Multi-keyword based sorted querying over encrypted cloud data

Cloud computing creates a versatile workspace in which anything can be stored and referenced at any time. Adopting this technology means all the sensitive information must be encrypted prior to storage to overcome the security issues. The problem lies in querying the encrypted data. The existing system supports only exact keyword search which makes effective searching a very challenging task. Multi-keyword based Sorted Querying provide an effective mechanism for searching over encrypted cloud data by maintaining the keyword privacy and by tolerating the spelling mistakes and keyboarding error in the user input. This solution supports multi-keyword querying where the searching result is sorted according to the relevance criteria of occurrence of keywords in input sequence.
