Cloud computing has evolved from virtualization, utility computing and client-server architectures and is an extension of service oriented architectures. It has been referred to as a disruptive technology which has implications on a host of issues such as licensing, scalability, cost and performance measures, privacy and security. The authors propose in this paper a flexible distributed storage integrity auditing mechanism, utilizing the homomorphic token and distributed erasure-coded data. Their method achieves the integrity of storage correctness guaranty and identification of misbehaving servers i.e., whenever data modifications or deletions have been detected during the storage correctness verification and error localization across cloud servers.
