The invention discloses a cloud-computing-based electric power communication security face intelligent identification system, which comprises a cloud computing unit, a cloud storage unit, a data exchange unit, a controller, a display module, a database, an access control module, a face identification module, a data storage unit and a camera shooting module, wherein the camera shooting module comprises a plurality of cameras, and the cameras are arranged outside a communication machine room. The cloud-computing-based electric power communication security face intelligent identification system obtains a verification face image and a verification whole body image by means of the camera shooting module according to relevant rules, then identifies the verification face image by using the face identification module, once the identification is successful, obtains a person name of a corresponding person, marks the verification whole body image as a whole body image to be confirmed, then transmits the whole body image to be confirmed to the cloud computing unit, determines a face portion and a half body portion by means of the cloud computing unit and the cloud storage unit, opens the access control when determining that the one is the person by combining the relevant rules with algorithms, and forms an entry record.
