Layer-Based Encrypted Deduplication for Secure Cloud Data Storage

Abstract

LSDedup gives a stratified secure deduplication approach for cloud storage, safeguarding information
confidentiality while enhancing garage performance. conventional deduplication techniques necessitate get
right of entry to to unencrypted information, which gives privacy issues, whereas LSDedup facilitates
deduplication on encrypted files without compromising sensitive information. files are labeled into Strictly
exclusive (SCFiles) and much less confidential (LSFiles) based totally on their sensitivity ranges. SCFiles are
encrypted with the advanced Encryption standard (AES) for better security, whereas LSFiles employ
Convergent Encryption (CE), allowing the deduplication of identical data without the want for decryption. A
proof of work (PoW) mechanism is implemented to address the misrepresentation of record secrecy in cloud
servers, as a result making sure transparency and safety. A safe keyword-based search method is created to
facilitate efficient file retrieval while maintaining statistics privacy. This approach produces encrypted
trapdoors for key-word-centric searches, obstructing illegal access to search queries and file contents. The
counseled system optimizes storage optimization via deduplication and gives a comprehensive approach for
secure data control and retrieval in cloud environments. LSDedup achieves an most beneficial equilibrium
among security and efficiency in cloud storage systems through the integration of encryption, proof of work
validation, and safe search algorithms
