Transparent authentication using biometric factors

A system, comprising:

• at least one processor;
• and
• one or more non-transitory media storing instructions that, when executed by the system, cause the system to perform operations comprising:
• determining, at an authentication system, that a primary device of a user has registered a secondary device to be used for authentication;
• receiving, at the authentication system, a request from the primary device for the user to access a secure resource via the primary device;
• determining that a user is wearing or has been implanted with a secondary device by:
• determining that the secondary device has detected a physiological parameter comprising at least one of a blood pressure, a blood oxygenation, a body temperature, a body movement, a blood electrolyte level, or a sweat electrolyte level;
• and
• determining that the physiological parameter matches a biometric signature of the user;
• determining a type of an input mechanism with which the secondary device receives data;
• determining a signal type of the signal such that the input mechanism is able to receive the signal as data, outputting, from the authentication system and to a primary device, an instruction to output a signal indicating a code, wherein the instruction indicates the signal type for the primary device to use when outputting the signal indicating the code;
• receiving, at the authentication system, a message from the secondary device, the message comprising:
• a representation of the code indicating that the secondary device detected the signal indicating the code that was output by the primary device;
• and
• an indication that the secondary device has utilized an authentication factor associated with user to confirm that the secondary device is located on or implanted in the body of the user;
• and
• enabling the user to access the secured resource via the primary device.

An authentication system, comprising:

• at least one processor;
• and
• memory storing instructions that, when executed by the system, cause the system to perform operations comprising:
• receiving, from a wearable device, a first signal;
• identifying, based on the first signal, a biometric signal that the wearable device has detected from a user, the biometric signal comprising at least one of a blood pressure of the user, a blood oxygenation of the user, a body temperature of the user, a body movement of the user, a blood electrolyte level of the user, or a sweat electrolyte level of the user;
• determining that the detected biometric signal matches a predetermined biometric signal associated with the user;
• outputting, to a primary device, an instruction to output a second signal indicating a code;
• receiving, from the wearable device, a third signal;
• determining, based on the third signal, that the wearable device has detected, from the primary device, the second signal indicating the code, wherein determining that the wearable device has detected the second signal indicating the code comprises determining that the wearable device has detected the second signal within a threshold time period of detecting the biometric signal of the user;
• receiving, from the primary device, a fourth signal;
• determining, based on the fourth signal, that the user has confirmed an authentication factor output by the primary device;
• and
• based on determining that the detected biometric signal matches the predetermined biometric signal, determining that the wearable device has detected the second signal, and determining that the user has confirmed the authentication factor, enabling the primary device to access a secured resource.
