Abstract
An identity authentication method is provided, which relates to the field of artificial intelligence. The method includes: obtaining a biological feature extracted from a first registration object in a registration scenario; obtaining a biological feature extracted from a first recognition object in a recognition scenario; calculating a likelihood score based on the biological feature of the first registration object and the biological feature of the first recognition object; and determining, based on the likelihood score, whether an identity of the first recognition object is consistent with an identity of the first registration object. The likelihood score includes a posterior probability part and a marginal probability part.
