Description

  The present invention relates to an information disclosure support apparatus, an information disclosure support method, and an information disclosure support program used to disclose information related to a user's action history stored in, for example, a memory of a portable terminal or a personal computer.

  In recent years, various sensors have been miniaturized, and it has become possible to constantly sense the state of a user by mounting various sensors in a mobile terminal or a personal computer that a user always has, such as a mobile phone. Also, by generating information on the user's behavior history called life log or experience information based on the data representing the state of daily life of the user obtained by the sensing, and disclosing this life log information to the service provider An attempt has been made by the service provider to provide various services corresponding to the action history to the user.

  However, the life log information often includes information that the user does not want to disclose. For this reason, in order to enable the user to use the service with peace of mind, it is indispensable that the user himself / herself can set permission / inhibition of information disclosure when disclosing life log information.

  Therefore, in order to avoid such a privacy problem, for example, in the field of services that provide content, policy information that defines a procedure for disclosing user attribute information is set and stored in advance, and the content provider When a request for disclosure of user attribute information is sent from the user, it is determined whether or not disclosure of the user attribute information is permitted based on the policy information. A technique for transmitting information has been proposed (see, for example, Patent Document 1).

JP 2005-250779 A

  However, the above-described conventionally proposed technology simply sets disclosure / non-disclosure based on policy information for each type of attribute information such as gender, age, address, place of stay, and accompanying person. It has become. For this reason, there is a problem that it is impossible to set whether to disclose or not to disclose the contents and combinations of the same kind of attribute information, and there is a problem that information disclosure adapted to user needs cannot be performed.

  The present invention has been made paying attention to the above circumstances, and the object of the present invention is to enable disclosure / non-disclosure of individual life log information according to a combination of a plurality of classification elements, thereby further An object of the present invention is to provide an information disclosure support apparatus, an information disclosure support method, and an information disclosure support program capable of realizing fine disclosure / non-disclosure control.

For communication. For example, TCP / IP (Transmission Control Protocol / Internet Protocol) is used as the communication protocol.

  Different sensors 171, 172,... Are connected to the sensor I / Fs 161, 162,. The sensors 171, 172,... Are for measuring history data representing changes in the user's state. For example, a GPS (Global Positioning System) sensor, a pedometer (registered trademark) that measures the number of steps, a user's heart rate and body temperature. It consists of vital sensors that measure etc. Of these, the GPS sensor receives GPS signals transmitted by a plurality of GPS satellites (not shown) under the control of the CPU 11. The sensor I / F to which the GPS sensor is connected obtains sensing data (position data) including time, latitude, and longitude based on the received GPS signals.

  An input device 19 and a display device 20 are connected to the input / output I / F 18. The input device 19 includes a keyboard for a personal computer or PDA (Personal Digital Assistant), for example, and a dial keypad and a plurality of function keys for a mobile phone. In addition, a touch panel or the like can be used. The display device 20 includes a liquid crystal or an organic EL display.

  The data memory 14 is provided with a life log database 141 and a disclosure rule database 142 as databases necessary for carrying out the present invention. The life log database 141 is used to store life log information generated based on the history data obtained by the sensors 171, 172,. The disclosure rule database 142 is used to store a disclosure rule for setting whether to disclose the life log information accumulated in the life log database 141 or not.

  In the program memory 13, history data collection control program 131, life log generation / storage control program 132, disclosure rule setting support control program 133, disclosure determination / An output control program 134 is stored.

  The history data collection control program 131 obtains the sensing data of the sensors 171, 172,... Every time a trigger signal is generated at a constant cycle by a timer or every time a sensing instruction operation is performed by the user on the input device 19. The CPU 11 is caused to execute a process of capturing via the sensor I / F 161, 162,... And storing the captured sensing data in the temporary storage area in the data memory 14 as history data.

  The life log generation / storage control program 132 generates user life log information based on each sensing data (position data, etc.) stored in the temporary storage area in the data memory 14 and stores it in the life log database 141. The CPU 11 is caused to execute the storing process. The life log information is classified according to its type (Channel), information source (Sensor), and occurrence time (Time), or is accumulated in a state that can be classified.

  The disclosure rule setting support control program 133 discloses information for supporting the setting operation when the user sets a disclosure rule that specifies disclosure / non-disclosure for the life log information stored in the life log database 141. The process of displaying on the display device 20 as a rule setting screen, and the process of storing the disclosure rule setting information input by the user with the input device 19 in accordance with the support information displayed on the disclosure rule setting screen in the disclosure rule database 142, The CPU 11 is made to execute.

The process for displaying the information for supporting the setting operation includes a process for accepting input of the type, information source, and time zone of life log information to be set as a disclosure rule, and the input type, information source, and A process of extracting life log information corresponding to the time zone from the life log database 141, a process of calculating an evaluation value indicating the setting priority of the disclosure rule for the extracted life log information, and a life in the order from the highest evaluation value Processing to select log information and display it on the disclosure rule setting screen is included.
Parameters for calculating the evaluation value include “occurrence rate” indicating the occurrence frequency of life log information, “nearest rate” indicating proximity to the time for setting the disclosure rule, and “period” indicating occurrence periodicity The “degree of nature” and the “duration duration” representing the duration of the occurrence duration are defined, and the evaluation value is calculated based on a combination of at least two of these parameters.

  The disclosure determination / output control program 134 discloses the life log information based on the disclosure rule setting information stored in the disclosure rule database 142 when disclosing the life log information accumulated in the life log database 141. Judgment is made. Then, the CPU 11 is caused to execute a process of transmitting the life log information permitted to be disclosed from the communication I / F 15 to the service providing server.

  FIG. 2 is a block diagram showing an information disclosure support function realized by the user terminal UT shown in FIG. In the figure, the history data reception function 21 is realized by the history data collection control program 131 and the sensor I / F 161, 162,..., And the life log generation function 22 and the life log storage function 23 are executed by the life log generation / storage control program 132. Realized. The disclosure rule setting function 27 and the display life log determination function 26 are realized by the disclosure rule setting support control program 133, and the disclosure information addition function 24 and the life log transmission function 25 are the disclosure determination / output control program 134 and the communication I / F 15. It is realized by.

Next, the operation of the information disclosure support apparatus configured as described above will be described.
(1) History data collection to life log information disclosure processing
FIG. 3 is a flowchart showing a processing procedure and processing contents from collection of history data to transmission of life log information to be disclosed.
(1-1) Collection of History Data It is assumed that a trigger signal is generated at a constant cycle by a timer (not shown) or a user inputs a sensing instruction through the input device 19. Then, the CPU 11 activates the history data collection control program 131 in step S11, and performs sensing from the sensors 171, 172,..., Such as a GPS receiver, through the sensor I / F 161, 162,. Capture data. The captured sensing data is stored in a temporary storage unit (not shown) in the data memory 14.
Thereafter, similarly, whenever a trigger signal is generated from the timer or a sensing instruction is input by the user, sensing data such as position information of the own terminal UT is collected and sequentially stored in a temporary storage unit in the data memory 14. Accumulated.

(1-2) Generation and Accumulation of Life Log Information Next, the CPU 11 activates the life log generation / accumulation control program 132 in step S12, and the temporary storage is performed under the control of the life log generation / accumulation control program 132. Sensing data stored in the unit is classified by its type (Channel), information source (Sensor), and generation time (Time), and life log information is generated. And this life log information is memorize | stored in the life log database 141 by step S13.
4 shows an example of the structure of life log information stored in the life log database 141, and FIG. 5 shows a specific description example of life log information stored in the life log database 141.

(1-3) Addition and Transmission of Disclosure Information to Life Log Information When new life log information is stored in the life log database 141, the CPU 11 first executes step S14 under the control of the disclosure determination / output control program 134. The disclosure rule setting information is read from the disclosure rule database 142. Then, based on the read disclosure rule setting information, it is determined in step S15 whether or not the new life log information is a disclosure target. If the new life log information is a disclosure target, the process proceeds from step S16 to step S17. Add information to the effect that disclosure is permitted in the life log information. Specifically, the disclosure / non-disclosure flag assigned to the life log information is set to “disclosure”.

  Next, the CPU 11 reads the life log information in which the disclosure / non-disclosure flag is set to “disclosure” in step S18 from the life log database 141, and reads the read life log information from the communication I / F 15 through a service (not shown). Send to the providing server. If it is determined in step S16 that the new life log information is not a disclosure target, the CPU 11 returns to step S11 while maintaining the disclosure / non-disclosure flag at “non-disclosure”.

(2) Disclosure Rule Setting Support When the user sets a disclosure rule, the CPU 11 executes the following setting support processing according to the disclosure rule setting support control program 133. FIG. 6 is a flowchart showing the processing procedure and processing contents.
(2-1) Designation of Type, Information Source, and Time Zone of Life Log Information Targeted for Disclosure Rule Setting First, in step S21, the CPU 11 reads class data including an instance of life log information from the life log database 141. In step S22, display data for the disclosure rule setting screen is generated, and the generated display data is displayed on the display device 20 via the input / output I / F 18. FIG. 8 shows an example of the disclosure rule setting screen displayed at this time, and shows an input standby state.

In this state, when the user clicks a class selection button displayed on the disclosure rule setting screen, the CPU 11 displays a list of life log information classes, that is, candidates for type (Channel) and information source (Sensor). In this state, it is assumed that the user selects an arbitrary class as a disclosure rule setting target from among the candidate classes displayed in a list. Then, the CPU 11 recognizes this class selection operation in step S23, and determines in step S24 whether or not an instance exists in the selected class. If there is an instance as a result of this determination, the process proceeds to step S25 and waits for the input of a time zone that is to be set as a disclosure rule. If there is no instance in the selected class, the CPU 11 returns to step S22 and repeatedly executes the process for accepting the selection designation of the class to be disclosed in steps S22 to S25.
In this state, it is assumed that the user inputs a time zone to be set on the disclosure rule setting screen. Then, the CPU 11 fetches the input time zone designation information in step S25.

(2-2) Calculation of evaluation value CPU11 calculates the evaluation value showing the setting priority of the disclosure rule regarding each life log information in step S26 next. This evaluation value includes the “occurrence rate” that represents the frequency of occurrence of life log information, the “nearest rate” that represents the proximity to the time when the disclosure rule is set, the “periodicity” that represents the periodicity of the occurrence, Of the “duration time length” representing the length of the duration time, for example, it is calculated by the following formula as a linear combination of “occurrence rate” and “most recent rate”.
Evaluation value = α * incidence + (1-α) * latest rate
However, α is a coefficient that takes a value between 0 and 1, and can be arbitrarily set by the user.

The occurrence rate is defined as a numerical value that takes a value between 0 and 1 calculated by the following equation.
Occurrence rate = number of occurrences of the instance / total number of instances in the class
The most recent rate is defined as a numerical value that takes a value between 0 and 1 calculated by the following equation.
Latest rate = (current time-latest occurrence time of the instance)
/ [Average of (current time-latest occurrence time of each instance in class)]

The “occurrence rate” and “most recent rate” can be obtained by the following processing. FIG. 7 is a flowchart showing an example of the processing procedure and processing contents.
That is, the CPU 11 first reads the format data of the life log information from the life log database 141 in step S41, and determines whether the type (channel name) and the information source (sensor name) included in the format data are existing in step S42, The determination is made at S44. If the type (channel name) is not registered as a result of this determination, the channel and the event extension class are added to the life log database 141 in step S43. If the information source (sensor name) is not registered, the sensor extension class is added to the life log database 141 in step S45.

  Next, the CPU 11 determines in step S46 whether or not an instance with the same name already exists. If it exists, the number of occurrences of the instance is incremented (added by 1) in step S47, and the latest generation time of the instance is updated in step S48. On the other hand, as a result of the determination in step S46, if an instance with the same name does not exist, the CPU 11 adds the entry data in the life log information as an extended class instance in step S49 (Extended Sub- in FIG. 4). See Class). Note that the number of occurrences of the instance and the latest occurrence time are added to the instance to be added at this time.

(2-3) Display of Disclosure Target Instance According to Evaluation Value Next, in step S27, the CPU 11 arranges the instances included in the class in descending order of evaluation value according to the calculated evaluation value and displays them on the disclosure rule setting screen. Let For example, as shown in the disclosure rule setting screen of FIG. 9, “stay place” is selected and designated as the class type and information source, and the time zone is March 1, 2009, 0: 0: 0 to 2009. Assume that 14:30 on March 19 is specified. If it does so, the life log information applicable to the said conditions will be displayed on a target data display column as shown to the figure in order with a high evaluation value.

(2-4) Generation and Storage of Disclosure Rule When the user inputs “condition” and “target” as information indicating the contents of the disclosure rule on the input device 19 in the state where the life log information is displayed, the CPU 11 The input “condition” and “target” are recognized in step S28. At this time, “condition” and “target” are input to check buttons for “condition” and “target” displayed in association with each life log information in the display column of the target data, for example, as shown in FIG. This is done by checking the box. When setting a combination rule, the CPU 11 returns from step S29 to step S22, and repeats the processing of steps S22 to S29.

  Then, when the user presses the “rule setting button” after completing the input of the “condition” and “target”, the CPU 11 generates a disclosure rule in accordance with the input “condition” and “target” in step S30. The generated disclosure rule is stored in the disclosure rule database 142 in step S31. For example, in the example shown in FIG. 10, a disclosure rule “disclose“ bbbbbb ”when“ aaaaaa ”and“ dddddd ”occur simultaneously” is generated and stored.

  That is, disclosure / non-disclosure for specific life log information is set on the condition of a combination of a plurality of events. For this reason, the following effects are exhibited. That is, the evaluation value is a combination of the occurrence rate and the latest rate as described above, and the value is higher as the event that occurs on a daily basis, that is, the higher the occurrence rate, or the event that has recently occurred, that is, the higher the latest rate. growing. Events with high values are events related to the user's daily behavior or recent behavior, and are particularly effective when the disclosed information is used for services such as reminding and recommendation. Also, as the disclosure setting for instances with a high occurrence rate proceeds, instances with a high occurrence rate decrease. For this reason, the influence of the occurrence rate is reduced, and the instance with the highest recent rate is displayed at the top.

  As described above in detail, in this embodiment, according to the disclosure rule setting support program 132, the disclosure rule is set based on the combination of the type and information source of the life log information accumulated in the life log database 141 and the generation time zone. It becomes possible to do. For this reason, it becomes possible to perform more detailed disclosure / non-disclosure control for individual life log information.

Further, in the disclosure rule setting support process, a display rule setting screen is displayed on the display device 20, and the type (Channel), information source (Sensor), and time zone (Time) of the life log information that is the disclosure rule setting target on this setting screen (Period)) is accepted. Then, for the life log information corresponding to the input type (Channel), information source (Sensor), and time zone (Time (Period)), the “occurrence rate” indicating the occurrence frequency and the time when the disclosure rule is set An evaluation value that represents the priority setting of the disclosure rule is calculated based on the “nearest ratio” that represents the proximity to the information, and the life log information is arranged on the display device 20 in the descending order of the calculated evaluation value. ing. For this reason, when setting and inputting a disclosure rule, life log information having a high setting priority of the disclosure rule is automatically selected and presented to the user. For this reason, it becomes possible for the user to preferentially set a disclosure rule for life log information having a high setting priority of the disclosure rule, and the side receiving the disclosure of the life log information is more effective in providing services such as recommendations. It becomes possible to acquire highly useful life log information.
In addition, since the occurrence time zone (Time (Period)) of the life log information is input, the life log information to be set for the disclosure rule can be narrowed down by the time zone. Settings can be made.

  The present invention is not limited to the above embodiment. For example, although the case where date and time is input as a time zone has been described as an example in the embodiment, a desired time zone may be selected and input from attribute information representing a time zone prepared in advance. FIG. 11 shows an example of this, and shows a case where “working time zone” is selected as the time zone attribute information.

  Further, in the above-described embodiment, the case where the evaluation value indicating the setting priority of the disclosure rule is calculated based on the “occurrence rate” and the “most recent rate” has been described as an example. It may be calculated on the basis of “periodicity” and “duration duration” indicating the length of occurrence duration, and further, “occurrence rate”, “most recent rate”, “periodicity degree”, “ All or a combination of two or more of “duration length” may be calculated.

  Furthermore, in the above-described embodiment, the case where the user terminal UT is provided with a user history data collection function and a life log information generation / storage function has been described as an example. However, the present invention is not limited to this, and all or a part of the above functions are provided in a service providing server or a server operated by a company where the user works, and a disclosure request is sent from the user terminal UT to the server as necessary. You may make it acquire historical data or life log information.

Furthermore, the life log information includes information indicating the moving speed or moving distance of the user generated based on the pedometer (registered trademark) sensing data and the user generated based on the vital sensor sensing data. Vital information, safety information, etc. may be included.
In addition, the life log information generation and storage processing procedures and processing contents, the disclosure rule setting support processing procedures and contents, and the like can be variously modified and implemented without departing from the gist of the present invention.

  In short, the present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. Further, various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the embodiment. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, you may combine suitably the component covering different embodiment.
