DNA methylation is emerging as an attractive marker providing investigative leads to solve crimes in forensic genetics. The identification of body fluids that utilizes tissue-specific DNA methylation can contribute to solving crimes by predicting activity related to the evidence material. The age estimation based on DNA methylation is expected to reduce the number of potential suspects, when the DNA profile from the evidence does not match with any known person, including those stored in the forensic database. Moreover, the variation in DNA implicates environmental exposure, such as cigarette smoking and alcohol consumption, thereby suggesting the possibility to be used as a marker for predicting the lifestyle of potential suspect. In this review, we describe recent advances in our understanding of DNA methylation variations and the utility of DNA methylation as a forensic marker for advanced investigative leads from evidence materials.

We propose an Opto-Digital hybrid fingerprint Identification system based on the binary phase extraction joint transform correlator(BPEJTC) for validation and security yerification. It is shown that since the BPEJTC provides higher peak-to-sidelobe ratio than that of the conventional JTC and does not cause correlation peaks due to intra-class association, this system is well-adaptive to the multiple object environments. Experimental results show that this system has a good performance in the presence of multiple images and the variations of the same person.

The aim of this study is to analyze the intrinsic meaning of housing according to meaning of ritual space in Korean housing. At a traditional housing the rites give a sacred characteristic and grade of ranks to space. According to rites Malu(Dae-Chung) is a male's space and An-Bang is a female's space. At a present housing the central characteristic of An-Bang and sexual division of space are weakened and the space of dead person is disappered. But the rites and ritual space give sacred characteristic stability and identification in housing.

In this paper, we introduce a new technology to extract the unique features from an iris image, which uses scale-space filtering. Resulting iris code can be used to develop a system for rapid and automatic human identification with high reliability and confidence levels. First, an iris part is separated from the whole image and the radius and center of the iris are evaluated. Next, the regions that have a high possibility of being noise are discriminated and the features presented in the highly detailed pattern are then extracted. In order to conserve the original signal while minimizing the effect of noise, scale-space filtering is applied. Experiments are performed using a set of 272 iris images taken from 18 persons. Test results show that the iris feature patterns of different persons are clearly discriminated from those of the same person.

We propose an individual identification method using a single-lead electrocardiogram signal. In this paper, lead I ECG is measured from subjects in various physical and psychological states. We performed a noise reduction for lead I signal as a preprocessing stage and this signal is used to acquire the representative beat waveform for individuals by utilizing the ensemble average. From the P-QRS-T waves, features are extracted to identify individuals, 19 using the duration and amplitude information, and 16 from the QRS complex acquired by applying Pan-Tompkins algorithm to the ensemble averaged waveform. To analyze the effect of each feature and to improve efficiency while maintaining the performance, Relief-F algorithm is used to select features from the 35 features extracted. Some or all of these 35 features were used in the support vector machine (SVM) learning and tests. The classification accuracy using the entire feature set was 98.34%. Experimental results show that it is possible to identify a person by features extracted from limb lead I signal only.

This paper presents a new human identification algorithm using partial features of the uncovered portion of face when a person wears a mask. After the face area is detected, the feature is extracted from the eye area above the mask. The identification process is performed by comparing the acquired one with the registered features. For extracting features SIFT(scale invariant feature transform) algorithm is used. The extracted features are independent of brightness and size- and rotation-invariant for the image. The experiment results show the effectiveness of the suggested algorithm.

The Resident Registration Number(RRN) system has been effectively acted as a national identification system since it was enforced. On the other hand, there are some problems such as leakages of personal informations including RRNs on a large scale and each RRN makes a pair with each person in all areas of the society. Nevertheless leakages of them might cause a big damage, there is no radical countermeasure for they are never changed in actual fact. In Republic of Korea, a RRN acts as a primary key of a database, so it has to be protected by severing the connectivity between leaked RRNs and the other personal data. In this paper, the Unconnected Random Personal Identification Number system is proposed for preventing damage of data spills by removing a dependency which the RRN has. Furthermore, this paper suggests the solutions against some potential issues in the system.

Customized sleep care service needs to be provided differently for individuals since individual has different degree of sleep disorder. Because the brainwave data shows unique waveform characteristics for each person, this characteristic can be used to identify individuals. Personal identification provides an important role in enabling customized services. When you blink, you can obtain brain wave characteristics by measuring the area of the frontal lobe. Therefore, a real-time personal identification algorithm based on blinking EOG for customized sleep care service is proposed in this paper. For evaluation, 10 individuals were tested for personal identification accuracy. The results of the experiment confirmed that a maximum accuracy of 93% were taken. Algorithms can be developed by reflecting characteristics such as changes in the external environment in the future.

The white stick mainly used for visually impaired person has difficulty in providing location information and effective countermeasures for emergency situations encountered during walking as well as detecting floating obstacles on the ground. In this paper, we propose a machine-to-machine based intelligent walking assistance system for safe and convenient walking of the visually impaired. The proposed system consists of a walking assistance stick used by the visually impaired and a server supporting multiple stick users in remote places through mobile communication networks. The stick equipped with ultrasonic sensors, GPS(global positioning system) receiver and vibrator not only detects floating obstacles, but also offers stick users with present location identification utilizing a text-to-voice conversion technology. Besides providing geographic information, the server notifies the emergency locations of users to guardian and aid agency, and it provides log information during walking such as the place, time and the number of accidents. Test results with a developed prototype system have shown that the system properly performs the functions and satisfies overall system performance.

The article aims at studying the institution of human rights in an ever-evolving world in the context of the interdisciplinary approach. The main scientific method was deduction that allowed examining the specific interdisciplinary approach in relation to the institution of human rights on the global scale. To solve the issue set, it is necessary to study legal foundations and features of the interdisciplinary approach to the institution of human rights in the modern world. The article proves there is no theoretical anthropological understanding of the institution of human rights. It has been concluded that the appeal to anthropological jurisprudence requires the identification of the initial theoretical and methodological principles, parameters and axioms of cognition, the integration of a person into the subject field of legal science, linking jurisprudence with the chosen external environment (philosophy, sociology, theology, etc.), predetermining the existence (understanding) of a person, causing qualitative differences and the structure of subject-methodological phenomena. In addition to the identification of such hypotheses, prerequisites and axioms, the basic method (principle) of cognition and its heuristic potential are also being searched (defined). The terminological designation of the formed subject-methodological phenomenon (legal anthropology, anthropology of law, anthropological approach, etc.) reveals its role in the system of interdisciplinary relations of legal science.
