European researchers working on the Remote EnTrusting by RUn-time Software authentication (RE-TRUST) project have proposed a solution to trusted computing that they say offers better security and authentication. RE-TRUST uses logic components on an untrusted machine to allow for remote entrusting authentication. “RE-TRUST will have a major impact on all commercial applications and solutions where security or trust is a concern, independently of whether they are based on a client-server or a peer-to-peer paradigm,” says RE-TRUST coordinator Yoram Ofek. RE-TRUST solutions could work with peer-to-peer networks to enable them to become a new trusted distribution channel. The RE-TRUST team also developed trust solutions for code mobility, reconfigurable computing for software protection, and orthogonal replacement. “All applications and solutions running over a network, such as the Internet, can benefit from the RE-TRUST approach,” Ofek says.

The flagging attraction of science, technology, engineering, and math (STEM) professions to young women is partly attributed to the geek factor, or the perception of such careers as uncool, socially isolating, and primarily geared toward males. The National Center for Women & Information Technology estimates that about 17 percent of high school girls take advanced computer science placement exams, which represents the lowest percentage of females among all such tests. Meanwhile, the number of women earning computer science degrees fell from 37 percent in 1985 to 18 percent in 2008. AT&T Labs researcher Amanda Stent says that “a movement to reclaim the notion of ‘geek’ ” is underway to reverse this trend, and she is a member of a group dedicated to encourage more young women to become passionate about science and technology. Stent stresses that engineers, technologists, and scientists often work in groups and invent community-building, societally beneficial products.

Queensland University of Technology (QUT) Ph.D. researcher Suriadi is investigating using an anonymous credential system, an Internet authentication system from the 1980s, to enable Web users to securely log in only once per Internet session. Suriadi says future single sign-on systems could give users access to multiple accounts–including email, bank, and shopping–but would need to provide extreme privacy to avoid hackers. He says the anonymous credential system could enhance the security and privacy of a single sign-on system. “The system works by revealing as little information about who you are as necessary for logging into an account, therefore allowing you to remain anonymous,” Suriadi says. A single sign-on system backed by the anonymous credential system requires the cooperation of business and organizations to enable it, Suriadi notes.

Researchers remain optimistic about the prospect of keeping track of the exaflood of data, from gene sequences and distant pulsar signals to YouTube videos and email. During the recent annual meeting of the American Association for the Advancement of Science, one session gave scientists and other academics an opportunity to learn more about some current strategies for storing data and using it productively. University of California at San Diego professor Larry Smarr demonstrated how genetic sequences from ocean bacteria can be coupled with environmental information about the organisms. Smarr said researchers were able to target specific gene sequences, annotated with helpful information. Meanwhile, Google researcher Hal Varian said the company’s Google Insights for Search analytical tools used information on individual searches for Toyota automobiles to accurately predict its sales volume.

Abu Dhabi University (ADU) researchers have developed Driver Riskometer, a smartphone application that tracks a user’s mobile phone activity while driving. The application records the vehicle’s top and average speed, the number of calls made, the time spent on calls, and the time spent tapping the phone’s keys. The driver’s performance is scored at the end of a trip on a scale of one (very safe) to seven (very risky). Studies have found that drivers using mobile phones are four times as likely to cause a crash as those not using a phone. “The idea is to give people feedback about their risk on the motorway and get them to enhance their driving,” says ADU professor Ashraf Khalil. Drivers can check their records for a single journey or for a given day or month. After each trip, the overall risk score is recalculated based on the more recent performance.
