23 A Review of “Camera Attribution Forensic Analyzer in the Encrypted Domain”

This paper is a review of a work previously published by the authors at IEEE WIFS’18 (Workshop on Information Forensics and Security), which received the Best Paper Award, and contains a summary of its main results. In WIFS’18 we proposed a new framework for the secure outsourcing of the image source attribution problem, in which the Photoresponse Non-Uniformity (PRNU) is used as a fingerprint to decide whether a test image was taken with a specific camera device. This method is fully unattended, that is, the secret key owner does not take part during the process. To this aim, we introduced improvements on the state-of-the-art in secure and unattended solutions for denoising. We also showed how to homomorphically perform filtering, polynomial, denoising and pixel-wise operations in a single round without the need of an interactive protocol

54 Homomorphic SVM Inference for Fraud Detection

Nowadays, cloud computing has become a very promising solution for almost all companies, as it offers the possibility of saving costs by outsourcing computation on-demand. However, some companies deal with private information, which must be protected before outsourcing. Banks, whose financial information is highly sensitive, are one remarkable example of this problem. Their typical processes must be run on their systems for security and regulation reasons, which impedes to take advantage of the scalability and flexibility benefits introduced by the cloud. A relevant example on which we focus in this work is the case of fraud detection systems, for which we propose the use of modern lattice-based homomorphic encryption for its secure execution. To this end, we implement and validate the performance of a homomorphic SVM (Support Vector Machine) classifier for secure fraud detection, showing the feasibility of securely outsourcing fraud detection inference
