Smart glasses are wearable computers with a mobile Internet connection that are worn like glasses or that are mounted on regular glasses. They allow to display information in the user’s view field and to capture information from the physical world using e.g. camera, microphone and GPS receiver for augmented-reality (AR) application.
Most of the privacy considerations on IoT devices are also applicable for smart glasses:
1. lack of data control by users and especially by non-users;
2. inferences derived from data and repursing;
3. limitations on the possibility to remain anonymous for the user;
4. lack of anonymity due to the high identifiability of the information being processed;
5. the processing of special categories of data, which requires special safeguards;
6. the security risks attached to mass market products.
