This document proposes a patient self-driven multi-stage confidentiality safeguard supportive verification scheme (PSCSV) for distributed mobile health care cloud computing systems. The PSCSV allows patients to authorize different access privileges to physicians located across various health care providers. It establishes multi-level privacy-preserving cooperative authentication through an access tree supporting flexible authorization thresholds. The PSCSV enhances security and anonymity by associating it with cryptographic problems and the number of patient attributes. It aims to efficiently manage access control and protect patient privacy and confidentiality at three different authorization levels: directly authorized physicians, indirectly authorized physicians, and unauthorized individuals.
