Biometric systems (BSs) have shown prominent results in providing secure authentication protocols and a unique identification ecosystem for various applications. Over the years, plentiful research has been done to enhance the security of BSs. However, traditional BSs pose security & privacy concerns related to biometric templates, and the research community has been exploring cryptographic schemes to solve these issues. Particularly, Biometric Cryptosystems (BCSs) can address these concerns and enhance the protection of the biometric template. However, BCSs have several associated challenges which provide many research opportunities. Therefore, this survey focuses on BCS techniques and the various Cryptography schemes used to control the security & privacy issues of the biometric templates. We further investigate the potential security threats in BCS and report various attack vectors. We also present the performance analysis of different BCS schemes. Additionally, we explore the use of Blockchain technology for BCS to provide a robust system over a decentralized network. Based on the analysis and identified limitations, we explored the Decentralization of BCS, which aims to address the current challenges in BCS. We also report some potential use cases and future directions to use BCS in Web 3.0 applications built on Blockchain. Finally, we provide a summary of the most pressing issues that still need to be addressed in order to provide reliable privacy and robust security solutions for BCS.

With the rapid advancement in internet connectivity, Connected Vehicle network is becoming a promising technology in the current years. However, the increased connectivity most often results in intensifying risk of cyber security threats. In this regard, the network of connected vehicle is also vulnerable to various cyber-attacks. This paper discussed the security issues with connected Priority Vehicle. A priority vehicle must ensure the high level of security otherwise, the results would be devastating and the consequences might be very serious. To ensure the safe and secure movement of connected priority vehicle on the road using blockchain technology. In our proposed system, the priority vehicle movement is controlled by blockchain network, and it only accept messages and signals from blockchain authorized nodes. In particular, the priority vehicle's location, speed and travel time are the important parameters that we secure using blockchain network. This paper also discusses the possible attacks on the priority vehicles and show how our solution can mitigate these attacks. Here it justifies the effectiveness and performance of our security solution using simulation and proves that the blockchain technology shows the potential application towards securing the information in the connected vehicle network.
