An evaluation method is developed to measure the cost/ effectiveness of two new inference control methods. The factors of the evaluation function consist of: 1) preparation cost for the control method, 2) query complexity, and 3) security level under various attacks. Each control method combines the merit of some popular concepts; the first method is based on restriction, and the second on perturbation. Simulation results indicate that both methods have higher preparation cost, better security, and faster response time than Cox's method and Beck's method. Finally these two new methods are compared to each other.
