Method, server, and system for providing customized products by decoding security-processed QR codes

摘要

The method performed by the decryption server to provide the customized product by decrypting the security-processed QR code is an encrypted version generated by performing the primary decryption of the security-processed QR code by the client. Receiving a service request from the client including the server-side message and the client identification information, extracting the service information by secondary decoding the server-side message, and performing the security processing on the client based on the service information. Determining whether or not a condition set in advance for the QR code is satisfied. [Selection diagram] Fig. 1
