As shown in FIG. 1, the apparatus for identifying license plate tampering shown may further comprise a third identifier 5. The image obtainer 1 is further configured to send the license plate number image to the third identifier 5. The third identifier 5 is configured to determine whether the license plate is blocked according to the license plate number image, and send a second identification command to the second identifier 3 when the license plate of the vehicle is determined to be not blocked. The second identifier 3 is further configured to determine whether the vehicle information contained in the vehicle image is consistent with the standard vehicle information in the vehicle information base after receiving the second identification command. In an exemplary embodiment of the disclosure, the third identifier may be implemented as a DSP chip or an embedded chip. However, the third identifier of the disclosure is not limited thereto, but may also be any other device or determining circuit that can determine whether the license plate of the vehicle is blocked.
