A profiling adversary is an adversary which aims to classify messages into pre-defined profiles and thus gain useful information regarding the sender or receiver of such messages. Usual chosen-plaintext secure encryption schemes are capable of securing information from pro-filers, but these schemes provide more security than required for this purpose. In this paper, the authors study the requirements for an encryption algorithm to be secure only against profilers and finally give a precise notion of security for such schemes.
