Confidentiality Technique to Encrypt and Obfuscate Non-Numerical and Numerical Data to Enhance Security in Public Cloud Storage
S. Arul Oli, L. Arockiam · 2017
Modern technologies witness lot more developments. Cloud Computing (CC) is one of the rapid developments. The demands, the importance and the usage of CC is on the increase every day. As the importance is on the increase, so is the security problems and its threats. The problems in CC make huge impacts on the developments and its popularity. In CC, the data storage has become an indispensable dimensions. The data stored could be either numeric or non-numeric. These data need to be protected with confidentiality measures before storing it in the CC. The encryption method comes into an aid for depositing the data into cloud database. The cryptographic techniques are used to enhance the security. This paper proposes a CT to enhance confidentiality of numerical and non-numerical data in cloud through AO_ARO_EncObfus_CT. The technique is used by obfuscation and encryption methods. This paper also proposes the technique to enhance security level. The paper produces minimum time, data size and service while uploading into the cloud storage.
