Biometric System Vulnerability as a Compromising Factor for Integrity of Chain of Custody and Admissibility of Digital Evidence in Court of Justice: Analysis and Improvement Proposal
No full textBiometric systems play an important role in digital investigation process as a important factor of authentication and verification applications, since they are strongly linked to the holder of a biometric traits and possible suspect. Thus it is important that biometric systems can be designed to withstand attacks when employed in security-critical applications, especially in unattended remote applications such as energy plants, access to borders at airports, ecommerce etc. Biometric recognition either raises important legal issues of remediation, authority, and reliability, and, of course, privacy. The standard assumptions of the technologists who design new techniques, capabilities, and systems are very different from those embedded in the legal system. Legal precedent on the use of biometric technology is growing, with some key cases going back decades and other more recent cases having raised serious questions about the admissibility of biometric evidence in court. In this paper authors is about to explain influence of reliability of biometric system on general acceptance of digital evidence in Court of Justice process. Through paper authors are also about to propose vulnerability assessment of biometric system as improvementfactor of reliability of existing methodology for preserving chain of custody of digital evidence called DEMF (Digital Evidence Management Framework). Improvement proposal is presented as an introduction of phase of biometric vulnerability evaluation methodology within proposedframework called APDEMF (Admissibility procedure of DEMF). Using UML (Universal Modeling Language) modeling methodology authors are about to represent a APDEMF framework which will describe essential phases of the same process
Technical, Legal, Economic and Social Aspects of Biometrics for Cloud Computing
No full textThis article addresses technical, legal, economic and social aspects of biometrics for cloud computing, featuring application example, gains of such solution, current laws, directives and legislation for biometrics and cloud computing. It is primarily based on Slovenian example due to common general EU legislation in the field of cloud computing and biometrics. Authentication on the Internet is still mainly done using passwords, while biometrics is practically not used. It is commonly known that everything is moving to the cloud and biometrics is not an exception. Amount of biometric data is expected to grow significantly over the next few years and only cloud computing is possible to process such amounts of data. Due to these facts and increasing security needs, we propose and implement the use of biometry as a service in the cloud. A challenge regarding the use of biometric solutions in the cloud is the protection of the privacy of individuals and their personal data. In Slovenia privacy legislation is very strong, it permits usage of biometrics only for very specific reasons, but we predict that big players on the market will change this fact globally. One of the important reasons for that is also the fact that biometrics for cloud computing provides some strong benefits and economic incentives. Proper deployment can provide significant savings. Such solutions could improve people’s quality of life in terms of social development, especially in sense of more convenient, safer and reliable identification over multiple government and non-government services
A Case Study of Software Product Line for Business Applications Changeability Prediction
No full textThe changeability, a sub-characteristic of maintainability, refers to the level of effort which is required to do modifications to a software product line (SPL) application component. Assuming dependencies between SPL application components and reference architecture implementation (a platform), this paper empirically investigates the relationship between 7 design metrics and changeability of 46 server components of a product line for business applications. In addition, we investigated the usefulness of Platform Responsibility (PR) metric as an indicator of product line component changeability. The results show that most of the design metrics are strongly related to the changeability of server component and also indicate statistically significant correlation between Maintainability Index (MI) and PR metric. The assessment is based on a case study of the implementation of the product line for business applications in a financial institution. The results show that PR metric can be used as good predictor of changeability in the software product line environment.
Intention to Use and Variables Influencing Intention to Use Electronic Government Services Among Citizens
No full textEach organization should be aiming at higher efficiency. Government institutions should not make an exception.Business processes of today’s government institutions are extremely influenced by modern ICT and user acceptance plays a pivotal role in success of all ICT projects. As government tends to design and launch online services without actually measuring citizens’ needs, understanding citizens’ (taxpayers’) needs is becoming crucial for government institutions.In this paper, a range of earlier studies have been critically analyzed and comparedto provide anintegrated model that can identify factors which could influence adoption of e-government services. The goal of this article is to study citizens’ demand for different levels of electronic government service and to find factors which influence the adoption ofthese same services.This study integrates variables from technology acceptance model (TAM) and trustworthiness model.Analysis of the results indicates that there is a significant positive relationship between Trust in Internet, Perceived usefulness, Perceived ease of use andtheIntentionto use. Implications for further research are discussed
Elements of Resource Representation in Institutional Repositories: a Bibliographic Review
No full textThis review focuses on identifying how the literature studies the existing problems in the Resource Representation (RR) of Institutional Repositories (IR). RR is a process of recording in a persistent manner a set of data (metadata) as a synthesis and replacement of the "real" object, to allow its identification, retrieval and dissemination. RR is defined by certain elements: resources, metadata schema, storage and cataloging. On the other hand, IRs are based on functional processes according to the material that is deposited and the ISO 14.721 standard: ingest, storage, cataloging,indexing, search engine and browsing. The results of this review show that identifying the problems found in these elements and functional processes is not a subject of study for the researchers, which leads to a vacant area in this field, and in this way to solve some of the problems present in the RI, from the point of view of functional elements and processes
Approximation of unit-hypercubic infinite antagonistic game via dimension-dependent irregular samplings and reshaping the payoffs into flat matrix wherewith to solve the matrix game
No full textThere is suggested a method of approximating unit-hypercubic infinite antagonistic game with the matrix game and the corresponding solution in finite strategies. The method is based on dimension-dependent irregular samplings over the game kernel. Numbers of the sampling points and their coordinates are chosen due to the stated conditions. If the sampled kernel is not the flat matrix them the multidimensional payoff matrix is reshaped into the flat one wherewith to solve the matrix game. The reshaping is a reversible matrix map. The concluding step of the approximation is in checking the finite solution consistency. Consistency can be weakened, and consistency can be checked at some rank corresponding to a natural number. The higher rank of the finite solution consistency is, the wider neighborhood of the sampling numbers at which the solution properties are monotonic-like
From the Editor

We are continuing to publish papers from the wide scope of information and organizational sciences from the computer science to the organizational systems.As a new JIOS editor I would like to introduce myself thank to the former editor prof. Neven Vrček not only for the help in my first JIOS issue, but for all things he did for JIOS while he was in charge. I really think that JIOS as it is today is mostly his credit, as anyone who compare the journal today and before his mandate can easily see. He improved JIOS in every sense, in international recognition, quality of papers, and technical design. I can only hope that I will be as succesful as he was and that I will develop as good relationship with authors, reviewers, editorial and publishing board as he had.

I really hope you will enjoy in reading this issue of JIOS and that you will find the papers in it interesting and useful
Applying Genetic Algorithms and RIA technologies to the development of Complex-VRP Tools in real-world distribution of petroleum products
No full textDistribution problems had held a large body of research and development covering the VRP problem and its multiple characteristics, but few investigations examine it as an Information System, and far fewer as how it should be addressed from a development and implementation point of view. This paper describes the characteristics of a real information system for fuel distribution problems at country scale, joining the VRP research and development work using Genetic Algorithms, with the design of a Web based Information System. In this paper a view of traditional workflow in this area is shown, with a new approximation in which is based proposed system. Taking into account all constraint in the field, the authors have developed a VRPWeb-based solution using Genetic Algorithms with multiple web frameworks for each architecture layer, focusing on functionality and usability, in order to minimizing human error and maximizing productivity. To achieve these goals, authors have use SmartGWT as a powerful Web based RIA SPA framework with java integration, and multiple server frameworks and OSS based solutions,applied to development of a very complex VRP system for a logistics operator of petroleum products
