DBRA-Net: privacy-preserving cipher image retrieval via dual-branch residual attention network

Efficient multi-label generation-based image retrieval with privacy-preserving in cloud computing

Image Information Security Protection in the Big Data Era Based on Reversible Data Hiding in Encrypted Images

Massive image sharing and cloud-based storage in big data environments have significantly increased the risks of privacy leakage, unauthorized tampering, and insecure transmission. To address these issues, a reversible data hiding in encrypted images (RDHEI) framework integrating reserved room before encryption (RRBE)...

DLFaceGuard: unified face privacy and deep model protection using chaotic encryption

A deep learning-based face detection network that can accurately identify all faces in an image and a secure encryption key is generated using a novel chaotic system that exhibits high randomness and ensures the key’s unpredictability to protect both private data and the model.

Saliency-Guided Enhancement and Hybrid 5D Chaotic-ECC Encryption for Secure Military Image Processing

A hybrid encryption technique involving 5D hyperchaotic key stream generation and elliptic curve cryptography is employed to provide high resilience against different cyber-attacks such as differential attacks, chosen-plaintext attacks, and side-channel attacks.

Information Hiding Algorithm Optimized Based on BRISK Feature Extraction

While reversible information hiding of encrypted images can ensure communication security, traditional methods struggle to balance robustness against geometric attacks with high embedding capacity. To address this, an improved algorithm is proposed, combining Binary Robust Invariant Scalable Keypoints (BRISK) feature...
