The influence of thermally induced cholesteric liquid crystal structural colour for information encryption

ABSTRACT Cholesteric liquid crystal (CLC) is particularly remarkable due to its ability to exhibit structural colour. Structural colour materials offer solutions for information encryption that feature good stability, ease of perceivability, and arbitrary patterns. This work investigates the temperature-dependent variation of CLC structural colour and provides a quantitative analysis of the pitch and helix twist power (HTP) at different temperatures, further exploring its potential applications in information encryption. By recording quick response (QR) code patterns in the LC Polymer of the LC cell, single-pattern and dual-pattern LC cells are prepared, and their applications in information encryption are demonstrated. The QR pattern will be hidden or revealed as the temperature changes by CLC in the LC cell. Additionally, dual-pattern encryption requires polarisers to address the crosstalk issue under white light, making the LC cell a safer solution for access control systems. These results lay a theoretical foundation in CLC stimulus-responsive structural colours and offer valuable insights in information security and anti-counterfeiting applications.

Evaluation of Control Activities in the Inventory Purchasing System (Case Study at PT. GSI)

Purchasing inventory is a critical aspect of the production process in any company. PT GSI conducts purchasing from suppliers to meet its production needs. This research aims to evaluate the control activities of the inventory purchasing system implemented at PT GSI. Using a qualitative approach, interviews were conducted with relevant departments to gather data. The study evaluates the system based on the COSO framework, which revealed several inconsistencies. A significant finding is that there is no adequate separation of duties at PT GSI, with administrative and financial tasks often handled by the same staff. Additionally, there is a lack of access control to the system, as tasks are still performed manually without sufficient safeguards. The research suggests that improvements are needed in terms of task separation and system access control to align with COSO standards. Implementing these improvements would help PT GSI minimize risks such as fraud and operational inefficiencies. Moreover, operational control would be better facilitated, ensuring smoother processes without interruptions. This study emphasizes the importance of internal control systems, especially in purchasing operations, to prevent potential financial and reputational losses. Ensuring compliance with COSO and other industry standards would enhance the company's overall operational effectiveness.

An Efficient Multilayer approach for Securing E-Healthcare Data in Cloud using Crypto – Stego Technique

Healthcare data has been moving to cloud platforms in recent years, which has increased accessibility and scalability but also raised security issues. Ensuring data integrity and safeguarding private health information from unwanted access are critical. This paper presents a comprehensive strategy to integrate effective Elliptic Curve Cryptography ECC-AES with steganography techniques to improve the security of healthcare data in the cloud. ECCAES is especially well-suited for cloud situations with limited resources since it provides strong security with reduced key sizes. Confidentiality is guaranteed by encrypting healthcare data using ECC- AES before storage, reducing the possibility of data breaches. Steganography techniques are also integrated to improve security against skilled adversaries by adding an extra degree of obfuscation by concealing encrypted data inside innocuous files or images. Strict key management procedures, access control systems, and frequent security audits are important components of the proposed system that ensure adherence to Health Insurance Portability and Accountability Act (HIPAA) and General Data Protection Regulation (GDPR) compliance requirements pertaining to healthcare data protection. Programs for employee awareness and training are also crucial for reducing the likelihood of human mistakes. Healthcare businesses can safely use cloud technology while protecting patient data integrity and privacy by putting in place multi-layered security safeguards.

Enhanced multimodal biometric access control system using chicken swarm optimization and self-organizing feature maps: a study on ear and iris recognition

Access control systems are crucial for securing sensitive data and system components by allowing authorized access while blocking unauthorized entities. Traditional unimodal biometric systems, make use of a single physiological or behavioral trait, have limitations such as susceptibility to spoofing and environmental constraints, leading to reduced reliability. This study explores an enhanced multimodal biometric access control system that combines ear and iris traits using an enhanced Self-Organizing Feature Map (SOFM) algorithm improved with Chicken Swarm Optimization (CSO). The system's performance is evaluated against traditional SOFM, with a focus on recognition accuracy and processing time. The data used to train the classifier for this study were collected from 190 individuals, encompassing a total of 2,280 images of iris, and ear traits. Preprocessing involved cropping, resizing, and grayscale conversion using histogram equalization. Feature extraction utilized Local Binary Patterns (LBP), followed by feature fusion at the feature level to create an integrated feature set. The enhanced SOFM algorithm was then applied for classification, with the CSO technique optimizing the learning rate and weight parameters for improved performance. At different thresholds, the CSO-SOFM classifier outperformed the standard SOFM classifier using metrics such as Sensitivity, Specificity, Precision, Accuracy and Recognition time.

Emergency Medical Access Control System Based on Public Blockchain

IT has made significant progress in various fields over the past few years, with many industries transitioning from paper-based to electronic media. However, sharing electronic medical records remains a long-term challenge, particularly when patients are in emergency situations, making it difficult to access and control their medical information. Previous studies have proposed permissioned blockchains with limited participants or mechanisms that allow emergency medical information sharing to pre-designated participants. However, permissioned blockchains require prior participation by medical institutions, and limiting sharing entities restricts the number of potential partners. This means that sharing medical information with local emergency doctors becomes impossible if a patient is unconscious and far away from home, such as when traveling abroad. To tackle this challenge, we propose an emergency access control system for a global electronic medical information system that can be shared using a public blockchain, allowing anyone to participate. Our proposed system assumes that the patient wears a pendant with tamper-proof and biometric authentication capabilities. In the event of unconsciousness, emergency doctors can perform biometrics on behalf of the patient, allowing the family doctor to share health records with the emergency doctor through a secure channel that uses the Diffie-Hellman (DH) key exchange protocol. The pendant’s biometric authentication function prevents unauthorized use if it is stolen, and we have tested the blockchain’s fee for using the public blockchain, demonstrating that the proposed system is practical.

Face Recognition-Based Surveillance System in Mining Industry

Access control in mining construction areas is crucial for the operations of mining companies. This access control functions to secure and restrict unauthorized parties from mining activities. Violations of access rights in the mining industry result in significant losses for companies. This access control can also be utilized to record employee attendance, serving as input for the contract work system commonly applied in mining areas. Closed-circuit television (CCTV) is commonly used to monitor activities; however, the current use of CCTV still requires direct human observation, which may result in important events being overlooked. The functionality of these CCTVs can be enhanced to manage access rights and monitor employee attendance to support company operations through face recognition methods. In this study, a system design was carried out through a research approach to determine the technology to be used in the system. The development of a face recognition-based access control system was conducted based on system engineering methodology. This development includes system requirements analysis, the design of a face recognition-based access control system, implementation, and system performance evaluation. The resulting system was tested through simulation processes based on actual field conditions, and the test results showed that the system could recognize faces registered in the dataset and identify subjects not registered in the dataset with an accuracy of 60%, precision of 96%, recall of 58%, and an F-score of 72%. Additionally, the system was able to connect to a database to store face recognition results and then display them on an employee attendance monitoring dashboard. The delay between the face recognition system and actual time ranged from 2-4 seconds and was still tolerable.

Towards accountable and privacy-preserving blockchain-based access control for data sharing

The integration of blockchain technology with Access Control (AC) systems presents novel opportunities for enhancing data security within decentralized architectures, which is drawing increasing attention in Data Sharing (DS) applications. However, existing works reveal a gap in achieving accountability for anonymous access in the absence of a centralized trusted authority. To address this issue, this paper introduces InvisiReveal, a novel Blockchain-Based AC (BBAC) framework that achieves permission invisibility, access anonymity, and accountability without extra trust assumptions. Users in InvisiReveal generate anonymous credentials to authenticate their requests using Zero Knowledge Proof. To enable accountability, a novel blockchain-oriented verifiable commitment (BC-VC) protocol is designed that allows a user to commit a confidential traceable tag to the blockchain. The system could unveil a malicious requester’s identity by opening the tag commitment under collaboration with the victim user and blockchain. We implement a prototype of InvisiReveal to evaluate its practicality, where an access request is verified within 5 ms.

Context-Aware Risk Attribute Access Control

Traditional access control systems exhibit limitations in providing flexible authorization and fine-grained access in the face of increasingly complex and dynamic access scenarios. This paper proposes a context-aware risk access control model to address these challenges. By developing a multi-level contextual risk indicator system, the model comprehensively considers real-time contextual information associated with access requests, dynamically evaluates the risk level of these requests, and compares the outcomes with predefined risk policies to facilitate access decisions. This approach enhances the dynamism and flexibility of access control. To improve the accuracy and reliability of risk assessments, we propose a combination weighting method grounded in game theory. This method reconciles subjective biases and the limitations of objective data by integrating both subjective and objective weighting techniques, thus optimizing the determination process for risk factor weights. Furthermore, smart contracts are introduced to monitor user behavior during access sessions, thereby preventing malicious attacks and the leakage of sensitive information. Finally, the model’s performance and authorization granularity are assessed through empirical experiments. The results indicate that the model effectively addresses the requirements of dynamic and fine-grained access scenarios, improving the system’s adaptability to risk fluctuations while safeguarding sensitive information.

This paper presents a concise yet effective approach to address the challenge of anti-face spoofing using Python within a limited codebase of 50 lines. The proposed solution leverages a combination of image processing techniques and machine learning algorithms to detect and prevent face spoofing attempts. A pre-trained deep neural network model for facial recognition is employed to extract essential facial features. Subsequently, the system utilizes image manipulation detection methods to identify anomalies indicative of face spoofing attacks. The implementation showcases the simplicity and efficiency of the proposed anti-face spoofing technique, demonstrating the potential for integration into real- world applications with minimal computational overhead. The concise Python code enables easy adoption and adaptation for developers aiming to enhance the security of facial recognition systems against face spoofing threats. The experimental results demonstrate the effectiveness of the approach in accurately distinguishing between genuine and spoofed facial images, thereby contributing to the robustness of facial recognition systems in the presence of adversarial attacks.
