The Obama administration has declassified part of its plan to improve the security of cyberspace in an attempt to cultivate greater collaboration between government and civilian groups. More cooperation between the private sector and the U.S. National Security Agency is the centerpiece of the Comprehensive National Cybersecurity Initiative (CNCI). The declassified abstract of the plan reveals that the U.S. Department of Homeland Security will operate a new security system, called Einstein 3, that analyzes email and other data traffic into and out of federal networks. CNCI also urges merged oversight of federal spending on research and development in cybersecurity, with a particular focus on “leap-ahead” technology. Although the initiative acknowledges that traditional security approaches “have not achieved the level of security needed,” it says the federal government is now outlining “grand challenges” for the research community to help solve the most difficult problems.

The number of doctorates awarded in science and engineering (S&E) fields has risen for the fourth consecutive year, according to the National Science Foundation. Last year the United States produced 29,854 doctorate degrees in S&E fields, an increase of nearly 7 percent from the previous year. Computer science doctorates led the way with a 28 percent increase to 1,452 degrees, following a double-digit increase in CS doctorates from the previous year. CS doctorates are up 79 percent since 2002 and now represent a considerable share of not only S&E doctorates but all doctorate degrees. Non-U.S. citizens have been key to the growth in CS doctorate degree production. In the mid-to-late 1990s permanent or temporary visa holders received about half of CS doctorates, but last year they accounted for 61 percent. CS doctorates to U.S. citizens rose 42 percent from 2002 to 2006, but jumped 115 percent for non-U.S. citizens over the same period.

Rensselaer Polytechnic Institute’s “Adaptive Use Musical Instruments for the Physically Challenged” program enables students with severe physical disabilities to make music by just moving their heads. The system uses a digital video camera to track a student’s head movements on a computer screen and then translates the movements into piano scales or drum beats. Zane Van Dusen, a RPI undergraduate student in computer science and electronic media arts and communication, developed the idea of using a digital video camera to track the user’s head. A cursor is digitally placed on a portion of the student’s head, usually the tip of the nose, to follow the user’s movements. As the cursor moves, sounds are created based on the user’s movements. Moving the head completely in one direction will create a scale climb on the piano or a quick series of drum beats or a drum roll. The project’s ultimate goal is to eventually enable students to compose their own pieces to help students learn the creative process and build communication skills. “The client or patient doesn’t have to be a musician to participate,” says the American Musical Therapy Association’s Al Bumanis. “The goal is not usually a performance, it’s increasing communication skills, understanding, relearning lost skills.”

A coalition of seven academic institutions will use a $12.2 million National Institutes of Health grant to develop VIVOweb, a Facebook-style professional networking system for biomedical researchers across the United States. Participating institutions say VIVOweb will make it easier for scientists to find one another, ultimately enabling them to improve their ongoing studies and create long-term collaborative projects that could result in new discoveries. University of Florida professor Michael Conlon, the principal investigator on the project, says scientists often have difficulty finding each other, and currently the best way to connect with others performing similar research is through lists of publications. Dean Krafft, who is leading the project at Cornell University, says VIVOweb will use the Semantic Web to make information more available to scientists. The public also will be able to access the site, but some information will be available only to scientists. The open source software developed by Cornell for VIVOweb collects the facts a person is looking for and assembles a unique Web page just for that search. Participants expect to have VIVOweb connected across the country within two years, and eventually plan to connect scientists from around the world.

The computer industry had an opportunity to learn about the technical details of Google’s infrastructure during LADIS 2009, ACM’s recent SIGOPS International Workshop on Large Scale Distributed Systems and Middleware. Jeff Dean, a Google engineer who was one of the keynote speakers, also talked about Spanner, a new storage and computation system for automating the management of services across multiple data centers. Spanner, which will have a scale of 1 million to 10 million servers in the future, would be capable of automatically allocating resources across “entire fleets of machines,” Dean says. The goal will be “automatic, dynamic, worldwide placement of data and computation to minimize latency or cost.” Spanner also would offer a cost management strategy for addressing regional differences in bandwidth and power costs. Google would have energy management opportunities because Spanner can seamlessly shift workloads between data centers. Automated capacity management also would enable Google to route around failures or data center downtime as well as plan more energy-efficient facilities.

The Perception-on-Purpose (POP) project is an effort by European researchers to develop technology enabling a robot to integrate visual and audio data to facilitate purposeful perception. “It is not that easy to decide what is foreground and what is background using sound alone, but by combining the two modalities–sound and vision–it becomes much easier,” says project coordinator Radu Horaud. “If you are able to locate 10 sound sources in 10 different directions, but if in one of these directions you see a face, then you can much more easily concentrate on that sound and throw out the other ones.” The researchers followed this strategy in their development of algorithms that allowed their robot, Popeye, to reliably identify speakers. “Most often, sound research is conducted in specialized labs, with arrays of microphones and a very controlled acoustic environment,” Horaud says. “But we integrated our two microphones and two cameras onto the head of our Popeye. The idea is to have an agent-centered cognitive system.” Horaud believes there is a link between multi-sensory perception and cognition, and that some modern artificial intelligence applications are constrained by their inability to learn from their environment.

A scan of the Internet by Columbia University researchers searching for vulnerable embedded devices has found that nearly 21,000 routers, Webcams, and VoIP products are vulnerable to remote attack. They say there could be as many as 6 million vulnerable devices on the Internet. The scan also found that the devices’ administrative interfaces are viewable from anywhere on the Internet, and their owners have not changed the devices’ passwords from the manufacturer’s default. The study scanned networks belonging to the largest Internet service providers (ISPs) in North America, Europe, and Asia, and vulnerable devices were found in significant numbers in all parts of the world. Since starting the project last December, the researchers have scanned 130 million IP addresses and found nearly 300,000 devices whose administrative interfaces were remotely accessible from anywhere on the Internet. Devices with default passwords are most vulnerable, but others are theoretically vulnerable to brute-force password-cracking attacks. The researchers have provided ISPs with their findings, but Columbia professor Salvatore Stolfo says product manufacturers are the real culprits. He says that they need to hide their administrative interfaces by default and give customers clear instructions on how to alter the configuration to protect themselves. Stolfo also says that vendors should be more vocal in encouraging customers to change default passwords.

The University of Southampton’s School of Electronics and Computer Science (ECS) is launching a study that will explore how well people with disabilities can access Web services such as blogs, wikis, and social networking sites. The study, led by Mike Wald and E.A. Draffan in ECS’ Learning Societies Lab, is based on an accessibility toolkit that will enable users to test the accessibility of Web 2.0 services. The accessibility tools were developed as a result of the LexDis project, which identified strategies learners can use to enhance their e-learning experience. Part of the toolkit, Web2Access, provides an online checking system for any interactive Web-based service such as Facebook. Another key feature of the accessibility kit is Study Bar, which can work with all browsers and reads text out loud, spell checks, provides a dictionary, and can enlarge or change text fonts and colors to make text more readable. “We developed it because nowadays users contribute as well as read information and so you cannot just click on a button to see if Web sites are accessible and easy to use,” Draffan says. Wald says it is the first time that there has been a systematic way to evaluate and provide the results of accessibility testing of Web services.

Cornell University computer scientists have developed a method for generating the crashing and rumbling noises of objects made from thin harmonic shells such as cymbals and garbage can lids. The method, developed by professor Doug James and graduate students Jeffrey Chadwick and Steven An, will be presented at ACM’s SIGGRAPH Asia conference, which takes Dec. 16-19 in Yokohama, Japan. When a thin-shelled object falls or is struck, the metal or plastic slightly deforms and then snaps back into place, creating a vibration. Previous methods of synthesizing these noises did not account for the coupling effect that occurred when energy transfers from one vibration to another and back again, which resulted in a clean, clear sound that is more appropriate for a bell or chime. The new method accounts for this interaction and maps how the sound waves radiate to determine how the event will sound to a listener in any particular location. The researchers say that although their method is significantly faster than existing systems, the computations for a simple demonstration still take about an hour on a laptop. However, the researchers are hopeful that the simulation process can be accelerated by making some approximations. Their research is part of a larger project to synthesize various sounds, including dripping and splashing fluids, small clattering objects, and shattering glass.

Researchers in Barcelona are developing virtual reality spaces that incorporate touch-sensitive tiles and immersive animations. Pompeu Fabra University professor Paul Verschure says his research team has built an experience-induction machine as part of the PRESENCCIA project to understand how humans can exist in physical and virtual environments simultaneously. One of the project’s major challenges was creating a credible virtual environment, which required the researchers to understand how people’s brains construct a vision of the world. “Imagine what we see is sort of rapidly jumping about–that would not be a believable experience for us,” Verschure says. “So that means one thing we have really tried to engineer here also from a psychological perspective is how do I feed this continuity of expectations that our brain is generating about the world.” The researchers say the ultimate goal is to advance human-computer interaction beyond the traditional keyboard, screen, and mouse. “What we’re trying to do is to understand why people behave in a more or less natural way in a virtual reality,” says PRESENCCIA project coordinator Mel Slater. Petar Horki, a student at Austria’s Graz University of Technology, is using PRESENCCIA concepts to create a virtual reality system that uses mind control, allowing the user to simply think about an action to perform that action in the virtual world. “Actually, I’m not doing anything, I’m just imagining I’m doing a brisk foot movement, and by this imagination I can move at least in this virtual room,” Horki says.
