— This article provides a comprehensive overview of the most common methods of medical images watermarking. It describes the watermarking of RONI (Region of Non Interest), Reversible watermarking and Zero watermarking. Main advantages and disadvantages of each method are mentioned and the causes of small watermarking methods deployments in securing medical image data are discussed. Based on this analysis, paper proposes a method for appropriate combining of two existing methods by making use of positive and eliminating negative properties of both methods.
