New CMU Study Highlights Challenges of Complex Trade-Off in Privacy Decision-Making; “Privacy is not a modern invention, but a historically universal need,” says CyLab's Acquisti

In "Privacy and Human Behavior in the Information Age", a review published in the Jan. 30 special issue of the journal Science, CMU CyLab's Alessandro Acquisti and a team of fellow CMU researchers have detailed the privacy hurdles people face while navigating in the information age, and offered some perspectives on what should be done about privacy at a policy level.

In their review, Acquisti, professor of information technology and public policy at CMU’s H. John Heinz III College, and his co-authors, Laura Brandimarte and George Loewenstein, challenges a number of claims that have become common in the ongoing debate over privacy, including the claim that privacy may be an historical anomaly, or that people do not really care for data protection.

“Privacy is not a modern invention, but a historically universal need,” said Acquisti, the lead author. “In certain situations, individuals will care for privacy quite a lot and act to protect it, but advances in technology and the acceleration of data collection challenge our ability to make self-interested decisions in the face of increasingly complex tradeoffs.”

In the paper, the authors identify three themes prevalent in empirical research on privacy decisions and behavior: People are often uncertain about the consequences of privacy-related behaviors and their own preferences over these consequence; People’s concern, or lack thereof, about privacy is context dependent; and Privacy concerns are malleable, particularly by commercial and government influences.

CMU CyLab PPP and CUPS teams win “Capture the Flag” and “Crack Me If You Can" contests at DEFCON 22

Members of CMU CyLab's Plaid Parliament of Pwning (PPP)
Carnegie Mellon University demonstrated its cyber prowess at DEFCON 22 by winning the “Capture the Flag” and “Crack Me If You Can” contests ...

Carnegie Mellon’s computer hacking team, the Plaid Parliament of Pwning (PPP), took first place for the second consecutive year in the Capture the Flag (CTF) contest. Globally, hundreds of teams battle throughout the year for one of 20 slots at DEFCON’s CTF competition, which has been called the “World Series of hacking.”

“Our team competed against universities and also against large defense contractors. This win is a huge accomplishment for our team,” says team advisor David Brumley, an associate professor of Electrical and Computer Engineering and the technical director of Carnegie Mellon CyLab.

The PPP team qualified for DEFCON for the last three years, and won first place in 2013 and again in 2014. The PPP team is part of CyLab’s Undergraduate Computer Security Research group, and it consists of 35 members from the College of Engineering and the School of Computer Science.

At DEFCON 22, the team was limited to eight members: George Hotz, Ryan Goulden, Tyler Nighswander, Brian Pak, Alex Reece, Max Serrano, Andrew Wesie, Ricky Zhou ...

A second team, this one from CyLab Usable Privacy and Security (CUPS) Lab, and simply named “cmu,” won the Street Division category in the “Crack Me If You Can” contest. In this two-day event sponsored by KoreLogic Security, teams exposed or “cracked” encrypted passwords.

"The students leveraged what they had learned from our research studies to develop their winning strategy," CUPS Director Lorrie Cranor says, "It is remarkable for a first-time team to win this competition." Cranor and fellow CyLab faculty members Lujo Bauer, Nicolas Christin, along with their team of students, are responsible for a growing body of work on passwords.

A Decade Into Its Vital Work, Another Savory SOUPS, A Report from the 10th Annual Symposium On Usable Privacy and Security



CMU CyLab's Dr. Lorrie Cranor, Founder of CUPS and SOUPS preps
for welcoming remarks at SOUPS 2014


The CyLab Usable Privacy and Security Laboratory (CUPS) 10th Annual Symposium on Usable Privacy and Security (SOUPS) was hosted by Facebook at its headquarters in Menlo Park, California (7/9/14 - 7/11/14). CUPS Director Lorrie Cranor welcomed the attendees, with the record-breaking numbers in both attendance and papers submitted. For three full days of proceedings, hundreds of researchers from business, academia and government communed together amidst the proliferation of signage which has come to characterize the social media giant's corporate culture: e.g., "Ship Love," "Ruthless Prioritization," "Demand Success," Nelson Mandela, arms outstretched, with the caption, "Open the Doors," etc. (Not so subliminal messaging.)
 
Perhaps more poignantly than any previous SOUPS keynote, Christopher Soghoian of American Civil Liberties Union (ACLU) articulated the vital nature of research into usable privacy and security. Putting flesh and blood on these issues, Soghoian used examples from the shadow world of investigative reporters and whistle-blowers to highlight the need for privacy and security software that is not only robust but eminently usable. One great benefit of the revelations brought forth by Glenn Greenwald in the Edward Snowden affair, Soghoian opined, is that there has been increased crypto adoption by journalists.
But the heightened engagement has also brought long-standing problems into a harsh new light. For example, Soghoian told SOUPS attendees, many investigative journalists using PGP still do not realize subject lines are not encrypted. "The best our community has to offer sucks, the usability and the default values suck," Soghoian declared, "the software is not protecting journalists and human rights activists, and that's our fault as researchers"

As contributing markets factors for why we still don't have usable encryption, Soghoian cited: potential data loss ("telling your customer that they've just lost every photo of their children is a non starter"), current business models, and of course, government pressure.

In other parts of his very substantive keynote, Soghoian touched on consumer issues related to the efficacy of privacy and security. He elucidated the differences in privacy and security between the iPhone and the Android: "The privacy and security differences ... are not advertised." He also shed light on a new aspect of the growing gap between rich and poor, "security by default for the rich," and "insecurity by default for the poor." "Those who are more affluent get the privacy benefits without shopping around," he explained, because the discounted, and mass-marketed versions of software often do not have the same full-featured privacy and security as the more expensive business or professional versions.

[NOTE: Full-length video of Soghoian's keynote is available via the CyLab YouTube Channel.]

Several awards were also announced during the opening sessions, including:

The 2014 IAPP SOUPS Privacy Award for the paper with the most practical application in the field of privacy went to Would a Privacy Fundamentalist Sell Their DNA for $1000...If Nothing Bad Happened as a Result?
