1 is a block diagram showing the configuration of a portable terminal according to an embodiment of the present invention.

Referring to FIG. 1, the wireless telephone number receiving unit 11 receives encrypted telephone number information through a wireless communication method.

The decoder 12 decodes the encrypted telephone number information received through the wireless telephone number receiver 11 under the control of the controller 15 to obtain actual telephone number information.

The voice call processor 13 attempts to make a call with the phone number information decoded by the decoder 12 under the control of the controller 15 and performs an operation of the voice call. Here, the voice call processor 13 generally refers to a module for voice call provided in a portable terminal.

The keypad 14 has keys for inputting numeric and text information and function keys for setting various functions. The keypad 12 also has function keys according to the standby management mode.

The controller 15 performs a function of controlling the overall operation of the portable terminal. In addition, the control unit 15 controls to attempt a call with the telephone number information obtained by decoding the encrypted telephone number information received through the wireless telephone number receiving unit 11. In addition, the control unit 15 decodes the encrypted telephone number information and displays a message called a privacy telephone number on the list of recently called numbers. In addition, the controller 15 controls the display unit 17 not to display the decoded telephone number.

The memory 16 stores a list of recently called numbers. In addition, the memory 16 stores the message of the privacy telephone number instead of the encrypted telephone number information in the list of recently called numbers under the control of the controller 15.

The display unit 17 displays messages generated during program execution under the control of the control unit 15. In addition, the display unit 17 displays a guide message indicating whether to make a telephone call to an encrypted telephone number under the control of the control unit 15.

Looking at the operation of the portable terminal with reference to FIG. 1, the controller 15, if wirelessly encrypted telephone number information is received through the wireless telephone number receiving unit 11, a guide message to call the encrypted telephone number? Is displayed on the display unit 17. Here, the wireless telephone number receiver 11 may be, for example, an RFID reader that decrypts an RFID tag according to a radio frequency identification (RFID) scheme. Here, the RFID tag may include a passive tag having no power and an active tag having a power source or a central processing unit (CPU). However, the passive RFID tag and the active RFID tag are almost identical in terms of the function of storing data or exchanging information. However, in the communication distance dimension, an active RFID tag is used for long distance transmission (3 m or more) and a passive RFID tag is used for short distance transmission (within 1 m).

Thereafter, the controller 15 attempts to connect the phone through the voice call processor 13 according to the key data generated by the key manipulation of the user's keypad 14 according to the guide message. In addition, the controller 15 prevents the actual telephone number corresponding to the encrypted telephone number information from being displayed on the display unit 17.

In the operation of the portable terminal 10 of the present invention described above, with reference to the accompanying drawings which take an example of the field applied in real life in order to help understanding as follows.

2 is an exemplary view for explaining an operation process of a portable terminal according to an embodiment of the present invention. 2 illustrates a situation in which a driver contact tag including a phone number information of an encrypted portable terminal is placed while parking, and a specific person tries to contact the portable terminal by using the contact information of the driver. The driver contact tag may be attached to a notice board on which a phrase indicating that the driver is busy.

Referring to FIG. 2, a user of the portable terminal 10 may wirelessly communicate between the portable terminal 10 and the driver contact tag in the vehicle 20 to contact the driver's phone number corresponding to the vehicle 20. Enter a certain distance area. Here, the wireless communication is a short-range wireless communication method, preferably in the present invention may be RFID. The radio telephone number receiver 11 then becomes an RFID reader and the driver contact tag becomes an RFID tag.

The portable terminal 10 wirelessly receives the telephone number information of the vehicle owner, which is encrypted and stored in the driver contact tag through the wireless telephone number receiver 11. Then, the controller 15 decodes the encrypted telephone number information received through the wireless telephone number receiver 11 (deleting the encrypted telephone number information: delete) through the decoder 12 to obtain actual telephone number information. .

After that, the control unit 15 obtains the actual telephone number and then "Would you like to connect?" Is displayed on the display unit 17. According to the user's selection, the control unit 15 attempts to connect to the actual phone number. In addition, the controller 15 does not store the actual telephone number information of the encrypted telephone number in the recent call number list. However, the controller 15 allows only the message of the privacy phone number to be stored in the list of the recently called number.

3 is a flowchart illustrating a call processing method of a portable terminal according to an embodiment of the present invention. 3 will be described under the assumption that it is the same situation as in FIG. 2 to help the understanding of the present invention.

Referring to FIG. 3, in step 301, a user of the portable terminal 10 accesses a vehicle or a driver contact tag in the vehicle to make contact with the driver of the vehicle 20.

Then, in step 303, the controller 15 wirelessly receives the driver's telephone number encrypted from the driver contact tag.

In operation 305, the controller 15 displays a guide message on the display unit 17 indicating whether the telephone number of the driver is to be encrypted. Thus, the user operates the keypad 14 of the portable terminal 10 to select whether or not the telephone connection to the encrypted telephone number.

Then, in step 307, the controller 15 determines whether the user wants to connect the phone according to the user's selection, and if so, performs the steps 309 to 311.

That is, in step 309, the controller 15 decodes the received telephone number encrypted by the wireless telephone number receiver 11 into actual telephone number information by the decoder 12.

Then, in step 311, the controller 15 controls the voice call processor 13 to attempt a phone call to the decoded real phone number. In this case, the actual driver's telephone number is not displayed on the display unit 17. In addition, the actual driver's phone number is not stored in the list of the recently called numbers. However, in order to leave only the ground that the telephone call was made, the message is stored and displayed as a privacy telephone number in the list of recently called numbers. In addition, the phone number information may be deleted after a predetermined time elapses after the call is connected or by a user's key operation.

On the other hand, by storing the encrypted phone number information in the message called the privacy telephone number, if the call is not connected at once, the information is re-sent using the information.

So far, the above-described process has been described as an example of the guide plate of the missed vehicle, but it is obvious that the technical concept may be used not only in the above-described guide plate of the missed vehicle but also in a business card to which a contact information should be described.

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 the equivalents of the claims.

As described in detail above, the present invention protects the privacy of the driver from an unspecified number by allowing wireless phone number information of an encrypted contact to be decoded and then attempting to contact the corresponding phone number by decoding the encrypted phone number information. It can work.

In addition, it is possible to attempt to automatically call to the telephone number received wirelessly so that the user can make a call without having to directly enter a numeric key corresponding to the telephone number, thereby increasing the convenience of the user.
