Method, apparatus and system for measuring finger moisture

An apparatus for measuring finger moisture, comprising a processor and a memory storing instructions thereon, the processor when executing the instructions, being configured to:

• obtain a fingerprint image;
• obtain a fingerprint signal intensity and an image background intensity according to the fingerprint image,
• determine the finger moisture according to the fingerprint signal intensity and the image background intensity, identify a user according to the fingerprint image;
• if the user is successfully identified, store data of the finger moisture in a predefined database and determine a health condition of each user according to the data of the finger moisture of the user stored in the predefined database.

A system for measuring finger moisture, comprising:

• an optical imaging collector, a processor communicatively connected with the optical imaging collector and a memory;
• the optical imaging collector is configured to:
• collect a fingerprint image, and send the collected fingerprint image to the processor;
• the processor is configured to:
• obtain the fingerprint image;
• obtain a fingerprint signal intensity and an image background intensity according to the fingerprint image;
