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:

At the 2018 ILA Berlin Air Show from April 25–29, the Fraunhofer Institute for Laser Technology ILT is showcasing extreme high-speed Laser Material Deposition (EHLA): A video documents how for metal components that are highly loaded, EHLA has already proved itself as an alternative to hard chrome plating, which is now allowed only under special conditions.

At the ILA Berlin, hall 4, booth 202, Fraunhofer FHR will present two radar sensors for navigation support of drones. The sensors are valuable components in the implementation of autonomous flying drones: they function as obstacle detectors to prevent collisions. Radar sensors also operate reliably in restricted visibility, e.g. in foggy or dusty conditions. Due to their ability to measure distances with high precision, the radar sensors can also be used as altimeters when other sources of information such as barometers or GPS are not available or cannot operate optimally.
Drones play an increasingly important role in the area of logistics and services. Well-known logistic companies place great hope in these compact, aerial...
