Image Steganography: A Beginner's Guide

I’ve been busy lately writing a comprehensive 4-part series on steganography and error correcting codes on the Black Hills Information Security blog.

The step-by-step guide takes you from the fundamentals of steganography all the way through a full image steganography example. Not only that, but it also includes a steganography tool in Python for you to use - and explains it!

Want an easier way to get through all 4 parts and learn steganography techniques more quickly? Download a PDF of all the articles to get a comprehensive, 30-page steganography guide that will show you every step of the way.

However, hiding data in images wasn’t enough. The guide also introduces error correcting codes, which can help reduce errors caused when the picture your message is hidden in goes through compression. You not only get a hamming code tutorial, you also see actual hamming code examples to help you learn.

Understanding how to hide data in an image using steganography, and prevent that data from being corrupted, can prove very helpful for both attack and defense, including forensics. Check out the series of articles to learn image steganography algorithms and techniques, or download free, open-source steganography software in Python from Github.
