摘要： A method for granting access for a user to a domain which is subject to an access restriction, wherein the user belongs to a group of one or more user shaving an access privilege in relation to the domain. The method comprises acquiring a first set of biometric data associated with the user. A first identification is successful if a comparison of the first set of biometric data to previously acquired data relating to the user, or to the group of users, indicates that the user belongs to the group. The method also comprises acquiring a second set of biometric data associated with the user responsive to the first identification being successful. A second identification is successful if a comparison of the second set of biometric data to previously acquired data relating to the user indicates that the user has the access privilege.

摘要： A method of controlling operation of a field-powered biometric device comprising biometric acquisition circuitry, processing circuitry controllable to transition between a first functional state having a first power consumption and a second functional state having a second power consumption lower than the first power consumption, and power management circuitry. The method comprises the steps of monitoring, by the power management circuitry, a property indicative of a supply voltage to the processing circuitry; controlling, when the monitored property indicates that the supply voltage has fallen to a first threshold voltage, the processing circuitry to transition from the first functional state to the second functional state; and controlling, when the monitored property indicates that the supply voltage has increased to a second threshold voltage higher than the first threshold voltage, the processing circuitry to transition from the second functional state to the first functional state.
