Abstract
A method for determining a behavior of a smart card, which may be implemented by a server. The method includes operations for obtaining a first reference time data corresponding to a time for setting a smart card clock, and a second reference time data corresponding to a time for reading a first time data from the clock, determining a time drift associated with the smart card based on the first reference time data and on the second reference time data, and determining a behavior of the smart card from the time drift.
