Abstract
In H-C interaction, computer supported cooperation andorganisation, computer mediated commerce, intelligentdata bases, teams of robots. etc. there will bepurposively deceiving computers. In particular, withinthe Agent-based paradigm we will have ``deceivingagents''''. Several kinds of deception will be present ininteraction with the user, or among people viacomputer, or among artificial agents not only formalicious reasons (war, commerce, fraud, etc.) butalso for goodwill and in our interest. Social control,trust, and moral aspects in artificial societies willbe the focus of theoretical worm as well as ofimplementation. Is there any special affinity betweenAI and deception?
