Description Title of Invention INFORMATION PROCESSING DEVICE, INFORMATION PROCESSING 5 METHOD, AND COMPUTER PROGRAM Technical Field [OOOl] The present disclosure relates to an information processing device, an 10 information processing method, and a computer progrann. Background Art [0002] In procedural programming languages such as LISP, Ruby, and Python, 15 variables and function definition infornlation is loaded at program runtime, and the program is executed on the basis of the loaded fi~nction definitions and variable values. Software that interprets and executes such a procedural programming language (a sequential executioll data processing module) loads an application program stated in a procedural programming language every time the software is 20 activated, and thereafter processes input data and outputs a processing result according to the loaded application program. [0003] A characteristic of software that interprets and executes a procedural programlning language is that if a defined variable name is input, the content of that 25 variable may be read out. Likewise, if a function that reads out a defined fi~nction is input, that function code may be output. [0004] In the past, conlputer system architecture involved breaking down the requested specifications into function modules for individual tasks, defining the 30 module control instructions and com~nunicationm eans fiom the start, and using a colnpiler to realize the construction. In function nlodule developlnent, the behavior of a module is defined fro~nth e start using programming code in the function module or by using a predefined code, wvl~iclu~n dergoes a sequence of compiling, linking, and debugging before being incorporated into the system.

Description of Embodiments [0013] 10 Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the appended drawings. Note that, in this specification and the drawings, elements that have st~bstantially the same fullction and structure are denoted with the same reference signs, and repeated explanation is omitted. 15 [0014] Hereinafter, the description will proceed in the following order. 4. Related art and problems thereoD 12. Embodiment of present disclosure> [Functional configuration of information processing system] [Program structure examples] [Use case examnples] <3. Conclusion> [0015] In the case of using a fi~nctiono r variable built into a sequential execution data processing module as a processing request from another communication channel, there exists a method that first closes the channel in advance, and then newly reconfigures the communication channel. However, with this method, if a 15 processing request comes from another communication channel, it becomes necessary to close the open channel and re-open a channel, and the process becomes con~plicated. Moreover, with such a structure, it has not been possible to dynamically realize a request that responds to a processing request from a given comtnunication channel, and while defining fi~nctionsa nd variables or executing a 20 function, changes the value of a variable used by that processing program, or changes some of the filnctions to be used, from another coniniunication chamlel. [0120] Also, with sucll a structure, it has not been possible to realize, without a specialized script program, a configuration enabling modules to construct a network 25 wit11 each other, such as one in which a main sequential execution data processing nlodule answering different requests from multiple similar modules while also sending out a request to another similar module. [0121] Meanwliile, a data processing n~oduleth at receives a script expression via a 30 colinnunicatioli cha~nleol tlier than keyboard input, and returns the processing result via the receiving co~iunnnicationc hannel has also been conceived. However, in the case of multiply connecting such data processing modules via a communication channel, all modules enter a standby state until the last module finishes the process and returns a response, and independent processing was not possible. [O 1221 5 Additionally, sequential execution data processing modules of the related art are respectively defined in specialized script languages. Directly communicating by using anotlier script language and script input communication channel was impossible, requiring internlediary specialized script translation software. Also, a sequential.execution data processing module having a security function was required 10 to re-authenticate a required object every time the channel is switclied, being unable to respond to a new request from another lnodule while maintaining one channel as a secure and encrypted communication session. Because of such restrictions, there were inconveniences, such as the inability to sinlultaneously establish a session for executing payment through another channel while maintaining a session that charges 15 electronic money with an electronic money server or the like, for example. [0123] In contrast, a sequential execution data processing module according to the present embodiment is configured to expand the functionality of a sequential execution data processing module of the related art, and be able to not only load and 20 execute scripts from a keyboard or file via a single channel, but also open multiple network channels, and process successive requests while maintaining the channels. [0124] An information processing device equipped with a sequential execution data processing module according to the present embodiment, by having such a 25 colfiguration, becolnes able to dynamically modify functions that process requests from a given channel and internally held variables, according to a processing request from another channel. By having such a configuration, it becomes possible to process work with different rights via separate channels, such as for the charge and paynie~ito f electronic money, writing and deleting log data, managing energy supply 30 and consunlption quantities in a smart grid metel; car rental time and elapsed time, or service ticket purchase and usage, for example. [Ol 251 Additionally, if a security function is built into a sequential execution data processing module according to the present e~nbodin~euitt, becomes possible to extend a secure session on each chaunel, and successively receive scripts while still 5 maintaining a secure session. For this reason, it becomes possible to securely process payment requests aud charge requests wit11 respect to the same variable holding electronic money from a large number of devices, such as an electronic money server. [0 1261 10 Also, with the input of a script expression via a communication link, the processing request destination is kept waiting uutil a processing result of the input expression is computed and the result is tra~lsmitted via the requesting conlmunication cha~ulel. However, since the message transmitting function of a sequential execution data processing module according to the present enlbodime~lt is 15 switched to the next process after confirming that a message has been sent to the other side, it becomes possible to inunediately switch to the next process. Additionally, it becomes possible to subsequently receive a new message from a peer via another communication channel, and equal message communication that is not in a command-response forruat becomes possible. 20 [O127] Also, a seque~ltial execution data processing module according to the present embodiment has ~nultiple statement analysis fi~nctions and statement recoufiguration fu~ictions that interpret' and recoustruct multiple languages, it is possible to treat the internal expression of fiulction aud variable definitions as one 25 optimal method, in which one channel loads in a given script language A while another channel loads and processes in a different script language B, enabling communication with multiple differing script languages. Also, trarlslation operations, such as transr~littinga script according to an instruction in script language A to another module in script language B, become possible. 30 [0128] Usage of a variable or function defined and set with security in a sequential execution data processing module according to the present embodi~nent always requires an autllentication operation. At this point, since authentication operations fsom multiple channels are managed with an authentication list for each channel, variables and fi~nctions may be used safely, without an autlienticated variable or 5 function being incorrectly used on another channel. [0 1291 Also, even if a processing request is able to use a variable or function of a sequential execution data processing nlodule according to the present embodiment via one communication challuel according to external authentication via an external 10 communication chamlel, since the processing request is linked to the communication channel that issued the request, the variable or function is protected fsom a request via a communication channel with no rights, and may be safely used. [0130] Obviously, exemplary applications of a sequential execution data processing 15 module executed by an information processing device 100 according to an embodiment of the present disclosure are not limited to those indicated above. In addition, ratl~er than just linkage between equipment, similar operation may be realized by installing respective sequential execution data processing modules in separate areas (such as separate directories or separate folders) inside the same 20 equipment. It is also possible to realize a storage nledium storing a sequential execution data processing lnodule executed by an information processing device 100 according to an embodiment of the present disclosure. [0131] The foregoing thus describes preferred embodiments of the present 25 disclosure in detail and with reference to the attached drawings. However, the present disclosure is not li~llitedto such examples.
