Description

Data sharing method and data sharing system Technical Field The present invention relates to the field of transmission technologies, and in particular, to a data sharing method and a data sharing system. Background With the technological age, various projector systems and meeting reporting systems have been rapidly developed and are also applied to daily life. The meeting reporting system may incorporate a projector system to increase the convenience of the reporter in presenting the material. Most of the current conference report systems are mainly based on wireless communication data transmission. The data transmission mode of wireless communication can be divided into two modes. In the first mode, the computer used by the members participating in the conference must be installed with specific software, and the computer can recognize the devices such as hard disk, universal serial bus (Universal Serial Bus, USB), or compact disk read only memory (CD-ROM). Then, the data in the physical or virtual storage device is transmitted to the screen or display through the wireless network. In the second mode, the computer used by the members participating in the conference can be connected with the transmitting device, and after the transmitting device is connected with the screen or the display through the receiving device, the data in the computer can be put on the screen or the display. In recent years, by conducting conference reports by means of data transmission through wireless communication, the operation efficiency and convenience can be increased. The management of USB transmission ports is one of the items that pay attention to information security, because the data access function of USB is the most frequently occurring information security problem. In the field of information security management, the most efficient and most commonly used way is to turn off the data access function of the USB. In other words, the USB port retains only 5V (volts)/0.5A (amps) and 5V/0.9A power supply functions. However, in a typical computer operating system, when the USB port is connected to the computer, the computer and the USB port communicate via commands (commands) through an ergonomic interface device (Human INTERFACE DEVICE, HID). Then, the computer can identify the hardware specification and data of the USB transmission port. The hardware specification and data of the USB port can be inspected by the device manager interface. However, since the HID command can be transmitted to the computer through the USB port, the security of the HID command is still questioned. In other words, when USB is connected to a computer, there is still a concern and risk of information security because HID commands are considered as an intrusive input signal. Therefore, there is a need to design a new data sharing method and system to overcome the above-mentioned drawbacks.
