The invention discloses a searching deployment-control method for fake-licensed vehicles. The searching deployment-control method comprises the following steps of: 1) extracting data; 2) calculating the lower bound of a stroke time; 3) identifying the vehicles by a quick hash algorithm for license numbers; 4) calculating the suspicion degrees of the fake-licensed vehicles: when data with the same Hash code and the same license number, judging whether the vehicle is a fake-licensed suspected vehicle, and the steps are as follows: calculating a time suspicion degree, and calculating a summarized suspicion degree; 5) selecting the optimal deployment-control point: sequencing the fake-licensed suspicion degrees of the vehicles to obtain a suspected fake-licensed vehicle table, and when the suspicion degrees are greater than a set threshold value, then judging the vehicles to be the suspected fake-licensed vehicles; carrying out a track analysis on the suspected fake-licensed vehicles, establishing a vehicle running track table according to passage numbers and elapsed time, and taking the passage number with the highest times in the same time slot as the optimal deployment-control point. The invention discloses a searching deployment-control method for fake-licensed vehicles, which is fast in calculation speed, high in identification accuracy, good in reliability, and also with a deployment-control interception function.
