A method and an apparatus for integrating information are provided in the embodiment of that present invention. The method comprises the following steps: when detecting that an object to be recognizedenters a preset recognition area, controlling the start-up camera to collect a face image of the object to be recognized, and obtaining the identity information of the object to be recognized from the ID card reader; when the object to be recognized enters a preset recognition area, controlling the start-up camera to collect a face image of the object to be recognized; comparing the face image with the face in the identity information; if the comparison result is consistent, collecting the iris image of the object to be recognized by the camera; correlating and integrating the iris image, theface image and identity information. At the time of detecting that the object to be identified enter the preset identification area, the camera is started to acquire the face image, and ID card information is acquired through the ID card reader, and the iris image is acquired at that same time, so the acquisition, verification and integration of identity information are automatically completed, which is conducive to realizing automatic acquisition and information integration of iris information of large-scale crowd.
