Problems solved by technology

[0002] In order to protect business secrets in commercial information equipment and information systems, enterprises need to restrict data export, but data import is frequently required in daily business. Importing information from an SD card to a PC is a typical requirement, but common The SD card only has the two-way function of output and input. Whether the data can be exported depends on the holder of the SD card, and it cannot effectively prevent the export of trade secrets from the PC.
