Embodiment Construction

[0060] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts belong to the protection scope of the present invention.

[0061] refer to Figure 1-2 , the present invention provides a medical cloud storage public audit method based on block chain technology that can anonymize identity:

[0062] Such as figure 1 As shown, the public audit method of medical cloud storage based on blockchain technology with anonymous identity includes outsourcing medical data integrity verification steps and third-party auditor TPA behavior verification steps.

[0063] The steps of verifying the integrity of the outsourced medical data include:

[0064] S1. Initiali...

Abstract

The invention discloses a medical cloud storage public auditing method of anonymous identity based on the blockchain technology. The method comprises an outsourcing medical data integrity verificationstep and a third party auditor behavior checking step, wherein the outsourcing medical data integrity verification step comprises an initialization sub-step, an anonymous identity and signature private key generation sub-step, a digital signature generation sub-step and an outsourcing medical data auditing sub-step, and the third party auditor behavior checking step comprises an auditing log filegeneration sub-step and an auditing log file inspection sub-step. In the medical cloud storage public auditing method disclosed by the invention, a user sends the real identity to a key generation center to obtain the corresponding anonymous identity, thereby ensuring the identity privacy of the user, and a third party auditor periodically challenges-verifies the integrity of the outsourcing medical data stored by the user on a cloud server and defends a data linear recovery attack of an auditor by using the random mask technology.

Description

technical field [0001] The invention relates to the technical field of cyberspace security, in particular to a public audit method for medical cloud storage based on block chain technology that can anonymize identities. Background technique [0002] Nowadays, with the acceleration of the aging process and the increase in the demand for health care services, wireless body area networks have become more and more important. Wireless body area networks rely on a variety of medical sensor devices and wireless communication technologies to collect medical health data and remotely monitor patients' health conditions anytime, anywhere, and place medical sensors with limited storage and computing capabilities on the patient's body surface or embed them Its epidermis regularly collects various healthy physiological characteristics, such as blood pressure, blood sugar, heart rate, etc., but these important medical data need to be processed in real time, and patients need to obtain feed...
