In sampling survey, questions requiring personal or controversial assertions often give rise to resistance. In this situation, randomized response procedure is always used to help researcher to get the more accurate data from interviewee when the survey's topic is sensitive. This paper considers a new randomized response procedure that does not require direct answer from respondents. The method can be extended easily to allow multiple trial, just like Kuk's . This enables us to improve the efficiency of our estimator without increasing in sampling cost. The comparison of efficiency of this new method over the procedure proposed by Anthony Y. C. Kuk  has been shown theoretically. Choice of parameters combinations has been elaborated on by practical simulations of relative efficiency. As theoretically evident, an empirical study has been employed to examine the efficiency and feasibility of the proposed method.
