Dataset for file fragment classification of image file formats

Image file formats

This tutorial is about image file formats: what are they, what are they used for, what are their differences and how we choose between them. The tutorial assumes a basic understanding of general digital imaging; of which a quick summary of important features is provided below. Pixel: a digital image is represented as a rectangular grid of dots, where each dot has a specific spatial position and...

Using NLP techniques for file fragment classification

The classification of file fragments is an important problem in digital forensics. The literature does not include comprehensive work on applying machine learning techniques to this problem. In this work, we explore the use of techniques from natural language processing to classify file fragments. We take a supervised learning approach, based on the use of support vector machines combined with ...

Image File Formats: Past, Present, and Future1

Despite the rapid growth of the Internet for storage and display of World Wide Web–based teaching files, the available image file formats have remained relatively limited. The recently developed portable networks graphics (PNG) format is versatile and offers several advantages over the older Internet standard image file formats that make it an attractive option for digital teaching files. With ...

A File Fragment Classification Method Based on Grayscale Image

File fragment classification is an important and difficult problem in digital forensics. Previous works in this area mainly relied on specific byte sequences in file headers and footers, or statistical analysis and machine learning algorithms on data from the middle of the file. This paper introduces a new approach to classify file fragment based on grayscale image. The proposed method treats a...
