Hereinafter, preferred embodiments will be described in detail with reference to the accompanying drawings. FIG. 1 is a block diagram showing a configuration of a communication terminal apparatus according to the first embodiment of the present invention.
As shown in FIG. 1, the communication terminal device according to the present embodiment includes a person estimation rule storage unit 1 that stores a person estimation rule for estimating a person who is looking at an object that is information managed by the communication terminal device, and a person Based on the estimation rule, the person estimation unit 2 that estimates the person who is looking at the object and the person estimated by the person estimation unit 2 determine the processing content for the object, and the object with the determined processing content And an object processing method determination unit 3.

  For communication terminal devices such as mobile phones, for example, the configurations of a transmission / reception unit, a speaker, a microphone, a key operation unit, a display unit, and the like that communicate with the base station device are well-known technologies. The description is omitted in FIG.

  FIG. 2 is a flowchart showing the operation of the communication terminal apparatus according to this embodiment. The person estimation unit 2 of the communication terminal apparatus determines whether or not the situation of looking at the object of the communication terminal apparatus matches the condition of the person estimation rule stored in the person estimation rule storage unit 1 (step S1 in FIG. 2). If there is a person estimation rule that matches the condition, a person who wants to see the object is estimated based on the person estimation rule (step S2).

Then, the object processing method determination unit 3 determines the processing content for the object on the assumption that the person estimated by the person estimation unit 2 sees, and converts the object with the determined processing content (step S3).
The object processing method determination unit 3 does not convert the object or performs default object conversion when there is no rule that matches the condition in step S1 or when a person cannot be estimated (step S4).

Hereinafter, the operation of each component of the communication terminal apparatus will be described in more detail.
The person estimation rule storage unit 1 stores person estimation rules in advance. The person estimation rule is for estimating a person who wants to see an object from information used for person estimation.
Information used for person estimation includes time information for viewing an object, location information for viewing an object, presence information indicating a scene for viewing an object, and a body used for authentication by a person viewing the object. Part information, communication terminal device motion or posture information, instruction content from external wireless device, voice recognition information, password field input content, user explicit setting information, button pressing, communication terminal device state modification There is information.

The person estimation unit 2 estimates a person who wants to see the object based on available information and a person estimation rule.
The object processing method determination unit 3 determines the processing content for the object managed by the communication terminal device, and processes the object with the determined processing content. Examples of the object include a telephone book, mail, user and other person profiles, a public page, a schedule book, a photo, a video, sound, and a target person related file. The object processing method determination unit 3 converts the object so that the relationship between the person estimated by the person estimation unit 2 and the user of the communication terminal device is relatively improved.

  As described above, in the present embodiment, it is not necessary to designate in advance a person to be concealed as a person to be concealed as in the related methods shown in FIGS. Since it can be estimated by the person estimation unit 2, by converting the object on the assumption that the estimated person looks at the communication terminal device, the person who wants to see the object can be viewed without setting a person to be concealed in advance. You can switch the person you want to keep secret. As a result, in this embodiment, it is possible to reduce the number of items that should be set in advance by the user of the communication terminal device, and to further minimize the explicit designation of the person to be concealed on the spot by the user. Therefore, it is possible to obtain the effect of maintaining a stable human relationship while protecting the privacy.

[Second Embodiment]
Next, a second embodiment of the present invention will be described. In the present embodiment, the first embodiment will be described more specifically. FIG. 3 is a block diagram showing a configuration of a communication terminal apparatus according to the second embodiment of the present invention. The same reference numerals are given to the same configurations as those in FIG.

  As shown in FIG. 3, the communication terminal device according to the present embodiment includes a person estimation rule storage unit 1 that stores a person estimation rule in advance, a key operation unit 4, an authentication unit 5, a situation detection unit 6, and motion detection described later. A person estimation unit 2 for estimating a person based on a person estimation rule by using information from at least one of the unit 7, the voice recognition unit 8, the wireless instruction recognition unit 9, and the deformation detection unit 10; Assuming that the estimated person sees, the object processing method determination unit 3 that determines the processing contents for the object, which is information managed by the communication terminal device, and processes the object with the determined processing contents, and the user presses a button or a touch pen Detects the situation such as time and place where an object is to be viewed, and an authentication unit 5 for authenticating a user of a communication terminal device. A situation detection unit 6, a motion detection unit 7 that detects the motion or posture of the communication terminal device, a voice recognition unit 8 that performs voice recognition processing on voice collected from the surrounding environment, and an external wireless device Wireless instruction recognition unit 9 for recognizing instruction contents, deformation detection unit 10 for detecting deformation of a communication terminal device, object storage unit 11 for storing objects such as telephone directory information and sent / received mail, and object processing method determination And an object presentation unit 12 for presenting the object converted by the unit 3 by screen display, reading aloud, or the like.

  For communication terminal devices such as mobile phones, for example, the configuration of a transmission / reception unit, a speaker, a microphone, and the like that communicate with the base station device are well-known techniques, and therefore, these configurations are omitted in FIG. ing.

  FIG. 4 is a flowchart showing the operation of the communication terminal apparatus according to this embodiment. The key operation unit 4, the authentication unit 5, the situation detection unit 6, the motion detection unit 7, the voice recognition unit 8, the wireless instruction recognition unit 9, and the deformation detection unit 10 of the communication terminal device are used to estimate a person who wants to see an object. Available information is acquired (step S10 in FIG. 4).

  The person estimation unit 2 determines whether or not the situation in which the object of the communication terminal device is viewed matches the condition of the person estimation rule stored in the person estimation rule storage unit 1 (step S11). If an estimation rule exists, a person who wants to see the object is estimated based on the person estimation rule (step S12).

Then, the object processing method determination unit 3 determines the processing content for the object on the assumption that the person estimated by the person estimation unit 2 sees, and converts the object with the determined processing content (step S13).
Further, the object processing method determination unit 3 does not convert the object or performs a default object conversion when there is no rule that matches the condition in step S11 or when a person cannot be estimated (step S14).

  After the process of step S13 or S14, the object presentation unit 12 presents the object according to the display method similar to that of the conventional mobile phone (step S15).

Hereinafter, the operation of each component of the communication terminal apparatus will be described in more detail. Similar to the first embodiment, the person estimation rule storage unit 1 stores person estimation rules in advance.
FIG. 5 to FIG. 7 are diagrams illustrating examples of person estimation rules for estimating a person using location and time information.

  The table 20 shown in FIG. 5 associates the human relationship category indicating the relationship between the user of the communication terminal device and the other person with a place or time at which a person belonging to the human relationship category is likely to encounter an object. This is for estimating the human relationship between the user and the person who wants to see the object from the information on the place and time where the user wants to see the object.

  The situation detection unit 6 acquires date information and notifies the person estimation unit 2 using the clock function provided in the communication terminal device. A method of acquiring location information by the situation detection unit 6 will be described later.

  According to the table 20, for example, it is understood that a user's spouse is likely to encounter at home, and a classmate is likely to encounter at school during the daytime. Conversely, if the place where you want to see the object is at home, the person who sees the object is likely to be a spouse, and if the place is at school and the time zone is noon, the person is likely to be a classmate. I understand that. Furthermore, if the place is at home, it can be used as a rule that the probability of being a person trying to see an object is high not only for the spouse but also for children and parents. Note that the time information can be registered directly in the table 20 instead of an abstract time zone like “evening”.

  The table 21 shown in FIG. 6 associates a person's name with a human relationship category or a human relationship group, and is used to estimate a person who wants to see an object from the human relationship with the user. . A person can be estimated by combining the table 20 and the table 21. For example, if the place is home, the table 20 indicates that the person who is looking at the object is one of a spouse, a child, and a parent, and “Yuki Sato” is registered in the table 21 as the name of the spouse. Therefore, it can be seen that the probability that the person is “Yuki Sato” is high. If the place is a company, the table 20 shows that the person who sees the object is a company colleague, and “Taro Suzuki” is registered in the table 21 as the name of the company colleague. It turns out that the probability of being “Taro Suzuki” is high.

The human relationship category includes spouse, child, parent, lover, friend, company colleague, classmate, circle companion, family, relative, and the like.
Moreover, since gender information is also highly useful as a secret conversion method, gender information may be added to the human relationship category. For example, if the user of the communication terminal device is male and the person who wants to see the object is female, the worries unnecessary for the person who wants to see the object by converting the name of the acquaintance of the user's female to a male name There is an effect that safety can be improved so as not to be applied. In this way, by directly associating with a name, the intimacy between the user and the person is displayed higher than the actual one, and the mail and address book from the person are not changed and suspicious. You can change your email and address book.

  The person estimation rules as shown in FIGS. 5 and 6 can be prepared in advance by the manufacturer of the communication terminal apparatus or can be edited by the user. By allowing the user to edit the person estimation rule, a person estimation rule unique to the user can be created, and the effect of improving the person estimation accuracy can be obtained. By informing the user of the person estimation rule, an effect that the user can use with confidence can be obtained.

  The table 22 shown in FIG. 7 associates a location with a base station ID, and estimates a location where an object is to be viewed from a base station ID that is an identifier of a mobile phone base station, a wireless LAN spot, or the like. belongs to.

  The situation detection unit 6 can estimate the location by searching the table 22 using an identifier such as a mobile phone base station or a wireless LAN spot as a search key. Of course, the situation detection unit 6 can also estimate the location by a direct method such as latitude and longitude information by GPS (Global Positioning System) without using the table 22.

  FIG. 8 is a diagram illustrating another example of a person estimation rule for estimating a person using location and time information. The table 23 shown in FIG. 8 associates a person's name with a place and time at which the person is likely to encounter the person. It is for estimating the human relationship. According to the table 23, it is possible to directly estimate a person from information such as base station ID, latitude / longitude information, time, etc., instead of an attribute having a meaning such as school or home as a place condition. Similar to the table 20, the time information can be directly registered in the table 23 instead of an abstract time zone like “evening”.

  FIG. 9 is a diagram illustrating another example of a person estimation rule for estimating a person by using location and time information, and illustrates an example in which the rule is not embedded in a program but in a data format such as a table. FIG. In this manner, the person estimation rule can be embedded in a program instead of a readable format such as a data file.

  FIG. 10 is a diagram illustrating an example of a person estimation rule for estimating a person by using presence information indicating a scene where a communication terminal device is to be viewed. A table 24 shown in FIG. 10 associates a human relationship category with a presence easily encountered by a person belonging to the human relationship category, and is used instead of the table 20 described above. In this way, in addition to estimating a person directly from a place or time zone, it is also possible to estimate a person from abstract presence information.

  The situation detection unit 6 estimates presence information from date information, for example. In addition, the situation detection unit 6 can also acquire presence information designated by the user. By letting the user specify presence information, the situation can be known at a level that cannot be detected by a conventional sensor. Presence information is not limited to words such as “business” and “private”, but may be pictures or icons. Information such as “in manner mode” and “in drive mode” specified by the user with respect to the communication terminal device can also be acquired as presence information.

  FIG. 11 is a diagram illustrating an example of a person estimation rule for estimating a person using information related to acceleration / posture of a communication terminal device such as how to swing, vibration, acceleration, angular acceleration, speed, angle, posture, and magnetic field. is there. The table 25 shown in FIG. 11 associates a person's name with information on how to swing and position a communication terminal device that has a high probability of being performed by that person.

  The motion detection unit 7 acquires information such as how to shake the communication terminal device, vibration, acceleration, angular acceleration, speed, angle, posture, magnetic field applied to the communication terminal device, and the like by using an internal sensor (not shown). 2 is notified.

  According to the table 25, even when a person other than the user shakes the communication terminal apparatus or when the user of the communication terminal apparatus shakes, the secret mode switching can be made effective for both. For example, if the user shakes the communication terminal device vertically, the communication terminal device regards the person who shakes his / her device as “Taro Suzuki”, and thus the secret mode (object processing) for this person is activated. Thereby, the user can conceal the information of the communication terminal device from this person. Since there is a low possibility that the communication terminal device is related to shaking the communication terminal device and switching to the secret mode, there is an effect that the communication terminal device can be switched without being noticed.

  FIG. 12 is a diagram illustrating an example of a person estimation rule that estimates a person using body part information used for authentication. The table 26 shown in FIG. 12 associates a person's name with body part information that the person uses for authentication. The body part information registered in the table 26 is registered in a form that is easy to understand for humans, such as the right hand index finger and the right eye, and actually, in correspondence with these part information, fingerprints, iris patterns, Biometric information such as a vein pattern is registered in the person estimation rule storage unit 1. Further, the body part information and the biological information to be registered do not have to be those of a person, but may be those of the user of the communication terminal device.

  The authentication unit 5 obtains information about the fingerprint, iris pattern, and vein pattern of the person by a fingerprint sensor and a camera (not shown) when authenticating the person who is looking at the object, and notifies the person estimation unit 2 of the information.

  According to the table 26, a person can be estimated from the acquired fingerprint, iris pattern, and vein pattern. Moreover, according to the table 26, even when using the body part of a person other than the user or when using the body part of the user of the communication terminal device, the secret mode switching can be made effective for both. For example, when the user performs authentication using the right hand pointing finger, the communication terminal apparatus regards the authenticated person as “Yuki Sato”, and thus the secret mode for this person is activated. Thereby, the user can conceal the information of the communication terminal device from this person. Since there is a low possibility that the body part used for authentication is related to the secret mode, it is possible to switch without being noticed by the person.

FIG. 13 is a diagram illustrating an example of a person estimation rule for estimating a person using speech recognition information such as a keyword, a sentence, and a sentence. A table 27 shown in FIG. 13 associates a person's name with a speech recognition word that is likely to be uttered by the person.
The voice recognition unit 8 performs voice recognition of voice collected by a microphone (not shown), and notifies the person estimation unit 2 of the recognized words.

  According to the table 27, a person can be estimated from the speech recognition word acquired by the speech recognition unit 8. Further, according to the table 27, the user can not only switch to the secret mode by speaking to the communication terminal device like a password, but also can switch to the secret mode by a word in conversation between the user and another person. For example, when the user utters the word “brass band”, the communication terminal apparatus regards the person as “Yuji Tanaka”, and the secret mode for this person is activated. Thereby, the user can conceal the information of the communication terminal device from this person. Since it is unlikely to be noticed that there is a connection between the conversation between humans and the secret mode, there is an effect that it is possible to switch without being noticed. It is also possible to increase the accuracy of estimation by combining speech recognition words with other information.

Note that a table in which the name of the person and the instruction content of the external wireless device are associated with each other may be registered in the person estimation rule storage unit 1 as a person estimation rule. According to this table, a person can be estimated from the instruction content of the external wireless device.
The wireless instruction recognition unit 9 acquires the instruction content of the external wireless device from the information received by the transmission / reception unit (not shown).

In addition, a table in which the name of the person and the state deformation of the communication terminal device are associated may be registered in the person estimation rule storage unit 1 as a person estimation rule.
