## Background
CROSS-REFERENCED TO RELATED APPLICATIONS
The present application is a continuation of U.S. patent application Ser. No. 13/915,086 filed on Jun. 11, 2013, which is a continuation of U.S. patent application Ser. No. 13/540,685 filed on Jul. 3, 2012.


BACKGROUND
Embodiments of the present invention generally relate to identification documents. More particularly, embodiments relate to the authentication of electronic identification documents.
Driver's licenses and other identification documents may be issued by state governments to individuals, wherein the individuals may be required to present the licenses to various other third parties such as airport security, customs, immigration, police, nightclubs, controlled beverage stores, banks, credit card merchant account processors, firearm vendors, military sites, employers, etc. A common security concern may exist at a local, state, national, and even global level with regard to the creation and use of forged (e.g., fake) driver's licenses. Indeed, a significant market may exist for forged driver's licenses that might be used as false evidence of U.S. citizenship. For example, certain counterfeiters may be able to recreate watermarks, holograms, UV (ultraviolet) veneer coatings, etc., on physical licenses to a high level of precision and in many different contexts. While the use of electronic identification (ID) documents may be a potential solution, there remains considerable room for improvement. For example, the need to be able to present licenses to a wide variety of third parties can pose implementation difficulties that may not be addressed by conventional electronic ID solutions.

Referring now to FIGS. 1A-1C, issuance, presentation, and challenge stages of an electronic identification (ID) document are shown, respectively. With specific reference to FIG. 1A, a certificate authority 10 may respond to a document request from a user/individual 12 having a mobile device 14 such as a smart phone, smart tablet, personal digital assistant (PDA), and so forth. The certificate authority 10 may be associated with, for example, a state department of motor vehicles (DMV) that is authorized to issue driver's licenses and other ID documents to individuals such as the user 12. In one example, the user is required to pay for the requested electronic ID document, wherein the certificate authority 10 might verify payment for the ID document by the user 12 prior to issuing the requested document. The certificate authority 10 could also verify other aspects of the document request such as the satisfactory completion of various driver licensing requirements (e.g., age, written certification, road certification, vision certification, etc.).
Upon verifying the appropriate document issuance requirements, the illustrated certificate authority applies an encryption key 16 to an ID document 15 to obtain an encrypted ID document 18, wherein the encrypted ID document 18 may constitute, for example, a read only driver's license having a photograph of the user 12. Other examples of photo ID documents that may be encrypted include, but are not limited to, passports, military IDs, and employment IDs, the certificate authority 10 may then send the encrypted ID document 18 along with a decryption key 20 associated with the encryption key 16 to the mobile device 14. In one example, the certificate authority 10 applies a signature to an expiration date of the encrypted ID document 18 prior to sending them to the mobile device 14. Such an expiration date signature could be particularly advantageous with regard to driver's licenses, temporary employee ID badges, etc. The decryption key 20 may also be packaged as a password protected PK12 file or a non-password protected PK8 file. Indeed, the encrypted ID document 18 and decryption key 20 might be packaged together into an application (e.g., Android License Identity/ALI app) that is signed and downloaded onto the mobile device 14 via a wired or wireless connection. Of particular note is that the illustrated certificate authority 10 maintains the encryption key 16 in a secure state that is inaccessible by other parties. Moreover, the read only nature of the encrypted ID document 18 can further reduce the likelihood of tampering with the underlying photograph and/or other ID content.
The certificate authority 10 may also make the decryption key 20 generally available to other parties and/or devices such as, for example, a challenge terminal 22. The challenge terminal may be associated with another entity such as, for example, airport security (e.g., Transportation Security Administration/TSA), police (e.g., state and/or local), nightclubs, controlled beverage stores, banks, credit card merchant account processors, firearm vendors, military sites, employers, etc. For example, the certificate authority 10 could publish the decryption key to an appropriate publication source such as a web portal, directory, listing, subscription service, etc. As will be discussed in greater detail, the challenge terminal 22 may also obtain the decryption key 20 from the certificate authority directly via a key request, and so forth.
With particular reference to FIG. 1B, a presentation stage is shown. Generally, upon receipt of the encrypted ID document 18 and decryption key 20 from the certificate authority 10 on the mobile device 14, the encrypted ID document 18 and decryption key 20 may be stored to local memory on the mobile device 14 and the illustrated user 12 may carry the mobile device 14 with him or her in place of a physical ID document. More particularly, if the user 12 enters a physical area associated with the challenge terminal 22 and is asked (e.g., by police officer, TSA agent, bouncer, etc., not shown) to present identification, the user 12 may use a touch screen 24 or other suitable user interface (UI) of the mobile device 14 to initiate a display request. Indeed, the user 12 may even be remote from the challenge terminal 22, wherein the user 12 might participate in a video conferencing session (e.g., Skype session) with the person checking the ID of the user 12. In response to the display request, the mobile device 14 may apply the decryption key 20 to the encrypted ID document 18 to obtain a decryption result 26, and output the decryption result 26 via the touch screen 24 or other appropriate display of the mobile device. Accordingly, the user 12 may then show the decryption result 26 to the requesting individual (e.g., police officer, TSA agent, bouncer, etc.) associated with the challenge terminal 22.
As already noted, the encrypted ID document 18 may include a photograph 28 of the user 12 or of the person whom the user 12 is impersonating. Thus, the requesting individual associated with the challenge terminal 22 may decide based on, for example, visual differences between the user 12 and the photograph 28, suspicions regarding the identity, age, residence and/or citizenship of the user 12, random selection, etc., that the displayed decryption result 26 may not be trustworthy. In such a case, the requesting individual associated with the challenge terminal 22 can instruct the user 12 to initiate a challenge request on the mobile device 14.
FIG. 1C demonstrates that the challenge request, which may be initiated via the touch screen 24 or other suitable UI of the mobile device 14, can cause the mobile device 14 to send the encrypted ID document 18 to the challenge terminal 22. In one example, the information is transferred to the challenge terminal 22 via a wireless interface (e.g., Bluetooth, infrared/IR, Wi-Fi, NFC/Near Field communication, etc., not shown). In another example, a “bump” interaction between the mobile device 14 and the challenge terminal 22 can be used to initiate the challenge request. In such a case, NFC technology may be used to detect the proximity/bump interaction, wherein the transferred information could be sent through the Internet to the challenge terminal 22. The illustrated challenge terminal 22, which may be any suitable computing system such as a work station, desktop computer, notebook computer, smart tablet, mobile device, etc., can receive the encrypted ID document 18 (e.g., via a wireless and/or Internet interface) and apply the decryption key 20 to the encrypted ID document 18 to obtain a decryption result 30. The illustrated decryption result 30 is output via a display 32 of the challenge terminal 22. The decryption key 20, which may be obtained offline or in real-time from a suitable key publication source or directly from the certificate authority 10 (e.g., via explicit key request), can therefore provide the requesting individual associated with the challenge terminal 22 with an additional identity verification mechanism.
More particularly, if the encrypted ID document 18 received from the mobile device 14 is anything other than the document encrypted by the certificate authority 10 using the secure encryption key 16, the decryption result 30 will be illegible, in the example shown. Indeed, the read only nature of the encrypted ID document 18 can further reduce the likelihood of tampering with the underlying photograph and/or other ID content, as already noted. Additionally, if the user 12 tampers with the decryption result 26 (FIG. 1B) shown at the presentation stage (e.g., to change the birth date on the driver's license) or shows a different ID document at the presentation stage, the requesting individual associated with the challenge terminal 22 may readily be able to see the differences between the forged ID document shown on the touch screen 24 of the mobile device 14 and the legitimate ID document shown on the display 32 of the challenge terminal 22. Thus, any forgery attempts on the part of the user 12 may be readily detected in the illustrated example.
FIG. 2 shows a method 34 of issuing an electronic ID document. The method 34 may be implemented in a server of a certificate authority such as, for example, the certificate authority 10 (FIGS. 1A-1C), already discussed. Illustrated processing block 36 provides for receiving a document request, wherein an encryption key may be applied to an ID document at block 38 in response to the document request. In one example, block 38 also involves verifying payment for the identification document by an individual associated with the document request, as well as verifying other parameters such as age, citizenship, driving record, and so forth. The encrypted ID document and a decryption key associated with the encryption key may be sent at block 40 to a mobile device, wherein the encryption key can be maintained in a secure state.
FIG. 3 shows a method 42 of operating a mobile device. The method 42 may be implemented in a mobile device such as, for example, the mobile device 14 (FIGS. 1A-1C), already discussed. Processing block 44 can provide for receiving an encrypted ID document and decryption key, wherein the received information may be stored to local memory of the mobile device. In response to receiving a display request at block 46, illustrated block 48 applies the decryption key to the encrypted ID document to obtain a decryption result. The decryption result may be output to a display of the mobile device at block 50. If it is determined at block 52 that a challenge request has been received, illustrated block 54 sends the encrypted ID document to a challenge terminal, as already discussed. In one example, the encrypted ID document is sent to the challenge terminal via a wireless interface.
FIG. 4 shows a method 56 of challenging an electronic ID document. The method 56 may be implemented in a challenge terminal such as, for example, the challenge terminal 22 (FIGS. 1A-1C), already discussed. Processing block 58 may provide for obtaining a decryption key originating from a certificate authority. Block 58 might involve obtaining the decryption key from a publication source or by sending a key request to a certificate authority server. An encrypted ID document may be received at block 60 from a mobile device in accordance with a challenge request. In one example, the encrypted ID document is received via a wireless interface such as a Bluetooth, IR, NFC interface, etc. The encrypted ID document might also be obtained via an Internet interface of the challenge terminal (e.g., using the Internet as a proxy in response to a bump interaction). Illustrated block 62 applies the decryption key to the encrypted ID document to obtain a decryption result, wherein the decryption result may be output to a display of the challenge terminal at block 64.
The person presenting the encrypted ID document could be either co-located with the challenge terminal or remote from the challenge terminal (e.g., participating in a video conferencing session). For example, the person presenting the encrypted ID document might be in the process of opening a credit card merchant account, wherein photo identification is required in order to complete the process. In such a case, the encrypted ID document may be emailed to the account authorization personnel, who may decrypt the encrypted ID document as described herein and visually verify the photograph against the person presenting the ID document in a video conferencing session. Such an approach may make it virtually impossible to forge photo IDs even in distributed/remote authentication settings.
FIG. 5 shows a networking architecture 66 in which a certificate authority server 70 includes license issuing application 72 that issues an encrypted ID document and corresponding decryption key in the form of a mobile application 74 to a user equipment (UE) device 68 over a network 76. In one example, the mobile application 74 applies the decryption key to the encrypted ID document to obtain a decryption result in response to a display request, and outputs the decryption result via a display of the UE device 68. In response to a challenge request, the mobile application 74 may send the encrypted ID document to a challenge terminal 78, wherein the certificate authority server 70 may also provide the challenge terminal 78 with a third party application 80 over the network 76. In one example, the third party application 80 is configured to apply the decryption key to the encrypted ID document to obtain a decryption result, and output the decryption result to a display of the challenge terminal 78. The network 76 can itself include any suitable combination of servers, access points, routers, base stations, mobile switching centers, public switching telephone network (PSTN) components, etc., to facilitate communication between the server 70 and the UE device 68 and challenge terminal 78. The UE device 68 and the challenge terminal 78 may communicate directly over a wireless link such as, for example, a Bluetooth, IR, Wi-Fi, NFC link, etc., or indirectly through the network 76. Moreover, the UE device 68 and the challenge terminal 78 may be engaged in a bump interaction in order to initiate the challenge request, as already discussed.
