In today's world, managing privacy has become a critical part of everyday life for many societies. Although privacy is important, the juxtaposition of privacy and social interactions is often misunderstood. The theory of communication privacy management (CPM), developed by Sandra Petronio, provides a vehicle to understand the way people handle decisions about revealing or concealing private information as they enact social relationships with others. Since the early 1980s, the development of CPM theory has been grounded in empirical research, and as a consequence, its principles have been repeatedly tested for their robustness in explaining the way people regulate privacy.

Though CPM initially grew out of an interpersonal and family tradition, it has evolved to be a viable tool for examining the regulation of disclosing and protecting private information in a vast array of contexts. For example, CPM has been used to understand disclosure of personal medical information in genetic testing, an examination of privacy and Weblogging, HIV disclosure and privacy, Internet privacy, privacy issues in e-commerce, studying privacy and radio frequency identification, privacy in cancer care, workplace surveillance, secrets in primary care, medical mistakes, and privacy expectations athletes have when they disclose to their athletic advisors. This theory meets the test of heuristic value and continues to grow through the applications of the original principles.

Reasons for Developing CPM Theory

The advancement of privacy management theory initially grew out of a desire to provide a conceptual framework to address the gaps found in the disclosure literature at the time. During the 1960s and 1970s, scholars in a number of fields extended Sidney Jourard's work on self-disclosure. Although a considerable amount of research was amassed, it was difficult to interpret the disparate findings without a conceptual map. As a result, a set of organizing principles needed to be developed to give context to the existing empirical research and find new ways of understanding what disclosure was and was not. Through this exploration, it became evident that disclosure should be considered in relationship to privacy and defined as a dialectic, or tension between privacy and disclosure. Defining privacy and disclosure in conjunction with each other gave a coherent wholeness to the way in which people make choices about telling or safeguarding private information. In other words, private information is the content of what people typically disclose and disclosure is the process by which people make that information public.

Connecting privacy and disclosure in this way affords the opportunity to see how people manage to be social and autonomous at the same time. The theory of CPM grew out of this exploration and not only has contributed to an understanding of privacy, but also has recast the nature of disclosure to reflect a concept larger and more involved than self-disclosure.

Principles of CPM

Using a metaphoric boundary between what is personal and what is public to illustrate how people conceptualize the process of privacy management, communication privacy management offers five principles that guide this theory. Principle one states that people believe they own their private information and assume they have the right to control access. For example, if a woman finds out that she has a genetic predisposition for breast cancer, she is likely to believe that she is the only person who has the right to tell others.
