Fighting Fake Videos and Pictures: How We Can Tell What's Real Online

The Big Problem: Too Many Fakes! Have you ever seen a video of a famous person saying something strange and wondered, "Did they really say that?" These days, computers can make fake videos and pictures that look super real. These are called "deepfakes," and they're causing big problems online. Imagine if someone made a fake video of your principal announcing that school was canceled tomorrow - but it wasn't true! That's why we need a way to know what's real and what's fake on the internet. Our Solution: A Digital Truth Stamp We built something called a "ContentGuard" system. Think of it like a special stamp that creators can put on their pictures and videos to prove they're real. This stamp can't be copied or faked because it uses two cool technologies: Blockchain: Like a digital notebook that everyone can see, and nobody can erase or change what's written in it IPFS: A way to store files that doesn't depend on just one computer (so files don't disappear if one computer breaks) How It Works When someone creates a picture or video, our system: Puts the original file in a special storage system (IPFS) Creates a unique "fingerprint" of the file Writes this fingerprint in the blockchain notebook Gives the creator a certificate saying "This is real!" Later, when you see that picture or video online, you can check if it has this special stamp. If it does, you know it's the real thing! What Our System Looks Like We built three main parts that work together: The Website (What You See) This is where people can: Connect their digital wallet (like an online ID) Upload their pictures and videos to get them stamped as real Check if something they found online is real or fake The Behind-the-Scenes Part This is like the brain of our system. It: Handles files when they're uploaded Talks to the blockchain and storage system Keeps track of which files are real The Permanent Record (Blockchain) This is where we keep the list of all real content. It's: Impossible to change or delete Open for anyone to check Always available, even if our website goes down How People Can Use It For Regular Internet Users If you want to make sure your pictures and videos are trusted: Visit our website and connect your digital wallet (
