Description

The present invention relates to an information processing apparatus and the like.

Various data are stored in the system of a company or the like, and the user accesses the data stored in the system for various business purposes to check and update the data. In addition, the user creates and adds new data to the system as needed.

Here, since the amount of data that can be stored in the system is limited, the conventional system automatically deletes the data that has passed a certain period from the update date and time based on the update date and time of the data. ..

In addition, with the technology that automatically deletes data as described above, data that has passed a certain period of time from the update date and time is deleted uniformly, so when the user confirms each data saved in the system, a new one is newly deleted. When data is created, data that seems to be important is excluded from the deletion target, and measures are taken to prevent such data from being deleted.

In addition to the above measures, users also take data security measures and the like. For example, when checking each data stored in the system or when creating new data, the user can set a password etc. for the data that seems to be highly confidential to a third party. It suppresses browsing from and prevents information leakage.

However, the above-mentioned conventional technique has a problem that an appropriate value cannot be given to the data stored in the system.

For example, data stored in the system that is excluded from deletion or highly confidential data can be said to be high-value data, but the value of such data is not constant and fluctuates over time. be. That is, what was not valuable at the beginning of storage may increase in value due to changes in the internal environment or the like.

On the other hand, when the data is created, it is judged to be of high value, and the data excluded from the deletion target may lose its value thereafter. In such cases, data that is not worth storing will not be deleted indefinitely and will remain on the system.

Here, it is conceivable that the user periodically checks the data stored in the system one by one, reconsiders the value of the data, deletes it, and updates the password setting, but the amount of data is large. It is not realistic because it is huge.

In one aspect, it is an object of the present invention to provide an information processing device, a determination method and a determination program capable of imparting appropriate value to data.

In the first plan, the information processing apparatus has a storage unit, a specific unit, and an update unit. The storage unit stores the data in association with the value of the data. When the specific unit receives access to the data, the specific unit identifies the transfer information of the user who accessed the data. The update unit updates the value of the data based on the transfer information of the user specified by the specific unit.

Appropriate value can be added to the data stored in the system.

As shown in FIG. 3, the property information 141 has user identification information, a name, a retirement flag, transfer information, and a scheduled retirement date.

User identification information is information that uniquely identifies a user. The name indicates the name of the user. The transfer flag is a flag indicating whether the user corresponding to the user identification information is a mid-career retiree, a retired person, or a transfer person who is transferred from the current department to another department. For example, if the user is a mid-career retiree, a retired person, or a transferee, the transfer flag is set to "on". On the other hand, if the user does not fall under any of the mid-career retirees, retirees, and transfers, the transfer flag is set to "off".

The transfer information is information indicating whether the user corresponds to a mid-career retiree, a retired person, or a transfer person. If the user does not fall under any of the mid-career retirees, retirees, and transfers, the transfer information will be blank.

The scheduled retirement date indicates the scheduled retirement date of the user or the scheduled retirement date of the user. If the user does not fall under the category of mid-career retirees or retirees, the scheduled retirement date will be blank.

Returning to the description of FIG. The data table 142 is a table for storing data. FIG. 4 is a diagram showing an example of the data structure of the data table. As shown in FIG. 4, the data table 142 has data identification information, data, a deletion exclusion flag, and a protection target flag. Data identification information is information that uniquely identifies data. The data is the data to be saved.

The deletion exclusion flag is a flag indicating whether or not to exclude from the deletion target. When the deletion exclusion flag is "on", it indicates that the data is excluded from the deletion target. When the deletion exclusion flag is "off", it indicates that the data is not excluded from the deletion target. Data for which the deletion exclusion flag is "off" is deleted after a predetermined period has elapsed from the data access date and time.

The protection target flag is a flag indicating whether or not to take security measures for data. When the protection target flag is "on", it indicates that security measures are taken for the data. When the protection target flag is "off", it means that no security measures are taken for the data. For example, security measures include password setting and viewing restrictions.

Returning to the description of FIG. The value management table 143 is a table that holds information about the value given to the data. FIG. 5 is a diagram showing an example of the data structure of the value management table. As shown in FIG. 5, the value management table 143 has data identification information, data type, value, accessor identification information, access date and time, and comprehensive evaluation.

Data identification information is information that uniquely identifies data. The data type indicates the type of data. Value indicates the value given to the data. For example, the value includes a first value, a second value, and a third value.

The first value indicates the value regarding the confidentiality of data. The second value indicates the latest value of the data. The third value indicates the storage value of data.

The accessor identification information indicates the user identification information of the user who has accessed the corresponding data. The access date and time indicates the latest date and time when the corresponding data was accessed. Comprehensive evaluation indicates a comprehensive evaluation of the relevant data.

Returning to the description of FIG. The control unit 150 includes a reception unit 151, a specific unit 152, an update unit 153, and a post-processing unit 154. The control unit 150 is realized by a CPU (Central Processing Unit) or an MPU (Micro Processing Unit). Further, the control unit 150 may be executed by an integrated circuit such as an ASIC (Application Specific Integrated Circuit) or an FPGA (Field Programmable Gate Array).

The reception unit 151 executes the authentication process when the login request from the user terminal 10 is received. It is assumed that the login request includes the user identification information of the user who operates the user terminal 10. When the authentication is successful, the reception unit 151 allows the user terminal to access the data table 142. The authentication process executed by the reception unit 151 is a well-known authentication process using a password or the like.

When the authentication is successful, the user operates the user terminal 10 to confirm (view) and update the data registered in the data table 142. Further, the user may operate the user terminal 10 to add new data to the data table 142.

When the data registered in the data table 142 is confirmed and updated, the reception unit 151 updates the accessor identification information corresponding to the data identification information in the value management table 143 and the access date and time.

For example, when the reception unit 151 receives access to the data of the data identification information "Data-A" from the user terminal 10, the accessor identification information corresponding to the data identification information "Data-A", the access date and time. To update.

The accessor identification information is the user identification information included in the login request, and is the information that identifies the user who has accessed the data. The access date and time is the date and time when the access is received, and the reception unit 151 acquires it from the timer 135.

By the way, the user may operate the user terminal 10 to acquire the data in the data table 142 from the information processing apparatus 100 and perform various operations. For example, the user operates the user terminal 10 to print out data and save the data in an external storage device (write request). The reception unit 151 shall acquire information on the content of the operation for the data from the user terminal 10.

The reception unit 151 outputs the data identification information of the accessed data, the user identification information, and the information of the operation content executed for the data to the specific unit 152. The operation contents include confirmation, update, printout, storage in an external storage device, and the like.

The reception unit 151 receives a login request from the user terminal 10 and repeatedly executes the above process each time it receives various operations corresponding to the data.

The identification unit 152 determines whether or not the transfer flag corresponding to the user identification information is on based on the user identification information and the property information 141.

The processing of the specific unit 152 when the transfer flag is “on” will be described. The specifying unit 152 compares the user identification information with the property information 141, and identifies the transfer information corresponding to the user identification information. The identification unit 152 outputs the information in which the data identification information (data identification information of the accessed data), the transfer information, and the operation content are associated with each other to the update unit 153.

In the following description, the information in which the data identification information, the transfer information, and the operation content are associated with each other is referred to as "specific information". The transfer information included in the specific information is set to be a mid-career retiree, a retired person, or a transfer person.

The processing of the specific unit 152 when the transfer flag is “off” will be described. The specific unit 152 waits until the next user identification information and the operation content information are acquired from the reception unit 151.

The specific unit 152 repeatedly executes the above process each time it acquires data identification information, user identification information, and operation content information from the reception unit 151.

The update unit 153 is a processing unit that updates the value of data from the specific unit 152 based on specific information (transfer information, operation content). As described below, the update unit 153 executes the first update process and the second update process in order.

The "first update process" executed by the update unit 153 will be described. In the first update process, the update unit 153 updates the value of the data based on the transfer information and the operation content.

When the transfer information is "mid-career retired", the update unit 153 determines that "1" is added to the first value and the second value regardless of the operation content. The update unit 153 updates the value of the data in the value management table 143 by adding "1" to the first value and the second value corresponding to the data identification information included in the specific information.

When the transfer information is "retirement age" and the operation content is "confirmation", the update unit 153 determines that "1" is added to the third value. The update unit 153 updates the value of the data in the value management table 143 by adding "1" to the third value corresponding to the data identification information included in the specific information.

When the transfer information is "retirement age" and the operation content is "update", the update unit 153 determines that "2" is added to the third value. The update unit 153 updates the value of the data in the value management table 143 by adding "2" to the third value corresponding to the data identification information included in the specific information.

When the transfer information is "transferee" and the operation content is "update", the update unit 153 determines that "1" is added to the third value. The update unit 153 updates the value of the data in the value management table 143 by adding "1" to the third value corresponding to the data identification information included in the specific information.

The update unit 153 does not update the value of the data when the transfer information is "transferee" and the operation content is "confirmation".

The "second update process" executed by the update unit 153 will be described. The update unit 153 determines whether or not the operation content of the specific information includes a printout or storage of an external storage device. When the operation content includes printout or storage (write request) of the external storage device, the update unit 153 determines that "1" is added to the first value. The update unit 153 updates the value of the data in the value management table 143 by adding "1" to the first value corresponding to the data identification information included in the specific information.

In the above description, the update unit 153 has described the case where the information processing apparatus 100 executes the first update process and the second update process when the information processing apparatus 100 receives access to the data. However, the update unit 153 describes the case where the update unit 153 executes the first update process and the second update process. The next third update process may be executed each time.

The "third update process" executed by the update unit 153 will be described. The update unit 153 selects a record in the value management table 143 and identifies the accessor identification information included in the selected record. In the third update process, the record selected in the value management table 143 is referred to as a "selected record".

The update unit 153 compares the specified accessor identification information (user identification information) with the property information 141, and whether the retirement flag of the user identification information corresponding to the accessor identification information is "on". Judge whether or not.

The processing of the update unit 153 when the retirement flag is "on" will be described. The update unit 153 compares the accessor identification information with the property information 141, and identifies the transfer information and the scheduled retirement date of the user identification information corresponding to the accessor identification information.

When the transfer information is "mid-career retired", the update unit 153 determines that "1" is added to the first value. The update unit 153 updates the value of the data by adding "1" to the third value included in the selection record of the value management table 143.

When the transfer information is "retirement age", the update unit 153 specifies the access date and time included in the selection record of the value management table 143. The renewal unit 153 determines that "1" is added to the third value when the access date and time are included within the predetermined period starting from the scheduled retirement date. The update unit 153 updates the value of the data by adding "1" to the third value included in the selection record of the value management table 143.

The update unit 153 updates the value of the data by repeatedly executing the above process while switching the selected record in the value management table 143 at predetermined intervals.

Returning to the description of FIG. The post-processing unit 154 executes various post-processing based on the value corresponding to the data recorded in the value management table 143. For example, the post-processing unit 154 executes the first post-processing, the second post-processing, the third post-processing, the fourth post-processing, and the fifth post-processing.

The "first post-processing" executed by the post-processing unit 154 will be described. The post-processing unit 154 performs comprehensive evaluation for each data identification information by executing the following processing, and registers the evaluation result in the value management table 143.

For example, the post-processing unit 154 calculates an evaluation value based on the equation (1). Α, β, and γ in the equation (1) are preset coefficients. When the evaluation value is equal to or more than the threshold value Th1 and less than the threshold value Th2, the post-processing unit 154 sets the comprehensive evaluation to “D”. When the evaluation value is the threshold value Th2 or more and less than the threshold value Th3, the post-processing unit 154 sets the comprehensive evaluation as “C”. When the evaluation value is the threshold value Th3 or more and less than the threshold value Th4, the post-processing unit 154 sets the comprehensive evaluation as “B”. When the evaluation value is the threshold value Th4 or more, the post-processing unit 154 sets the overall evaluation as “A”.

Evaluation value = α x 1st value + β x 2nd value + γ x 3rd value ... (1)

The "second post-processing" executed by the post-processing unit 154 will be described. The post-processing unit 154 selects a record in the value management table 143, and determines whether or not the first value included in the selected record (selected record) is equal to or greater than the threshold value Th. When the first value included in the selected record is equal to or greater than the threshold value Th, the post-processing unit 154 specifies the data identification information of the selected record. The post-processing unit 154 sets the protection target flag of the data table 142 corresponding to the specified data identification information to “on”.

The "third post-processing" executed by the post-processing unit 154 will be described. The post-processing unit 154 selects a record in the value management table 143, and determines whether or not the third value included in the selected record (selected record) is equal to or higher than the threshold value Thb. When the third value included in the selected record is equal to or greater than the threshold value Thb, the post-processing unit 154 identifies the data identification information of the selected record. The post-processing unit 154 sets the deletion exclusion flag of the data table 142 corresponding to the specified data identification information to “on”.

The "fourth post-processing" executed by the post-processing unit 154 will be described. The post-processing unit 154 scans the access date and time of the value management table 143 and identifies the data identification information for which a predetermined period has elapsed from the current date and time. The post-processing unit 154 refers to the data table 142, and deletes the data corresponding to the specified data identification information when the deletion exclusion flag corresponding to the specified data identification information is “off”.

The "fifth post-processing" executed by the post-processing unit 154 will be described. The post-processing unit 154 refers to the data table 142, and if there is a record whose protection target flag is “on”, the post-processing unit 154 sets a password for the data of the record whose protection target flag is “on”. For example, the post-processing unit 154 sets a randomly generated password, and notifies the terminal device of the administrator of the set password and the data identification information.

Next, an example of the processing procedure of the information processing apparatus 100 according to this embodiment will be described. FIG. 6 is a flowchart showing a processing procedure of the information processing apparatus according to the present embodiment. As shown in FIG. 6, the reception unit 151 of the information processing apparatus 100 receives a login request from the user terminal 10 (step S101). The reception unit 151 specifies the data identification information and the operation content of the data accessed by the user (step S102).

The identification unit 152 of the information processing apparatus 100 determines whether or not the retirement flag corresponding to the user identification information included in the login request is on (step S103). If the retirement flag is not turned on (step S103, No), the specific unit 152 ends the process.

On the other hand, when the retirement flag is on (step S103, Yes), the specifying unit 152 identifies the transfer information of the user (step S104).

The update unit 153 of the information processing apparatus 100 executes the update process (step S105). The update unit 153 determines whether or not the operation content includes a write request (step S106). When the write request is included (step S106, Yes), the update unit 153 adds 1 to the first evaluation for the data identification information (step S107).

On the other hand, if the write request is not included (step S106, No), the update unit 153 ends the process.

Next, an example of the update process shown in step S105 of FIG. 6 will be described. FIG. 7 is a flowchart showing a processing procedure of the update process. As shown in FIG. 7, when the transfer information is a transfer person (steps S201, Yes), the update unit 153 of the information processing apparatus 100 determines whether or not the operation content is an update (step S202). ).

When the operation content is update (step S202, Yes), the update unit 153 adds 1 to the third value (step S203). On the other hand, if the operation content is not an update (step S202, No), the update unit 153 ends the update process.

On the other hand, when the transfer information is not a transfer person (step S201, No), the update unit 153 determines whether or not the transfer information is a mid-career retired person (step S204). When the transfer information is a mid-career retiree (step S204, Yes), the update unit 153 adds 1 to the first value and the second value (step S205).

On the other hand, if the transfer information is not a mid-career retiree (step S204, No), the update unit 153 determines whether or not the operation content is update (step S206). When the operation content is update (step S206, Yes), the update unit 153 adds 2 to the third value (step S207).

On the other hand, when the operation content is not an update (step S206, No), the update unit 153 adds 1 to the third value (step S208).

The process described with reference to FIG. 7 is a processing procedure corresponding to the “first update process” of the update unit 153, and the process shown in steps S106 and 107 of FIG. 6 is the “second update process” of the update unit 153. It is a processing procedure corresponding to.

Next, an example of the processing procedure of the third update process executed by the update unit 153 will be described. FIG. 8 is a flowchart showing a processing procedure of the third update process. As shown in FIG. 8, the update unit 153 of the information processing apparatus 100 selects a record in the value management table 143 and identifies the accessor identification information (step S301).

The update unit 153 determines whether or not the retirement flag corresponding to the accessor identification information is turned on based on the property information 141 (step S302). If the retirement flag is not turned on (step S302, No), the update unit 153 ends the process.

On the other hand, when the retirement flag is turned on (step S302, Yes), the update unit 153 determines whether or not the transfer information corresponding to the accessor identification information is a transfer person (step S303). .. If the transfer information is a transfer person (step S303, Yes), the update unit 153 ends the process.

On the other hand, when the transfer information is not a transfer person (step S303, No), the update unit 153 determines whether or not the transfer information is a mid-career retired person (step S304). When the transfer information is a mid-career retiree (step S304, Yes), the update unit 153 adds 1 to the first evaluation value (step S305).

On the other hand, if the transfer information is not a mid-career employee (step S304, No), the update unit 153 specifies the access date and time (step S306). The renewal unit 153 determines whether or not the access date and time is included within a predetermined period starting from the scheduled retirement date (step S307). If the access date and time is not included within a predetermined period starting from the scheduled retirement date (step S307, No), the update unit 153 ends the process.

On the other hand, if the access date and time is included within a predetermined period starting from the scheduled retirement date (step S307, Yes), the renewal unit 153 adds 1 to the third value (step S308).

Next, the effect of the information processing apparatus according to this embodiment will be described. When the information processing apparatus 100 receives access to the data, the information processing apparatus 100 identifies the transfer information of the user who has accessed the data, and updates the value of the data based on the transfer information. This makes it possible to add appropriate value to the data stored in the system.

The information processing apparatus 100 updates the value of data based on the transfer information of the accessing user and the operation content. As a result, even users of the same transfer information can add appropriate value to the data according to the operation content. For example, if the operation content is an update, it can be said that the data has more storage value than the confirmation data. Therefore, if the operation content is an update, it is more than the confirmation data. Give the data a large third value.

The information processing apparatus 100 sets the first value, the second value, and the third value as the values to be given to the data, and sets one of the values according to the transfer information of the accessing user and the operation content. Update. This makes it possible to add value to the data from various perspectives.

The information processing apparatus 100 adds a predetermined value to the first value and the second value when a mid-career retired person is set in the transfer information of the user who has accessed. Since the data accessed by the mid-career is highly confidential and the data itself is valuable, it is possible to give appropriate value to the data.

In the information processing apparatus 100, when the transfer information of the accessing user is a retired person and the operation content is updated, the transfer information of the accessing user is a retired person. A larger value than when the operation content is confirmation is added to the third value of the data. The data that the retired person accesses and updates may have the know-how etc. left by the retired person, so it can be said that the data has a higher preservation value. Can be granted.

In the information processing apparatus 100, when the transfer information of the accessing user is a retired person and the operation content is updated, the transfer information of the accessing user is a transfer person and , A larger value is added to the third value of the data than when the operation content is update. Since it can be said that the data accessed and updated by the retired person has a higher storage value than the data accessed and updated by the transferee, the data can be given an appropriate value by the above processing.

The information processing apparatus 100 sets the third value of the data when the transfer information of the user who accessed the data is a retired person and the date and time of access is included within a predetermined period starting from the scheduled retirement date. Add the specified value. The data that the retired person accesses and updates near the retirement date can be said to be data with higher preservation value because the retired person may have left know-how, etc., and by the above processing , Can add appropriate value to the data.

By the way, the process of the information processing apparatus 100 described in the above embodiment is an example, and other processes may be executed to add value to the data. For example, other additional information may be further added to the transfer information of the user, and the additional information may be further used to add value to the data. The additional information includes information such as job title and whether or not the employee is a dispatched employee. When a predetermined position is set in the additional information, the update unit 153 corrects the value by multiplying the value added to the data by a correction value (a value larger than 1), and the corrected value. May be added. Data accessed by a user in a given job title may be of greater value than data accessed by a general user.

In addition, when dispatched employees are set in the additional information, the value is corrected by multiplying the value added to the data by the correction value (value of 0 or more and less than 1), and the corrected value is obtained. You may add. Temporary employees often do not know much about their work, so the value added to the data is reduced.

Next, an example of a computer hardware configuration that realizes the same functions as the information processing apparatus 100 shown in the above embodiment will be described. FIG. 9 is a diagram showing an example of a hardware configuration of a computer that realizes the same functions as the information processing apparatus of the embodiment.

As shown in FIG. 9, the computer 200 has a CPU 201 that executes various arithmetic processes, an input device 202 that receives data input from a user, and a display 203. Further, the computer 200 has a communication device 204 for exchanging data with an external device or the like via a wired or wireless network, and an interface device 205.
