Description

Today’s online privacy policies are failing consumers because they are difficult to understand and take too long to read. At the CyLab Usable Privacy and Security Laboratory at Carnegie Mellon University, we’ve developed and evaluated new ways of making privacy policies more usable for consumers. One approach is to distill privacy policy information into a simple privacy rating, and display this rating as an annotation to search engine results. Our laboratory studies have demonstrated that by including privacy ratings in search results consumers are motivated to seek out websites with better privacy policies and pay a small premium for better privacy. We’ve also conducted studies comparing a number of existing and new privacy policy formats to determine which are most usable, and developed and evaluated a new privacy “nutrition label” format based on concepts from standardized food labels. We’ve developed tools to generate our privacy nutrition labels automatically for websites that have Platform for Privacy Preferences (P3P) computer-readable privacy policies, and integrated this into the privacyfinder.org, a search engine run by our lab. We’ve also collected a large cache of P3P policies, which we’ve been able to mine for data about P3P and privacy policy trends. In this talk, I will review our approach to building a better privacy policy, discuss our studies, and highlight the lessons learned.
