The Privacy Policy Permission Diagram - Toward a Unified View of Privacy (Doctoral thesis, University of Calgary, Calgary, Canada).

When individuals disclose information, they are making decisions about giving up a portion of their privacy. Organizations use privacy policies to communicate their practices to their clients. A privacy policy is a set of statements that specifies how an organization gathers, uses, discloses, and maintains a client’s data. Most privacy policies, however, lack a clear, complete explanation of how data providers' information is used. In his 1976 paper titled The Entity-Relationship Model -- Toward a Unified View of Data, Peter Chen proposes a diagrammatic technique to model entities and their relationships. This technique is independent of the entities' domains. Inspired by this contribution, we propose a modeling methodology called Privacy Policy Permission Diagram (PPPD), which provides a uniform, easy-to-understand representation of privacy policies, that can accurately and clearly determine how data is used within an organization's practice. Using this modeling methodology, privacy policies are presented in a diagram, and are populated into a privacy catalog. The privacy catalog can then be used to store privacy policies and their relationships. This methodology highlights inconsistencies and inaccuracies in the privacy policy.engUniversity of Calgary graduate students retain copyright ownership and moral rights for their thesis.
