Content based information retrieval in forensic image databases

This paper gives an overview of the various available image databases and ways of searching these databases on image contents. The developments in research groups of searching in image databases is evaluated and compared with the forensic databases that exist. Forensic image databases of fingerprints, faces, shoeprints, handwriting, cartridge cases, drugs tablets, and tool marks are described. The developments in these fields appear to be valuable for forensic databases, especially that of the framework in MPEG-7, where the searching in image databases is standardized. In the future, the combination of the databases (also DNA-databases) and possibilities to combine these can result in stronger forensic evidence.     

Y- STRs and forensic parameters in African populations

Short Tandem Repeat polymorphisms have been widely studied in the world, since specific databases are required to produce correct estimates of forensic statistical parameters. In this regard, Y-chromosome STRs have been studied mainly in Europe but are relatively scarce for sub-Saharan populations, despite these populations are represented in most of the Western countries. The aim of this work is to detect groups of populations with the lowest genetic variability within the African context. This allows to establish the relative homogeneity of Y-STRs databases for forensic casework and eventually to provide a wider insight into the African genetic history.     

Data registers in respiratory medicine: a pilot project evaluating compliance with privacy laws and the National Statement on Ethical Conduct in Research Involving Humans

This article reports on data from a small pilot survey evaluating the compliance of voluntary databases in respiratory medicine with privacy laws and the National Health and Medical Research Council's National Statement on Ethical Conduct in Research Involving Humans. The increasing complexity of privacy law, including the recent private sector amendments, creates many challenges for database administrators. The impact of privacy laws upon voluntary or non-statutory databases, and upon doctors reporting patient data to such databases, is far from straightforward. The article suggests way in which the law might be adapted in order to better facilitate the role of voluntary data registers in health research and public health surveillance, while still protecting the privacy of patient information. The article also briefly considers how database administrators might "future-proof" their existing data holdings to ensure compliance with legal and ethical standards.

Species identification using sequences of the trnL intron and the trnL-trnF IGS of chloroplast genome among popular plants in Taiwan

Forensic botanical comparison can be hampered by the lack of appropriate DNA databases. While DNA sequence databases for many mitochondrial loci have been established for the identification of animal species, less is known regarding the genomes of plants. We report on the use of the trnL intron and the trnL-trnF intergenic spacer (IGS) in the chloroplast genome and establish a DNA sequence database for plant species identification. The DNA sequences at these two loci from commonly encountered plants, including monocots and dicots, were aligned to establish a DNA database of local plants. The database comprises 373 individual sequences representing 80 families, 206 genera and 269 species. These plant species can be grouped to species level using both sequence and length polymorphisms at these loci. To validate the database for future forensic purposes, we sequenced 20 blind samples and searched the local database and the databases of GenBank and EMBL. Fifteen of these 20 samples used in blind trial testing matched their respective species from our local DNA database but only 6 matched species registered in the GenBank and EMBL databases. The sequences of two species used in the blind trial did not match any sequence registered in any of these databases. Cluster analysis was performed to demonstrate the family and genus distribution of samples. Neighbor-joining trees of the two DNA regions from 70 samples of the local database and 10 of the species used in the blind trials were constructed and clustered to both family and genus. The bootstrap values of the trnL intron were higher than most of those of the trnL-trnF IGS. The sequence database described in this study can be used to identify plant species using DNA sequences of the trnL intron and trnL-trnF IGS of chloroplast genome and illustrates its value in plant species identification.     

The "GeneTrustee": a universal identification system that ensures privacy and confidentiality for human genetic databases

This article describes a generic model for access to samples and information in human genetic databases. The model utilises a "GeneTrustee", a third-party intermediary independent of the subjects and of the investigators or database custodians. The GeneTrustee model has been implemented successfully in various community genetics screening programs and has facilitated research access to genetic databases while protecting the privacy and confidentiality of research subjects. The GeneTrustee model could also be applied to various types of non-conventional genetic databases, including neonatal screening Guthrie card collections, and to forensic DNA samples.     

A database right in search results? – An intellectual property right reconsidered in respect of computer generated databases

With much information available from open sources on the internet, computer generated databases have become commonplace. The question whether computer generated databases can be protected under the sui generis database right has hitherto received little attention. This article investigates this question and finds that the substantiality of investment, the definition of the rights holder and the interpretation of exclusive rights raise fundamental issues.     

Evidence in support of self-declaration as a sampling method for the formation of sub-population DNA databases

Well constructed sub-population databases are fundamental to the application of DNA-based forensic statistics. The size of such databases can affect the ability to examine adequately statistical or population genetic features, and the integrity of both the DNA profile and associated ethnicity information is also of importance. Use of short tandem repeat (STR) DNA profiling technology and the thoughtful construction of the governing legislation has seen large databases of DNA profiles collated for the four major sub-populations of New Zealand. Examination of the data illustrates the suitability of self-declaration as a means of categorizing samples on the basis of ethnicity.     

Y chromosome haplotypes in Central-South Italy: implication for reference database

One hundred and fifty individuals have been sampled across Central-South Italy and genotyped for Y chromosome STRs by PowerPlex Y system. Comparison with previous Italian databases revealed that majority of Y chromosome variation still need to be sampled. Identification of locus duplications, distribution of genetic variation and firstly identified alleles point to the necessity of more focused sampling strategies for reference databases.     

A nation's genes for a cure to cancer: evolving ethical, social and legal issues regarding population genetic databases

The advent of the human genome sequence has focused research on understanding underlying genetic links to complex diseases such as cancer, asthma and heart disease. In the past few years, individual countries, such as Iceland, Estonia, Singapore and the United Kingdom, have created national databases of their citizens' DNA for comparative research. Most recently, an international consortium including Nigeria, Japan, China and the United States launched a $100 million project called the International HapMap to map the human genome according to haplotypes, blocks of DNA that contain genetic variation. Such population genetic databases present challenging ethical, social and legal issues, yet regulation of genetic information has developed sporadically, from region to region, without a consistent international standard. Without a clear understanding of the consequences of genetic research in terms of individual and community-wide discrimination and stigmatization, genetic databases raise concerns about the protection of genetic information. This Note provides a survey of the evolving landscape of population genetic databases as a legislative and public policy tool for national and international regulators. It compares different approaches to regulating the collection and use of population genetic databases in order to understand what areas of consensus are formulating a foundation for an international standard. As the first population genetics project that will span multiple countries for the collection of DNA, the International HapMap has the potential to become an influential standard for the protection of population genetic information. This Note highlights issues among the national databases and the HapMap project that raise ethical, social and legal concerns for the future and recommends further protections for both individual donors and community interests.     

The governance of human genetic research databases in mental health research

The field of mental health offers a valuable context in which to examine new challenges presented by human genetic research databases to the legal, ethical and regulatory frameworks for human genetic research. Longitudinal prospective genetic research of psychiatric disorders often involves access to human genetic research databases and to stored tissue for future uses that cannot be specified at the time the patient consents to their collection. The potential of such research to contribute to an improved understanding and treatment of complex genetic diseases such as schizophrenia presupposes sound ethical, legal and regulatory frameworks to ensure public trust and preparedness to participate in such research. This article provides a brief overview of some of the ethical and legal challenges posed by human genetic research databases and their implications for how genetic research should be conducted in the field of mental health.     

Governing Genetic Databases: Challenges Facing Research Regulation and Practice

This paper reports on the initial findings of an interdisciplinary research project on the governance of human genetic databases in England and Wales. The number of biosample and information collections has expanded, yet considerable legal uncertainty surrounds their definition, collection, storage, management, and use which could inhibit research and clinical practice, while failing to protect the rights and interests of all stakeholders. We report some initial findings from the legal research and identify major challenges associated with defining 'genetic databases'. We identify a wide range of relevant instruments and regulatory actors, and suggest that none adequately addresses the challenges posed by contemporary research techniques or the'corporeal'and'informational'materials used in the genetic databases context. This preliminary analysis seriously questions the efficacy of the current regulatory framework and concludes that developing an appropriate governance framework for the creation, maintenance, and use of genetic databases requires the bringing together of legal analysis with good quality empirical evidence.     

Protection of databases in India and sui generis protection

Legal context: Historically, databases are protected under copyright law. India(which has been a major beneficiary of electronic commerce)provides copyright protection to databases. The adequacy ofthis protection is analysed in this paper, which considers thedevelopments in digital technology that make most of the databasemanufacturers susceptible to free-rider competition. The paperaims to demonstrate that adoption of the Feist doctrine by theIndian courts leads to inequitable results. The solution advocatedis the adoption of a sui generis legislation which clearly prescribesthe property rights and limitations, to database creators inIndia. Key points: The present legal environment in India grants protection todatabases under the Copyright Act 1957. The judiciary has interpretedthis protection utilizing the ‘sweat of the brow’theory as applied in Feist Publications, Inc. v Rural TelephoneService Co. The article argues that this is a thin layer ofprotection and acts as a significant deterrent to a databaseauthor's economic interests. The solution which the articlesuggests is a statutory sui generis database right. Practical significance: With the increased digitization of data, India is increasinglyseen as the back office of the world. This outsourcing of workto India has brought in an economic boom particularly in InformationTechnology Enabled Services. The creation and exploitation ofdatabases is a natural component of such services. Without thegranting of an adequate standard of protection to the authorsof the databases, the economic boom will not be sustainable.     

DNA typing in populations of mule deer for forensic use in the Province of Alberta

The present study involves the development of forensic DNA typing tests and databases for mule deer in the Province of Alberta. Two multiplex PCR reactions interrogating 10 loci were used to analyze samples from three populations of mule deer. Additionally, an amelogenin based sex-typing marker was used to determine the gender of samples. Results show that the tests and databases are appropriate for use in forensic applications. Additionally, the results indicate that there is little population structure in mule deer in Alberta and that no changes to management of this game species are suggested.     

Electronic databases: Protecting your investment – An analysis of the legal rights in electronic databases under UK law

Electronic databases are an important part of the information economy. They are now one of the key platforms for the distribution of information and other contents. The European Court of Justice, in November 2004, gave its first rulings on the scope of database right, introduced by Directive 96/9/EC on the legal protection of databases. These rulings significantly curtail the scope of that right, and limit the protection afforded to database producers under that Directive. The UK courts, in January of last year, handed down a judgment which has important implications for the copyright protection afforded database structures and to “look and feel” elements of database application software, and the scope of Section 50D of the Copyright, Designs and Patents Act 1988 (which sets out certain statutory permitted acts in relation to database use). This article looks at the implications of these judgments, it analyses some of the key legal rights that can apply to electronic databases, and the increased importance that rights of confidentiality and contract are likely to have on the commercialisation of electronic databases in light of these rulings.     

Analytical survey of restorative resins by SEM/EDS and XRF: databases for forensic purposes

Frequently in forensic cases, unknown substances must be identified. Automated databases can ease the burden of comparison as materials may be compared against many known standards in a relatively short period of time. It has been shown that dental resins can be named according to brand or brand group even in conditions as harsh as cremation. Databases are already in use for many materials, but no such database exists for dental resins. Thus, two databases were generated. One utilized a laboratory-based method, scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM/EDS), in conjunction with the Spectral Library Identification and Classification Explorer (SLICE) software. The other was based on portable X-ray fluorescence (XRF). The ability to perform database comparison with portable instrumentation can thus be brought directly to the field. Both the SLICE and XRF databases were evaluated by testing unknown resins. EDS is a well-established technique and the SLICE program was demonstrated to be a good tool for unknown resin identification. Portable XRF is a relatively new instrument in this regard and its databases have been constructed mostly for metal alloy comparison and environmental soil testing. However, by creation of a custom spectral library, it was possible to distinguish resin brand and bone and tooth from other substances.     

Pistol image retrieval by shape representation

Databases have been used to record data in forensic science, such as fingerprints, shoeprints, and photos. In traditional databases, we use “text” as the “keyword” for retrieving data (text-keyword retrieval); however, in some applications, “text” is not proper to describe the searching target, and in this case, “image” plays an important role. In this paper, we use “image features” as the “keywords”, and show its potential for building up a prototype of pistol image databases.In current firearm databases of forensic science, the retrieval method is still by text-keyword retrieval. For experienced forensic examiners, this kind of databases may satisfy their requirement. However, for people who have little gun knowledge, how can they find the possible gun candidates or similar guns in the databases, if there are not any available words or marks on the gun? In this paper, we try to retrieve similar pistol images by the pistol shape instead of “text-keyword”. This method can narrow down the searching range while identifying pistols by firearm databases.There are more than 300 pistol images in our pistol image database. From the experimental results, we can retrieve the similar pistol images in top five candidates for each pistol image.     

Attitudes towards police use of consumer/private DNA databases in investigations

Consumer DNA products, such as databases that allow the public to explore familial relationships, have recently been used by police to assist in investigations. This has moved the collection of DNA used in criminal investigations away from the limitations of criminal databases and has opened up ethical concerns regarding privacy and consent. This study explored public attitudes and support towards police use of consumer DNA databases in investigations to assess whether different crime types or moral and attitude alignments influenced the level of public support of police using these consumer products. An international survey of 438 adults, using theory and scales pertaining specifically to retributive punishment and attitudes towards law, courts and police, found that moral alignment and attitudes did influence the level of public acceptability towards police usage of these techniques and that support did vary based on crime type. This research found that higher levels of public support was given for the most serious case types explored (sexual assault and homicide). Participant support for police access to private DNA databases by case type was as follows; 83.5% for sexual assault, 83.2% for homicide, 85.2% for identifying unidentified human remains, 62.8% for robbery and 58.9% for illicit drug related cases. Small to medium effects sizes were observed for these results. Although these findings provided context towards public attitudes, further research specific to international attitude differences and variance between serious crime types and public acceptability could further develop these findings.
