Cloud storage is nowadays trending in case of storage and the cloud service providers (CSP) provides varieties of offers for organisations and made the resources available online. Data integrity checking and regeneration of failed servers nowadays becomes critical and we need to safeguard the delegated data in cloud storage against corruptions. It will become the major delinquent towards the cloud servers. Surviving paper works offers only private auditing and requires data owners to always available and handle auditing, and repairing which may sometimes be unrealistic. Our work-scheme focuses with regeneration and for that cloud user’s first produce their secret keys and the TPA audits the files, in case of file corruption then forwards to a proxy agent by sharing partial private key and regenerates the corrupted files. Here we uses the seed block algorithm for the purpose of regeneration and also introduces an additional agent for auto regeneration, which reduces the downloading time related issues.
