In an ICSI technical report published May 2, Gerald Friedland and Robin Sommer reported that they were able to identify where images posted online were captured. This information is automatically embedded by higher-end digital cameras and smart phones, such as the iPhone. People who post these images are often unaware that they are also posting data about their location.
Friedland and Sommer cross-referenced the latitude and longitude embedded in images with publicly available information, such as Google Maps Street View, to quickly find where photos were taken. The researchers, for example, identified the home addresses of people who put photos on Craigslist, even when those posting the photos had opted to hide their real names and email addresses.
In one search of YouTube videos, the researchers were able to find users with homes near downtown Berkeley by searching the embedded geo-location data. They included the search term “kids” since many home videos are of users’ children. They then searched for videos posted by the same users that had been filmed over 1000 miles away. Within fifteen minutes, the researchers were able to find a resident of Albany, California who was vacationing in the Carribbean, along with a dozen other users who might be vulnerable to burglary.
The results will be presented at the USENIX Workshop on Hot Topics in Security in August. The research has been featured on the ABC News Web site and in New Scientist magazine.Citation:

AI implications: Engineer's model lays groundwork for machine-learning device

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
