Data Swapping In Cloud Computing

Abstract

In the modern era of fast computing data storage and data retrieval is occurred due to cloud computing. Cloud computing is a pool of com- puting resources available on demand with the use of internet. it is a term used for the consumption of utility computing resources. it is used to maximize the effectiveness of the shared resources which is currently available on cloud. it relaxes the companies from investing money on heavy infrastructure rather they can used the same resources on shared basis..in the wide use of cloud computing threat comes to storage of data in the cloud server as it not known to the cloud user where there data will be stored they usually reluctant to store their data on cloud. to gain their trust cloud providers are facili- tating various user confidentiality methods to stored their data..one technology is being used is data swapping. it is a strategy for protecting the micro data confidentially which is yet to be released. the purpose of data swapping is to create uncertainty in the minds of the intruder. it is a method to adjust the data values by swapping fraction of records between the records so that the intruder won't get the actual data rather gets scrambled data.
