The application discloses a method, an apparatus and a system for measuring finger moisture. The method includes: obtaining a fingerprint image； obtain a signal intensity and an image background intensity according to the fingerprint image； and determining finger moisture according to the fingerprint signal intensity and the image background intensity. In the method, apparatus and system for measuring finger moisture provided by the present invention, the fingerprint image is obtained and the fingerprint signal intensity and the image background intensity are obtained based on the fingerprint image, and the finger moisture is determined by analyzing the fingerprint signal intensity and the image background intensity, thereby effectively overcoming the defects in prior art in comparing and analyzing of images, including being prone to be disturbed by undulation of the image background, noise, etc., and low accuracy, thus ensuring the accuracy and reliability of the measurement of the finger moisture.
