Algorithm for Document Integrity Testing Pre Upload and Post Download from Cloud Storage

This era is of business and marketing, those who have no proper equipments, they can also proceed in this field. This is just because of cloud computing. Many organizations are still in ambivalence whether to adopt cloud computing or not. The biggest barrier before them is security of their sensitive data. This research paper is an attempt to encourage such organizations or individuals who are still thinking to adopt this fruitful as well as cheap and best service. In this paper we have proposed an integrity testing algorithm which tests whole documents at character level before uploading to cloud storage and after downloading from cloud storage. The idea of the algorithm resembles to the idea of ‘error detection and correction’. For more clearance of the idea refer future scope.
