Cloud computing nowadays is dealing with most of security issues and privacy issues, no matter how strong security we use but achieving the 100% security will always a tough notch. However this research deals with area of cloud computing in building the trust level of cloud brokers among the general public or its distributers and buyers. The trust level is achieved by following a novel idea of checking the data manipulation in uploaded content. The SAAS cloud network in general is always secured with encryption so in this part for security NTRU is been implemented. Further this method describes the naive bayes string pattern matching algorithm. The data which is uploaded in server is auto synchronizing for back up onto another server which is a hidden database server. The user doesn’t know that his/her data is kept in this server also whenever the query for download is been generated to download the server the existing data in server is cross verified with hidden database to check the manipulation if any which is accommodated using Naïve Bayes String Search Algorithm. If no data manipulation is been occurred it defines the superiority and trustworthiness of cloud storage among the public and cloud buyers.
