Secure authentication using biometric factors

A computing device comprising:

• one or more communication units configured to receive, via a guard device, a first authentication factor from a biometric authentication device in a non-secure domain, wherein the first authentication factor comprises an identifier of a first prospective user of the biometric authentication device;
• and
• one or more processors configured to:
• determine whether the first prospective user is a trusted user of the computing device based on the first authentication factor;
• determine that the trusted user has a medic credential based on information stored in a user database stored on the computing device;
• and
• responsive to determining that the first prospective user of the biometric authentication device is the trusted user that has the medic credential, enable access to one or more applications on the computing device;
• after enabling the access to the one or more applications on the computing device, receive via the guard device, a second authentication factor from a secondary authentication device in the non-secure domain, wherein the second authentication factor comprises an identifier of a second prospective user, wherein the second prospective user comprises a user of the secondary authentication device;
• determine an identity of the second prospective user based on the received second authentication factor and the information stored in the user database;
• and
• determine medical treatment information about the second prospective user based on the identity of the second prospective user.

A non-transitory computer readable storage medium storing instructions that, when executed by one or more processors of a computing device, cause the one or more processors to:

• receive, via a guard device, a first authentication factor from a biometric authentication device in a non-secure domain, wherein the computing device is in a secure domain, wherein the first authentication factor comprises an identifier of a first prospective user of the biometric authentication device;
• determine whether the prospective user is a trusted user of the computing device based on the first authentication factor;
• determine that the trusted user has a medic credential based on information stored in a user database stored on the computing device;
• and
• responsive to determining that the prospective user of the biometric authentication device is the trusted user that has the medic credential, enable access to one or more applications on the computing device;
• after enabling the access to the one or more applications on the computing device, receive via the guard device, a second authentication factor from a secondary authentication device in the non-secure domain, wherein the second authentication factor comprises an identifier of a second prospective user, wherein the second prospective user comprises a user of the secondary authentication device;
• determine an identity of the second prospective user based on the received second authentication factor and the information stored in the user database;
• and
• determine medical treatment information about the second prospective user based on the identity of the second prospective user.
