DETAILED DESCRIPTION OF THE INVENTION
As shown in FIG. 1, it is a schematic diagram of a laptop computer with hardware security protection according to the invention.
The laptop computer with hardware security protection according to the invention includes a host 10, a display 20, an image capture module 30 and a lid 40. The host 10 includes electronic elements such as a motherboard, a central processing unit (CPU), a control chipset and a hard disk therein and can perform operations of electronic data, audiovisual data and so on. An external keyboard 11 is provided for users to input information or instructions. The display 20 is pivotally connected to the host 10 by a pivot 21 provided at the base of the display 20, thereby the display 20 may rotate relative to the host 10 to be open or closed. As shown in FIG. 1, the display 20 is open.
The image capture module 30 is provided on the display 20. As shown in FIG. 1, the image capture module 30 is provided at the top of the display 20 which is the most common position. The image capture module 30 may be certainly provided at other positions of the display 20 but not limited to be at the top of the display 20. The user can operate the image capture module 30 to capture images. Generally speaking, the image capture module 30 is controlled by software without hardware.
The lid 40 is disposed on the display 20 and near the image capture module 30. The lid may slide between a closed position where the lid 40 shields the image capture module 30 and an open position where the lid 40 exposes the image capture module 30. More detailed description is shown as follows according to the following embodiments.
As shown in FIG. 2A and FIG. 2B, they are schematic diagrams showing a lid of a laptop computer with hardware security protection according to the first embodiment of the invention.
The lid 40 is approximately rectangular and provided in a slideway 41. The lid 40 may horizontally slide in the slideway 41 between the far right side and the far left side. The far right side is an open position (as shown in FIG. 2A) where the lid 40 exposes the image capture module 30 and the far left side is a closed position (as shown in FIG. 2B) where the lid 40 shields the image capture module 30.
As shown in FIG. 3A and FIG. 3B, they are schematic diagrams showing a lid of a laptop computer with hardware security protection according to the second embodiment of the invention.
The lid 40 is also design to be rectangular. The lid 40 may vertically slide in the slideway 41 between the upper most side and the lower most side. The upper most side is an open position (as shown in FIG. 3A) where the lid 40 exposes the image capture module 30 and the lower most side is a closed position (as shown in FIG. 3B) where the lid 40 shields the image capture module 30.
As shown in FIG. 4A and FIG. 4B, they are schematic diagrams showing a lid of a laptop computer with hardware security protection according to the third embodiment of the invention.
The shape of the lid 40 may be circular. The lid 40 may rotate between an open position (as shown in FIG. 4A) where the lid 40 exposes the image capture module 30 and a closed position (as shown in FIG. 4B) the lid 40 shields the image capture module 30. The shape of the lid 40 is not limited to the shapes disclosed in the embodiments as long as the lid 40 can move to the open position and the closed position.
As a result, usually, when the lid 40 is at the open position, the image capture module 30 can be normally used. It is provided for a user to operate to capture images, and the images are displayed on the display 20. The lid 40 can be moved to the closed position where the lid 40 shields the image capture module 30. The user can determine whether the image capture module 30 is shielded or not just by the appearance. Even if the image capture module 30 is not switched off or attached by a hacker or hidden spyware etc., the image capture module 30 can only capture the image of the lid 40. Due to the shield of the real lid 40, there is no threat to reveal private images, security protection is increased.
On the other hand, to further ensure the security, the user may be prompted when the image capture module 30 is at the open position. As a result, a trigger switch 50 is provided near the lid 40. As shown in FIG. 2A ̃FIG. 4B, the trigger switch 50 includes a first conductor 51 and a second conductor 52, which are disposed on the display 20 and the lid 40 respectively.
