Determining nanomaterials in food

2011

Abstract Nanotechnology has emerged as one of the most innovative technologies and has the potential to improve food quality and safety. However, there are a few studies demonstrating that nanomaterials (NMs) are not inherently benign. This review highlights some current applications of NMs in food, food additives and food-contact materials, and reviews analytical approaches suitable to address food-safety issues related to nanotechnology. We start with a preliminary discussion on the current regulatory situation with respect to nanotechnology in relation to foods. We cover sample preparation, imaging techniques (e.g., electron microscopy, scanning electron microscopy and X-ray microscopy),…

Review of the methods for the development of information security policies at organizations

2016

This thesis aims to have an overview of the current studies in the development of information security policy. The research is based on a systematical literature review. The study focuses on the development process of information security policy and other relevant issues in information security policy development within organizations. There are four research questions are proposed based on this topic: 1) what are the functions of information security policy; 2) what kind of stakeholders should be involved in the development of information security policy; 3) what is the information security policy lifecycle; 4) what are the methods in development of information security policy. The research…

Game theory and contemporary conflicts

2019

GAME THEORY AND CONTEMPORARY CONFLICTSThe article presents the application of game theory in the context of civil and military security. Game theory is used to study conflict situations involving more than one decision-maker. Special emphasis was given to the significant role of information in modern military operations. The article contains examples illustrating similarities between civil and military problems.

Transitions in European land-management regimes between 1800 and 2010

2015

Land use is a cornerstone of human civilization, but also intrinsically linked to many global sustainability challenges—from climate change to food security to the ongoing biodiversity crisis. Understanding the underlying technological, institutional and economic drivers of land-use change, and how they play out in different environmental, socio-economic and cultural contexts, is therefore important for identifying effective policies to successfully address these challenges. In this regard, much can be learned from studying long-term land-use change. We examined the evolution of European land management over the past 200 years with the aim of identifying (1) key episodes of changes in land …

A general framework for group authentication and key exchange protocols

2014

Published version of a chapter in the book: Foundations and Practice of Security. Also available from the publisher at: http://dx.doi.org/10.1007/978-3-319-05302-8_3 In this paper, we propose a novel framework for group authentication and key exchange protocols. There are three main advantages of our framework. First, it is a general one, where different cryptographic primitives can be used for different applications. Second, it works in a one-to-multiple mode, where a party can authenticate several parties mutually. Last, it can provide several security features, such as protection against passive adversaries and impersonate attacks, implicit key authentication, forward and backward securi…

Migrating from a Centralized Data Warehouse to a Decentralized Data Platform Architecture

2021

To an increasing degree, data is a driving force for digitization, and hence also a key asset for numerous companies. In many businesses, various sources of data exist, which are isolated from one another in different domains, across a heterogeneous application landscape. Well-known centralized solution technologies, such as data warehouses and data lakes, exist to integrate data into one system, but they do not always scale well. Therefore, robust and decentralized ways to manage data can provide the companies with better value give companies a competitive edge over a single central repository. In this paper, we address why and when a monolithic data storage should be decentralized for imp…

Terveydenhuolto ja kyberuhkat

2019

Kyberturvallisuusstrategian vision mukaan Suomen tulee kyetä suojaamaan elintärkeät toimintonsa kyberuhkaa vastaan kaikissa tilanteissa. Terveydenhuolto on yksi elintärkeistä toiminnoista. Terveystoimiala on kyberhyökkäysten top-5-listalla ensimmäisenä. Hyökkäysten keskeisin motivaatio on potilastietojen arvo pimeillä markkinoilla. Vuonna 2015 varastettiin yli satamiljoonaa potilastietoa, jotka sisältävät rikollisille arvokkaita tietoja, kuten luottokorttinumeroita, työnantajatietoja ja sairaushistoriatietoja. Tässä artikkelissa kuvataan terveydenhuoltoon liittyviä kyberuhkia, kyberhaavoittuvuuksia ja toteutuneita kyberhyökkäyksiä kybermaailman eri ulottuvuudet kattaen. Tarkastelussa käytet…
