Paper Title
Efficient and Secure Keyword Search over Cloud Database

Cloud Computing becomes prevalent, more and more sensitive information is being outsourced to the cloud, such as emails, personal health records, company finance data, and government documents, etc. To provide the security in information retrieval this paper proposes a novel model i.e. “Secure Search using ACO (SS-ACO)”. This paperimplements ACO algorithm which is probabilistic technique for solving computational problems and finds paths through graphs by imitating the ants’ search for food. For security purpose this model uses searchable encryption (SE). Searchable Encryption scheme is a cryptographic technique that allows search of specific information in an encrypted content. For the proposed security model, the performance analysis demonstrates that this model provides security while query searching,it is reliable and confidentiality is maintained.
