     DETAILED DESCRIPTION 
     The methods, systems, and computer program products described herein relate to methods and systems for preventing the incidence of data swaps. Broadly described, a data swap is the problem of visibility of one user data or transaction to other user(s). This potentially occurs in a high user volumetric, concurrent transactions and multi-threaded system environments. Hybrid cloud services continue to grow where cloud services have different security and application domains then legacy security and domain that lead to increasing the possibility of data swap incidents. 
     The methods, systems and computer program products that are described herein add entry and exit points in every component of the concurrent distributed enterprise systems that can auto-manage the correlation between thread identification (ID), and transaction-header identification (IDs), in a hierarchical multi-step cached indexing fashion to prevent data swaps while maintaining the end to end transaction integrity with very low latency cost. The “entry” and “exit points” of the distributed enterprise system can be collectively referred to as “transition points”. The “transaction-header identification” is the transaction identifier (transaction ID), that is assigned when the transaction is started. The transaction header ID is assigned by whichever component is responsible for creating the transaction in response to a start command for the application being executed by the component. The “thread ID” is the identification of an interconnected software exchange of data that comes from integrating systems and data to create a holistic and connected data flow. 
     The disclosure describes a method and framework for data swap prevention that detects data swap before it occurs, provides visibility to components contributing to data swaps and provides end to end transaction integrity. High performance data swap detection is infused and injected into all layers and components of distributed application architecture wherever there is possible data/transaction exchange between components. The framework provided herein ensures data swap identification, notification and prevention in transaction context along with transaction integrity. The framework uses a multi combinatorial mechanism of detecting data swap and assurance of transaction integrity leveraging Globally Unique Identifier GUID, Optionally User Identification (ID), Thread Identification (ID), Transaction Identification (ID), correlation Identification (ID) and other security tokens. In some embodiments, the framework ensures transaction integrity and prevention of data swap through entry/exit bare minimum control in low latency transaction requirements. The methods, systems and computer program products are now described in greater detail with reference to  FIGS.  1 - 7   . 
       FIGS.  1 - 2    are illustrations of an example environment, in which the systems and methods of the present disclosure can prevent inadvertent data swaps.  FIG.  3    is an illustration of a block diagram depicting one embodiment of a system for preventing inadvertent data swaps.  FIG.  4    is a flow/block diagram showing one embodiment a method for data swap prevention that detects data swaps before it occurs, provides visibility to components contributing to data swaps and provides end to end transaction integrity. 
     Aspects of the present invention are described herein with reference to flowchart illustrations and/or block diagrams of methods, apparatus (systems), and computer program products according to embodiments of the invention. It will be understood that each block of the flowchart illustrations and/or block diagrams, and combinations of blocks in the flowchart illustrations and/or block diagrams, can be implemented by computer readable program instructions. 
     These computer readable program instructions may be provided to a processor of a computer, or other programmable data processing apparatus to produce a machine, such that the instructions, which execute via the processor of the computer or other programmable data processing apparatus, create means for implementing the functions/acts specified in the flowchart and/or block diagram block or blocks. These computer readable program instructions may also be stored in a computer readable storage medium that can direct a computer, a programmable data processing apparatus, and/or other devices to function in a particular manner, such that the computer readable storage medium having instructions stored therein comprises an article of manufacture including instructions which implement aspects of the function/act specified in the flowchart and/or block diagram block or blocks. 
     The computer readable program instructions may also be loaded onto a computer, other programmable data processing apparatus, or other device to cause a series of operational steps to be performed on the computer, other programmable apparatus or other device to produce a computer implemented process, such that the instructions which execute on the computer, other programmable apparatus, or other device implement the functions/acts specified in the flowchart and/or block diagram block or blocks. 
     The flowchart and block diagrams in the Figures illustrate the architecture, functionality, and operation of possible implementations of systems, methods, and computer program products according to various embodiments of the present invention. In this regard, each block in the flowchart or block diagrams may represent a module, segment, or portion of instructions, which comprises one or more executable instructions for implementing the specified logical function(s). In some alternative implementations, the functions noted in the blocks may occur out of the order noted in the Figures. For example, two blocks shown in succession may, in fact, be accomplished as one step, executed concurrently, substantially concurrently, in a partially or wholly temporally overlapping manner, or the blocks may sometimes be executed in the reverse order, depending upon the functionality involved. It will also be noted that each block of the block diagrams and/or flowchart illustration, and combinations of blocks in the block diagrams and/or flowchart illustration, can be implemented by special purpose hardware-based systems that perform the specified functions or acts or carry out combinations of special purpose hardware and computer instructions. 
       FIG.  1    is an illustration of a distributed computing application environment, which may include cloud based elements. The distributed computing application environment may include a hybrid application stack and a system of engagement (SOE)  15 , a native cloud stack  16 , a cloud platform as a service (PAAS)  17 , enterprise integration  18  and systems of record (SOR)  19 , which each provide a different type of architecture. The elements for the different types of architectures can include synchronicity/transaction elements, and the numbers of systems of record (SOR) in interfaces involved. The elements for the different types of architectures can also include the heterogeneity of the infrastructure stack involved, and whether the architecture is non-cloud, cloud enabled and/or cloud native. The elements for the architecture can also include whether the architectural component has multiple locations as well as on premise and off premise locations.  FIG.  1    further illustrates an inadvertent data swap. A first user  43  (e.g., user A) and second user  44  (e.g., user B) is depicted that are each interacting in data exchange applications with a distributed computing environment  100 . As illustrated, due to the interaction with the distributed computing environment  100 , the first user  43  retrieves data  45  (user A data) that is correlated correctly to the first user  43 . The second user (user B) inadvertently receives the data  46  for the first user (user A data), which is the result of an inadvertent data swap. The methods, systems and computer program products of the present disclosure detect and reduce data swaps. The volume of transactions through an architectural component is another element that is considered in determining components that are likely to provide for data swap scenarios at the entry and exit points. Security in all the layers is also a factor. 
       FIG.  2    illustrates one embodiment of a hybrid cloud environment having multiple points for data swap potential (which is illustrated by the notation “DS detection”). The hybrid cloud environment may include a front end application, interoperability and operation topology  20 , which may be hereafter referred to as the “front end application  20 ”. The hybrid cloud environment may also include a back end system of reference (SOR)  21 . Front end and back end are terms used by programmers and computer professionals to describe the layers that make up hardware, a computer program or a website which are delineated based on how accessible they are to a user. The back end refers to parts of a computer application or a program&#39;s code that allow it to operate and that cannot be accessed by a user. Most data and operating syntax are stored and accessed in the back end of a system. In some embodiments, the code is comprised of one or more programming languages. The layer above the back end is the front end and it includes all software or hardware that is part of a user interface. Human or digital users interact directly with various aspects of the front end of a program, including user-entered data, buttons, programs, websites and other features. 
     In some embodiments, the front end application layer  20  may include enterprise entry management layer  23 . The enterprise entry management layer  23  may include a fast content delivery network (CDN), edge security, routing procedures, and an application programming interface (API). This layer may be collectively referred to as the API having reference number  23 . The back end SOR  21  may include a data systems landscape  24 , mid range application  25  and complex applications  26 . 
     Still referring to  FIG.  2   , between the front end application layer  20  and the back end SOR  21  may include the front application boundary  27 , and an enterprise integration stack  28 . In one embodiment, the front office application boundary  27  can include web front end functions  28 , WCM/ECM functions  29 , and mobile functions  30 . The front office application boundary  27  can also include a hybrid application stack and data stack  31 , as well as a heterogenous platform and operations player  32 , and cloud native applications  33 . 
     Still referring to  FIG.  2   , every component where transaction and security context changes can be a potential hotspot for data swap. Asynchronous interfaces and multi-threaded services provide additional hotspots for accidental mix of request and response. The hotspots are designated “DS detection” having reference number  47 . The notation “DS detection” notes high performance data swap (DS) detection controls being injected across the hybrid cloud landscape depicted in  FIG.  2   . In this example, the entry/exit is the minimum control to prevent data swap when microseconds latency is not acceptable. 
       FIG.  3    illustrates one embodiment of a data swap detection system framework  200  for providing data swap prevention. The framework depicted in  FIG.  3    can inject co-relational identification (ID) and the global unique identifier (GUID) at the entry point, e.g., data swap microservice interface  35 . The data swap microservice interface  35  can provide for connection of the microservice at each data swap detection point  47  as depicted, in which the data swap detection points  47  can provide transition points (exit and/or exit points) to the distributed computing environment. For example, the entry point can be from the API gateway  23  of the front end application  20 . From the API gateway  23  to the data swap detection microservice  200 , the data swap detection microservice  200  provides data swap (DS) detection by creating mapping between the thread dentification (ID) to the global unique identifier (GUID) and the correlation ID. The tread ID to GUID mapping engine  36  depicted in  FIG.  3    can provide the aforementioned mapping. The framework for data swap prevention and detection depicted in  FIG.  3    may be present at any data or transaction exchange interface, illustrated by the annotation DS detection in  FIG.  2   . Particularly, the data or transaction exchange interfaces having high volume are the likely points of data swaps, and hence would provide a suitable location for the framework for data swap prevention depicted in  FIG.  3   . In some embodiments, the framework that provides the data swap detection microservice  200  includes a transaction counter  37 . The transaction counter  37  can track the number of transactions through a transition point, e.g., entry point or exit point, to determine when a high volume transition point is present. For example, a threshold number of transactions may be preset. When the number of transactions exceed the preset threshold for a given amount of time, that transition point where those transactions occur can be considered a point at which data swaps can occur, which is the point at which data swap detection  47  can occur. The exit policy is to match the thread identification (ID) to the global unique identifier (GUI) and the correlation identification (ID). The validator  38  can include a signal generator. The signal generator sends instructions regarding potential data swaps. 
     Data swap detection can be provided by data swap detection microservices  200 . In one example, the microservices can be performed at the API gateway  23  for the front end application  20 . This is an example as the entry of data, or requests for data, and its processing to avoid data swaps. In some embodiments, the microservices validate correlation ID and global unique identifier (GUID) are present at the API. This is one of the initial steps of detecting for a data swap. If the correlation ID and global unique identifier (GUID) are not present, than the data swap detection microservice  200  issues a flag, i.e., the microservices can throw an error code. This can be performed by the transaction validator  38 . 
     The data swap detection microservice  200  can also validate tokens belonging to the global unique identifier (GUID). The tokens of the GUID can be validated using the JSON web token (JWT) payload. JSON Web Tokens are an open, industry standard RFC  7519  method for representing claims securely between two parties. JSON Web Token (JWT) defines a compact and self-contained way for securely transmitting information between parties as a JSON object. This information can be verified and trusted because it is digitally signed. JWTs can be signed using a secret (with the HMAC algorithm) or a public/private key pair using RSA or ECDSA. The microservice uses the correlation identification (ID) for logging/event creation. 
     For the data swap detection microservice  200  to be successful some assumptions are made. For example, authorization and access controls for resources being accessed are in place. In some examples, the users have a token for access to all of the resources, e.g., all of the databases from which data could be the source of a data swap. In other examples, in which user tokens are not in place to access databases, an application level user ID may be employed that ensures the data being accessed is in context with the global user identification (GUID). 
     The data swap detection microservice  200  can then track for data swaps to third party API/systems API  39 . The microservice again validates correlation identification (ID) and global user identification (GUID) that goes out to the third party API/systems API  39 , and that the correlation (ID) and GUID that goes out, comes back in. Further, the microservice ensures that the App-Transaction Id is present in incoming request and is logged. Validation can be provided by the transaction validator  38 . 
     The framework for the data swap detection microservices  200  may also employ an event engine  40 , such as KAFKA topics. Kafka is a publish-subscribe based messaging system exchanging data between processes, applications, and servers. Kafka is a software where topics can be defined (think of a topic as a category), applications can add, process and reprocess records. Applications connect to this system and transfer a record onto the topic. A record can include any kind of information; for example, information about an event that has happened on a website, or an event that is supposed to trigger an event. Another application may connect to the system and process or re-process records from a topic. The data sent is stored until a specified retention period has passed by. 
     From the data swap detection microservice  200  to the event engine  40 , e.g., Kafka topic event engine, a determination is made to confirm co-relation identification (ID), and global unique identifier (GUID) included in the event, e.g., an event in which a data swap can occur. From the event engine  40 , e.g., Kafka topic event engine, to the microservice, the microservice can validate correlation Id and that the global unique identifier (GUID) are present, or else the microservice with throw an error indication. This validation step may be performed by the transaction validator  38 . As long as, the correlation ID and global unique identifier (GUID) are present and used as described below, their correct value will be validated by API gateway, or by an orchestrator for long running transactions, or any request originator. 
     The data swap microservice can validate that the token belongs to global unique identifier (GUID). The microservices uses the correlation identification (ID) for logging/event creation. 
     For the data swap prevention microservice  200  to be successful some assumptions are made. For example, authorization and access controls for resources being accessed are in place. In some examples, the users have a token for access to all of the resources, e.g., all of the databases from which data could be the source of a data swap. In other examples, in which user tokens are not in place to access databases, an application level user ID may be employed that ensures the data being accessed is in context with the global user identification (GUID). 
     Still referring to  FIG.  3   , from the event engine  40 , e.g., Kafka topic, to the integration service/enterprise service bus (ESB)(System of record (SoR) wrapper web service), the enterprise service bus can ensure that the correlation identification (ID) and global user identification (GUID) that goes into the webservice for the system of record (SOR) matches what comes back. This includes the system of records (SOR) local transaction ID as App-transaction ID and logs the same. This can enable end to end traceability. 
     Still referring to  FIG.  3   , the microservices for data swap detection  200  and prevention framework includes a web service that can be integrated into the framework depicted in  FIG.  2    through an integration/service bus  102 . The integration service bus  1023  can provide connectivity to the data swap detection sites  47  that are depicted in  FIG.  2   . The web service ensures the correlation identification ID and the global unique identifier are included. 
     Turning to the integration server to Kafka topic, the web service ensures the correlation identification (ID) and the global unique identifier (GUID) are included. In some examples, in a legacy application, the system of record (SoR) would not directly be engaged with the events related to potential data swaps, and the back end system of record (SOR) may have a wapper webservices/API. 
     Turning to the system of record (SoR), no change is expected for the integration of the data swap architecture. In most cases the SOR already has a local transaction identification (ID), which is sent back to the webservice. Referring to  FIG.  3   , each time the data swap detection system  100  detects a data swap, e.g., the thread ID and the transaction header ID do not match, the system can send comments to interrupt data transfer to avoid the incidence of a data swap. This step can be provided by the data transmission interrupt  48 . 
       FIG.  4    is a flow/block diagram showing one embodiment a method for reducing data swaps. At block  1 , at the first entry point  5  of a request, a global transaction identification (ID) is generated and embedded in the request header. The first entry point for the request can be the application programming interface (API). 
     At block  2 , the method may continue with the request from the application programming interface (API) gateway being published asynchronously to transaction integrity model, as it continues to back end to front end adaptors. In some embodiments, the requires meta data must contain the global transaction identification (ID) ,which is introduced by the API gateway. 
     At block  3 , within the framework of the transaction integrity model, the method further includes determining the request identification (ID), global transaction identification (ID), user identification (ID) for the request being received in the transaction integrity model. 
     Referring to block  4 , within the framework of the transaction integrity model, for every new service invoked, a key value pair cached match is performed mapping the thread identification (thread ID) to the global transaction identification (ID). 
     At block  5 , within the framework of the transaction integrity model, for every new service request, from a specific thread (as identified by thread ID), a match is made to the identifications for the request that include the request identification (ID), global transaction identification (ID), user identification (ID). In some examples, the request identification (ID), the global transaction identification (ID), and the user identification (ID) are referred to as the request trio parameters. 
     Referring to block  6 , within the framework of the transaction, a check is performed of the thread ID for the thread at which the request was picked up, and the thread ID for the thread of the component that generated the response. 
     At block  7 , within the framework of the transaction integrity model and before the request reaches the gateway, a transaction integrity flag is generated, e.g., a flag of yes or no, based upon which gateway decides whether the transaction details are to be delivered to the consumer. A flag for transaction integrity, e.g., a flag of yes for data integrity, illustrates that there is no data swap. A flag of “yes” for the transaction integrity flag can be issued when the request trio parameters match the thread ID. A flag for no transaction integrity, e.g., a flag of no for data integrity, illustrates that there is a data swap or potential for a data swap. A flag of “no” for the transaction integrity flag can be issued when the request trio parameters do not match the thread ID. 
     The method may further include block  8 , which is transmitting the data as part of a transaction using a distributed computing environment, when the transaction integrity flag indicates that the request trio parameters match the thread ID, which indicates that there is no data swap. 
     The execution model for this framework can include classify transactions into various service quality of service levels in a hierarchical tree structure. For example, transactions taking on the order of milliseconds can be considered very high, while transactions taking 0.5 to 1 second would be considered high, and 1 to 3 seconds would be considered medium, etc. 
     The execution model for the framework depicted in  FIG.  4    can also capture and request response detailed asynchronously on an event engine, such as a Quality of Service (QoS) Kafka topic. Quality of Service (QoS) is a set of technologies that work on a network to guarantee its ability to dependably run high-priority applications and traffic under limited network capacity . . . . Measurements of concern QoS are bandwidth (throughput), latency (delay), jitter (variance in latency), and error rate. 
     Kafka is a publish-subscribe based messaging system exchanging data between processes, applications, and servers. Kafka is a software where topics can be defined (think of a topic as a category), applications can add, process and reprocess records. Applications connect to this system and transfer a record onto the topic. A record can include any kind of information; for example, information about an event that has happened on a website, or an event that is supposed to trigger an event. Another application may connect to the system and process or re-process records from a topic. The data sent is stored until a specified retention period has passed by. 
     Based on QoS Kafka topics are kept separate for each category of transactions, which decides priority of processing. 
     It keeps transaction profile templates ready based on static code analysis of each transaction that goes live so it has clear visibility of all services/systems this transaction can reach. It also knows which systems are mandatory to respond for the transaction to complete. 
       FIG.  5    illustrates a processing system  400  used by or comprised by the system  200  of  FIG.  3    for reducing the incidence of inadvertent data swaps, in accordance with the methods and systems described above in  FIGS.  1 - 4   .

A network adapter card or network interface in each computing/processing apparatus receives computer readable program instructions from the network and forwards the computer readable program instructions for storage in a computer readable storage medium within the respective computing/processing device. 
     Computer readable program instructions for carrying out operations of the present invention may be assembler instructions, instruction-set-architecture (ISA) instructions, machine instructions, machine dependent instructions, microcode, firmware instructions, state-setting data, or either source code or object code written in any combination of one or more programming languages, including an object oriented programming language such as Smalltalk, C++, spark, R language, or the like, and conventional procedural programming languages, such as the “C” programming language or similar programming languages. The computer readable program instructions may execute entirely on the user&#39;s computer, partly on the user&#39;s computer, as a stand-alone software package, partly on the user&#39;s computer and partly on a remote computer or entirely on the remote computer or server. In the latter scenario, the remote computer may be connected to the user&#39;s computer through any type of network, including a local area network (LAN) or a wide area network (WAN), or the connection may be made to an external computer (for example, through the Internet using an Internet Service Provider). In some embodiments, electronic circuitry including, for example, programmable logic circuitry, field-programmable gate arrays (FPGA), or programmable logic arrays (PLA) may execute the computer readable program instructions by utilizing state information of the computer readable program instructions to personalize the electronic circuitry, in order to perform aspects of the present invention. 
     In one embodiment, the present disclosure provides a non-transistory computer readable storage medium that includes a computer readable program for preventing inadvertent data swaps. The non-transitory computer readable program when executed on a computer causes the computer to perform the steps of measuring the volume of transactions in distributed computing environment to determine locations for potential data swaps; and managing the correlation between a thread identification (ID) and transaction header (ID) for transactions in the distributed computing environment. The computer program product can perform, using a processor, a data transmission interruption to avoid data swaps at the locations for potential data swaps, when the thread identification (ID) and transaction header (ID) do not match. 
     It is to be understood that although this disclosure includes a detailed description on cloud computing, implementation of the teachings recited herein are not limited to a cloud computing environment. Rather, embodiments of the present invention are capable of being implemented in conjunction with any other type of computing environment (e.g., Internet of thing (IOT)) now known or later developed. Cloud computing is a model of service delivery for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, network bandwidth, servers, processing, memory, storage, applications, virtual machines, and services) that can be rapidly provisioned and released with minimal management effort or interaction with a provider of the service. This cloud model may include at least five characteristics, at least three service models, and at least four deployment models. Characteristics are as follows: 
     On-demand self-service: a cloud consumer can unilaterally provision computing 
     capabilities, such as server time and network storage, as needed automatically without requiring human interaction with the service&#39;s provider. 
     Broad network access: capabilities are available over a network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, laptops, and PDAs). 
     Resource pooling: the provider&#39;s computing resources are pooled to serve multiple consumers using a multi-tenant model, with different physical and virtual resources dynamically assigned and reassigned according to demand. There is a sense of location independence in that the consumer generally has no control or knowledge over the exact location of the provided resources but may be able to specify location at a higher level of abstraction (e.g., country, state, or datacenter). 
     Rapid elasticity: capabilities can be rapidly and elastically provisioned, in some cases automatically, to quickly scale out and rapidly released to quickly scale in. To the consumer, the capabilities available for provisioning often appear to be unlimited and can be purchased in any quantity at any time. 
     Measured service: cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user accounts). Resource usage can be monitored, controlled, and reported, providing transparency for both the provider and consumer of the utilized service. 
     Service Models are as follows: 
     Software as a Service (SaaS): the capability provided to the consumer is to use the provider&#39;s applications running on a cloud infrastructure. The applications are accessible from various client devices through a thin client interface such as a web browser (e.g., web-based email). The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, storage, or even individual application capabilities, with the possible exception of limited user-specific application configuration settings. Platform as a Service (PaaS): the capability provided to the consumer is to deploy onto the cloud infrastructure consumer-created or acquired applications created using programming languages and tools supported by the provider. The consumer does not manage or control the underlying cloud infrastructure including networks, servers, operating systems, or storage, but has control over the deployed applications and possibly application hosting environment configurations. 
     Infrastructure as a Service (IaaS): the capability provided to the consumer is to provision processing, storage, networks, and other fundamental computing resources where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications. The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, deployed applications, and possibly limited control of select networking components (e.g., host firewalls). 
     Deployment Models are as follows: 
     Private cloud: the cloud infrastructure is operated solely for an organization. It may be managed by the organization or a third party and may exist on-premises or off-premises. Community cloud: the cloud infrastructure is shared by several organizations and supports a specific community that has shared concerns (e.g., mission, security requirements, policy, and compliance considerations). It may be managed by the organizations or a third party and may exist on-premises or off-premises. 
     Public cloud: the cloud infrastructure is made available to the general public or a large industry group and is owned by an organization selling cloud services. 
     Hybrid cloud: the cloud infrastructure is a composition of two or more clouds (private, community, or public) that remain unique entities but are bound together by standardized or proprietary technology that enables data and application portability (e.g., cloud bursting for load balancing between clouds). 
     A cloud computing environment is service oriented with a focus on statelessness, low coupling, modularity, and semantic interoperability. At the heart of cloud computing is an infrastructure that includes a network of interconnected nodes. 
     Referring now to  FIG.  6   , illustrative cloud computing environment is depicted. As shown, cloud computing environment includes one or more cloud computing nodes  10  with which local computing devices used by cloud consumers, such as, for example, personal digital assistant (PDA) or cellular telephone  54 A, desktop computer  54 B, laptop computer  54 C, and/or automobile computer system  54 N may communicate. Nodes  10  may communicate with one another. They may be grouped (not shown) physically or virtually, in one or more networks, such as Private, Community, Public, or Hybrid clouds as described hereinabove, or a combination thereof. This allows cloud computing environment to offer infrastructure, platforms and/or software as services for which a cloud consumer does not need to maintain resources on a local computing device. It is understood that the types of computing devices  54 A,  54 B,  54 C and  54 N shown in  FIG.  8    are intended to be illustrative only and that computing nodes  10  and cloud computing environment  50  can communicate with any type of computerized device over any type of network and/or network addressable connection (e.g., using a web browser). 
     Referring now to  FIG.  7   , a set of functional abstraction layers provided by cloud 
     computing environment (see  FIG.  6   ) is shown.
