ZK-JPEG: Zero-knowledge Image Editing and Compression
New tool proves JPEG images were taken with real cameras
In brief
New tool proves JPEG images were taken with real cameras ZK-JPEG compresses images while proving they came from physical cameras Originally reported by Iacr.
Real camera proof
ZK-JPEG proves images came from physical cameras during compression
“Tools for generating deep fake photographs are proliferating with greater ease of use”
Deep fake threat
Deep fake photos are becoming easier to create and spread in pop culture
Current solution fails
Existing image authentication tools break when images are compressed
“Prior works use zero-knowledge to prove a published image's edit history”
New tool works
ZK-JPEG compresses images while proving they came from real cameras
“Our system is fast, flexible, and can be instantiated from off-the-shelf ZK tools”
How it works
Uses PicoZK to convert image editing code into zero-knowledge proofs
The big picture
ZK-JPEG compresses images while proving they came from physical cameras
