High-Dimensional Conditional Covariance Matrices Estimation Using a Factor-GARCH Model

Estimation of a conditional covariance matrix is an interesting and important research topic in statistics and econometrics. However, modelling ultra-high dimensional dynamic (conditional) covariance structures is known to suffer from the curse of dimensionality or the problem of singularity. To partially solve this problem, this paper establishes a model by combining the ideas of a factor model and a symmetric GARCH model to describe the dynamics of a high-dimensional conditional covariance matrix. Quasi maximum likelihood estimation (QMLE) and least square estimation (LSE) methods are used to estimate the parameters in the model, and the plug-in method is introduced to obtain the estimation of conditional covariance matrix. Asymptotic properties are established for the proposed method, and simulation studies are given to demonstrate its performance. A financial application is presented to support the methodology.

The Practicality of Adopting Blockchain-Based Distributed Identity Management in Organisations: A Meta-Synthesis

Blockchain has become an irresistible disruptive technology with the potential to innovate businesses. Ignoring it may in itself result in a competitive disadvantage for organisations. Except for its original financial application of cryptocurrency, more applications are being proposed, the most common being supply chain management and e-voting systems. However, less focus is made on information and cybersecurity applications of blockchain, especially from the enterprise perspective. This paper addresses this knowledge gap by exploring blockchain as a use case for identity management in the context of an organisation. The paper gives a comprehensive background aiming at understanding the topic, including understanding whether claims made around it, especially blockchain’s potential to address identity management challenges, are based on facts or just a result of hype. Meta-synthesis was used as a research methodology to summarise the 69 papers selected qualitatively from reputed academic sources. The general trend shows theoretical evidence supporting some of the claims made but not necessarily friendly to the enterprise context. The study reveals a promising but immature state of blockchain, consequently questioning whether adopting blockchain-based distributed identity management in organisations is fully practical. A research model called TOE-BDIDM is proposed to guide further investigation.

A Review on Secure Data Transmission for Banking Application using Machine Learning

Security on the Internet of Things (IoT) accentuates safeguarding the Internet-empowered devices that connect to remote networks. IoT Safety endeavors to shield IoT gadgets and frameworks against cybercrime, and it is considered a vital security element linked to the IoT. Conversely, banking applications are dynamically being regulated for their inability to give an adequate level of client assistance and insure themselves against and react to digital assaults. One of the primary components for this is the weakness of Fintech systems and organizations to breaking down. Therefore, wireless organizations covering these IoT items are incredibly unprotected. IoT is a lightweight framework, and it is ideal when utilizing lightweight and energy-effective cryptography for assurance. Deep learning is a proficient technique to examine dangers and react to assaults and security occurrences. So this business locales both security and energy productivity in IoT utilizing two novel strategies helped out through the deep learning. This work adds to the most inventive method of saving energy in IoT gadgets through diminishing the utilization of energy-costly '1' values in the interface of Dynamic RAM. This should be possible by utilizing Base + XOR encoding of information during information transmission. Utilizing Conditional Generative Adversarial Network (CGAN) based deep learning strategy, the Base + XOR encoding technique and C.X.E. are prepared or trained quite well in the banking/financial application. The information age in CGAN is done dependent on rules delivered utilizing the generator model. This work is ended up being burning-through less energy, less information transmission time, and gives greater security when thought about the existing frameworks.

Financial management efficiency of islamic boarding school based on information technology

Utilization of information technology is a very important requirement for every component of society. Easy, fast and accurate data and information access can optimize routine daily work. Mawaridussalam Islamic boarding school Batang Kuis as an Islamic education institution that plays a role in shaping the character and personality of the next generation of the nation is expected to be able to optimally manage finances and provide good service to the academics of the Islamic boarding school. Until now, financial management is still done manually using bookkeeping, there is no specific financial application used in Islamic boarding school financial management, so it is difficult and slow in recording, processing, controlling and reporting financial activities. Based on these problems, an application is needed that can be used by the treasurer and board of boarding school leaders for financial management systematically. The method applied is the User Centered Design approach and the target that was successfully achieved is the availability of web-based financial management applications that are used properly to increase the efficiency and effectiveness of financial management in Islamic boarding schools.
