What is Cyber Law?

cyber laws to

control and reduce Internet communication abuse

• Communications and Multimedia Act 1998

Digital Signature Act 1997• Digital Signature is an identity verification standard

that uses encryption techniques to protect against e-mail forgery. The encrypted code consists of the user’s name and a hash of all the parts of the message.

• By attaching the digital signature, one can ensure that nobody can eavesdrop, intercept or temper with transmitted data.

Computer Crimes Act 1997• Gives protection against the

misuse of computers and computer criminal activities such as unauthorized use of programmed, illegal transmission of data or messages over computers, hacking and cracking of computer systems and networks.

• Users can protect their rights to privacy and build trust in the computer system.

qualified medical practitioners can practice telemedicine and that their patient's rights and interests are protected.
