Description

TECHNICAL FIELD Embodiments of the present invention relate to an information processing apparatus and an information processing program.

In recent years, with the advocacy of telework and the diversification of work methods, the number of cases where work is performed using an information processing device outside a security area (for example, outside the office or at home) is increasing. In this case, it is not preferable from the viewpoint of security that the information displayed on the information processing device is peeped by a third party (including family members). Similarly, due to the spread of mobile devices such as smartphones and tablet devices, when a mobile device is peeked at by a third party, or when a mobile device is handed over to a third party after allowing the viewing of specific information. In some cases, even unintended information may be seen. Such an act is undesirable from the viewpoint of security and privacy protection. Therefore, for example, by adding various information about the photographer to the content, capturing the image of the viewer at the time of viewing, identifying the viewer, and defining the relationship between the photographer and the viewer in advance has been proposed.

JP 2014-192851 A

However, in the case of the conventional technology, it is necessary to individually set restrictions in advance for contents (information) that should not be seen by third parties. For this reason, for a huge amount of content (information), individual setting work is required, which may increase the work load, and there is a possibility that setting errors or forgetting to set may occur. However, there were problems such as the loss of privacy and the possibility of information leakage being unable to be fully eliminated.

Accordingly, one example of the problem to be solved by the present invention is to provide an information processing apparatus and an information processing program that can easily avoid information that is not intended for viewing from being peeped at by a third party without increasing work load. That's what it is.

Further, the display control unit, for example, controls the first network name to which the display information creation device is connected, which is added when the display information as the attribute information is created, and the name of the network to which the display device is currently connected. Based on the result of comparison with the second network name, it is determined whether or not to display the display information.

In addition, for example, the display control unit controls, as the attribute information, the first creation time added at the time of creation of the first display information displayed on the display device before the replacement of the person is detected. Based on the result of comparison between the position information and the second created position information added when creating the second display information that can be displayed on the display device after the replacement of the person is detected, Determines whether or not to display display information.

In addition, for example, the display control unit controls, as the attribute information, first time information added at the time of creation of the first display information displayed on the display device before the replacement of the person is detected. and display of the second display information based on the result of comparison with the second time information added when creating the second display information that can be displayed on the display device after the replacement of the person is detected. to decide whether or not to

Further, for example, after the replacement of the person is detected, the display control unit controls face image information of the detected person and face image information included in the person image as display information that can be displayed on the display device. Based on the result of comparison with the above, it is determined whether or not to display the person image.

Also, the person detection unit detects the replacement of the person based on a change in the face image information of the person facing the display area, for example.

Also, the display information includes, for example, an application whose execution state can be displayed on the display device.

An information processing program according to a second aspect of the present invention includes an acquisition process for acquiring display information that can be displayed in a display area of a display device and attribute information accompanying the display information, and displaying the display information in the display area. a person detection process for detecting a person facing the display area, and determining whether or not to display the display information based on the attribute information when a change of the person facing the display area is detected. and a display control process to be executed by the information processing apparatus.

According to the above aspect of the present invention, when the change of the person facing the display area of the display device is detected, it is determined whether or not to display based on the attribute information of the display information. , and it is possible to easily hide display information that is not viewed by a third party.

Illustrative embodiments of the invention are disclosed below. The configurations of the embodiments shown below and the actions, results, and effects brought about by the configurations are examples. The present invention can be realized by configurations other than those disclosed in the following embodiments, and at least one of various effects based on the basic configuration and derivative effects can be obtained. .

An information processing apparatus (for example, a personal computer, a tablet terminal, a smartphone, etc.) according to an embodiment detects a change of a person facing a display unit (display area) of a display device, based on attribute information of display information to be displayed. It determines whether or not to display the display information.

FIG. 1 is an exemplary and schematic block diagram showing the configuration of an information processing apparatus 10 according to an embodiment. FIG. 1 shows a smart phone as an example of the information processing device 10 .

The information processing device 10 includes, for example, a CPU (central processing unit, processing unit) 12, a RAM (random access memory) 14, a ROM (read only memory) 16, a storage section 18, a communication section 20, a front camera (in-camera). 22, an iris recognition device 24, a display device 26, a position detection unit 28, and the like.

The CPU 12 reads an information processing program installed and stored in a non-volatile storage device such as the ROM 16, and implements a module that executes various controls and arithmetic processing according to the program. The CPU 12 includes, for example, an acquisition unit 12a, a person detection unit 12b, and a display control unit 12c as modules for determining whether or not to display display information (created documents, photographs, etc.) according to the present embodiment. Note that the CPU 12 realizes modules that realize other functions of the information processing device 10 (smartphone), such as a telephone function, a photographing function, a search function, a document creation function, a game function, and the like. Description of modules other than the display information display enable/disable function will be omitted.

The acquisition unit 12a acquires display information (eg, created documents, photographs, etc.) that can be displayed on the display unit 26a (display area) of the display device 26, and attribute information accompanying the display information (eg, date and time of creation, place of creation, etc.). Location information, network name connected at the time of creation, etc.). Details of display information and attribute information will be described later.

When display information is displayed on the display section 26a (display area), the person detection section 12b detects a person facing the display area (looking into the display section 26a). For example, the front camera 22 arranged around the display unit 26a of the information processing device 10 acquires a person (image that can be regarded as a human being) looking into the display unit 26a, and provides the display control unit 12c with the image.

The display control unit 12c acquires information about the person detected by the person detection unit 12b, and detects whether or not there is a change in the person facing the display unit 26a. For example, an authorized user (for example, a person who has been authenticated by biometric (iris) authentication or the like) of the information processing apparatus 10 that was originally acquired may transfer image information to an unauthorized user (another person whose authentication has been rejected). When the display information is changed, whether or not to display the display information is determined based on the attribute information accompanying the display information. For example, processing that does not execute display itself, or processing that indicates the presence of display information but makes it unrecognizable by mask processing or the like is executed.

The RAM 14 is a volatile memory that temporarily stores (holds) various data used in calculations by the CPU 12, captured image data captured by the front camera 22, and the like.

The ROM 16 stores an information processing program 16a for realizing information processing (display image display enable/disable processing) by the CPU 12, as well as various programs for realizing the above-described telephone function, search function, and the like. The ROM 16 also stores parameters and the like necessary for executing various programs.

The storage unit 18 is a non-volatile, rewritable memory, and includes information (created document data) of a document created by the document creation function realized by the CPU 12, and an image captured by the front camera 22, the rear camera, etc. by the shooting function. Display information 18a such as captured photos and external information (document information data, photo data, etc.) acquired from an external server or another smartphone via the communication unit 20 can be sequentially saved and updated. Various applications 18b that can be executed by the CPU 12 are also stored. As described above, the information stored in the storage unit 18 (in particular, the display information 18a) basically includes the creation (acquisition) date and time, the location information of the creation (acquisition) place, the Attribute information such as the network name that has been displayed is linked and can be used when deciding whether to display it. The attribute information can be used not only for deciding whether to display the information, but also for managing the display information.

The communication unit 20 communicates with external communication devices according to various functions executed by the CPU 12 . For example, the communication unit 20 communicates with an external server via a network to obtain desired information (document data, image data, photo data, etc.). The communication unit 20 also transmits document data, image data, and photo data created by the information processing apparatus 10 to an external communication device (such as another smartphone) or an external server. When connecting to a network, the communication unit 20 acquires a network name (for example, an SSID (Service Set Identifier) of an access point (AP)) of a wireless LAN standard (WiFi (registered trademark): Wireless Fidelity). Then, the information processing device 10 attaches it to the acquired document data, image data, photo data, etc. Further, the information processing device 10 attaches the SSID acquired by the communication unit 20 to the document data created by the information processing device 10 and It can be attached to image data, photograph data, etc. as one of position information at the time of creation.

The front camera 22 is a camera mounted on a part (for example, the upper end) of the display device 26, is positioned on the side of the display section 26a, and is mainly used by a person facing the information processing apparatus 10 (the display section 26a). The person looking into the camera) is photographed. The front camera 22 is, for example, a digital camera incorporating an imaging device such as a CCD (Charge Coupled Device) or CIS (CMOS image sensor). The front camera 22 outputs moving image data (captured image data 30) at a predetermined frame rate, and sequentially provides it to the human detection unit 12b. Further, it is also possible to store captured image data 30 output from the front camera 22 in the storage unit 18 as still image data or moving image data using the camera function realized by the CPU 12 . Note that when the captured image data 30 is stored in the storage unit 18, as described above, the attribute information indicating the shooting position, the shooting date and time, and the like is linked and stored. Although not shown, the information processing apparatus 10 may include a main camera (a rear camera or the like in the case of a smartphone) in addition to the front camera 22. Similarly, still image data having attribute information, You may make it preserve|save moving image data in the memory|storage part 18. FIG.

Like the front camera 22, the iris recognition device 24 is, for example, a digital camera incorporating an imaging device such as a CCD or CIS, and outputs moving image data (captured image data, image information) at a predetermined frame rate. The iris recognition device 24 has a filter that cuts off the visible light range, and captures an image in the near-infrared range with a wavelength range of 780 nm to 2500 nm, for example. The iris recognition device 24 emits near-infrared light emitted by a near-infrared irradiation unit (not shown) to an object, in this case, a person holding the information processing device 10 (mainly a person looking into the display unit 26a, a display unit 26a, etc.). An image based on the near-infrared light reflected by the face of the person facing 26a is captured. The iris recognition device 24 captures an image only when performing iris recognition of the pupil E of a person mainly included in the image. Therefore, the near-infrared irradiation unit also irradiates near-infrared light at the timing when the iris recognition device 24 takes an image. The captured image data is subjected to authentication processing using a well-known technique. and,
A person looking into the information processing device 10 (a person holding the information processing device 10, a person facing the information processing device 10) is permitted to use the information processing device 10 (registered). A determination is made as to whether the user is authorized.

The display device 26 includes a display section 26a and a touch panel 26b. The display unit 26a is, for example, an LCD (liquid crystal display), an OELD (organic electroluminescent display), or the like. Further, the display section 26a is covered with a touch panel 26b as a transparent operation input section. An operator (user) visually recognizes information (for example, image data 32 as display information stored in the storage unit 18) displayed on the display area (display screen) of the display unit 26a via the touch panel 26b. be able to. Further, the operator touches, presses, or moves the touch panel 26b with a finger or the like at a position corresponding to the image (display information, image data 32) displayed in the display area of the display unit 26a, thereby performing an operation. Input can be performed.

The position detection unit 28 acquires, for example, a GPS (Global Positioning System) signal, and acquires position information (for example, latitude and longitude information) of the current position of the information processing device 10 . By acquiring the current position information of the information processing device 10 with the position detection unit 28, the acquisition position information of the captured image data captured using the camera function of the information processing device 10 and the document creation function of the information processing device 10 can be obtained. It is possible to acquire the creation position information of the created document data created using.

FIG. 2 shows a folder 32F storing display information that can be displayed on the information processing apparatus 10 and stored in the storage unit 18 . The folder 32F shows an example in which image data 32 (display information) such as still image data and moving image data captured by the front camera 22 or the main camera is stored.

In the case of FIG. 2, the folder 32F stores, for example, image data 32a to 32e (image data 32) as photographic data of still images. For example, the image data 32a is a close-up photograph of a person 34 wearing a T-shirt printed with a cat pattern (close-up photograph of a cat pattern). The image data 32b is a photograph with a different angle of view than the image data 32a, and is a photograph in which the face of the person 34 is included. The image data 32c is a snapshot of another person 36. FIG. The image data 32d is a snapshot of the cat 38, and the image data 32e is a photograph of the facial expression of the cat 38 taken at a timing different from that of the image data 32d.

Further, each image data 32 (32a to 32e) is accompanied by, for example, conditions at the time of photographing as attribute information 40. FIG. The attribute information 40 (40a to 40e) associated with each image data 32 (32a to 32e) includes, for example, position information (latitude and longitude information based on GPS signals) acquired by the position detection unit 28, time information , the date and time indicating the shooting date and shooting time are shown. As other positional information indicating the position where the information processing device 10 is used, SSID is attached to each image data 32 as attribute information 40 . The SSID is used when the information processing device 10 is connected to the network via the communication unit 20 at the location where the information processing device 10 is used, that is, the location where the image data 32 is acquired (captured). Indicates the location of a WiFi access point (AP). When the information processing apparatus 10 is used without being connected to the network, the SSID column is blank as shown in the attribute information 40c corresponding to the image data 32c.

In the example shown in FIG. 2, the latitude and longitude information of the attribute information 40 of the image data 32a, 32b, 32d, and 32e are substantially the same. Also, the SSIDs of the attribute information 40 of the image data 32a, 32b, 32d, and 32e are the same. Therefore, it can be estimated that the image data 32a, 32b, 32d, and 32e are photographs of the person 34, the cat 38 owned by the person 34, etc. taken at substantially the same position (for example, the person's 34 home). On the other hand, the image data 32c differs from the image data 32a, 32b, 32d, and 32e in latitude and longitude information, and the SSID is not recorded. That is, it can be estimated that the image data 32c are photographs taken at different locations (for example, travel destinations). Therefore, in the examples using FIGS. 3 and 4, which will be described later, an example in which the image data 32c is hidden when a change of persons is detected is shown. Note that FIG. 2 also shows the state of the display flag 42 when the display information (image data 32) display enable/disable process by the information processing apparatus 10 is executed. Details of the display flag 42 will be described later.

FIG. 3 shows display information display enable/disable processing executed using the information processing apparatus 10 configured as described above and the folder 32F (image data 32) and the attribute information 40 stored in the storage unit 18. Scenes 44a to 44e (scene 44) shown and a display example 50 shown in FIG. That is, when the change of the person facing the display unit 26a (display area) of the display device 26 of the information processing device 10 is detected, the display information (image data 32) is displayed based on the attribute information 40 of the display information (image data 32) An example of determining whether or not to display data 32) will be described.

In scenes 44a to 44e shown in FIG. 3, an authorized user of the information processing device 10 (for example, a person 46 who has completed iris (biometric) authentication) passes the information processing device 10 (for example, a smartphone) to a third party (person 34). 4 is an exemplary and schematic explanatory diagram showing a case where display information (image data 32) displayed on the information processing apparatus 10 is shown; FIG.

In a scene 44a, a person 46 authenticated as a registered authorized user of the information processing device 10 by iris authentication (biometric authentication) by the iris authentication device 24 of the information processing device 10 appears on the display unit of the information processing device 10. It is in a state of looking into 26a. Also, near the person 46 , there is a person 34 (non-registered person of the information processing apparatus 10 ) who is a third party and whose authentication is denied by biometric authentication by the iris recognition device 24 .

In the case of the scene 44a, since the person 46 looking into the display section 26a of the information processing device 10 has been affirmatively authenticated by the iris recognition device 24, as shown in the display example 50a of FIG. The stored display information (image data 32) can be browsed without any restrictions. In this case, for example, the image data 32a to 32e is displayed. At this time, the information processing apparatus 10 can browse all the image data 32 including the image data 32c of the travel destination that the person 46 does not want the person 34 to browse. In the display example 50a, for example, the image data 32c from among the thumbnails displayed in the thumbnail display area 52a is enlarged and displayed in the main display area 52b of the display section 26a.

Subsequently, in a scene 44b, a person 46 who is an authenticated and authorized user activates the information processing apparatus 10 to allow a person 34 who is an authenticated denyer to view the image data 32 stored in the storage unit 18. It is in a state of being handed over. A scene 44 c is a state in which the person 34 who received the information processing device 10 is looking into the display section 26 a of the information processing device 10 . In this case, as shown in a display example 50b of FIG. 4, a person 34 captured by the front camera 22 is displayed in the main display area 52b, and thumbnails of displayable image data 32 are displayed in the main display area 52b. there is In this case, the person 46 is out of the angle of view of the front camera 22 of the information processing device 10, and the person 34 is newly captured. That is, the person detection unit 12b detects that the person facing the display unit 26a (display area) has changed from the person 46 to the person 34. FIG. Then, the display control unit 12c refers to the attribute information 40 of each image data 32 and determines the image data 32 to be hidden.

For example, immediately before the person 46 who is an authentication affirmer hands over the information processing apparatus 10 to the person 34 who is an authentication denial, image data 32 other than the image data 32c that the person 34 does not want to see, for example, at the person 34's home Consider a case where the photographed image data 32a is displayed and only the photograph taken by the person 34 at home is viewed by the person 34. FIG. In this case, as described above, only the image data 32c is a photograph taken at a travel destination or the like, and the position information of the photographing place and the photographing date are greatly different. The attribute information 40 associated with the image data 32c does not include an SSID indicating connection to a network. Therefore, the display control unit 12c displays the thumbnails of the image data 32a, 32b, 32d, and 32e excluding the image data 32c as shown in a display example 50b, hides the image data 32c, and displays a blank image (B. I.) is displayed in the thumbnail display area 52a.

In the scene 44d, the person 46 receives the information processing device 10 and the iris recognition device 24 authenticates the image data 32c, which has been hidden, to the person 34 based on the permission of the person 46 with the pupil 46a. state. After the authentication is affirmed, the person 46 performs a predetermined operation to cancel the non-display processing of the image data 32c by the display control unit 12c. Here, the predetermined operation is, for example, a passcode input operation, a long press operation of the thumbnail image 32f, an operation of changing the range of the attribute information 40 that is permitted to be browsed (creation date and time and creation location (position information)), and the like. is.

A scene 44 e shows a state in which the person 34 receives the information processing device 10 whose non-display processing has been canceled and looks into the display section 26 a of the information processing device 10 . By canceling the non-display processing by the display control unit 12c, the person 34 can display the display information (image data 32) stored in the storage unit 18 without any restrictions, as shown in the display example scene 50c. , will be available for viewing. Therefore, thumbnails corresponding to the image data 32a to 32e are displayed in the thumbnail display area 52a of the display section 26a, indicating that the display information (image data 32) can be displayed without restriction. That is, it is possible to browse all the image data 32 including the image data 32c of the person 36 photographed at the travel destination that the person 46 did not want the person 34 to browse at first. In the display example scene 50c, for example, the image data 32c is enlarged and displayed from among the thumbnails displayed in the thumbnail display area 52a in the main display area 52b of the display unit 26a. In the example described above, the display control unit 12c displayed the image data 32c as the thumbnail image 32f when restricting viewing of the image data 32 (hidden). In another example, the thumbnail image 32f may be hidden. In this case, it is possible to prevent the person 34, who is a third party, from recognizing the presence of the hidden image data 32, thereby avoiding unnatural thumbnail display.

As described above, according to the information processing apparatus 10, it is not necessary to perform settings such as non-display for each display information (image data 32). In other words, it is possible to easily prevent a third party from peeking at display information that is not intended to be viewed without increasing the work load.

In the above example, as the attribute information 40, it was added when creating the first display information (for example, the image data 32a) displayed on the display device 26 before the change from the person 46 to the person 34 was detected. and the second created position information added when creating the second display information (for example, the image data 32c) that can be displayed on the display device 26 after the person change is detected. An example is shown in which whether or not to display the second display information (image data 32c) is determined based on the result of comparison with the information.

The display control unit 12c can perform non-display processing of display information using other attribute information 40 by setting. For example, the display control unit 12c controls the position information at the time of creation added when the display information (the image data 32 and the created document data) as the attribute information 40 is created, and the current position of the display device 26 acquired by the position detection unit 28. Whether or not to display the display information (the image data 32 and the created document data) may be determined based on the comparison result between the device position information indicating the position. For example, consider the case where the person 46 browses or updates the created document data created at the company at a place other than the company, for example, at home or on a business trip. In this case, when a third party looks into the display device 26 at home or the like, the location information (creation location information) of the company included in the attribute information 40 of the creation information and the location information (creation location information) where the information processing device 10 currently exists ( device location information). As a result, the display control unit 12c can hide the created document while it is being displayed on the display device 26 when a third party tries to look into the created document created by the company. Therefore, it is not necessary to individually set non-display for each piece of display information (image data 32 and created document data). In other words, it is possible to easily prevent information that is not intended for viewing from being peeped at by a third party without increasing the work load. As a result, the security of created documents can be easily improved even at home or on a business trip, where security is low.

In another example, the display control unit 12c is connected to the display information creation device (information processing device 10) added when the display information (image data 32 or created document data) as the attribute information 40 is created. The first network name (for example, the SSID of a WiFi access point that can be connected at work) and the second network name (for example, home (SSID of a Wi-Fi access point that can be connected to the Internet), and whether or not to display the display information (image data 32, created writing style data, etc.) may be determined based on the comparison result. In this case as well, when a third party looks into the display device 26, the location information of the company (first network name) included in the attribute information 40 of the creation information and the location of the current location of the information processing device 10 Information (second network name) is different. As a result, the display control unit 12c can hide the created document while it is being displayed on the display device 26 when a third party tries to look into the created document created by the company. Therefore, it is not necessary to individually set non-display for each piece of display information (image data 32 and created document data). In other words, it is possible to easily prevent information that is not intended for viewing from being peeped at by a third party without increasing the work load. As a result, the security of created documents can be easily improved even at home or on a business trip, where security is low. Even if the position information (latitude and longitude information) is the same, the network name to which the information processing apparatus 10 is connected may be different. For example, in a condominium or building, even if the latitude and longitude information is substantially the same between one's home and neighboring rooms or lobbies, the connected network names may differ. In such a case, even if the attribute information 40 has the same location information, the network name, which is another attribute information, is different. This makes it possible to avoid prying eyes in places other than this, contributing to improved security and enhanced privacy protection.

In another example, the display control unit 12c generates the first display information (for example, the image data 32a) displayed on the display device 26 as the attribute information 40 before the replacement of the person is detected. Added first time information (date of creation, time of creation, etc.) and second time information added at the time of creation of second display information that can be displayed on the display device 26 after detection of a person change Whether or not to display the display information (the image data 32, the writing style data, etc.) may be determined based on the result of comparison with (date of creation, time of creation, etc.). Also in this case, when a third party looks into the display device 26, the time information (first time information) included in the attribute information 40 of the created information and the information that the information processing device 10 can currently display on the display device 26 It differs from the second time information (creation date, creation time, etc.) added when the second display information (for example, the image data 32c) was created. As a result, the display control unit 12c can hide the second time information (for example, the image data 32c) when a third person tries to look into the display device 26. FIG. Therefore, it is not necessary to individually set non-display for each piece of display information (image data 32). In other words, it is possible to easily prevent information that is not intended for viewing from being peeped at by a third party without increasing the work load. As a result, the security of created documents can be easily improved even at home or on a business trip, where security is low.

In another example, the display control unit 12c controls, as the attribute information 40, the face image information of the detected person after detecting the replacement of the person, and the person image as display information that can be displayed on the display device 26. Whether or not to display a person image may be determined based on the result of comparison with face image information included in (for example, the image data 32 or the like). For example, the face image information of the person 34 detected after the person 46 who is the authenticated person (authorized user) of the information processing apparatus 10 is replaced by the person 34 who is the authenticated person, and the display that can be displayed on the display device 26 When the face image information included in the person image (for example, image data 32) as information does not match, the image data 32 including the face image information is not displayed. Conversely, if there is image data 32 containing a person image that matches face image information of person 34, display of that image data 32 is permitted. In other words, when the person 34 himself is shown, viewing is permitted. In this manner, the display control unit 12c can hide the person 34 if the person 34 is not shown in the target image data 32 when the third person tries to look into the display device 26 . As a result, it is possible to easily prevent information that is not intended for viewing from being peeped at by a third party without increasing the work load. That is, it is possible to easily improve security and privacy protection.

In the above example, the display information, for example, the image data 32 and the prepared document data are not displayed. In yet another example, the execution result of an application capable of displaying the execution state on the display device 26 may not be displayed when a person change is detected. For example, if an application such as e-mail receives an e-mail while the information processing apparatus 10 is handed over to a third party, the sender of the e-mail and the content of the preview screen may be seen by the third party. . Therefore, by hiding the execution result as display information based on the attribute information of the application, it is possible to avoid leakage of the execution result of the application. In this case as well, it is possible to easily prevent information that is not intended for viewing from being peeped at by a third party without increasing the work load. As a result, it is possible to easily improve security and privacy protection.

Note that the person detection unit 12b of the embodiment detects a change of person based on a change in the face image information of the person facing the display unit 26a (display area). Compared to the case of determination, the processing load can be reduced, and it is possible to easily detect the replacement of persons.

The flowcharts of FIGS. 5 to 7 are examples of the flow of non-display processing of display information by the information processing apparatus 10. FIG.

FIG. 5 is a flow chart showing processing when the front camera 22 detects a change of persons. The human detection unit 12b constantly detects faces using the front camera 22 and temporarily stores the data. Therefore, the person detection unit 12b detects a person change in a state where it is necessary to detect a person change, that is, in a state where iris authentication by the iris authentication device 24 has been executed and use of the information processing device 10 by an authorized user has been confirmed. is required, first, the face detection table, which is a storage area for face detection data captured by the front camera 22, is cleared (S100). That is, the face detection data remaining in the previous processing cycle (processing cycle before biometric authentication) is once reset. At the same time, the latest updated face detection table is acquired (S102). In the case of the first processing cycle after biometric authentication, the face detection data has already been cleared and does not exist. Therefore, in the first process, for example, the authenticated face detection data acquired by the iris recognition device 24 is written and acquired in the updated face detection table.

Subsequently, the person detection unit 12b performs face detection for detecting the replacement of persons with the front camera 22 (S104). Then, it is confirmed whether the face detection data (single or plural) detected in S104 matches the face detection data in the face detection table acquired in S102 (S106). If the face detection data match (Yes in S106), that is, the face detection data detected in S104 matches the authenticated face detection data, and it can be determined that the person has not been replaced. Therefore, when the completion of the person replacement detection service (for example, the end of use of the information processing apparatus 10) is not notified (No in S108), the process returns to S102, the processes after S102 are executed, and the person replacement detection process is continued. do. Also, when the termination of the face detection service is notified (Yes in S108), for example, when the use of the information processing apparatus 10 is terminated, this flow is once terminated.

In the process of S106, if the face detection data do not match (No in S106), the face detection table is updated with the most recently detected face detection data (S110). In other words, the face detection table is updated with face detection data other than the person whose approval has been affirmed. This face detection table is acquired in the processing of S102 in the next processing cycle. Also, at this time, the time information when the iris authentication (biometric authentication) was performed by the iris authentication device 24 is cleared (S112). In other words, it can be detected that the person using the information processing apparatus 10 (the person looking into the display section 26a) has changed. Thereafter, the authentication is invalidated, the process proceeds to S108, and the process of detecting the replacement of persons is executed until the termination of the face detection service is notified.

Next, an example of the flow of processing for checking whether or not specific display information (image data 32, created document data, etc.) can be displayed will be described with reference to the flowchart of FIG.

The display control unit 12c first turns on the display flags 42 (see FIG. 2) of all display information (image data 32, created document data, etc.) (S200). In other words, once all display information is made available for viewing. Subsequently, the display control unit 12c checks whether the current timing is within a specified time (valid period of biometric authentication) since the last biometric authentication (iris authentication) (S202). If the elapsed time is within the specified time (Yes in S202), it is checked whether the display information includes location information and WiFi AP information (S204). If the display information includes location information or WiFi AP information (Yes in S204), the display control unit 12c can assume that the location information or WiFi AP information of the display information matches the location information of the current location. (S206). In S206, if the position information can be considered to match (Yes in S206), this flow is temporarily terminated. In other words, the state in which all the display information can be browsed is maintained.

In the process of S202, if the elapsed time from the most recent biometric authentication (iris authentication) exceeds the specified time (No in S202), the display flag 42 of the display information (image data 32, created document data, etc.) is turned OFF. (S208). In other words, all display information is made non-display so that it cannot be browsed, and this flow is terminated once. Similarly, in the processing of S204, if the display information does not include the position information or the WiFi AP information (No in S204), the display information (the image data 32 or the created document data, etc.) is turned off (S208). In other words, if there is a possibility that the determination accuracy based on the position information will be lowered, the specific display information is hidden so that it cannot be browsed, and this flow is once terminated. In the process of S206, if the position information cannot be considered to match (No in S206), the display flag 42 of the display information (image data 32, created document data, etc.) that cannot be considered to match the position information is turned OFF. (S208). In other words, it is assumed that the display information is to be viewed at a position different from that at the time of creation, the corresponding specific display information is hidden so that it cannot be viewed, and this flow is temporarily terminated.

Next, an example of the flow of processing for checking whether or not specific image data 32 can be displayed will be described with reference to the flowchart of FIG.

The display control unit 12c first turns on the display flags 42 (see FIG. 2) of all display information (image data 32) (S300). In other words, once all display information is made available for viewing. Subsequently, the display control unit 12c checks whether the current timing is within a specified time (valid period of biometric authentication) after the latest biometric authentication (iris authentication) (S302). If the elapsed time is within the specified time (Yes in S302), it is checked whether the display information includes location information and WiFi AP information (S304). If the display information includes location information and WiFi AP information (Yes in S304), the display control unit 12c controls the location information and WiFi AP information of the display information and the location of the previously displayed display information. It is determined whether the information and the WiFi AP information are close (whether within a predetermined range) (S306). If the position information of the display information or the WiFi AP information is close to the position information of the display information or the WiFi AP information that was displayed immediately before (Yes in S3306), the display control unit 12c can be recognized by the front camera 22. It is checked whether or not the face image data (a plurality of data) can be detected in all the display information (S308). When the face image data (person's face image data) recognized by the front camera 22 can be detected in all the display information (Yes in S308), this flow is once terminated. That is, a state is maintained in which all display information (image data 32) can be browsed.

In the processing of S302, if the elapsed time from the most recent biometric authentication (iris authentication) exceeds the specified time (No in S302), the display flag 42 of the display information (image data 32) is turned OFF (S310). In other words, all the display information (image data 32) is hidden so that it cannot be browsed, and this flow is temporarily terminated. Similarly, in the process of S304, if the display information does not include the location information or the WiFi AP information (No in S304), the display information (image data 32) that does not include the location information or the WiFi AP information The display flag 42 is turned off (S310). In other words, if there is a possibility that the determination accuracy based on the position information will be lowered, the corresponding specific display information is hidden so that it cannot be browsed, and this flow is temporarily terminated. Further, in the process of S306, if the position information cannot be regarded as close (No in S306), the display flag 42 of the display information (image data 32) whose position information cannot be regarded as close is turned OFF (S310). . In other words, it is assumed that the display information is about to be browsed at a position different from the position where the display information was created, and the corresponding specific display information is hidden so that it cannot be browsed, and this flow is temporarily terminated. In addition, in the process of S308, if the face image data recognized by the front camera 22 cannot be detected in the display information (image data 32) (No in S308), the display information (image data 32) that does not have matching face image data ) is turned off (S310). In other words, the specific display information is made invisible so that it cannot be browsed, and this flow is temporarily terminated.

As described above, according to the information processing apparatus 10 of the present embodiment, when the change of the person facing the display area of the display device 26 is detected, the attribute information 40 of the display information (image data 32, created document data, etc.) Therefore, it is not necessary to individually set each display information in advance, and it is possible to easily hide the display information, which is not desired to be seen by a third party.
