Abstract The development of computers and the Internet has inevitably led to the appearance of new crime types. Digital Revolution has opened a wide field of opportunities for fraud and counterfeiting in the global network. The purpose of this research is to analyze the legal implications of the First and Fourth Amendments as they relate to computer-related investigations. The research provides statistical information about fraud and counterfeiting, examples of both these types of computer crime, and arguments for criminalizing or not criminalizing ethical or unethical behavior in the Internet. Fraud on the Internet Fraud is defined as a situation when an offender illegally induces a victim by lies and unfulfilled promises to act for his or her benefit.
