[0002] Existing friend recommendation systems generally make recommendations based on the degree of connection between friends who are similar to friends. Although they can meet the needs of most friends, they are similar to cold start (cold start means that a new user has just joined system, not associated with anyone, and there is no relevant information about the new user in the system), the existing system cannot effectively solve
At the same time, if an attacker can establish a connection with a certain user by forging an account, the existing system will recommend the user's friends to the attacker at this time, thereby leaking the user's social relationship and allowing the attacker to obtain a large amount of information. There is a very high probability of leaking user privacy

The embodiment of the invention provides an associated user recommendation method and device, and the method is used for recommending an associated user to a target user. The method comprises: acquiring a first user group, the first user group comprises a plurality of first users, and contact information of a target user is stored in a contact information base of each first user; enabling each first user to be corresponding to one user node; determining a node relation value corresponding to each user node, wherein the node relation value is used for representing the contact tightness degree between the user node and a target user; and selecting at least a part of user nodes as associated users to recommend to the target user according to the node relation value.
Description
technical field [0001] The present disclosure relates to the field of computer technology, and in particular to a method and device for recommending associated users. Background technique [0002] Existing friend recommendation systems generally make recommendations based on the degree of connection between friends who are similar to friends. Although they can meet the needs of most friends, they are similar to cold start (cold start means that a new user has just joined system, is not associated with anyone, and there is no relevant information about the new user in the system), the existing system cannot effectively solve it. At the same time, if an attacker can establish a connection with a certain user by forging an account, the existing system will recommend the user's friends to the attacker at this time, thereby leaking the user's social relationship and allowing the attacker to obtain a large amount of information. There is a very high probability of leaking user pr...
