Storage systems are widely used and have played a crucial rule in both consumer and industrial products, for example, personal computers, data centers, and embedded systems. However, such system suffers from issues of cost, restricted-lifetime, and reliability with the emergence of new systems and devices, such as distributed storage and flash memory, respectively. Information theory, on the ot...

In recent years, intra-hospital computerisation including picture archiving and communication system (PACS) and electronic medical chart system (EMCS) has been rapidly introduced in Japan. The current system has, however, encountered many problems, such as, storage format of images, quality of diagnostic monitors, and compatibility of PACS and EMCS introduced by multi-vendors. In 2003, Saitama ...

introduction: over the past few decades, two revolutionary approaches have emerged as a new form of medical education: electronic medical education and web-based medical education. a number of well-known medical institutions, such as harvard and johns hopkins used a wide range of cyberspace capabilities to increase their competitiveness. researchers have expressed that cyberspace will change he...

Medical information digitization makes the medical information storage and extraction more convenient. Medical image information security and copyright protection is also gradually being taken seriously, and some medical image watermarking has been applied. According to the characteristics of three-dimensional medical images, this paper proposes a robust zero-watermarking algorithm for medical ...

Digital watermarking is a technique of hiding specific identification data for copyright authentication. Most of the medical images are compressed by joint photographic experts group (JPEG) standard for storage. The watermarking is adapted here for interleaving patient information with medical images during JPEG compression, to reduce storage and transmission overheads. The text data is encrypt...

Because of the high compressibility of the medical images, data compression is desirable for digital storage despite the availability of inexpensive hardware for mass storage. A progressive transmission algorithm with automatic security ltering features for on-line medical image distribution using Daubechies' wavelets has been developed and is discussed in this paper. The system is practical fo...
