TL;DR: Experimental results show that the proposed scheme for color medical image copyright protection based on a chaotic system and quaternion polar harmonic transforms (QPHTs) is robust to geometric attacks and common attacks and that it has better performance than similar lossless watermarking schemes.
Journal ArticleDOI
PPDP: An efficient and privacy-preserving disease prediction scheme in cloud-based e-Healthcare system
TL;DR: In PPDP, patients’ historical medical data are encrypted and outsourced to the cloud server, which can be further utilized to train prediction models by using Single-Layer Perceptron learning algorithm in a privacy-preserving way, and computation costs are several magnitudes lower than existing disease prediction schemes.
Journal ArticleDOI
Scalable and Privacy-Preserving Data Sharing Based on Blockchain
TL;DR: A trusted data sharing scheme using blockchain to prevent the shared data from being tampered, and the Paillier cryptosystem to realize the confidentiality of the sharing data is proposed.
Journal ArticleDOI
Quaternion polar harmonic Fourier moments for color images
TL;DR: Experimental results show quaternion polar harmonic Fourier moments can achieve an ideal performance in image reconstruction and invariant object recognition in noise-free and noisy conditions.
