Patent number: 11271931Abstract: Techniques for securely generating and using a “fingerprint” for authentication. A server computer receives a first data set from a user device (including a first fuzzy hash of first user data on the user device). The server computer generates a first fingerprint value based on the first data set. The server computer detects an event corresponding to a user in association with the user device. The server computer identifies a baseline fingerprint value (generated based on a baseline fuzzy hash of user data on the user device). The server computer compares the first fingerprint value to the baseline fingerprint value to generate a similarity score. The server computer may determine that the similarity score exceeds a threshold value but does not represent an exact match, and, based on the similarity score, authenticate the user and update the baseline fingerprint value based on the first fingerprint value.Type: GrantFiled: September 19, 2019Date of Patent: March 8, 2022Assignee: Visa International Service AssociationInventors: Vinjith Nagaraja, Nagaveera Venkata Su Tavvala, Jose Rios Trevino, Vamshi Ramarapu, Swapneel Mahajan, Joel Trunick, Shalini Mayor, James Myers, Raymond Brammer, Ireneusz Pazdzierniak, Shashi Velur, Feng Chi Wang, Vincent Hesener
