Bio-signal data sharing security through watermarking: a technical survey

Due to smart healthcare systems highly connected information and communications technologies, sensitive medical records are easily transmitted over the networks. However, stealing of data is increasing crime every day greatly impact on financial loss. In order this, researchers developing various cost-effective bio-signal based hiding techniques for applications. this paper, we first introduce aspects along with major properties, generic embedding extraction process, recent This survey provides a comprehensive techniques, their new trends solving challenges in real-world Then, notable techniques. The summary some terms objective, type hiding, methodology database used, performance metrics, important features, limitations also presented tabular form. At end, discuss issues research directions explore promising areas future research.
