Abstract: A method for peer validation for unauthorized transactions includes receiving a request to validate a user performing a transaction anomaly, wherein the transaction anomaly represents a potential fraudulent financial transaction. The method, responsive to identifying one or more boundaries to search for validation users, identifies a set of validation users in the identified one or more boundaries, where each validation user from the set of validation users has the ability to visually confirm the user performing the transaction as a valid user associated with an account for the transaction anomaly. The method displays information for the valid user associated with the account for the transaction anomaly. The method, responsive to determining the user is not validated for the transaction anomaly, declines the transaction anomaly.

Abstract: A starter battery with a total battery voltage exceeding a supply voltage requirement of an electrical system. An alternator provides a charging voltage that corresponds with the supply voltage requirement of the electrical system. A total battery voltage equal to the sum of cell voltages exceeds the supply voltage requirement of the electrical system. A step-down voltage regulator reduces the total battery voltage to correspond with the supply voltage requirement and a boost voltage regulator increases the charging voltage from the alternator when charging the starter battery to the total battery voltage. When detecting a degraded cell, the step-down voltage regulator continues to regulate the total battery voltage to correspond with the supply voltage requirement after the cell has degraded and the boost voltage regulator is bypassed when charging the starter battery to no longer increase the charging voltage from the alternator when charging the starter battery.

The method further includes transmitting, by the host processing system, the single use authentication map to a user processing system that presents an authentication interface comprising the public set of characters to enable a user to enter a user passcode using the public set of characters. The user processing system encodes the user passcode into a single use passcode using the single use authentication map. The method further includes the host processing system receiving the single use passcode from the user processing system, decoding the single use passcode back the user passcode using the single use authentication map, and determining whether the user passcode matches an expected passcode.
