Abstract
The metadata representation in the context of data privacy is one of the biggest challenges in data security. The segregation of the data attributes for secure data retrieval as well as data storage is the primary motivation for this work. The metadata-based data retrieval is performed for providing a layer of protection on the actual data set and also for efficiently searching the location of encrypted data. The paper aims to provide a technique for representing the metadata of the encrypted e-health data for a secure data retrieval process. The hierarchical representation of metadata helps in retrieving the data in an efficient way so that access to the sensitive information could be controlled. The paper proposes a novel technique for metadata design for secure data retrieval. E-health data is fragmented over multiple servers based on sensitive attribute and sensitive association. A brief overview of the data protection and data retrieval techniques with respect to the proposed metadata representation is also presented.
