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 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.
The story behind Vaultify — a father building a steganography platform in memory of his son Huey, who lost his sight at four and dreamed of photos that carry hidden stories.
