1. An identity authentication method, executed by a computer device, the method comprising:
acquiring a raw feature of a user, the raw feature containing m−1 domain discrepancy features, and m being an integer greater than 2;
extracting a primary attribute feature vector in the raw feature by:
transforming, by a basic generator, the raw feature into a global attribute feature vector; and
performing feature extraction, by a primary generator, on the global attribute feature vector to obtain the primary attribute feature vector, the primary attribute feature vector being an unbiased feature representation by selectively decoupling the m−1 domain discrepancy features in the raw feature; and
performing unbiased identity authentication based on the primary attribute feature vector to obtain an identity authentication result by a step comprising performing the identity authentication, by a primary discriminator, on the primary attribute feature vector to obtain the identity authentication result or performing first discrimination, by the primary discriminator, on the primary attribute feature vector to provide a combined attribute feature vector.
