Abstract

Cloud computing is defined as the delivery of on-demand computing resources ranging from infrastructure application to datacenter over the internet on a pay-per-use basis. Most cloud computing applications does not guarantee high level security, such as privacy, confidentiality, and integrity of data because of third-party transition. This brings the development of Blowfish cloud encryption system that enables them to encrypt their data before storage in the cloud. Blowfish encryption scheme is a symmetric block cipher used to encrypt and decrypt data. Microsoft Azure cloud server was used to test the proposed encryption system. Users are able to encrypt their data and obtain a unique identification to help them retrieve encrypted data from the cloud storage facility as and when needed.
