For the patients' privacy, secure access control of medical images is essentially necessary. In this paper, two types of Region of Interest (ROI)-based selective encryption schemes are proposed, which concentrate on the security of crucial parts in medical images. The first scheme randomly inverts the most significant bits of ROI coefficients in several high frequency subbands in the transform domain, which only incurs little loss on compression efficiency. The second scheme employs a symmetric key encryption to encrypt selectively the ROI data in the final code-stream, which provides sufficient confidentiality. Both of two schemes are backward compatible so as to ensure a standard bitstream compliant decoder so the encrypted images can be reconstructed without any crash.

From public insecurity, access of wealth, alteration of population structure, and changes of security recognition, physical security has been continuously developed and changed. In these days, typical systems for physical security are unmanned security system using telephone network and security equipment, image recognition system using DVR and camera, and access control system by finger print recognition and RFID cards. However, physical security system is broadening its domain towards ICT based convergence with networked camera, biometrics, individual authentication, and LBS services. This paper proposes main technical trends and various security convergences for future physical security services by classifying the security categories into 3 parts; Individual security for personal protection, IT Convergence for large buildings, and Homeland Security for omni-directional security.

Recently, SUA(Sudden Unintended Acceleration) are increasingly occurred. However, all the responsibilities of SUA are accepted by an innocent driver despite of painful results due to mystery of accurate cause. If a driver raises this kind of trouble to the corresponding manufacturer, the automaker collects EDR installed in that vehicle and provides the result of their analysis as it turns out most of the analysis results were diagnosed "there is nothing wrong with the car". In this trend, the technology to protect drivers' position from SUA should be developed. In this study, the researchers aimed to develop a black box system that collects additional data from throttle valve which is considered as one of major causes of SUA accidents, in order to explain cause of SUA and defend innocent drivers.
