eb cam or webcam (web camera) is a live and real-time camera whose images can be accessed using the World Wide Web, instant messaging, or a PC video calling or video conferencing application.
Webcam is increasingly used as web surveillance cams to monitor security, traffic beach, office, and other sensitive areas.
But it isn’t just governments who are co-opting webcams to do their surveillance work.
In 2010, high school administrators in Pennsylvania took more than 30,000 webcam images of students using remote access tools installed on school-issued laptops.
Professor Alan Woodward, a cyber security specialist, said: ‘The really scary thing is that people buy these cameras for their own security.Hacking can be prevented simply by changing the factory-set default security codes that every camera comes with.A large number of buyers will be parents who use the devices to monitor babies and young children.Wolf said she was a victim of "sextortion", in which perpetrators demand sexual favors to prevent them from releasing intimate photos or videos online that are often obtained through hacking into computers, webcams and smartphone cameras.Four months before Wolf won the title, she said a stranger hacked into her computer webcam without her knowing it and took nude photos of her in her bedroom.
