Cloud computing is a widely accepted technology that delivers many services over internet. The services includes storage, easy access from anywhere at any time and also minimum device memory utility. In order to provide security and privacy of data many authorization schemes are used. OAuth scheme is one of the most commonly used authorization scheme. But it cannot be used in the case of heterogeneous clouds. To overcome this difficulty, fuzzy authorization scheme was proposed. In this scheme, modified Cipher-text Policy-Attribute Based Encryption (CP-ABE) and OAuth schemes are used. This scheme provides the facility for an application that is present in one cloud party to access data that is stored in another cloud party.
