Latest Patents
One of his latest inventions is the "Cloud Door Lock Control System with Identification of Time Varied 2D Codes and Images." This system identifies time varied 2D codes and images to control door locks via a cloud device. The device transmits encryption codes for doors, time periods for opening them, and user encryption codes to a mobile phone. The mobile phone stores these values in memory, and an app encrypts them using a specific code. The encoding method is time varied, meaning the QR code is only valid for a preset time period. After this period, a new QR code is generated. When the cloud device receives a QR code from a card reader, it decodes it and compares the data with what is stored in the cloud to determine if the door should be opened.
Another patent by Cheung is the "Cloud Door Lock Control System with Identification of Time Varied 2D Codes." Similar to the previous invention, this system also transmits encryption codes and utilizes a mobile app for secure access. The innovative aspect lies in the time-sensitive nature of the QR codes, ensuring enhanced security.
