Method for authenticating identity of registrant, server, equipment and storage medium

The invention relates to the field of databases, and provides a registrant identity authentication method, a server, equipment and a storage medium. The method comprises the steps: extracting and storing a first group of data corresponding to a first group of identifiers from a third-party data source if the third-party data source called according to the first group of the identifiers carried bya first registration request of a first user terminal carries out third-party authentication on a group to which a user belongs; matching a second group of identifiers carried in a received second registration request of a second user terminal with a white list; if the second group of the identifiers are matched with the group identifier in the white list, or if the similarity between the second user identifier and the first user identifier is greater than a preset similarity, determining that the group to which the second user belongs is a historical authentication group; and if the second registration request passes
