While security in general is increasingly well addressed, both mobile security and multimedia
security are still areas of research undergoing major changes. Mobile security is characterized
by small devices that, for instance, make it difficult to enter long passwords and that cannot
perform complex cryptographic operations due to power constraints. Multimedia security has
focused on digital rights management and watermarks; as we all know, there are yet no good
solutions to prevent illegal copying of audio and video files.
