Abstract

The increasing reliance on digital platforms for public administration has heightened concerns about data security in e-government systems. Cyber threats, unauthorized access, and data breaches pose significant risks to the integrity and confidentiality of sensitive governmental information. Blockchain technology, with its decentralized and tamper-proof nature, offers a promising solution for enhancing data security in e-government systems. This research explores the use of blockchain to safeguard data in e-government platforms, focusing on its potential benefits, challenges, and implementation strategies. The study adopts a mixed-method approach, combining a systematic literature review and expert interviews. The literature review analyzed 50 academic articles and industry reports, while interviews with 10 blockchain experts provided practical insights. Key factors such as data integrity, transparency, and access control were evaluated to determine blockchain’s effectiveness in addressing e-government security challenges. The findings reveal that blockchain significantly improves data security by ensuring immutability, enabling secure data sharing, and reducing reliance on central authorities. Experts highlighted blockchain’s potential to enhance transparency and accountability while maintaining privacy through cryptographic techniques. However, challenges such as high implementation costs, scalability issues, and regulatory uncertainties were identified as barriers to adoption. The study concludes that blockchain can revolutionize e-government data security by offering a robust and decentralized framework. Addressing the challenges of implementation and policy alignment will be critical for realizing its full potential. Future research should focus on pilot projects and sector-specific adaptations to accelerate blockchain adoption in e-government systems.

Abstract

quantum computing. However, the main challenge in creating a scalable quantum computer involves overcoming the technical and physical obstacles of manipulating and maintaining stable quantum states. This research aims to identify and map potential pathways that could lead to the realization of scalable quantum computing. This research explores various approaches in Quantum Optics that can support scalability in quantum computing, focusing on innovations in quantum state control techniques, more efficient system design, and the development of new materials. The methods include comprehensive literature analysis, laboratory experiments, and mathematical modelling. The literature analysis aims to identify recent advances and shortcomings in current techniques. Experiments were conducted to test the feasibility of newly developed techniques in controlling quantum states, while mathematical modelling was used to predict system performance under various operational conditions. This study's results show that using phase and amplitude modulation techniques in quantum state settings offers increased stability and reduced errors. Additionally, new nano-based materials show the potential to enhance interactions between qubits, which is crucial for scalability. This research concludes that combining more advanced state control techniques with innovative materials could significantly advance the prospects for scalable quantum computing. Further research aimed at systems integration and automation of quantum state control is needed to overcome the remaining obstacles.
