A Jigsaw Puzzle Solver-based Attack on Block-wise Image Encryption for Privacy-preserving DNNs
Tatsuya Chuman, Hitoshi Kiya
Privacy-preserving deep neural networks (DNNs) have been proposed for protecting data privacy in the cloud server. Although several encryption schemes for visually protection have…
An Encryption Method of ConvMixer Models without Performance Degradation
Ryota Iijima, Hitoshi Kiya
In this paper, we propose an encryption method for ConvMixer models with a secret key. Encryption methods for DNN models have been studied to achieve adversarial defense, model pro…
Security Evaluation of Compressible Image Encryption for Privacy-Preserving Image Classification against Ciphertext-only Attacks
Tatsuya Chuman, Hitoshi Kiya
The security of learnable image encryption schemes for image classification using deep neural networks against several attacks has been discussed. On the other hand, block scrambli…
Security Evaluation of Block-based Image Encryption for Vision Transformer against Jigsaw Puzzle Solver Attack
Tatsuya Chuman, Hitoshi Kiya
The aim of this paper is to evaluate the security of a block-based image encryption for the vision transformer against jigsaw puzzle solver attacks. The vision transformer, a model…
