Camera sensor identification can have numerous forensics and authentication applications.
In this work, we follow an identification methodology for smartphone camera sensors using …

Smartphones are a vital technology, they improve our social interactions, provide us a great
deal of information, and bring forth the means to control various emerging technologies, like …

Surveillance footage has become an integral part of law enforcement as video cameras
become ubiquitous, affordable and more reliable. Dynamic vision sensor (DVS) emerges as …

Sensor nodes massively deployed in Internet of Things are subject to physical capture,
hardware tampering, device cloning, and unauthorized device alteration. This paper …

In this paper, we present a novel physical unclonable function (PUF) based on time-domain
current difference measurement. By employing the aforesaid simplified current-mode PUF …

We report a novel method for increasing the number of challenge-response pairs (CRPs) of
a physically unclonable function (PUF) implemented using a 64× 64 perimeter-gated single …

In this paper, we present a novel on-chip physical unclonable function (PUF) based on the
cascode current mirrors. It exploits the process variation of a single transistor as the load of …

A mobile device method for certifying a mobile device includes: generating first fixed pattern
noise (FPN) information based on column FPN of an image sensor included in the mobile …

Abstract Physically Unclonable Functions (PUFs) have emerged as a viable and cost-
effective method for device authentication and key generation. Recently, CMOS image …

Due to the significant privacy risks that smartphones present and due to their importance in
device authentication and forensics investigations, fingerprinting smartphones have become …
