A method for recognizing an identity of a human target, comprising: obtaining a to-be-recognized image acquired by an image acquisition device in communication with a server; extracting a target feature of a to-be-recognized human target in the to-be-recognized image as a to-be-searched target feature, wherein the target feature includes color, texture, size, wearing features, physical features such as a height and body shape of the human target; searching for a facial information item corresponding to the to-be-searched target feature based on a pre-established correspondence between target features and facial information items; wherein, in the correspondence, a pair of a target feature and a corresponding facial information item belongs to a same human target; wherein the facial information items include facial features and a facial image; wherein images from which target features in the correspondence and the corresponding facial information items are extracted comprise a front face of the same human target and are captured by another acquisition device in communication with the same server; and determining an identity of the to-be-recognized human target based on the found facial information item, wherein a pre-established correspondence between facial information items and identities is pre-stored, and wherein, after obtaining a to-be-recognized image, the method further comprises: determining an acquisition attribute of the to-be-recognized image as a to-be-searched acquisition attribute; wherein, the acquisition attribute includes a moment and/or a location at which the to-be-recognized image is acquired; wherein, searching for a facial information item corresponding to the to-be-searched target feature based on a pre-established correspondence between target features and facial information items comprises: searching, in the pre-established correspondence between target features and facial information items, for a target acquisition attribute whose difference from the to-be-searched acquisition attribute is less than a preset threshold; and searching, in facial information items corresponding to the target acquisition attribute, for a facial information item corresponding to the to-be-searched target feature. obtaining a to-be-recognized image acquired by an image acquisition device in communication with a server;
