Question

Which of the three solutions can prevent data theft using an external camera and why?

Answer 1

If I understood your question correctly, the external camera is the BYOD device, BYOD environment entails or pre-requisites an ICT environment thats managed by some sort of a pre-defined, controlled and monitored systems admin. It is essentially the ICT environment that allows or disallows protocols as well as different IOT signals. Hence, in BYOD - the external camera is the least of a data-theft concern! The scripted under-layered data transmission the smart hacker actually can inject surreptitiously between the enabled ICT environment and the BYOD device is the more real concern. The camera could be blocked if it is part of the device by the same way, they are blocked or opened only with the operator’s permission on the cloud or net environment. Hence, the data theft detection is easier for me to dismiss or in fact detect any signal that is undeclared! However, if you mean the camera is extra or external of the BYOD device and is undeclared, it is not part of the ICT data-link anyway. The maximum the camera can steal is going to be as much as your eyes can steal! A screen shot can steal as much! But, I am not sure the data thats readable via a screen shot or clicked by an external camera is worth a steal really! This could not be used for official purposes as plagiarism is punishable! So, as cyber fraud auditors, while we review the plausibility, we must review the possibility and reasonability too! So, to answer your question, a camera / a body camera / a hidden camera, a phone recorder or video recorder - theoretically or argumentatively could be plausible threat. But, I think cyber thieves are smart people and would rather do something that’s worth the cost and effort with worth-while rationality and reasonability.
