Automatic reset for time-based credentials on a mobile device

摘要

Embodiments of the present disclosure may provide methods and devices capable of synchronizing time between a credential device and an authentication service. In an embodiment, a change in a time value on a device may be detected. A time value may be retrieved from an authentication service, and a new time value generated based upon at least the time value retrieved from the authentication service. The new time value may be used to set a time value at the device, and/or to generate a time-based credential.

1. A method of synchronizing time between a device and an authentication service, the method comprising:
detecting, by an event handler executing on a processor on the device, a change in a time value on the device on a periodic basis and the periodic basis is set to reduce a battery drain of the device, wherein: the detecting comprises capturing an adjustment to the time value on the device through a callback to the event handler when the change in the time value occurs; accumulating a plurality of time changes to the time value on the device; determining a total time difference based on the plurality of time changes to the time value on the device; determining that the total time difference exceeds a credential mismatch time value; and retrieving, by the processor, a time value from an authentication service when the total time difference in the time value on the device exceeds the credential mismatch time value; generating, by the processor, a new time value based on at least the time value retrieved from the authentication service; and generating, by a software-based credential application executing by the processor, a time-based credential based on the new time value.
