Abstract

The invention discloses a sensitive information processing method. The method comprises the following steps: exchanging and encrypting data sets of the first terminal and the second terminal accordingto an exchangeable encryption algorithm; obtaining a first encryption set of the first terminal and a second encryption set of the second terminal, according to the first prediction model, a data setowned by the first terminal and a homomorphic encryption algorithm, obtaining prediction data encryption set, obtaining intersection data encryption set of the first encryption set and the second encryption set, and acquiring prediction data encryption set of intersection data encryption set, and sending the intersection data encryption set and prediction data encryption set of the intersection data encryption set to the second terminal, so that the second terminal obtains a target prediction set corresponding to the intersection data set. The invention further discloses equipment and a readable storage medium. The multi-model joint prediction value corresponding to the intersection data can be obtained without disclosing respective data sets between the terminals, so that the data privacy is protected, and the information security is improved.

Description

technical field [0001] The present invention relates to the technical field of machine learning, in particular to a sensitive information processing method, device and readable storage medium. Background technique [0002] In highly professional fields, such as medical care, finance, etc., high-quality evaluation models are often scattered in different corporate organizations. For example, evaluation models can be used to evaluate post-loan risks. Enterprises will have the same customers. For evaluation, you can use the models owned by each enterprise organization to make predictions, and then make further statistics on the prediction results given by each enterprise. The existing practice is usually to set up party A and party B, and party B needs to request forecast data from party A. This process involves party B needing to pass its own customer information to party A, and party A based on the received customer information Information acquires characteristic data and mod...
