Identity fraud is the use by one person of another person's personal information, without authorization, to commit a crime or to deceive or defraud that other person or a third person. Most identity fraud is committed in the context of financial advantage, such as accessing a victim's credit card, bank or loan accounts. False or forged identity documents have been used in criminal activity or in dealings with government agencies, such as immigration. Often today, the identities of real persons are used in the preparation of these false documents.
