Opis:
Data security in cloud services is achieved by imposing a broad range of privacy settings and restrictions. However, the different security techniques used fail to eliminate the hazard of serious data leakage, information loss and other vulnerabilities. Therefore, better security policy requirements are necessary to ensure acceptable data protection levels in the cloud. The two procedures presented in this paper are intended to build a new cloud data security method. Here, sensitive data stored in big datasets is protected from abuse via the data sanitization procedure relying on an improved apriori approach to clean the data. The main objective in this case is to generate a key using an optimization technique known as Corona-integrated Archimedes Optimization with Tent Map Estimation (CIAO-TME). Such a technique deals with both restoration and sanitization of data. The problem of optimizing the data preservation ratio (IPR), the hiding ratio (HR), and the degree of modification (DOM) is formulated and researched as well.

Opis:
The present day Internet provides a wide range of services users can benefit from. Some of the services require gathering, processing and presenting data that come from many users in order to deliver additional information. The suitable example can be social networking service. The more valuable data it stores and processes, the more profitable it can become. Users’ personal data can constitute significant value. One of the issues of social networking is storing and processing data by only one entity. Users cannot choose the most suitable security policy because there is only one provided for certain social network. Being part of it, means accepting the risk of unauthorized data distribution and data leakage because of application vulnerabilities. This paper presents new architecture of social network, which provides mechanisms for dividing data between more than one entity and combining independent data repositories in order to deliver one social network with clearly defined interfaces used to connect new data sources.

Opis:
In the digitalized era of the information technology the expansion of the data usage is very high accounting for about enormous data transaction in day to day life. Data from different sources like sensors, mobile phones, satellite, social media and networks, logical transaction and ventures, etc add an gigantic pile to the existing stack of data. One of the best way to handle this exponential data production is the Hadoop network. Thus in the current scenario big industries and organizations rely on the Hadoop network for the production of their essential data. Focusing on the data generation and organization, data security one of the most primary important consideration was left unnoticed making data vulnerable to cyber attacks and hacking. Hence this article proposes an effective mixed algorithm concept with the Salsa20 and AES algorithm to enhance the security of the transaction against unauthorised access and validates the quick data transaction with minimal encryption and decryption time. High throughput obtained in this hybrid framework demonstrates the effectiveness of the proposed algorithmic structure over the existing systems

Opis:
The popularity of smart devices that collect and share data on user behaviour grows every year, and the number of such devices in households is forecast to rise steadily. Therefore, the purpose of this paper is to present the attitudes of young consumers regarding the security of their data collected by smart devices, interconnected via the existing Internet infrastructure or other network technologies within the Internet of Things (IoT) systems. The paper was written based on both secondary and primary sources of information. Secondary sources were used to define the discussed issues related to the Internet of Things and the security of data collected by smart devices. Primary sources, on the other hand, offered direct evidence of the attitudes of young consumers on the security of such data. Direct research was carried out using an online survey carried out in 2021 on a sample of 588 consumers aged 18–34 living in Poland. The results show that more than half of the respondents pay great attention to where the data collected by the devices used in their households is kept and whether such data is safe. In spite of such declarations, more than half of those surveyed have no knowledge about the level of the security of such data. The respondents agreed with the statement that consumers accepted the uncertainty related to the loss of control over their personal data collected by smart devices more quickly than the risk involved in becoming disconnected from them.

Opis:
W pracy zaproponowano mechanizm zapewniania bezpieczeństwa danych poddanych zagrożeniom wynikającym z awarii systemu komputerowego lub sprzętu komputerowego. Przedstawione w pracy rozwiązanie polega na uruchomieniu klastra wysokiej dostępności dla bazy danych środków trwałych Instytutu Przeróbki Plastycznej i Inżynierii Bezpieczeństwa opartego o narzędzie do replikacji danych oraz narzędzie do kontroli dostępności poszczególnych węzłów klastra. W pracy zastosowano DRBD - narzędzie do replikacji urządzeń blokowych, które działa jako moduł jądra służący do mirrorowania systemów plików przez sieć [6]. DRBD umożliwia ochronę danych komputerowych poprzez zapis lustrzany w pamięciach dyskowych. Polega to na dublowaniu zapisu danych, w wyniku czego dwa urządzenia przechowują taką samą informację. Jako narzędzia kontroli dostępności poszczególnych węzłów klastra w pracy użyto z kolei systemu Heartbeat, który sprawdza operacje wejścia-wyjścia w celu zapewnienia spójności danych, a następnie przenosi zasoby na alternatywny węzeł [5].
In the work the security system of data subjected to risks arising from the failure of a computer system or computer equipment was presented. The analyzed solution is based on creation of high-availability cluster for database of fixed assets in Institute of Metal Forming and Safety Engineering. The proposed security system is based on DRBD software, replicated storage solution mirroring the content of hard disks, partitions, logical volumes etc. between hosts connected via Ethernet [6]. DRBD enables replication of selected services like MySQL server or http server to ensure mirroring of data managed by these servers. The Heartbeat service was used in the analyzed solution as a tool to control availability of the several nodes of the cluster to check the input– output operations and decides when to transfer the selected resources to satellite node [5].

Opis:
The goal of this exploratory case study is to identify different facets of news reporting on surveillance, privacy and data security, and more specifically, how risks in this context are portrayed. The theoretical foundation consists of two elements: 1) the concept of mediatized risk culture, and 2) the discursive arena model of risk communication, which provides the normative background for assessing news reporting. A text-mining approach (topic modeling) is applied to analyze relevant coverage of the German quality newspaper Süddeutsche Zeitung. The study yields a total of seven topics which belong to three categories: violation of privacy norms, power and law enforcement, and datafication. The results show that despite the de-mystification of digital technology after the Snowden leaks, coverage has recently become more affirmative and less focused on risk. We conclude that this may indicate a normalization of mass surveillance and data harvesting even in Germany, a society which traditionally values privacy. In order to add more context to our findings, however, further qualitative analyses were needed. The paper serves as a starting point for further research on media reporting of surveillance, privacy and data security.

Opis:
Rapid development of online medical technologies raises questions about the security of the patient’s medical data.When patient records are encrypted and labeled with a watermark, they may be exchanged securely online. In order to avoid geometrical attacks aiming to steal the information, image quality must be maintained and patient data must be appropriately extracted from the encoded image. To ensure that watermarked images are more resistant to attacks (e.g. additive noise or geometric attacks), different watermarking methods have been invented in the past. Additive noise causes visual distortion and render the potentially harmful diseases more difficult to diagnose and analyze. Consequently, denoising is an important pre-processing method for obtaining superior outcomes in terms of clarity and noise reduction and allows to improve the quality of damaged medical images. Therefore, various publications have been studied to understand the denoising methods used to improve image quality. The findings indicate that deep learning and neural networks have recently contributed considerably to the advancement of image processing techniques. Consequently, a system has been created that makes use of machine learning to enhance the quality of damaged images and to facilitate the process of identifying specific diseases. Images, damaged in the course of an assault, are denoised using the suggested technique relying on a symmetric dilated convolution neural network. This improves the system’s resilience and establishes a secure environment for the exchange of data while maintaining secrecy.
