Description

Technical Field

[0001] This disclosure relates to the field of computer technology, and in particular to a method, apparatus, device and computer-readable storage medium for generating training certificates. Background Technology

[0002] Following typical social training programs, certificates are awarded to participants. These certificates usually include the participant's name, photo, training content, and the training institution's seal. The certificate issuance process typically involves the training organizer arranging for staff to collect participant photos. This collection can be done either by participants preparing photos in advance or by having photos taken on-site. The photos are then processed, the certificates are printed, and the certificates are matched with the participants' photos. The photos are then pasted onto the corresponding participants' certificates, and the official seal is affixed. Finally, the certificate content is verified, and the certificates are either distributed to participants on-site or mailed to their designated addresses.

[0003] Therefore, it is evident that the collection and verification of photo information, the matching of photo information with certificate information, and the production, stamping, and distribution of certificates all require significant manpower and time. This is especially true for short-term training programs with a large number of participants. Manually completing the certificate production and verification processes results in even lower certificate issuance efficiency, often requiring certificates to be mailed to trainees after the training, which undoubtedly further increases the manpower and mailing costs. Furthermore, manually matching photos and certificates, producing and distributing certificates under high-intensity and high-pressure work conditions is prone to errors, leading to problems such as incorrect photo pasting, low efficiency, and incorrect mailing.

[0060] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0061] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0062] Existing training certificate generation solutions require significant manpower and time for processes such as collecting and verifying photo information, matching photo information with certificate information, certificate production, stamping, and distribution. This is especially true for short-term training programs with a large number of participants. Manually completing the certificate production and verification processes further reduces efficiency, often requiring certificates to be mailed to trainees after training, which undoubtedly increases labor and mailing costs. Furthermore, manually matching photos and certificates, producing and distributing them under high-intensity and high-pressure conditions is prone to errors, leading to problems such as incorrect photo pasting, low efficiency, and mailing errors.

[0063] To address this issue, this disclosure provides a method for generating training certificates, which will be described below with reference to specific embodiments.

[0064] Figure 1 This is a flowchart illustrating a training certificate generation method provided in this embodiment. This method can be applied to electronic devices and to scenarios involving the generation of training certificates. It effectively solves problems related to the workflow of training certificate processing, difficulties in collecting, organizing, and classifying certificate photos, errors due to manual processing, long waiting times for paper certificates, and low communication efficiency. It also addresses a series of problems inherent in traditional paper certificate generation, such as high costs associated with manual labor, production, and mailing, low efficiency, poor information accuracy, difficulties in verification, inability to permanently store certificates, and the inability to create electronic training archives. It is understood that the training certificate generation method provided in this embodiment can also be applied to other scenarios.

[0065] The following is combined with Figure 2 The working principle flowchart, for Figure 1 The training certificate generation method shown here is introduced. The method includes the following steps:

[0066] S101. Manage the entire training process and collect key data, including training sessions, trainees for each training session, courses taught, attendance, teaching location, instructors, and evaluation results.

[0067] like Figure 2 As shown, training organizers can log into the training management system, and the electronic devices can manage the entire training process and collect key data. This key data includes training sessions, participants for each session, courses taught, attendance records, teaching locations, instructors, and assessment results. Specifically, the electronic devices manage the entire training process and collect key data through the training process module.

[0068] S102. In response to the selection operation of the training organizer, determine the academic management data of the target training class from the key data. The academic management data of the target training class includes at least the certificate type, courses taught, course attendance, assessment results, and actual trainees of the target training class.

[0069] The training organizer selects key data, and the electronic device responds to this selection by determining the academic management data for the target training course from the key data. This academic management data includes at least the certificate type, courses taught, course attendance, assessment results, and actual trainees for the target training course. Specifically, the academic management data for the target training course is determined from the key data through the electronic training certificate application module.

[0070] S103. Based on the academic management data of the target training courses, generate electronic certificates for the training in batches.

[0071] The electronic device generates electronic training certificates in batches based on the academic management data of the target training courses. Specifically, the academic management data of the target training courses is sent to the electronic training certificate generation module, which then generates electronic training certificates in batches.

[0072] S104. Upload the electronic certificate to the training student system application server.

[0073] The electronic device uploads the electronic certificate to the training student system application server. Specifically, the training electronic certificate data is synchronized to the training student system application server through the training electronic certificate publishing module.

[0074] S105. In response to the login operation of the trainee, obtain the trainee's identity identifier, and obtain the corresponding training electronic certificate download address based on the identity identifier, so that the trainee can download their respective PDF electronic certificate documents through the download address during or after the training.

[0075] The electronic device responds to the trainee's login operation by obtaining the trainee's identity identifier and, based on the identifier, obtaining the corresponding download address for the training e-certificate. This allows the trainee to download their respective PDF e-certificate document via the download address during or after the training. Specifically, the electronic certificate authentication module obtains the trainee's identity identifier and, based on the identifier, obtains the corresponding download address for the training e-certificate, allowing the trainee to download their respective PDF e-certificate document via the download address during or after the training.

[0076] In some embodiments, the electronic certificate authentication module of the electronic device verifies the identity of the file opener based on the certificate private key entered by the student during login and the server public key, and controls PDF file operation permissions and determines file legitimacy based on the access policy provided by the HEADER area information of the PDF electronic certificate. Based on the document opener's identity, the number of authentication attempts is recorded and returned to the certificate log management storage.

[0077] Table 1 compares the training courses grouped by a sample of 200 training courses. The training courses using this certificate generation method show significantly improved efficiency, higher student satisfaction, and can greatly reduce the time costs of communication and manual sorting. It can also reduce the economic costs of printing, transporting, and mailing a large number of training certificates, thus having good social and economic benefits.

[0078] Table 1. Comparison of the effects before and after the application of the training course for 200 people.

[0079]

[0080]

[0081] Based on the comparison in Table 1, the traditional method takes 17 hours to complete when 200 people register together. It generally requires one organizer to complete the process in 2-3 working days, with a basic cost of 3,000-5,000 yuan, mainly for certificate production and mailing costs. The training certificate generation method takes only 12 minutes, generally requires no manual intervention, has zero cost, and is 100% accurate.

[0082] Compared to existing technologies, the training certificate generation method disclosed herein has the following advantages:

[0083] This disclosure manages the entire training administration process, collects key data, responds to the training organizer's selection operations, determines the administration data for the target training courses from the key data, and generates electronic training certificates in batches based on the administration data of the target training courses. The electronic certificates are then uploaded to the training student system application server. This effectively solves problems related to the business processing flow of training certificates, difficulties in collecting, organizing, and classifying certificate photos, errors due to manual processing, long waiting times for paper certificates, and low communication efficiency. It also addresses a series of problems associated with traditional paper certificate generation, such as high costs for manual labor, production, and mailing, low efficiency, poor information accuracy, difficulty in verification, inability to permanently store certificates, and inability to create electronic training archives. This has profound significance and impact on improving the brand benefits of training institutions and enhancing the overall image and informatization level of the training industry.

It also addresses a series of issues inherent in traditional paper certificate generation, such as high costs for manual labor, production, and mailing, low efficiency, poor information accuracy, difficulties in verification, inability to permanently store certificates, and the inability to create electronic training archives. This has profound significance and impact on improving the brand image of training institutions and enhancing the overall image and informatization level of the training industry.
