In the context of the rapid development of the information and communication economy, the management system of social and economic agents in Ukraine is forced to respond promptly to constant changes in the digital society. They have to process large amounts of multiparameter data daily for efficient operation and management. To ensure these processes are information technologies that support from Big Data and the Intellectual technology of analytical process. We proposed based on this technology decide decision on the financial equilibrium of a commercial enterprise.

W warunkach szybkiego rozwoju gospodarki informacyjnej i komunikacyjnej system zarządzania agentami społecznymi i gospodarczymi na Ukrainie zmuszony jest do natychmiastowego reagowania na ciągłe zmiany w społeczeństwie cyfrowym. Mają codziennie przetwarzać duże ilości danych multiparametrycznych w celu zapewnienia skutecznego działania i zarządzania. Procesy te mogą być dostarczane przez technologie informatyczne, które obsługują przetwarzanie dużych zestawów danych (Big Data) i ich inteligentnych technologii przetwarzania analitycznego. Zaproponowano do podjęcia decyzji o równowadze finansowej w przedsiębiorstwie komercyjnym na podstawie tej technologii.

This paper presents secure data storage model based on cloud storage services, which improves basic security aspects such as confidentiality, integrity and availability. Extended model introduces several improvements, where the most important are RAID techniques, “off-line” mode and node distribution mechanism. The document briefly describes additional network node called “proxy node” and contains the system’s security considerations.

Niniejszy dokument prezentuje model bezpiecznego składowania danych oparty o magazyny chmurowe, dzięki któremu możliwe jest polepszenie podstawowych aspektów bezpieczeństwa takich jak poufność, integralność oraz dostępność. Rozszerzony model wprowadza wiele usprawnień w tym technikę RAID, tryb „off-line” i mechanizm rozproszenia (redundancji) węzła. Ponadto zdefiniowano dodatkowy węzeł sieci nazwany „pośredniczącym” oraz zawarto rozważania w temacie bezpieczeństwa systemu.

Cloud storage is a significant service provided by the cloud that enables users to store their immense data into the cloud. As the advent of the big data era, cloud storage services are becoming increasingly popular. For security reasons, data owners would like to check the integrity of their data after storing it in the cloud. To do this, they usually make use of the public cloud data integrity checking schemes. This paper focuses on user anonymity in such schemes so that no third party could infer the identity information of any data owner from checking procedures. The problem is obviously inevitable in reality, however the current solutions are relatively involved as they heavily use public key certificates and/or incur huge communication overhead. In this paper we introduce the concept of attribute-based cloud data integrity checking to achieve user anonymity lightly and present security models for such systems. We also provide a practical construction and prove its security in the random oracle model. Finally, we show how to extend our construction to protect data privacy against any third party.

In this paper, description of a concept of cloud storage is offered. Cloud data storage is a model of an online storage where the data is being stored in multiple, divided between network servers that are provided for clients’ usage, mostly by a third-party company. The majority of the cloud storages (as opposed to file-exchangers) are offering almost boundless set of functions for free, by only limiting the size of the available storage (mostly a couple of gigabytes). Integrated data mining is being used for extracting potentially useful information from unprocessed data. The methods of data analysis are quite important with cloud computing. The implementation of the methods of integrated data mining inside the cloud will let the users receive the helpful information from non-structured or half-constructed web data sources. The main purpose of this work is to organize huge diverse data coming from different sources into clusters, depending on the type of data.

In the paper analysis of available, free Cloud Storage services for company/enterprise applications is presented. The choice of the most appropriate cloud service will be associated with such features as its compatibility in relation to the terms of use, data security, performance and stability. Performed analysis focuses on solutions which the license does not prohibit the use of their free version of the service for commercial purposes, in the company. An important factor, partly influencing for the choice, will also be intuitiveness, additional functionality and ease of use offered by client applications.

In this paper, description of a concept of cloud Storage age is offered. One of the most practical methods of storing required information to cloud storage is also considered. Method of creating screenshots is proposed. Theoretical research is carried out and there are justified advantages and disadvantages of different methods of storing information in social networks. The best technique of creating screenshots has been practically implemented. Problems that might come up while working with approach given in this article and its solutions are stipulated. There is analyzed a necessity of setting a zoom parameter which is to transfer after transmitting size value of the picture in social networks. In the article the parameter that specifies the width of the final image and clearly affects the quality of the image is also considered. There is analyzed the effectiveness of creating an information system that saves time for such information processes as tracking the photo and its comments. In the paper the task of changing bets, which are not immediately fixed in social networks is optimized. Also there is implemented in practice a scalability problem of information processes in social networks. In the article a separation of the script is also put into practice. One part of which directly performs the request of image and downloads it to cloud storage. With help of another part the information process is transmitted on the photo where the user identifies.

The innovation of application of cloud managers is described in the article. The authors emphasize that the innovative direction of development of information activities is the integration of Web platforms (social networks and cloud storages) for creating a unified communication space and storage for large amount of information. Tool that provides this development are cloud managers. For library institutions using such technologies will create the favorable and flexible serviceoriented system for providing users with information resources. For determination of free cloud managers and selected among them a benchmark, the methods of benchmarking and expert evaluation were used in the research. The algorithm for operation with every service is given. The following technological capabilities: “integration with cloud storage”, “cloud disk space manager”, “multimedia playback,” “presence of workspace” for collaboration were taken into account. The result of the study is to determine the cloud manager that can serve as a benchmark for providing free cloud services with a wide range of technological capabilities.
