【 摘 要 】

Abstract In view of the problem of resource waste caused by the repeated storage of medical data, our scheme proposes that convergent encryption is applied to the medical cloud, and the hash value of the convergent key is used as a repeat detection label and Bloom filter search to achieve the efficiency of the medical cloud, and the practicality of medical data is improved by introducing fuzzy keywords searching, ensuring the safe storage and correctness of medical data through local validation. At the same time, based on the actual application of different medical data, we use the authorization access method of identity token to realize the multi role access of medical cloud.
