Unified Camera Tamper Detection Based on Edge and Object Information [PDF]
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

Digital Evidence for Database Tamper Detection
Journal of Information Security, 2012 Most secure database is the one you know the most. Tamper detection compares the past and present status of the system and produces digital evidence for forensic analysis. Our focus is on different methods or identification of different locations in an oracle database for collecting the digital evidence for database tamper detection.
