Digital Doppelganger

An unauthorized digital replica of a specific real person, constructed from cloned or forged elements of their expressive identity — including voice, appearance, and behaviour — that is functionally indistinguishable from the real individual. Unlike a Synthetic Persona, a digital doppelganger is derived from an actual person and can be deployed without their consent or knowledge.
