Interaction data are identifiable even across long periods of time
Fine-grained records of people’s interactions, both offline and online, are collected at large scale. These data contain sensitive information about whom we meet, talk to, and when. We demonstrate here how people’s interaction behavior is stable over long periods of time and can be used to identify individuals in anonymous datasets. Our attack learns the profile of an individual using geometric deep learning and triplet loss optimization. In a mobile phone metadata dataset of more than 40k people, it correctly identifies 52% of individuals based on their 2-hop interaction graph. We further show that the profiles learned by our method are stable over time and that 24% of people are still identifiable after 20 weeks. Our results suggest that people with well-balanced interaction graphs are more identifiable. Applying our attack to Bluetooth close-proximity networks, we show that even 1-hop interaction graphs are enough to identify people more than 26% of the time. Our results provide strong evidence that disconnected and even re-pseudonymized interaction data can be linked together making them personal data under the European Union’s General Data Protection Regulation
Descartes, René
Scholars generally consider René Descartes to
be the father of early modern philosophy insofar
he rejected scholasticism, Aristotelianism,
but also Renaissance philosophies and
grounded a new system of knowledge whose
roots lie solely in the mind and not in previous
assumptions. This defines a modern self that
achieves the knowledge of nature and shapes
the modern universe. In the Discours de la
MĂ©thode (1637) and the Meditationes de
prima philosophia (1641), after rejecting earlier
education, doctrines, and scientiæ, Descartes
isolates the powers of the mind (i.e.,
clear and distinct ideas) as the beginning of
any certainty. Yet, having considered Descartes’
system as dismissing all doctrines and
beliefs, in this entry I will first examine some
relations between the French philosopher and
those contexts and then discuss the novelties of
his system. After a short biography, in the
second section, I will briefly explore the interrelations
between Descartes and Renaissance
scholars, whom he reproached for their precipitate
conclusions. Third, I will unearth his criticism
of Aristotelian-scholastic philosophy
(which he reproached for its preconceptions),
while highlighting his attention to a few Aristotelian
texts. Fourth, I will investigate a few
innovative aspects of his methodology; this
consists of novel combination of intellectual
cognition and experimentation. As a result,
Descartes’ entire natural philosophy consists
of a theoretical framework that defines the
principles of knowledge and the architecture
of science, while the body of all disciplines and
the knowledge of particular issues are methodologically
and experientially constructed.
Despite several limitations, Descartes’ system
is remarkably innovative
