In this paper we propose a system that is based on distributed file storage and on the blockchain technology, as implemented by the PrivateSky platform. It offers a number of improvements to existing cloud storage and communication solutions, and is designed to be suitable in a large variety of contexts. Data that is exchanged between users is encr...

InterPlanetary File System (IPFS) with its specific features is a novelty to the data distribution area. In this article we are analyzing this filesystem/protocol and we will conduct a parallel study based on the comparison to other distributed file systems (DFSs) and to HTTP (Hypertext Transfer Protocol). IPFS provides efficient data storage and d...

With the everlasting development of technology and society, data privacy has proven to grow into a pressing issue. The bureaucratic state system seems to expand the number of personal documents required for any kind of request. Therefore, it becomes obvious that the number of people having access to information that should be private is on the rise...

Blockchain has emerged as a trusted and secure distributed ledger for transactions while also being decentralised, distributed and its legitimacy not guaranteed by a trusted authority. Since the appearance of Bitcoin, Blockchain has known many implementations based on P2P architectures. This paper presents how the blockchain and smart contracts tec...

In this paper we propose a solution for reducing the time needed to make changes in an application in order to support a new version of a software dependency (e.g., library, interpreter). When such an update is available, we do not know if it comes with some changes that can break the execution of the application. This issue is very serious in the...

Programming for cloud systems looks deceptively similar with programming web and enterprise applications except that it is harder. The challenges that a few years ago were reserved only for distributed systems specialists from academia or from big internet companies are now coming to masses. The well known methods of dealing with concurrency and sc...

The paper presents roGSEM (Romanian Governmental Semantic Portal), a platform able to provide access to legal open governmental data: normative documents published by the Romanian state. The proposed solution is based on Semantic Web technologies and uses the information according to the Linked Data initiative. Also, roGSEM semantic data repository...

The paper presents a unified solution for detecting, processing, validating, and exporting various data expressed by different existing semantic markups (microformats, HTML5 microdata, and RDFa) embedded into Web pages. The developed tool is available as a browser extension and a bookmarklet, providing a modular architecture.

In this paper we propose SINUX, a Linux distribution especially created for those who want to learn and use the currently existing Semantic Web technologies. It has integrated many important instruments and references to online informations, making it easy for the users to have a proper development environment without any hassle.
