Seven years after the Japanese government abolished fingerprinting of foreign nationals due to an unusual display of discontent in civil society, it has decided to amend its immigration laws (改正入管法) to allow, once more, for fingerprinting and photographing of foreign nationals, no matter their visa or residence status. In blatant contradiction with Japanese law, which makes it illegal to fingerprint anyone that has not been charged with a crime, this controversial measure is weakly justified by stating it will help to “prevent the occurrence of acts of terrorism against Japan.” However, with the exception of the Japanese Embassy hostage crisis in Lima, Peru, Japan has never suffered a terrorist act that didn’t involve Japanese nationals solely. The arrests that followed the Aum Shinrikyou’s (オウム真理経) fiendish Tokyo sarin gas incident lead approximately twenty Japanese nationals to be tried and convicted by the justice system, but none of the cult’s internationals members were ever found to be involved in the attacks. Similarly, the infamous Japanese Red Army (日本赤軍), which hijacked airplanes, bombed and stormed company facilities and embassies, and murdered civilian bystanders indiscriminately, perpetrated thirteen terrorist acts between the 1970s and the 1980s. And yet, only two on them were committed on Japanese soil, while the other eleven were committed abroad; in every case, nonetheless, the participants involved in the attacks were solely Japanese nationals.
The Japanese word for a stranger (他人) is an “other person.” Foreigners (外国人, “outside country people”), likewise, are usually called gaijin (外人), “outside people” or “outsider,” in informal circumstances. The Japanese scholar Ohsawa Masachi has forwarded that the Aum sect “can be seen as an extreme reflection of Japanese society in general,” since it “mirrors the same type of fear toward the ambivalent ‘other’ common within the Japanese population.” For Ohsawa, that fear of the ambivalent ‘other’ is “a symptom of the social disintegration brought forth by advanced capitalism,” and in that manner “not particular to the Japanese, but rather reflected in many ethnic nationalisms and religious fundamentalisms of contemporary global society.” Nowadays, when globalization leads us inevitably to attempt to constructively deal with the intricacies of multicultural contexts, the return of undeniable racisms and state-sponsored discriminatory policies must be carefully analyzed and protested.

Feature Extraction from Vein Images using Spatial Information and Chain Codes

Exploiting the specific near infrared light absorption properties of blood, the capture procedure for this biometric characteristic is convenient and allows contact-less sensors. However, image skeletons extracted from vein images are often unstable, because the raw vein images suffer from low contrast. We propose a new chain code based feature en- coding method, using spatial and orientation properties of vein patterns, which is capable of dealing with noisy and unstable image skeletons. Chain code comparison and a selection of preprocessing methods have been evaluated in a series of different experiments in single and multi-reference scenarios on two different vein image databases. The experiments showed that chain code comparison outperforms minutiae-based approaches and similarity based mix matching.
Biometric Cryptosystem Involving Two Traits and Palm Vein as Key

Moreover the concept of cryptosystem is involved , where one of the biometric trait – the palm vein itself acts as a key to utilise the stored template database. The main idea in using one of the biometric trait as a key is that under any circumstance no two palm veins match unless it belong to same person. It is a valid key which no one can steal or misuse.
Sense and Security - A Comparative View on Access Control at Airports <2011>

Is there a dominant (visual, haptic, gustatory, olfactory or acoustic) culture of evidence? The present contribution approaches the applied side of sensory research. Looking at the case of airport security it reconsiders a number of changes carried out during the last decade. Envisaging the production of security as a matter of sensory perception, it goes beyond a polemical appreciation of these modifications. Instead of debunking some unspecified false sense of security, it shows multiple senses of security at work. Describing how sensory data are isolated, amplified, transformed, and re-combined during the process of security screening, special emphasis is given to the actual location of control activities and to the issue of storage of information. As a result, two modes of access control are found to persist and termed “laboratory check” and “biometric guardianship”. While the former, isolating sensory data, is local and allows for reversibility, the latter, blending local sensory practices with biometric information captured elsewhere (and stored), is irreversible.

If surveillance technologies are to be democratically controlled, then knowledge of these technologies is required. What do they do? How do they work? What are the costs? Yet gaining this knowledge in the context of a new surveillance technology such as biometrics can be problematic, because no settled definition exists. Competing versions of biometrics appear in both public and governmental discourse on the technology: different ideas about how often it fails, where it can be used and even what it does.
This paper is an exploration of how these different versions compete with each other, and how knowledge about a new surveillance technology such as biometrics is thus constructed. Through reference to original research in the context of the use of biometrics in the UK, points of stability and instability in the definition of biometrics are identified, and some of the processes through which instable definitions become stable are tracked.
From this empirical story, conclusions are drawn both for the process of construction of the meaning of technologies, and the general practice of surveillance in modern society. In particular, this paper aims to show how notions such as democratic control (central to the legitimation of state surveillance) become problematic when the very meaning of a technology is negotiable.

It refers to the automated method of verifying a match between two human fingerprints. It is essentially a challenging pattern recognition problem where two competing error rates: the False Accept Rate (FAR) and the False Reject Rate (FRR) need to be minimized. Advancement of computing capabilities led to the development of Automated Fingerprint Authentication Systems (AFIS) and this led to extensive research especially in the last two decades. In this paper, we attempt to give a comprehensive scoping of the fingerprint recognition problem and address its major design and implementation issues as well as give an insight into its future prospects.
Biometrics in Pharma: Politics and Privacy

The Drug Enforcement Agency (DEA) has announced the implementation of the use of both computerized and biometric security protocols in the electronic prescription of controlled substances. Electronic prescriptions which were up until this point not allowed to be prescribed by electronic means will now be easier for physicians and the DEA to monitor and prescribe.
This paper will examine the various practical, political, and privacy issues as well as the potential benefits of the use of biometric information for the prescription of narcotics and other controlled substances. The proposed changes will build in non-repudiation and improve accountability, while introducing problems such as delegation, privacy, cost, and information security. Another consequence of strong biometric authentication is false acceptance and false rejection rates. Not only are there annoyances due to false reject rates, there are serious medical consequences when a drug cannot be obtained due to failed biometric authentication.

As studies slowly explore the effects of adding elements of variation into the data they have met challenges in achieving granular statistical significance due to the limited size of their datasets. In this study, we aim to create a classification framework that is robust to non-studio, uncontrolled, real-world images. We show that the fusion of separate linear classifiers trained on smart-selected local patches achieves 90% accuracy, which is a 5% improvement over a baseline linear classifier on a straightforward pixel representation. These results are reported on our own uncontrolled database of 26,700 images collected from the Web.
An Exploration of Gender Identification Using Only the Periocular Region

This region of the face is of particular interest when trying to identify a person whose face is partially occluded. We propose the novel idea of applying the information obtained from the periocular region to identify the gender of a person, which is a type of soft biometric recognition. We gradually narrow the region of interest of the face to explore the feasibility of using smaller, eye-centered regions for building a robust gender classifier around the periocular region alone. Our experimental results show that at least an 85% classification rate is still obtainable using only the periocular region with a database of 936 low resolution images collected from the web.
