Secure Data Storage System and Data Leakage Detection

Abstract

Data transmitted across these networks must be secure and private given how large and rapidly expanding they are. Cloud servers are a key resource for data storage. Therefore, cloud servers must be protected and cannot be left open to the prospect of being utilized by hackers for theft or exposure. They require strategic plans for this to guarantee the data's security and privacy. The solution being proposed makes use of three approaches to guarantee data security. The plans involve data encryption, data distribution across several clouds, and granting data sharing authenticity by using a secret key alone. The system is first set up to allow data sharing across a secure channel of encryption using the Lightweight method. After that, data is dispersed among several clusters using the DROP technique, and data is replicated between clouds to prevent any loss. Only a third private key can explicitly grant those with a need for the information access to various data segments. Any unethical request to share data is detected by a trapdoor, which blocks the request and identifies the individual responsible for any data leakage.
