Abstract :
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.
