ESSAO: Enhanced Security Service Algorithm using Data Obfuscation Technique to Protect Data in Public Cloud Storage


Background/Objectives: Cloud provides virtual space for users to storage and maintains their data. It mainly helps small and medium scale industries to easy come up and achieve their IT requirements with minimum cost. Apart from this, it has many security related issues. To address the security issues, this paper proposes an enhanced security service algorithm using data obfuscation technique namely ESSAO. Methods/Analysis: The proposed algorithm is provided as a service to user from the cloud. It is based on data obfuscation technique and it obfuscates only the numerical data in the original data. It uses different mathematical methods to convert the original data into unintelligible data. Findings: Cloud provides this proposed ESSAO algorithm as a service to the users based on the demand. This algorithm is coded in Java and hosted in the cloud server for evaluation. ESSAO reduces the time taken for obfuscation and de-obfuscation. It also reduces the size of data after obfuscation. Each numerical value in the original data is converted into a single character value. Hence, the size of data is reduced. It minimizes the latency of data uploaded to cloud. Hence, it is easily adopted in the cloud environment. Obfuscated data in the cloud is not accessible to the cloud service providers or other users of cloud services. Hence, it maintains the security of data in the cloud. Novelty/Improvements: Addressing security to the cloud environment is difficult task. This proposed algorithm provides security to the data in the cloud. This work is more applicable to education, medical, govt. and etc. to secure their data in the cloud.
