Claim of US Patent No. 10,462,257

1. A method for obtaining a user account, comprising:obtaining user information of a plurality of to-be-analyzed user accounts registered with a website or application;
identifying a real-name account from the to-be-analyzed user accounts according to the user information of the to-be-analyzed user accounts, comprising:
determining, for a user account of the to-be-analyzed user accounts, whether user information of the user account comprises specified user information, the specified information including at least one of: user human-face data from an identity verification image of the user account, a user signature added by the user account or by a friend account of the user account, and personal presentation information extracted from a plurality of photos uploaded by the user account with same person appearance; and
identifying the user account as a real-name account when the user information of the user account comprises the specified user information; and
determining a first anonymous account similar to the real-name account according to at least two of a login time, login device information, and user usage habits of the real-name account, the first anonymous account being one of the to-be-analyzed user accounts registered with the same website or application that does not comprise any one of the user human-face data, the user signature or the personal presentation information;
establishing a mapping relationship between the specified user information, the real-name account, and the first anonymous account; and
in response to a user management request corresponding to the first anonymous account, locating the real-name account and the specified user information based on the mapping relationship,
wherein determining the first anonymous account similar to the real-name account comprises:
generating an eigenvector of the real-name account based on a vector conversion manner according to the login time, the user usage habits, and the login device information of the real-name account;
generating eigenvectors of all anonymous accounts in the to-be-analyzed user accounts based on the same vector conversion manner, wherein each anonymous account is one of the to-be-analyzed user accounts that does not comprise any specified user information;
obtaining similarity degrees between the eigenvector of the real-name account and the eigenvectors of the anonymous accounts; and
determining an anonymous account having a corresponding similarity degree greater than a preset threshold as the first anonymous account similar to the real-name account.
