Description

The present invention relates to an information processing device, an information processing method, and a program.

A mobile terminal that stores data may be lost or stolen and acquired by another user. Then, there is a risk that the data in the mobile terminal may be viewed by the user who acquired the data. If the acquired user succeeds in user authentication, the mobile terminal may accept operations such as viewing and editing data.

As a technique related to user authentication, for example, an authentication device has been proposed that authenticates a person to be authenticated based on identification information inputted by the person to be authenticated into an information acquisition unit and authentication sequence information. In addition, for example, even if the user does not notice that the portable data recording terminal is lost or stolen, the portable data recording terminal can voluntarily and autonomously determine whether there is an abnormality such as loss or theft and prevent unauthorized access from unauthorized persons. Portable data recording terminals that can protect data have been proposed. Furthermore, for example, a photographing device has been proposed in which it is possible to easily authenticate reproducible image data through authentication.

However, when the acquirer of the mobile terminal is requested to perform user authentication for data manipulation using the mobile terminal, it is conceivable that the acquirer of the mobile terminal may try a method of retrieving data other than the data manipulation using the mobile terminal. As a result, data may be leaked from the mobile device.

In one aspect, this case aims to prevent data leakage.

One proposal provides an information processing device that includes a camera, a storage unit, and a processing unit. The camera can photograph the operator. The storage unit stores a plurality of files and person images. When the processing unit receives a first operation that is a predetermined input operation, the processing unit causes the camera to take an image of the operator, and if the first person appearing in the operator image and the second person appearing in the person image match, Allow acceptance of a second operation that includes operations on multiple files, and if the first person and second person do not match, delete the first file among the multiple files before accepting the second operation. Permit and update the person image to the operator image.

According to one aspect, data leakage can be prevented.

The present embodiment will be described below with reference to the drawings. Note that each embodiment can be implemented by combining a plurality of embodiments within a consistent range.
[First embodiment]
First, a first embodiment will be described.

FIG. 1 is a diagram illustrating an example of an information processing apparatus according to a first embodiment. The information processing device of the first embodiment determines whether or not stored data is to be deleted based on an image of the operator 1. The information processing device 10 is a portable electronic device. For example, the information processing device 10 is a mobile phone, a smartphone, a tablet terminal, a PDA (Personal Data Associate), a notebook PC (Personal Computer), or the like. The information processing device 10 may be connectable to a network or may not be connectable to a network.

The information processing device 10 includes a camera 11, a storage section 12, and a processing section 13. The camera 11 is capable of photographing the operator 1. For example, the camera 11 is installed to be able to photograph the front of the display screen of the information processing device 10. The storage unit 12 stores data used for processing executed by the information processing device 10. The storage unit 12 is, for example, a memory or a storage device included in the information processing device 10. The storage unit 12 stores files 12a-1, 12a-2, . . . and a person image 12b. The files 12a-1, 12a-2, . . . are at least some of the files stored in the information processing device 10. For example, the files 12a-1, 12a-2, . . . are each set to have a level of importance of "low," "medium," or "high." The person image 12b is an image of a person.

The processing unit 13 can control the information processing device 10 and execute required processing. The processing unit 13 is, for example, a processor or an arithmetic circuit included in the information processing device 10. The processing unit 13 causes the camera 11 to capture the operator image 2 when receiving a first operation that is a predetermined input operation. The first operation is, for example, pressing a predetermined key or touching a touch panel.

Next, the processing unit 13 compares the operator image 2 and the person image 12b. The processing unit 13 determines whether the first person shown in the operator image 2 and the second person shown in the person image 12b match. If the first person and the second person do not match, the processing unit 13 deletes the first file among the files 12a-1, 12a-2, . . . . Permits acceptance of second operations including operations to .... The second operation includes, for example, viewing, editing, and deleting the files 12a-1, 12a-2, . . . and instructing the execution of an application program installed in the information processing device 10.

Here, the processing unit 13 determines the first file according to the importance of each of the files 12a-1, 12a-2, . Furthermore, the processing unit 13 detects a first mark worn by the first person from the operator image 2, and detects a second mark worn by the second person from the person image 12b. The first mark and the second mark may be a mark such as a logo attached to clothing, or may be a hat or the like. Then, the processing unit 13 determines the first file depending on whether the first mark and the second mark match.

As an example, if the first person and the second person do not match and the first mark and the second mark match, the processing unit 13 selects an important one among the files 12a-1, 12a-2, . Delete files whose importance level is set to "medium" and files whose importance level is set to "high." Further, if the first person and the second person do not match, and the first mark and the second mark do not match, the processing unit 13 separates the file whose importance is set to "low" and the file whose importance is set to "medium". Delete files whose importance level is set to ``high'' and files whose importance level is set to ``high''.

Furthermore, if the first person and the second person match, the processing unit 13 allows acceptance of the second operation. However, the processing unit 13 deletes the second file among the files 12a-1, 12a-2, . . . depending on whether the poses of the first person and the second person match. As an example, the processing unit 13 detects the first pose of the first person from the operator image 2, and detects the second pose of the second person from the person image 12b. Then, if the first person and the second person match, but the first pose and the second pose do not match, the processing unit 13 deletes the file whose importance level is set to "high".

Then, the processing unit 13 updates the person image 12b to the operator image 2. That is, the processing unit 13 uses the operator image 2 in the current process as a comparison target as the person image 12b in the next process.

According to the first embodiment, when the processing unit 13 of the information processing device 10 receives a first operation that is a predetermined input operation, the processing unit 13 photographs the operator image 2 using the camera 11 that can photograph the operator. let When the first person appearing in the operator image 2 and the second person appearing in the person image 12b stored in the storage unit 12 match, the processing unit 13 updates the files 12a-1, 12a-2, . . . Allows the reception of the second operation including the operation. Further, if the first person and the second person do not match, the processing unit 13 deletes the first file among the files 12a-1, 12a-2, . . . and then permits reception of the second operation. do. Then, the processing unit 13 updates the person image 12b to the operator image 2. Thereby, the information processing device 10 can delete the file before the file is manipulated by the unauthorized operator 1. Therefore, the information processing device 10 can prevent data leakage.

Furthermore, the processing unit 13 determines the first file according to the importance of each of the files 12a-1, 12a-2, . Thereby, the information processing device 10 can preferentially delete files that are undesirable to be operated by an unauthorized operator 1.

Furthermore, the processing unit 13 detects the first pose of the first person from the operator image 2, and detects the second pose of the second person from the person image 12b. Then, if the first person and the second person match, but the first pose and the second pose do not match, the processing unit 13 selects the second file among the files 12a-1, 12a-2, . delete. Thereby, the information processing device 10 can further improve security.

Furthermore, the processing unit 13 detects a first mark worn by the first person from the operator image 2, and detects a second mark worn by the second person from the person image 12b. Then, the processing unit 13 determines the first file depending on whether the first mark and the second mark match. As a result, the information processing device 10 can delete the file to be deleted depending on whether the operator 1 belongs to the same organization as the person appearing in the person image 12b or when the operator 1 has acquired the information processing device 10 illegally. It can be changed.

Note that the second operation may include a login operation, and the processing unit 13 allows reception of operations on the files 12a-1, 12a-2, . . . when the login operation is successful. Good too. Thereby, the information processing device 10 can prevent file operations by the unauthorized operator 1.

[Second embodiment]
Next, a second embodiment will be described. In the second embodiment, a plurality of information processing apparatuses are jointly used by a plurality of users.

FIG. 2 is a diagram showing an overview of the second embodiment. In the second embodiment, users 20-1, 20-2, . . . jointly use information processing apparatuses 100-1, 100-2, . The users 20-1, 20-2, . . . belong to the same organization (for example, the same business office of the same company). The users 20-1, 20-2, . . . wear the same mark (for example, a logo on clothing) from the start to the end of the workday. When the user 20-1 starts work, he selects one of the information processing devices 100-1, 100-2, . . . . The user 20-1 then uses the selected information processing device (for example, the information processing device 100-1) until the end of the day. For example, the user 20-1 may store files to be used in the information processing device 100-1 and carry them around. Similarly, the users 20-2, . . . use the information processing device selected from among the information processing devices 100-1, 100-2, .

Note that the user 20-1 may use another information processing device (for example, the information processing device 100-2) the next day. In other words, the information processing device 100-1 may be used by another user (for example, the user 20-2) the next day.

The information processing devices 100-1, 100-2, . . . are portable terminals managed by organizations to which the users 20-1, 20-2, . The information processing devices 100-1, 100-2, . . . are, for example, (stand-alone) tablet terminals, PDAs, etc. that do not have the function of connecting to a network. Further, it is assumed that the login password of the information processing apparatuses 100-1, 100-2, . . . is common and known by the users 20-1, 20-2, .

The information processing apparatuses 100-1, 100-2, . . . photograph the operator when they receive a key press or a touch operation after being activated. Then, the information processing devices 100-1, 100-2, . and application program execution instructions. In the following description, it is assumed that the information processing apparatus 100-1 captured an image of the user 20-1 when it was activated last time.

FIG. 3 is a diagram illustrating an example of the hardware configuration of the information processing device. The entire information processing device 100-1 is controlled by a processor 101. A memory 102 and a plurality of peripheral devices are connected to the processor 101 via a bus 108. Processor 101 may be a multiprocessor. The processor 101 is, for example, a CPU (Central Processing Unit), an MPU (Micro Processing Unit), or a DSP (Digital Signal Processor). At least a part of the functions realized by the processor 101 executing a program may be realized by an electronic circuit such as an ASIC (Application Specific Integrated Circuit) or a PLD (Programmable Logic Device).

Memory 102 is used as a main storage device of information processing device 100-1. The memory 102 temporarily stores at least a portion of OS (Operating System) programs and application programs to be executed by the processor 101. The memory 102 also stores various data used for processing by the processor 101. As the memory 102, a volatile semiconductor storage device such as a RAM (Random Access Memory) is used, for example.

Peripheral devices connected to the bus 108 include a storage device 103, a display device 104, a touch panel 105, a device connection interface 106, and a camera 107.

The storage device 103 electrically or magnetically writes and reads data to and from a built-in recording medium. The storage device 103 is used as an auxiliary storage device for the information processing device 100-1. The storage device 103 stores OS programs, application programs, and various data. Note that as the storage device 103, for example, an HDD (Hard Disk Drive) or an SSD (Solid State Drive) can be used.

Display device 104 displays images according to instructions from processor 101. Examples of the display device 104 include a display device using organic EL (Electro Luminescence), a liquid crystal display device, and the like. The touch panel 105 is arranged in front of the screen of the display device 104, detects a pressed position on the screen, and transmits a signal indicating the position to the processor 101.

The device connection interface 106 is a communication interface for connecting peripheral devices to the information processing device 100-1. For example, the memory card 21 can be connected to the device connection interface 106. The memory card 21 is a card-type recording medium equipped with a communication function with the device connection interface 106.

The camera 107 is a photographing device installed in the information processing device 100-1. The camera 107 generates still image or moving image data of a scene ahead of which the lens of the camera 107 is directed, and stores it in the memory 102 according to instructions from the processor 101 . For example, the camera 107 is installed so that its lens faces the front of the display device 104.

The information processing device 100-1 can realize the processing functions of the second embodiment with the hardware configuration described above. The information processing apparatuses 100-2, . . . and the information processing apparatus 10 shown in the first embodiment can also be realized by the same hardware as the information processing apparatus 100-1 shown in FIG. Further, the processor 101 is an example of the processing unit 13 shown in the first embodiment. Further, the memory 102 or the storage device 103 is an example of the storage unit 12 shown in the first embodiment. Note that in the second embodiment, the information processing apparatuses 100-1, 100-2, . . . do not have the function of connecting to a network, but may further have a network interface.

The information processing device 100-1 realizes the processing functions of the second embodiment by executing a program recorded on a computer-readable recording medium, for example. A program that describes the processing content to be executed by the information processing device 100-1 can be recorded on various recording media. For example, a program to be executed by the information processing device 100-1 can be stored in the storage device 103. The processor 101 loads at least part of the program in the storage device 103 into the memory 102 and executes the program. Further, a program to be executed by the information processing device 100-1 may be recorded on a portable recording medium such as the memory card 21. The program stored in the portable recording medium becomes executable after being installed in the storage device 103 under the control of the processor 101, for example. Furthermore, the processor 101 can also directly read and execute a program from a portable recording medium.

Next, the functions of the information processing device 100-1 will be explained in detail.
FIG. 4 is a block diagram showing a functional example of the information processing device. The information processing device 100-1 includes a storage unit 110, a deletion determination unit 120, and a file operation reception unit 130. The storage unit 110 is realized using a storage area of the memory 102 or the storage device 103. The deletion determination unit 120 and the file operation reception unit 130 are realized by the processor 101 executing a program stored in the memory 102.

The storage unit 110 stores a person image 111, importance information 112, and files 113-1, 113-2, . The person image 111 is an image taken of the operator (that is, the user 20-1) at the time of the previous startup. The importance information 112 indicates the importance of each of the files 113-1, 113-2, . The files 113-1, 113-2, . . . are at least some of the files stored in the information processing device 100-1. The files 113-1, 113-2, . . . are, for example, program files, setting files, data files, etc. The files 113-1, 113-2, . . . are set to have a level of importance of “low,” “medium,” or “high.”

The deletion determination unit 120 determines the deletion range of the files 113-1, 113-2, etc. according to the degree of matching between the person image 111 and the operator image taken of the operator, and deletes the determined deletion range. After deleting the file, the file operation reception unit 130 is permitted to accept the operation. First, when a predetermined input operation (for example, pressing a predetermined key or touching the touch panel 105) is received, the deletion determination unit 120 causes the camera 107 to take an image of the operator's face (operator image). .

Next, the deletion determination unit 120 identifies the person appearing in each of the person image 111 and the operator image. For example, the deletion determination unit 120 extracts facial feature amounts from each of the person image 111 and the operator image. Further, the deletion determination unit 120 detects poses from each of the person image 111 and the operator image. For example, the deletion determination unit 120 determines which pose the person in each of the person image 111 and the operator image is in, based on the correspondence between the pose and the image feature.

Then, the deletion determination unit 120 determines whether or not the pose and person match between the person image 111 and the operator image. For example, if the difference between the facial feature amount extracted from the person image 111 and the facial feature amount extracted from the operator image is less than or equal to a threshold, the deletion determination unit 120 determines whether the person image 111 and the operator image are It is determined that they match. For example, if the pose detected from the person image 111 and the pose detected from the operator image match, the deletion determination unit 120 determines that the poses of the person image 111 and the operator image match. If the deletion determination unit 120 determines that the pose and person match between the person image 111 and the operator image, the deletion determination unit 120 updates the person image 111 to the operator image and allows the file operation reception unit 130 to accept the operation.

Further, if the poses do not match but the people match, the deletion determining unit 120 deletes the file whose importance level is set to "high". For example, the deletion determination unit 120 refers to the importance information 112 and identifies files whose importance is set to "high." The deletion determination unit 120 deletes the identified file. Then, the deletion determination unit 120 updates the person image 111 to an operator image, and permits the file operation reception unit 130 to accept the operation.

Further, when determining that the person image 111 and the operator image do not match, the deletion determination unit 120 detects marks worn by the person from each of the person image 111 and the operator image. For example, the deletion determination unit 120 extracts graphic feature amounts from each of the person image 111 and the operator image. Further, for example, the deletion determination unit 120 extracts character strings from each of the person image 111 and the operator image by character string recognition.

Then, the deletion determination unit 120 determines whether or not the marks worn by the person match in the person image 111 and the operator image. For example, if the difference between the feature amount of the figure extracted from the person image 111 and the feature amount of the figure extracted from the operator image is equal to or less than a threshold value, the deletion determination unit 120 determines that the person image 111 and the operator image are It is determined that the marks worn by the person match. Further, for example, if the character string extracted from the person image 111 and the character string extracted from the operator image match, the deletion determination unit 120 determines whether the character string in the person image 111 and the operator image is worn by the person. It is determined that the marks in the list match.

If the deletion determination unit 120 determines that the marks worn by the person match in the person image 111 and the operator image, the deletion determination unit 120 deletes the file whose importance level is set to “medium” or “high”. . For example, the deletion determination unit 120 refers to the importance information 112 and identifies files whose importance is set to "medium" or "high." The deletion determination unit 120 deletes the identified file. Then, the deletion determination unit 120 updates the person image 111 to an operator image, and permits the file operation reception unit 130 to accept the operation.

Further, if the deletion determination unit 120 determines that the marks worn by the person do not match between the person image 111 and the operator image, the deletion determination unit 120 sets the importance level to “low,” “medium,” or “high.” Delete the files that are. In other words, the deletion determination unit 120 deletes the files 113-1, 113-2, . Then, the deletion determination unit 120 updates the person image 111 to an operator image, and permits the file operation reception unit 130 to accept the operation.

The file operation accepting unit 130 accepts a file operation after the file is deleted by the deletion determining unit 120. First, the file operation reception unit 130 determines whether the login was successful. For example, the file operation reception unit 130 causes the display device 104 to display a screen prompting the user to enter a password. Then, the file operation reception unit 130 determines that the login has been successful if the input password matches the preset password. The file operation accepting unit 130 accepts the file operation when it is determined that the login has been successful.

For example, the file operation reception unit 130 views, edits, and deletes files 113-1, 113-2, . . . in response to an input from an operator. Further, for example, the file operation reception unit 130 may view, edit, or edit files stored in the information processing device 100-1 other than the files 113-1, 113-2, . . . Delete. Further, for example, the file operation reception unit 130 receives an instruction to execute an application program installed in the information processing device 100-1, and executes the application program.

Note that the lines connecting each element shown in FIG. 4 show a part of the communication route, and communication routes other than the illustrated communication route can also be set. Next, the importance information stored in the information processing device 100-1 will be explained in detail.

FIG. 5 is a diagram illustrating an example of importance information. The importance information 112 indicates the importance of each of the files 113-1, 113-2, . . . . The importance information 112 has items of file name and importance. The file name of one of the files 113-1, 113-2, . . . is set in the file name field. For the importance level item, one of "low", "medium", and "high" is set.

Here, the files set as "high" in importance are particularly important data files among the data files used by the user 20-1, such as customer information, for example. Further, a file whose importance level is set to "medium" is, for example, a data file used by the user 20-1. Furthermore, files whose importance level is set to "low" are data files that may be shared among the users 20-1, 20-2, . . . , for example.

As an example, the importance information 112 includes a record in which "file A" is set in the file name field and "high" is set in the importance field. A record in which "File A" is set in the file name field and "High" is set in the importance field indicates that the file with the file name "File A" is set to have "high" importance.

Next, the procedure of device operation reception processing by the information processing device 100-1 will be explained.
FIG. 6 is a flowchart (Part 1) illustrating an example of the procedure of the device operation reception process. The process shown in FIG. 6 will be described below in accordance with step numbers.

[Step S101] The information processing device 100-1 starts up. For example, the information processing device 100-1 is started by pressing the power button. Note that starting up the information processing device 100-1 may include, for example, returning from a sleep state or a hibernation state.

[Step S102] The deletion determination unit 120 determines whether a predetermined input operation has been received. For example, when the deletion determination unit 120 receives a press of a predetermined key or a touch operation on the touch panel 105, the deletion determination unit 120 determines that a predetermined input operation has been received. When the deletion determination unit 120 determines that the predetermined input operation has been received, the deletion determination unit 120 advances the process to step S103. If the deletion determining unit 120 determines that the predetermined input operation has not been received, the process proceeds to step S102.

[Step S103] The deletion determination unit 120 determines whether the surroundings are bright. If the deletion determining unit 120 determines that the surroundings are bright, the process proceeds to step S104. If the deletion determining unit 120 determines that the surroundings are not bright, the process proceeds to step S102.

[Step S104] The deletion determination unit 120 causes the camera 107 to take an image of the operator's face (operator image).
[Step S105] The deletion determination unit 120 determines whether a face is included in the operator image. For example, if facial feature amounts are detected from the operator image photographed in step S104, the deletion determination unit 120 determines that a face is included in the operator image. When the deletion determination unit 120 determines that a face is included in the operator image, the deletion determination unit 120 advances the process to step S106. Further, when the deletion determining unit 120 determines that the operator image does not include a face, the process proceeds to step S102.

[Step S106] The deletion determination unit 120 identifies the person appearing in each of the person image 111 and the operator image. For example, the deletion determination unit 120 extracts facial features from each of the person image 111 and the operator image photographed in step S104.

[Step S107] The deletion determination unit 120 detects poses from each of the person image 111 and the operator image. For example, the deletion determination unit 120 determines which pose the person in each of the person image 111 and the operator image is in, based on the correspondence between the pose and the image feature.

[Step S108] The deletion determination unit 120 determines whether the pose and person of the person image 111 and the operator image match. For example, if the difference between the facial feature amount extracted from the person image 111 and the facial feature amount extracted from the operator image in step S106 is less than or equal to the threshold, the deletion determination unit 120 determines whether the person image 111 and the operator image are different from each other. It is determined that the person matches. For example, if the pose detected from the person image 111 and the pose detected from the operator image match in step S107, the deletion determination unit 120 determines that the poses of the person image 111 and the operator image match. do. When the deletion determination unit 120 determines that the pose and person match between the person image 111 and the operator image, the deletion determination unit 120 advances the process to step S115. If the deletion determining unit 120 determines that the pose or person does not match between the person image 111 and the operator image, the process proceeds to step S109.

FIG. 7 is a flowchart (part 2) illustrating an example of the procedure of the device operation reception process. The process shown in FIG. 7 will be described below in accordance with step numbers.
[Step S109] The deletion determination unit 120 determines whether or not the person image 111 and the operator image match. For example, if the difference between the facial feature amount extracted from the person image 111 and the facial feature amount extracted from the operator image in step S106 is less than or equal to the threshold, the deletion determination unit 120 determines whether the person image 111 and the operator image are different from each other. It is determined that the person matches. When the deletion determination unit 120 determines that the person image 111 and the operator image match, the deletion determination unit 120 advances the process to step S110. Further, if the deletion determination unit 120 determines that the person image 111 and the operator image do not match, the deletion determination unit 120 advances the process to step S111.

[Step S110] The deletion determination unit 120 deletes files whose importance level is set to "high." For example, the deletion determination unit 120 extracts records whose importance level item in the importance level information 112 is "high." The deletion determination unit 120 deletes, among the files 113-1, 113-2, . . . , the file with the file name set in the file name field of the extracted record. The process then proceeds to step S115.

[Step S111] The deletion determination unit 120 detects a mark worn by a person from each of the person image 111 and the operator image. For example, the deletion determination unit 120 extracts graphic feature amounts from each of the person image 111 and the operator image photographed in step S104. Further, for example, the deletion determination unit 120 extracts a character string from each of the person image 111 and the operator image photographed in step S104 by character string recognition.

[Step S112] The deletion determination unit 120 determines whether the marks worn by the person match in the person image 111 and the operator image. For example, if the difference between the feature amount of the figure extracted from the person image 111 and the feature amount of the figure extracted from the operator image in step S111 is less than or equal to the threshold value, the deletion determination unit 120 determines whether the person image 111 and the operator image are different from each other. It is determined that the marks worn by the person match. Further, for example, if the character string extracted from the person image 111 and the character string extracted from the operator image match, the deletion determination unit 120 determines whether the character string in the person image 111 and the operator image is worn by the person. It is determined that the marks in the list match. When the deletion determination unit 120 determines that the marks worn by the person match in the person image 111 and the operator image, the process proceeds to step S113. Further, if the deletion determination unit 120 determines that the marks worn by the person do not match between the person image 111 and the operator image, the deletion determination unit 120 advances the process to step S114.

[Step S113] The deletion determination unit 120 deletes files whose importance level is set to "medium" or "high." For example, the deletion determination unit 120 extracts records whose importance level item in the importance level information 112 is "medium" or "high." The deletion determination unit 120 deletes, among the files 113-1, 113-2, . . . , the file with the file name set in the file name field of the extracted record. The process then proceeds to step S115.

[Step S114] The deletion determination unit 120 deletes files whose importance level is set to "low," "medium," or "high." In other words, the deletion determination unit 120 deletes the files 113-1, 113-2, .

[Step S115] The deletion determination unit 120 updates the person image 111 to the operator image photographed in step S104.
[Step S116] The file operation reception unit 130 determines whether the login was successful. For example, the file operation reception unit 130 causes the display device 104 to display a screen prompting the user to enter a password. Then, the file operation reception unit 130 determines that the login has been successful if the input password matches the preset password. Furthermore, if the input password and the preset password do not match, the file operation reception unit 130 determines that the login has failed. If the file operation receiving unit 130 determines that the login is successful, the process proceeds to step S117. Further, if the file operation receiving unit 130 determines that the login has failed, the process proceeds to step S116.

[Step S117] The file operation accepting unit 130 accepts a file operation. For example, the file operation reception unit 130 views, edits, and deletes files 113-1, 113-2, . . . in response to an input from an operator. Further, for example, the file operation reception unit 130 may view, edit, or edit files stored in the information processing device 100-1 other than the files 113-1, 113-2, . . . Delete. Further, for example, the file operation reception unit 130 receives an instruction to execute an application program installed in the information processing device 100-1, and executes the application program.

[Step S118] The file operation reception unit 130 receives an instruction to stop the information processing device 100-1. Then, the file operation reception unit 130 stops the information processing device 100-1. Note that stopping the information processing device 100-1 may include, for example, transitioning to a sleep state or a hibernation state.

In this way, the information processing device 100-1 causes the camera 107 to take an image of the operator when receiving a predetermined input operation. If the pose and person of the operator image and the person image 111 match, and the login is successful, the information processing device 100-1 allows acceptance of the file operation. Thereby, the information processing apparatus 100-1 can permit the user 20-1 to operate the files without deleting the files 113-1, 113-2, .

Furthermore, if the person and the mark worn by the person do not match between the operator image and the person image 111, the information processing device 100-1 deletes the files 113-1, 113-2, etc. . Then, the information processing device 100-1 allows reception of file operations if the login is successful. As a result, if a predetermined input operation is performed by an unauthorized acquirer other than the users 20-1, 20-2, . ,... can be deleted. Therefore, the information processing device 100-1 can prevent data leakage. Furthermore, the information processing device 100-1 can prevent file operations by unauthorized acquirers by allowing acceptance of file operations when the login operation is successful.

Here, an unauthorized person may be able to obtain the password by spying on the login operation of the user 20-1. If the unauthorized acquirer successfully logs in, the information processing device 100-1 may store a new file created by the unauthorized acquirer. At this time, the information processing device 100-1 updates the person image 111 to an operator image in which the unauthorized acquirer is photographed. Then, the next time the unauthorized acquirer starts up the information processing device 100-1, the information processing device 100-1 does not delete the file created by the unauthorized acquirer. As a result, the unauthorized acquirer is unaware of the file deletion function of the information processing device 100-1. Therefore, the information processing device 100-1 can prevent an unauthorized acquirer from knowing that the user 20-1 has stored data in the information processing device 100-1.

Furthermore, if the operator image and the person image 111 match the person but do not match the pose, the information processing device 100-1 deletes the file whose importance level is set to "high". Thereby, the information processing apparatus 100-1 can further improve the security for files whose importance level is set to "high". Further, if the operator image and the person image 111 do not match the person but the mark worn by the person matches, the information processing device 100-1 sets the importance level to "medium" or "high". Delete the files. As a result, for example, if user 20-2 uses information processing device 100-1 on the day after user 20-1 uses information processing device 100-1, information processing device 100-1 is shared by the organization. You can leave the files in the file without deleting them.

As described above, the information processing device 100-1 determines the files to be deleted according to the importance of each file 113-1, 113-2, . You can preferentially delete files that are undesirable.

Although the embodiments have been illustrated above, the configuration of each part shown in the embodiments can be replaced with other components having similar functions. Further, other arbitrary components or steps may be added. Furthermore, any two or more configurations (features) of the embodiments described above may be combined.
