Secure Auditing For Outsourced Data in Cloud Using Homomorphic Token and Erasure Code

N.S. Monalisa Devi, T. Sounder Rajan

Cloud Computing is the process of providing computer resources like hardware and software as a service on-demand. It also provides remote services with a user's data and software Cloud Computing is the result of evolution and adoption of existing technologies and paradigms. The existing work presented a dynamic audit service for verifying integrity of un-trusted and outsourced storage. Audit service is constructed based on fragment structure, random sampling and index-hash table. Support provable updates to outsourced data and timely anomaly detection. Probabilistic query and periodic verification method is introduced. In proposed, secured auditing system for cloud data storage with Error Corrections Guarantees Storage using homomorphic token and distributed erasure-coded data. Allows users to have audit cloud storage resistance to threats for auditing with minimal communication and computation cost.
