Telemedicine is the use of Information and Communication Technology (ICT) for clinical\nhealth care from a distance. The exchange of radiographic images and electronic patient health\ninformation/records (ePHI/R) for diagnostic purposes has the risk of confidentiality, ownership\nidentity, and authenticity. In this paper, a data hiding technique for ePHI/R is proposed. The color\ninformation in the cover image is used for key generation, and stego-images are produced with\nideal case. As a result, the whole stego-system is perfectly secure. This method includes the features\nof watermarking and steganography techniques. The method is applied to radiographic images.\nFor the radiographic images, this method resembles watermarking, which is an ePHI/R data system.\nExperiments show promising results for the application of this method to radiographic images in\nePHI/R for both transmission and storage purpose.
