Dual-emissive BT-CP-TD covalent organic polymers for detecting furacillin, white light emission and information encryption

Recently, luminescent covalent organic polymers (LCOPs) are garnering more and more attention owing to their excellent emissive properties. However, the precise control of LCOPs’ luminescence behaviors remains a formidable challenge. Here, a dual-emissive CP-(BTxTD100-x) COP which was composited of CP, BT and TD (x is the added molar ratio of BT to total feed aldehyde) were synthesized by Knoevenagel condensation reaction between 1,3,5-tri(4-cyano-methylbenzene) benzene (CP) and 2,7-dibenzaldehyde-benthiadiazole (BT)/1,4-bis(4-aldehyde phenyl)benzene (TD). The luminescent behaviors of CP-(BTxTD100-x) COP could be precisely tuned by the ratio of CP, BT and TD as well as excitation wavelength. The CP-(BT33TD67) COP emitted white light (0.3012, 0.3207) when excited at 310 nm. A ratiometric fluorescence sensor was developed for detecting furacillin using CP-(BT33TD67) COP, showing a detection limit of 8.23 ng mL−1. Based on the excitation-depending behaviors of CP-(BT33TD67) COP, combined with CP-(BT100TD0) COP, a kind of security and information encryption image in the form of a quick response was designed. The discoveries provide a new idea for the design of dual-emission LCOPs by regulating the ratio of monomers and excitation wavelengths. The findings also extend the potential applications of dual-emission LCOPs.

A lattice-based public key encryption scheme with delegated equality test

When data security is facing growing threats, ordinary encryption techniques cannot meet the needs of comparing, sharing, and classifying data hidden in ciphertexts. At the same time, the advent of the quantum computing era has brought unprecedented challenges to traditional cryptography. Fortunately, a lattice-based PKEET scheme can solve the above problems. In this paper, we design a lattice-based PKE-DET scheme that can support the delegated tester function with satisfying anti-quantum computing security and resisting OMRA attacks. To the best of our knowledge, this is the first PKE-DET scheme that has both kinds of security at the same time. Under the standard model, we prove the security of the scheme based on the LWE hardness assumption. Compared with existing schemes, our scheme has many advantages, such as high security, delegated tester authorization, and small storage space.

CRIME VICTIMIZATION OF NEUST CRIMINOLOGY STUDENTS LIVING IN BOARDING HOUSES AT SUMACAB ESTE, CABANATUAN CITY

Being a victim of crime is a phenomenon which may not be common to everyone, but is of great probability of happening anytime in our lives. This is because no one can actually predict and control the actions of other people especially those who intend to commit them. It is therefore important, that for us not be victimized, we have to create a certain kind of security within us, that is, we police ourselves. It is not enough that we depend on our police force for our security, but more importantly, we have to be responsible enough to keep ourselves secure and not put ourselves in a compromising situation that could lead to victimization. In the Philippines, the Philippine National Police (PNP) (2006) stated that they are committed in ensuring public safety and reducing the fear and the incidence of crime in the community. However, they acknowledge that there are many things that each and every community member can do to reduce their chances of becoming a victim or prevent the incidence of crime from happening.

Fusion of Thermal and Depth Image to Improve Human Segmentation for a Mobile Robot

In machine vision, surveillance systems are a kind of security that concentrates on the safety of the human and property. One of the main tasks of a surveillance system is the detection of humans. This paper presents a system of human detection and the development of a technique of human segmentation using a combination of information thermal and depth in a real indoor setting from a mobile robot. A novel fusion of thermal-depth information (FTDI) is introduced to enhance the efficiency of the segmentation process and expedite processing. In experimental studies, evaluation of the performance for the proposed system is carried out using Ground Truth (GT), in which the proposed system yield is compared to GT. The proposed system performs well with an approximate accuracy of over 90% for all data sets as illustrated in the quantitative results and even outperformed state-of-the-art algorithms. This paper presents the novelty of the work, in which the detection method can improve the classification of persons and their occlusion. The advantages, such as being computationally inexpensive and performs well even under severe occlusion and poor illumination, show that this proposed system is robust.

Prometheus Tamed: Fire, Security, and Modernities, 1400 to 1900 by Cornel Zwierlein (review).

Reviewed by: Prometheus Tamed: Fire, Security, and Modernities, 1400 to 1900 by Cornel Zwierlein Edward Tenner (bio) Prometheus Tamed: Fire, Security, and Modernities, 1400 to 1900 By Cornel Zwierlein. Leiden: Brill, 2021. Pp. 547. To scholars and lay people alike, the Enlightenment may mean many things—rejection of revealed religion, celebration of science and reason, and advocacy of human rights. In Prometheus Tamed, Conrad Zwierlein presents a radical reinterpretation of Central European thought and institutions in the transition from the premodern era to the eighteenth and nineteenth centuries. For Zwierlein, the key to the Enlightenment as a social and political movement lies not in philosophical theory but in a new urgency in the quest for material security. A survey of keywords in German-language periodicals of the eighteenth and early nineteenth centuries reveals a striking amount of attention to fires—a retrospectively obvious point given the tolls on life and property of the conflagrations that so often ravaged early modern cities. In the two decades from 1680 to 1700, Zwierlein finds a decisive turn from an old to a new framework for dealing with fires. Well into the eighteenth century, many pious Christians continued to see fires and other natural hazards as divine punishment for the sins of the community, recalling Sodom and Gomorrah and other Biblical chastisements. The rise of deism—which denied the intervention of the Creator in nature and human affairs—was among the sins said to bring down the wrath of heaven. Governments were already abandoning this religious interpretation of urban fires in the seventeenth century and moving toward an acceptance of their inevitability. Science and experience could reduce the number of fires and contain their damage, and the destruction caused by fires could be mitigated. Gottfried Wilhelm Leibniz summarized the new attitude when he wrote in 1680 of two kinds of security: "real-assecurationen," which prevented fires, and "verbal-assecurationen," arrangements like insurance policies that provided financial relief from fire losses. Fire policy marked the arrival of a new kind of public policy in the West, a role for the [End Page 925] state and private organizations in providing security—ultimately not only against fire and flood damage but against illness. Fire insurance and firefighting technology were first steps toward a new vision of society. The author's research in both original (including archival) sources and current theoretical issues is nothing short of prodigious, especially in the theory and practice of fire insurance in the early modern German-speaking world. This book will be indispensable for scholars of early modern administrative and urban history and the history of what the author calls the "normal secure society," as well as of innovations in fire prevention and suppression technology. It even contributes to art history in its interpretation of the changing iconography of urban fires. (Some of the most striking images were created by the inventor of the modern fire hose, Jan van der Heyden, an artist-entrepreneur and veritable seventeenth-century Dutch Leonardo, who also improved firefighting pumps and devised street lighting.) There are points at which the legendary thoroughness of the Habilitationsschrift genre may intimidate nonspecialists. The early history of insurance shows that our present idea of insurance arose centuries after the first maritime contracts in Italy, for example the requirement of paying the premium in advance. The discussion of jurists' efforts to squeeze insurance contracts within the framework of Roman law is important for understanding Leibniz's innovations, but details could have been presented in a separate paper for specialists. Conversely, the author does not do justice to some of the better-known figures in the technology and discourse of fire. Benjamin Franklin receives too little attention, despite his contributions to safety technology (lightning rods, improved stoves), fire brigades, and fire insurance, which exemplified the ideas of security that Leibniz had advanced. Voltaire's poem "On the Lisbon Disaster," which mocked Leibniz's optimism in light of that city's devastation by earthquake and fire in 1755, does not appear in the bibliography of published primary sources despite its contemporary impact. The physical book is also a case study in what Thomas Hughes called the reverse salient. Digital printing on demand makes possible a...

Design of a Cloud-Blockchain-based Secure Internet of Things Architecture

The growing number of Internet of Things (IoT) objects and the operational and security challenges in IoT systems are encouraging researchers to design suitable IoT architecture. Enormous data generated in the IoT environment face several kinds of security and privacy challenges. IoT system generally suffers from several issues like data storage, safety, privacy, integrity, transparency, trust, and single point of failure. IoT environment is emerging with several solutions to resolve these problems. The main objective of this paper is to design a cloud-blockchain-based secure IoT architecture that provides advanced and efficient storage and security solutions to IoT ecosystem. Blockchain technology appears to be a decent choice to resolve such kinds of problems. Blockchain technology uses a hash-based cryptographic technique for information security and integrity. Cloud computing provides advanced storage solutions with several remote services to store, compute and analyze the data. The proposed IoT architecture is based on the integration of cloud and blockchain services, which aim to provide transparent, decentralized, and trustworthy and secure storage solutions. In addition to the standard layers (perception layer, network layer, processing layer, and application layer) the proposed IoT architecture in the present paper includes a service layer, a security layer, and a parallel management and control layer, which focus on the security and management of the entire IoT infrastructure.

Climate Security and Policy Options in Japan

Climate security has been discussed in both academia and policy documents in the West. A key point that surfaces from these discussions is that the cooperation of non-military organizations is essential for effective responses to climate change-related threats. This overlaps considerably with debates on security in Japan, where the use of force is constitutionally restricted. Therefore, it is possible to localize the concept of climate security to the genealogy of Japan’s security policy that, in the 1980s and 1990s, sought a non-traditional security strategy that did not rely solely on military power in the name of “comprehensive security,” “environmental security,” and “human security.” In Japan, the perspective of climate security is rare. However, the introduction of a unique climate security concept into security policy enables the maintenance of national security and environmental conservation. Additionally, struggling with climate change alongside neighboring countries contributes to mutual confidence building and stability in international relations in Northeast Asia. To achieve this objective, we first show that climate security includes many kinds of security concerns by surveying previous studies and comparing Western countries’ climate security policies. Second, we follow the evolution of Japan’s security policy from 1980 to 2021. Finally, we review Japanese climate security policies and propose policy options.

“The Whistleblower”

The Whistleblower Simbarashe Steyn Kundizeza (bio) It began the day I bumped into Silas Chikwama at the Eastgate shopping mall in Harare. It was raining quite heavily that January afternoon. A sizeable crowd of people had gathered under the cover of the mall's high roof. Most were milling aimlessly around, taking each other's pictures or going from one shop to another wistfully looking at expensive goods that their meagre salaries didn't allow them to buy while they waited for the rain to subside. Taking advantage of the thick crowds, a few informal and illegal currency dealers mingled unobtrusively amongst the public, recognizable only by the large wads of cash they held, muttering from time to time "maUSA, maRand"—they were exchanging United States dollars for the South African rand and vice versa. I had just come out of a bank on the ground floor when I ran into him. The last time I had seen him prior to this day was when I was in high school where he had been my teacher for three years. I felt a bit awkward seeing him now because since then I'd had a brief relationship with his niece Agatha and I wasn't sure whether he knew about this or how he felt about it if he did. He started balding and had gained weight considerably too, but on the whole he still looked the same. He spotted me first and greeted me with a very firmly grasped handshake and his characteristic rowdy, exuberant laughter. After that he launched into an endless stream of questions, which I answered as briefly as I could. I was doing quite well, thank you. Oh, my grandmother was fine. Yes, really. Yes, I'd already graduated from university. Thank you. A Bachelor of Science Honours Degree in Computer Science. Yes, that's right. A job? Well, yes. Sort of. I mean I am working, but I am still looking for something better. No, they weren't paying me much. Yes, I was sure. Chikwama shook his head in sympathy. "It's hard to find a good job these days, Frank. I feel sorry for you young people; back in our day you [End Page 239] knew you had a reasonable chance of getting a job after college. But these days …" he nodded towards a passing forex dealer "That's all you can do. Wheeling and dealing. University graduates like you are driving taxis or selling second hand clothes in flea markets. Can you imagine?'' "The situation is really bad," I agreed. "Let's hope things will get better soon," Chikwama sighed. "So how's the job? Are you still at Houghton Park High?" I asked. He looked scandalized. "No, I quit two years ago! I'm no longer in teaching. Didn't Agatha tell you?" "No, she didn't tell me," I said. Chikwama smiled at me, a lewd look on his face. So he knew about Agatha and me. "Yes, I decided to resign. Teaching is a very frustrating job nowadays, Frank. And poorly paid, too. My wife and children deserve to eat rice and chicken, not just sadza and vegetables every day, until their intestines start turning green, don't they?" They certainly did, and I said so. But what was he doing now if not teaching? He shifted his weight from one foot to the other, and looked at his watch before he said shortly, "I'm working in security these days." Security? I looked closely at him, and decided that his suit looked far too expensive for him to be a security guard. "Do you now own a security company?'' I asked. Chikwama laughed and said, "No, not that kind of security. I meant national security. For the C-Tens." C-Ten, the man on the street's nickname for the Central Intelligence Organization. If Silas Chikwama had shouted that single word, the whole Eastgate shopping mall would've frozen instantly, save perhaps for the money dealers who would've almost certainly started to flee, with visions of beefy men clad in dark suits and wielding brick-sized fists (which reputedly could knock a man senseless with just...

Quantum blockchain system

Blockchain technology represented by Bitcoin and Ethereum has been deeply developed and widely used due to its broad application prospects such as digital currency and IoT. However, the security of the existing blockchain technologies built on the classical cryptography depends on the computational complexity problem. With the enhancement of the attackers’ computing power, especially the upcoming quantum computers, this kind of security is seriously threatened. Based on quantum hash, quantum SWAP test and quantum teleportation, a quantum blockchain system is proposed with quantum secure communication. In classical cryptographic theory sense, the security of this system is unconditional since it has nothing to do with the attackers’ computing power and computing resources.

Quantum key distribution with two-way authentication

Quantum key distribution uses the principle of quantum physics to realize unconditionally secure key distribution protocol. But this kind of security needs to be based on the authenticated classical channel. Although there are quantum key distribution protocols without classical channel, authentication is still needed. In the process of key distribution, authentication is not considered, which is also a problem of quantum key distribution protocol. In this paper, a quantum key distribution protocol with two-way authentication is proposed. Identity authentication is carried out at the same time of key distribution. If the identity authentication fails, the key distribution protocol cannot be carried out. If the key distribution protocol is aborted, the identity authentication is not successful. The conclusion of this paper is based on a central authentication system supported by symmetric encryption theory, which uses pseudo-random functions, multiple sets of quantum conjugate bases and Measurement-device-independent technology to simultaneously achieve two-way authentication and key distribution.

Investigation difficulties and optimization suggestions of insider trading criminal cases in securities market

Insider trading crime is a kind of securities and futures crime. With the development of China's securities and futures market, insider trading crime has gradually become the mainstream of securities and futures crime, and presents a high incidence trend. For this kind of criminal suspect, "keep running without missing" business not only infringes the interests of the majority of small and medium investors, but also destroys the normal order of the capital market, which is not conducive to the stable development of the economy during the social transition period in China. China's public security organs in the investigation of evidence is still lacking a lot. The public security organs did not perform the main investigation function. In fact, the main investigation activities are mostly completed by the securities supervision and administration department. Therefore, investigators can perfect the investigation, prevention and control of criminal cases of insider trading in the securities market from the aspects of investigation preparation, selection of investigation route, application of investigation measures and means, collection of evidence and so on.

Political aspects of security of the European Union Member States

Political security is very often considered through the prism of individual states. In the scholar literature in-depth analyses of this kind of security are rarely encountered in the context of international entities that these countries integrate. The purpose of this article is to draw attention to key aspects of political security in the European Union (EU) Member States. The EU as a supranational organisation, gathering Member States first, ensures the stability of the EU as a whole, and secondly, it ensures that Member States respect common values and principles. Additionally, the EU institutions focus on ensuring the proper functioning of the Eurozone (also called officially “euro area” in EU regulations). Actions that may have a negative impact on the level of the EU’s political security include the boycott of establishing new institutions conducive to the peaceful coexistence and development of states. These threats seem to have a significant impact on the situation in the EU in the face of the proposed (and not accepted by Member States not belonging to the Eurogroup) Eurozone reforms concerning, inter alia, appointment of the Minister of Economy and Finance and the creation of a new institution - the European Monetary Fund.

Perceptions of the effectiveness of security measures used at security estates: case studies from Centurion in the city of Tshwane, Gauteng

Residential security estates are built to deliver the kind of security (and personal safety) that residents seek and, from a visitor’s point of view, one of the primary reasons for choosing to live in a security estate. However, incidents of crime continue to be reported as occurring at these sought-after residential security estates. This raises the question whether living in these types of estates can create a sense of complacency in residents and security staff towards the crime problem, influence perceptions of personal safety, and whether current security measures implemented are delivering the requisite security needed to protect and secure the residents living inside these estates, while simultaneously ensuring their overall safety and protection within such a residential estate. In this study, the security measures at the selected security estates, as applied by the security officials and by the residents themselves, were examined in order to assess not only the perceptions of both residents and security personnel concerning the effectiveness and impact of the implemented security measures on security at a residential estate, but also whether security measures were being routinely implemented, practised and enforced by residents and security services alike. If not, why is such implementation being neglected or not being enforced.

PERCEPTION OF SOCIAL SECURITY IN REGIONS OF THE RUSSIAN-ASIAN BORDERLAND (ON THE EXAMPLE OF THE ALTAI REGION)

Social security is an important priority of the State policy, embracing other kinds of security as essential prerequisites for its provision. Sociological surveys based on psychosemantic methodology, fulfilled in one of the regions of Russian-Asian borderland (the Altai region, 2019, n = 75) have found that social security in the region is primarily defined by its population through probability of realization of economic risks — loss of income, livelihoods and creditworthiness, and depends on expression of nutritional and transport risks, risks of fatal diseases, negligence or incompetence of specialists in different fields of social practice. Social-economic instability and distrust towards basic social institutions, responsible for the security and safeguarding the life and health, form negative attitudes of population about social security.

Three Layer Security Model for Distributed Relational Database

Today we are living in a digital world where we all are connected to an open access network to exchange information. This information is more valuable assets that need protection from unauthenticated access. There are many security models has been proposed to protect the data stored in database but still needs more protection from attacks. In this study we have a three layer security model for relational database. Proposed model builds a security architecture based on access control policy, cryptography techniques and stored procedure. These mechanisms and techniques are combined together to present an interactive three-layer security model for securing relational databases in distributed environment. This model provides a kind of security controlling both in rests of database and data in motion from malicious user and other attacks.

Systematic Review on Security and Privacy Requirements in Edge Computing: State of the Art and Future Research Opportunities

Edge computing is a promising paradigm that enhances the capabilities of cloud computing. In order to continue patronizing the computing services, it is essential to conserve a good atmosphere free from all kinds of security and privacy breaches. The security and privacy issues associated with the edge computing environment have narrowed the overall acceptance of the technology as a reliable paradigm. Many researchers have reviewed security and privacy issues in edge computing, but not all have fully investigated the security and privacy requirements. Security and privacy requirements are the objectives that indicate the capabilities as well as functions a system performs in eliminating certain security and privacy vulnerabilities. The paper aims to substantially review the security and privacy requirements of the edge computing and the various technological methods employed by the techniques used in curbing the threats, with the aim of helping future researchers in identifying research opportunities. This paper investigate the current studies and highlights the following: (1) the classification of security and privacy requirements in edge computing, (2) the state of the art techniques deployed in curbing the security and privacy threats, (3) the trends of technological methods employed by the techniques, (4) the metrics used for evaluating the performance of the techniques, (5) the taxonomy of attacks affecting the edge network, and the corresponding technological trend employed in mitigating the attacks, and, (6) research opportunities for future researchers in the area of edge computing security and privacy.

Proposed system is evaluated on various input data containing from various sources. The performance of the proposed system is also compared with the performance of existing system.

Biometric Based on Steganography Image Security in Wireless Sensor Networks

Wireless Sensor Network (WSN) is a rising the innovation that demonstrates incredible guarantees for the different complex applications for both mass open and the military. The detecting for innovation attached with the preparing energy and the remote correspondence the security of biometric data might be compromised by system assaults, showing person’s data without an appropriate insurance isn’t reasonable for approval. The concern of the remote correspondence of the innovation additionally causes different kind of security and dangers in the MANET. The expectation of this paper to examine of the security connected issues and difficulties in the remote sensor organizations utilizing MANET. It is distinguish the security and dangers of survey arranged security instruments for the remote sensor organization. Notwithstanding, encryption and decoding calculations are moderate and contain tedious activities for moving information in system. In this section, by considering remote sensor arranges and confirming server is present another idea called “review” and manages its productivity in managing the security issue in MANET. A “digest” can be gotten from any sort of data attribute through which no one can catch any data of essential biometric qualities. Here demonstrate that this idea prompts the expansion of the precision and availability of a biometric framework.
