An RFID based Smartphone Proximity Absence Alert System

An RFID based Smartphone Proximity Absence Alert System

Abstract:

We present the design, implementation and evaluation of an RFID based cellphone anti-lost and anti-theft measure. The cellphone owner is given an audio-visual alert at the very instant of the lost event, and, cellphone deduces the fact that it is away from its owner and executes the safety measures. This is realized by equipping the cellphone with a low-power RFID Reader and tagging the owner with a passive RFID token to determine a private space around him, which spans within 2-10 feet.
