Cyberlaw in Hong Kong is essential reading not only for lawyers, but anyone connected with the web. The third edition of this popular title includes the latest amendments to the Personal Data (Privacy) Ordinance (Cap 486), with the chapter completely rewritten and includes a chart setting out the complex criminal regime that has been implemented. The Ordinance regulates the sale of personal data in direct marketing, creates a new offence for disclosing personal data without consent and imposes heavier penalties. A discussion on the landmark decision of Shi Tao v Privacy Commissioner for Personal Data is also extensively discussed, among other cases. This book also includes the modifications to the Copyright Ordinance (Cap 528) and the largely amended Trade Descriptions Ordinance (Cap 362) that affects advertising law on the internet. Defamation is another area of law that has seen an influx of cases in relation to the internet, especially in the UK, where the courts are recognising that messages on the internet are much more likely to 'go viral' than those sent through traditional media. There are also developments in the UK relating to the contentious area of 'metatags' and their relationship with trade mark law that are dealt with in this book, as those decisions will have great influence in Hong Kong. Cyberlaw also looks at China and the internet with the first-to-file principle of the trade mark law now overhauled. It also takes into account cybersquatting and how the courts are prepared to deal with the matter, even from foreign companies.
