An X-method to get sensitive information

A new approach, which is so called, to get the sensitive information is presented. The X-method consummates and improves the randomized response technique (RRT). It makes up essentially the limitation of Warner and Simmons models. It confirms both the deference of the individuals and the accuracy of the information. The result can be used in various sensitive information survey, such as the total number of the cheating students in examination, under table income, tax dodging, and ladies age, etc. It has potential applications in designing electronic device systems for information processing.
