NC State Research Advances Voice Security Technology

09.03.2010
Most people are familiar with security technology that scans a person’s handprint or eye for identification purposes. Now, thanks in part to research from North Carolina State University, we are closer to practical technology that can test someone’s voice to confirm their identity.

“The big picture is speaker authentication by computer,” says Dr. Robert Rodman, professor of computer science at NC State and co-author of a new paper on the subject. “The acoustic parameters of the voice are affected by the shape of the vocal tract, and different people have different vocal tracts,” Rodman explains. “This new research will help improve the speed of speech authentication, without sacrificing accuracy.”

Rodman explains that speech authentication could have a host of applications in this age of heightened security and mobile electronics. “Potential users of this technology include government, financial, health-care and telecommunications industries,” Rodman says, “for applications ranging from preventing ID theft and fraud to data protection.”

Current computer models that are used to compare acoustic profiles, effectively evaluating whether a speaker is who he says he is, may take several seconds or more to process the information, which is still too long for the technology to gain widespread acceptance. “In order for this technology to gain traction among users,” Rodman says, “the response time needs to improve without increasing the error rate.”

To address this problem, Rodman and his fellow researchers modified existing computer models to streamline the authentication process so that it operates more efficiently. “This is part of the evolution of speech authentication software,” Rodman says, “and it moves us closer to making this technology a practical, secure tool.”

The research was co-authored by NC State’s Rodman; Rahim Saeidi, Tomi Kinnunen and Pasi Franti of the University of Joensuu in Finland; and Hamid Reza Sadegh Mohammadi of the Iranian Academic Center for Education, Culture & Research.

The research, “Joint Frame and Gaussian Selection for Text Independent Speaker Verification,” will be presented at the International Conference on Acoustics, Speech and Signal Processing (ICASSP) in Dallas, March 14-19. The research was funded, in part, by the Centre for International Mobility.

NC State’s Department of Computer Science is part of the university’s College of Engineering.

Im Focus: Powerful IT security for the car of the future – research alliance develops new approaches

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.

Vehicles already offer diverse communication interfaces and more and more automated functions, such as distance and lane-keeping assist systems. At the same...

Im Focus: Molecular switch will facilitate the development of pioneering electro-optical devices

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.

The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...

Im Focus: LZH showcases laser material processing of tomorrow at the LASYS 2018

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...

Im Focus: Self-illuminating pixels for a new display generation

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?

At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
