Lawyers, laboratories, auditors or banks often need data containing sensitive personal information to provide their services. Examples of sensitive services include genetic testing, paternity testing, STD testing, credit scoring or legal advice. The processing of personal data, especially when providing services involving sensitive data such as hea...

Coraz większą popularność zyskuje usługa predykcji za pomocą sieci neuronowych. Model ten zakłada istnienie serwera, który za pomocą wyuczonej sieci neuronowej dokonuje predykcji na danych otrzymanych od klienta. Model ten jest wygodny, ponieważ obie strony mogą skupić się na rozwoju w swojej specjalizacji. Wystawia on jednak na ryzyko utraty prywa...

This paper proposes an improved monitoring and measuring system dedicated to industrial infrastructure. Our model achieves security of data by incorporating cryptographical methods and near real-time access by the use of virtual tree structure over records. The currently available blockchain networks are not very well adapted to tasks related to th...

Similar problems have not prevented electronic money from becoming widely used; therefore, the solutions for electronic money should also help solve the i-voting problem. Particularly, blockchain technology enabled creating secure systems without a central authority. Blockchains guarantee integrity and censorship resistance; however, voting process...

Bitcoin wprowadził innowację na wielu płaszczyznach. Jako pierwszy rozwiązał problem osiągania konsensusu w sieciach otwartych, stworzył zagadkę ekonomiczną w postaci globalnej waluty deflacyjnej, pozwolił na transfer pieniędzy tym, którzy wcześniej byli wykluczeni bankowo, ale przede wszystkim stworzył fundamenty pod platformę zdecentralizowanego...

Information-centric networks struggle with content poisoning attacks (CPAs), especially their stronger form called Fake Data CPA, in which an intruder publisher uploads content signed with stolen credentials. Following an existing graph-infection based approach leveraging the constrained time when stolen credentials are useful, we design a blockcha...

In this paper, we propose a privacy-preserving i-voting system based on the public Stellar Blockchain network. We argue that the proposed system satisfies all requirements stated for a robust i-voting system including transparency, verifiability, and voter anonymity. The practical architecture of the system abstracts a voter from blockchain technol...

Information-centric networks––that are candidates for the title of the network of the future––struggle with a new vector of attacks. One of them is content poisoning, especially the stronger form––Fake Data CPA. ICN networks are especially prone to those types of attacks due to a lack of removal functionality. Currently, known authentication method...

ABSTRACT The primary goal of our engineering project was the construction of a hardware wallet for the Bitcoin cryptocurrency, which utilises a modular architecture to secure the wallet’s secret. None of the solutions currently available on the market provide such functionality. The project comprises of both the software and hardware aspects becaus...
