Security of data stored in the cloud is most important challenge in public cloud environment. Users are outsourced their data to cloud for efficient, reliable and flexible storage. Due the security issues, data are disclosed by Cloud Service Providers (CSP) and others users of cloud. To protect the data from unauthorized disclosure, this paper proposes a confidentiality technique as a Security Service Algorithm (SSA), named MONcryptto secure the data in cloud storage. This proposed confidentiality technique is based on data obfuscation technique. The MONcrypt SSA is availed from Security as a Service (SEaaS). Users could use this security service from SEaaS to secure their data at any time. Simulations were conducted in cloud environment (Amazon EC2) for analysis the security of proposed MONcrypt SSA. A security analysis tool is used for measure the security of proposed and existing obfuscation techniques. MONcrypt compares with existing obfuscation techniques like Base32, Base64 and Hexadecimal Encoding. The proposed technique provides better performance and good security when compared with existing obfuscation techniques. Unlike the existing technique, MONcrypt reduces the size of data being uploaded to the cloud storage.
