Abstract

The invention includes USB interface, USB interface controller, MCU processor, MEMS driver for micro motor, and MEMS information security strengthened chain. USB interface is connected to the USB interface controller, which is connected to MCU processor. Output of the MCU processor is connected to MEMS driver, whose output is connected to MEMS strengthened chain. MCU processor receives data signal forwarded by computer from USB interface controller, and decrypts the signal and outputs it to MEMS driver for micro motor. Output of the MEMS driver drives MEMS information security strengthened chain. The invention manages and controls safe starting for computer, and prevents computer from illegal use. Advantages are: computer hardware resources are not opened completely; the said strengthened chain restricts computer resources from use by illegal users; it is convenient to use through USB interface; it is useful for dedicated organizations to manage computers.

Description

technical field [0001] The invention relates to a device in the field of information technology, in particular to a computer lock based on a micro-electro-mechanical system information security strong chain. technical background [0002] With the widespread popularity of computers and the Internet in recent years, many users store private letters, personal photos, emails, credit card numbers, passbook passwords and other personal privacy information, as well as important business data such as government documents, business secrets, and technical secrets. In the computer, how to protect the stored information from being illegally obtained, embezzled, tampered with and destroyed, and to ensure data security has become the most concerned and urgent problem in the current IT industry. At present, the highest level of controlling the use of computers is to use the operating system's identification system to restrict illegal users from entering the operating system. Obviously, it ...
