A framework to supply a secure cloud database that will guarantee to prevent security risks and Secret key to pre-process the file. Multi-cloud will be implemented as hybrid cloud. This framework will apply the use of secret sharing algorithm, MAC algorithm, audit protocol for outsourced data to reduce the risks of data intrusion, loss of service availability and ensures data unity. Muti-cloud usage is implemented by distributing data into three different cloud providers. The public Demonstrable Data Ownership (DDO), which is a cryptographic technique for verifying the unity of data without retrieving it at an untrusted server; can be used to realize audit services.
