Identity verification through multisystem cooperation

Abstract

A system includes first and second subsystems. The first subsystem receives a validation number request, transmitted by a first device in response to the entry of an account number into a first field of a webpage. In response to receiving the request, the first subsystem randomly generates the validation number, stores a copy in memory, and transmits it to a second device. The second subsystem receives a transaction request that includes the validation number from the first device, and transmits the received number to the first subsystem. The first device transmitted the request in response to the second device receiving the validation number and its subsequent entry into a second field of the webpage displayed on the first device. In response to receiving the validation number, the first subsystem determines that it matches the stored copy and transmits a message to the second subsystem authorizing the transaction.

Description

TECHNICAL FIELD

The present disclosure relates generally to multisystem data transferring and, more specifically, to identity verification through multisystem cooperation.

BACKGROUND

The internet has enabled individuals to interact with organizations and other entities without ever stepping foot inside the physical buildings operated by the entities. For example, an individual may provide information to an entity simply by entering the information into a form displayed on a webpage belonging to the entity or otherwise transmitting the information electronically to the entity.

SUMMARY

This disclosure contemplates an identity verification system that may be used to help verify the identity of a user who is providing electronic information to an entity system. In particular, the disclosed system may be used to verify a user's identity when the user is attempting to engage in an electronic transaction with an entity system by using an internet-connected device to provide account information to the entity system. When the user enters an account number into a field displayed on a webpage of the entity, a system associated with the institution at which the user's account is held generates a validation number for the transaction. The institution system then transmits this validation number to a second device, which the user/account holder had previously registered with the system. After receiving the validation number on his/her second device, the user enters the validation number into the webpage displayed on his/her first device and transmits it to the entity system as part of the user's transaction request. The entity system then provides the validation number that it received from the user back to the institution system for authentication. If the validation number received by the institution system matches the validation number that the institution system originally transmitted to the second device, the institution system determines that the user who is attempting to conduct the transaction with the entity system is in fact the account holder (as opposed to an individual who has obtained the account holder's information and is attempting to impersonate the account holder), and instructs the entity system to approve the requested transaction. On the other hand, if the received validation number does not match the validation number originally transmitted by the institution system to the second device, the institution system instructs the entity system to decline the requested transaction. An embodiment of the identity verification system is described below.

According to one embodiment, a system includes a first subsystem associated with an institution and a second subsystem associated with an entity. The first subsystem includes a memory and a hardware processor communicatively coupled to the memory. The second subsystem includes a hardware processor. The hardware processor of the first subsystem receives, from a first user device, a request for a validation number. The first user device transmitted the request for the validation number in response to a determination that an account number had been entered into a first field of a webpage displayed on the first user device. The webpage is associated with the entity. The account number corresponds to an account held at the institution. In response to receiving the request for the validation number, the processor of the first subsystem randomly generates the validation number. The processor of the first subsystem also stores a copy of the validation number in the memory. The processor of the first subsystem additionally transmits the validation number to a second user device associated with the account. The hardware processor of the second subsystem receives, from the first user device, a request for a transaction. The request for the transaction includes the validation number. The first user device transmitted the request for the transaction in response to the second user device receiving the validation number and the validation number being entered into a second field of the webpage displayed on the first user device. The processor of the second subsystem also transmits the validation number received in the request for the transaction to the first subsystem. In response to receiving the validation number, the hardware processor of the first subsystem determines that the validation number received from the second subsystem matches the copy of the validation number stored in the memory. In response to determining that the validation number received from the second subsystem matches the copy of the validation number stored in the memory, the processor of the first subsystem transmits a message to the second subsystem authorizing the transaction.

Certain embodiments provide one or more technical advantages. As an example, an embodiment includes a mobile device application that, in response to the mobile device receiving a validation number, is configured to automatically display a pop-up notification of the validation number on the mobile device display. In this manner, the embodiment enables a user of the mobile device to efficiently access the validation number, and conserves processing resources that would otherwise be expended by the user using his/her mobile device to navigate to the mobile application and accessing the validation number within the mobile application. As another example, in certain embodiments, a user device is configured to determine when a user has entered an account number into a field displayed on a webpage and, in response, automatically replace the account verification fields traditionally displayed on the webpage with a field for input of a validation number. In this manner, certain embodiments conserve the processing and networking resources that would otherwise be expended by (1) the device transmitting the account number and the traditional account verification data to a merchant system, (2) the merchant system determining that the account number belongs to an institution for which the user should transmit a validation number to the merchant system, and (3) the merchant system transmitting a request to the user's device to display a field for input of the validation number. The system described in the present disclosure may particularly be integrated into a practical application of an identity verification system for use by an institution that conducts electronic transactions on behalf of its account holders, who initiate the transactions by providing account details to entities through webpages belonging to the entities.

Certain embodiments may include none, some, or all of the above technical advantages. One or more other technical advantages may be readily apparent to one skilled in the art form the figures, descriptions, and claims included herein.

DETAILED DESCRIPTION

Embodiments of the present disclosure and its advantages may be understood by referring to FIGS. 1 through 2B of the drawings, like numerals being used for like and corresponding parts of the various drawings.

I. System Overview

FIG. 1 illustrates an example identity verification system 100 that includes first device 102, user 104, second device 106, network 108, entity system 110, and institution system 112. Entity system 110 is associated with an entity with which user 104 may conduct a transaction. Institution system 112 is associated with an institution at which user 104 holds an account that user 104 may use to conduct the transaction. Generally, when user 104 attempts to engage in a transaction with entity system 110 using first device 102, institution system 112, entity system 110, first device 102, and second device 106 act cooperatively to verify the identify of user 104, with the aid of a validation number 130, generated by institution system 112 for the transaction. While described throughout this disclosure as being a number, validation number 130 may be any suitable sequence of characters. For example, in certain embodiments, validation number 130 may be an alphanumeric number, or any other suitable sequence of characters. Details of the manner by which validation number 130 is generated and subsequently used by first device 102, second device 106, entity system 110, and institution system 112 to confirm the identity of user 104 are presented below, and in the discussion of FIGS. 2A and 2B.

First device 102 and second device 106 are used by user 104 to communicate with components of system 100 over network 108. As illustrated in FIG. 1, in certain embodiments first device 102 and second device 106 are separate devices. In some embodiments, first device 102 and second device 106 are the same device. For example, first device 102 and second device 106 may both correspond to a smart phone operated by user 104.

First device 102 includes display 114. First device 102 is configured to display a webpage 116 belonging to entity system 110 on display 114. For example, user 104 may use first device 102 to access a web browser installed on first device 102 and use the web browser to navigate to webpage 116. Webpage 116 is an interactive webpage through which user 104 may initiate a transaction with entity system 110. For example, user 104 may use webpage 116 to purchase one or more goods from the entity associated with entity system 110. As illustrated in FIG. 1, webpage 116 may display one or more fields 140a/b. For example, webpage 116 may display a first field 140a for input of an account number 136, and a second field 140b for input of a validation number 130. While illustrated in FIG. 1 as including two fields 140a/b, webpage 116 may display any number of fields 140a/b. Furthermore, in certain embodiments, webpage 116 may be configured to adjust the number of displayed fields 140a/b in response to receiving input from user 104. For example, in certain embodiments, when webpage 116 first loads, webpage 116 may be configured to display a set of fields 140a/b that includes a field for input of a credit/bank card number, a field for input of an expiry date of the credit/bank card, and a field for input of a card verification value (CVV) number. Then, in response to user 104 entering a credit/bank card number that is associated with institution system 112, device 102 may be configured to replace the field for input of the expiry date of the credit/bank card and the field for input of the CVV number with a field 140b for input of a validation number 130.

In response to user 104 entering an account number 136 that is associated with institution system 112 into first field 140a, first device 102 is configured to transmit transaction initiation message 138 to institution system 112. As described in further detail below, and in the discussion of FIGS. 2A and 2B, transaction initiation message 138 is used by first device 102 to request that institution system 112 generate a validation number 130 for the transaction that user 104 is initiating. First device 102 may be configured to determine that user 104 has entered an account number 136 that is associated with institution system 112 into field 140a in any suitable manner. For example, in certain embodiments, device 102 is configured to make this determination based on the first four numbers of account number 136. In response to user 104 entering a validation number 130 into second field 140b, first device 102 is configured to transmit transaction request 144 to entity system 110. Transaction request 144 includes account number 136 and validation number 130. As described in further detail below, and in the discussion of FIGS. 2A and 2B, entity system 110 uses the information transmitted in transaction request 144 to verify user 104's identity and to process the requested transaction.

First device 102 includes any appropriate device for displaying webpage 116 and for communicating with components of system 100 over network 108. For example, first device 102 may be a mobile phone, a computer, a laptop, a tablet, an IoT device, and/or an automated assistant, among others. In addition to including display 114, first device 102 may include any other appropriate user interface, such as a microphone, keypad, or other appropriate terminal equipment usable by user 104. In some embodiments, an application executed by a processor of first device 102 may perform the functions described herein.

Second device 106 is configured to receive validation number 130 from institution system 112 and present validation number 130 to user 104. Second device 106 may be configured to receive and present validation number 130 to user 104 in any suitable manner. As an example, in certain embodiments, an application installed on second device 106 is configured to receive validation number 130 from institution system 112 and to present validation number 130 to user 104. For example, the application may be configured to automatically generate a pop-up notification 142 that includes validation number 130 on the display 107 of second device 106. In some embodiments, second device 106 may automatically turn on display 107 in order to present pop-up notification 142 to user 104. In this manner, second device 106 may display validation number 130 to user 104 even though user 104 is not actively operating second device 106. In certain embodiments, second device 106 may be configured to display pop-up notification 142 to user 104 for a set amount of time, after which validation number 130 may no longer be available to user 104. In some embodiments, user 106 may be able to view validation number 130 even after pop-up notification 142 has disappeared from display 107. For example, in such embodiments, user 104 may view validation number 130 by navigating to the application that generated pop-up notification 142 and viewing validation number 130 within the application. As another example of the manner by which second device 106 may present validation number 130 to user 104, in certain embodiments, second device 106 may receive validation number 130 from institution system 112 in an SMS message or any other electronic message (e.g., email), and present the electronic message to user 104 on display 107. As a further example, in certain embodiments in which second device 106 is the same device as first device 102, in response to receiving validation number 130 from institution system 112, second device 106 may be configured to automatically populate second field 140b, displayed on webpage 116, with validation number 130.

Second device 106 includes any appropriate mobile device for displaying validation number 130 to user 104, and for communicating with components of system 100 over network 108. For example, second device 102 may be a mobile phone, a laptop, a tablet, an IoT device, and/or an automated assistant, among others. In addition to including display 107, second device 102 may include any other appropriate user interface, such as a microphone, keypad, or other appropriate terminal equipment usable by user 104. In some embodiments, an application executed by a processor of second device 106 may perform the functions described herein.

Network 108 facilitates communication between and amongst the various components of system 100. This disclosure contemplates network 108 being any suitable network operable to facilitate communication between such components. Network 108 may include any interconnecting system capable of transmitting audio, video, signals, data, messages, or any combination of the preceding. Network 108 may include all or a portion of a public switched telephone network (PSTN), a public or private data network, a local area network (LAN), a metropolitan area network (MAN), a wide area network (WAN), a local, regional, or global communication or computer network, such as the Internet, a wireline or wireless network, an enterprise intranet, or any other suitable communication link, including combinations thereof, operable to facilitate communication between the components.

Entity system 110 is associated with a given entity with which user 104 is attempting to engage in a transaction. For example, entity system 110 may belong to a merchant with an online store, and/or any other entity with which user 104 may attempt to engage in a transaction. As illustrated in FIG. 1, entity system 110 includes a processor 118 and a memory 120. This disclosure contemplates processor 118 and memory 120 being configured to perform any of the functions of entity system 110 described herein. For example, processor 118 may execute instructions 122 stored in memory 120 to perform any of the functions described herein. Generally, entity system 110 is configured to: (1) receive a transaction request 144 from first device 102 that includes a validation number 130; (2) provide the received validation number 130 to institution system 112 for authentication; (3) receive an authentication result 148 back from institution system 112, indicating whether or not the validation number 130 received from first device 102 matches the validation number 130 stored by institution system 112; and (4) approve or decline transaction request 144 based on authentication result 148. These functions of entity system 110 are described in further detail below, in the discussion of FIGS. 2A and 2B.

Processor 118 is any electronic circuitry, including, but not limited to central processing units (CPUs), graphics processing units (GPUs), microprocessors, application specific integrated circuits (ASIC), application specific instruction set processor (ASIP), and/or state machines, that communicatively couples to memory 120 and controls the operation of entity system 110. Processor 118 may be 8-bit, 16-bit, 32-bit, 64-bit or of any other suitable architecture. Processor 118 may include an arithmetic logic unit (ALU) for performing arithmetic and logic operations, processor registers that supply operands to the ALU and store the results of ALU operations, and a control unit that fetches instructions from memory and executes them by directing the coordinated operations of the ALU, registers and other components. Processor 118 may include other hardware and software that operates to control and process information. Processor 118 executes software, such as instructions 122, stored on memory to perform any of the functions described herein. Processor 118 controls the operation and administration of entity system 110 by processing information received from first device 102, second device 106, network 108, and/or institution system 112. Processor 118 may be a programmable logic device, a microcontroller, a microprocessor, any suitable processing device, or any suitable combination of the preceding. Processor 118 is not limited to a single processing device and may encompass multiple processing devices. In certain embodiments in which processor 118 encompasses multiple processing devices, such devices may be located at geographically separate locations from one another and connected to one another by a network (e.g., network 108).

Memory 120 may store, either permanently or temporarily, data, operational software, or other information for processor 118, such as instructions 122. Memory 120 may include any one or a combination of volatile or non-volatile local or remote devices suitable for storing information. For example, memory 120 may include random access memory (RAM), read only memory (ROM), magnetic storage devices, optical storage devices, or any other suitable information storage device or a combination of these devices. The software represents any suitable set of instructions, logic, or code embodied in a computer-readable storage medium. For example, the software may be embodied in memory 120, a disk, a CD, or a flash drive. In particular embodiments, the software may include an application, such as instructions 122, executable by processor 118 to perform one or more of the functions described herein.

Institution system 112 is associated with a given institution at which user 104 holds an account that the user may use to complete a transaction with entity system 110. For example, institution system 112 may belong to a bank, a credit card company, and/or any other financial institution with which user 104 may hold an account. As illustrated in FIG. 1, institution system 112 includes a processor 124 and a memory 126. This disclosure contemplates processor 124 and memory 126 being configured to perform any of the functions of institution system 112 described herein. For example, processor 124 may execute instructions 128 stored in memory 126 to perform any of the functions described herein. Generally, institution system 112 is configured to: (1) receive transaction initiation message 138 from first device 102, indicating that user 104 is attempting to initiate a transaction with entity system 110; (2) in response to receiving transaction initiation message 138, randomly generate a validation number 130 for the transaction; (3) store a copy of validation number 130 in memory 126; (4) transmit validation number 130 to second device 106; (5) receive an authentication request 146 from entity system 110, which includes a validation number 130 received by entity system 110 from first device 102; (6) compare the received validation number 130 with the copy of the validation number 130 stored in memory 126; and (7) transmit a message 148 to entity system 110 instructing entity system 110 to approve or decline transaction request 144, based on the results of the comparison. These functions of institution system 112 are described in further detail below, in the discussion of FIGS. 2A and 2B.

Processor 124 is any electronic circuitry, including, but not limited to central processing units (CPUs), graphics processing units (GPUs), microprocessors, application specific integrated circuits (ASIC), application specific instruction set processor (ASIP), and/or state machines, that communicatively couples to memory 126 and controls the operation of institution system 112. Processor 124 may be 8-bit, 16-bit, 32-bit, 64-bit or of any other suitable architecture. Processor 124 may include an arithmetic logic unit (ALU) for performing arithmetic and logic operations, processor registers that supply operands to the ALU and store the results of ALU operations, and a control unit that fetches instructions from memory and executes them by directing the coordinated operations of the ALU, registers and other components. Processor 124 may include other hardware and software that operates to control and process information. Processor 124 executes software, such as instructions 128, stored on memory to perform any of the functions described herein. Processor 124 controls the operation and administration of institution system 112 by processing information received from first device 102, second device 106, network 108, and/or entity system 110. Processor 124 may be a programmable logic device, a microcontroller, a microprocessor, any suitable processing device, or any suitable combination of the preceding. Processor 124 is not limited to a single processing device and may encompass multiple processing devices. In certain embodiments in which processor 124 encompasses multiple processing devices, such devices may be located at geographically separate locations from one another and connected to one another by a network (e.g., network 108).

Memory 126 may store, either permanently or temporarily, data, operational software, or other information for processor 124, such as instructions 128. Memory 126 may include any one or a combination of volatile or non-volatile local or remote devices suitable for storing information. For example, memory 126 may include random access memory (RAM), read only memory (ROM), magnetic storage devices, optical storage devices, or any other suitable information storage device or a combination of these devices. The software represents any suitable set of instructions, logic, or code embodied in a computer-readable storage medium. For example, the software may be embodied in memory 126, a disk, a CD, or a flash drive. In particular embodiments, the software may include an application, such as instructions 128, executable by processor 124 to perform one or more of the functions described herein.

Memory 126 also stores copies of the validation numbers 130a through 130n that have been generated by institution system 112. In certain embodiments, memory 126 stores copies of the validation numbers that it has generated and that are outstanding. For example, memory 126 stores copies of the validation numbers that institution system 112 has not yet received back from entity system 110 in authentication requests 146. In some embodiments, memory 126 stores a full set of historical validation numbers 130a through 130n (e.g., copies of both the outstanding validation numbers 130 and those validation numbers 130 that institution system 112 has received back from entity system 110 in authentication requests 146). Institution system 112 may use this full set of historical validation numbers 130a through 130n to help ensure that any new validation numbers 130 that it generates have not previously been used for identity verification purposes, as described in further detail below, in the discussion of FIGS. 2A and 2B.

In certain embodiments, memory 126 also stores a set of times 132 and a set of account details 134. Each time of the set of times 132 is associated with a validation number 130, and corresponds to the time at which the validation number was generated by institution system 112. In certain embodiments, validation numbers 130 may expire after a certain amount of time. In such embodiments, institution system 112 uses set of times 132 to determine whether or not a validation number 130 received in an authentication request 146 has expired, as described in further detail below, in the discussion of FIGS. 2A and 2B. In certain embodiments, for each user 104 who holds an account with the institution associated with institution system 112, account details 134 stores information about the user and/or his/her account. For example, for a given user 104, account details 134 may store the account number 136 assigned to the user's account as well as an identification of second device 106, to which institution system 112 should send validation numbers 130, and/or any other information that institution system 112 may use to transmit validation numbers 130 to second device 106. For example, account details 134 may include a cell phone number assigned to second device 106, an email address belonging to user 104, and/or any other suitable identification information that may be used to transmit validation number 130 to second device 106.

Modifications, additions, or omissions may be made to the systems described herein without departing from the scope of the invention. For example, system 100 may include any number of users 104, first devices 102, second devices 106, entity system 110, and institution systems 112. The components may be integrated or separated. Moreover, the operations may be performed by more, fewer, or other components. Additionally, the operations may be performed using any suitable logic comprising software, hardware, and/or other logic.

FIGS. 2A and 2B present a flowchart (described in conjunction with elements of FIG. 1) illustrating an example method 200 by which first device 102, second device 106, institution system 112, and entity system 110 act cooperatively to verify the identify of a user 104 who is attempted to engage in a transaction with entity system 110.

In step 202 first device 102 determines whether or not user 104 has entered an account number 136 into a field 140a of a webpage 116 associated with entity system 110. If, in step 202 first device 102 determines that user 104 has entered an account number 136 into field 140a, in step 204 first device 102 transmits a message 138 to institutions system 112 requesting that institution system 112 generate a validation number 130. In step 206 institution system 112 randomly generates a validation number 130. Institution system 112 may randomly generate validation number 130 in any suitable manner. As an example, in certain embodiments in which validation number 130 corresponds to a sequence of numerical digits, institution system 112 may generate validation number 130 using a random number generator stored in memory 126. For example, institution system 112 may use the random number generator to generate a validation number 130 that is 5 digits in length, 10 digits in length, or any other suitable length. In some embodiments, institution system 112 may use the random number generator to randomly generate a length for the validation number as well as to randomly generate the digits that make up the validation number. In certain embodiments in which validation number 130 is an alphanumeric number, institution system 112 may use the random number generator to: (1) randomly determine a length for the validation number; (2) randomly determine a number of letters to include in the validation number, randomly determine those letters, and randomly assign each of those letters to a position within the validation number; (3) randomly determine a number of digits to include in the validation number, randomly determine those digits, and randomly assign each of those digits to a position within the validation number; and/or (4) randomly determine a number of wildcard characters to include in the validation number, randomly determine those wildcard characters, and randomly assign each of those wildcard characters to a position within the validation number.

In step 208 institution system 112 compares the randomly generated validation number 130 to historical validation numbers 130a through 130n stored in memory 120 to determine whether or not the validation number 130 already exists. If, in step 208 institution system 112 determines that validation number 130 already exists in memory 126, method 200 returns to step 206, where institution system 112 randomly generates a new validation number 130. If, in step 208 institution system 112 determines that validation number 130 does not already exist in memory 126, in step 210 institution system 112 transmit validation number 130 to second device 106. In step 212 second device 106 displays validation number 130 to user 104 on display 107. In response to second device 106 displaying validation number 130, user 104 may enter validation number 130 into a second field 140b of the webpage 116 that is displayed on first device 102.

In step 214 first device 102 determines whether user 104 has entered validation number 130 into second field 140b of webpage 116. If, in step 214 first device 102 determines that user 104 has entered validation number 130 into second field 140b, in step 216 first device 102 transmits validation number 130 to entity system 110 in transaction request 144. In step 218 entity system 110 determines whether or not it has received validation number 130. If, in step 218 entity system 100 determine that it has received validation number 130, in step 220 entity system 110 transmits the received validation number 130 to institution system 112 for authentication.

In step 222 institution system 112 determines whether or not the validation number 130 received from entity system 110 matches the copy of the original validation number 130 that institution system 112 transmitted to second device 106. In certain embodiments, institution system 112 additionally determines whether or not it has received the validation number within a threshold amount of time since it first generated the validation number (e.g., whether or not the validation number has expired). If, in step 222 institution system 112 determines that the validation number 130 received from entity system 110 does not match the copy of the validation number 130 stored in memory 126 and/or that the validation number 130 has been received after the threshold amount of time since it was first generated, in step 226 institution system 112 generates message 148 instructing entity system 110 to decline user 104's transaction request 144. If, in step 222 institution system 112 determines that the validation number 130 received from entity system 110 matches the copy of the validation number 130 stored in memory 126 and, in certain embodiments, that the validation number 130 was received within the threshold time since its creation, in step 224 institution system generates message 148 instructing entity system 110 to approve user 104's transaction request 144. In step 228 institution system 112 transmits message 148 to entity system 110. In certain embodiments, in step 230 institution system 112 also sends instructions to second device 106 to delete any copies of validation number 130, such that validation number 130 is no longer available on second device 106. In response to receiving such instructions, second device 102 deletes validation number 130, in step 232. In step 234 entity system 110 transmits transaction result message 142 to first device 102. Transaction result message 142 may include any suitable information. As an example, in certain embodiments in which institution system 112 transmitted an authentication result message 148 to entity system 110 instructing entity system 110 to deny the requested transaction, transaction result message 142 may indicate that entity system 110 has denied the transaction. As another example, in certain embodiments in which institution system 112 transmitted an authentication result message 148 to entity system 110 instructing entity system 110 to approve the transaction request 144, entity system 110 may have used account number 136 to process the transaction. In such embodiments, transaction result message 142 may indicate that entity system has processed the transaction, and may include information such as a confirmation number. In step 236, in response to receiving transaction result message 142, first device 102 displays the contents of transaction result message 142 on display 114. For example, first device 102 may display a message to user 104 on display 114 indicating that entity system 110 has approved or declined the transaction.

Modifications, additions, or omissions may be made to method 200 depicted in FIGS. 2A and 2B. Method 200 may include more, fewer, or other steps. For example, steps may be performed in parallel or in any suitable order. While discussed as first device 102, second device 106, institution system 112, and entity system 110 (or components thereof) performing certain steps, any suitable components of system 100, may perform one or more steps of the method.
