Description

This invention relates to a file processing system, and more particularly to a confidential file transmission system and method thereof, which achieves both convenient access and confidentiality of data by having the system first send scanned files to the cloud for storage, and then allowing users to access them using a QR code. Generally, common information security issues on the internet need to be resolved through encryption technology. The original owner of a confidential file first encrypts the file before sending it to the recipient. Meanwhile, the original owner of the confidential file sends the file's password to the recipient via another email or other channel. The recipient receives the password, opens the file, and manually enters the password to fully access it. The current system for scanning sensitive files requires scanning the file, adding a password, sending it to the recipient, and then sending the password back to the recipient via another channel to open the encrypted file. If sensitive file scanning is not managed, users may scan sensitive files and save them to their inbox or memory, potentially leading to data theft. In other words, files could be stolen before they are encrypted. On the other hand, passwords that are too short are easily cracked, while those that are too complex are difficult to remember. Therefore, there is a need to provide a confidential file transmission system and method that can overcome the technical shortcomings of conventional systems by sending scanned files to the cloud for storage and allowing users to access them via QR codes, thereby ensuring both data access and confidentiality.
