As medical images are created, displayed, transmitted or stored in a digital form, there has been a growing interest in protecting the medical images against external/internal attackers. In this paper, we propose a dual watermarking method(DWM) to protect medical images in transmission/storage. As the proposed DWM provides both robustness and fragileness(More)
The Picture Archiving and Communication System(PACS) was introduced for computerization of the medical system and telediagnosis between the hospital. It is becoming possible to create, store, and transmit medical images via PACS. There has been a growing interest in protecting medical images with an enormous amount of information. To improve transmission(More)
Biometrics verification can be efficiently used for intrusion detection and intruder identification in video surveillance systems. Biometrics techniques can be largely divided into traditional and the so-called soft biometrics. Whereas traditional biometrics deals with physical characteristics such as face features, eye iris, and fingerprints, soft(More)
Due to increased terrors and crimes, the use of the video surveillance camera system is increasing. It has been operated for public interest such as prevention of crimes and fly-tipping by the police and local government, but private information such as faces or behavior patterns can be recorded in CCTV. When the recorded video data is exposed, it may cause(More)
— Since the increase of terrors and crimes, the demand of the video surveillance system is increasing. The video surveillance system has been operated for public interest by the police and local government. However private information such as faces or behavior patterns can be recorded in CCTV, it may cause the invasion of privacy. This paper proposes a(More)
Digital medical images assist specialists in improving their diagnostic efficiency and in treating diseases. For example, the chest Computed Tomography (CT) images help in diagnosing the lung disease. The chest CT scan generates multiple images of a patient’s lung. The size of the medical imaging data has increased with the usage of medical images. In a(More)
These days surveillance system has been developed into intelligent system that can judge and handle using human recognition technology that can recognize the people. In this paper, LDA-based face recognition algorithm for the intelligent surveillance system is proposed. While the existing face recognition algorithm uses the short distance images for(More)
Recently, the use of security surveillance system including CCTV is increasing due to the increase of terrors and crimes. However as the data recorded through the video surveillance system is exposed, the invasion of privacy is raised. The research on the technology of protecting privacy from the surveillance system in addition to these organizations is(More)
