Distributing facts for more than one cloud storage providers routinely offers customers with a certain degree of information leakage control, not for any point of assault can leak all the data. However, unplanned distribution of records chunks can cause hsigh data disclosure even while using more than one cloud. In this paper, we look at critical records leakage trouble resulting from unplanned facts distribution in multicloud storage services. Now we present StoreSim, a data leakage aware storage machine in multicloud. StoreSim ambition is to save syntactically similar records on the same cloud, which minimizes the consumer's facts leakage across various clouds. We layout an approximate set of rules to clearly generate similarity-maintaining signatures for facts chunks based totally on MinHash and Bloom filter, and additionally layout a characteristic to compute the statistics leakage primarily based on those signatures. Subsequently, we present an appropriate storage plan generation algorithm primarily based on clustering for dispensing records chunks with minimal statistics leakage throughout more than one cloud. Eventually, we evaluate our scheme for the use of two real datasets from Wikipedia and GitHub. We show that our scheme can minimize the data leakage by using up to 60% compared to unplanned placement. Furthermore, our analysis on system attackability describes that our scheme makes assaults on facts which are extra complicated.
