  • Method, apparatus and device for generating device fingerprint and storage medium
    Patent number: 12355764
    Abstract: Embodiments of this application disclose a method for generating a device fingerprint and a relevant apparatus. The method includes: obtaining a plurality of device features of a target device; obtaining, based on the plurality of device features, a target device feature group of the target device by combining different device features of the target device; querying an inventoried device fingerprint library to retrieve candidate device features of at least one candidate inventoried device mapped to the target device feature group; identifying a device similarity, to obtain a similarity between the target device and the at least one candidate inventoried device; and in response to the similarity between the target device and the at least one candidate inventoried device being greater than a similarity threshold, using a device fingerprint of the at least one candidate inventoried device as a device fingerprint of the target device.
