| 英文摘要 | Hospitals are gradually adopting EHR methods to record patients' medical information. However, the privacy of medical data and the differentiation of EHR standards hinder the sharing of medical data between patients and hospitals. Therefore, for the problem of leakage of private information and difficulty in sharing, this paper proposed a privacy protection data-sharing model based on the consortium blockchain. In addition, based on the anonymous algorithm, it proposed the(<i>p</i>, <i>α</i>, <i>k</i>) anonymous privacy algorithm, which could solve the problem of HER private information leakage. Through theoretical analysis and experimental results, the proposed consortium-based chain and(<i>p</i>, <i>α</i>, <i>k</i>) privacy anonymity algorithm model can realize data security sharing between patients and hospitals under the premise of protecting data privacy. Compared with the previous models, the proposed model has the advantages of fewer nodes, less main chain pressure, better fault tolerance and complete control of the patient's HER. |
