DATA AVAILABILITY IN DECENTRALIZED DATA STORAGE USING FOUR-NODE INTERPLANETARY FILE SYSTEM

Centralized storage is a data model in which stored and managed single physical location or centralized system. In this model, all information are on servers centers by one entity organization. This also has disadvantages such as risk of system failure against distributed denial service (DDoS) attacks, natural disasters, hardware failures causing point failure. threat results loss lack user confidence the availability storage. study proposes to evaluate decentralized using four-node interplanetary file (IPFS) that interconnected with swarm key authentication key. Unlike only center, IPFS allows users upload download from four centers. can avoid dependence central server reduce load. The evaluation show three times more resilient than increase so organizations minimize
