We propose a public-key signature and encryption application which strongly relies on identity-based public-key cryptography. By alternately using obvious identity information like names and essential image data of the involved parties as public keys we preserve all advantages gained by identity-based public-key schemes, mainly including the absence of a public-key infrastructure [1]. On the other hand, all parties obtain only obvious and necessary information about other involved parties.
