An Usability Constraint Model & Information Preserving Watermarking Scheme for Novel Rights Protection of EMR System with Multivariate data

The Electronic Medical Records (EMR) is a set of application and workflow that digitizes the creation, collection, storage and management of patient information. The use of EMR enables physicians to do accurate and effective diagnosis. The interoperable EMR systems are becoming the top priority in the world. Acceleration in the use of electronic medical records may lead to an increase in personal health information theft, unauthorized access and illegal sale to third parties. In order to avert such a situation, the EMR data need to be right protected so that an unauthorized party might be sued in a court of law. The ownership rights protection of EMR dataset is possible through a well-known technique of watermarking. The challenges associated with watermarking EMR would be corrupt medical record that may lead to misdiagnoses and attacks for corrupting watermark. Thus a specialized model is proposed for ownership rights protection of EMR system with multivariate attributes having both numeric and non-numeric data using a usability constraint model and information preserving watermarking scheme. The watermarking process is modeled as a constrained optimization problem using particle swarm optimization (PSO).The decoding of watermark is done using a majority voting scheme.
