The demand for mobile terminals to participate in data services is increasingly vital. The General Data Protection Regulation (GDPR) has established several principled requirements for data services. Existing studies focusing on data service put emphasis on data privacy and accessibility. However, they face challenges in achieving data forgetability and portability on mobile devices under GDPR and...Show More
Cross-institutional Electronic Medical Records (EMRs) sharing significantly improves healthcare quality and reduces costs. Current EMRs are often stored on cloud servers and protected by Attribute-based Encryption (ABE) for access control. Cross-institutional sharing allows doctors to request EMRs access from target Healthcare Institutions (HIs) through attribute-based collaboration, enabling flex...Show More
This paper proposes a privacy preserving scheme for data security in the video surveillance. We firstly separate the foreground for each video frame, and obscure the separated human object by motion blur. For secure storage, each blurred foreground object is encrypted into N shares by visual cryptography, and stored into different servers. Each share is fully confidential and does not convey any m...Show More
This paper proposes a semi-fragile digital watermarking scheme for image tamper localization and self-recovery. Firstly, the authentication watermark is generated for tampered area localization. After that, for content recovery, the recovery watermark is calculated from high frequency band with redundancy free. Then, for the two type of watermarks, the DWT-based watermark embedding method makes ou...Show More
