Abstract: Mismatched drivers may be identified based on passenger evaluations. A set of evaluations may be obtained. Each evaluation in the set of evaluations may be based on whether a current driver matches a registered driver. A convergence point number may be obtained. The convergence point number may be a number of evaluations required for accurate identification. An identification rate may be computed based on the set of evaluations and the convergence point number. The current driver may be verified based on a comparison of the identification rate to a threshold match rate. If the identification rate is greater than a threshold match rate, it may be determined that the identity of the current driver is valid. If the identification rate is not greater than a threshold match rate, the current driver may be identified as a mismatched driver.
