Title: Robotic process automation using controller execution model

Description:
CROSS-REFERENCE TO RELATED APPLICATION 
     This application is a continuation of and claims priority from allowed, co-pending U.S. patent application Ser. No. 15/679,013, filed Aug. 16, 2017, and entitled “ROBOTIC PROCESS AUTOMATION USING CONTROLLER EXECUTION MODEL”. 
    
    
     FIELD OF THE INVENTION 
     The present invention embraces a system, a method and a product in the context of robotic process automation (RPA). 
     BACKGROUND 
     Entities are beginning to integrate robotic process automation (RPA) together with cognitive technologies such as speech recognition, natural language processing, and machine learning to automate perpetual and judgement-based tasks. This integration of cognitive technologies and RPA is extending automation to new areas and can help companies become more efficient and agile as they move down the path of becoming fully digital. 
     However, the execution of robotic process automation requires maintaining active connections while preventing unauthorized access to the hosted virtual desktop (HVD) bot. Therefore, there is a need for a system to implement robotic process automation using a controller execution model.

       FIG. 1  presents an exemplary block diagram of the system environment for implementation of a robotic process automation using controller execution model.  FIG. 1  provides a unique system that includes specialized servers and system communicably linked across a distributive network of nodes required to perform the functions of the process flows described herein in accordance with embodiments of the present invention. 
     As illustrated, the system environment  100  includes a network  110 , a system  130 , and a user input system  140 . Also shown in  FIG. 1  is a user of the user input system  140 . The user input system  140  may be a mobile device or other non-mobile computing device. The user may be a person who uses the user input system  140  to execute one or more applications stored thereon. The one or more applications may be configured to communicate with the system  130 , perform a transaction, input information onto a user interface presented on the user input system  140 , or the like. The applications stored on the user input system  140  and the system  130  may incorporate one or more parts of any process flow described herein. 
     As shown in  FIG. 1 , the system  130 , and the user input system  140  are each operatively and selectively connected to the network  110 , which may include one or more separate networks. In addition, the network  110  may include a telecommunication network, local area network (LAN), a wide area network (WAN), and/or a global area network (GAN), such as the Internet. It will also be understood that the network  110  may be secure and/or unsecure and may also include wireless and/or wired and/or optical interconnection technology. 
     In some embodiments, the system  130  and the user input system  140  may be used to implement the processes described herein, including the mobile-side and server-side processes for installing a computer program from a mobile device to a computer, in accordance with an embodiment of the present invention. The system  130  is intended to represent various forms of digital computers, such as laptops, desktops, workstations, personal digital assistants, servers, blade servers, mainframes, and other appropriate computers. The user input system  140  is intended to represent various forms of mobile devices, such as personal digital assistants, cellular telephones, smartphones, and other similar computing devices. The components shown here, their connections and relationships, and their functions, are meant to be exemplary only, and are not meant to limit implementations of the inventions described and/or claimed in this document. 
     In accordance with some embodiments, the system  130  may include a processor  102 , memory  104 , a storage device  106 , a high-speed interface  108  connecting to memory  104 , and a low-speed interface  112  connecting to low speed bus  114  and storage device  106 . Each of the components  102 ,  104 ,  106 ,  108 ,  111 , and  112  are interconnected using various buses, and may be mounted on a common motherboard or in other manners as appropriate. The processor  102  can process instructions for execution within the system  130 , including instructions stored in the memory  104  or on the storage device  106  to display graphical information for a GUI on an external input/output device, such as display  116  coupled to a high-speed interface  108 . In other implementations, multiple processors and/or multiple buses may be used, as appropriate, along with multiple memories and types of memory. Also, multiple systems, same or similar to system  130  may be connected, with each system providing portions of the necessary operations (e.g., as a server bank, a group of blade servers, or a multi-processor system). In some embodiments, the system  130  may be a server managed by the business. The system  130  may be located at the facility associated with the business or remotely from the facility associated with the business. 
     The memory  104  stores information within the system  130 . In one implementation, the memory  104  is a volatile memory unit or units, such as volatile random access memory (RAM) having a cache area for the temporary storage of information. In another implementation, the memory  104  is a non-volatile memory unit or units. The memory  104  may also be another form of computer-readable medium, such as a magnetic or optical disk, which may be embedded and/or may be removable. The non-volatile memory may additionally or alternatively include an EEPROM, flash memory, and/or the like. The memory  104  may store any one or more of pieces of information and data used by the system in which it resides to implement the functions of that system. In this regard, the system may dynamically utilize the volatile memory over the non-volatile memory by storing multiple pieces of information in the volatile memory, thereby reducing the load on the system and increasing the processing speed. 
     The storage device  106  is capable of providing mass storage for the system  130 . In one aspect, the storage device  106  may be or contain a computer-readable medium, such as a floppy disk device, a hard disk device, an optical disk device, or a tape device, a flash memory or other similar solid state memory device, or an array of devices, including devices in a storage area network or other configurations. A computer program product can be tangibly embodied in an information carrier. The computer program product may also contain instructions that, when executed, perform one or more methods, such as those described above. The information carrier may be a non-transitory computer- or machine-readable storage medium, such as the memory  104 , the storage device  104 , or memory on processor  102 . 
     The high-speed interface  1408  manages bandwidth-intensive operations for the system  130 , while the low speed controller  112  manages lower bandwidth-intensive operations. Such allocation of functions is exemplary only. In some embodiments, the high-speed interface  108  is coupled to memory  104 , display  116  (e.g., through a graphics processor or accelerator), and to high-speed expansion ports  111 , which may accept various expansion cards (not shown). In such an implementation, low-speed controller  112  is coupled to storage device  106  and low-speed expansion port  114 . The low-speed expansion port  114 , which may include various communication ports (e.g., USB, Bluetooth, Ethernet, wireless Ethernet), may be coupled to one or more input/output devices, such as a keyboard, a pointing device, a scanner, or a networking device such as a switch or router, e.g., through a network adapter. 
     The system  130  may be implemented in a number of different forms, as shown in  FIG. 1 . For example, it may be implemented as a standard server, or multiple times in a group of such servers. Additionally, the system  130  may also be implemented as part of a rack server system or a personal computer such as a laptop computer. Alternatively, components from system  130  may be combined with one or more other same or similar systems and an entire system  140  may be made up of multiple computing devices communicating with each other. 
       FIG. 1  also illustrates a user input system  140 , in accordance with an embodiment of the invention. The user input system  140  includes a processor  152 , memory  154 , an input/output device such as a display  156 , a communication interface  158 , and a transceiver  160 , among other components. The user input system  140  may also be provided with a storage device, such as a microdrive or other device, to provide additional storage. Each of the components  152 ,  154 ,  158 , and  160 , are interconnected using various buses, and several of the components may be mounted on a common motherboard or in other manners as appropriate. 
     The processor  152  is configured to execute instructions within the user input system  140 , including instructions stored in the memory  154 . The processor may be implemented as a chipset of chips that include separate and multiple analog and digital processors. The processor may be configured to provide, for example, for coordination of the other components of the user input system  140 , such as control of user interfaces, applications run by user input system  140 , and wireless communication by user input system  140 . 
     The processor  152  may be configured to communicate with the user through control interface  164  and display interface  166  coupled to a display  156 . The display  156  may be, for example, a TFT LCD (Thin-Film-Transistor Liquid Crystal Display) or an OLED (Organic Light Emitting Diode) display, or other appropriate display technology. The display interface  156  may comprise appropriate circuitry and configured for driving the display  156  to present graphical and other information to a user. The control interface  164  may receive commands from a user and convert them for submission to the processor  152 . In addition, an external interface  168  may be provided in communication with processor  152 , so as to enable near area communication of user input system  140  with other devices. External interface  168  may provide, for example, for wired communication in some implementations, or for wireless communication in other implementations, and multiple interfaces may also be used. 
     The memory  154  stores information within the user input system  140 . The memory  154  can be implemented as one or more of a computer-readable medium or media, a volatile memory unit or units, or a non-volatile memory unit or units. Expansion memory may also be provided and connected to user input system  140  through an expansion interface (not shown), which may include, for example, dynamic RAM (DRAM) card interface or a Synchronous DRAM (SDRAM) card interface. Such expansion memory may provide extra storage space for user input system  140 , or may also store applications or other information therein. In some embodiments, expansion memory may include instructions to carry out or supplement the processes described above, and may include secure information also. For example, expansion memory may be provided as a security module for user input system  140 , and may be programmed with instructions that permit secure use of user input system  140 . In addition, secure applications may be provided via the RAM, DRAM, or the SDRAM card interfaces, along with additional information, such as placing identifying information on the RAM, DRAM, or the SDRAM card interfaces card in a secure. In some embodiments, the user may use the applications to execute processes described with respect to the process flows described herein. Specifically, the application executes the process flows described herein. It will be understood that the one or more applications stored in the system  130  and/or the user computing system  140  may interact with one another and may be configured to implement any one or more portions of the various user interfaces and/or process flow described herein. 
     The memory  154  may include, for example, flash memory and/or NVRAM memory. In one aspect, a computer program product is tangibly embodied in an information carrier. The computer program product contains instructions that, when executed, perform one or more methods, such as those described herein. The information carrier is a computer- or machine-readable medium, such as the memory  154 , expansion memory, memory on processor  152 , or a propagated signal that may be received, for example, over transceiver  160  or external interface  168 . 
     In some embodiments, the user may use the user input system  140  to transmit and/or receive information or commands to and from the system  130 . In this regard, the system  130  may be configured to establish a communication link with the user input system  140 , whereby the communication link establishes a data channel (wired or wireless) to facilitate the transfer of data between the user input system  140  and the system  130 . In doing so, the system  130  may be configured to access one or more aspects of the user input system  140 , such as, a GPS device, an image capturing component (e.g., camera), a microphone, a speaker, or the like. 
     The user input system  140  may communicate with the system  130  (and one or more other devices) wirelessly through communication interface  158 , which may include digital signal processing circuitry where necessary. Communication interface  158  may provide for communications under various modes or protocols, such as GSM voice calls, SMS, EMS, or MMS messaging, CDMA, TDMA, PDC, WCDMA, CDMA2000, or GPRS, among others. Such communication may occur, for example, through radio-frequency transceiver  160 . In addition, short-range communication may occur, such as using a Bluetooth, Wi-Fi, or other such transceiver (not shown). In addition, GPS (Global Positioning System) receiver module  170  may provide additional navigation—and location-related wireless data to user input system  140 , which may be used as appropriate by applications running thereon, and in some embodiments, one or more applications operating on the system  130 . 
     The user input system  140  may also communicate audibly using audio codec  162 , which may receive spoken information from a user and convert it to usable digital information. Audio codec  162  may likewise generate audible sound for a user, such as through a speaker, e.g., in a handset of user input system  140 . Such sound may include sound from voice telephone calls, may include recorded sound (e.g., voice messages, music files, etc.) and may also include sound generated by one or more applications operating on the user input system  140 , and in some embodiments, one or more applications operating on the system  130 . 
     Various implementations of the systems and techniques described here can be realized in digital electronic circuitry, integrated circuitry, specially designed ASICs (application specific integrated circuits), computer hardware, firmware, software, and/or combinations thereof. These various implementations can include implementation in one or more computer programs that are executable and/or interpretable on a programmable system including at least one programmable processor, which may be special or general purpose, coupled to receive data and instructions from, and to transmit data and instructions to, a storage system, at least one input device, and at least one output device. 
     These computer programs (also known as programs, software, software applications or code) include machine instructions for a programmable processor, and can be implemented in a high-level procedural and/or object-oriented programming language, and/or in assembly/machine language. As used herein, the terms “machine-readable medium” “computer-readable medium” refers to any computer program product, apparatus and/or device (e.g., magnetic discs, optical disks, memory, Programmable Logic Devices (PLDs)) used to provide machine instructions and/or data to a programmable processor, including a machine-readable medium that receives machine instructions as a machine-readable signal. The term “machine-readable signal” refers to any signal used to provide machine instructions and/or data to a programmable processor. 
     To provide for interaction with a user, the systems and techniques described here can be implemented on a computer having a display device (e.g., a CRT (cathode ray tube) monitor, an LCD (liquid crystal display) monitor, an LED (light emitting diode) monitor, or the like) for displaying information to the user and a keyboard and a pointing device (e.g., a mouse or a trackball) by which the user can provide input to the computer. Other kinds of devices can be used to provide for interaction with a user as well; for example, feedback provided to the user can be any form of sensory feedback (e.g., visual feedback, auditory feedback, or tactile feedback); and input from the user can be received in any form, including acoustic, speech, or tactile input. 
     The systems and techniques described here can be implemented in a computing system that includes a back end component (e.g., as a data server), or that includes a middleware component (e.g., an application server), or that includes a front end component (e.g., a client computer having a graphical user interface or a Web browser through which a user can interact with an implementation of the systems and techniques described here), or any combination of such back end, middleware, or front end components. The components of the system can be interconnected by any form or medium of digital data communication (e.g., a communication network). Examples of communication networks include a local area network (“LAN”), a wide area network (“WAN”), and the Internet. 
     The computing system can include clients and servers. A client and server are generally remote from each other and typically interact through a communication network. The relationship of client and server arises by virtue of computer programs running on the respective computers and having a client-server relationship to each other. 
     It will be understood that the embodiment of the system environment illustrated in  FIG. 1  is exemplary and that other embodiments may vary. As another example, in some embodiments, the system  130  includes more, less, or different components. As another example, in some embodiments, some or all of the portions of the system environment  100  may be combined into a single portion. Likewise, in some embodiments, some or all of the portions of the system  130  may be separated into two or more distinct portions. 
     In Robotic Process Automation (RPA), a computer system or robot may mimic the actions of a human being in order to perform a computer-based task. In other words, RPA can be used to interact with application software (or application, for short) through its user interface, as a human being would do. Therefore it is not necessary to integrate RPA with the existing applications at a programming level, thereby eliminating the difficulties inherent to integration, namely bringing together diverse components. In this way, RPA can be used to automate the execution of repetitive and manually intensive activities. RPA&#39;s potential benefits are manifold. They can include reducing costs (by cutting staff), lowering error rates, improving service, reducing turnaround time, increasing the scalability of operations, and improving compliance. 
     In some embodiments, a hosted virtual desktop (HVD) may be a user interface that connects to applications and data that are stored on a cloud provider&#39;s servers rather than on the user&#39;s computer or an entity&#39;s network. Each HVD instance exists as a virtual machine on the service provider&#39;s servers. To the end users, the experience is typically indistinguishable from one in which all their data and applications are local. An HVD provides a significant advantage to the entity in terms of accessibility, cost savings with respect to hardware and their corresponding operating expenses, flexibility and agility for their technology environment, and the ability to support multiple devices concurrently. 
     In some embodiments, each HVD bot is configured to execute one or more processes, via one or more applications requiring one or more authentication credentials. In one aspect, each HVD bot may be configured to access the one or more applications based on a continuum of authentication. In some embodiments, the continuum of authentication includes zero authentication, which includes providing access to an application using no authentication credentials. In some other embodiments, the continuum of authentication includes hard authentication, which includes providing access to an application using full authentication credentials. This means that it requires the strictest combination of credentials. In between the two extremes, “a soft authentication” requires minimal credentials, moderate credentials or most credentials for various points along the continuum. The continuum generally represents the number of credentials required and/or the relative strength of the credentials required for that point on the continuum. 
     In some instances, execution of the one or more processes using hosted virtual desktops (HVDs) require the HVDs to maintain an active connection with each application throughout the execution of the process. HVD bots are typically configured to disable network connectivity and enter a stand-by mode, when they remain idle for too long. However, this setting logs off the HVD bot and in some instances, severs the HVD bot&#39;s connection to one or more processes and/or the local area network, thereby disrupting functionality. To bring the HVD bot back online, the user may have to log into each HVD bot to bring the HVD bot back online. In this regard, each user typically uses a personal access credential to access each HVD bot that is executing robotic processes on applications which require a higher level of access. This poses several challenges. First, if there are tens/hundreds of robotic instances running, managing each bot in the technology environment may become tedious and time consuming. Second, with each user using their own personal access credential to access each HVD bot, the HVD bots may be unprotected from security exposures. 
     The present invention provides the functional benefit of introducing a controller hosted virtual desktop (CHVD) that would span active connections to each HVD bot and keep the connection active at all times. Using this model, each user must access the CHVD, which provides a single point of entry to each HVD bot. In this way, each access can be traced back to a user. For purposes of the invention, the controller execution model, as described, is applied to HVD bots and CHVD hubs. However, a similar model may be applicable to an infrastructure comprising physical desktops, servers, and/or a combination of HVD bots, physical desktops, and servers. 
       FIG. 2  illustrates a process flow for implementing a robotic process automation using a controller execution model  100 , in accordance with an embodiment of the invention. As shown in block  202 , the process flow includes receiving electronically, from a user computing device, a request to establish a communication link with a hosted virtual desktop (HVD) bot. Next, as shown in block  204 , the process flow includes determining a controller hosted virtual desktop (CHVD) hub associated with the HVD bot, wherein the CHVD hub comprises one or more HVD bots connected to the CHVD hub in a hub-and-spoke configuration, wherein the HVD bot is accessible only via the CHVD hub, thereby establishing a hosted virtual desktop (HVD) ring. In this regard, the system may be configured to establish a communication link with one or more HVD bots. In doing so, the system severs a direct communication link between the one or more HVD bots and the user computing system. In one aspect, this implies denying the user computing device direct access to the HVD bot. 
     In response, the system may be configured to couple a CHVD hub to the one or more HVD bots. In this regard, the system may be configured to establish the communication link with the one or more HVD bots. This is achieved by configuring the system to receive one or more authentication credentials associated with the one or more HVD bots. In one aspect, the one or more authentication credentials associated with the one or more HVD bots may be stored in an repository or vault. In response, the authentication credentials may be validated for each of the one or more HVD bots. Once validated, the CHVD hub may be provided access to each of the one or more HVD bots. In response to providing the CHVD hub access to the one or more HVD bots, the system may be configured to reconnect the user computing system to the CHVD hub. In this regard, the system may be configured to establish a communication link between the user computing system and the one or more HVD bots via the CHVD hub. In this way, the CHVD is configured to maintain an active connection with the one or more HVD bots. For example, the authentication credentials for the one or more HVD bots may include, but is not limited to a username, a password, an IP address associated with the HVD bot, biometrics associated with the user authorizing the HVD ring, or the like. 
     Next, as shown in block  206 , the process flow includes receiving one or more authentication credentials associated with the CHVD hub from an encrypted credential repository or vault. In some embodiments, receiving the authentication credentials for the CHVD hub may require user authentication. For example, a user may authenticate his or her identity using a unique alias such as a username and/or password. Further, in some situations, challenge questions, familiar pictures and/or phrases, biometrics, key fob-based alphanumeric codes and/or collocation, authentication of another application such as a similar application or an “overarching” application, and/or the like may be used as types of identity authentication. In this regard, the system may be configured to prompt the user to enter authentication credentials to access the encrypted credential repository or vault. In some embodiments, once the user is authorized to access the encrypted credential repository or vault, the system may be configured to retrieve the authentication credentials for the CHVD hub and automatically provide the user with access to the CHVD hub. In one aspect, the authentication credentials for the CHVD hub may include an IP address associated with the CHVD hub. In some other embodiments, once the user is authorized to access the encrypted credential repository or vault, the system may be configured to provide the user with the authentication credentials to the CHVD hub. In response, the system may be configured to receive the authentication credentials for the CHVD hub from the user, via a manual input, and provide the user with access to the CHVD hub. 
     In some embodiments, the authentication credentials associated with the CHVD hub and the authentication credentials associated with the one or more HVD bots may be stored in the same repository. In this regard, the system may be configured to provide user access to the repository based on authentication credentials associated with the user. In one aspect, the level of authentication required to access the authentication credentials associated with the HVD bot may be the same as the level of authentication required to access the authentication credentials associated with the CHVD hub. In another aspect, the level of authentication required to access the authentication credentials associated with the HVD bot may be different from the level of authentication required to access the authentication credentials associated with the CHVD hub. In some other embodiments, the authentication credentials associated with the CHVD hub and the authentication credentials associated with the one or more HVD bots may be stored in different repositories. 
     Next, as shown in block  208 , the process flow includes validating the one or more authentication credentials associated with the CHVD hub, wherein validating further comprises authorizing the user computing device to access to the CHVD hub. In one aspect, once the authentication credentials for the CHVD hub are retrieved from the encrypted credential repository or vault, the system may be configured to lock or “check-out” the authentication credentials such that no other user may access the CHVD hub at the same time. In some embodiments, once the authentication credentials for the CHVD hub has been used, or checked back in, the system may be configured to update the credentials for the CHVD hub with new authentication credentials such that the same authentication credentials cannot be used to access the CHVD hub more than once. In some other embodiments, the system may be configured to periodically update the authentication credentials required to access the CHVD hub in the encrypted credential repository or vault. In one aspect, the system may be configured to not require addition authentication credentials from the user to access each HVD bot once the CHVD hub has been accessed by the user. In another aspect, in addition to requiring authentication credentials to access the CHVD hub, the system may be configured to require additional authentication from the user to access each HVD bot. 
     In some embodiments, the system may be configured to receive a request from the user computing device to access a second CHVD hub (or one or more HVD bots connected to the second CHVD hub) while being connected to a first CHVD hub. In such instances, the system may be configured to first sever the connection between the user computing system and the first CHVD hub and then establish a communication link with the second CHVD hub. 
     Next, as shown in block  210 , the process flow includes establishing a communication link between the user computing device and the HVD bot, via the CHVD. In some embodiments, the system may be configured to receive electronically, from the user computing device, a request to access a first HVD bot via the CHVD hub. In response, the system may establish a first communication link between the first HVD bot and the user computing device, via the CHVD hub. Once established, the user computing device may be provided access to the one or more applications the first HVD bot is configured to execute. In some embodiments, the system may then receive electronically, from the user computing device, a request to access a second HVD bot via the CHVD hub. In such instances, the system may be configured to sever the first communication link between the user computing device and the first HVD bot before establishing a second communication link between the second HVD bot and the user computing device, via CHVD hub. In another embodiment, the system may be configured to enable the user to access both the first HVD bot and the second HVD bot concurrently. In some embodiments, any attempted access by a user to access the CHVD hub and/or the HVD bot using authentication credentials other than the ones stored in the encrypted credential repository or vault may result in the termination of the active session of the CHVD hub and/or the HVD being accessed. In this way, despite access levels of the user, the present invention provides the functional benefit of enabling access only via authentication credentials stored in the encrypted credential repository or vault. In this way, the system may be configured to provide traceability and track usage. 
       FIG. 3  illustrates an exemplary controller model  300 , in accordance with embodiments of the invention. As shown in  FIG. 3 , the controller model includes user computing device  140 , CHVD_ 1  hub  320  operatively connected to one or more HVD bots (e.g., HVD_ 1 , HVD_ 2  . . . HVD_ 8 ), CHVD_ 2  hub  310  operatively connected to one or more HVD bots (e.g., HVD_ 9 , HVD  10  . . . HVD  16 ), and an encrypted credential repository or vault  330 . Each connection established between the user computing device  140  and a CHVD hub (CHVD_ 1   320  or CHVD_ 2   310 ), are established via a robotic desktop protocol (RDP) connection. Further, each HVD bot connected to a CHVD hub is connected via an active RDP connection.
