0069] If the hardware serial number to be verified fails to match the hardware serial number of the printer, or the network address to be verified fails to match the network address of the printer, or the relevant information of the user fails to match the relevant information of the authorized account, then the second matching result indicates a matching failure. For example, if the mainboard serial number of the printer fails to match, or the IP address fails to match, or the authorized usage period fails to match, then the printer cannot be activated at this time. This can avoid the situation where the user continues to use the printer after the authorization expires, the authorization is repeatedly installed and used, or different account subjects authorize the mixed use of the printer.
