Real photo or AI photo?
Mark sees a breaking-news photo spreading everywhere online, and can't tell whether it's real or made by AI.
WATERMARK
A hidden mark in the image
Bit explains: many AI tools now add a watermark, a hidden mark you can't see with your eyes but a scanner can read.
C2PA
A birth certificate for photos
C2PA is a standard that attaches origin information to the file, like a birth certificate for the photo: what made it and when it was edited. On some sites, you can click the Content Credentials icon to see it.
AI LABELS
Labels on social media
Big social networks also label AI-made content, and Europe and many other countries, including Vietnam, are writing rules for marking AI content into law.
LIMITS
No label doesn't mean real
But the mark can be lost when the image is cropped, screenshotted or reposted. No label doesn't mean the photo is real.
CHECK IT
Three steps to check
For important news, do three things: run a reverse image search, see who posted it first, and compare with mainstream news outlets.
