Investigating User Profiling and Privacy Leaks in Mobile Ad Networks

Mobile advertising networks seek to reach their audience by displaying targeted in-app ads to users. This requires user profiling, which is done by collecting information through ad and analytics libraries embedded in apps. The profile information may include demographic data, such as age and gender, as well as behavioral data, such as recent app use. A profile is linked to a device with a uniq...

The FBI Sentinel Project

In 2000, the United States Federal Bureau of Investigation (FBI) initiated its Trilogy program in order to upgrade FBI infrastructure technologies, address national security concerns, and provide agents and analysts greater investigative abilities through creation of an FBI-wide network and improved user applications. Lacking an appropriate enterprise architecture foundation, IT expertise, and ...

The Fbi Transform on Compact C∞ Manifolds

We present a geometric theory of the Fourier-Bros-Iagolnitzer transform on a compact C∞ manifold M . The FBI transform is a generalization of the classical notion of the wave-packet transform. We discuss the mapping properties of the FBI transform and its relationship to the calculus of pseudodifferential operators on M . We also describe the microlocal properties of its range in terms of the “...

Mapping urban pipeline leaks: methane leaks across Boston.

Natural gas is the largest source of anthropogenic emissions of methane (CH(4)) in the United States. To assess pipeline emissions across a major city, we mapped CH(4) leaks across all 785 road miles in the city of Boston using a cavity-ring-down mobile CH(4) analyzer. We identified 3356 CH(4) leaks with concentrations exceeding up to 15 times the global background level. Separately, we measure...
