An improved technique involves sending a user's authentication information to a local authentication device that computes a risk score and sends the risk score to a remote authentication server that determines whether the user is able to be authenticated. When the user makes an authentication or transaction request from an electronic device such as a computer or smartphone, the electronic device sends predictor values such as geo location and wireless signal strength to the local authentication device. The local authentication device then computes a risk score based on the received predictor values and historical predictor values. The local authentication device sends this risk score to a remote authentication server which determines from this risk score and other factors whether the user is able to be authenticated.

Localized risk analytics for user authentication

An apparatus comprises a processing device comprising a near field communication (NFC) network interface, a memory and a processor coupled to a memory. The processing device is configured under control of the processor to connect to a host device using the NFC network interface, receive an authentication request from another device through the NFC connection with the host device and authenticate the other device using information stored in the memory. A passcode is presented to the host device responsive to a successful authentication of the other device, the passcode being utilizable to authenticate to a resource protected by the other device.

Near field communication based authentication

A technique involves the use of an electronic device having a real-time clock (RTC) circuit. In particular, the technique involves obtaining an RTC value from the RTC circuit. The RTC value is based on a previous time value and being arranged to represent current time. The technique further involves generating an adjustment factor arranged to adjust for imperfection in an oscillator of the RTC circuit, and providing a new time value based on the RTC value and the adjustment factor. The new time value represents current time at least as accurately as the RTC value.

RTC circuit with time value adjustment

An authentication device or other type of low-power hand-held device comprises a processor, an external button alternately configurable in an unpressed state and a pressed state, and current drain mitigation circuitry coupled to the external button and a corresponding input of the processor. The current drain mitigation circuitry is configured to connect the input of the processor to a first potential when the external button is in the unpressed state and to connect the input of the processor to a second potential different than the first potential when the external button is in the pressed state, thereby limiting current drain arising from the external button being stuck in the pressed state.
