Embodiment 1

[0040] An embodiment of the present invention provides a method for de-identifying diagnosis and treatment data. The method for de-identifying diagnosis and treatment data includes:

[0041] S101, constructing a diagnosis and treatment data query database according to the pre-retrieved diagnosis and treatment data; the diagnosis and treatment data include basic patient information and diagnostic information corresponding to the basic patient information, imaging information, etc.;

[0042] S102, according to the differential privacy algorithm, adding random noise to the sensitive attribute field of the data table of the diagnosis and treatment data query database;

[0043] S103. De-identify the sensitive attribute field according to the added random noise;

[0044] S104. Encrypt the identifier field of the data table; wherein, the sensitive attribute is the attribute set of private data including: patient gender, age, education level, region, examination equipment type, diseas...

Embodiment 2

[0092] An embodiment of the present invention provides a diagnosis and treatment data de-identification device, the diagnosis and treatment data de-identification device includes: a memory, a processor, and a computer program stored in the memory and operable on the processor;

[0093] When the computer program is executed by the processor, the steps of the method for de-identifying medical data as described in any one of the first embodiment are realized.

Embodiment 3

[0095] An embodiment of the present invention provides a computer-readable storage medium. The computer-readable storage medium stores a diagnosis and treatment data de-identification program. When the diagnosis and treatment data de-identification program is executed by a processor, the implementation as in Embodiment 1 Steps in any one of the methods for de-identifying medical data.

Abstract

The invention relates to a diagnosis and treatment data de-identification method and device and a query system. The diagnosis and treatment data de-identification method comprises the following steps: constructing a diagnosis and treatment data query database according to pre-called diagnosis and treatment data; according to a differential privacy algorithm, adding random noise to a sensitive attribute field of a data table of the diagnosis and treatment data query database; carrying out identification removal processing on the sensitive attribute field according to the added random noise; performing encryption processing on an identifier field of the data table; and updating the diagnosis and treatment data query database according to the data table subjected to identification removal processing and encryption processing. According to the method, the confidentiality requirement of differential privacy protection of the diagnosis and treatment data is met, meanwhile, the reliability of data published in the database is ensured, clinical scientific researchers can be effectively helped to query and collect previous cases and analyze and evaluate big data, and the method and the system are provided for promoting automation of medical data statistics and eliminating information islands. And a good foundation is laid for decision support establishment.

Description

technical field [0001] The invention relates to the technical field of medical data processing, in particular to a method, device and query system for de-identifying medical data. Background technique [0002] Medical big data security has become a major problem in hospital management in the era of big data, and various data leakage incidents occur from time to time. At present, the security protection of medical big data usually adopts the methods of anonymizing and desensitizing the important information of patient examination. However, a purposeful attacker can still locate the locked object through several composite known condition queries. If there are too many desensitized fields, the value of scientific research will be lost. For example, if the gender, age, region, examination site, and disease fields are directly desensitized, then it is impossible to conduct research on the subject of "incidence of lung diseases in various regions, age groups, and genders".
