Addition and decryption interface lock device

The present invention relates to an interface lock device, and particularly relates to a host system with a USB, a memory card and an HDMI interface, which can perform a data encryption and decryption function and an automatic hidden encryption and decryption interface lock device through a hardware interface of a corresponding interface.

Due to the advent of the digital age, especially the popularity of the user's Web3.0 and MicroBlogging and community services, the privacy of personal data and the protection of intellectual property rights have become an important issue to be addressed. And because of the developed information, it makes it easy to obtain and transfer digital content and reproducible data. Digital security management has become very important, and the existing digital file encryption and decryption methods are mostly through exclusive encryption and decryption. Devices (such as: encrypted flash drives, encrypted hard drives, etc.) or through encryption software to achieve its encryption and decryption functions, but these closures, only for specific devices or hosts to achieve encryption and decryption functions, but also in terms of performance The encryption and decryption operations are performed by the host system processor, thereby reducing the overall system operation execution performance, and using the software to perform encryption and decryption, in addition to the above-mentioned related host speed is affected, the program is easily cracked by the side recorder, the entry, the The encryption and decryption file data and the software program for encryption and decryption cannot be automatically hidden after encryption and decryption, and those who are interested can It is easy for the information to be directly and privately or confidentially hacked, and the privacy and confidentiality of the individual or the company are likely to be revealed, thereby infringing on the rights or interests of the individual or the enterprise. The creator takes this point into consideration. Design, the end can be a USB, memory card and HDMI interface host system, through the corresponding encryption and decryption interface lock device to start the encryption and decryption function, and is applicable to a variety of different system platforms, the host-side file data in the transmission process Encryption and decryption and the end of the automatic hiding of the tool program, in line with the needs of progress, practical and user, can see its gain.
