Patent Application for Triple Authentication System – Utilizing Mobile Devices and Wearables.

Background & Need

Traditional authentication relies on passwords, security tags, or biometrics such as fingerprint or facial recognition. Passwords can be leaked, and biometric authentication often requires direct physical contact, creating inconvenience and security risks.

ENPLUG’s system solves these limitations with multi-factor authentication that also reflects the user’s health status and whether the wearable device is being worn. It provides not only identity verification, but also improved safety and security.

Key Technology

The core of this invention is the use of various biometric and sensor data collected from wearable devices — such as body temperature, heart rate, blood pressure, oxygen saturation, stress index, and alcohol detection.

• The wearable device sends the captured biometric information to a mobile gateway (authentication server).

• The server checks the registered authentication code and confirms whether biometric values are within normal range. If conditions are met, access is approved.

• During this process, the system also verifies whether the wearable device is actually being worn, preventing unauthorized use by someone else.

For example, if body temperature is outside the normal range, access may be restricted for infection control. If alcohol presence is detected, the system could prohibit vehicle ignition.

In short, the technology goes beyond simple security and can function as a safety and accident-prevention system.

Application Areas

This technology can be applied to a wide range of fields.

• Access control: Allows entry only after verifying a user’s health status in security zones, research labs, factories, or hospitals

• Vehicles & heavy equipment: Detects driver intoxication, fatigue, or drowsiness to prevent accidents

• Industrial sites: Restricts operations if abnormal signals such as high heart rate, blood pressure, or stress are detected

• Smart homes & appliances: Enables device and robot control through wearable authentication

In particular, it is highly useful in secure environments where smartphone use is restricted, since authentication can be performed directly through the wearable device.
Once validated, access rights can be automatically granted to various systems such as doors, cars, computers, medical devices, and more.

Future Plan

Through this invention, ENPLUG has introduced a new authentication paradigm that delivers both security and convenience.
The company is currently in the process of securing domestic patents and is also pursuing international patents to strengthen global market competitiveness.

An ENPLUG representative stated,
“This technology goes beyond simple access control. By combining smartphones with wearable devices, it provides an integrated security solution that also covers user health and safety.
We will continue to research and develop innovative authentication technology that can be used conveniently in everyday life.”
