INCORPORATION BY REFERENCE
Applicant incorporates by reference herein United States publication no. 2012-02402G4-A1, entitled “System, Design and Process for Strong Authentication using Bidirectional OTP and Out-of-Band Multichannel Authentication.”
FIELD OF THE INVENTION
The field of invention relates to network and Internet security. The present invention relates to an authentication system and authentication method and in particular to a process and design for a multi-factor, out-of-band multi-channel authentication process to protect all documents or other data objects.
BACKGROUND OF THE INVENTION
Authentication of a user and his credentials is the first line of defense. User authentication involves confirming the identity of a user and validating that a user is trusted and can use a computer resource based on his credentials. Most people protect their online accounts using some form of passwords. On an average a typical user has about 20 accounts for which they need to remember passwords. Most users utilize the same password for most accounts just to make it easier to remember. This practice makes all accounts vulnerable and makes it easier for a hacker to break into all other accounts if one of the accounts is compromised.
ID's can be lost or stolen during transactions (whether its login, payment, or other transactions), and ID's must be presented in many places explicitly. For example, in the process of electronic payment, one's credit card details must be presented to a counter party. Although an ID in a transaction may be encrypted, there are still many possibilities that an ID can be lost or stolen.
Static or fixed password is a common form of authentication method in use today.
In the static password authentication method, the user enters static user id and password on a client site and submits. Then the request is sent to the authentication server to validate the credentials of the user. If the credentials are valid the user is traversed to the next page.
With static password, keeping the accounts secure and hack proof is a difficult task. To keep his accounts from being compromised, the user must select long, difficult to predict passwords. Most users use some of their personal information to create their password thus making it easier to remember. In addition, users have a tendency to use the same password for most of their accounts as remembering multiple passwords can be quite a challenge.
Protecting documents is several orders of magnitude more difficult due to (a) the much larger number of objects to be protected, (b) the difficulty of applying multi-factor authentication, and (c) the need to distribute the passwords among multiple recipients of the document(s).
An object of the present invention is to provide an authentication system, authentication method, and key distribution method which permit improvement in the security of the document storage and distribution process while making it easier to use than existing methods. The invention utilizes bi-directional, asynchronous, out-of-band authentication.
One embodiment according to the invention is based on a multi-dimensional QR Code which provides a vehicle for strong authentication, ease of use, minimal switching cost and lower total cost of ownership.
In addition, or in the alternative, an embodiment uses Bluetooth in place of the QR Code.
In addition, or in the alternative, an embodiment uses NFC in place of the QR Code.
In addition, or in the alternative, an embodiment uses computer generated sound in place of the QR Code.
By utilizing the multi-dimension bar code, NFC, Bluetooth, or Audio, the invention, as described herein, improves usability and eliminates key security issues.
The method, according to the invention, uses shared keys protected with each recipient's private key (e.g from a public/private key pair) distributed via a central point to a key store on a personal device, such as a smartphone. The device communicates with various document rendering and manipulation tools via the aforementioned QR code, Bluetooth, NFC, or Audio, and out-of-band communications to decrypt the document(s) on demand. A document may be protected with multiple keys to permit different recipients to view different subsets of the document. This method also provides for partial or total document invalidation or redaction after delivery.
SUMMARY OF THE INVENTION
The instant invention provides an easy to use authentication and credential management mechanism for multi-factor out-of-band multi-channel authentication process to protect all documents. This invention provides a strong method for document authors or distributors to protect the documents they store or deliver to others. This system authenticates access to the documents based on an out-of-band authentication mechanism.
The authentication seeker or system user scans the multi-dimensional barcode or via other embodiments, such as Bluetooth, NFC, computer generated sound, etc., validates the client, and triggers the out of band outbound mechanism. The portable mobile device invokes the client server for authentication. The client server authenticates the user based on a shared secret key and facilitates the transmission of the relevant document password, permissions, and/or other credentials to the document tool, which then unlocks the document.
This invention protects the users from Key logger, Dictionary attacks, Replay attacks, and Phishing attacks, as well as a multitude of attacks against the uncontrolled storage of the document password at rest.
The process of the invention includes: a Secure Document Application, comprising of either a single application incorporating this invention, or two applications, one for manipulating documents, and a second one for creating a connector between the document application, the authentication server, and the authentication server application. The authentication server application communicates with the client device and the Secure Document Application (e.g. multi-dimensional barcode or SSL), handling incoming requests, secret keys, and a portable communication device with an online application.
A preferred embodiment of the present invention utilizes a client/server system, which comprises an authentication server, a Secure Document Application, and a user hand held mobile device equipped with a camera or reader all of which are connected via a network. The Secure Document Application and the authentication server achieve mutual secure connection based on secure sockets layer (SSL). The handheld device is also connected to the network and can connect to the authentication server in a secure manner using SSL.
In an embodiment, a user who wants to view a document using this invention opens a protected document on his/her computer using the Secure Document Application. This application detects that the document requires user credentials and generates a multi-dimensional dynamic barcode, or invokes another transmission mechanism, such as Bluetooth, NFC, or computer generated sound, based on the online service client/server information including, but not limited to a document identifier, a dynamically generated key, and a unique session ID. These credentials are then presented to the user.
The Secure Document Application, at that point, contacts the authentication server and informs it that the secure document application is waiting for user credentials for this specific document with a specified session ID. The user starts the online application on the hand-held device that includes the authentication client application and camera. The user provides its authentication information, such as a PIN or Gesture, and/or additional biometric signatures, such as face match, voice print match, etc.
The handheld device then establishes an independent secure connection over a carrier network wireless connection or Wi-Fi connection to the authentication server using SSL. The online application validates the user PIN/Gesture, as well as the biometric profile, with the authentication server. The online application on the hand held device decrypts/decodes the barcode and ensures the validity of the request. This unique client validation mechanism ensures there are no phishing attacks.
Once the validity of the secure document application is ensured, the online application takes the extracted data from the bar code, looks up the password of the document in a secure credentials database by extracting the document identifier from the request. If the credentials for that secured document are not found in the secure credentials database, the online application presents a screen to the user to provide the credentials for that login portal. Once the user provides the credentials, the online application saves the credentials on the secure credentials database on the hand held device for future use.
The online application then sends user credentials for the document along with the unique session ID to the authentication server directly using this secure out-of-band channel. If the authentication server finds the user and the session ID valid, it contacts the waiting Secure Document Application using the session ID and passes the user credentials, as well as user roles/privileges. Based on the user roles/privileges, the Secure Document Application can automatically provide specified access to the allowed service components for which the user has been authorized.
In this embodiment, the user experience is simplified and only requires the user scanning the barcode presented on the screen or just be in close proximity to the computer in the case of using NFC, Bluetooth, or computer generated sound. From the user's perspective, once the scanning of the barcode is done, if the user credentials are valid, the process of opening the document proceeds based on the user rights.
It is to be understood that both the foregoing description and the following description are exemplary and explanatory only and are not restrictive of the invention, as claimed. Specific examples are included in the following description for purposes of clarity, but various details can be changed within the scope of the present invention.

DETAILED DESCRIPTION OF THE INVENTION
Referring to the drawing, FIG. 1 illustrates an embodiment of a system and process according to the invention. In particular, FIG. 1 shows an authentication system 10 that utilizes out-of-band outbound multi-channel authentication using a client/server system comprising an authentication server 12, browser having client processing 14, such as plug-ins or extensions, and a user hand held mobile device 16 equipped with a camera and with online authentication client, all of which are connected via a communications network 116 to access an online account server.
The browser plug-in and the authentication server can achieve mutual secure connection, based on a connection such as Secure Sockets Layer (SSL). The handheld device is also connected to the network and can connect to the authentication server in a secure manner using a connection such as SSL.
FIG. 6 illustrates one example of the two separate communication channels in present invention that are used for authentication process. The handheld device 16 communicates with the authentication server 12 over a first communications channel 18 which is separate from a second communications channel 20 over which the browser having the client processing application 14 and authentication server 12 communicate. In one embodiment of a system and process according to the invention, at least the out-bound portions of communications from the handheld device to the authentication server are provided in a separate communications channel 18 and are out-of-band from the communication channel 20 over which the authentication server 12 and client processing application 14 communicate.
The authentication server 12 compares the user information and the third party server credentials to a database of user information and a database of third party server credentials. The authentication server 12 authenticates the user information and the third party server credentials to obtain authentication results. The authentication server 12 transmits E1 the authentication results to the client processing application 14 and can also transmit E2 the authentication results to the portable communications device 16. The client processing application 14 also transmits E3 the authentication results to the hand held device 16. If the authentication results are positive, a secure communication may be established between the user and the client processing application 14, and the user 15 may be granted access by the client processing application 14. Alternatively, if the authentication results are negative, the user is denied further access to the client processing application 14.
FIG. 2 illustrates the components of an embodiment of a portable communication device 16 according to the invention, such as a handheld device like a mobile phone or an iPad. The portable communications device can include various components, including a processor 30, memory 32, power unit 34, keyboard 36, camera 38, a near field communication (“NFC”) unit 40, LCD Display 42 and a communications unit 44. The device also has an operating system 50 which includes programming for the processes utilized by the device, including programming for secure communication 52, a data storage 54 as well as a sandbox 56, containing an authentication application 58 and other supplemental applications 59 to supplement the processes of the authentication application 58. The sandbox provides a security mechanism for separating running programs and thereby enhances the security of a device according to the invention. Incorporation of an NFC unit 40 in a device according to the invention facilitates use of a device according to the invention by a user in a manner which can make the underlying processes appear seamless. It can be appreciated by a person of ordinary skill in the art to use known processes for the device Including processes for providing secure communication 50 by the device 16 to provide for secure receipt and transmission of information. Other applications 59 include software (and there may be hardware capabilities/applications/libraries on the phone) that provide capabilities like picture taking and touch sensitive activity detection.
FIG. 3 illustrates an embodiment of an authentication application having processes that may reside in the handheld portable communication device described in FIG. 2. It can be appreciated by a person of ordinary skill in the art that various programming can be provided to effect the processes of a device 16 according to the invention. The processes can be programmed into one or more separately discrete units. Among other things, a secure data storage 60 process can be provided to effect secure storage and retrieval of information from memory 32 on the device 16. Among other things, the secure data storage 62 and credentials 63 can include one or more shared secret keys associated with one or more client processing applications 14. In addition, a user face profile 64 can be provided for a face profile for use with the processes performed by the device 16. The authentication application 14 can also include separate processes for managing and storing other information, such as user credentials 66, a user pin 68, user secret key 70, and an authentication server shared secret key 72 which can be stored in the secure data storage 62 or in other portions of the memory 62. Furthermore, the device 16 includes processes for a barcode scanner and decoder 74 and a barcode encoder 76, which processes can be provided separately or as part of the authentication application 58 process software. The components and arrangements of FIGS. 2 and 3 may be varied within the principles of the present application.
Referring to FIGS. 1 and 4, client user starts E1 a client processing application 14 with laptop or PC, which can be automatically started once a user desires to login to an associated online account or portal. For example, the user can open a browser to log in to a password-protected website. Thereafter, the browser can load the URL.
The client processing 14 checks the URL E2 to determine whether or not the associated website requires credentials. The client processing 14 can do this by checking a secure database. If the website requires credentials, the client processing extension can request the browser to show an icon on the browser address bar to show availability of the instant invention to provide secure connection and the needed credentials. In this embodiment, the browser displays the icon, and if the user clicks on the icon the browser detects the extension icon selection to proceed and the browser extension and/or client processing 14 generates a session ID, a temporary public/private key pair and creates a payload for a QR Code with the session ID, temporary public key URL, client IP, and any other relevant information. Thereafter, the browser client processing 14 contacts E2 the authorization server 12 to start a new authorization session and the server generates a session ID 80 to send E3 to the client processing application. The client processing application 14 creates 82 a multi-dimensional barcode with dynamic encryption keys, server portal information, session and a unique key and displays the barcode in a popup. The client processing application waits for notification.
Further, or in the alternative, the client extension processing 14 can create the QR code with the payload created earlier and updates the pop-up contents. Thereafter the browser can bring up a pop-up containing a QR code for the user to scan.
In addition to or in the alternative, the client processing application 14 and/or browser extension contacts the authentication server with the session ID, and the authentication server can add the session ID to a list of pending authentication requests.
In addition, or as an alternate, the client processing application 14 creates an RSA key and embeds public key in bar code along with portal information, and displays barcode on laptop or PC screen.
User starts authentication 86 by using a smart phone and starting the handheld authentication application 59, or automate power application and entering E4 PIN or gesture on handheld device 16 to access the application. The alternate phone application prompts and accepts the PIN and then sends the device ID (which can be set up upon initialization of services), phone number and device ID/passcode to the authentication server 12.
Authentication server 12 receives the PIN/passcode with the device ID and checks against a secure database for a match for the device to login to the authentication server. If the match is successful, the authentication server returns notification and/or a password to the handheld device application 59 indicating success, and accordingly completes a process which validates the PIN and can, alternatively, or in addition, display one or more scan options 88.
User holds 90 handheld device to laptop or PC login screen and clicks scan option E5. Device scans barcode and validates the client processing application 92. On notification E6, the handheld device 16 finds 94 the encrypted user credentials with encryption key from barcode and sends E7 the encrypted credentials and session ID to authentication server 12. Authentication server 12 checks 96 in provisioned user database, validates session, and sends E8 encrypted payload to waiting client processing application 14. The client processing application decrypts 98 payload using the keys it generated and extracts the credentials. The client processing application 14 then uses the decrypted credentials to provide access to login to the online account and/or web portal and proceed to use those services of the online account.
Handheld device 16 displays result received E9 from the authentication server.
The out-of-band outbound mechanism provides an additional level of security due to the original request being different than the outgoing push from the portable device to the service provider server.
The usability issue is addressed by utilizing the scanning functionality of the hand held device. This eliminates erroneous typing and user frustration.
FIG. 5 shows a high level, less detailed and alternative embodiment of a method according to the invention shown in FIG. 4. A further embodiment, includes one or more variation of the methods and steps described above, and can include one or more of the following.
A method for authentication typically resides in a system comprising a user, a browser extension or plugin, a portable communications devices, and an authentication server having a provisioned user database and encrypted payload.
The method can begin by detecting user intent to login to an online portal (like, gmail, yahoo, ebay, etc) using a browser, and then establishing contact between browser extension or plugin and authentication server wherein a new authentication session is started.
Thereafter, a session ID can be generated at the authentication server, wherein the session ID is communicated to the browser plugin through at least a first communications channel.
A multi-dimensional barcode can be created at the browser extension or plugin, wherein the barcode has dynamic encryption keys, portal information, session ID, and a unique key, and wherein the barcode is displayed in the browser.
In one embodiment, the browser can be held in a waiting state pending authentication server notification of session validation, whereupon once positive notification is received the user starts the authentication by entering credentials on the portable communications device, wherein the portable communications device validates the credentials and displays one or more scan options.
In one embodiment, a portable communications device can be used to scan barcode displayed at login screen and validate browser extension or plugin. However other techniques of coded transmission including, but not limited to NFC, RFID, and Bluetooth, can be used within the scope of the invention.
Once the encrypted user credentials are located on the portable communications device with encryption key from barcode (or an alternative technique of transmission), the encrypted credentials are sent with the session ID from the portable communications device to authentication server via an outbound out-of-band communications channel.
Then, a matching of information is checked in the provisioned user database of authentication server, and the session is validated. Once validated, the encrypted payload is sent to the waiting browser extension or plugin, and validation result can be sent from the authentication server to the portable communication device where the result can be displayed.
The payload can be decrypted at the browser extension or plugin using encryption keys; and credentials can be extracted and decrypted at the browser extension as well.
Using decrypted credentials the login form on the login page of the online portal in the browser can be populated or transmitted directly to initiate and/or complete the login requirements of the online portal, such as by sending the login form to the online portal using the browser extension or plugin.
Similarly, as shown in FIGS. 4 and 5, a method according to the invention can include a number of steps. One possible variation of a method according to the invention is set forth as follows. A user 118 interacts 130 with a client processing application 117.
The client processing application 117 contacts 131 and authorization server 113 to start a new session. The authorization server 113 starts a new session and generates 132 a session ID.
The authorization server 113 communicates with the secure client processing 117 and provides information, including among other things, session ID information.
The client processing application 117 creates 133 a multi-dimensional barcode with barcode information. Including dynamic encryption keys, server/portal information, session ID and a unique key. The client processing application can display the generated barcode.
The client processing application waits 134 for receipt of a notification from the authorization server to proceed.
The barcode that has been generated by the client processing application 117 is displayed by the application. The user 118 can scan the barcode with the handheld device 1. The handheld device scans the barcode and validates 138 the service server.
The handheld device finds 139 encrypted the user credentials with encryption key from the barcode and sends validation information including the encrypted credentials and the session ID to the authentication server.
The authorization server receives the validation information, including the encrypted credentials and the session ID and checks 140 the provisioned user database and validates and sends encrypted payload to the waiting client processing application as notification.
The client processing application 117 decrypts 141 the payload from the authorization server using the keys it generated and extracts the credentials. The client processing application then uses the decrypted credentials to provide access to the login portal of the online account or service.
Accordingly, the handheld device can also display and/or access 142 the online account or service. In addition, the handheld device then displays 142 the results which it receives from the authorization server.

The method includes a plurality of steps, and can begin by the user starting 130 the secure document application by activating the secure document application on a client device, such as a laptop, and opening a secured document that requires credentials for access. The secure document application detects the need for credentials and contacts 131 the authentication server application to start a new authentication session for the user to begin accessing the document. Thereafter, the authentication server application generates 132 a session ID for the user whereby such session ID will be used through the process to track and ensure proper decryption and authentication. This session ID is transmitted back to the secure document application.
The secure document application 240 creates 133 a multi-dimensional barcode 10 wherein the barcode has dynamic encryption keys, server/portal information, a session ID, and a unique key. The multi-dimensional barcode can be displayed 133 in a separate popup or window.
In one embodiment, the user can enable the online application device 260 to cause the device to scan 137 the barcode displayed. However, it can be appreciated that other techniques of coded transmission including, but not limited to NFC, RFID, Bluetooth, and computer generated sound, can be used without departing from the scope of the invention.
The secure document application is put on hold 134 as it waits for a notification from the authentication server that the session started 130 has been completed and the relevant credentials provided by the online application 135-130.
The user then starts authentication 135 by entering a PIN on the handheld device 260. The online authentication application 280 on the handheld device then validates 136 the PIN and displays a scan option. The user points 137 the handheld device to the barcode generated by the secure document application, clicking the scan option on the handheld device. The user scans the barcode 138 thereby acquiring the credentials request from the secure document application.
The online application or the handheld device finds 139 the encrypted user credentials with the encryption key from the barcode and sends 139 the encrypted credentials and session ID to the authentication server and the authentication server application.
The authentication server checks 140 in the provisioned user database 250, validates the session, and sends the encrypted payload to the waiting secure document application.
After validation, the device displays 142 the result as received from the authentication server. The secure document application decrypts and extracts 141 the credentials from the payload received from the authentication server. The secure document application uses 141 the decrypted credentials to decrypt the document or payload. The encrypted document is now open 143.
FIG. 12 provides an illustration of the separate communication channels in an embodiment of the present invention that can be used for an authentication process. The online application of the handheld device 260 communicates with the authentication server over a first communications channel 90. This channel is separate from a second communications channel 92, over which the secure document application 240 and authentication server 200 communicate. It is contemplated in the art that the invention includes other configurations. For example, communication channels can be different types of communication channels, including systems typically digital, such as phone, internet, and wifi, but also some forms of analog communications. In addition, the applications described herein can communicate through different devices, such as mobile phone to mobile phone, mobile phone to computer, computer to laptop, or mobile phone to tablet, among other things.
Specifically, in one further embodiment of a system and process according to the invention, at least the out-bound portions of communications from the handheld device 260 to the authentication server 200 are provided in a separate communications channel 90 and are out-of-band from the communication channel 92 over which the authentication server 200 and secure document application 240 communicate.
In another embodiment of a system and process according to the invention, at least the out-bound communications channel 90 from the second channel device application 280 to the authentication server are provided in a separate communications channel and are out-of-band from the communication channel 92 over which the authentication server and first channel document application 240 communicate.
Furthermore, another embodiment of a system and process according to the invention, at least the out-bound communications channel from the first channel document application 240 to the authentication server are provided in a separate communications channel 90 and are out-of-band from the communication channel 92 over which the authentication server and second channel device application 280 communicate.
Various changes may be made to the system and process embodying the principles of the invention. The foregoing embodiments are set forth in an illustrative and not in a limiting sense. The scope of the invention is defined by the claims appended hereto.
