FlowCrypt: Flow-Based Lightweight Encryption With Near-Lossless Recovery for Cloud Photo Privacy
- Published
- Record updated
Summary
FlowCrypt is a flow-based image encryption framework for cloud photo privacy that aims for near-lossless recovery without an auxiliary reference image. It uses a secret-key-guided random split and a Flow-based Encryption/Decryption module built on conditional affine coupling blocks. The authors report recovery quality of 115 dB across four datasets, uniformly distributed cipher images, and a model of only 1 M parameters.
