Security challenges for wearable computing - a case study

This paper discusses IT- and information security challenges for wearable computing encountered during the WearIT@work project. The following novel ideas are introduced in this paper: authorization by proximity using dynamic context information to enable transfer of authorization from one party to another, a wearable pairing mechanism to use devices on other wearables, and a more intelligent management of dynamic IT-security policies to reduce computational overhead on wearable devices having limited capabilities. The last idea includes the importance of having a dynamic security baseline adapted to wearables to maintain the integrity and confidentiality of the body network as well as the privacy of the wearers' personal and biometric information.
