摘要

One of the major issues in digital forensics is that cyber criminals tend to hide digital evidence before forensic tools are applied to find them. A simple but effective method to evade detection is to embed textual information in a picture such as a screenshot. On the detective's side, we can use Optical Character Recognition (OCR) algorithms to retrieve the textual information from a picture or from a PDF document. However, the main challenges of the current solutions on standalone computers include scalability and performance. In this paper, we present a cloud-based framework which consists of a set of virtual machines and a job management system. We also show the mathematical derivation of our system configurations.
