Embodiment Construction

[0020] Such as figure 1 As shown, an anonymous and untraceable online medical treatment method includes the following steps:

[0021] Step 1: System Initialization

[0022] The trusted center generates two cyclic groups G of order q 1 ,G 2 , bilinear map e:G 1 *G 1 →G 2 , P is G 1 generator, and then randomly select ( Represents an integer from 1 to q-1) as the master key, and then calculates the master public key P pub = sP, and two secure collision-free cryptographic hash functions H 1 (.):{0,1} * →G 1 , The trusted center publishes system parameters {G 1 ,G 2 ,e,q,P,P pub ,H 1 (.),H 2 (.)}, and then keep the master key s secret.

[0023] Step 2: Registration Phase

[0024] The first is the registration of doctors, Doctor D l Submit identity information id dl To the trusted center, the trusted center first verifies whether the identity information submitted by the doctor is valid, and if the information is valid, calculates the first public key Q of t...

Abstract

The invention discloses an anonymous and untraceable online health information acquisition method. According to the method, system parameters are generated by a trusted center; the doctor registers identity information iddl, and the trusted center sends the first public key and the first private key to the doctor through a secure channel; the patient registers identity information idPTi, the trusted center selects non-linkable pseudo-random identity information pidj for the patient, and a corresponding second public key set and a second private key set are obtained; the patient selects effective pseudo identity information and a corresponding second private key, calculates a session key, generates a first ciphertext C1 and a signature sigma PTi by using the session key, and sends {TPTi-new, sigma PTi, C1, pidj, iddl} to the trusted center; the trusted center carries out effective verification on the received information, and then sends {TPTi-new, sigma PTi, C1, pidj, iddl} to a corresponding doctor; the doctor performs analysis and diagnosis after decryption; the doctor feeds back the authentication information and the second ciphertext C2 to the patient; and after the patient verifies the information, decrypting to obtain a health result. The beneficial effect of the invention is that confidentiality, anonymity and untrackability of health information are provided for patients.

Description

technical field [0001] The invention belongs to the field of information security technology and online health consultation, and in particular relates to an anonymous and untraceable online health information acquisition method. Background technique [0002] eHealth has become a new industry. "Electronic health" refers to electronic health information and services obtained through Internet technology, mobile media and other channels. These services allow patients to use the Internet, such as health support through blogs, forums, online communities, doctor-patient communication systems, and other advanced systems. There are more than 5,000 healthcare-related apps or software around the world. Online health counseling is one of the most popular and rapidly growing online health services. The number of online consulting users continues to grow. There are more than 250,000 health consultations in China every month. [0003] However, a large amount of sensitive health data n...
