Problems solved by technology
Although this method is simple and easy to implement, in actual business, the query requester often does not want his large number of query requests to be used by the data source to deduce the purpose of the query and the use of the data. This bilateral relationship between the data source and the data query party The business model has great limitations and is suitable for internal queries of business systems, not for inter-system queries that lack trust relationships

Embodiment Construction
[0031] In order to describe the technical content of the present invention more clearly, further description will be given below in conjunction with specific embodiments.
[0032] The method for realizing information query based on the de-identification of the data object subject of the present invention includes the following steps:
[0033] (1) The data query party generates an exclusive tag idA with the de-identification of the query data subject, and the public key PKey_A of the query party, and sends a query request to a trusted third party;
[0034] (2) The trusted service third party generates the serial number of the query business;
[0035] (3) The trusted service third party obtains the exclusive mark, and sends the query business serial number, the exclusive mark and the public key PKey_A of the querying party to the data source;
[0036] (4) The data source queries through the exclusive mark, and encrypts the query result with the public key PKey_A of the querying...

The invention relates to a method for realizing information query based on data object main body deidentification, which comprises the following steps: a data query party generates an exclusive mark idA with query data main body deidentification and a query party public key PKey _ A, forms a query request and sends the query request to a trusted service third party; the trusted service third partygenerates a current query service serial number; the trusted service third party obtains the exclusive mark, and sends the query service serial number, the exclusive mark and the query party public key PKey _ A to the data source; the data source is queried and encrypted through the exclusive mark, and a trusted service third-party service serial number is returned by the data source; and the trusted service third party returns the query party exclusive mark idA corresponding to the serial number and a result encrypted by the query party public key PKey _ A returned by the data source to thequery party. By adopting the method for realizing information query based on data object main body deidentification, query requests seen from one side of a data source are all from a trusted service third party and cannot know which query party performs query, a query result is encrypted by the data source by using a public key of the query party, and the trusted service third party cannot view the query result.
Description
technical field [0001] The present invention relates to the field of data information security, in particular to the cross-technical field of data sharing and information security, and specifically refers to a method for realizing information query based on the de-identification of data object subjects. Background technique [0002] With the rapid development of information technology and big data applications, the types and quantities of data in all walks of life are increasing exponentially. More and more people realize the value of data and realize the great significance of data openness and sharing. However, the open sharing of data also brings about the issue of personal information security protection. The data collected by government agencies, enterprises, and other organizations usually contains information such as personal names, phone numbers, and ID numbers. If the collected raw data is directly released, it will lead to serious personal information leakage. How ...
