METHOD FOR RELEASING IN CHILD LOCK AND ITS APPARATUS}

The present invention relates to a method and a device for releasing a child lock, and when the release signal for the set child lock is generated, the child lock can be released when the face photographed by the camera coincides with the registered parental control face. And a device thereof.

When children watch pornographic or violent or adult programs, they are disturbed by mental stimuli and hurt their emotional growth. Although it is classified by grade (eg, 19 years, 15 years, 12 years old, etc.), most children are exposed to the above-mentioned program when they go out due to unavoidable circumstances. The situation is watching in an unauthorized state.

Therefore, the video reproducing apparatus is provided with a child lock function for each channel, and when the child lock function is set, playback and output of the corresponding channel is prevented.

This child lock function is set up to protect children from dangerous and indiscriminate media information in many electronic devices, and goes beyond simply performing the inherent functions of the electronic device to protect children from indiscriminate mass media or dangerous electronic devices. It is provided to protect. Therefore, the child lock function is added in the service level of the product, but as children's protection level is gradually strengthened recently, the child lock function is acting as another important function in the product.

However, as described above, the conventional child lock function is configured such that the child lock function set is released by the decryption key when the encryption for releasing the child lock is accidentally exposed and found to the children. Therefore, by using the exposed decryption key, the parental authority releases the child lock function set to curiosity while going out, watching pornographic or violent or adult programs, causing disabilities by mental stimuli, and causing a lot of damage to the mental emotion in the growth process. There is a problem to wear.

Therefore, the technical problem of the present invention has been devised to solve the above-mentioned problems, and when the release signal for the set child lock is generated, the child lock when the face photographed by the camera and the registered viewer limiter face coincide. Provided are a method and a device for releasing a child lock to release the child lock.

According to the present invention, there is provided a method of releasing a child lock, comprising: setting a child lock cipher, photographing a recognition object using a camera when a decryption key for releasing a child lock cipher is input; And comparing the image of the subject to be recognized with the image of the pre-stored viewer limiter, and releasing the child lock password.

In addition, the child lock release device according to the present invention, when the storage unit for storing the set child lock password, and the decryption key for releasing the set child lock password is inputted to acquire the recognition target imaged by the camera And a detecting unit and a control unit releasing the child lock cipher when comparing the captured recognition target image with a previously stored image of the viewer restriction authority.

According to the present invention, when the release signal for the set child lock is generated, the child lock is released when the face photographed by the camera and the registered parental control face coincide, so that even if encryption is accidentally exposed as before, child lock It does not turn off, so you can't watch pornographic, violent, or adult programs, which helps your child's emotional well-being.

In addition, the present invention prevents children from releasing child lock by releasing child lock only when the face photographed using the camera coincides with the registered parental control face even when the child lock is set by encryption. There is an advantage to this.

Hereinafter, with reference to the accompanying drawings will be described in detail the operating principle of the present invention. In the following description of the present invention, if it is determined that a detailed description of a known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted. The following terms are defined in consideration of the functions of the present invention, and may be changed according to the intentions or customs of the user, the operator, and the like. Therefore, the definition should be made based on the contents throughout the specification.

The input unit 10 includes various function keys, numeric keys, character keys, and the like, and may transmit various key signals generated in response to the manipulation of the viewer to the controller 20.

In addition, the input unit 10 selects a menu signal restricted by a parental control authority (eg, a parent or grandmother) to restrict viewing in a home with children or teenagers as a key signal for setting a child lock, for example, a function key. In response, the parental control menu key signal may be input to the controller 20 in response to the selection operation.

In addition, when the input control unit 10 displays the parental control selection menu through the output unit 50, the parental control holder can select any desired key signal, for example, a combination of a numeric key and a character key, for setting a child lock password. If an encryption key (e.g., a password set for encryption) is set and a channel to which viewing is to be restricted is selected, the encryption key signal and the channel key signal are transmitted to the control unit 20 in response to the selection operation. You can enter Here, the encryption key may be set differently for each channel.

In addition, when the input unit 10 selects a set key signal for unlocking the set child lock, for example, a decryption key (for example, a password set for decryption) composed of a combination of numeric keys and letter keys, In response to the selected operation, the decryption key signal can be input to the control unit 20.

When the parental control menu key signal for child lock setting is input from the input unit 10, the controller 20 may provide pre-programmed parental control selection menu data to the OSD unit 30.

In addition, when the encryption key signal and the channel key signal for setting the child lock encryption are input from the input unit 10, the control unit 20 sets the child lock encryption using the encryption key signal and the channel key signal and stores the storage unit. 70 can be provided.

In addition, the controller 20 selects a channel to be watched by the viewer when the power is turned on. In this case, if the channel selected by the viewer is a channel for which the viewer has set a viewing restriction, the controller 20 When a menu for inputting the decryption key is output through the OSD unit 30 and the output unit 50, when a decryption key for decryption of the child lock set from the input unit 10 is input in response to the output, the camera ( S1) to provide an image pickup signal, and in response to the image pickup signal, a captured image (eg, a viewer limiter or a parental control box) and a viewer limiter previously stored in the storage unit 70 in response to the image pickup signal. When the child's video is matched (e.g., parental or grandmother as parental restriction), the child lock code set in the parental lock is released, and the tuned to the channel selected by the viewer. For example, the tuner 80 may be controlled to allow the user to watch the corresponding channel.

In addition, in response to the output, when the decryption key for canceling the child lock decryption set from the input unit 10 is input, the control unit 20 provides an imaging signal to the camera S1, and in response to the provided imaging signal. If the input image is not compared with the images of the viewers who are pre-stored in the storage unit 70, for example, to inform that the child lock password set as the captured image is a parental control box cannot be released. The warning message may be provided to the OSD unit 30.

The OSD unit 30 OSD-processes a warning message for notifying that a menu for inputting parental control selection menu data and a decryption key input from the control unit 20 and the set child lock encryption cannot be released. Can be provided to

When the current broadcast program is tuned and inputted, the decoding unit 40 decodes the inputted broadcast program, and then displays the parental control selection menu data or the decryption key input from the OSD unit 30 to the decoded broadcast program. A warning message for notifying that the user cannot input the menu or the set child lock cipher may be mixed and provided to the output unit 50.

The output unit 50 is a monitor such as all means for output, for example, an LCD, a PDP, an OLED, a cathode ray tube, and the like, and the viewing limit selection menu data or the decryption key input from the decoding unit 40 or the OSD unit 30. A warning message for notifying the user that the user can input the menu or the set child lock password can be output so that the viewer can watch.

The detection unit 60 may obtain a face image (eg, a parental control person or a parental control box) that is a recognition target captured by a camera S1 capable of acquiring a visible / infrared face image and provide the same to the control unit 20. have.

The storage unit 70 may store a child lock password (for example, an encryption key signal is set to encryption for each channel corresponding to the channel key signal) input from the controller 20.

The tuner 80 may switch from the tuning standby state to the tuning state according to the tuning control of the controller 20 and provide the decoding unit 40 with a broadcast program in which the target audience tunes to a desired program. If there is no tuning control of), you can switch from tuning status to tuning standby status.

Therefore, in the present invention, when the release signal for the set child lock is generated, the child lock is released when the face photographed by the camera and the registered parental control face coincide, whereby encryption is accidentally exposed as before. Even if the child lock function is not released, it is very helpful for children's mental emotions because they cannot watch pornographic or violent or adult programs.

Next, a process of releasing the child lock in the present embodiment having the above-described configuration will be described.

2 is a flowchart sequentially illustrating a method of releasing a child lock according to a preferred embodiment of the present invention.

First, the parental control authority (eg, a parent or grandmother) restricts the viewing of a channel that is unnecessary for a parental box, for example, an obscene or violent or adult program that is restricted to a parental box, for example, by using the input unit 10. When the parental control menu key is selected, the parental control menu key signal may be transmitted to the controller 20 in response to the selection operation.

The control unit 20 receiving the parental control menu key signal may provide the OSD control unit 30 with the preset parental control selection menu data. The OSD unit 30 may OSD-process the parental control selection menu data input from the controller 20 to provide the decoding unit 40.

Then, when the current broadcast program is tuned and inputted to the parental control selection menu data input from the OSD unit 30, the decoding unit 40 may mix the inputted and decoded broadcast program to provide it to the output unit 50. Can be.

When the parental level selection menu is displayed through the output unit 50, the parental control holder uses the input unit 10 to set a desired key signal, for example, a combination of a numeric key and a letter key, to set the child lock password. When an encryption key (e.g., a password set for encryption, etc.) is set and a channel to which viewing is restricted is selected, an encryption key signal and a channel key signal are sent to the control unit 20 in response to the selection operation. Can be delivered. Here, the encryption key may be set differently for each channel.

When the encryption key signal and the channel key signal for setting the child lock encryption are input from the input unit 10, the controller 20 sets the child lock encryption using the encryption key signal and the channel key signal (for example, the corresponding channel). In response to the key signal, an encryption key signal is set to encryption for each channel (S201), and stored in the storage unit 70.

In this way, the power is turned off in a state in which the channel to be restricted for viewing is set with the encryption key.

Thereafter, the viewer (eg, parental limiter or parental control box) turns on the power for viewing while the power is turned off, and then selects a channel that the viewer wants to watch. If the restrictor is a channel for which the parental control is set, the controller 20 may output a menu for inputting a decryption key through the OSD unit 30 and the output unit 50.

The controller 20 may determine whether a decryption key for child lock decryption, which is set from the input unit 10, is input in response to a menu output for inputting the decryption key (S203).

If the decryption key is not input in the result of the determination (S203), since the tuner unit 80 cannot be controlled in a situation where the viewer does not know the decryption key, the channel is not tuned to the desired channel, and thus the corresponding channel is not tuned. Viewing may be restricted (S205).

On the other hand, when the decryption key is input in the result of the determination (S203), the decryption key set by the parental restriction authority is exposed to the camera S1 in a situation in which the decryption key is exposed due to a mistake of the parental restriction authority (S203). S207).

The camera S1 may capture an object to be recognized according to an image pickup signal input from the controller 20. Then, the detection unit 60 may acquire (S209) a face image of a viewer, who is a recognition target captured by the camera S1 (eg, a viewer limiter or a parental control box), and provide the same to the controller 20. .

In the control unit 20, the captured image input from the detection unit 60 (eg, the parental control box is a face image of the parental control authority) and the image of the parental control authority previously stored in the storage unit 70 (eg, parental control). As the right holder, it can be checked (S211) for comparison with the parent or grandmother.

In the result of the check (S211), if it does not match (for example, the captured image is a parental control box limited viewing), a warning message for notifying that the child lock password can not be released can be provided to the OSD unit 30. . Then, the OSD unit 30 processes the warning message for notifying that the child lock password inputted from the controller 20 cannot be released, and is confirmed by the viewer through the decoding unit 40 and the output unit 50. It can be output (S213).

On the other hand, in the result of the check (S211), if the match (for example, the image capturing the image is limited viewer) releases the set child lock password (S215), and tunes to the channel selected by the viewer to broadcast the desired channel The tuner 80 may be controlled to allow viewing. Then, the tuner 80 outputs the program to be viewed by the viewer through the decoding unit 40 and the output unit 50 according to the tuning control of the controller 20 through the decoding unit 40 and the output unit 50 (S217). can do. Here, the comparison between the captured image and the pre-stored image is performed using face recognition technology, which is a known technique.

On the other hand, in the embodiments of the present invention has been described with respect to the method and apparatus for setting and releasing the child lock to limit the viewing of the broadcast program tuned through the tuner unit 80, the present invention is not necessarily limited thereto. On the contrary, the viewer may play the video stored in a storage unit (eg, a hard disk drive (HDD)) as in a DVR, or may store and play the video such as a compact disk (CD), a DVD, or a video cassette and play the video. As described above, the child lock can be designed to release the child lock through the child lock setting and the decryption key of the present invention and the image captured by the camera as described above.

As described above, in the present invention, even when child lock is set by encryption, children are released without permission by releasing child lock only when the face photographed using the camera and the registered parental control face coincide. Can be prevented.

Meanwhile, in the detailed description of the present invention, specific embodiments have been described, but various modifications are possible without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined not only by the scope of the following claims, but also by those equivalent to the scope of the claims.
