Security of Nursing Care Information by Steganography Technology

Abstract

 It is important to use medical information system in order to offer nursing care service continuously. However, it is one of the most critical systems concerning security issues such as privacy protection and data integrity, too.

 The purpose of this study is to avoid leaking out the privacy and to keep security of network system. In th is paper, we especially propose to transmit data by using a steganography that is one of digital envelope technologies, what we call. We made this function up the nursing guidance system of decubitus care that we are now constructing. By means of covering nursing information data up with diseased image data, patients' privacy is protected. Further, by means of binding image data and text data, we are able to transfer the data easily.

 The system based on steganography will be a useful tool because we can send them as attachment files with electric mail.
