Secure APK Installation Using Block Chain: A Decentralized Approach to Threat Prevention

Abstract

The rapid proliferation of mobile applications has heightened security concerns related to malware infections, data breaches, and unauthorized access. Traditional security mechanisms primarily rely on centralized verification models, which introduce vulnerabilities such as tampering, single points of failure, and slow response times to emerging threats. This paper introduces a blockchain-based approach for secure APK installation, incorporating immutable records, decentralized verification, and real-time threat detection. The proposed framework integrates machine learning for dynamic behavioral analysis and smart contracts to enforce security policies automatically. By leveraging blockchain, the system ensures the integrity of APKs, verifies developer authenticity, prevents tampering, and enables a collaborative threat intelligence network for real-time security updates. Furthermore, the decentralized nature of blockchain eliminates reliance on centralized authorities, providing a transparent, efficient, and tamper-proof APK verification mechanism. The focus will be on optimizing blockchain consensus mechanisms, advancing smart contract functionalities, and integrating AI-powered threat intelligence for dynamic cybersecurity.
