Confidentiality of Database for Secure Information in Cloud Computing Using Table Collide Storage Model

Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources. Cloud computing provides computation, software, data access, and storage services that do not require end-user knowledge of the physical location and configuration of the system that delivers the services. Since the data transmission on the internet or over any networks is vulnerable to attack, privacy preservation and data integrity have become two of the most critical security issues related to user data. In conventional paradigm, the organizations have the physical possession of their data and hence have an ease of implementing better data security policies. But in case of cloud computing, the data is stored on an autonomous business party, who provides data storage as a subscription service. The users have to trust the cloud service provider (CSP) for security of their data. Cloud database can be decomposed and placed in different service providers’ servers at cloud computing to secure data from any intruder. Here the challenge lies in security and also placing data at different locations including how, when and where to place in cloud storage to maintain confidentiality. This article describes tables collide storage model with private key table structure, which ensures confidentiality in cloud computing by splitting table into small pieces and implicitly performs encryption through collide different table’s pieces before storing in cloud environment.
