BLOCKCHAIN BASED BANKING IDENTITY AUTHENTICATION

Abstract

Systems and methods are disclosed for interacting with a blockchain and users of the blockchain to perform banking identity authentication services. For example, a method may include receiving a bank transaction from a participant; verifying the bank transaction; generating and communicating a confirmation that the bank transaction is valid to the participant; adding the bank transaction to a block of bank transactions; generating a cryptographic hash for the block of bank transactions; solving a cryptographic puzzle involving the hash of the block of bank transactions; adding the block to the blockchain; and/or transmitting the solution to the cryptographic puzzle, and the block of bank transactions to another participant. Otherwise, if the identity data is not valid, generating and communicating the confirmation that the bank transaction is not valid to the participant.

Description

TECHNICAL FIELD

The present disclosure relates to using and accessing data stored in a blockchain. In particular, systems and methods are disclosed for interacting with the blockchain and users of the blockchain to perform banking identity authentication services.

BACKGROUND

In the business world an interaction between a business and a customer, or the business and another business, typically requires validation of one or more pieces of information before a transaction can take place. This validation is often achieved by the participants involved in the interaction contacting a central authority that is a trusted source of truth for the particular piece of information. The central authority may then validate, or not validate the particular piece of information and communicate its findings to the participants. Based upon the validation, or lack of validation, a consensus among the participants is formed and assuming the information is valid the transaction between the participants may take place, and subsequently be recorded. Similar issues arise between citizens and their governments, and businesses and governments.

Traditionally, businesses, customers, and central authorities have stored information related to transactions, and records of transactions, in databases, or ledgers which have been used in accounting to track transactions and information related to those transactions. Often these databases or ledgers held by the participants must be reconciled to achieve consensus as to the validity of the information stored in the databases and ledgers. Alternatively, as described above the central authority may be responsible for determining the validity of information stored in a database or a ledger and functioning as an arbiter of consensus for interested parties.

A blockchain is a new way of achieving a distributed consensus on the validity or invalidity of information. As opposed to using a central authority, a blockchain is a distributed database or ledger, in which a transactional record is maintained at each node of a peer to peer network. Commonly, the distributed ledger is comprised of groupings of transactions bundled together into a “block.” When a change to the distributed ledger is made (e.g., when a new transaction and/or block is created), each node must form a consensus as to how the change is integrated into the distributed ledger. Upon consensus, the agreed upon change is pushed out to each node so that each node maintains an identical copy of the updated distributed ledger. Any change that does not achieve a consensus is ignored. Accordingly, unlike a traditional system which uses a central authority, a single party cannot unilaterally alter the distributed ledger. This inability to modify past transactions lead to blockchains being generally described as trusted, secure, and/or immutable.

Blockchains are typically deployed in an open, decentralized, and permissionless manner meaning that any party may view information, submit new information, or join the blockchain as a node responsible for confirming information. This open, decentralized, and permissionless approach to a blockchain has limitations. As an example, these blockchains may not be good candidates for interactions that require information to be kept private, or for interactions that require all participants to be vetted prior to their participation.

DETAILED DESCRIPTION

The present embodiments relate to, inter alia, systems and methods for using a blockchain to perform services related to banking, identity management, and insurance applications. The systems and methods described herein allow for using a blockchain which gives the option for private information, and permissioned participants in the blockchain. In particular, the systems and methods allow for a distributed consensus amongst businesses, consumers, and authorities, as to the validity of information and transactions stored on the blockchain. The businesses, authorities, and consumers may all be considered participants in the blockchain network. For example, businesses (e.g., banks, financial institutions, insurers), and their customers, as well as regulators, may all be participants in the blockchain network, which may be open and permissionless, or closed and permissioned. Each of these participants may maintain nodes that are part of the blockchain network, but may also maintain their own systems and networks that may interface with the blockchain network.

Some exemplary, but not limiting, applications that may take advantage of the disclosed systems and methods include specific applications directed to banking, mutual funds, and insurance. These examples relate to problems surrounding money transfers, digital identities, and collective reporting. Specifically, such applications may be: identity authentication, account funding and distribution, card activation, actions trigged by death registry, using and accessing asset data lien perfection obtaining settlement values contractor ratings/evaluations single view of customer's products, associate licensing, using and accessing user data, blockchain based payments, interest validation, industry reporting, agent sales data fund transfers, unclaimed property, auditing and compliance, policy delivery and interaction, and exercising riders and form/rate filing.

The above listed examples, and disclosed systems and methods, may use an application of distributed ledgers, where each new block may be cryptographically linked to the previous block in order to form a “blockchain.” More particularly, to create a new block, each transaction within a block may be assigned a hash value (i.e., an output of a cryptographic hash function, such as SHA-256 or MD5). These hash values may then be combined together utilizing cryptographic techniques (e.g., a Merkle Tree) to generate a hash value representative of the entire new block, and consequently the transactions stored in the block. This hash value may then be combined with the hash value of the previous block to form a hash value included in the header of the new block, thereby cryptographically linking the new block to the blockchain. To this end, the precise value utilized in the header of the new block is dependent on the hash value for each transaction in the new block, as well as the hash value for each transaction in every prior block.

According to certain aspects disclosed herein, information stored in blockchains can be trusted, because the hash value generated for the new block and a nonce value (an arbitrary number used once) are used as inputs into a cryptographic puzzle. The cryptographic puzzle may have a difficulty set by the nodes connected to the blockchain network, or the difficulty may be set by administrators of the blockchain network. In one example of the cryptographic puzzle, a solving node uses the hash value generated for the new block and repeatedly changes the value of the nonce until a solution for the puzzle is found. For example, finding the solution to the cryptographic puzzle may involve finding the nonce value that meets certain criteria (e.g., the nonce value begins with five zeros).

When a solution to the cryptographic puzzle is found, the solving node publishes the solution and the other nodes then verify that the solution is the correct solution. Because the solution also depends on the particular hash values for each transaction within the blockchain, if the solving node attempted to modify any transaction, the solution would not be verified by the other nodes. More particularly, if a single node attempts to modify a prior transaction within the blockchain, a cascade of different hash values are generated for each tier of the cryptographic combination technique. This results in the header for one or more blocks being different than the corresponding header(s) in every other node that did not make the exact same modification.

As a result, the solution generated by the modifying node would not solve the cryptographic puzzle presented to any node without the identical modification. Thus, the version of the new block generated by the modifying node is readily recognized as including an improper modification and is rejected by the consensus. This inability to modify past transactions lead to blockchains being generally described as trusted, secure, and/or immutable.

The systems and methods disclosed herein also include performing actions utilizing the distributed consensus achieved through the blockchain. In particular, these actions may be executed by smart contracts. A smart contract is a computer protocol that enables the automatic execution and/or enforcement of an agreement between different parties. The smart contract may include one or more trigger conditions, that, when satisfied, correspond to one or more actions. For some smart contracts, which action(s) from the one or more actions are performed is determined based upon one or more decision conditions. Nodes on the network may subscribe to one or more data streams including data related to a trigger condition and/or a decision condition. Accordingly, the nodes may route the data streams to the smart contract so that the smart contract may detect that a trigger condition has occurred and/or analyze a decision condition to direct the node to perform one or more actions.

Exemplary Database & Distributed Ledger

FIG. 1A depicts an exemplary database system 100 in accordance with one aspect of the present disclosure. FIG. 1A includes a central authority 102, a plurality of nodes 104A, 104B, and 106, a central ledger 108, and a plurality of network connections 110. In one example operation of the database system 100, one of the nodes, for example Node A 104A, would issue a request to the central authority 102 to perform an action on data stored in the central ledger 108. This request may be a request to create, read, update, or delete data that is stored in the central ledger 108.

The central authority 102 would receive the request, processes the request, make any necessary changes to the data stored in the central ledger 108, and inform the requesting node, Node A 104A, of the status of the request. The central authority 102 may also send out status updates to the other nodes on the network about the change made, if any, to the data as requested by Node A 104A. In the database system 100, all interaction with the data stored in the central ledger 108 occurs through the central authority 102. In this way, the central authority functions as a gatekeeper of the data.

Accordingly, the central authority 102 operates a single point of entry for interacting with the data, and consequently the central authority 102 is a single point of failure for the entire database system 100. As such, if the central authority 102 is not accessible to the nodes in the database system 100, then the data stored in the central ledger 108 is not accessible. In another example, each individual node may keep their own databases and then at the end of the day each node sends a copy of their database to the central authority 102 where the databases received are reconciled to form a single cohesive record of the data stored in the central ledger 108.

Conversely, FIG. 1B depicts an exemplary distributed ledger system 112 in accordance with one aspect of the present disclosure. An example of a distributed ledger system 112 is the blockchain system described above. FIG. 1B includes a plurality of nodes 104A, 104B, and 106, a distributed ledger 114, and network connections 110. In a distributed ledger system 112, each node keeps a copy of the distributed ledger 114. As changes are made to the distributed ledger 114 each node updates their copy of the distributed ledger 114. A consensus mechanism may be used by the nodes in the distributed ledger system 112 to decide when it is appropriate to make changes to the distributed ledger 114.

Therefore, each node has their own copy of the distributed ledger 114, which is identical to every other copy of the distributed ledger 114 stored by each other node. The distributed ledger system 112 is more robust than a central authority database system, which is depicted in FIG. 1A, because the distributed ledger system 112 is decentralized and there is no single point of failure.

Exemplary Transaction Flow & Block Propagation

FIG. 2A depicts an exemplary transaction flow 200 in accordance with one aspect of the present disclosure. FIG. 2A includes a transaction 202, three different time frames 204, 206, and 208, a set of nodes, network connections 110, and a distributed ledger 114. The transaction flow 200 may represent a sequential flow of a transaction through a network, such as the network depicted in FIG. 1B. For example, at time 204 Node A 104A generates a transaction 202.

The transaction 202 may use data that is stored in the distributed ledger 114, or the transaction 202 may use data received by the node from outside the distributed ledger 114. Node A 104A may transmit the newly generated transaction to Node C 106 via the network connection 110. At time 206, Node C 106 receives the transaction 202 and confirms that the information contained therein is correct. If the information contained in the transaction 202 is not correct Node C 106 may reject the transaction and not propagate the transaction 202 through the system. If the information contained in the transaction 202 is correct Node C 106 may transmit the transaction 202 to its neighbor Node B 104B.

Similarly, at time 208 Node B 104B may receive the transaction 202 and either confirm or reject the transaction 202. In some embodiments, the Node B 104B may not transmit the confirmed transaction 202, because there are no further nodes to transmit to, or all the nodes in the network have already received transaction 202.

In some embodiments, at any of time frames 204, 206, or 208, any of the nodes may add the confirmed transaction 202 to their copy of the distributed ledger 114, or to a block of transactions stored in the distributed ledger. In some embodiments, confirming the transaction 202 includes checking a cryptographic key-pair for participants involved in the transaction 202. Checking the cryptographic key-pair may follow a set method laid out by a consensus protocol, such as the consensus protocol discussed in FIG. 1B.

FIG. 2B depicts an exemplary block propagation 210 in accordance with one aspect of the present disclosure. FIG. 2B includes two time frames 212 and 214, Node C 106 and Node B 104B, a set of transactions 202A-202D, a set of blocks of transactions 216A-216D, a distributed ledger 114, and a blockchain 218. The block propagation 210 may follow the blockchain system described above, or may follow another blockchain propagation algorithm.

The block propagation 210 may begin with Node C 106 receiving transaction 202A at time 212. When Node C 106C confirms that transaction 202A is valid, the node may add the transaction to a newly generated block 216. As part of adding the transaction 202A to block 216, Node C 106 may solve a cryptographic puzzle and include the solution in the newly generated block 216 as proof of the work done to generate the block 216. This proof of work may be similar to the proof of work described above which utilizes guessing a nonce value. In other embodiments, the transaction 202A may be added to a pool of transactions until enough transactions exist to add together to create a block. Node C 106 may transmit the newly created block 216 to the network at 220. Before or after propagating the block 216, Node C 106 may add the block 216 to its copy of the blockchain 218.

At time 214 Node B 104B may receive the newly created block 216. Node B 104B may verify that the block of transactions 216 is valid by checking the solution to the cryptographic puzzle provided in the block 216. If the solution is accurate then Node B 104B may add the block 216 to its blockchain 218 and transmit the block 216 to the rest of the network at 222.

Exemplary Sequence Diagram

FIG. 3 depicts an exemplary sequence diagram 300 in accordance with one aspect of the present disclosure. FIG. 3 includes a set of nodes 104A, 104B, and 106. At 302, Node A 104A may generate a transaction. The transaction may be transmitted from Node A 104A to Node C 106 at 304. Node C 106 may validate the transaction at 306, and if the transaction is valid, transmit the transaction at 308 to Node B 104B. Node B 104B may validate the transaction at 310. At 312, Node C 106 may compile a block at 312 including the validated transaction. Compiling a block may include generating a solution to a cryptographic puzzle, and linking the block to other blocks, as described in the embodiments above. Once the block is compiled, Node C 106 may transmit the block with the solution at 314 to both Node A 104A and Node B 104B.

Both nodes may then validate the solution to the block at 316. Verifying may include checking a cryptographic key-pair as described above. At 318 the three nodes form a consensus that the solution is valid, and accordingly all the nodes have formed a consensus on the blocks of transactions stored by all the nodes.

Exemplary Node

FIG. 4 depicts an exemplary node 400 in accordance with one aspect of the present disclosure. In some embodiments, node 400 may be the same type of node as Node C 106 in FIGS. 1A-3. In other embodiments, node 400 may be the same type of node as Node A 104A and Node B 104B in FIGS. 1A-3. Node 400 may be capable of performing all the embodiments disclosed herein. In particular, node 400 may utilize the decentralized system described in FIG. 1B, the flows of transactions and blocks described in FIGS. 2A and 2B, and the blockchain system 500 described below in FIG. 5.

FIG. 4 includes at least one processor 402, memory 404, a communication module 406, a set of applications 408, external ports 410, user interface 412, a blockchain manager 414, smart contracts 416, operating system 418, a display screen 420, and input/output components 422. In some embodiments, the node 400 may generate a new block of transactions by using the blockchain manager 414. Similarly, the node 400 may use the blockchain manager 414 in conjunction with the smart contracts 416 stored in memory 404 to execute the functionality disclosed herein.

In other embodiments, the smart contracts 416 operate independent of the blockchain manager 414 or other applications. In some embodiments, node 400 does not have a blockchain manager 414, or smart contracts 416 stored at the node. In some embodiments, the node 400 may have additional or less components than what is described. The components of the node 400 are described in more detail below.

The node 400, as part of a decentralized ledger system 112, or another decentralized or centralized network, may be used to handle systems that interact with and manipulate data and transactions designed for banking identity authentication, banking account funding and distribution, banking card activation, actions triggered by a death registry, using and accessing asset data, lien perfection, obtaining settlement values, contractor ratings, single view of customer's products, and associate licensing.

Exemplary Blockchain System

FIG. 5 depicts an exemplary blockchain system 500 in accordance with one aspect of the present disclosure. FIG. 5 includes a blockchain 502, a block of transactions 504, a Merkle Tree 506, and a transaction 508. The Merkle Tree may be the same Merkle Tree described above that cryptographically links transactions together. In other embodiments, the blockchain system 500 may utilize a different method of organizing transactions in a block. In some embodiments, the blockchain system 500 includes a plurality of blocks connected together to form a chain of blocks of transactions 502.

Each block of transactions 504 may include at least one transaction 508. In other embodiments, each block of transactions 504 has a size limit that necessarily limits the number of transactions that the block may store. Each block of transactions 504 includes a reference to a previous block of transactions that was added to the blockchain 502 prior to the block of transactions 504 being added to the blockchain 502. As such, and as described above, each block of transactions 504 is linked to every other block in the blockchain 502.

In some embodiments, the block of transactions 504 may organize the transactions it has received into a Merkle Tree 506 to facilitate access to the stored transactions. The transactions may be hashed using a cryptographic hash algorithm, such as the algorithms discussed above, and the hash of each transaction is stored in the tree. As the tree is constructed the hash of each adjacent node is hashed together to create a new node that exists at a higher level in the tree. Therefore, the root of the tree, or the node at the top of the tree, is dependent upon the hash of each transaction stored in the tree. Each transaction 508 may include a set of data 510. The set of data 510 may include identifying data for the transaction, and transaction data identifying the nature of the transaction and what the transactions entails.

Exemplary Banking Identity Authentication

FIG. 6 depicts an exemplary flow diagram 600 for a computer-implemented method for manipulating and accessing a blockchain containing identity authentication information for banking services maintained by a network of participants. In some embodiments, the network of participants may be the nodes described above, for example node 400 depicted in FIG. 4. The blockchain used by the participants may be the blockchain 500 depicted in FIG. 5, whose operation is described in FIGS. 2A, 2B, and 5. The steps of the computer-implemented method 600 may be performed by the nodes in the network of participants, such as the nodes described in FIGS. 1A-4. The method 600 may include additional, fewer, or alternative actions, including those described elsewhere herein.

The systems and methods described herein may help an individual and a bank manage the identity authentication process required for opening financial accounts, and conducting financial transactions. For example, when a customer opens an account with a bank the customer's information needs to be validated by the bank. The customer may need to provide proof of who they are to the bank, so that the bank may comply with anti-money laundering regulations, and know your customer regulations. This information may be used to onboard the customer (e.g., open a new account), and/or the information may be used as part of the ongoing relationship the customer has with the bank. Additionally, when the customer interacts with other merchants the customer may need to provide information pertaining to their relationship with their bank to the merchant, which can be cumbersome and slow depending on how the customer information is stored by the bank. If, however, the information about the customer, and the customer's relationship to the bank, was stored on a blockchain network, participants on that network may be able to more easily access the needed information. In some embodiments, the bank may maintain/store information about its customers on a blockchain network. That is, the bank may store customer information on a blockchain network in the form of transactions, and update the customer information as needed via subsequent transactions. Similarly, the customer, or another business, may access the information on the blockchain if they have the necessary access level, e.g., permissions.

The computer-implemented method depicted in the exemplary flow diagram 600 may include (1) receiving at least one bank transaction from at least one participant (block 602), such as via wired communication, or wireless communication or data transmission over one or more radio frequency links or communication channels; (2) verifying the at least one bank transaction (block 604); (3) when the transaction is not valid, generating and communicating (such as via wired communication, or wireless communication or data transmission over one or more radio links or communication channels) a confirmation that the bank transaction is not valid (block 606); or (4) alternatively, when the transaction is valid, adding the bank transaction to a block of transactions (block 608); (5) generating a cryptographic hash for the block of bank transactions (block 610); (6) solving a cryptographic puzzle involving the generated hash (block 612); (7) adding the block to the blockchain (block 614); and/or (8) transmitting the block to at least one other participant (block 616).

In some embodiments, the at least one bank transaction includes identity data for at least one person. The identity data may include personally identifiable information for the at least one person. Examples of identity data may include a person's full name, a person's address information, a person's age, or other identifying information about the person. The bank transactions themselves may include creating/closing accounts for the customer, sending/receiving funds at an account for the customer, changing details about the account for the customer, and combinations thereof.

In some embodiments, verifying further includes checking an access level for the identity data prior to checking the blockchain for the identity data, wherein the access level is set by the at least one person. In other embodiments, verifying further includes checking a public-private key pair for the at least one participant involved in the at least one bank transaction; and when the public-private key pair is invalid, not verifying the at least one bank transaction.

In some embodiments of the computer-implemented method, the block of transactions has metadata, and wherein generating the cryptographic hash further includes generating a hash of the metadata for the block of transactions; and adding the hash for the metadata to the block of bank transactions.

In some embodiments, the cryptographic puzzle has a difficulty assigned to it by a participant in the blockchain network, a group of participants in the blockchain network, an administrator of the blockchain network, or some combination thereof.

Additional Considerations

This detailed description is to be construed as exemplary only and does not describe every possible embodiment, as describing every possible embodiment would be impractical, if not impossible. One may be implement numerous alternate embodiments, using either current technology or technology developed after the filing date of this application.

Further to this point, although the embodiments described herein often utilize credit report information as an example of sensitive information, the embodiments described herein are not limited to such examples. Instead, the embodiments described herein may be implemented in any suitable environment in which it is desirable to identify and control specific type of information. For example, the aforementioned embodiments may be implemented by a financial institution to identify and contain bank account statements, brokerage account statements, tax documents, etc. To provide another example, the aforementioned embodiments may be implemented by a lender to not only identify, re-route, and quarantine credit report information, but to apply similar techniques to prevent the dissemination of loan application documents that are preferably delivered to a client for signature in accordance with a more secure means (e.g., via a secure login to a web server) than via email.

Furthermore, although the present disclosure sets forth a detailed description of numerous different embodiments, it should be understood that the legal scope of the description is defined by the words of the claims set forth at the end of this patent and equivalents. The detailed description is to be construed as exemplary only and does not describe every possible embodiment since describing every possible embodiment would be impractical. Numerous alternative embodiments may be implemented, using either current technology or technology developed after the filing date of this patent, which would still fall within the scope of the claims. Although the following text sets forth a detailed description of numerous different embodiments, it should be understood that the legal scope of the description is defined by the words of the claims set forth at the end of this patent and equivalents. The detailed description is to be construed as exemplary only and does not describe every possible embodiment since describing every possible embodiment would be impractical. Numerous alternative embodiments may be implemented, using either current technology or technology developed after the filing date of this patent, which would still fall within the scope of the claims.

The following additional considerations apply to the foregoing discussion. Throughout this specification, plural instances may implement components, operations, or structures described as a single instance. Although individual operations of one or more methods are illustrated and described as separate operations, one or more of the individual operations may be performed concurrently, and nothing requires that the operations be performed in the order illustrated. Structures and functionality presented as separate components in example configurations may be implemented as a combined structure or component. Similarly, structures and functionality presented as a single component may be implemented as separate components. These and other variations, modifications, additions, and improvements fall within the scope of the subject matter herein.

Additionally, certain embodiments are described herein as including logic or a number of routines, subroutines, applications, or instructions. These may constitute either software (e.g., code embodied on a machine-readable medium or in a transmission signal) or hardware. In hardware, the routines, etc., are tangible units capable of performing certain operations and may be configured or arranged in a certain manner. In exemplary embodiments, one or more computer systems (e.g., a standalone, client or server computer system) or one or more hardware modules of a computer system (e.g., a processor or a group of processors) may be configured by software (e.g., an application or application portion) as a hardware module that operates to perform certain operations as described herein.

In various embodiments, a hardware module may be implemented mechanically or electronically. For example, a hardware module may comprise dedicated circuitry or logic that is permanently configured (e.g., as a special-purpose processor, such as a field programmable gate array (FPGA) or an application-specific integrated circuit (ASIC)) to perform certain operations. A hardware module may also comprise programmable logic or circuitry (e.g., as encompassed within a general-purpose processor or other programmable processor) that is temporarily configured by software to perform certain operations. It will be appreciated that the decision to implement a hardware module mechanically, in dedicated and permanently configured circuitry, or in temporarily configured circuitry (e.g., configured by software) may be driven by cost and time considerations.

Accordingly, the term “hardware module” should be understood to encompass a tangible entity, be that an entity that is physically constructed, permanently configured (e.g., hardwired), or temporarily configured (e.g., programmed) to operate in a certain manner or to perform certain operations described herein. Considering embodiments in which hardware modules are temporarily configured (e.g., programmed), each of the hardware modules need not be configured or instantiated at any one instance in time. For example, where the hardware modules comprise a general-purpose processor configured using software, the general-purpose processor may be configured as respective different hardware modules at different times. Software may accordingly configure a processor, for example, to constitute a particular hardware module at one instance of time and to constitute a different hardware module at a different instance of time.

Hardware modules may provide information to, and receive information from, other hardware modules. Accordingly, the described hardware modules may be regarded as being communicatively coupled. Where multiple of such hardware modules exist contemporaneously, communications may be achieved through signal transmission (e.g., over appropriate circuits and buses) that connect the hardware modules. In embodiments in which multiple hardware modules are configured or instantiated at different times, communications between such hardware modules may be achieved, for example, through the storage and retrieval of information in memory structures to which the multiple hardware modules have access. For example, one hardware module may perform an operation and store the output of that operation in a memory device to which it is communicatively coupled. A further hardware module may then, at a later time, access the memory device to retrieve and process the stored output. Hardware modules may also initiate communications with input or output devices, and may operate on a resource (e.g., a collection of information).

The various operations of example methods described herein may be performed, at least partially, by one or more processors that are temporarily configured (e.g., by software) or permanently configured to perform the relevant operations. Whether temporarily or permanently configured, such processors may constitute processor-implemented modules that operate to perform one or more operations or functions. The modules referred to herein may, in some example embodiments, comprise processor-implemented modules.

Similarly, the methods or routines described herein may be at least partially processor-implemented. For example, at least some of the operations of a method may be performed by one or more processors or processor-implemented hardware modules. The performance of certain of the operations may be distributed among the one or more processors, not only residing within a single machine, but deployed across a number of machines. In some example embodiments, the processor or processors may be located in a single location (e.g., within a home environment, an office environment or as a server farm), while in other embodiments the processors may be distributed across a number of locations.

The performance of certain of the operations may be distributed among the one or more processors, not only residing within a single machine, but deployed across a number of machines. In some example embodiments, the one or more processors or processor-implemented modules may be located in a single geographic location (e.g., within a home environment, an office environment, or a server farm). In other example embodiments, the one or more processors or processor-implemented modules may be distributed across a number of geographic locations.

Unless specifically stated otherwise, discussions herein using words such as “processing,” “computing,” “calculating,” “determining,” “presenting,” “displaying,” or the like may refer to actions or processes of a machine (e.g., a computer) that manipulates or transforms data represented as physical (e.g., electronic, magnetic, or optical) quantities within one or more memories (e.g., volatile memory, non-volatile memory, or a combination thereof), registers, or other machine components that receive, store, transmit, or display information.

As used herein any reference to “one embodiment” or “an embodiment” means that a particular element, feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. The appearances of the phrase “in one embodiment” in various places in the specification are not necessarily all referring to the same embodiment.

Some embodiments may be described using the expression “coupled” and “connected” along with their derivatives. For example, some embodiments may be described using the term “coupled” to indicate that two or more elements are in direct physical or electrical contact. The term “coupled,” however, may also mean that two or more elements are not in direct contact with each other, but yet still co-operate or interact with each other. The embodiments are not limited in this context.

As used herein, the terms “comprises,” “comprising,” “includes,” “including,” “has,” “having” or any other variation thereof, are intended to cover a non-exclusive inclusion. For example, a process, method, article, or apparatus that comprises a list of elements is not necessarily limited to only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Further, unless expressly stated to the contrary, “or” refers to an inclusive or and not to an exclusive or. For example, a condition A or B is satisfied by any one of the following: A is true (or present) and B is false (or not present), A is false (or not present) and B is true (or present), and both A and B are true (or present).

In addition, use of the “a” or “an” are employed to describe elements and components of the embodiments herein. This is done merely for convenience and to give a general sense of the description. This description, and the claims that follow, should be read to include one or at least one and the singular also includes the plural unless it is obvious that it is meant otherwise.

The patent claims at the end of this patent application are not intended to be construed under 35 U.S.C. § 112(f) unless traditional means-plus-function language is expressly recited, such as “means for” or “step for” language being explicitly recited in the claim(s).
