How sensitive is your personal information?

The sensitivity of personal information is one of the most important factors in determining the individual's perception of privacy. A "gradation" of sensitivity of personal information can be used in many applications, such as deciding the security level that controls access to data and developing a measure of trust when self-disclosing personal information. This paper introduces a theoretical analysis of personal information sensitivity and defines its scope and puts forward possible methods of gradation. A methodology is proposed that can be used for developing a classification scheme of personal information.
