[0011] Hereinafter, the embodiments will be described in detail with reference to the drawings. <Embodiment> A processing system 1 according to an embodiment of the present disclosure will be described with reference to the drawings. The processing system 1 is a system that calculates a score of an index called "impact on business" for each piece of content to be deleted and determines whether the content can be deleted.

[0012] (Impact on business) First, let's explain the impact on work. The impact on work is calculated based on two factors: "impact on others" and "impact on immediate work."

[0013] (Influence on others) First, the impact on others will be explained. The impact on others is an index value that measures the number of users accessing the content. The impact on others can be calculated by referencing the access rights and access log of the content and calculating the ratio of the number of users who have previously accessed the content (hereinafter referred to as the "number of accessors") to the number of users who can access the content (hereinafter referred to as the "number of accessors"). It is believed that the more users access a piece of content, the greater the impact of deleting it. Therefore, the greater the value of the impact on others, the greater the impact of deleting the content. In other words, as the ratio of the number of accessors to the number of accessible users increases, the value of the impact on others of the accessed content increases. Conversely, as the ratio of the number of accessors to the number of accessible users decreases, the value of the impact on others of the accessed content decreases.

[0014] However, your own access information is not required to calculate the value of the impact on others. Therefore, if you yourself are included in either the number of people who can access the content or the number of people who have accessed it, 1 is subtracted from that number. This allows, for example, the value of the impact on others of content that only you have accessed to be calculated as 0. As a result, the value of the impact on others can be calculated accurately.

[0015] For individuals, the number of permitted accesses is calculated based on the number of users with access rights read from access right information indicating access rights to content. For groups, the number of permitted accesses is calculated by accessing the directory server from the group information, extracting user information from the directory server's member information, and then reading the user information to calculate the number of users with access rights. However, the number of users included in the number of permitted accesses is only the number of users who have accessed the file server at least once in the past (hereinafter referred to as the "number of active users"); other users are not included in the number of permitted accesses.

[0016] For example, if the total number of employees includes a group with only a small number of members accessing the file server or a group with a large number of inactive users, the impact on others will be low regardless of the actual usage status of the content. However, by using only the number of active users as the number of users who can access the file server, it is possible to calculate the impact on others more accurately.

[0017] (Impact on immediate business) Next, we will explain the impact on recent business operations. The more frequently accessed content is recently, the more likely it is that it is being used in recent business operations, and so deleting that content is likely to have a large impact. Therefore, the value of the impact on recent business operations is calculated taking into account the chronological order of the content's access logs.

[0018] The recentness of an access can be quantified based on the access log collection period (number of days) and the appearance date of any access log for the target content (i.e., the number of days since collection began). Therefore, the recentness of all access logs for the target content is quantified, and the average value is used as the impact on recent business operations. The higher the impact on recent business operations, the more recently accesses have been concentrated, and the greater the impact of deleting the content.

[0019] (Impact on business) Next, the impact on work will be explained. The impact on others is used as a basic score to measure the degree of influence on others. The impact on the most recent work is used as a weight by which the basic score is multiplied. The impact on work is calculated by multiplying the basic score by the weight (i.e., multiplying the impact on others by the impact on the most recent work).

[0020] (Processing system configuration) 1 is a diagram illustrating an example of the configuration of a processing system 1 according to some embodiments of the present disclosure. As shown in FIG. 1, the processing system 1 includes a target file server 10, a client 20, a deletion permission determination server 30, and a directory server 40.

[0021] The target file server 10 stores a group of files and folders that are the targets of content deletion determination.

[0022] The client 20 is a user's computer (for example, a personal computer terminal) that accesses the target file server 10. The client 20 detects an operation to delete content from the target file server 10. The client 20 also requests the deletion permission determination server 30 to determine whether the content can be deleted. Depending on the response from the deletion permission determination server 30, the client 20 permits, warns, or denies the deletion, and displays the result on an external display device. The client 20 is able to perform various processes by installing client software.

[0023] The deletion permission determination server 30 is a device that calculates the degree of impact on business operations and determines whether content can be deleted based on the calculated degree of impact on business operations. As shown in FIG. 1, the deletion permission determination server 30 includes an access log acquisition unit 301, a database 302, a file information acquisition unit 303, and an impact calculation unit 304.

[0024] The access log acquisition unit 301 periodically collects access logs from the target file server 10. The access log acquisition unit 301 then stores the collected access logs in the database 302. The database 302 stores the access logs. The file information acquisition unit 303 acquires access right information for the target content.

[0025] The impact calculation unit 304 receives information on the target content and the operating user from the client 20. The impact calculation unit 304 also receives access right information from the file information acquisition unit 303. Then, the impact calculation unit 304 uses the received information on the target content and the operating user, and the access right information to query the directory server 40 and calculate the number of people who can access it.

[0026] Furthermore, the impact calculation unit 304 acquires only the access logs of the target content from the access logs stored in the database 302. Then, the impact calculation unit 304 calculates the impact on business by multiplying the calculated number of accessible users (i.e., equivalent to the value of the impact on others) by the access log information (equivalent to the impact on the most recent business).

[0027] The directory server 40 stores information about users and groups for controlling access to the file server 10 .

[0028] The above-described processing performed by the processing system 1 according to the embodiment of the present disclosure is merely an example, and the processing system 1 is not limited to the above-described processing. For example, the processing system 1 may perform the processing described below.

[0029] (Processing performed by the processing system of the present disclosure) 2 is a diagram illustrating an example of a processing flow of the processing system 1 according to some embodiments of the present disclosure. Here, the processing performed by the processing system 1 illustrated in the processing flow of FIG. 2 will be described.

[0030] (Prerequisite processing) First, we will explain the processing that is a prerequisite for the processing performed by the processing system 1 shown in the processing flow of Fig. 2. The processing performed by the processing system 1 shown in the processing flow of Fig. 2 is premised on the fact that the deletion eligibility determination server 30 periodically operates the access log acquisition unit 301. Furthermore, the processing performed by the processing system 1 shown in the processing flow of Fig. 2 is premised on the fact that the deletion eligibility determination server 30 acquires information on the access log (reference and update) to the content from the target file server 10, and stores the acquired access log in the database 302.

[0031] 3 is a diagram illustrating an example of a database 302 according to some embodiments of the present disclosure. As illustrated in FIG. 3, the database 302 stores, for each ID, a user ID (identifier), an operation, a file path, and a time, in association with each other (i.e., the user corresponding to the user ID performed the operation indicated in the operation on the file indicated in the file path at the date and time indicated in the time).

[0032] 4 is a diagram illustrating an example of a process for acquiring access log information performed by the deletion eligibility determination server 30 according to some embodiments of the present disclosure. The deletion eligibility determination server 30 starts the process as a constantly repeated process (step S101). The deletion eligibility determination server 30 acquires access log information (step S102). The deletion eligibility determination server 30 stores the acquired access log information in the database 302 (step S103). The deletion eligibility determination server 30 ends the constantly repeated process (step S104).

[0033] 5 is a diagram illustrating an example of a data table TBL according to some embodiments of the present disclosure. The data table TBL stores user information from an access log in order to manage users who have accessed content on the file server 10 at least once in the past as active users. As shown in FIG. 5, the data table TBL stores user names indicating active users for each user ID.

[0034] The impact calculation unit 304 of the deletion permission determination server 30 receives a request for determining whether deletion is possible from the client 20. The impact calculation unit 304 acquires the file or folder path to be deleted and the operating user information. Using the file or folder path information to be deleted, the impact calculation unit 304 acquires access right information with read permission for the target file via the file information acquisition unit 303. Note that if there are multiple files to be deleted, the impact calculation unit 304 performs this operation on all of them. Furthermore, if the deletion target includes a folder, it executes a process to acquire access right information with read permission for all files under it.

[0035] Furthermore, the influence calculation unit 304 queries the directory server 40 using the access right information for group authority and acquires information on the members (users) who belong to the group. Then, the influence calculation unit 304 calculates the total number of users after eliminating overlaps with user authority and excluding users other than active users as the number of people who can access the file.

[0036] Furthermore, the impact calculation unit 304 acquires the access logs of only the files to be deleted from the database 302. Then, the impact calculation unit 304 calculates the number of accessors from the acquired access logs. The impact calculation unit 304 calculates the ratio of the number of accessors to the number of accessible users as the impact on others (i.e., the basic score) as shown in formula (1).

[0037]

number

[0038] At this time, if the operating user himself / herself is included in either the number of accessors or the number of permitted accessors, the influence calculation unit 304 subtracts 1 from that number of accessors or the number of permitted accessors and then calculates the influence on others. However, to avoid division by 0, which would result in a denominator of 0 in equation (1), the denominator is exceptionally set to 1 only when the denominator becomes 0, and the influence on others is calculated.

[0039] Furthermore, based on the access logs, if the total number of access logs for the target file is n, the number of days for the collection period for all access logs is a, and the date on which the access log for the target file appeared (x days ago from the present), the impact calculation unit 304 calculates the impact (i.e., weight) on the most recent business using formula (2).

[0040]

number

[0041] The impact calculation unit 304 calculates the impact of deleting content on the business by multiplying the impact on others calculated for each target file by the impact on the most recent business, as shown in equation (3).

[0042]

number

[0043] 6 is a diagram illustrating an example of a process for calculating the impact on business operations performed by the impact calculation unit 304 according to some embodiments of the present disclosure. The impact calculation unit 304 acquires the access rights of the target file (step S201). The impact calculation unit 304 calculates the number of accessible users from the acquired access rights and the directory server 40 (step S202). The impact calculation unit 304 acquires the access log of the target file from the database 302 (step S203). The impact calculation unit 304 calculates the impact on business operations (step S204). Note that when there are multiple files to be deleted (including when the deletion target is a folder), the impact calculation unit 304 calculates the impact on business operations for all of the multiple files. The above is the prerequisite process for the process performed by the processing system 1 shown in the processing flow of FIG. 2.

[0044] Next, based on the above-mentioned premise process, the process performed by the processing system 1 shown in the process flow of Fig. 2 will be described. The client 20 enters a state in which it is ready to accept an operation by the user to delete any content in the target file server 10 (step S1). When the user performs an operation on the client 20 to delete any content in the target file server 10, the client 20 transmits a request to the deletion permission determination server 30 to determine whether the deletion is possible in response to the operation (i.e., requests the deletion permission determination server 30 to determine whether the deletion is possible) (step S2). At this time, the client 20 displays on the display device that it is in a standby state for deletion.

[0045] The deletion permission determination server 30 calculates a value of the degree of impact on business when it receives a request for determining whether deletion is possible from the client 20. Based on a preset threshold and the value of the degree of impact on business, the deletion permission determination server 30 notifies the client 20 of a response indicating whether the content can be deleted, indicating whether the content cannot be deleted, or a warning.

[0046] For example, the deletion permission determination server 30 determines whether the value of the impact on business is 0, greater than 0 and less than a threshold, or greater than or equal to a threshold (step S3). If the deletion permission determination server 30 determines that the value of the impact on business is 0, it notifies the client 20 that the deletion is permitted. If the deletion permission determination server 30 determines that the value of the impact on business is greater than 0 and less than the threshold, it notifies the client 20 that the deletion is not permitted. If the deletion permission determination server 30 determines that the value of the impact on business is greater than or equal to the threshold, it notifies the client 20 that the deletion is not permitted. Note that if there are multiple target files (including when the target is a folder), the deletion permission determination server 30 may determine whether the deletion is permitted based on the value of the file with the highest impact on business among the multiple files.

[0047] If the deletion permission determination server 30 determines that the value of the impact on business is 0 ("0" in step S3), it notifies the client 20 that the deletion is permitted (step S4). In response to the response (i.e., notification) from the deletion permission determination server 30, the client 20 permits the deletion and displays it on an external display device. Then, the client 20 executes a process to delete the content that was in a standby state (step S5). When the deletion of the content is complete, the client 20 displays on the display device that the deletion of the content has been completed. The client 20 ends the process.

[0048] Furthermore, if the deletion permission determination server 30 determines that the value of the impact on business is equal to or greater than the threshold value ("above threshold value" in step S3), it notifies the client 20 that deletion is not permitted (step S6). In response to the response (i.e., notification) from the deletion permission determination server 30, the client 20 denies the deletion and displays it on an external display device. Then, the client 20 suspends the process of deleting the content that has been put into a standby state (step S7). The client 20 ends the process.

[0049] Furthermore, if the deletion permission determination server 30 determines that the value of the impact on business is greater than 0 and less than the threshold value ("greater than 0 and less than the threshold value" in step S3), it notifies a warning to the client 20 (step S8). The client 20 then determines whether or not to delete the content (step S9). If the client 20 determines that the content should be deleted (YES in step S9), it proceeds to the processing of step S5. If the client 20 determines that the content should not be deleted (NO in step S9), it proceeds to the processing of step S7.

[0050] (advantage) The processing system 1 according to an embodiment of the present disclosure has been described above. In the processing system 1, the influence calculation unit 304 (an example of a first calculation unit) calculates the ratio of the number of accessors, which is the number of users who actually accessed the content, to the number of accessible users, which is the number of users who can access the content, as the influence on others. The influence calculation unit 304 (an example of a determination unit) makes a determination regarding the deletion of the content based on the influence on others. This processing system 1 can prevent content from being deleted due to an erroneous operation.

[0052] The first calculation unit 401 calculates the ratio of the number of users who actually accessed the content to the number of users who can access the content, as the degree of influence on others. The determination unit 402 determines whether to delete the content based on the degree of influence on others.

[0053] The first calculation unit 401 can be realized, for example, by using the function of the influence calculation unit 304 illustrated in Fig. 1. The determination unit 402 can be realized, for example, by using the function of the influence calculation unit 304 illustrated in Fig. 1.
