Multilevel authentication using a mobile device

1. A computer-implemented method for using a mobile device to authenticate a user to access a secure facility, the method comprising:

determining, by an authentication service, whether the mobile device of the user is locked when the user approaches the secure facility and when the mobile device is connected to the authentication service through a wireless network at the secure facility;

in response to determining that the mobile device is locked, requesting, by the authentication service, the user to unlock the mobile device, and determining whether the user has unlocked the mobile device;

in response to determining that the user has unlocked the mobile device, retrieving, by the authentication service, from the mobile device, a first token and a media access control (MAC) address;

retrieving, by the authentication service, from a database of the authentication service, a token identifier registered for the mobile device and a personal identifier registered for the user;

generating, by the authentication service, a second token, based on the token identifier and the personal identifier retrieved from the database and based on the media access control (MAC) address retrieved from the mobile device;

determining, by the authentication service, whether the first token and the second token match; and in response to determining that the first token and the second token match, granting, by the authentication service, the user access to the secure facility;

in response to determining, when the user approaches the secure facility and when the mobile device is connected to the authentication service through a wireless network at the secure facility, that the mobile device is not locked, rejecting, by the authentication service, the user the access to the secure facility, and requesting the user to lock the mobile device.

A computer program product for using a mobile device to authenticate a user to access a secure facility, the computer program product comprising one or more computer-readable tangible storage devices and program instructions stored on at least one of the one or more computer-readable tangible storage devices, the program instructions executable to:

determine, by an authentication service, whether the mobile device of the user is locked when the user approaches the secure facility and when the mobile device is connected to the authentication service through a wireless network at the secure facility;

in response to determining that the mobile device is locked, request, by the authentication service, the user to unlock the mobile device, and determine whether the user has unlocked the mobile device;

in response to determining that the user has unlocked the mobile device, retrieve, by the authentication service, from the mobile device, a first token and a media access control (MAC) address;

retrieve, by the authentication service, from a database of the authentication service, a token identifier registered for the mobile device and a personal identifier registered for the user;

generate, by the authentication service, a second token, based on the token identifier and the personal identifier retrieved from the database and based on the media access control (MAC) address retrieved from the mobile device;

determine, by the authentication service, whether the first token and the second token match; and

in response to determining that the first token and the second token match, grant, by the authentication service, the user access to the secure facility, wherein the secure facility comprises a building and the granting the user access to the secure facility comprises unlocking an entry door;

in response to determining, when the user approaches the secure facility and when the mobile device is connected to the authentication service through a wireless network at the secure facility, that the mobile device is not locked, rejecting, by the authentication service, the user the access to the secure facility, and requesting the user to lock the mobile device.

8. The computer program product of claim 7 , further comprising the program instructions executable to: in response to determining that the user has not unlocked the device, reject, by the authentication service, the user the access to the secure facility.

9. The computer program product of claim 7 , further comprising the program instructions executable to: in response to determining that the first token and the second token do not match, reject, by the authentication service, the user the access to the secure facility.

10. The computer program product of claim 7 , further comprising the program instructions executable to: in response to determining that the first token and the second token match, generate, by the authentication service, a certificate for the user to access the secure facility; and deploying, by the authentication service, the certificate on the mobile device.

11. The computer program product of claim 10 , further comprising the program instructions executable to: retrieve, by the authentication service, from the mobile device of the user, the certificate; determine, by the authentication service, whether the certificate is expired; and

in response to determining that the certificate is not expired, check, by the authentication service, access policies; and in response to determining that the access policies grant the user to access, grant, by the authentication service, the user the access to the secure facility.

12. The computer program product of claim 11 , further comprising the program instructions executable to: in response to determining that the certificate is expired, request, by the authentication service, the user to extend the certificate.

13. A computer system for using a mobile device to authenticate a user to access a secure facility, the computer system comprising:

one or more processors, one or more computer readable tangible storage devices, and program instructions stored on at least one of the one or more computer readable tangible storage devices for execution by at least one of the one or more processors, the program instructions executable to:

determine, by an authentication service, whether the mobile device of the user is locked as the user approaches the secure facility and when the mobile device is connected to the authentication service through a wireless network at the secure facility; in response to determining that the mobile device is locked as the user approaches the secure facility, request, by the authentication service, the user to unlock the mobile device, and determine whether the user has unlocked the mobile device;

in response to determining that the user has unlocked the mobile device, retrieve, by the authentication service, from the mobile device, a first token and a media access control (MAC) address;
