Next time you take a computer to a shop for repair, you may find a certificate displayed on the window promising that your sensitive data will be handled properly. The voluntary campaign is the latest move by the computer sector to allay privacy fears after the celebrity photo scandal, in which a private file on actor-singer Edison Chen Koon-hei's computer was stolen and distributed on the internet. A code of practice set out by the Chamber of Hong Kong Computer Industry advised repair workers to obtain consumers' consent before backing up the data, which they should erase completely after the computer was fixed. Shop operators should also record the repair works of technicians to ensure they abide by the guidelines. Certificates would be issued to shops that agreed to follow the guidelines within the next two weeks. Chamber president Jacky Cheung Yiu-shing expected it to cover about 80 per cent of its 400 member shops. Mr Cheung said there were more than 1,000 computer shops carrying out repair jobs in Hong Kong, and about a third were members of the chamber. He added that the names of registered shops would be listed on the chamber's websites and would also be given to the Consumer Council. 'We are trying to turn the risk into business opportunities. Consumers are recommended to bring their computers to shops which promise to protect their privacy,' he said. But Mr Cheung added that the public should also bear responsibility to protect the data themselves. 'Regular backup and erasing of sensitive data before taking the computer for repair are advised,' he said. In a written reply in the Legislative Council yesterday, Secretary for Commerce and Economic Development Frederick Ma Si-hang said the government would update non- legally binding guidelines for the public about the proper use of the internet in the light of recent public concern over the dissemination of information on the Web. The Internet Society Hong Kong also launched 'Project Net Respect' yesterday to educate the public on computer and internet ethics, chairman Charles Mok Nai-kwong said. The society will host seminars for more than 30 schools in the city. Meanwhile, education chief Michael Suen Ming-yeung said the government would provide HK$5 million to educate parents on information technology as a way to help them teach their children.
