Smart and intelligent environment systems will be increasingly important in everyday life. Designing and developing them requires to face some research problems. A properly management of different types of sensors is very challenging but necessary in this area. A new wave of smart devices and systems brings customizable benefits for different users. Example of this are smart-phones, smart-bands, smart-watches, smart homes or smart cars. A successful combination of them bring interesting everyday life benefits.

One of the most important problems that needs to be solved in a practical way is the so called “multi-users problem”. Addressing it is fundamental for moving forward into a successful adoption in everyday life of the smart technologies mentioned before. Associating users and services in a spaces in which there are many possible combination of them, is a core task.

This work proposes a novel system based on interactions between Android smart-phones and Bluetooth Low Energy (BLE) technology beacons to deal with the challenges of a multi-user smart environment. We process data collected in a smart environment populated by many users. In particular we associate data collected and beacons. This processing generates database log traces containing measurements related to single user activities, helping in better matching services with users.
