Abstract: Fingerprints of file node(s) within a first data tree and file node(s) within a second data tree may be generated. The first data tree may include a first set of directory nodes and a first set of file nodes. The second data tree may include a second set of directory nodes and a second set of file nodes. A delta between the first data tree and the second data tree may be generated based on a first classification of similarity between the first set of file nodes and the second set of file nodes, a second classification of similarity between the first set of directory nodes and the second set of directory nodes, and file-node delta(s) between file node(s) of the first set of file nodes and file node(s) of the second set of file nodes. The file-node delta(s) determined based on two or more of the fingerprints.

Abstract: Aspects of the invention are directed to techniques for mutual authentication between a passenger that has requested a transportation service and a dispatched vehicle for providing the requested transportation service. A user device associated with the passenger verifies the dispatched vehicle using a vehicle access token generated by a transportation service platform and sends a secret key to the dispatched vehicle. The dispatched vehicle uses the secret key to recover passenger biometric information from a passenger secret received from the user device through the transportation service platform, captures passenger biometric information on-site, and compares the recovered passenger biometric information and the passenger biometric information collected on-site to verify the passenger.
