Description

The present invention locks the screen of a webcam mounted on or attached to a personal computer, mobile terminal, or information communication terminal with a single touch on a cover that optically closes the lens and acoustically closes the microphone to protect privacy. It is related to the eavesdropping prevention cover for webcams, which has a button to put it in a state.

As a webcam cover of this type, a voyeurism prevention cover for a webcam according to the proposal of the present applicant is known (Patent Document 1).

The screen lock function of the personal computer is a function built into the operation system, and it is excellent in power saving during standby by putting the screen of the personal computer in hibernation, and unlike shutdown, recovery from hibernation is quick. Furthermore, by setting the password lock that is also built into the operation system, it is possible to prohibit other people from operating during hibernation by requesting a password when returning from hibernation, resulting in high security. Be done.

There are several ways to lock your computer screen. Taking Microsoft's Windows as an example, the start icon → user icon → lock is an example. An example is to enter the Windows key + L from the keyboard. In the setting panel, it is set to lock the screen in advance for a certain period of time.

The known anti-voyeur cover for webcams mentioned in the above background technology has gained popularity because it optically closes the lens, is effective against software risks such as webcam hijacking, and is easy to introduce. However, it is only a single function to prevent peeping and voyeurism, and has no effect on eavesdropping of voice.

The screen lock function of a personal computer is excellent in power saving and is used in many places due to its high security combined with authentication settings such as passwords, and it is often strict rules depending on the usage environment of the personal computer. However, it is not without problems.

Taking Microsoft's Windows screen lock method illustrated in the above background technology as an example, the former two cases require multiple steps using a mouse or keyboard, and the user bends down when standing up. You have to operate the mouse or keyboard. If the screen is automatically locked after a certain period of time, a power saving effect can be recognized depending on the set time, but there is a problem with security when leaving the front of the personal computer.

By setting the mounting position of the present invention on the lens 9 of the webcam of the personal computer, the lens is optically closed and functions as a peep voyeur prevention cover for the webcam.

By providing a pad 6 made of a material having excellent sound insulation at a position where the microphone 10 of the webcam of the personal computer comes into contact with the present invention, the microphone is acoustically closed and functions as an eavesdropping prevention cover for the webcam.

Further, the push button 2 of the present invention generates a signal corresponding to a shortcut key for screen lock by passing through the MCU (Micro Control Unit) 4, and puts the personal computer in the screen lock state with one touch.

Since the main body of the present invention functions as a cover for preventing eavesdropping on a webcam, it is effective in avoiding privacy risks such as taking over the webcam by optically blocking the lens 9 and acoustically the microphone 10.

Since the push button 2 is located on the front of the personal computer, the screen lock function can be easily used by being within reach regardless of whether the user is standing or sitting, and it is customary for the user to lock the screen diligently. It becomes an incentive to attach, and you can enjoy power saving effect and high security.

The "personal computer" according to the present invention corresponds to a computer, a mobile terminal, an information communication terminal, or the like equipped with or externally equipped with a display and a webcam.

The "screen lock function" according to the present invention includes a screen lock function, a screen saver function, a sleep function, and the like that restrict the operation of a personal computer with an authentication setting such as a password built into the operation system.

The ease of locking the screen of a personal computer according to the present invention produces a power saving effect and high security. The practice of hiding the lens and microphone when the webcam is not in use reduces the potential risks to the webcam, such as voyeurism and eavesdropping that abuses the webcam, as well as fraudulent scams. Industrial applicability is high.

It is the figure when it was seen from the front in the state which covered the lens and the microphone by this invention when the webcam of a personal computer was not used. It is a figure when the present invention is moved sideways to expose a lens and a microphone, and is seen from the front when using the webcam of the personal computer. FIG. 1 is a view of FIG. 1 viewed from above with the lens and microphone covered by the present invention when the webcam of a personal computer is not used. FIG. 2 is a view of FIG. 2 viewed from above with the present invention moved sideways to expose the lens and microphone when using a webcam of a personal computer. It is a figure when the present invention is viewed from the side. It is a figure when the present invention is seen from the back (the back of a personal computer). It is a figure when the personal computer when this invention is installed in the personal computer is seen from the front. As an example of the implementation of the screen lock function of the present invention, it is a circuit diagram of an example in which Pro Micro (Arduino compatible general-purpose microcomputer board) is used for the MCU and USB is used for the wiring for transmitting the key information of the screen lock to the computer.

Hereinafter, description will be given based on examples of the present invention.

The base component 1 has a strength that does not impair the function of the push button 2 and can withstand movement when the webcam 9 of the personal computer is used.

The base component 1 has enough weight and elasticity to bring the pad 6 that closes the microphone of the webcam into close contact with the microphone for the purpose of sound insulation.

The base component 1 has an appropriate amount of play so that the lens and microphone can be exposed by moving the base component 1 left and right when using the webcam 9 of the personal computer.

Parts 7 and 8 of the present invention that are in contact with the main body of the personal computer use a soft material such as sponge so as not to damage the main body 11 of the personal computer when moving the webcam 9 of the personal computer to the left or right.

The base component 1, the push button 2, and the portion 7 where the present invention touches the main body of the personal computer use an opaque material and optically close the lens 9 of the webcam of the personal computer.

The portion 7 of the present invention that is grounded to the main body of the personal computer has a donut-shaped shape in order to prevent light leakage.

The pad 6 that closes the microphone 10 of the webcam uses a material that has both flexibility and high sound insulation, such as silicone rubber and elastic foamed plastic, so as not to damage the PC body 10 and prevent sound leakage. Acoustically closes the microphone 9.

The source code using the programming language for general-purpose MCU (Arduino language) corresponding to FIG. 8 illustrated as an example of the implementation of the screen lock function of the present invention is illustrated below. The operating system of a personal computer is an example of Microsoft's Windows, and when a push button is pressed, a signal corresponding to a screen lock shortcut key (Windows key + L) is generated.
