Information recommendation method and device, server and storage medium

Abstract

Embodiments of the present application provide an information recommendation method and device, a server and a storage medium. In the method, a business server obtains an encryption policy result of each to-be-processed user according to a policy processing request, a target user representation set and encrypted behavior feature information of an associated user sent by a merchant server, and then returns the encryption policy result to the merchant server. When it is detected that a to-be-recommended user is in a recommendation scenario, the to-be-recommended user is recommended information according to the policy result corresponding to the to-be-recommended user obtained from the merchant server. The technical solution uses rich user association information in the business server and uses behavior feature information of the user in the merchant server, avoids user plaintext data export and leakage, solves the data island problem and ensures data compliance, can mine user hidden consumption potential on the premise of ensuring data security, and improves information recommendation accuracy.
