Device fingerprint processing method and device of mobile device, server, and storage medium

The invention discloses a device fingerprint processing method and device of a mobile device, a server, and a storage medium. The device fingerprint processing method includes: performing merging processing on device basic information and device detection information of a mobile device to be queried, and acquiring device complete information of the mobile device to be queried; constructing a data key according to the device complete information, and querying a data value corresponding to the data key in a buffer; determining if the acquired data value corresponding to the data key is empty or not; assigning a device fingerprint contained in the data value to the mobile device to be queried if the data value is not empty; constructing a query statement corresponding to the device complete information if the data value is empty, and using the query statement to perform query in the database to acquire a query result set; and determining the device fingerprint of the mobile device to be queried according to the
