Abstract: A system and a method for attack detection includes a constellation of beacons, wherein each beacon is adapted to broadcast a unique beacon identification code (beacon ID); a terminal device adapted to receive a user trace of beacon IDs, and send a query to a backend server or routing device to determine an occurrence of an intrusion via a network; wherein the backend server is adapted to determine an occurrence of an intrusion by carrying out the steps of: computing spatial relational metrics between beacon devices; transforming beacon IDs as states of a Markov chain model, and estimating state transition probabilities based on the spatial relational metrics; recording user traces of beacon ID transitions when terminal device make queries; and running hypothesis test on the user traces against the Markov chain model to determine a status of intrusion.
