  In the present invention, an event refers to any object that can be observed by a person and that can be viewed later on information that records the object. An event includes, for example, a conversation, a conference, a lecture, a demonstration, an experiment, or a phenomenon that a person can observe without using an instrument. The event also includes playing back a board written at a meeting or a lecture, or content including audio or images. Furthermore, it includes a conversation over a communication network, a meeting, a chat with characters, and collaborative creation of document data.

  EMBODIMENT OF THE INVENTION Below, the form for inventing is demonstrated in detail with reference to drawings. In the drawings, the same or corresponding parts are denoted by the same reference numerals.

(Embodiment 1)
FIG. 1 is a block diagram showing a configuration example of an information protection apparatus according to Embodiment 1 of the present invention. The information protection apparatus 1 includes an event information acquisition unit 11, an identification information acquisition unit 12, a necessity information acquisition unit 13, a disclosure control unit 14, a confirmation unit 15, a storage unit 16, and a transmission unit 17.

  The event information acquisition unit 11 records a predetermined event including information that the user wants to protect. For example, the event information acquisition unit 11 acquires a record of an event recorded by the recording unit 101 as event information. The recording unit 101 includes, for example, a camera that captures an image or video and converts it into digital or analog image data. A microphone or the like may be used. In addition, the event captures a board document created at a conference or lecture, an agent that captures the content reproduced at the conference or lecture, or a document data created jointly by a conference or chat via a communication network. Agents that record in are also included.

  The identification information acquisition unit 12 acquires identification information including a tag ID from the tag held in the object that is the target of the event. As shown in FIG. 1, when the tag is an RF tag 102, a data receiving unit (not shown) having an antenna is provided, radio waves are transmitted to and received from the RF tag 102, and radio waves are demodulated and detected. Thus, the identification information of the RF tag 102 can be acquired. Further, the identification information acquisition unit 12 can acquire the position information of the RF tag 102 by calculating the arrival direction based on the time difference when the radio wave reaches the antenna when acquiring the identification information. .

  When the identification information acquisition unit 12 does not use a wireless communication method using an electromagnetic field or radio waves like the RF tag 102 for the tag held by the target object, for example, when using a two-dimensional barcode, the event When the event information is acquired by the information acquisition unit 11, the video may be scanned, the two-dimensional barcode may be read, and the identification information may be acquired.

  A tag having identification information is attached in advance to an object to be an event target. For example, when the target is a personal computer or the like, a tag may be attached to one corner of the display screen, and the tag may be attached to the object in advance. For example, if the subject is a person, an ID tag is attached to a holder such as a type of admission permit that is lowered to the neck. By having a holder, identification information can be attached to the person who is the object, and tagging can be prevented from being forgotten.

  The necessity information acquisition unit 13 associates the event information acquisition unit 11 with a specific range in the record acquired by the identification information acquisition unit 12, and is associated with the identification information acquired by the identification information acquisition unit 12. Mask level information indicating whether or not the recorded information needs to be concealed is acquired. In particular, the matching unit 13a associates the event information acquisition unit 11 with a specific range in the record acquired by the identification information acquisition unit 12.

  The specific range refers to a control range when performing the disclosure control process. When the event record is an image, image processing is performed to conceal part or all of the target object in the record. At this time, if the target in the recording is a person, for example, a specific image area including a specific part such as a face or eyes or a person is a specific range. Some ranges correspond to specific ranges. In addition, when the event is recorded as sound, for example, a recording portion while the target object (person) is generating sound corresponds to a specific range.

  For example, it is assumed that an object with a tag B is set in advance as an object to be protected, and identification information corresponding to the tag B is stored in the storage unit 16 of the information protection apparatus 1. At this time, it is assumed that the event A including the tag B is recorded in the information acquired by the event information acquisition unit 11. First, the control unit (not shown) of the information protection device 1 records the event A based on the identification information of the tag B acquired from the recording of the event A or the combination of the position information and identification information of the tag B acquired from the outside. The matching unit 13a associates a specific range, which is a range to be protected by the tag B, with the recording of the event A.

  The disclosure control unit 14 records the information acquired by the event information acquisition unit 11 in association with the identification information acquired by the identification information acquisition unit 12 according to the mask level information acquired by the necessity information acquisition unit 13. Mask a specific range. Specifically, masking is performed by performing image processing if the information is an image and performing sound processing if the information is sound.

  The confirmation unit 15 acquires a destination for transmitting a record of a predetermined event associated with the identification information acquired by the identification information acquisition unit 12. The destination is an individual ID of the terminal 103 or the like having a display unit, and information is transmitted to a specific device based on the individual ID, and the user confirms (plays back) a record of a predetermined event using the device. And browse).

  The storage unit 16 stores information such as a record of an event acquired by the event information acquisition unit 11 and processed information that is disclosed and controlled by the disclosure control unit 14. Further, information such as identification information corresponding to the tag ID acquired by the identification information acquisition unit 12, tag position information, other information such as mask level information stored in advance in the information protection device 1, and information protection as needed. Information acquired by the device 1 is stored.

  The transmission unit 17 transmits the record of the event controlled by the disclosure control unit 14, that is, the processed information stored in the storage unit 16, to the destination acquired by the confirmation unit 15. For example, the data is transmitted to a designated terminal 103 such as a personal computer or a mobile phone.

  FIG. 2 is a diagram illustrating an example of position information of tag information in the first embodiment. For example, the identification information acquisition unit 12 can receive a radio wave transmitted to the RF tag 102 via an antenna, and can acquire the tag ID of the tag and tag position information from the arrival direction of the radio wave. The position information is composed of three-dimensional position information and three-axis posture coordinates.

  FIG. 3 is a diagram showing an example of mask level information of the tag information in the first embodiment. The range is a control range when performing the disclosure control process, and refers to a specific range. For example, with respect to a tag attached, it indicates whether the range for disclosure control is the whole or a part. In addition, when the person with the tag is a person, it indicates whether the disclosure control range is a face, eyes, or the entire body. The disclosure control method is a mask processing method, and in the case of an image, there are painting and mosaic processing. In the case of voice, a sound effect may be applied, silenced, or changed. The priority is for determining the order of processing when the disclosure control processing is performed. The higher the numerical value of the priority, the earlier the processing. If the tag IDs are close to each other and the predetermined range to be controlled for disclosure overlaps, the mask processing is first performed around the tag ID with a high priority value. The mask process is displayed so as to be overwritten on the masked part.

  For the mask level information, a tag ID, a condition on how much the object to which the tag is attached should be protected, and how it should be protected (disclosure should be controlled) are set. Is stored in the storage unit 16 in association with the tag ID. The information protection device 1 can acquire the tag mask level information by referring to the mask level information of the tag stored in the storage unit 16 by acquiring the tag ID simultaneously with the position information by the identification information acquisition unit 12. it can.

  FIG. 4 is a diagram illustrating an example of event information in the first embodiment. FIG. 4A is an image in which an event is recorded by the recording unit 101. FIG. 4B and FIG. 4C are images obtained by subjecting the recording to processing by disclosure control in the disclosure control unit 14. In FIG.4 (b), the object provided with the tag is uniformly painted and the information is protected. In FIG. 4 (c), one is a mosaic as a whole and the other is painted around the four sides like a frame. For example, masking only a part without masking the whole is applied to a case where it is desired to record a television image, but to hide only the manufacturer name described on the television.

  FIG. 5 is a diagram illustrating an example of observed information of the tag information in the first embodiment. The identification information acquisition unit 12 receives tag information from the RF tag 102, and records the date and tag ID.

  FIG. 6 is a diagram illustrating an example of a confirmation result of the tag information in the first embodiment. The result of confirming whether image processing has been performed is additionally described in the observed information shown in FIG. The confirmation result indicates whether or not the user 103 is properly protected with respect to the record subjected to the process by the disclosure control in the information protection apparatus 1 and shows the result. A mechanism in which a user confirms disclosure control at the terminal 103 is fed back to the protection information device 1, and a control unit (not shown) of the protection information device 1 instructs the disclosure control unit 14 to reset the mask level. May be.

  FIG. 7 is a diagram illustrating an example of event information destinations according to the first embodiment. A destination that is a transmission destination of information associated with the identification information is stored in the storage unit 16 in advance. The destination indicates an identification code of the terminal 103 used by the user who uses the recorded information.

  FIG. 8 is a flowchart showing an example of the operation of the information protection apparatus according to the first embodiment. First, the event information acquisition unit 11 of the information protection device 1 acquires the event information recorded by the recording unit 101 (step S11). Further, the identification information acquisition unit 12 acquires identification information such as the tag ID and position information of the RF tag 102 (step S12).

  The matching unit 13a of the necessity information acquisition unit 13 associates the information acquired by the event information acquisition unit 11 and the identification information acquisition unit 12 with a specific range in the recording (step S13). And the necessity information acquisition part 13 complete | finishes matching with the information and specific range in the matching part 13a, and mask level information which determines disclosure control of identification information from tag ID of the identification information contained in the event information Is acquired (step S14).

  If the mask level information includes identification information having a tag ID to be protected (step S15; YES), the disclosure control unit 14 performs mask processing on the target event information based on the mask level information. Perform (step S16), and store the processed information in the storage unit 16 (step S17). If the mask level information does not include identification information having a tag ID to be protected (step S15; NO), the information acquired by the event information acquisition unit 11 is stored as it is in the storage unit 16 (step S17).

  The confirmation unit 15 acquires a destination to which the processed information is sent, which is associated with the identification information (step S18), and the transmission unit 17 transmits information to the destination (terminal 103) (step S19). If there is information to be recorded next (step S20; YES), the process returns to step S11 and the process is repeated. If there is no information to be recorded next (step S20; NO), the information protection operation process is terminated.

  As described above, according to the first embodiment, it can be confirmed whether or not the object to be protected is protected in the recording.

  Attaching a tag for identification to the information that the user wants to protect in advance, and inputting the identification level and mask level information indicating the necessity of concealment, to record the event The recording can be performed by masking a specific range. In addition, since the masked record is transmitted to a display device such as a corresponding terminal, it is possible to easily confirm whether or not predetermined protection is performed on the event record.

  Specifically, an ID tag is attached to a holder such as an entrance permit that is lowered to the neck, and the mask level information disclosure control method corresponding to the ID tag is set to mosaic a predetermined range including the tag. Keep it. Information can be easily protected by having the user himself / herself use the admission permit with the ID tag attached when visiting. As a result, it is possible to reduce the risk of privacy infringement and the leakage of confidential information. In addition, it is possible to display on the spot how the information is actually protected, and the user can easily confirm whether or not the information is protected.

(Embodiment 2)
FIG. 9 is a block diagram showing a configuration example of the information protection apparatus according to Embodiment 2 of the present invention. In addition to the information protection apparatus 1 according to the first embodiment, the information protection apparatus 1 acquires the position of the recording unit 101 from which event information is acquired, thereby acquiring the positions of the object to be protected and the recording unit 101. The relationship and the relative positional relationship of the plurality of recording units 101 can be known, and the position of the object included in the event information can be acquired. In addition, when the user confirms with the terminal 103 that the protection is insufficient, a function of feeding back the result to the information protection apparatus 1 is additionally provided.

  The information protection apparatus 1 according to the second embodiment includes a position information acquisition unit 18 and a reception unit 19 in addition to the configuration of the first embodiment. In addition, the terminal 103 represented as the destination to which the result is transmitted is the terminal 104 with an input unit having an input unit function. Other configurations are the same as those of the first embodiment.

  The position information acquisition unit 18 acquires the position information of the recording unit 101. In addition, it is preferable to acquire recording means such as a video camera and a microphone. When the user using the information protection apparatus 1 confirms the information with the terminal 104 with the input unit, the recording unit and the position information are displayed together with the event information recording, so that the user can select which recording unit 101 It is possible to grasp from which position recording is performed.

  Also, by providing the position information acquisition unit 18, the positional relationship between the object to be protected and the recording unit 101 and the relative positional relationship of the plurality of recording units 101 can be known, and the position of the object included in the event information is acquired. can do. In particular, this is effective when a plurality of recording units 101 are provided in a range in which the same event is recorded. When the identification information acquisition unit 12 specifies predetermined identification information for event information acquired by the event information acquisition unit 11 via at least one recording unit 101, for event information acquired by another recording unit 101 However, the disclosure control unit 14 can perform disclosure control and mask processing on predetermined identification information included in the record. By providing the position information acquisition unit 18 and performing control as described above, it is possible to perform mask processing more reliably for a specific range including predetermined identification information.

  In the receiving unit 19, a user who sees information displayed on the terminal 104 with an input unit via the transmission unit 17 inputs an evaluation for the presence or absence of protection to the terminal 104 with an input unit, and receives the evaluation result. For example, the observed information shown in FIG. 5 is displayed on the terminal 104 with the input unit together with the processing information shown in FIG.

  The user confirms the displayed information, checks whether necessary information in a specific range is protected, and inputs the result in a format like the confirmation result shown in FIG. If all the reception units 19 are OK, the reception unit 19 transmits information indicating that there is no problem to a control unit (not shown) of the information protection apparatus 1. When NG is included, the information is transmitted to a control unit (not shown) of the information protection device 1 and controlled to the storage unit 16 and the disclosure control unit 14 by an instruction from the control unit. Then, the masking process is performed in a specific range by the newly set method for updating the mask level information in the storage unit 16 and recording the event information in the disclosure control unit 14. Specifically, the update of the mask level information is the mask level information of the tag information shown in FIG. 3, and the disclosure control, that is, the mask processing, is performed by changing the setting of filling the entire 1 m square to the setting of the entire filling. It means changing the method.

  FIG. 10 is a flowchart illustrating an example of the operation of the information protection apparatus according to the second embodiment. The basic operation is the same as that of the first embodiment, and step S31 is added between step S11 and step S12. Further, Step S41 and Step S42 are additionally provided between Step S19 and Step S20.

  In step S31, the recording means and position information of the recording unit 101, which is information of the recording unit 101, is acquired by the position information acquisition unit 18 (step S31). The acquired position information and the recording means of the recording unit 101 store and transmit together with the corresponding event record and processing information. That is, the information described in the storage operation (step S17) and the transmission operation (step S19) is information of the recording unit 101, in addition to the processing information obtained by masking the event information. Are stored and transmitted together.

  Steps S41 and S42 will be described. When the transmission of the information including the recording position information in step S19 is finished, the receiving unit 19 confirms whether or not a result is input from the user. Here, if there is an input of a result of NG (step S41; YES), the control unit (not shown) of the information protection device 1 assumes that the information mask is insufficient, and the mask level information stored in the storage unit 16 Is updated (step S42). For example, the disclosure level control method corresponding to the tag ID input as NG is updated from the mask processing unnecessary to the entire mosaic. Also, the mask level information is updated from the setting of 30 cm square filling around the tag position to the setting of 50 cm square filling around the tag position for the position to be masked by the disclosure control corresponding to the tag ID that is partially inputted as NG. May be. For the mask level information when NG is input in advance, a condition on how to change the setting is input, and in the case of NG, it may be set to be a more preferable condition by user selection. It doesn't matter.

  When the mask level information is updated (step S42), the necessity information acquisition unit 13 acquires mask level information for determining the disclosure control of the identification information again (step S14). Recording and transmission and information protection operation processing are performed.

  After the transmission of the information including the recording position information (step S19), if there is no NG result input (step S41; NO), if there is information to be recorded next (step S20; YES), the process goes to step S11. Return and repeat the process. If there is no information to be recorded next (step S20; NO), the information protection operation process is terminated.

  In step S41, when the user inputs NG using the terminal 104 with the input unit, the mask level information is updated (step S42). However, the determination method is particularly limited to the above-described method. do not do. As a determination method, it is considered that there is no problem when a predetermined time has elapsed from the transmission of information (step S19), or that there is no problem only when OK determination is input for all items. It is only necessary to be able to determine whether or not favorable protection is provided to the user with respect to event recording, such as inputting contents for updating mask level information for NG.

  As described above, according to the information protection apparatus of the second embodiment, it can be easily confirmed whether or not the object to be protected is protected in the recording.

  By transmitting the position of a recording unit such as a camera that records an event together with the recording of the event, the user can know which recording unit is recording. In addition, when recording with a plurality of recording units, at least one recording unit recognizes the tag even if the tag attached to the object to be protected cannot be recognized by any of the recording units. This makes it possible to share tag position information. Since the tag position can be extracted and the position of the target object to be protected can be acquired based on the correlation between the positions of the recording units, as a result, the target object to be protected is masked for the recording of the events acquired by all the recording units. Can be applied.

  Further, by feeding back the result confirmed by the user to the information protection device, it becomes possible to update the mask level information for the protection target that seems to be insufficiently protected and to perform mask processing preferable for the user. The preferred process is to change the disclosure control method, such as blurring and mosaic, or to change the predetermined range, to ensure sufficient protection for the information that you want to protect. This means that the information is processed so that the disclosure becomes clear.

  In the present embodiment, the recording unit has been described for a device that records an image such as a camera. However, the recording unit may be a voice recording such as a microphone. Moreover, it may be a combination of images and sounds such as video. In the case of audio, mask processing can be performed by methods such as deleting or changing the sound, or applying sound effects. In addition, mask level information can be arbitrarily set, such as masking only audio and leaving the image intact, masking only the image and leaving the audio intact, or masking both. The disclosure control to be performed is preferably performed corresponding to the set mask level information.
