摘要：Cloud computing popularity increased from past several year in huge manner. Cloud computing is a type of computing that relies on sharing resources in compare to based on local servers or personal devices to handle applications. Presently implementation of cloud computing has increased rapidly in IT industry and in other organization also. Cloud is a collection of number of dedicated distributed database. Cloud computing having number of benefit over previous single database such as low cost and accessibility of data. If a data is store only at single place and unfortunately that data has been lost then there is no recovery of data. Cloud computing having one more benefit such that we can store more than one copy of data, in this manner if a data is going to be loss at one place that can be retrieved from other place. The problem of service unavailability has been solved by using cloud computing, which was a major concern in single cloud. In cloud computing auditing service for user also becoming a major issue. When a client is interacting with the cloud it having no physical association with cloud for a long time, in this case security issue took a major threat for cloud computing. For this we propose a novel technique that is Auditing service which ensure the integrity and availability of outsourced data in cloud computing. Here we are going to propose Provable Data Possession(PDP) which using cryptography technique for data possession in cloud computing. Here we will also show that cost for auditing data by using PDP is less than the previous one. This technique will best for untrusted server for realizing the security threat which effect the integrity of data into cloud. In this paper we will show auditing service using by Provable data procession technique. It also use some encryption technique.
