Description
BACKGROUND OF THE INVENTION
1. Field of the Invention

The present invention generally relates to systems and methods for generation and use of a device wallet identifier.


2. Description of the Related Art

Electronic or digital wallets often have a number of identifiers—for example, a hardware identifier, an operating system-generated identifier, a platform identifier, etc. These identifiers may also be based on the underlying deice, or from the wallet provider. The number of different identifiers often causes fragmentation and increases the complexity for an issuer to identify wallet providers and device-specific wallets in a uniform manner.


SUMMARY OF THE INVENTION

Systems and methods for using a device wallet identifier are disclosed. In one embodiment, in an information processing apparatus comprising at least one computer processor, a method for generating a device wallet identifier may include: (1) receiving a wallet identifier for an electronic wallet or payment application executed by an electronic device; (2) retrieving an issuer identifier for a customer associated with the electronic wallet or payment application; (3) generating a device wallet identifier; and (4) storing a mapping of the device wallet identifier to the issuer identifier for the customer.


In one embodiment, the wallet identifier may include at least one of a hardware identifier, an operating system-generated identifier, and a platform-generated identifier.


In one embodiment, the step of generating a device wallet identifier may include: selecting a first number from a plurality of prefixes; selecting a second number from a plurality of suffixes; creating a combined number by appending the first number to the second number; and executing a device hash function on the combined number.


In one embodiment, the combined number may also include the wallet identifier and/or the issuer identifier.


In one embodiment, the method may further include removing the first number from the plurality of prefixes, and removing the second number from the plurality of suffixes.


In one embodiment, the device wallet identifier may also include a timestamp.


In one embodiment, the device wallet identifier may not be reversible or replicable.


According to another embodiment, a system for generating a device wallet identifier may include an electronic device executing an electronic wallet or payment application and a backend comprising at least one computer processor. The backend may receive a wallet identifier for the electronic wallet or payment application from the electronic device; may retrieve an issuer identifier for a customer associated with the electronic wallet or payment application; may generate a device wallet identifier; and may store a mapping of the device wallet identifier to the issuer identifier for the customer.


In one embodiment, the wallet identifier may include at least one of a hardware identifier, an operating system-generated identifier, and a platform-generated identifier.


In one embodiment, the backend may generate the device wallet identifier by: selecting a first number from a plurality of prefixes; selecting a second number from a plurality of suffixes; creating a combined number by appending the first number to the second number; and executing a device hash function on the combined number.


In one embodiment, the combined number may also include the wallet identifier and/or the issuer identifier.


In one embodiment, the backend may also remove the first number from the plurality of prefixes, and remove the second number from the plurality of suffixes.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

Embodiments disclosed herein are directed to systems and methods for generation and use of a device wallet identifier.


Embodiments disclosed herein may create a onetime mapping of the hardware identifier, operating system-generated identifier, and/or platform-generated identifier to a device wallet identifier, which may be called “DeviceWalletId.” The device wallet identifier may be a unique alphanumeric string that may not be reversible and/or replicable.


The device wallet identifier may be generated using a combination of an issuer identifier (e.g., something that uniquely identifies the customer/user on the issuer side, such as a person identifier, customer identifier, profile identifier, etc.) and/or a hardware identifier, which may be passed to an algorithmic function and mapped, by the issuer, to the issuer identifier.


Embodiments may provide some or all of the following advantages: (1) unified handling of permutation of the hardware identifier, operating system-generated identifier, and/or platform-generated identifier and the issuer identifier; (2) provides an immutable identifier that survives events involving the wallet or device (e.g., resets, uninstalls, operating system resets, etc.), thereby “hack-proofing” the hardware identifier if the device is compromised (e.g., jail broken); (3) the issuer may maintain a device history that may be used for fraud detection, decisioning, etc.; (4) allows multiple people using the same device (e.g., the same hardware identifier, operating system-generated identifier, and/or platform-generated identifier) to have different device wallet identifiers based on different issuer identifiers; (5) permits promotions, communications, offers, etc. to be sent to the customer based on usage and/or usage patterns; etc.


Referring to FIG. 1, a system for generation and use of a device wallet identifier is disclosed according to one embodiment. System 100 may include electronic device 110, which may be any suitable electronic device (e.g., smartphone, tablet computer, smart watch, Internet of Things (IoT) appliance, notebook/laptop computer, desktop computer, workstation, etc.). Electronic device 110 may execute operating system 112, and may execute one or more electronic wallets 114, one or more payment application 116, etc.


Electronic device 110 may provide one or more of a hardware identifier (e.g., a manufacturer defined or assigned identifier), operating system-generated identifier, and/or platform-generated identifier for electronic wallet(s) 114 and/or payment application(s) 116.


System 100 may further include issuer 120, which may issue one or more financial instruments that may be provisioned to electronic wallet(s) 114 and/or payment application(s) 114. Issuer 120 may include backend 122, which may include one or more servers, computers, etc. that may generate a device wallet identifier.


Issuer 120 may also assign an issuer identifier (e.g., something that uniquely identifies the customer on the issuer side, such as a person identifier, customer identifier, profile identifier, etc.) to customer 130.


Storage 124 may maintain a mapping between the issuer identifier and the device wallet identifier.


In one embodiment, the device wallet identifier may be stored on electronic device 110, for example, in secure storage, within a cache for electronic wallet 114 and/or payment application, etc. In one embodiment, the device wallet identifier may be sent as part of a request or API call from electronic device 110 to issuer backend 122.


Referring to FIG. 2, a method for generating a device wallet identifier is disclosed according to one embodiment.


In step 205, a backend for an issuer may receive a payload including, for example, a wallet identifier that may include one or more of a hardware identifier, operating system-generated identifier, and/or platform-generated identifier for an electronic wallet or payment application executed by an electronic device. In one embodiment, this may occur when a financial instrument is provisioned to the wallet, during a lifecycle event, etc.


In one embodiment, at least some of the payload may be encrypted.


In another embodiment, at least some of the payload may be received from a payment network (e.g., Visa, MasterCard, etc.) during provisioning. In one embodiment, a reconciliation algorithm may be used to calculate a device wallet identifier.


In step 210, the backend may retrieve an issuer identifier for the customer. In one embodiment, the issuer identifier may be anything that uniquely identifies the customer on the issuer side, such as a person identifier, customer identifier, profile identifier, etc.


In step 215, the backend may generate a device wallet identifier. In one embodiment, the device wallet identifier may be based on the wallet identifier (e.g., the hardware identifier, operating system-generated identifier, and/or platform-generated identifier) and the issuer identifier using an algorithmic function. In one embodiment, the device wallet identifier that be a unique alphanumeric string that may not be reversible and/or replicable.


In one embodiment, the device wallet identifier may be unique to the customer, even if the customers are using the same device.


In another embodiment, the device wallet identifier may be randomly generated. For example, a first table of sequential numbers having a fixed length may be used. For example, the first table may have four digits. Any suitable number of digits may be used as is necessary and/or desired.


In one embodiment, the first table may lists the number of identifier batches intended to be used by an application.


An example of a first table is provided in FIG. 3A.


A second table of random numbers having a fixed length that may be left padded with zeros may be used. In one embodiment, a table having six digits may be used. Any suitable number of digits may be used as is necessary and/or desired.


In one embodiment, the second table may be is an estimate of the quantity of identifiers allocated in a given batch.


An example of a second table is provided in FIG. 3B.


Next, a hash of the device identifier may be generated using the first and second tables. Referring to FIG. 4, a method of deriving a Device Wallet ID is disclosed according to one embodiment.


In step 405, a number, X, may be selected. In one embodiment, this may be an available ID_PREFIX value from the first table (e.g., the DEVICE_ID_PREFIX table). The selected ID_PREFIX may be marked as unavailable. In one embodiment, the number X may be randomly or pseudo-randomly selected.


In step 410, a second number, Y, may be selected. In one embodiment, an available ID_SUFFIX value from the second table (e.g., the DEVICE_ID_SUFFIX table) may be selected and may be marked as unavailable. In one embodiment, the number Y may be randomly or pseudo-randomly selected.


In step 415, the two values (X and Y) may be appended and passed as a parameter into a Device Hash algorithm. In one embodiment, additional parameter(s), such as such as a person identifier, a customer identifier, a profile identifier, a hardware identifier, etc. may be appended with the two values as is necessary and/or desired.


In one embodiment, a system time stamp (e.g., in milliseconds) may be appended and passed to the Device Hash function.


The derived value is the DeviceWalletID. For example, an equation representing the DeviceWalletID is

DeviceWalletID=DeviceHashAlgorithm(“X”+“Y”,“ProfileID”).


An example table depicting DEVICE_HASH (e.g., the Device Wallet ID) is provided as FIG. 3C.


In step 220, the device wallet identifier may be mapped to the issuer identifier for the customer, and may be stored in a database. In one embodiment, the device wallet identifier may also be calculated at runtime.


Exemplary use cases for the device wallet identifier are as follows. First, the device wallet identifier may be used to send special offers based on customers' usage pattern to encourage people to use the wallet or payment application. For example, customers may be provided with incentives to encourage continued use (e.g., “super users” that frequently use the wallet or payment application), to encourage continued use (e.g., casual users that use the application occasionally), or to encourage users to try the wallet or payment application (e.g., first time users).


As another example, the device wallet identifier may be used to profile a customer's behavior using the wallet or payment application on the electronic device. For example, a profile may be generated based on the type of transactions, number of transactions, transaction amount, etc. conducted by the customer using the wallet or payment application on the electronic device. A separate profile may be kept for each wallet or payment application on each of the customer's electronic devices.


As another example, the device wallet identifier may be used to provide analytics for customers. For example, the customer may be provided with the customer's behavior pattern using each of the customer's wallets payment applications on each of the customer's electronic devices.


As another example, the device wallet identifier may be used with a fraud rules engine to approve/reject the transactions based on the geographic coordinates of the electronic device and the device wallet identifier, to calculate a risk score based on the type of transactions/payment activities on the electronic device, etc.


In one embodiment, the device wallet identifier may be used to send targeted marketing messages, notifications, personalized messages, etc. to the customer through the wallet or payment application, out of band, etc.


It should be recognized that although several embodiments have been disclosed, these embodiments are not exclusive and aspects of one embodiment may be applicable to other embodiments.
