An Anti-Fuzzing Approach for Android Apps
Type: Conference Proceeding,Publication Research Area(s): Digital
Published: 2023 | By: Chris Chao-Chun Cheng
One of significant mobile app forensic analysis problems is the app evidence extraction from the device. Given the fact that mobile apps could generate more than 19K files in a device [6], simply manually inspecting every file is time consuming…
Forensic Analysis of Android Cryptocurrency Wallet Applications
Type: Conference Proceeding,Publication Research Area(s): Digital
Published: 2023 | By: Chen Shi
Crypto wallet apps that integrate with various block-chains allow the users to make digital currencies transaction with QR codes. According to reports from financesonline [3], there is over 68 million crypto wallet app users in 2021. As new crypto wallets…
Variations and Extensions of Information Leakage Metrics with Applications to Privacy Problems with Imperfect Statistical Information
Type: Conference Proceeding,Publication Research Area(s): Digital,Forensic Statistics
Published: 2023 | By: Shahnewaz Karim Sakib
The conventional information leakage metrics assume that an adversary has complete knowledge of the distribution of the mechanism used to disclose information correlated with the sensitive attributes of a system. The only uncertainty arises from the specific realizations that are…
Camera Device Identification and the Effects of Underexposure
Type: Dissertation,Publication Research Area(s): Digital,Forensic Statistics
Published: 2023 | By: Seth Pierre
Technology today allows a photograph from a digital camera to be matched with the camera that took it. However, the matching software was created over 10 years ago using data that is not necessarily representative of today’s data. The objective…
Shifting decision thresholds can undermine the probative value and legal utility of forensic pattern-matching evidence
Type: Publication Research Area(s): Forensic Statistics,Implementation and Practice
Published: 2023 | By: William Thompson
Forensic pattern analysis requires examiners to compare the patterns of items such as fingerprints or tool marks to assess whether they have a common source. This article uses signal detection theory to model examiners’ reported conclusions (e.g., identification, inconclusive, or…
A statistical approach to aid examiners in the forensic analysis of handwriting
Type: Publication Research Area(s): Forensic Statistics,Handwriting
Published: 2023 | By: Amy Crawford
We develop a statistical approach to model handwriting that accommodates all styles of writing (cursive, print, connected print). The goal is to compute a posterior probability of writership of a questioned document given a closed set of candidate writers. Such…
Ensemble learning for score likelihood ratios under the common source problem
Type: Publication Research Area(s): Forensic Statistics
Published: 2023 | By: Federico Veneri
Machine learning-based score likelihood ratios (SLRs) have emerged as alternatives to traditional likelihood ratios and Bayes factors to quantify the value of evidence when contrasting two opposing propositions. When developing a conventional statistical model is infeasible, machine learning can be…
