The Internet and Its Legal Ramifications in Taiwan

Part I of this Article briefly introduces the five main legal issues related to Internet use in Taiwan. Part II discusses network-related copyright issues, including the doctrine of fair use, personal and corporate use of the Internet, and one of the first court cases in Taiwan on this issue. Part III discusses issues arising from commercial activity on the Internet, including the validity of on-line contracts, the use of digital signatures for authentication, and the applicability of Taiwan\u27s Broadcasting and Television Law, Cable Television Law, and Fair Trade Law to regulating commercial advertising on the Internet. Part IV discusses the relationship of the Internet and conventional mass communications media such as television and radio. It addresses the question of free speech, libelous or obscene content, and other issues which are familiar in a mass communications context but remain to be addressed as relating to the Internet. Part V deals with the protection of personal data on the Internet, especially in relation to the recently enacted Computer Processed Personal-Data Protection Law, and also touches on the protection of e-mail addresses and domain names. Part VI considers larceny, fraud, and other criminal acts perpetrated via computer networks (old crimes in new guises that have been termed “white collar” crime)
