Outsourcing data to cloud environments can offer ease of access, provisioning, and cost benefits, but makes the data more vulnerable to disclosure. Loss of complete control over the data can be offset through encryption, but this approach requires an omniscient third party key authority to handle key management, increasing overhead complexity. We present the ZeroVis framework that provides confidentiality for data stored in a cloud environment without requiring a third party key manager. It combines fine-grained access control with the ability to search over encrypted data to allow existing applications to migrate to cloud environments with very minimal software changes, while maintaining data provider control over who can consume that data.
