Embodiment Construction

[0032] The specific embodiments of the invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0033] figure 1 It shows a schematic flowchart of a big data privacy processing method provided in this embodiment, including:

[0034] S1. Process the big data in the original file according to the data segmentation algorithm to obtain private data;

[0035] S2. Acquiring the location information of the private data in the original file, establishing a mapping table between the private data and the original file according to the private data and the location information, and establishing an index table according to the original file and the mapping table, At the same time, the mapping table and the index table are stored in a relational database.

[0036] It can be seen f...

Abstract

The present invention discloses a large data privacy processing method and apparatus. The method comprises: processing large data in an original file by using a data segmentation algorithm, and obtaining privacy data; and obtaining location information of the privacy data in the original file, establishing a mapping table of the privacy data and the original file according to the privacy data and the location information, establishing an index table of the original and the mapping table. According to the method disclosed by the present invention, the privacy data is segmented from the large data by using the data segmentation algorithm, the privacy data is solely stored through a single relationship database, the problem of privacy data leakage easily caused by common storage and processing of the privacy data and non-privacy data by the large data in current cloud environment can be solved, thereby playing a promotion role in further development of medical data security.

Description

technical field [0001] The invention relates to the field of information security, in particular to a big data privacy processing method and device. Background technique [0002] At present, the rapid development of medical big data has brought great convenience to residents' health and medical research, and it is convenient for residents to search and consult relevant data. However, since medical big data involves a lot of personal privacy data, these personal privacy data need specific data protection, especially in an open cloud environment, it is more necessary to carry out privacy processing on big data. However, the current medical big data in the cloud environment does not separately protect and process personal privacy data. How to protect the personal privacy of medical big data in the cloud environment has become an urgent problem to be solved. Contents of the invention [0003] Since private data and non-private data are stored and processed together in the cur...
