How to tell if a photo has been edited
How to tell if a photo has been edited: forensic analysis reads compression signatures, manufacturer metadata baselines, and thumbnail mismatches across JPEG, WebP, PNG, and video.
Your camera’s fingerprint survives EXIF stripping — here’s how
Stripping EXIF metadata doesn’t make a photo anonymous. Two compression signatures — quantisation tables and Huffman tables — survive every standard strip and reveal both the original encoder and whether the file was re-processed. Here’s what forensic analysis actually reads.
How I built a JPEG encoder fingerprint database from scratch
How I built the DQT encoder fingerprint database inside snapWONDERS — deriving libjpeg tables mathematically from the ISO standard, and running a live accumulation pipeline with a trust model to guard against faked metadata. And what this has to do with Vaultify.
Why GPS in photos is more dangerous than most people think
A single geotagged photo shows where you were once. A few dozen shows where you live, work, and go every day — and most people are still sharing photos with full GPS data attached.
What your phone photos reveal about you — and why it matters
Every photo you take on your smartphone embeds a detailed record of where you were, what device you used, and exactly when — and most people have no idea how easy it is to read.
A new direction — deep digital media forensics
After some time away, the work is moving in a new direction. Hueyify has been paused. The story behind that is personal, and it’s told in full at kennethbspringer.au/our-story. The …
