Computer-implemented method for ensuring the privacy of a user, computer program product, device
Jörg Schäfer,David Toma +1 more
- 06 Aug 2010
TL;DR: In this paper, a computer-implemented method and product ensures the privacy of a user and the utility of data communicated by a device, such as a vehicle telematics device, to a server, comprising receiving data at the device during the time period; processing, by the device, the received data; summarizing the processed data in a matrix, wherein the rows and columns of the matrix define circumstances of movement of the device.

Abelian Chern-Simons theory and linking numbers via oscillatory integrals
Sergio Albeverio,Jörg Schäfer +1 more
TL;DR: In this paper, a rigorous mathematical model of Abelian Chern-Simons theory based on the theory of infinite-dimensional oscillatory integrals developed by Albeverio and Ho/egh-Krohn is introduced.

Device Free Human Activity Recognition using WiFi Channel State Information
Neena Damodaran,Jörg Schäfer +1 more
- 01 Aug 2019
TL;DR: It is shown that it is possible to characterize activities and / or human body presence with high accuracy and two algorithms are proposed - one using a support vector machine (SVM) for classification and another using a long short-term memory (LSTM) recurrent neural network.
