Problems solved by technology
However, fingerprint booting will also bring some problems
First of all, in the off state, fingerprint verification needs to consume a lot of power, which will seriously affect the standby time of the battery for computers such as notebook computers; secondly, the fingerprint detection method needs to increase fingerprint detection and verification devices, and the cost is relatively expensive

Embodiment Construction
[0045] For a computer system, in the process of starting each computer, the power-on process is indispensable, and it is a very critical step in the process of starting the computer. Starting from triggering the power-on button, each signal of the power-on sequence is closely related to other signals, and the time interval between them is also fixed, as long as one of the signals cannot be generated or the time interval between other signals does not match. If the specified power-on requirements are not met, the entire machine cannot be powered on normally. It can be seen that the generation of power-on sequence is the most critical link in the power-on process.
[0046] For this reason, the idea of the present invention is to provide system security by providing an external power-on sequence control device, and the embedded controller built in the computer authenticates the external power-on sequence control device when starting up. After passing the authentication, the em...

This invention discloses an upper electricity sequence control device supplying the upper electricity sequence for the computer system which concludes the first interface, authentication information delivery module, upper electricity sequence delivery module and the first power module. Among of them, the first interface connects with the computer system in order to mutual with the computer system; the authentication information delivery module is used to response the send authentication request by the computer system through the first interface and then it make the authentication information of the device delivered to the computer system by the first interface; the upper electricity sequence delivery module is used to receive the send upper electricity sequence request by computer system through the first interface and response the upper electricity sequence request and then send the upper electricity sequence request to the computer system through the first interface; the first power module is used to offer the power for the authentication information delivery module and the upper electricity sequence delivery module. This invention also discloses a computer system, the upper electricity system of computer system and the upper electricity method of it. The device and the system power consumption of this invention are small, the easy manufactory, the low cost, and the good security.
Description
technical field [0001] The invention relates to computer system security technology, in particular to a power-on sequence control device, a computer system, a power-on control system and a method thereof. Background technique [0002] With the popularity of computer applications, the security of computer systems has attracted more and more attention from users. The security setting solution in the prior art is mainly realized by setting a power-on password. For example, it may be implemented by setting a power-on password of the system under a Basic Input / Output System (BIOS for short). After the system is turned on, it will perform the BIOS power-on self-test, and then enter the DOS screen. At this time, it is necessary to enter the preset password and pass the verification before it can be turned on and enter the computer's operating system. This method has been used for a long time to ensure the security of computers and the privacy of user data to a certain extent. How...
