Wearable devices (WDs) are a specific part of the general concept of the “Internet of Things”. This concept refers to infrastructure in which many sensors are designed to record, process, and store data locally, or interact with each other both in the medium range, through the use of radio frequency technologies (e.g. RFID, bluetooth, etc.), or through an electronic communications network. The devices involved are not only traditional computers or smartphones, but also daily life objects ("things"), such as wearable devices, home automation geo-referencing, and assisted navigation objects. Indeed, the “Internet of Things” refers to a further development of the Internet resulting from physical objects networking. These objects may be equipped with a unique identifier (for example, a serial number), recognizable even by radio frequency. However, the identification of these objects could also be made without resorting to radio tags, simply by combining sensors and automatic recognition procedures (for example, the recognition of a barcode carried out with a mobile phone connected to the Internet).The current state of research on this issue concerns mainly the use of WDs in daily life, and the enforcement of privacy rules, due to the capacity of WDs for the massive collection of personal data, such as in the health care and labour contexts, both sensitive areas for discrimination
