AI GLOSSARY

Synthetic Persona

Security & Adversarial AI

A fully fabricated digital person assembled from artificially generated traits — including voice, appearance, and behaviour — derived entirely from training data rather than any real individual. In Agentic AI systems, synthetic personas can operate autonomously, maintaining consistent identities across interactions without any human behind them.
