Copyright protection of scalar and multimedia sensor network data using digital watermarking

This thesis records the research on watermarking techniques to address the issue of copyright protection of the scalar data in WSNs and image data in WMSNs, in order to ensure that the proprietary information remains safe between the sensor nodes in both. The first objective is to develop LKR watermarking technique for the copyright protection of scalar data in WSNs. The second objective is to develop GPKR watermarking technique for copyright protection of image data in WMSN

For most scientific and engineering problems simulated on computers the solving of problems of the computational mathematics with approximately given initial data constitutes an intermediate or a final stage. Basic problems of the computational mathematics include the investigating and solving of linear algebraic systems, evaluating of eigenvalues and eigenvectors of matrices, the solving of systems of non-linear equations, numerical integration of initial- value problems for systems of ordinary differential equations.Для більшості наукових та інженерних задач моделювання на ЕОМ рішення задач обчислювальної математики з наближено заданими вихідними даними складає проміжний або остаточний етап.

Symmetry-Adapted Machine Learning for Information Security

Symmetry-adapted machine learning has shown encouraging ability to mitigate the security risks in information and communication technology (ICT) systems. It is a subset of artificial intelligence (AI) that relies on the principles of processing future events by learning past events or historical data. The autonomous nature of symmetry-adapted machine learning supports effective data processing and analysis for security detection in ICT systems without the interference of human authorities. Many industries are developing machine-learning-adapted solutions to support security for smart hardware, distributed computing, and the cloud. In our Special Issue book, we focus on the deployment of symmetry-adapted machine learning for information security in various application areas. This security approach can support effective methods to handle the dynamic nature of security attacks by extraction and analysis of data to identify hidden patterns of data. The main topics of this Issue include malware classification, an intrusion detection system, image watermarking, color image watermarking, battlefield target aggregation behavior recognition model, IP camera, Internet of Things (IoT) security, service function chain, indoor positioning system, and crypto-analysis

Blockchain Copyright Exchange – A Prototype

The copyright market for creative works such as music and movies traditionally involves a complex web of licensing transactions and exorbitant transaction costs. Out of every dollar that consumers pay, an artist who writes, performs, and produces her own work may receive less than fifteen cents while the rest are diverted to cover the costs of financing new production, marketing new works, and distributing royalties. Although artists are typically scheduled to receive royalties on a quarterly basis, a payment may lag as far as two years after users paid. Furthermore, if a collecting society is unable to identify the rightful owner for a royalty payment, it routinely allocates the royalty among its existing members. This Article proposes a blockchain copyright exchange (“BCE”) that dramatically improves efficiency and accuracy in copyright transactions by hardcoding thousands of copyright rules and license terms in blockchain-based smart contracts. First, BCE allows artists to earn a royalty per stream potentially sixteen times larger than Spotify offers and eighty times larger than YouTube offers. Artists receive payments at a speed millions of times faster, in a matter of seconds instead of months, with zero administrative charges and zero dollars falling through the cracks. Second, BCE allows artists to launch crowdfunding campaigns inviting fans to securely finance creative works in return for a share of copyright ownership in the form of a non-fungible token (“NFT”) or a fungible token (“FT”). It significantly diversifies the investment risks for artists and labels alike. Third, BCE cultivates a healthy ecosystem among artists and users by mobilizing users to mine BCE tokens through distribution and promotion of licensed works. These powerful incentives, together with BCE’s innovative enforcement mechanisms, may effectively eliminate the breeding ground for copyright piracy

Dynamical Systems

Complex systems are pervasive in many areas of science integrated in our daily lives. Examples include financial markets, highway transportation networks, telecommunication networks, world and country economies, social networks, immunological systems, living organisms, computational systems and electrical and mechanical structures. Complex systems are often composed of a large number of interconnected and interacting entities, exhibiting much richer global scale dynamics than the properties and behavior of individual entities. Complex systems are studied in many areas of natural sciences, social sciences, engineering and mathematical sciences. This special issue therefore intends to contribute towards the dissemination of the multifaceted concepts in accepted use by the scientific community. We hope readers enjoy this pertinent selection of papers which represents relevant examples of the state of the art in present day research. [...
