Internet fraud is a type of fraud or deception which makes use of the Internet and could involve hiding of information or providing incorrect information for the purpose of tricking victims out of money, property, and inheritance. Internet fraud is not considered a single, distinctive crime but covers a range of illegal and illicit actions that are committed in cyberspace. It is, however, differentiated from theft since, in this case, the victim voluntarily and knowingly provides the information, money or property to the perpetrator. It is also distinguished by the way it involves temporally and spatially separated offenders.
