Abstract

The invention provides a big data access authorization method and device and a big data platform. The method comprises the following steps: extracting behavior information of an authenticated user ofthe big data platform; evaluating the behavior information of the user according to the service scene, marking user tags of multiple dimensions a for the user to construct a user portrait, and acquiring the tag weight corresponding to each user tag by fusing the subjective importance degree and the objective importance degree of the tags; updating the user portrait at preset time intervals to realize dynamic updating of the user tag and the tag weight thereof; and performing access authorization on the user according to the updated user portrait. According to the invention, personalized authorization of different users can be realized, and the constantly changing personalized access requirements of different subjects are met. Dependence on professional knowledge of an administrator can bereduced, and the administrator can actively authorize a user in advance conveniently. The user rsuspicion and the service demand can be accurately predicted and the data security of the big data platform can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of data platforms, in particular to a big data access authorization method, a big data access authorization device and a big data platform. Background technique [0002] The advent of the big data era has made data an important economic asset. For example, Apache Hadoop, with its excellent data storage capabilities and distributed computing advantages, has become the main platform for processing large amounts of data. However, Hadoop was originally developed around how to manage a large amount of public Web data, lacking data confidentiality and internal complex authority management considerations. However, the data collected from different enterprises, organizations or institutions stored on the Hadoop platform often contains private and sensitive information, and the big data platform is faced with many access subjects, it is difficult to ensure that these information are protected from unauthorized access...
