Canberra: In a survey released Monday, 70 percent of Australian children aged between 8-17, said that their parents did not know about their internet usage.
The survey was conducted by global cyber security firm McAfee, Xinhua reported.
Nearly 50 percent said that they changed their browser histories in an effort to fool their parents, and 10 percent said they created fake social media profiles so their parents were unaware of their online activities.
The top online concern for users aged 8 to 12, was cyberbullying, while teenagers, aged 13 to 17, were more worried about losing privacy and being hacked.
Cyberbullying is the use of information technology to harass people in a deliberate, repeated, and aggressive manner.
Eighty percent of those surveyed had cyberbullying experiences, almost 40 percent said that they were victims.
