Abstract
Enhanced security is provided for cloud based matching systems by using the principle of Independence of Irrelevant Alternatives (IIA). The client uses IIA to transform alternative data before sending it to the cloud, and then does the reverse transformation on the matching results generated by the cloud service provider to rebuild the matching results for the alternative data. Using this protocol, the client does not disclose its own data in a form that is usable by the cloud service provider, and the cloud service provider does not disclose to the client the provider's proprietary coefficient beta information.
