Mayor Peduto Joins Uptake CEO To Talk Innovation, Collaboration
by Byron Spice | Wednesday, September 20, 2017
Pittsburgh Mayor Bill Peduto will sit down with Brad Keywell, Uptake CEO, for a fireside chat about cities as centers of innovation and other issues as Carnegie Mellon University celebrates the launch of the Machine Learning for Social Good fund.
The event will take place from 5:30 to 7 p.m. on Tuesday, Sept. 26, in the Rangos Ballroom of the Cohon University Center, and will be followed by a reception. Interim Provost Laurie Weingart, Machine Learning Department Head Manuela Veloso and Professor Roni Rosenfeld of the Machine Learning...
Decision To Share Personal Data Need Not Be All or Nothing
by Byron Spice | Wednesday, September 13, 2017
A smartphone app that uses the raw feed from a device's microphone or accesses its contact list can raise red flags for a user concerned about privacy. In many cases, however, the app doesn't need all the details that users find most sensitive.
Researchers at Carnegie Mellon and Peking universities have addressed this dilemma by creating a service, PrivacyStreams, that enables app developers to access the smartphone data they need for app functionality while assuring users that their...
Just 30 Libraries Account for More Than Half of Sensitive Data Taps
by Byron Spice | Monday, September 11, 2017
Smartphone apps that share users' locations, contacts and other sensitive information with third parties often do so through a relative handful of services called third-party libraries, suggesting a new strategy for protecting privacy, Carnegie Mellon University researchers say.
Controlling access to these third-party libraries, which help app developers make money by targeting people with ads or compiling marketing profiles, promises to be an effective way to limit the unwanted release of personal information. The research team developed an app...

Chances are, you’re reading this article on a web browser that uses HTTPS, the protocol over which data is sent between a web browser and the website users are connected to. In fact, nearly half of all web traffic passes through HTTPS. Despite the “S” for security in “HTTPS,” this protocol is far from perfectly secure.
“The HTTPS ecosystem has seen a long and somewhat depressing series of bugs,” says Bryan Parno, an associate professor of Computer Science and ...

School of Computer Science students captained teams that finished first and second in the Cambridge2Cambridge (C2C) three-day cybersecurity competition that ended July 27 at the University of Cambridge.
Robert Xiao, a Ph.D. student in the Human-Computer Interaction Institute, led the Unstoppables team, which won the £9,000 top prize, and won the £3,000 Leidos C2C Individual award as well. Carolina Zarate, a senior computer science major, captained the CrypticCrushers team, which took the second-place £4500 prize.
C2C is organized jointly by the University of Cambridge and the...

Carnegie Mellon University’s hacking team, the Plaid Parliament of Pwning or PPP, won its fourth World Series of Hacking title this weekend at the DefCon security conference in Las Vegas.
With four titles under their belt, the team has more wins than any other team in the 21-year history of the international competition. The 10 current members of PPP include eight undergraduates from the School of Computer Science and one Ph.D. student in SCS’s Human-Computer Interaction Institute.
''The problem-solving skills required to win these contests mimic those needed by governments...
Robots That Readily Expand or Shrink Would Be Possible
by Byron Spice | Thursday, July 27, 2017
Carnegie Mellon University researchers have found a way to design telescoping structures that can bend and twist, enabling robots of various shapes to collapse themselves for transport or entering tiny spaces, and making possible robotic arms and claws that can reach over or around large obstacles.
The researchers devised algorithms that can take a target shape that includes curves or twists and design a telescoping structure to match. They also created a design tool that enables even a novice to create complex, collapsible assemblies. The design possibilities range from something...
