Abstract
An obfuscated policy data encryption system and method for re-encrypting data to maintain the confidentiality and integrity of data about a user when the data is stored in a public cloud computing environment. The system and method allow a user to specify in a data-sharing policy who can obtain the data and how much of the data is available to them. This policy is obfuscated such that it is unintelligible to the cloud operator and others processing and storing the data. In some embodiments, a patient species with whom his health care data should be shared with and the encrypted health care data is stored in the cloud in an electronic medical records system. The obfuscated policy allows the electronic medial records system to dispense the health care data of the patient to those requesting the data without disclosing the details of the policy itself.
