医疗保健已经成为人们生活中不可或缺的一部分，医疗数据量急剧增加（例如，诊断证明和病历）。然而，医疗数据很容易被盗、篡改，甚至完全删除。如果发生上述情况，医疗数据将无法可靠地记录或检索，导致治疗进度延误，甚至危及患者的生命。在本文中，我们提出了一种新的基于区块链的医疗数据保存系统（DPS）。为了提供可靠的存储解决方案，以确保存储数据的可靠性和可验证性，同时保护用户的隐私，我们利用区块链框架。使用建议的DPS，用户可以永久保存重要数据，并且如果怀疑篡改，可以验证数据的原始性。此外，我们使用谨慎的数据存储策略和各种加密算法来保证用户隐私;例如，即使数据被盗，对手也不能读取明文。我们基于真实的世界区块链平台以太坊实现了DPS的原型。性能评估结果表明，所提出的系统的有效性和效率。
Medical care has become an indispensable part of people's lives, with a dramatic increase in the volume of medical data (e.g., diagnosis certificates and medical records). Medical data, however, is easily stolen, tampered with, or even completely deleted. If the above occurs, medical data cannot be recorded or retrieved in a reliable manner, resulting in delay treatment progress, even endanger the patient's life. In this paper, we propose a novel blockchain-based data preservation system (DPS) for medical data. To provide a reliable storage solution to ensure the primitiveness and verifiability of stored data while preserving privacy for users, we leverage the blockchain framework. With the proposed DPS, users can preserve important data in perpetuity, and the originality of the data can be verified if tampering is suspected. In addition, we use prudent data storage strategies and a variety of cryptographic algorithms to guarantee user privacy; e.g., an adversary is unable to read the plain text even if the data are stolen. We implement a prototype of the DPS based on the real world blockchain-based platform Ethereum. Performance evaluation results demonstrate the effectiveness and efficiency of the proposed system.
