Ruby Conference 2011 THE SAFE INFORMATION CONTROL TOOL WHICH ACHIEVES THE HIGH COMPRESSION, HIGH SECURITY, AND LOW LOAD USING RUBY ON RAILS JUN ROKUI SHIMANE UNIVERSITY

RESEARCH OUTLINE 3D Color Barcode We developed 3D Color Barcode in 2007. Large capacity data can be saved compared with the existing bar code. 3D Color Barcode has high encryption capability. We considered 3D Color Barcode as print media. Technoproject, Ltd. found out the charm as electronic media to 3D Color Barcode. Since Technoproject, Ltd. was developing the distance medical service system, he was looking for the electronic media for communicating medical information. We are performing the joint research aiming at electronic media use of 3D Color Barcode from 2010.

THE COMPRESSION EFFECT OF THE MEDICAL IMAGE The compressibility comparison with ZIP, lossless 20 serial MRI images JPEG, and the proposing method compress 3D color barcode based method has achieved compressibility high not less than 14% compared with ZIP. It has achieved compressibility high not less than 5% compared with lossless JPEG. Since there are also few computational complexities, this technique is a practical technique.
