Based on its i.MX RT106F crossover microcontroller, NXP offers EdgeReady for the IoT, with a license for facial recognition software to provide touchless access control.
OEMs can use EdgeReady to quickly, easily and inexpensively add vision-based touchless access control, says NXP. The microcontroller and AI/ML-based face recognition software makes possible face recognition with liveness checking using infra red and RGB cameras, flash and SDRAM at a total cost of less than US$10, says the company.
It can be used to implement face recognition for authenticating and operating secure machines, equipment, and access points for hotels, public buildings and homes, for example, doors, locks, amenities, lifts, garage doors and security systems.
The infra red camera operates with a visible light (RGB) camera to distinguish a real person from a photograph. This prevents unauthorised access without the need for an expensive 3D structured light or time of flight (ToF) camera, says NXP.
It responds in 0.5 seconds. Face detection, quality check, liveness detection and face recognition are all conducted in less than 500 milliseconds at the microcontroller-based edge instead of the cloud, to make access systems convenient.
It also enhances data privacy by allowing all personal biometric data to remain on the device at the edge. This helps address privacy regulations as well as the concerns of consumers to protect data.
The battery life is maximised with a fast microcontroller boot up time. The device enters power saving mode when not in use. A fast recognition time is combined with the microcontrollers low active power, says NXP, to further meet low power system requirements.
A customisable smartphone or PC application can enable biometric models to be sent to remote locks and other devices for controlled access in hospitality, smart building and smart home applications.
NXP also offers the i.MX RT106F-based development kit (SLN-VIZNAS-IOT) to accelerate time to market. It contains all the software and hardware information to complete designs in as little as six months, says NXP. In addition to negating integration and coding, the NXP EdgeReady IoT for secure face recognition based on the i.MX RT106F development kit includes schematics, bill of materials (BoM), board layout and ready-to-use face biometric registration application.
The SLN-VIZNAS-IOT secure face recognition development kit is available now from NXP and authorised distributors.
The i.MX RT106F microcontroller is available now. It includes a license to use the NXP face recognition SDK. The device is available in consumer and industrial temperature grades.
