Stand-in Backdoor: A Stealthy and Powerful Backdoor Attack

Lack of transparency in deep learning models makes them vulnerable to backdoor attack, which can cause severe security consequences. For a backdoored model, the specific inputs can trigger misclassification rules while it performs normal behaviors on clean data. Existing backdoor attacks usually generate poisoned data by adding an obvious trigger to the original data and mislabeling them, which suffers from poor invisibility and hence can be easily detected. In this paper, we propose Stand-in Backdoor, a more stealthy and powerful backdoor attack, which can completely hide the trigger while maintaining correct labels of poisoned data. Specifically, we design a novel optimization strategy to transform triggers into imperceptible perturbation in the feature space. Furthermore, utilizing the transferability of feature perturbation, we fine-tune the victim model with well-constructed poisoned data that are correctly labeled. Extensive experiments conducted on various image classification tasks demonstrate that our attack outperforms the state-of-the-art work in terms of backdoor stealth and attack performance, without sacrificing the model&#x0027;s utility.

A New Reactive Framework for Web Using Data Analaysis

Creating a Web Personalization system is the process of tailoring a website to meet the specific requirements of an individual user or a group of users. To create accurate predictions about users' future movements, association rule mining and sequential pattern finding are some of the approaches it employs, clustering, and classification, among others. Recent approaches for online customization have fallen short in terms of accurately predicting user interests. An innovative online customization approach has been created in order to give useful suggestions. A website's web pages must be given suitable weights, and this is the foundation of the suggested work. In order to do this, we employed the distance measure of the visit relationship as well as the occurrence frequency measure of web pages. The technique makes use of an improved graph-based partitioning algorithm for grouping web pages and classifying the current user actions more precisely than previous approaches. When making a judgement between web sites for the purpose of recommendation, a Threshold value is employed. Our testing findings show that accuracy is around 61 percent, coverage is approximately 34 percent, and F1 measure is 44.23 percent. It contributes to the enhancement of the user's browsing experience.
Agro-Allied Small and Medium Enterprises and the Economy of Kogi State, Nigeria

This paper focused on Agro-allied Small and Medium Enterprises and the economy of Kogi State, Nigeria.

Smart Door Camera with Facial Recognition Feature for Thermal Screening

Abstract: In these times of COVID-19, it is essential to go through thermal screening for checking one’s body temperature before entering any premises. However, it is a tiring process as it involves measuring body temperature of all people, one at atime. At the same time, those who carry out thermal screening are required to stand for more than 8 hours a day and check each and every person. This takes a lot of time and effort. So to come up with a solution that can do this job effortlessly, we have built a Facial Recognition Thermal Screening System. The device works by recognizing the face of each person and doing thermal screening to detect the body temperature. If a person is found to have a very high temperature, then the systemwill not allow entry and instead will automatically notify that person to take a COVID-19 test. If the body temperature falls between the required normal temperature range and is found to be okay, then entry is allowed after proper sanitization Keywords: Face Recognition, Covid-19, Thermal Scanning, Raspberry-pi, Thermal Sensor .The temporal variations present in thermal face images are mainly due to different environmental conditions, physiological changes of the subjects, and differences of the infrared detectors’ responsivity at the time of the capture, which affect the performance of infrared face recognition systems. To perform this paper, we created two thermal face databases that include capture sessions with real and variable conditions. We also propose two criteria to quantify the temporal variations between data sets. The thermal face recognition systems have been developed using the following five methods: local binary pattern (LBP), Weber linear descriptor (WLD), Gabor jet descriptors, scale invariant feature transform, and speeded up robust features. The results indicate that the local matching-based methods (WLD and LBP) are mostly immune to temporal variations, which is noticeable when the face images have been acquired with a time lapse, while the rest of the methods are clearly affected and are not suitable for practical infrared face recognition.

Dynamic Fractal Mathematical Model

Matter structure (atoms and molecules) represents a material's physical properties. Hence, matter structure study provides new materials and new properties. Generally, the matter structure investigation approach is stationary (neglects time) because of the unpredictable movement of particles. Currently, the untraceable movement of particles is assumed chaos, and probability is the most efficient mathematical approach for studying. But, nanoparticles harmonic behaviors show matter as a system. In other words, it seems nanoparticles are fractals, not fragments. Therefore, a novel doctrine is necessary. In this article, the matter system approach and dynamic topology provide the Dynamic Fractal mathematical model that represents the dynamic structure of matter. Due to crystals' strong dependency on material structure, this doctrine could be significant for crystal and crystallization analysis. Then, more efficient products of industries as semiconductors, cutting machines, laser technology, watch industry, photovoltaic cells will be expected.

An overview on cyber crime

The body of data is now processed online, making it susceptible to cyber-attacks. There are a large variety of cyber dangers, and whose behavior is hard to predict early on, making it tough to prevent cyber assaults in their early stages. Computer assaults may have a purpose or may be handled without the user's knowledge. Attacks that are carried out intentionally are classified as cybercrime, and they have serious ramifications for society in the form of economic disruption, psychological disturbance, and a danger to national security, among other things. Cybercrime prevention needs a detailed examination of criminal conduct as well as an awareness of their implications at different levels of society. As a result, the present paper offers a knowledge of cybercrime and its social effects, as well as future cybercrime trends.
Integrating Information Flow Analysis in Unifying Theories of Programming

This paper presents a formal approach for modelling and reasoning about information flow control in software systems under Hoare and He's Unifying Theories of Programming (UTP). We investigate the problem of integrating information flow control into system design in a unified semantic setting. Our approach can therefore treat information flow analysis and control in various families of specification languages and programming paradigms in a more general way. In addition, we formalise the link between classes of predicates as a paired function which maps set of the predicates from one class into set of the predicates from the other with a concern of flow security preservation. The proposed flow-sensitive combined theories of multiple level classes of predicates can be applied to ensure flow security in different paradigms under stepwise development.
