Client safety and privacy will be maintained through secure security access systems, which are necessary in light of the great dependence on digital benefits. During the age of digital help, secure and confidential access control is most important for customers as well as providers. Through guaranteeing that only clients possessing specific resources are certified, access control ensures secret data and discourages unlawful actions. Widespread centralized authorization systems usually expose users' sensitive data, enabling data breaches, abuse, and espionage. To solve all of the above problems and establish a trust less system in which clients can provide access to their data or services without revealing sensitive information, we propose a decentralized code that is used to establish an authorized, secure, private, and scalable service access. Decentralized technologies such as blockchain and distributed ledgers are employed within this system. By decoupling authorization from centralized organizations, the Inter-Planetary File System (IPFS) enhances user control over personal information, diminishes the attack surface for service providers, and enhances client privacy. The protocol is secure and accommodates a broad set of service providers, ranging from digital platforms to decentralized apps, and utilizes cryptographic methods such as symmetric encryption and proxy re-encryption to see that only approved recipients have access to specific resources. This provides perfect access control while maintaining client data security. The decentralized access control and zero knowledge proof architecture is explained here along with its primary security and privacy features and uses to file storage and service scenarios.
