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.
