Embodiment Construction

[0074] The solutions provided in this specification will be described below in conjunction with the accompanying drawings.

[0075] Firstly, in this specification, the data source includes the computing device of the party that owns the data source.

[0076] At least two data sources are involved in the joint prediction business, and each data source has its own private data. For example, data source 1 has the user’s age, weight, gender, etc. data, and data source 2 has the user The data such as educational background, occupation, salary, etc. of the user, the data source 3 has data such as the user's deposit, historical financial management records, etc. If the user applies for a loan, it can jointly calculate and jointly predict the loan risk of the user based on the private data of the three data sources, so as to decide whether to provide a loan to the user.

[0077] In the existing technology, the private data of the three data sources will be aggregated into one decisio...

Abstract

The embodiment of the invention provides a joint prediction method and device. The joint prediction method applied to a data source end comprises the following steps: obtaining a first decision algorithm, wherein the first decision algorithm comprises an attribute judgment method for private data of the data source end; according to the first decision algorithm, carrying out attribute judgment on local private data to obtain local decision information; and providing the local decision-making information to a decision-making party.

Description

technical field [0001] One or more embodiments of this specification relate to electronic information technology, and in particular to a joint prediction method and device. Background technique [0002] In the era of big data, there are many data islands. The data of each user is scattered and stored in different data sources. However, it is necessary to use various data scattered in different data sources to perform joint prediction for users, so as to perform business control according to the result of the joint prediction. [0003] At present, the method of joint forecasting is mainly that each data source aggregates its own data and sends it to a decision-making party, and the decision-making party performs joint forecasting based on the data obtained from each data source. However, this joint prediction method will lead to data leakage, and the security is not high. Therefore, it is desirable to provide a safer joint forecasting method. Contents of the invention ...
