A cryptographic role-based access control model for electronic health record (EHR) systems uses location-and biometrics-based user authentication and a steganography-based technique to embed EHR data in electrocardiography (ECG) host signals. lectronic health record (EHR) systems offer more effi cient means of delivering quality-ensured healthcare services(More)
Cognitive Radio Networks have recently attracted attention because of high efficiency and throughput performance. They transmit (1) repetitively collected readings (e.g. monitoring) and (2) highly confidential data (e.g. geometric location). However, the privacy and the authenticity of the transmitted data are major challenges. This paper proposes a novel(More)
