Remotely authenticating using a mobile device

## Abstract

In general, in one aspect, the invention relates to a method for authenticating using a mobile device of a user. The method involves receiving a request for access to a secure resource and requesting credentials for accessing the secure resource from the user. The method further involves receiving a request to obtain the credentials from the mobile device, where the mobile device includes a mobile device user interface and a credential interface, and requesting the credentials from the mobile device. The method still further involves, in response to the credential interface authenticating the user on the mobile device using input received from the mobile device user interface, receiving the credentials from the mobile device. The method further involves determining that the user is authorized to access the secure resource based on the credentials and providing the user with access to the secure resource.

## Background
BACKGROUND
Security of information is an important consideration in a variety of modern transactions and storage. For example, electronic mail accounts and access to automated teller machines (ATM) are areas where authentication (i.e., proof or verification that the account being accessed is authorized by the owner of the account) have long been required. However, as fraud, identify theft, and similar activities become more prevalent, additional measures for protecting other devices and accounts may be necessary to fully protect information. Credit card transactions and certain telephone communications are examples where authentication is increasingly required in order to proceed with a transaction or complete a customer service call, respectively.
In all such cases where authentication is required, an account holder must be able to provide security information (i.e., credentials) in order to receive access to an account or other secure information. In some cases, the account holder is required to change such credentials on a periodic basis. In other cases, the credentials are complex, including a combination of secure passwords and personal questions. Account holders are often encouraged to avoid using credentials that are familiar, such as names of pets or children, or numbers in the form of birthdays or anniversaries. As the number of accounts that an account holder maintains increases, the account holder may have more difficulty remembering the various credentials and keeping such credentials secure.

FIGS. 2A-2B show a flowchart of a method for remote authentication using a mobile device in accordance with one or more embodiments of the invention. While the various steps in this flowchart are presented and described sequentially, one of ordinary skill will appreciate that some or all of the steps may be executed in different orders, may be combined or omitted, and some or all of the steps may be executed in parallel. In addition, a person of ordinary skill in the art will appreciate that other steps, omitted in FIGS. 2A-2B, may be included in this flowchart. Accordingly, the specific arrangement of steps shown in FIGS. 2A-2B should not be construed as limiting the scope of the invention.
Beginning with FIG. 2A, in step 202, a mobile device is configured to be associated with a user. More specifically, configuring the mobile device may allow the mobile device to send and receive credentials for accessing a secure resource. Step 202 may optionally be performed at any other time in the method described with respect to FIG. 2. Those skilled in the art will appreciate that initializing the mobile device may also include configuring settings related to the mobile device. In one or more embodiments of the invention, a particular computer, as described with respect to FIG. 5 below, is used to initialize the mobile device.
In step 204, credentials for a secure resource are received. In some cases, the credentials may be obtained from the user. In other examples, the credentials may be received as input from the user by manual entry, automatically uploaded from a different source, received by some other method, or any suitable combination thereof. In one or more embodiments of the invention, the credentials may be modified from an original version of the credentials, generating revised credentials. At this stage, the credentials may be associated with the secure resource to which the credentials provide access. In one or more embodiments of the invention, a particular computer, as described with respect to FIG. 5 below, is used to receive the credentials for the secure resource.
In step 206, a request to send the credentials to a mobile device of the user is received. In one or more embodiments of the invention, the request is sent to more than one mobile device, where each mobile device is initialized as described above with respect to step 202. Some form of authentication or verification, such as entry of a password or acknowledgement, may be required before the request may be verified as originating from the user. Communication with the mobile device may be established using a variety of manners, including but not limited to an application programming interface. Optionally, the user may provide the credentials by inputting the credentials directly into the mobile device. In any case, the request to send the credentials to a mobile device of the user may specify a data format supported by the mobile device. In one or more embodiments of the invention, a particular computer, as described with respect to FIG. 5 below, is used to receive the request to send the credentials to the mobile device of the user.
In step 208, the credentials are sent to the mobile device of the user. In one or more embodiments of the invention, the credentials are subsequently stored in the mobile device. The credentials may also be stored a remote location from the mobile device, such as, a remote server or a portable memory device. The credentials may be transmitted in a format supported by the mobile device. In one or more embodiments of the invention, a particular computer, as described with respect to FIG. 5 below, is used to send the credentials to the mobile device of the user.
In step 210, a request to access the secure resource is received. The credentials may be required to access the secure resource. The request to access the secure resource may originate from the user. In some cases, the request to access the secure resource may be sent to a resource server associated with the secure resource. In this case, the request to access the secure resource may be sent in a format supported by the resource server and/or the secure resource. In one or more embodiments of the invention, a particular computer, as described with respect to FIG. 5 below, is used to receive the request to access the secure resource.
In step 212, the credentials to the secure resource are requested from the user. In one or more embodiments of the invention, the credentials are the same as those described above with respect to steps 204-208. The credentials may be associated with the secure resource to which the credentials provide access. The credentials may be requested by a resource server managing access to the secure resource. In one or more embodiments of the invention, a particular computer, as described with respect to FIG. 5 below, is used to request the credentials to the secure resource from the user.
In step 214, a request is received to obtain the credentials from the mobile device. In one or more embodiments of the invention, the request originates from the user. The request may be a default setting, so that the request to receive the credentials from the mobile device is automatically received upon the completion of step 212. In one or more embodiments of the invention, a particular computer, as described with respect to FIG. 5 below, is used to obtain the request to receive the credentials from the mobile device.
In step 216, the credentials are requested from the mobile device. In one or more embodiments of the invention, the request to obtain credentials from the mobile device is sent on behalf of the user to the mobile device. The mobile device may be configured to authenticate the user before the request to obtain the credentials from the mobile device is verified. Examples of authentication may include, but are not limited to, inputting a password or personal identification number, voice recognition, and/or biometric input (e.g., fingerprint scan, retinal scan, etc.). The request to obtain the credentials from the mobile device may include identification information for the secure resource to which the credentials grant access. The request to obtain the credentials may also contain other information useful for establishing the appropriate credentials for the secure resource. The request to obtain the credentials from the mobile device may be sent in a format supported by the mobile device. In one or more embodiments of the invention, a particular computer, as described with respect to FIG. 5 below, is used to receive the request to obtain the credentials from the mobile device.
In step 218, a determination is made as to whether the user is authenticated on the mobile device. In one or more embodiments of the invention, the mobile device authenticates the user before the credentials may be obtained from the mobile device. Examples of authentication may include, but are not limited to inputting a password or personal identification number, voice recognition, and/or biometric input (e.g., fingerprint scan, retinal scan, etc.). If the user is not authenticated on the mobile device, then the process proceeds to step 240, where a notification is sent to the user that the user is not authenticated on the mobile device and the process ends. The user may not be authenticated on the mobile device if, for example, a password is incorrectly entered after a predetermined number of attempts or if a predetermined amount of time has lapsed before the correct authentication information has been received from the user. In one or more embodiments of the invention, a computer, as described with respect to FIG. 5 below, is used to present to user the notification that the user was not properly authenticated on the mobile device. If the user is authenticated on the mobile device, then the process proceeds to step 220, where the credentials are obtained from the mobile device. In one or more embodiments of the invention, a particular computer, as described with respect to FIG. 5 below, is used to determine whether the user is authenticated on the mobile device.
In step 220, the credentials are obtained from the mobile device. In one or more embodiments, the credentials are obtained in a similar manner as the request to obtain the credentials is transmitted. Optionally, the credentials may have been altered or modified by, for example, the user to generate revised credentials. In such a case, the revised credentials are sent by the mobile device. In any case, the credentials are sent in a format supported by the resource server and/or the secure resource. In one or more embodiments of the invention, a particular computer, as described with respect to FIG. 5 below, is used to receive the credentials from the mobile device.
In step 222, the credentials are sent to the resource server. If revised credentials were received from the mobile device, as described above with respect to step 220, then the revised credentials are sent to the resource server. In one or more embodiment of the invention, step 222 may be omitted if the resource server is configured to receive the credentials directly from the mobile device. In one or more embodiments of the invention, a particular computer, as described with respect to FIG. 5 below, is used to send the credentials to the resource server.
In step 224, a determination is made by the resource server as to whether the user is authorized to access the secure resource based on the credentials. If the user is not authorized to access the secure resource based on the credentials, then the process proceeds to step 250, where a notification is sent to the user that the credentials are not valid and the process ends. In one or more embodiments of the invention, a particular computer, as described with respect to FIG. 5 below, is used to present to the user the notification that the credentials are invalid. If the user is authorized to access the secure resource based on the credentials, then the process proceeds to Step 226, where the user is provided with access to the secure resource. In one or more embodiments of the invention, a particular computer, as described with respect to FIG. 5 below, is used to provide the user with access to the secure resource.
FIGS. 3A-4B illustrate examples for remote mobile device authentication in accordance with one or more embodiments of the invention.
