Patent ID: 11882147
Assignee: LYFT, INC.
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 8:
9. A system comprising:
at least one processor; and
at least one non-transitory computer-readable storage medium storing instructions that, when executed by the at least one processor, cause the system to:
receive a digital request from an unknown requestor device to perform a network action;
send a query associated with the unknown requestor device to one or more computing devices among a trusted network of computing devices;
generate a dynamic risk graph model associated with the digital request based on a digital response to the query from the one or more computing devices;
update the dynamic risk graph model utilizing a time-decay function by:
assigning the digital request to a risk category;
mapping the risk category to a risk category probability; and
applying the time-decay function to the risk category probability;

generate a trust score for the digital request to perform the network action by analyzing the updated dynamic risk graph model; and
based on the trust score, provide an indication to the one or more computing devices among the trusted network of computing devices to allow the unknown requestor device to perform the network action.
