Research on digital image watermark encryption based on hyperchaos

The digital watermarking technique embeds meaningful information into one or more watermark images hidden in one image, in which it is known as a secret carrier. It is difficult for a hacker to extract or remove any hidden watermark from an image, and especially to crack so called digital watermark. The combination of digital watermarking technique and traditional image encryption technique is able to greatly improve anti-hacking capability, which suggests it is a good method for keeping the integrity of the original image. The research works contained in this thesis include: (1)A literature review the hyperchaotic watermarking technique is relatively more advantageous, and becomes the main subject in this programme. (2)The theoretical foundation of watermarking technologies, including the human visual system (HVS), the colour space transform, discrete wavelet transform (DWT), the main watermark embedding algorithms, and the mainstream methods for improving watermark robustness and for evaluating watermark embedding performance. (3) The devised hyperchaotic scrambling technique it has been applied to colour image watermark that helps to improve the image encryption and anti-cracking capabilities. The experiments in this research prove the robustness and some other advantages of the invented technique. This thesis focuses on combining the chaotic scrambling and wavelet watermark embedding to achieve a hyperchaotic digital watermark to encrypt digital products, with the human visual system (HVS) and other factors taken into account. This research is of significant importance and has industrial application value

Flexi-WVSNP-DASH: A Wireless Video Sensor Network Platform for the Internet of Things

abstract: Video capture, storage, and distribution in wireless video sensor networks (WVSNs) critically depends on the resources of the nodes forming the sensor networks. In the era of big data, Internet of Things (IoT), and distributed demand and solutions, there is a need for multi-dimensional data to be part of the Sensor Network data that is easily accessible and consumable by humanity as well as machinery. Images and video are expected to become as ubiquitous as is the scalar data in traditional sensor networks. The inception of video-streaming over the Internet, heralded a relentless research for effective ways of distributing video in a scalable and cost effective way. There has been novel implementation attempts across several network layers. Due to the inherent complications of backward compatibility and need for standardization across network layers, there has been a refocused attention to address most of the video distribution over the application layer. As a result, a few video streaming solutions over the Hypertext Transfer Protocol (HTTP) have been proposed. Most notable are Apple’s HTTP Live Streaming (HLS) and the Motion Picture Experts Groups Dynamic Adaptive Streaming over HTTP (MPEG-DASH). These frameworks, do not address the typical and future WVSN use cases. A highly flexible Wireless Video Sensor Network Platform and compatible DASH (WVSNP-DASH) are introduced. The platform's goal is to usher video as a data element that can be integrated into traditional and non-Internet networks. A low cost, scalable node is built from the ground up to be fully compatible with the Internet of Things Machine to Machine (M2M) concept, as well as the ability to be easily re-targeted to new applications in a short time. Flexi-WVSNP design includes a multi-radio node, a middle-ware for sensor operation and communication, a cross platform client facing data retriever/player framework, scalable security as well as a cohesive but decoupled hardware and software design.Dissertation/ThesisDoctoral Dissertation Electrical Engineering 201

Works for Works, Book 1

Works for Works, Book 1: Useless Beauty tackles “legacy” issues of intellectual property rights (IPR) in artistic production and academic scholarship and proposes a category or class of works that has no relation to IPR nor to proprietary regimes of copyright and academic privilege. Keeney’s book is a structuralist argument for establishing new forms of artistic scholarship that operate in direct opposition to established norms in both the art world and neoliberal academia, and is also rigorously contextualized within past and present-day arguments for and against patrimonial and paternalistic, avant-garde and normative, forms of censure and conformity across cultural production. Works for Works, Book 1: Useless Beauty privileges an iterative, generative, and aleatory methodology for artistic scholarship, with transmedia proposed as a “tutelary form” of editioning works against the dictates of the art-academic complex. This focus on generativity also invokes the dialectical operations historically associated with past avant-gardes as they have negotiated an elective nihilism as an avenue for exiting established and authorized forms of conceptual and intellectual inquiry in the Arts and Humanities

Legal Anarchism: Does Existence Need to Be Regulated by the State

This thesis asks does existence need to be regulated by the State? The answer relies on legal anarchism, an interdisciplinary, particularly criminal law and philosophy, and unconventional research project based on multiple methodologies with a specific language. It critically analyzes and consequently rejects State law because of its unjustified and unnecessary nature founded on unlimited violence and white-collar crime (Chapters 1-4), on the one hand, and suggests some alternatives to the Governmental legal system founded on agreement and peace (Chapter 5), on the other hand. It furthermore takes into account the elements of time and space, which means the ecological, local, national, regional, and international aspects of the legal system, in its analysis, critiques, and models

"My life transparently revealed" : interpreting Mahler's worldview through an analysis of his middle-period symphonies

Many of the comments made by Gustav Mahler concerning the relationship between his life experiences and musical compositions have compelled scholars to interpret his work through the lens of his worldview. From the known facts of his reading habits, social circle, and references to philosophy, one can establish a general picture of Mahler’s interests, beliefs, and values. But to go beyond these generalities requires a more in-depth understanding of worldview and how it manifests in artistic expression. This project attempts to answer this need by investigating the concept of worldview through an analysis of the works of Mahler’s middle-period: the Fifth, Sixth, and Seventh Symphonies. Chapter One pursues a deeper understanding of what is meant by the term “worldview” and its relationship to art. This chapter lays a theoretical foundation that combines a historically informed definition of worldview with the philosophy of Paul Ricoeur to create a methodology for the case studies that will follow. Worldviews, while variable in content, contain a tripartite structure consisting of narratives, symbols, and values. The case studies that follow examine the works of the middle period under the rubric of these elements. Chapter Two analyzes the Fifth Symphony’s narrative structure, applying the insights of that investigation to Ricoeur’s notion of “narrative identity.” Chapter Three focuses on a specific musical symbol used in the Sixth Symphony—commonly known as the Ewigkeit motive—and examines how Mahler’s use of this symbol in other works illuminates its philosophical meaning and its expressive role in the Sixth. The final case study, Chapter Four, theorizes that Mahler’s compositional process serves as the outward expression of his inner beliefs. It considers the development of the Seventh Symphony as evidence of how value-structures manifest themselves as modes of being and doing. The final study concludes by drawing together the insights of the three analyses to offer an interpretation of Mahler’s worldview as expressed in the symphonic trilogy of the middle period.Musi
