Description

[Technical Field]

[0001] The present invention relates to a message distribution device, a message distribution method, and a message distribution program for distributing a notification message related to the security of a terminal. [Background technology]

[0002] In recent years, cyber attacks using malware have become more sophisticated, causing a large number of damages due to spam emails or unauthorized access, etc. In this situation, it is becoming increasingly important to implement security measures on the devices that users use.

[0003] Patent Document 1 proposes a device that notifies users of necessary information from security information collected from trusted sites, such as the current patch application status, etc. This allows users to obtain security information in a timely manner and, by applying patches in accordance with the patch information, they can always use their hosts safely.

[0004] Patent Document 2 proposes a device that determines whether there is a failure on the server side when notifying users of software updates, and notifies them when there is no failure. This allows users to update without overlapping with server failures.

[0005] On the other hand, generally, when updating the OS or other software, even if the update is set to automatic, it is often necessary to restart the device, so the user must take measures themselves. For this reason, it is important to have measures to encourage users to take action (to take measures).

[0006] Non-patent document 1 describes a method (self-reevaluation) that encourages the initiation of a behavior by imagining oneself performing the behavior and reevaluating it, and a method (reinforcement management) that encourages the maintenance of a behavior by giving a reward for continuing the behavior.

[0007] Non-Patent Document 2 shows that by presenting an image of a dog to the user and attracting their "cuteness," they can draw their attention to a security warning. In this case, "cuteness" is the reward, encouraging attention.

[0008] Non-Patent Document 3 proposes a method for encouraging OS updates by changing one's own facial image. By updating the OS, one's facial image is beautified to an ideal image, while by not updating the OS, one's facial image becomes less ideal. In this case, the beautification of one's own facial image corresponds to a reward, which has the effect of encouraging updates.

[0009] Non-Patent Document 4 proposes a method for promoting OS updates by utilizing nudges of "others' approval" and "others' imitation." Here, "others' approval" refers to having others approve of an action one has taken, leading to further action. "Others' imitation" refers to taking action by imitating the actions of others. Demonstration results using SNS have shown that other's approval is more effective in encouraging OS updates than imitation.

[0010] Non-Patent Document 5 shows that there is a type of tourist behavior called "oshi consumption," which exists in a style that differs from general tourist behavior in terms of who travels with whom and the amount of spending, and is widely practiced by people of all genders and ages. Here, "oshi" refers to idols, anime characters, etc. that users have a favorable impression of. [Prior art documents] [Patent documents]

Summary of the Invention [Problem to be solved by the invention]

[0013] Patent Document 1 describes a technology that judges the reliability of an information provider site and the risk level of security information and notifies appropriate information, but since the information provided is the same message for all users, it may not improve users' awareness of taking security measures themselves. Like Patent Document 1, Patent Document 2 also takes into consideration the state on the server side, but the notification timing does not take into consideration the user's awareness or the work content, so there is a problem that the effect of improving the update rate is small. The psychological effects cited in Non-Patent Document 1 have not been used appropriately to promote security measures, nor have they been appropriately personalized for each user. The method described in Non-Patent Document 2 has the problem that the image of the dog presented is the same every time, so the user becomes accustomed to the warning, and the effect is not sustained. The method described in Non-Patent Document 3 can prevent habituation by changing one's own face, but since it uses the user's face, there are problems in terms of feasibility and privacy. The method mentioned in Non-Patent Document 4 requires approval from an unspecified number of people, and therefore it is necessary to control the actions of an unspecified number of people. One possible solution to this problem is to implement a bot (automatic response program), but this is expected to have different effects from those of an actual person, making it difficult to apply. The method described in Non-Patent Document 5 shows that users can take action for their favorites. The effect of favorites has not been used to promote security measures until now.

[0014] The present invention aims to provide a message distribution device, a message distribution method, and a message distribution program that utilize rewards resulting from the psychological effects of a favorite idol and the leveling of those rewards to promote security measures and improve the implementation rate of security measures. [Means for solving the problem]

[0015] The message delivery device of the present invention comprises: a favorite image registration unit that registers, for each user, at least one image of a favorite idol that the user likes; a reward creation unit that generates one or more images and / or videos of the favorite idol that the user finds pleasing based on pre-registered reward level rules and the user's reward level, and creates display data with the generated image and / or video of the favorite idol that is pleasing; a terminal information acquisition unit that acquires terminal information including the implementation status of security measures on the user's terminal; a message creation unit that determines, based on the terminal information, items of security measures that have not yet been implemented, and creates a message requesting the implementation of those items; a message delivery unit that delivers the created message to the user's terminal; and a message response acquisition unit that acquires a response to the delivered message including whether or not the items have been implemented, and the message response acquisition unit determines the user's reward level based on at least whether or not the items have been implemented, and delivers the display data created by the reward creation unit to the user's terminal in accordance with the determined reward level as a reward for the implemented security measures.

[0016] The message delivery device may further include a conversation processing unit that converses with the favorite character registered by the favorite character image registration unit.

[0017] The message distribution device includes a questionnaire distribution unit that distributes a questionnaire including items asking about the user's implementation status or level of interest in security measures, a questionnaire result acquisition unit that acquires responses to the questionnaire, and a judgment unit that determines the user's behavioral change stage regarding security measures based on the responses to the questionnaire, the terminal information, and responses to past messages, and the message response acquisition unit may determine the reward level of the user based on the user's behavioral change stage and / or the number of times the items are implemented.

[0018] The favorite image registration unit may register, for each of the user's multiple software programs, different favorite images that the user has a favorable impression of.

[0019] The message delivery method of the present invention comprises: a favorite image registration step for registering, for each user, at least one image of a favorite character that the user likes; a reward creation step for generating one or more images and / or videos of the favorite character that the user finds pleasing based on pre-registered reward level rules and the user's reward level, and creating display data with the generated images and / or videos of the favorite character that are pleasing the user; a terminal information acquisition step for acquiring terminal information including the implementation status of security measures on the user's terminal; a message creation step for determining, based on the terminal information, items of security measures that have not been implemented and creating a message requesting the implementation of those items; a message delivery step for delivering the created message to the user's terminal; and a message response acquisition step for acquiring a response to the delivered message including whether or not the items have been implemented, wherein the message response acquisition step determines the user's reward level based on at least whether or not the items have been implemented, and delivers the display data created in accordance with the determined reward level to the user's terminal as a reward for the implemented security measures.

[0020] A message distribution program according to the present invention causes a computer to function as the message distribution device. [Effects of the Invention]

[0021] According to the present invention, by utilizing the rewards resulting from the psychological effects of the favorite idol and the leveling of those rewards, it is possible to promote security measures and improve the implementation rate of security measures.

[0023] An example of an embodiment of the present invention will be described below. The message distribution device of this embodiment notifies users of messages that use the psychological characteristics and reward levels they feel toward their favorite idol, thereby encouraging them to take security measures, such as updating the OS or other software on their device (terminal), and encouraging them to continue that behavior. Although this embodiment can be applied to various security measures such as updating an OS (applying a correction patch) or updating other software, the following mainly illustrates the case of updating an OS.

[0024] FIG. 1 is a diagram showing the configuration of a management system 1 according to this embodiment. The management system 1 includes an information management server 10 (message distribution device) equipped with a database, and a user terminal 20, to which management software is distributed.

[0025] The management system 1 executes rule registration processing (1), favorite image registration processing (2), conversation processing (3), reward creation processing (4), terminal information acquisition processing (5), survey distribution processing (6), survey result acquisition processing (7), behavior change stage determination processing (8), message creation processing (9), message distribution processing (10), and message response acquisition processing (11) by operating in cooperation with the information management server 10 and the software of the user terminal 20.

[0026] As a result, the information management server 10 manages messages and their distribution conditions, and distributes to the user terminal 20 a message that prompts the user terminal 20 to take necessary security measures (OS update) in accordance with the terminal information. In this case, the information management server 10 utilizes the approval of a specific small number of people, known as the "oshi," as a psychological characteristic of the user, and when an OS update is implemented after a notification message is sent to encourage an OS update, it presents a reward containing an image or video of the "oshi" looking pleased, thereby utilizing the psychological effect (enhancing effect) of approval from the "oshi," thereby improving the OS update rate and maintaining the improved update rate. Here, the enhancing effect is the effect of extrinsic motivation increasing intrinsic motivation and raising motivation (see, for example, Kimura Michihiro: The Effect of Rewards on Intrinsic Motivation, Hirosaki University Master's Thesis (2008)). Furthermore, in the message distribution method of this embodiment, as described below, the psychological effect (enhancing effect) of approval from an idol is utilized, and by changing the idol's image and / or video, the OS update rate is improved.

[0027] FIG. 2 is a diagram showing the functional configuration of the information management server 10 in this embodiment. The information management server 10 is an information processing device (computer) that includes a control unit 11, a storage unit 13, as well as input / output devices and communication devices for various data.

[0028] The control unit 11 is a part that controls the entire information management server 10, and realizes each function in this embodiment by appropriately reading and executing various programs stored in the storage unit 13. The control unit 11 may be a CPU.

[0029] The storage unit 13 is a storage area for various programs for causing the hardware group to function as the information management server 10, various data, etc., and may be a ROM, RAM, flash memory, hard disk drive (HDD), or the like. Specifically, the storage unit 13 stores various databases in addition to a program (message distribution program) for causing the control unit 11 to execute each function of this embodiment.

[0030] The control unit 11 includes a rule registration unit 111, a favorite image registration unit 112, a conversation processing unit 113, a reward creation unit 114, a terminal information acquisition unit 115, a survey distribution unit 116, a survey result acquisition unit 117, a stage determination unit 118, a message creation unit 119, a message distribution unit 120, and a message response acquisition unit 121.

[0031] The rule registration unit 111 is a functional unit that performs the rule registration process (1). Specifically, the rule registration unit 111 receives terminal distribution conditions 131 for messages encouraging the implementation of security measures as distribution rules based on knowledge obtained from, for example, survey results, etc., in advance from the system administrator directly or via the system administrator's terminal, and registers the conditions in the database of the storage unit 13. Knowledge gained from survey results, etc., may include, for example, the stage of behavioral change determined based on the user's interest, concern, and awareness of security measures, as well as the implementation status of measures, or appropriate delivery timing based on personality, risk awareness, and the work status on the user terminal 20.

[0032] Here, the behavioral change stage represents a gradual progression from a state of being indifferent to implementing security measures to a state of continuously implementing them. For example, the stages are defined as follows, and it is determined which stage each user is in. Indifferent stage: No interest or concern in security measures, and no understanding of current available security measures. Interest stage: People are interested in security measures or are aware of the security measures currently available, but do not want to take them. Preparation stage: You want to take all the security measures you can currently take, but you are not implementing the security measures that you should be taking yourself. Action stage: You occasionally implement necessary security measures yourself, but do not do so consistently. Maintenance stage: You continue to implement the necessary security measures yourself.

[0033] Furthermore, the rule registration unit 111 registers, as a message 132 in the database of the storage unit 13, a message to be notified according to the type of security measure and the user's attributes such as the behavioral change stage.

[0034] When the terminal delivery conditions 131 and the message 132 are registered, the rule registration unit 111 automatically initializes delivery rules 133 suited to the attribute information including the behavioral change stage of each user and the type of security measure.

[0035] Furthermore, the rule registration unit 111 determines multiple elements (message text, UI design, delivery timing, etc.) that define the characteristics of the message to be delivered individually based on the attribute information of each user (user terminal 20), and records them as a terminal delivery setting log 134 in the database of the memory unit 13.

[0036] Thereafter, the rule registration unit 111 records the terminal distribution setting log 134 each time it determines a new terminal distribution setting in accordance with a predetermined rule based on the status of each user terminal 20 obtained by the terminal information acquisition process (5) or the message response acquisition process (11) described below.

[0037] Furthermore, the rule registration unit 111 may receive rules for reward levels (reward rules) in advance from a system administrator directly or via the system administrator's terminal based on known motivation theories (for example, valence (Victor H. Vroom: Work and Motivation, Wiley, 1964.) or Maslow's hierarchy of needs), and register the rules in the reward rules 139 of the storage unit 13. Furthermore, since there is a possibility that different users have different perceptions of reward rules, the rule registration unit 111 may conduct a survey of users, quantify the responses obtained, generate reward rules, and register the rules in the reward rules 139.

[0038] Furthermore, as will be described later, the rule registration unit 111 may receive rules for providing rewards (reward provision rules) in advance from the system administrator directly or via the system administrator's terminal according to the user's behavioral change stage and / or the number of OS updates, and register the rules in the reward provision rules 140 in the memory unit 13.

[0039] The recommended image registration unit 112 is a functional unit that performs the recommended image registration process (2), and for each user who uses the services of the management system 1, registers at least one image of a recommended character that the user likes. Specifically, the favorite image registration unit 112 acquires in advance copyright-free images of characters from games, anime, and the like, or idols, etc., provided by an external server, and stores them as favorite images 135 in the storage unit 13. The favorite image registration unit 112 displays a list of favorite images stored in favorite images 135 on a display unit (not shown) such as a liquid crystal display of the user terminal 20, and registers an image selected by the user as a favorite image. Alternatively, when a user selects an image of a character or the like created by the user himself, the favorite image registration unit 112 may upload it from the user terminal 20 and register it as a favorite image in the favorite image 135 of the memory unit 13.

[0040] The conversation processing unit 113 is a functional unit that performs conversation processing (3) to converse with the favorite character registered by the favorite character image registration unit 112. In order to converse with the favorite character, the conversation processing unit 113 may receive anticipated questions and answers in advance from the system administrator directly or via the system administrator's terminal, and register them in the database of the storage unit 13. Alternatively, the conversation processing unit 113 may use an AI tool such as chatGPT (registered trademark) to allow the user of the user terminal 20 to have a conversation with their favorite idol.

[0041] The reward creation unit 114 is a functional unit that handles the reward creation process (4), and generates one or more images and / or videos of the user's favorite character that are happy to the user based on the registered favorite character image, based on the pre-registered reward level rules and the user's reward level, and creates display data that includes the generated images and / or videos of the favorite character that are happy to the user. Specifically, the reward creation unit 114 may use, for example, existing software (for example, a processing tool such as SNOW (registered trademark)) to automatically process the registered favorite image or process it in response to user input, in accordance with reward level rules registered in advance by a system administrator, i.e., reward rules 139, to generate one or more images and / or videos of the favorite character looking happy. The reward creation unit 114 creates display data in accordance with the reward rules 139, to which the generated images and / or videos of the favorite character looking happy have been added. That is, the display data created in accordance with the reward rules (reward level rules) in this embodiment is as follows, as shown in Figures 3A to 3D: Reward level 1 is presented the first time. Level 1: An objective message conveying that your favorite idol is happy Level 2: Thank you message from your favorite idol Level 3: A photo of your favorite person looking happy (e.g., smiling) + a thank you message from your favorite person Level 4: Images that show that your favorite is happy and recognizes you (the user), or exclusive videos that can be viewed by updating your OS The reward rules 139 have four reward levels, but are not limited to this. For example, the reward rules 139 may have five or more reward levels. Alternatively, the system administrator may manually create the display data for the rewards.

[0042] The terminal information acquisition unit 115 is a functional unit that performs the terminal information acquisition process (5), and periodically acquires terminal information such as the OS version and patch application status of the user terminal 20 through the software of the user terminal 20 in order to understand the implementation status of security measures by the user. The acquired terminal information is recorded as a terminal information log 136 in the database of the storage unit 13.

[0043] The questionnaire distribution unit 116 is a functional unit that performs the questionnaire distribution process (6), and distributes to the user terminal 20 a questionnaire that includes questions about the implementation status of security measures by the user or the degree of interest.

[0044] The survey result acquisition unit 117 is a functional unit that performs the survey result acquisition process (7) and acquires responses to the survey from the user terminal 20. The acquired information is recorded as a survey log 137 in the database of the storage unit 13.

[0045] The stage determination unit 118 is a functional unit that performs the behavioral change stage determination process (8), and determines the user's behavioral change stage regarding security measures based on responses to questionnaires, terminal information, and past responses by the user to messages described below.

[0046] The information management server 10 can determine personalized text, UI design, and delivery timing for each behavioral change stage classified in this way, depending on the user's awareness determined from the questionnaire responses and the status of countermeasure implementation. In this embodiment, a reward is presented in response to such a personalized message, utilizing the user's psychological characteristics regarding their favorite.

[0047] The message creation unit 119 is a functional unit that performs the message creation process (9), and determines the security measures (e.g., OS updates) that have not been implemented in the user terminal 20 based on the terminal information log 136 acquired by the terminal information acquisition unit 115, and creates a message requesting the implementation of the determined measures.

[0048] The message delivery unit 120 is a functional unit that performs the message delivery process ( 10 ), and delivers the message created by the message creation unit 119 to the user terminal 20 .

[0049] The message response acquisition unit 121 is a functional unit that performs the message response acquisition process (11), and acquires a response from the user terminal 20 in response to the message delivered by the message delivery unit 120, including whether or not the unimplemented security measures have been implemented. The contents of the message delivered to the user terminal 20 and the reply results are recorded in the database of the storage unit 13 as a message delivery log 138.

[0050] FIG. 4 is a diagram illustrating an example of a message display screen in this embodiment. Here, a dialog box is displayed with an image of the user's favorite character, a message urging the user to update their OS due to a security update, and buttons to "Update now" and "Update later." The message response acquisition unit 121 acquires whether or not security measures have been implemented in response to the message delivered to the user, that is, whether "Update now" or "Update later" was selected (which button was pressed). If "Update now" is selected, the update program is applied to the user terminal 20, and if "Update later" is selected, the message is delivered again at the same timing, for example, after a certain period of time has elapsed.

[0051] 4, when an OS update becomes possible, the conversation processing unit 113 may display, through a conversation with the bot, a message indicating that the bot has made it possible to update the OS as a security measure, along with buttons for "Update now" and "Update later," on the display unit (not shown) of the user terminal 20. Furthermore, the conversation processing unit 113 may display, along with the conversation, an image or video of the bot according to the user's behavioral change stage, the number of updates, etc. This allows users to proactively respond to security measures such as OS updates in a more natural way through conversations with their favorite idols, which can promote long-term OS updates. Also, the information management server 10 can improve users' familiarity with OS updates and maintain the update rate.

[0052] The message response acquisition unit 121 refers to the message delivery log 138 in the storage unit 13 and determines the reward level to be provided depending on the user's behavioral change stage and the number of updates made by the user. FIG. 5 is a first flowchart showing the process of determining a reward level according to a user's behavioral change stage by the message response acquisition unit 121 in this embodiment. Here, the reward level of the target user is determined according to the behavioral change stage of the user.

[0053] In step S1, the message response acquisition unit 121 determines whether the user's behavioral change stage is the action stage or later. If the determination is YES, the process proceeds to step S2, and if the determination is NO, the process proceeds to step S3.

[0054] In step S2, the message response acquisition unit 121 increases the user's reward level by 1. The message response acquisition unit 121 refers to the reward provision rules 140 in the storage unit 13, and delivers, as a reward, to the user terminal 20 of the user, one of the display data in Figures 3A to 3D corresponding to the user's reward level that has been increased by 1.

[0055] In step S3, the message response acquisition unit 121 does not change the user's reward level. The message response acquisition unit 121 refers to the reward provision rules 140 in the storage unit 13, and delivers one of the display data shown in Figures 3A to 3D corresponding to the same reward level as a reward to the user terminal 20 of the user. In this case, it is preferable that the information management server 10 make the message text, images, and videos in the display data slightly different from those delivered previously, thereby preventing the user from becoming accustomed to security measures.

[0056] FIG. 6 is a second flowchart showing the process of determining a reward level according to the number of updates by the message response acquisition unit 121 in this embodiment. Here, the reward level of the user is determined according to the number of updates of the target user.

[0057] In step S11, the message response acquisition unit 121 determines whether the user's OS has been updated two or more times. If the determination is YES, the process proceeds to step S12, and if the determination is NO, the process proceeds to step S13.

[0058] In step S12, the message response acquisition unit 121 increases the user's reward level by 1. The message response acquisition unit 121 refers to the reward provision rules 140 in the storage unit 13, and delivers, as a reward, to the user terminal 20 of the user, one of the display data in Figures 3A to 3D corresponding to the user's reward level that has been increased by 1.

[0059] In step S13, the message response acquisition unit 121 does not change the user's reward level. The message response acquisition unit 121 refers to the reward provision rules 140 in the storage unit 13, and delivers one of the display data shown in Figures 3A to 3D corresponding to the same reward level as a reward to the user terminal 20 of the user. In this case, it is preferable that the information management server 10 make the message text, images, and videos in the display data slightly different from those delivered previously, thereby preventing the user from becoming accustomed to security measures.

[0060] FIG. 7 is a third flowchart showing the process of determining a reward level according to the user's behavior change stage and the number of updates by the message response acquisition unit 121 in this embodiment. Here, the reward level of the target user is determined according to the behavioral change stage and number of updates of the user.

[0061] In step S21, the message response acquisition unit 121 determines whether the user's behavioral change stage is the action stage or later. If the determination is YES, the process proceeds to step S23, and if the determination is NO, the process proceeds to step S22.

[0062] In step S22, the message response acquisition unit 121 determines whether the user's OS has been updated two or more times. If the determination is YES, the process proceeds to step S23, and if the determination is NO, the process proceeds to step S24.

[0063] In step S23, the message response acquisition unit 121 increases the user's reward level by 1. The message response acquisition unit 121 refers to the reward provision rules 140 in the storage unit 13, and delivers, as a reward, to the user terminal 20 of the user, one of the display data in Figures 3A to 3D corresponding to the user's reward level that has been increased by 1.

[0064] In step S24, the message response acquisition unit 121 does not change the user's reward level. The message response acquisition unit 121 refers to the reward provision rules 140 in the storage unit 13, and delivers one of the display data shown in Figures 3A to 3D corresponding to the same reward level as a reward to the user terminal 20 of the user. In this case, it is preferable that the information management server 10 make the message text, images, and videos in the display data slightly different from those delivered previously, thereby preventing the user from becoming accustomed to security measures.

[0065] According to this embodiment, the information management server 10 delivers display data of an image or video of the user's favorite character being happy to the user as a reward to the user terminal 20, depending on whether the OS has been updated in response to a message encouraging the user to implement security measures on the user terminal 20 and / or the user's stage of behavioral change. This allows the information management server 10 to utilize the rewards resulting from the psychological effects of the favorite idol and the leveling of those rewards to promote security measures and improve the implementation rate of security measures. Furthermore, the information management server 10 can improve the OS update rate and maintain the improved update rate by using the favorite as the specific minority and utilizing the psychological effect (enhancing effect) recognized by the favorite.

[0066] <Variation 1> The information management server 10 increases the user's reward level according to the user's behavioral change stage and / or the number of updates, but is not limited to this. For example, if the user does not implement security measures, the information management server 10 may lower the user's reward level or distribute display data of an image and / or video of the user's favorite character looking sad. Since users prefer images of their favorite idols that show them happy to images that show them sad, this will not only encourage users to take measures, but also encourage them to continue taking measures.

[0067] <Variation 2> Although the information management server 10 has registered an image of one favorite character, the present invention is not limited to this. For example, the information management server 10 may register different favorite character images for each of a plurality of pieces of software. By doing so, users will be more likely to feel the need to take security measures when they receive update notifications from each of their favorite software programs, compared to when they only have one favorite software program. In other words, if users only received update messages from one favorite software program, they would become accustomed to security measures, but by receiving update messages from different favorite software programs for each software program, a synergistic effect is expected in which users' accustomedness to security measures can be reduced. In addition, some users use the same favorite for a long time, while others change favorites frequently in a short period of time. Even for users who frequently change their favorite, changing favorites can further suppress habituation to updates and is expected to improve the rate of continuous updates.

[0068] <Variation 3> The information management server 10 has set the reward level of the reward rule 139 to four stages, but is not limited to this. For example, the information management server 10 may set the reward level of the reward rule 139 to five or more. By doing so, the information management server 10 can promote security measures to users in a more detailed manner and improve the implementation rate of security measures by utilizing the psychological effects and reward levels of the favorite idol.

[0069] <Variation 4> When an OS update becomes possible, the information management server 10 delivers the message shown in Fig. 4 to the user terminal 20, but this is not limiting. For example, when an OS update becomes possible, the information management server 10 may display buttons for "Update now" and "Update later" on the user terminal 20 along with a message that the favorite person has made it possible to update the OS as a security measure through a conversation with the favorite person. Furthermore, the information management server 10 may display an image or video of the favorite person along with the conversation, depending on the user's behavioral change stage, the number of updates, etc. This allows users to proactively respond to security measures such as OS updates in a more natural way through conversations with their favorite idols, which can promote long-term OS updates. Also, the information management server 10 can improve users' familiarity with OS updates and maintain the update rate.

[0070] <Variation 5> The information management server 10 (message response acquisition unit 121) has determined the reward level according to the user's behavioral change stage and / or the number of updates based on any of the first to third flowcharts shown in Figures 5 to 7, but is not limited to this. For example, the information management server 10 (message response acquisition unit 121) may determine the reward level according to the user's behavioral change stage and / or the number of updates based on a flowchart in a form other than the first to third flowcharts.

[0071] Furthermore, this embodiment can, for example, improve the rate at which users themselves implement security measures, thereby contributing to Goal 9 of the United Nations-led Sustainable Development Goals (SDGs), which is to "Develop resilient infrastructure, promote sustainable industrialization and foster innovation."

[0072] Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments. Furthermore, the effects described in the above-described embodiments are merely a list of the most preferable effects resulting from the present invention, and the effects of the present invention are not limited to those described in the embodiments.

[0073] The message distribution method by the management system 1 is realized by software. When realized by software, the programs that make up this software are installed on an information processing device (computer). These programs may be recorded on removable media such as CD-ROMs and distributed to users, or may be distributed by being downloaded to the user's computer via a network. Furthermore, these programs may be provided to the user's computer as a web service via a network without being downloaded. [Explanation of symbols]
