Multi-level user device authentication system for internet of things (IOT)

A method for granting access to information by a first device, the method comprising:

• receiving, by the first device, a request for access to information from a second device, the second device being a first Internet of Things (IoT) device;
• sending, by the first device, a request for a phone number to the second device;
• receiving, by the first device, the phone number;
• determining, by the first device, a user profile associated with the phone number;
• determining, by the first device, a third device corresponding to the user profile, the third device being a second Internet of Things (IoT) device;
• sending, by the first device, a request for biometric authentication using biometric information obtained on the third device to the third device;
• receiving, by the third device, the request for biometric authentication;
• obtaining, by the third device, first biometric information;
• determining, by the third device, that first biometric information obtained on the third device matches second biometric information saved on the third device;
• receiving, by the first device, a message indicating that the biometric information has been authenticated by the third device;
• sending, by the first device, instructions granting the request for access to information to the second device;
• and
• sharing, by the first device, the information with the second device.

• determining, by the third device, a second device associated with the user profile, the second device being a second Internet of Things (IoT) device;
• sending, by the third device, a first message to the second device associated with the user profile, the first message requesting user authentication on the second device using biometric information obtained on the second device;
• receiving, by the second device, the first message requesting user authentication on the second device using biometric information;
• obtaining, by the second device, first biometric information;
• determining, by the second device, that first biometric information obtained on the second device matches second biometric information saved on the second device;
• receiving, by the third device, a second message from the second device, the second message validating authentication based on the biometric information obtained on the second device;
• and
• sending, by the third device, a third message to the first device granting access to information to the first device based on the second message validating authentication.
