The image is significantly used in applications such as medical area, research area, image conferencing, a military image system, online transactions, digital signatures, passwords etc. But not everyone who uses this network is going to play by the rules or have the best interest at heart. Just as we have physical security like locks, fences and police officers to minimize crime in the real world. We need some security to minimize crime and harm in the virtual world. Three important factors form the security objectives of the digital content: they are Availability, Confidentiality, and Integrity. Watermarking techniques along with some Cryptography are used to protect the confidentiality of data. Watermarking is basically a process of injecting data into an image in such a way that it can depict the authenticity of those possessing it. The digital information hidden inside an image is imperceptible to the user but can be easily detected by a computer or various digital devices. Watermarking Technique has proved to be a powerful technique for image security and a lot of research has been made over the years to how to embed the watermarks and recover the watermarks effectively. These types of technique where watermark can be fully extracted from the image and along with the restoration of the cover are popularly known as Reversible Watermarking techniques. These techniques have significantly gained importance due to this excellent recovering property making them suitable for content authentication based applications. However, they are not able to identify any modifications or changes done in watermark making it susceptible to tamper location-based attacks. Due to the rapid development of watermarking techniques, a concluding review of recent research in this field is highly desirable. However, the major focus of this paper is on tamper localization based reversible watermarking techniques.

Autism spectrum disorder (ASD) cases have increased rapidly in recent decades, which is associated with various genetic abnormalities. To provide a better understanding of the genetic factors in ASD, we assessed the global scientific output of the related studies. A total of 2944 studies published between 1997 and 2018 were included by systematic retrieval from the Web of Science (WoS) database, whose scientific landscapes were drawn and the tendencies and research frontiers were explored through bibliometric methods. The United States has been acting as a leading explorer of the field worldwide in recent years. The rapid development of high-throughput technologies and bioinformatics transferred the research method from the traditional classic method to a big data-based pipeline. As a consequence, the focused research area and tendency were also changed, as the contribution of de novo mutations in ASD has been a research hotspot in the past several years and probably will remain one into the near future, which is consistent with the current opinions of the major etiology of ASD. Therefore, more attention and financial support should be paid to the deciphering of the de novo mutations in ASD. Meanwhile, the effective cooperation of multi-research centers and scientists in different fields should be advocated in the next step of scientific research undertaken.

As current society’s reflection on the rapid development of motorization and increasing emphasis on the ecological environment, the study of walkable cities has become one of the key points of urban sustainable design. Creating a walkable city is an effective way to build a low-carbon and healthy city. With the development of cities, walkability concepts and theories are constantly being given new life, and research methods and design strategies continue to be updated. A city’s walkability and walkability index have become current research hotspots. Based on prior research on walkability and related urban policies, this study selects Coomera Town on the Gold Coast of Queensland, Australia, as the research area because of Coomera Town policy regulations and environmental requirements. This study utilizes traditional qualitative and quantitative research methods, machine mining technology, and the deep learning big data analysis technology to conduct thematic design research in a real place. Its combines walkability evaluation with walkability design to construct a walkable city in a targeted manner. This provides a reference for related city design in the future.

The rapid development of intelligent networked vehicles (ICVs) has brought many positive effects. Unfortunately, connecting to the outside exposes ICVs to security threats. Using secure protocols is an important approach to protect ICVs from hacker attacks and has become a hot research area for vehicle security. However, most of the previous studies were carried out on V2X networks, while those on in-vehicle networks (IVNs) did not involve Ethernet. To this end, oriented to the new IVNs based on Ethernet, we designed an efficient secure scheme, including an authentication scheme using the Scalable Service-Oriented Middleware over IP (SOME/IP) protocol and a secure communication scheme modifying the payload field of the original SOME/IP data frame. The security analysis shows that the designed authentication scheme can provide mutual identity authentication for communicating parties and ensure the confidentiality of the issued temporary session key; the designed authentication and secure communication scheme can resist the common malicious attacks conjointly. The performance experiments based on embedded devices show that the additional overhead introduced by the secure scheme is very limited. The secure scheme proposed in this article can promote the popularization of the SOME/IP protocol in IVNs and contribute to the secure communication of IVNs.

Introduction. The use of technical means for copyright protection is regulated not only in Russian legislation, but also in foreign and international law. It means that the international concept of intellectual property protection could be perceived differently by foreign jurisdictions, which, in turn, is of special scientific interest. The foundations of legal regulation are laid down in international treaties, which in the intellectual property law are tools that contain substantive rules of law. The provisions of such treaties are implemented in the national (supranational) legislation, and, therefore, become part of them and subject to additions.. The article is devoted to the study of international legal regulation of the use of technical means for copyright protection.Materials and methods. The methodological basis of the research consists of the following general scientific and special methods of cognition of legal phenomena and processes: dialectical, formal-legal, comparative-legal, formal-logical, structural-functional.Results of the study. The authors found that attempts to protect copyright using technology available at every stage of history were undertaken by individual countries, beginning from the second half of the 19th century. However technical means of protection received legal regulation at the international level relatively recently, the prerequisite for that was the rapid development of digital information technologies. Analysis of international legal norms in the field of legal regulation of technical means of copyright protection has shown that at present international legal regulation is of a general nature, providing each of the states at the national level with ample opportunities for legal concretization of gen-eral norms. However, recently the Internet treaties of WIPO recognized for the first time not only the advisability of the use of technical means of protection, but also the obligation prohibiting circumvention of such protection technologies, and therefore national legislations should contain provisions regulating the circumvention of such protection technologies.Discussion and Conclusions. The introduction of international law with regard to the use of the protection technologies, despite their general and abstract nature, has given a serious impetus to the establishment of legal regulation of this institution at the national level. At the same time, the rules governing the use of the protection technologies in the near future will require greater unification and concretization due to the rapid development of digital information technologies, blurring the borders between states in terms of disseminating the results of intellectual activity, and also in order to avoid a multiplicity of interpretation of law and to ensure effective legal regulation and protection of copyright.

Content Based Filtering

Recent years have witnessed the fast development of the emerging topic of Graph Learning based Recommender Systems (GLRS). GLRS mainly employ advanced graph learning approaches to model users’ preferences and intentions as well as items’ characteristics and popularity for Recommender Systems (RS). Differently from other approaches, including content based filtering and collaborative filtering, GLRS are built on graphs where the important objects, e.g., users, items, and attributes, are either explicitly or implicitly connected. With the rapid development of graph learning techniques, exploring and exploiting homogeneous or heterogeneous relations in graphs is a promising direction for building more effective RS. In this paper, we provide a systematic review of GLRS, by discussing how they extract knowledge from graphs to improve the accuracy, reliability and explainability of the recommendations. First, we characterize and formalize GLRS, and then summarize and categorize the key challenges and main progress in this novel research area.

The Future

As a result of the rapid development of intercultural communication and global transformations taking place in the world in the 90s of the XX century, it became necessary to create a new personality with a new set of qualities and competencies that are urgently needed for the rational functioning in a multicultural world. For the successful performance of professional duties is not enough to be a specialist who knows job, today. Modern Ukrainian society needs educated professionals who can think critically and make decisions independently in a situation that requires a choice, that is, to be dynamic, mobile, creative. That is, the main feature of professional activity is its development, which requires constant updating and improvement of skills. Each specialist should acquire new knowledge and improve their skills, and, consequently, improve their professional qualities. According to research, professionals who are not engaged in improving professional competence, there comes a time in life when they have internal dissatisfaction with their activities and they need to improve professional skills, or even change their professional orientation. Given the large variety of information technologies at all educational levels, it is not difficult to improve your professional level, and mobile learning is a way to solve a number of educational problems today. In this regard, the relevance of communicative education of future police officers is increasing. After all, the need to train a competent police officer capable of effective professional activity in a multi-ethnic environment is a priority in the training of future police officers in the parameters of European standards. The socio-cultural aspect in the professional training of future police officers is not only the formation of communicative competence, but also the space of interpersonal relations, in which a holistic culture of the individual is formed. The article presents an analysis of the diagnostic results of the formation of communicative competence of the future police officer. The results demonstrate the levels of formation of communicative competence of future police officers in cognitive, emotional and behavioural components.

With the rapid advancement of music compression and storage technologies, digital music can be easily created, shared and distributed, not only in computers, but also in numerous portable digital devices. Music often constitutes a key component in many multimedia databases, and as they grow in size and complexity, their meaningful search and retrieval become important and necessary. Music Information Retrieval (MIR) is a relatively young and challenging research area started since the late 1990s. Although some form of music retrieval is available on the Internet, these tend to be inflexible and have significant limitations. Currently, most of these music retrieval systems only rely on low-level music information contents (e.g., metadata, album title, lyrics, etc.), and in this chapter, the authors present an adaptive indexing approach to search and discover music information. Experimental results show that through such an indexing architecture, high-level music semantics may be incorporated into search strategies.

In today’s world, security is the most prominent aspect which has been given higher priority. Despite the rapid growth and usage of digital devices, lucrative measurement of crimes in under-developing countries is still challenging. In this work, unstructural crime data (900 records) from the news archives of the previous eight years were extracted to predict the behavior of criminals’ networks and transform it into useful information using natural language processing (NLP). To estimate the next move of criminals in Pakistan, we performed hotspot-based spatial analysis. Later, this information is fed to two different classifiers for possible identification and prediction. We achieved the maximum accuracy of 92% using K-Nearest Neighbor (KNN) and 62% using the Random Forest algorithm. In terms of crimes, the results showed that the most prevalent crime events are robberies. Thus, the usage of digital information archives, spatial analysis, and machine learning techniques can open new ways of handling a peaceful and sustainable society in eradicating crimes for countries having paucity of financial resources.
