The contest was part of the Student Ambassador for Privacy Protection Programme, organised by the Office of the Privacy Commissioner for Personal Data, Hong Kong (PCPD).
For their project, the team surveyed 101 young social media users, covering four aspects of their lives: personal, school, government and use of social media. They also spoke to teachers and counsellors.
"A school counsellor said she had heard about cases of students having suicidal thoughts," Olivia Chan Yee-shan said. "Those students' personal information online was being used as a tool by bullies against them."
As part of Privacy Awareness Week, PCPD has also released a survey about Facebook privacy, after interviewing 1,016 local users of the site. Only about 45 per cent of those aged 15 to 20 were worried about their private information on Facebook.
Dr Henry Chang Chung-yee, PCPD'sinformation technology adviser, said many young people do not realise the dangers of making their personal information available online.
