Unified Camera Tamper Detection Based on Edge and Object Information
Sensors, 2015 In this paper, a novel camera tamper detection algorithm is proposed to detect three types of tamper attacks: covered, moved and defocused. The edge disappearance rate is defined in order to measure the amount of edge pixels that disappear in the current

Tamper-Proof Circuits: How to Trade Leakage for Tamper-Resilience [PDF]
, 2011 Tampering attacks are cryptanalytic attacks on the implementation of cryptographic algorithms (e.g., smart cards), where an adversary introduces faults with the hope that the tampered device will reveal secret information. Inspired by the work of Ishai et al. [Eurocrypt' 06], we propose a compiler that transforms any circuit into a new circuit with the
