Intrusion upon seclusion occurs when a perpetrator intentionally intrudes, physically, electronically, or otherwise, upon the private space, solitude, or seclusion of a person, or the private affairs or concerns of a person, by use of the perpetrator's physical senses or by electronic device or devices to oversee or overhear the person's private affairs, or by some other form of investigation, examination, or observation intrude upon a person's private matters if the intrusion would be highly offensive to a reasonable person. Hacking into someone else's computer is a type of intrusion upon privacy, as is secretly viewing or recording private information by still or video camera. In determining whether intrusion has occurred, one of three main considerations may be involved: expectation of privacy; whether there was an intrusion, invitation, or exceedance of invitation; or deception, misrepresentation, or fraud to gain admission. Intrusion is "an information-gathering, not a publication, tort ... legal wrong occurs at the time of the intrusion. No publication is necessary".
