With rapid growth in computer network and information technology, a large number of copyrighted works now exist digitally as a computer files, and electronic publishing is becoming more popular. These improvements in computer technology increase the problems associated with copyright enforcement and thus future developments of networked multimedia systems(More)
Advances in wireless sensor network technologies have realized new opportunities to form Wireless Body Area Network (WBAN) for pervasive remote monitoring of the patients' vital signs at hospital and remote homecare environment, thereby improving healthcare system. The wireless physiological body sensor node is capable of sensing and processing the vital(More)
The security and authenticity of biomedical data are of the subjects of legal requirements. This paper proposes the use of digital watermarking to improve the security of biomedical signals transmitted over a wired or wireless network. The proposed scheme embeds a watermark sequence generated for each patient using the integer wavelet transform. Since for(More)
As electroencephalography (EEG) signals contain sensitive personal health information, it is generally a legal requirement to prevent their unauthorized access. For example, the HIPAA in the US requires that access to personal health information is limited to properly authorized individuals. In this paper, a chaos-based encryption method is proposed to(More)
A telemedicine system is described for monitoring the vital signs and general health indicators of patients with cardiac and diabetic conditions. Telemetry from wireless sensors and readings from other instruments are combined into a comprehensive patient health dataset. The data can be stored, accessed and displayed using mobile Internet communications(More)
This paper describes a practical development project to enable the monitoring of vital signs data obtained from patients located in remote rural locations. The data are gathered from a wireless network of sensors attached to a patient's body and stored locally for secure transmission over existing communication infrastructures to a hospital server.(More)
