Technical Briefing: Hands-On Session on the Development of Trustworthy AI Software
2021
Following various real-world incidents involving both purely digital and cyber-physical Artificial Intelligence (AI) systems, AI Ethics has become a prominent topic of discussion in both research and practice, accompanied by various calls for trustworthy AI systems. Failures are often costly, and many of them stem from issues that could have been avoided during development. For example, AI ethics issues, such as data privacy are currently highly topical. However, implementing AI ethics in practice remains a challenge for organizations. Various guidelines have been published to aid companies in doing so, but these have not seen widespread adoption and may feel impractical. In this technical …
A Survey on Privacy in Decentralized Online Social Networks
2018
Decentralized Online Social Networks (DOSNs) have recently captured the interest of users because of the more control given to them over their shared contents. Indeed, most of the user privacy issues related to the centralized Online Social Network (OSN) services (such as Facebook or Google+) do not apply in the case of DOSNs because of the absence of the centralized service provider. However, these new architectures have motivated researchers to investigate new privacy solutions that allow DOSN’s users to protect their contents by taking into account the decentralized nature of the DOSNs platform. In this survey, we provide a comprehensive overview of the privacy solutions adopted by…
Privacy violations in Riga open data public transport system
2016
Over the recent years public transportation systems around the world have been migrating to digital ticketing solutions. This paper investigates security and privacy aspects of the one such system implemented by Riga municipality called e-talons by analysing published open data containing ride registrations.
Computing Platform for Virtual Economic Activities Index
2018
The authors enter three economic activity indices, which are calculated from the data in the virtual space on basis of Mobile Operator Call Description Records, Internet Log Files and News Portal audience textual comments and remarks analysis. The article provides the computing facility and the software specification for the Big Data computational platform. Indicates the need to comply this platform with strategy of data privacy requirements solutions and the visualization of results with data geographical mapping.
Contributions from ADBIS 2018 workshops
2018
The ADBIS conferences provide an international forum for the presentation of research on database theory, development of advanced DBMS technologies, and their applications. The 22nd edition of ADBIS, held on September 2–5, 2018, in Budapest, Hungary, includes six thematic workshops collecting contributions from various domains representing new trends in the broad research areas of databases and information systems.
Discovery privacy threats via device de-anonymization in LoRaWAN
2021
LoRaWAN (Long Range WAN) is one of the well-known emerging technologies for the Internet of Things (IoT). Many IoT applications involve simple devices that transmit their data toward network gateways or access points that, in their turn, redirect data to application servers. While several security issues have been addressed in the LoRaWAN specification v1.1, there are still some aspects that may undermine privacy and security of the interconnected IoT devices. In this paper, we tackle a privacy aspect related to LoRaWAN device identity. The proposed approach, by monitoring the network traffic in LoRaWAN, is able to derive, in a probabilistic way, the unique identifier of the IoT device from…
A practical framework for data management processes and their evaluation in population-based medical registries.
2013
We present a framework for data management processes in population-based medical registries. Existing guidelines lack the concreteness we deem necessary for them to be of practical use, especially concerning the establishment of new registries. Therefore, we propose adjustments and concretisations with regard to data quality, data privacy, data security and registry purposes.First, we separately elaborate on the issues to be included into the framework and present proposals for their improvements. Thereafter, we provide a framework for medical registries based on quasi-standard-operation procedures.The main result is a concise and scientifically based framework that tries to be both broad a…
Privacy handling for critical information infrastructures
2013
This paper proposes an architecture and a methodology for privacy handling in Critical Information Infrastructures. Privacy is in this respect considered as both the risk of revealing person-sensitive information, for example from critical infrastructures in health institutions, but also to identify and avoid leakage of confidential information from the critical information infrastructures themselves. The architecture integrates privacy enhancing technologies into an enterprise service bus, which allows for policy-controlled authorisation, anonymisation and encryption of information in XML elements or attributes in messages on the service bus. The proposed methodology can be used to identif…
Crisis of Privacy and Sacrifice of Personal Data in the Name of National Security: The CJEU Rulings Strengthening EU Data Protection Standards
2017
Snowden’s surveillance revelations in 2013 raised the issue of privacy and security in the public spotlight. These revelations underlined the need for strong data protection framework. At the same time, the pressing demand to address security concerns and the threat of terrorist attacks might weaken privacy and data protection standards. Two landmark judgments of the Court of Justice of the European Union (the CJEU), namely, the Digital rights Ireland judgment which invalidates Data Retention Directive, and the Schrems judgment which invalidates Safe Harbour Decision forming a legal basis for transatlantic data transfers are of great significance in strengthening the rights to privacy and d…
A model of Cyber Threat Information Sharing with the Novel Network Topology
2021
The digitized environments are particularly vulnerable to various attacks. In such a situation of a security attack, detecting and responding to attacks require effective actions. One of the most significant ways to improve resilience to security attacks is to obtain accurate and timely situational aspect of the security awareness. The efficient production and utilization of situation information is achieved by sharing information with other actors in the information sharing network quickly and reliably without compromising the confidential information of one's own organization. At the same time, it should also be possible to avoid a flood of irrelevant information in the sharing network, w…
