Privacy protection is a tough task. It’s a harder task when it comes to software. Given that there are possibilities the webcam getting turned ON without any software indication about it, there is need to have hardware make it a possibility. Some devices have a light in the side of the webcam showing its ON. This is a more reliable feature because the webcam wouldn’t be ON without the light being ON. The chances of that light especially a LED light burning out is slim, even then it can be verified. So now, the user would know when their webcam is ON through hardware. The big concern is, there are so many electronic devices in the market today that don’t have this feature, especially mobile devices and smart TV. So those users are in a risk of not knowing when their webcam is ON when a malicious software would disable any software that shows such ON indication.
Also having this light acts as a quick response indicator to show the user the state of their webcam. This would help in increasing user satisfaction.
