As shown in FIG. 3, the controller 800 may include a encryption setting module 810 for encrypting a phone number or a stored folder, an application, and data, and information received from a phone number for which a secret is set (for example, a call, Encryption module 820, which encrypts a text, etc.), or a folder, an application, and a data related icon so as not to be displayed on the display unit 510, A reception notification module 830 that notifies the user of the contents received from the telephone number through a voice, vibration, or haptic module, etc., and displays a secret reception mark, a secret folder, an application, and data according to a specific input by the user. The decryption module 840 displayed on the unit 510 is provided.

In addition, the present invention is not limited thereto, and includes a call hold module 850 for performing a call hold function and a recovery function, and a call reject module 860 for rejecting reception of some communication functions at a specific time or space according to a user's setting. It may further include.

Through this, the portable terminal of the present embodiment does not display the contents related to the reception of the call when the call comes from the designated phone number, and informs the user in a different way (ie, voice or vibration). This display can protect the privacy information exposed by the spring.

First, the secret setting module 810 manages the secret setting of at least one phone number or folder, application, and stored data among the stored phone numbers.

The secret setting module 810 may be shown to the user as a separate setting screen. This allows the user to easily set up information or functions for secrecy. In addition, the encryption setting module 810 may be displayed on the screen by the encryption unlocking module 840.

The phone number or folder, application, and stored data set and encrypted by the encryption setting module 810 is encrypted by the encryption module 820 to store the phone number, folder, application, and stored data. All actions associated with are not shown on the display.

For example, when a call is received from the secreted phone number, the reception is not displayed on the display unit 510 by the secreting module. That is, the display 510 does not display the contents of the call from the corresponding phone number. In addition, the text coming from the telephone number is not directly displayed on the display unit 510. In this case, the reception notification module 830 informs the user that a call has been made by voice or vibration. That is, the phone rings or vibrates without any indication on the screen. In this case, the call hold function may be performed by the call hold module 850 according to a user setting.

In addition, if a user puts an icon of a call related function in a secret folder, the call related function is not displayed on the screen of the display unit 510. In addition, in the case of the encryption module 820, call-related functions, folders, and applications controlled by the encryption module 820 block the actions displayed on the display unit 510 for privacy.

In addition, when a user creates a secret folder through the encryption module 820 and stores a media file such as a picture or a video in the secret folder, the media files are not displayed on the screen. In addition, when storing a social networking program (messenger program such as KakaoTalk) in this secret folder, when the information of the program is imported from the outside, it is not displayed on the screen. In addition, the designated number communication, that is, the contents of the conversation and text reception can be executed or automatically saved in the secret folder. In addition, the voice call record may be implemented in the secret folder according to the user's setting the designated number or the entire number.

The reception processing method through the encryption module 820 is as follows.

First, when a call comes from a sender, the caller's telephone number is searched to determine whether the telephone number is a secret telephone number. After that, if the secret number is not displayed on the screen, it is displayed by voice or vibration. In addition, if the call rejected number, the call is rejected. If the call is on hold, the call is blocked.

The reception notification module 830 transmits the contents received from the user to the voice, vibration, or haptic module when the function encrypted by the encryption module 820 is executed (if information is input from the outside). Notify the user by the same extra means. At this time, the reception alarm module may also enable a vibration / silence mode so that an outsider, not the user, may not know the reception status.

When the deciphering module 840 receives a specific input from the user, the deciphering module 840 displays the information or program secreted by the deciphering module 820 on the display unit 510.

For example, when a user inputs a designated password, the secret of information or a program that is secreted by the decryption module 840 is temporarily released and displayed on the display unit 510.

The encrypted folder or information is not displayed at all on the screen of the display unit 510 by the encryption module 820. Therefore, in the present embodiment, the decryption module 840 operates when the user provides an input by a specific operation.

In other words, existing devices display a locked folder or icon on the screen, and when the folder or icon is clicked, the device unlocks the lock after recognizing a separate password or pattern. However, since the information (program, icon, encryption folder, etc.) encrypted by the encryption module 820 of the present embodiment is not displayed at all on the display unit 510, it cannot be clicked or displayed. Therefore, input by a specific operation is performed.

There may be various methods for such an input, but in the present embodiment, first, when the user clicks the same point on the screen of the display unit 510 three to ten times in a row, the decryption module 840 operates. When the decryption module 840 is operated, a separate password input may be required or a pattern input may be required. In addition, the de-secret module 840 may operate by drawing a predetermined pattern on the screen. At this time, the predetermined pattern may be input twice in succession. In addition, the decryption module 840 may operate through the fingerprint input. In addition, the secret release module 840 may be operated through a voice input. In addition, the screen may operate the decryption module 840 by simultaneously touching several points. Alternatively, when the specific area is pressed for a predetermined time (5 seconds to 20 seconds) or more, the decryption module 840 may operate. Of course, the above description focuses on the case in which the touch display is used as the display unit 510. However, when using a general display, the decryption module 840 may be activated using an input means, that is, an input by a keypad.

In addition, the controller 800 of the present embodiment further includes a reception rejection module 860. Through this, it is possible to refuse to perform some functions while the portable terminal is located at a specific time or area (space) according to the user's setting. For example, from 10 pm to 7 am, some communication functions may be rejected, or if you are located in a meeting place or classroom via GPS signals, you may be able to suppress communication as well as full program behavior. This is performed by preventing all the functions from being displayed on the screen of the display unit 510 as described above.

It is also possible to hold a call through the call hold module 850. Of course, the call can be notified through a separate comment, or the call can be notified by sending SMS.

In addition, the portable terminal of the present embodiment may always enable a call to the number through the registration of the required telephone number in case of loss.

In the above description, the module has been described according to its function and characteristics. However, the portable terminal having the privacy protection function of the present embodiment is not limited thereto, and various functions may be separately operated. That is, reception processing, situation management, folder management, system management and call hold management are possible.

For example, reception security can be started, reception security released, and secure phone book control can be performed for reception processing. That is, in the case of reception security start, reception security is activated, cognitive security is activated, and LOG movement is started. Receive processing is performed through the start of receive security. And, in the case of reception security release, reception security is stopped and cognitive security is stopped. In addition, in the case of a secure phone book, it is possible to inquire, modify, delete and add a secure phone book. Therefore, the above-described encryption setting module may proceed with setting up and adding a secure phone book, starting reception security by the encryption module, and receiving security by the decryption module.

In addition, limited situation management and situation variable editing are available for situation management. Limited situation management is available for retrieval management set inquiry, modification, deletion and addition. In the case of editing situation variables, you can search, modify, delete and add situation variables.

In the case of folder management, file management, LOG management, and program execution are possible. File management allows you to search, move and delete files, and LOG management allows you to search and delete call logs through LOG inquiry and deletion. Program execution can be done by hidden program.

In addition, the system management can set the app display operation, cognitive security settings. The app display action setting can be activated, canceled, saved action, and gesture recognition test. Cognitive security settings can be activated, canceled, saved and tested.

In addition, call hold management is possible to hold a call and recover a held call. Hold call recovery is available for call recovery, hold conference inquiry and selection.

Processing and management as described above may be performed in the module of the controller 800 described above.
