Summary of the Invention

Problems to be Solved by the Invention

[0005] In order to suppress the spread of infectious diseases, it is considered useful to appropriately clean the objects that a person has approached and the objects that a person has contacted. However, Japanese Patent Publication No. 2015-533248, International Publication No. 2013 / 031481, and Japanese Unexamined Patent Application Publication No. 2017-004165 do not consider cleaning the objects that a person has approached and the objects that a person has contacted.

[0006] The present disclosure has been made in view of the above circumstances, and an object thereof is to provide an information processing apparatus, an information processing method, and an information processing program capable of suppressing the spread of infectious diseases through objects.

Means for Solving the Problems

[0007] The information processing apparatus of the present disclosure is an information processing apparatus including at least one processor. The processor identifies at least one of an object touched by a person and an object approached by a person within a certain distance for a certain period or more, and performs control to store in a storage device log data for use in notifying a cleaning request for the object, the log data including identification information of the identified object.

[0008] Note that in the information processing apparatus of the present disclosure, the processor may notify a cleaning request for an object whose identification information is included in the log data.

[0009] Further, in the information processing apparatus of the present disclosure, for an area predetermined as a contamination management area in a hospital, the processor may notify a cleaning request at a timing predetermined as a timing when the object can be cleaned.

[0010] Further, in the information processing apparatus of the present disclosure, for an area other than the area predetermined as a contamination management area in a hospital, the processor performs at least one of contact with an object whose identification information is included in the log data and approach within a certain distance for a certain period or more, and at least one of a first timing when it is determined that a person located in that area has a positive infectious disease test result and a second timing when it is determined that the person satisfies conditions suspected of being infected with an infectious disease, the processor may notify a cleaning request.

[0011] Further, in the information processing apparatus of the present disclosure, the processor may notify a cleaning request for an object touched by at least one of a person whose infectious disease test result is determined to be positive and a person who is determined to satisfy conditions suspected of being infected with an infectious disease and an object approached within a certain distance for a certain period or more from at least one of the first timing and the second timing until a second certain period before.

[0012] Further, in the information processing apparatus of the present disclosure, the second certain period may be determined according to the maximum residual period of an infectious disease pathogen for each material of the object.

[0013] In addition, in the information processing apparatus of the present disclosure, when the processor determines that at least one of a person whose test result for an infectious disease is found to be positive and a person who is found to satisfy the conditions suspected of being infected with an infectious disease is at least one of the timings of the first timing and the second timing, after the timing when the person has contacted an object containing identification information in the log data or has approached within a certain distance of the object for a certain period of time or more, the information processing apparatus may further notify the object that has not been cleaned of information representing a person who has contacted the object within a second certain period from that timing.

[0014] In addition, in the information processing apparatus of the present disclosure, the processor may further notify a cleaning request for an object that is the target of the cleaning request and has contacted an object that has not been cleaned.

[0015] In addition, in the information processing apparatus of the present disclosure, the processor may notify a cleaning request while varying the message at the first timing and the second timing.

[0016] In addition, in the information processing apparatus of the present disclosure, when a display device is provided on a specified object, the processor may notify a cleaning request to be displayed on the display device.

[0017] In addition, in the information processing apparatus of the present disclosure, the processor may delete a log that has passed the incubation period of the pathogen of an infectious disease from the time of acquisition of the log among the logs included in the log data.

[0018] In addition, in the information processing apparatus of the present disclosure, when identifying an object, the processor may make a certain period variable according to the protective state of a person.

[0019] In addition, the information processing method of the present disclosure is a process in which a processor of an information processing apparatus executes control for storing, in a storage device, log data for identifying at least one of an object contacted by a person and an object that the person has approached within a certain distance for a certain period of time or more, the log data including identification information of the identified object, for use in notifying a cleaning request for the object.

[0020] In addition, the information processing program of the present disclosure is log data for identifying at least one of an object touched by a person and an object that a person has approached within a certain distance for a certain period of time or more, and is used to notify a cleaning request for the object. It is for causing a processor included in an information processing device to execute a process of controlling to store log data including identification information of the identified object in a storage device.

[0021] In addition, the storage device of the present disclosure is a storage device incorporated in an information processing device, and stores log data including identification information of an object identified as at least one of an object touched by a person and an object that a person has approached within a certain distance for a certain period of time or more, in order to notify a cleaning request for the object by the information processing device.

Embodiments for Carrying Out the Invention

[0024] Hereinafter, with reference to the drawings, exemplary embodiments for implementing the technology of the present disclosure will be described in detail.

[0025] First, with reference to FIG. 1, the configuration of the information processing system 10 according to the present embodiment will be described. As shown in FIG. 1, the information processing system 10 includes an information processing apparatus 12 and a plurality of log acquisition apparatuses 14. The information processing apparatus 12 and each log acquisition apparatus 14 are each connected to a network and are capable of communicating with each other. In the present embodiment, an example in which the information processing apparatus 12 and each log acquisition apparatus 14 are installed in a hospital will be described.

[0026] The log acquisition apparatus 14 acquires logs that detect that a person has touched an object, that the person has left the object after touching the object, that the person has approached within a certain distance of the object, and that the person has moved away by more than a certain distance after approaching within a certain distance of the object. The person here is, for example, a patient who has visited the hospital, a family member of the patient, and a medical staff member working in the hospital. Also, the object here is, for example, an imaging apparatus that captures a medical image, a control apparatus that controls the imaging apparatus, and an operation terminal provided with a touch panel operated by a person, such as an electrical device. Note that the object is not limited to an electrical device and may be an object other than an electrical device. Hereinafter, the fact that a person has approached within a certain distance of an object will be simply referred to as "approach". Also, the certain distance in this case (for example, 10 cm) may be determined in advance according to, for example, the apparatus used for detecting the approach, or may be determined in advance according to the hospital policy.

[0027] Examples of the log acquisition device 14 include a device that detects the approach of a person and an object by short-range wireless communication such as an IC (Integrated Circuit) tag. In this case, a person is identified by the individual identification information of the IC tag carried by the person, and an object is identified by the individual identification information of the IC tag reader provided on the object. Further, examples of the log acquisition device 14 include a device that detects the contact between a person and an object by using the electromagnetic noise emitted by a smart watch worn on the person's wrist. Further, examples of the log acquisition device 14 include a device that detects the contact and approach between a person and an object by performing image analysis processing on a moving image captured by a camera at a predetermined frame rate. The log acquisition device 14 is not limited to the above examples as long as it can detect that a person has contacted an object, has left after contacting the object, has approached the object, and has left after approaching the object, and may be a device that performs the above detection by other principles.

[0028] The log acquisition device 14 transmits the acquired log to the information processing device 12. An example of the log is shown in FIG. 2. As shown in FIG. 2, the log acquired by the log acquisition device 14 includes the identification information of the person who has contacted or approached the object, the identification information of the object, the position information indicating the position in the hospital where the object is installed, and the category indicating the contact or approach. Further, as shown in FIG. 2, the log acquired by the log acquisition device 14 further includes the start date and time which is the date and time when the person starts to contact or approach the object, and the end date and time of the contact or approach which is the date and time when the person leaves the object after contacting or approaching the object.

[0029] Next, referring to FIG. 3, the hardware configuration of the information processing apparatus 12 according to the present embodiment will be described. As shown in FIG. 3, the information processing apparatus 12 includes a CPU (Central Processing Unit) 20, a memory 21 as a temporary storage area, and a non-volatile storage unit 22. Further, the information processing apparatus 12 includes a display 23 such as a liquid crystal display, an input device 24 such as a keyboard and a mouse, and a network I / F (InterFace) 25 connected to a network. The CPU 20, the memory 21, the storage unit 22, the display 23, the input device 24, and the network I / F 25 are connected to a bus 27.

[0030] The storage unit 22 is realized by an HDD (Hard Disk Drive), an SSD (Solid State Drive), a flash memory, or the like. An information processing program 30 is stored in the storage unit 22 as a storage medium. The CPU 20 reads the information processing program 30 from the storage unit 22 and expands it in the memory 21, and executes the expanded information processing program 30.

[0031] Also, first log data 32 and second log data 34 are stored in the storage unit 22. The first log data 32 and the second log data 34 are log data for use in notifying a cleaning request for an object. Specifically, the first log data 32 includes logs regarding the approach and contact of people in a first area predetermined as a contamination management area in the hospital, and the second log data includes logs regarding the approach and contact of people in a second area other than the first area in the hospital. Details of the first log data 32 and the second log data 34 will be described later. For the classification of the first area and the second area in the hospital, for example, the concept of zoning in the hospital can be applied.

[0032] Next, with reference to FIG. 4, the functional configuration of the information processing apparatus 12 according to the present embodiment will be described. As shown in FIG. 4, the information processing apparatus 12 includes an acquisition unit 40, a determination unit 42, a storage control unit 44, an extraction unit 46, a notification unit 48, and a deletion unit 50. When the CPU 20 executes the information processing program 30, it functions as the acquisition unit 40, the determination unit 42, the storage control unit 44, the extraction unit 46, the notification unit 48, and the deletion unit 50.

[0033] The acquisition unit 40 acquires the log transmitted from the log acquisition device 14 via the network I / F 25.

[0034] The determination unit 42 uses the position information included in the log acquired by the acquisition unit 40 to determine whether the installation position of the object indicated by the identification information of the object included in the log is within the first region or within the second region. Further, the determination unit 42 determines whether the period from the "start date and time" to the "end date and time" of the log whose category is "approach" among the logs acquired by the acquisition unit 40 is equal to or longer than a first fixed period (for example, 15 minutes). The first fixed period in this case may be determined in advance according to, for example, the definition of close contact, or may be determined in advance according to the policy of the hospital.

[0035] The storage control unit 44 controls to store, in the first log data 32 of the storage unit 22, the log acquired by the acquisition unit 40 whose category is "contact" and for which the determination unit 42 has determined that the installation position of the object is within the first region. Further, the storage control unit 44 controls to store, in the second log data 34 of the storage unit 22, the log acquired by the acquisition unit 40 whose category is "contact" and for which the determination unit 42 has determined that the installation position of the object is within the second region. That is, in the first log data 32, logs including the identification information of the object identified as having been contacted by a person in the first region are accumulated. Also, in the second log data 34, logs including the identification information of the object identified as having been contacted by a person in the second region are accumulated.

[0036] Further, the memory control unit 44 controls to store, in the first log data 32 of the storage unit 22, the log acquired by the acquisition unit 40, where the category is "approach", the determination unit 42 determines that the installation position of the object is within the first region, and the determination unit 42 determines that the period from the "start date and time" to the "end date and time" is equal to or longer than the first fixed period. Also, the memory control unit 44 controls to store, in the second log data 34 of the storage unit 22, the log acquired by the acquisition unit 40, where the category is "approach", the determination unit 42 determines that the installation position of the object is within the second region, and the determination unit 42 determines that the period from the "start date and time" to the "end date and time" is equal to or longer than the first fixed period. That is, the first log data 32 accumulates logs including the identification information of the object identified as being approached by a person within a certain distance for a period equal to or longer than the first fixed period in the first region. Also, the second log data 34 accumulates logs including the identification information of the object identified as being approached by a person within a certain distance for a period equal to or longer than the first fixed period in the second region. Among the logs acquired by the acquisition unit 40, the logs where the category is "approach" and the determination unit 42 determines that the period from the "start date and time" to the "end date and time" is less than the first fixed period are discarded. Alternatively, without discarding these logs, they may be included in the first log data 32 or the second log data 34 according to the installation position of the object. In this case, in the first log data 32 and the second log data 34, it is only necessary to set a notification flag for the logs where the category is "approach" and the determination unit 42 determines that the period from the "start date and time" to the "end date and time" is equal to or longer than the first fixed period.

[0037] When it is determined at the first timing that a person whose identification information is included in the second log data 34 has a positive infectious disease test result, the extraction unit 46 extracts, from the second log data 34, the identification information of the object that the person with the positive infectious disease test result has contacted. The person whose identification information is included in the second log data 34 means a person who has performed at least one of contacting and approaching within a certain distance of the object whose identification information is included in the second log data 34 and is located within the second region.

[0038] Further, at the first timing, the extraction unit 46 also extracts the identification information of the object that a person who has been found to have a positive test result for an infectious disease has approached from the second log data 34. This first timing is, for example, the timing when the identification information of a person with a positive test result for an infectious disease is input to the information processing device 12.

[0039] Further, at the second timing when it is determined that a person whose identification information is included in the second log data 34 satisfies the condition of being suspected of being infected with an infectious disease, the extraction unit 46 extracts from the second log data 34 the identification information of the object that the person who has been found to satisfy the condition of being suspected of being infected with an infectious disease has contacted. The condition of being suspected of being infected with an infectious disease is, for example, a predetermined condition such as a body temperature of 37.5 degrees or higher or coughing.

[0040] Further, at the second timing, the extraction unit 46 also extracts the identification information of the object that a person who has been found to satisfy the condition of being suspected of being infected with an infectious disease has approached from the second log data 34. This second timing is, for example, the timing when the identification information of a person who has been found to satisfy the condition of being suspected of being infected with an infectious disease is input to the information processing device 12.

[0041] The notification unit 48 notifies, for the first area, a cleaning request for the object whose identification information is included in the first log data 32 at a timing predetermined as the timing when the object can be cleaned. Examples of this timing include break times such as lunch breaks and times between inspections.

[0042] Further, the notification unit 48 notifies, for the second region, the cleaning request for the object indicated by the identification information extracted by the extraction unit 46 at the first timing and the second timing. At this time, the notification unit 48 notifies the cleaning request for the object that has been contacted by a person who has been found to have a positive infectious disease test result and the object that has been approached for a first fixed period or more and has not been cleaned, from the first timing to a time period before the second fixed period. Also, at this time, the notification unit 48 notifies the cleaning request for the object that has been contacted by a person who has been found to satisfy the conditions suspected of being infected with an infectious disease and the object that has been approached for a first fixed period or more and has not been cleaned, from the second timing to a time period before the second fixed period. As the second fixed period in this case, a period determined according to the maximum remaining period of the pathogen of the infectious disease can be applied for each material of the object. For example, assuming COVID-19 as the infectious disease, the maximum remaining period of the virus, which is the pathogen, is said to be 3 hours on the surface of copper and 72 hours on the surface of plastic. Thus, the second fixed period may be the maximum remaining period of the pathogen of the infectious disease for each material of the object, or a period obtained by adding a margin to the maximum remaining period of the pathogen of the infectious disease. Also, when a plurality of materials are used for the object, the second fixed period may be determined according to the material with the longest maximum remaining period among the plurality of materials.

[0043] With reference to FIG. 5, an example of the notification process for the cleaning request of the object at the first timing will be described. The horizontal axis in FIG. 5 represents time, and the circles represent the objects whose identification information is included in the second log data 34, and the timings when a person who has been found to have a positive infectious disease test result has contacted or approached the object for a first fixed period or more. Also, the leftward dashed arrow in FIG. 5 represents the second fixed period. Also, in FIG. 5, the timing of cleaning is also shown for the objects for which cleaning has been performed.

[0044] In the example of FIG. 5, for objects A, B, and E, since the timing when a person with a positive infectious disease test result made contact or was in close proximity for a first predetermined period or longer was before the second predetermined period from the first timing, no cleaning request is notified. Also, for object D, although the timing when a person with a positive infectious disease test result made contact or was in close proximity for a first predetermined period or longer was within the second predetermined period from the first timing, since cleaning was performed after the contact or close proximity, no cleaning request is notified. Further, for objects C and F, since the timing when a person with a positive infectious disease test result made contact or was in close proximity for a first predetermined period or longer was within the second predetermined period from the first timing and cleaning has not been performed, a cleaning request is notified. In FIG. 5, an example at the first timing is shown, but the same applies to the second timing. Whether an object has been cleaned can be determined, for example, by associating a flag indicating whether it has been cleaned with the identification information of the object.

[0045] In this embodiment, the notification unit 48 notifies a cleaning request by sending a message of the cleaning request to a portable information terminal held by a person in charge predetermined in advance as the administrator of the object. Examples of such a message include, for example, a message such as "Please clean object A installed at location A." Further, the notification unit 48 may notify a cleaning request by sending an e-mail of the cleaning request to the e-mail address of a person in charge predetermined in advance as the administrator of the object. Also, the notification unit 48 may notify a cleaning request by blinking an LED (Light Emitting Diode) lamp provided on the object. Further, when a display device is provided on the object, the notification unit 48 may notify a cleaning request to be displayed on the display device. Also, a combination of these multiple notification methods may be used.

[0046] The deletion unit 50 deletes, at regular timings such as once a day, the logs included in the first log data 32 and the second log data 34 that have passed the upper limit value of the incubation period of the pathogen of the infectious disease since the log acquisition time. When a plurality of infectious diseases are assumed, the deletion unit 50 deletes the logs included in the first log data 32 and the second log data 34 that have passed the longest incubation period among the incubation periods of the infectious diseases since the log acquisition time. Note that the deletion unit 50 may delete the logs that have passed a period obtained by adding a margin to the incubation period of the pathogen of the infectious disease since the log acquisition time.

[0047] Next, with reference to FIGS. 6 to 10, the operation of the information processing apparatus 12 according to the present embodiment will be described. By the CPU 20 executing the information processing program 30, the log storage process shown in FIG. 6, the first cleaning request notification process shown in FIG. 7, the second cleaning request notification process shown in FIG. 8, the third cleaning request notification process shown in FIG. 9, and the log deletion process shown in FIG. 10 are executed. The log storage process shown in FIG. 6 is executed, for example, every time the information processing apparatus 12 receives a log transmitted from the log acquisition apparatus 14. The first cleaning request notification process shown in FIG. 7 is executed, for example, at a timing predetermined as a timing when an object can be cleaned, such as during the lunch break and between inspections. The second cleaning request notification process shown in FIG. 8 is executed, for example, at the first timing described above. The third cleaning request notification process shown in FIG. 9 is executed, for example, at the second timing described above. The log deletion process shown in FIG. 10 is executed, for example, at regular timings such as once a day.

[0048] In step S10 of FIG. 6, the acquisition unit 40 acquires the log transmitted from the log acquisition apparatus 14 via the network I / F 25. In step S12, the determination unit 42 determines whether or not the classification of the log acquired in step S10 is "approach". If this determination is an affirmative determination, the process proceeds to step S14.

[0049] In step S14, the determination unit 42 determines whether the period from the "start date and time" to the "end date and time" of the log obtained in step S10 is equal to or longer than a first fixed period. If this determination is an affirmative determination, the process proceeds to step S16. Also, if the determination in step S12 is a negative determination, the process proceeds to step S16.

[0050] In step S16, the determination unit 42 uses the position information included in the log obtained in step S10 to determine whether the installation position of the object indicated by the identification information of the object included in the log is within a first area. If this determination is an affirmative determination, the process proceeds to step S18. In step S18, the storage control unit 44 performs control to store the log obtained in step S10 in the first log data 32 of the storage unit 22. When the process of step S18 ends, the log storage process ends.

[0051] On the other hand, if the determination in step S16 is a negative determination, the process proceeds to step S20. In step S20, the storage control unit 44 performs control to store the log obtained in step S10 in the second log data 34 of the storage unit 22. When the process of step S20 ends, the log storage process ends. Also, if the determination in step S14 is a negative determination, the log storage process ends.

[0052] In step S30 of FIG. 7, as described above, the notification unit 48 notifies a cleaning request for the object whose identification information is included in the first log data 32. When the process of step S30 ends, the first cleaning request notification process ends.

[0053] In step S40 of FIG. 8, the extraction unit 46 extracts the identification information of the objects contacted by the person who has been found to have a positive test result for an infectious disease from the second log data 34. Further, the extraction unit 46 also extracts the identification information of the objects approached by the person who has been found to have a positive test result for an infectious disease from the second log data 34. In step S42, as described above, the extraction unit 46 notifies the cleaning requirement for the object indicated by the identification information extracted in step S40. When the process of step S42 ends, the second cleaning requirement notification process ends.

[0054] In step S50 of FIG. 9, the extraction unit 46 extracts the identification information of the objects contacted by the person who has been found to meet the conditions suspected of being infected with an infectious disease from the second log data 34. Further, the extraction unit 46 also extracts the identification information of the objects approached by the person who has been found to meet the conditions suspected of being infected with an infectious disease from the second log data 34. In step S52, as described above, the extraction unit 46 notifies the cleaning requirement for the object indicated by the identification information extracted in step S50. When the process of step S52 ends, the third cleaning requirement notification process ends.

[0055] In step S60 of FIG. 10, as described above, the deletion unit 50 deletes the logs in the first log data 32 and the second log data 34 that have passed the upper limit value of the incubation period of the pathogen of the infectious disease from the time of log acquisition. When the process of step S60 ends, the log deletion process ends.

[0056] As described above, according to the present embodiment, since the notification of the cleaning requirement of the object is appropriately performed, the spread of infectious diseases through the object can be suppressed.

[0057] In the above embodiment, the notification unit 48 may further notify, at the first timing, information representing a person who has contacted or approached within a first predetermined period or more an object including identification information in the log data 34 after it has been determined that the test result for an infectious disease is positive, to an object that has not been cleaned, regarding a person who has contacted the object within a second predetermined period from that timing. In this case, the notification unit 48 notifies, for example, a message recommending disinfection such as "Please wash your hands because you have contacted an object that may be contaminated." to the portable information terminal possessed by the person. Also, the notification unit 48 may further notify, at the second timing, information representing a person who has contacted or approached within a first predetermined period or more an object including identification information in the log data 34 after it has been determined that the test result for an infectious disease is positive, to an object that has not been cleaned, regarding a person who has contacted the object within a second predetermined period from that timing.

[0058] Referring to FIG. 11, an example of the notification process for the cleaning request of an object at the first timing in this exemplary form will be described. The horizontal axis in FIG. 11 represents time, and the circles represent the timing when a person who has been determined to have a positive test result for an infectious disease has contacted or approached within a first predetermined period or more an object including identification information in the second log data 34. Also, the leftward dashed arrow and the rightward dashed arrow in FIG. 11 represent the second predetermined period. Also, in FIG. 11, the timing of cleaning is also shown for the objects that have been cleaned. Also, the triangles in FIG. 11 represent the people who have contacted the objects in the same row. For example, person A in FIG. 11 represents that person A has contacted object A after the cleaning of object A has been performed.

[0059] In the example of FIG. 11, since Person A is in contact with Object A after the cleaning of Object A has been carried out, Person A is not a target for notification. Also, since Person B is in contact with Object B within a second predetermined period after a person who has been found to have a positive infectious disease test result has come into contact with or been in close proximity to Object B for a first predetermined period or more, Person B is a target for notification. Further, since Person C is in contact with Object E after the elapse of a second predetermined period after a person who has been found to have a positive infectious disease test result has come into contact with or been in close proximity to Object E for a first predetermined period or more, Person C is not a target for notification. Although FIG. 11 shows an example at the first timing, the same applies at the second timing.

[0060] Also, in the above-described embodiment, the notification unit 48 may further notify a cleaning request for an object that has come into contact with an object that is a target for a cleaning request and for which cleaning has not been performed at the first timing and the second timing. In this exemplary form, as shown in FIG. 12 as an example, a cleaning request for Object G that has come into contact with Object F, which is a target for a cleaning request and for which cleaning has not been performed, is also notified. Contact between objects occurs, for example, in a situation where the objects are stored in a stacked state.

[0061] Also, in the above-described embodiment, the notification unit 48 may notify a cleaning request while varying the message between the first timing and the second timing. In this case, at the first timing, the notification unit 48 notifies a cleaning request instructing cleaning, such as a message like "Since this is an object that a person with a positive infectious disease test result has come into contact with or been in close proximity to, please clean it." On the other hand, in this case, at the second timing, the notification unit 48 notifies a cleaning request with a warning level lower than that at the first timing. Specifically, in this case, the notification unit 48 notifies a cleaning request recommending cleaning, such as a message like "Since this is an object that a person suspected of being infected with an infectious disease has come into contact with or been in close proximity to, cleaning is recommended."

[0062] Also, in the above embodiment, the determination unit 42 may make the first fixed period variable according to the protection state of a person. In this case, for example, the determination unit 42 may be configured to make the first fixed period longer for a person wearing a mask than for a person not wearing a mask. Whether a person is wearing a mask or not can be determined, for example, by performing image analysis processing on an image obtained by photographing the person with a camera.

[0063] Also, in the above embodiment, the determination unit 42 may make the first fixed period variable according to the disinfection state of a person. In this case, for example, the determination unit 42 may be configured to make the first fixed period shorter for a person with insufficient handwashing than for a person with sufficient handwashing. Whether handwashing is sufficient or not can be determined, for example, by the function of a wearable terminal such as a smartwatch. For example, whether handwashing is sufficient or not is determined based on whether the handwashing period is equal to or longer than a predetermined threshold.

[0064] Also, in the above embodiment, similar to the log with the category "proximity", for the log with the category "contact", control may be performed to store in the storage unit 22 a log in which the period from the "start date and time" to the "end date and time" is equal to or longer than a fixed period. In this case, a log with the category "contact" and a period from the "start date and time" to the "end date and time" shorter than the fixed period is discarded. The fixed period in this case may be the same as the first fixed period or may be shorter than the first fixed period.

[0065] Also, in the above-described embodiment, for example, as the hardware structure of a processing unit that executes various processes such as the acquisition unit 40, the determination unit 42, the memory control unit 44, the extraction unit 46, the notification unit 48, and the deletion unit 50, the following various processors can be used. As described above, in addition to the CPU, which is a general-purpose processor that executes software (program) and functions as various processing units, the above various processors include a programmable logic device (PLD), such as an FPGA (Field Programmable Gate Array), which is a processor whose circuit configuration can be changed after manufacturing, and a dedicated electric circuit, etc., which is a processor having a circuit configuration designed specifically to execute specific processes, such as an ASIC (Application Specific Integrated Circuit).

[0066] One processing unit may be composed of one of these various processors, or may be composed of a combination of two or more processors of the same type or different types (for example, a combination of multiple FPGAs, or a combination of a CPU and an FPGA). Also, a plurality of processing units may be composed of one processor.

[0067] As an example of configuring a plurality of processing units with one processor, firstly, as represented by computers such as clients and servers, there is a form in which one processor is configured by a combination of one or more CPUs and software, and this processor functions as a plurality of processing units. Secondly, as represented by a system on chip (SoC), etc., there is a form in which a processor that realizes the functions of the entire system including a plurality of processing units with one IC (Integrated Circuit) chip is used. Thus, as a hardware structure, the various processing units are configured using one or more of the above various processors.

[0068] Furthermore, as the hardware structure of these various processors, more specifically, circuitry combining circuit elements such as semiconductor elements can be used.

[0069] In addition, in the above embodiment, the mode in which the information processing program 30 is pre-stored (installed) in the storage unit 22 has been described, but the present invention is not limited to this. The information processing program 30 may be provided in a form recorded on a recording medium such as a CD-ROM (Compact Disc Read Only Memory), a DVD-ROM (Digital Versatile Disc Read Only Memory), and a USB (Universal Serial Bus) memory. Further, the information processing program 30 may be in a form downloaded from an external device via a network.
