Abstract

The embodiment of the invention provides an object recommendation method, device and system based on a block chain, and the method is applied to a node device in a block chain network, and comprises the steps: receiving a recommendation request for a target object sent by a client; in response to the recommendation request, calling an intelligent contract, and performing privacy data processing on user privacy data submitted by each data platform to obtain a user feature set; and sending the user feature set to the client, so that the client screens out a target user according to the user feature set, and recommends a target object to the target user. Through the method, the user feature set can be more accurately generated while the security of the user privacy data is ensured, so that the client can recommend the target object to the target user in a more targeted manner.

Description

technical field [0001] The embodiments of this specification relate to the field of computer technology, and in particular, to a method for recommending objects based on blockchain. Background technique [0002] With the development of Internet technology, various network platforms will send various recommended information to users according to their needs to meet the individual needs of different users. [0003] At present, each network platform sends personalized recommendation information to users based on the user data of their respective platforms. For platforms with a lack of user data, it is impossible to send accurate recommendation information to users; and the user data of each platform involves user privacy and It is a commercial secret, and multiple platforms cannot directly share user data to accurately send personalized recommendation information to users. [0004] Therefore, how to accurately send personalized recommendation information to users is an urgent ...
