As other users has already answered, sensors can detect a specific unit (person, animal or whatever else) if the unit has a unique ID. At the actual date the most reliable and widely diffused system is just the RFID but the detection range is short and this kind of solutions are used to detect someone just when passing in specific points (i.e. parkind, entry / exit gate etc.).
The most (probably illegal) reliable way to track a person instead is following - using different kind of sensors / RF detection systems - through its mobile device or a GPS unit.
