A method for recognizing an identity in a video conference, comprising: obtaining, by an identity recognition apparatus, first biometric feature information in a video conference, wherein the first biometric feature information are biometric feature information of a participant whose identity is to be recognized and comprises at least one of facial feature information and voiceprint feature information; obtaining, by the identity recognition apparatus, second biometric feature information corresponding to an identity list in a database and a conference probability value corresponding to the identity list, wherein the identity list comprises at least one personal unique identifier, the second biometric feature information comprises at least one of facial feature information and voiceprint feature information, and the conference probability value is determined based on a same conference probability value, wherein the same conference probability value indicates a probability that a user participates in a same conference with another user, there is a one-to-one correspondence between the personal unique identifier and the second biometric feature information, and there is a one-to-one correspondence between the personal unique identifier and the conference probability value; and determining, by the identity recognition apparatus, from the identity list and based on the second biometric feature information corresponding to the identity list and the conference probability value corresponding to the identity list, a personal unique identifier corresponding to the first biometric feature information, where at least one of facial feature information and voiceprint feature information in the second biometric feature information corresponding to the determined personal unique identifier is most similar to at least one of facial feature information and voiceprint feature information in the first biometric feature information. obtaining, by an identity recognition apparatus, first biometric feature information in a video conference, wherein the first biometric feature information are biometric feature information of a participant whose identity is to be recognized and comprises at least one of facial feature information and voiceprint feature information; obtaining, by the identity recognition apparatus, second biometric feature information corresponding to an identity list in a database and a conference probability value corresponding to the identity list, wherein the identity list comprises at least one personal unique identifier, the second biometric feature information comprises at least one of facial feature information and voiceprint feature information, and the conference probability value is determined based on a same conference probability value, wherein the same conference probability value indicates a probability that a user participates in a same conference with another user, there is a one-to-one correspondence between the personal unique identifier and the second biometric feature information, and there is a one-to-one correspondence between the personal unique identifier and the conference probability value; and determining, by the identity recognition apparatus, from the identity list and based on the second biometric feature information corresponding to the identity list and the conference probability value corresponding to the identity list, a personal unique identifier corresponding to the first biometric feature information, where at least one of facial feature information and voiceprint feature information in the second biometric feature information corresponding to the determined personal unique identifier is most similar to at least one of facial feature information and voiceprint feature information in the first biometric feature information.
