AUSTIN, TX -- (26 April 2012) By using the Internet for purchasing, communicating and entertaining, we've inadvertently left a digital behavior trail for others to scoop up and exploit. While it is possible to minimize leaking data bits by reading each site's privacy policy and responding appropriately, this is often not done.
"If people were to actually stop and read all of the privacy policies for every website visited, they could spend around 200-250 hours a year. That's about a month of time at work each year reading privacy policies," explains Lorrie Faith Cranor, Associate Professor of Computer Science, Engineering and Public Policy at Carnegie Mellon University. Cranor and her colleagues have conducted research in this area and will present their findings at the ACM's Computer-Human Interaction (CHI 2012) Conference at the Austin Convention Center.

Why Johnny Can't Opt Out: A Usability Evaluation of Tools to Limit Online Behavioral Advertising is one of the works presented by Cranor and her colleagues at the conference. It details the results of a 45-participant laboratory study investigating the usability of nine tools to limit online behavioral advertising (OBA). The research team found serious usability flaws in all tools tested. Participants found many tools difficult to configure and default settings were often minimally protective. Ineffective communication, confusing interfaces and a lack of feedback led many participants to conclude that a tool was blocking OBA when they had not properly configured it to do so. Without being familiar with many advertising companies and tracking technologies, it was difficult for participants to use the tools effectively. Additional presentations include:
Curation, Provocation and Digital Identity: Risks and Motivations for Sharing Provocative Images is also presented by researchers from Carnegie Mellon University. Among the billions of photos that have been contributed to online photo-sharing sites, there are many that are provocative, controversial, and deeply personal. Previous research has examined motivations for sharing images online and has identified several key motivations for doing so: expression, curation of identity, maintaining social connections, and recording experiences. However, few studies have focused on the perceived risks of posting photos online and even fewer have examined the risks associated with provocative, controversial, or deeply personal images.
The Implications of Offering More Disclosure Choices for Social Location Sharing, presented by researchers from the University of California, Irvine and Carnegie Mellon University, looks at how different types of disclosure options can influence users' privacy preferences for location sharing and can help in building better privacy configuration user interfaces.
Tag, You Can See It! Using Tags for Access Control in Photo Sharing, presented by researchers from Carnegie Mellon University and the University of North Carolina, addresses access control in photo sharing. Users often have rich and complex photo-sharing preferences, but properly configuring access control can be difficult and time-consuming. This research explores whether the keywords and captions which tag photos can be used to more intuitively create and maintain access-control policies.

About the CHI Conference
Featuring over 900 works, the CHI conference is the premier worldwide forum for the exchange of information on all aspects of human-computer interaction. Typically the works presented address the concerns of design, engineering, management and user experience professionals. This year's conference also features works that focus on: Digital Arts, Games and Entertainment, Human-Computer Interaction for Kids, Health and Sustainability. For complete information about this year’s conference, consult the Advance Program.
Originally a small conference for psychologists interested in user interface design, the annual CHI conference has grown to include a very diverse participant group such as interaction designers, computer scientists, engineering psychologists, developers, performing artists; and to deal with larger problems such as the organizational integration of technology, and the use of technology in the home rather than office settings. This year’s conference marks 30 years of research, innovation and development in the field of Human-Computer Interaction and is expected to draw more than 2500 professionals from over 40 countries. The experience at CHI 2012 offers innovative opportunities for interacting with future technologies.

Conference Sponsors
Organizations contributing to the financial support of the conference include Champion Sponsors Autodesk; Bloomberg; eBay; Google, Inc.; Microsoft Corp.; the National Science Foundation (NSF) and SAP.

About ACM
ACM, the Association for Computing Machinery, is the world’s largest educational and scientific computing society, uniting computing educators, researchers and professionals to inspire dialogue, share resources and address the field’s challenges. ACM strengthens the computing profession’s collective voice through strong leadership, promotion of the highest standards, and recognition of technical excellence. ACM supports the professional growth of its members by providing opportunities for life-long learning, career development, and professional networking.

CHI 2012 is sponsored by ACM’s Special Interest Group on Computer-Human Interaction (ACM SIGCHI). The scope of SIGCHI consists of the study of the human-computer interaction processes and includes research, design, development, and evaluation efforts for interactive computer systems. The focus of SIGCHI is on how people communicate and interact with a broadly-defined range of computer systems. SIGCHI serves as a forum for the exchange of ideas among computer scientists, human factors scientists, psychologists, social scientists, designers, educators, and practitioners involved in the design, implementation, and evaluation of interactive computing systems. Over 5,000 professional members of the SIGCHI community work together toward common goals and objectives.
