Cyber law or Internet law is a term that encapsulates the legal issues related to use of the Internet. It is less a distinct field of law and covers many areas of law and regulation like internet access, internet usage, privacy, freedom of expression, and jurisdiction.
There are intellectual property related laws, in general, including copyright, rules on fair use, and special rules on copy protection for digital media, and circumvention of such schemes. The area of software patents is controversial, and still evolving.
The related topics of software licenses, end user license agreements, free software licenses and open-source licenses can involve discussion of product liability, professional liability of individual developers, warranties, contract law, trade secrets and intellectual property.
Many countries regulate the computing and communication industries. There are rules on the uses to which computers and computer networks may be put, in particular there are rules on unauthorized access, data privacy and spamming. There are also limits on the use of encryption and of equipment which may be used to defeat copy protection schemes. There are laws governing trade on the Internet, taxation, consumer protection, and advertising.
There are laws on censorship versus freedom of expression, rules on public access to government information, and individual access to information held on them by private bodies. There are laws on what data must be retained for law enforcement, and what may not be gathered or retained, for privacy reasons.
In certain circumstances and jurisdictions, computer communications may be used in evidence, and to establish contracts. New methods of tapping and surveillance made possible by computers have wildly differing rules on how they may be used by law enforcement bodies and as evidence in court.
