The modulated cryptographic signal can be demodulated by the demodulation unit 165 of the mobile type mobile terminal 100.

A frequency shift keying (FSK) scheme can be used for modulation and demodulation of an encryption signal.

The frequency shift keying is a type of frequency modulation (FM) in a broad sense, and is a modulation method used when transmitting a digital signal through an analog transmission path. Binary numbers 1 and 0 can be associated with two frequencies, that is, a high frequency f1 and a low frequency f0. That is, two frequencies f1 and f0 are assigned to the signals of 1 and 0, respectively. As described above, since it uses two states of high frequency (f1) and low frequency (f0), it is resistant to noise. Each of the high frequency f1 and the low frequency f0 can be used in the range of 120 Hz to 160 Hz. For example, 120 Hz is used as the low frequency f0 and 160 Hz as the high frequency f1. Such a range of 120 Hz to 160 Hz does not overlap with the frequency of other living-body signals existing in the human body or generated, and it does not have a feeling of distraction. Therefore, this frequency range is a frequency shift for modulating and demodulating the crypto- Modulation (FSK: Frequency Shift Keying) method.

For example, when the password is 1234, such a password is 10011010010 as shown in Fig. 4 as a digital signal.

The watch-type mobile terminal 200 can be modulated with an encryption signal as shown in FIG. 4B using a frequency shift keying scheme. That is, 1 can be modulated at a high frequency and 0 can be modulated at a low frequency.

The demodulating unit 165 may be electrically connected to a conductive terminal exposed to the outside. The conductive terminal may be in contact with the user's body. Specifically, the conductive terminals may be in contact with the user's hand or fingers, but the present invention is not limited thereto.

The watch-type mobile terminal 200 may include a conductive terminal 206 mounted on the rear surface of the watch-type mobile terminal 200 as shown in FIG. 3B.

The conductive terminal 206 may be formed of a conductive material such as a metal. The rear cover 204 may be installed on the rear surface of the watch-type mobile terminal 200. In this case, the conductive terminal 206 can be fixed by the back cover 204. [

The conductive terminals 206 may be disposed in one area of the rear cover 204. For example, the conductive terminals 206 may be disposed in the central region of the rear cover 204, but the present invention is not limited thereto.

If the rear cover 204 is formed of a metal material and has the function of the conductive terminal 206, the conductive terminal 206 need not be separately provided. In this case, the rear cover 204 may be the conductive terminal 206. [

When the watch-type mobile terminal 200 is worn on the wearer's wrist, the conductive terminal 206 or the rear cover 204 may be in contact with the user's wrist.

Accordingly, the conductive terminals of the mobile type mobile terminal 100, that is, the back cover 103 and the conductive terminals 206 of the watch type mobile terminal 200 come into contact with the user's body. In this case, a human body is a conductive line for transmitting a signal, and is a conductive line for transmitting and receiving data, for example, an encryption signal, between the watch type mobile terminal 200 and the mobile type mobile terminal 100 using human body communication by the user's body This is possible. That is, the encryption signal generated in the watch-type mobile terminal 200 can be transmitted to the mobile-type mobile terminal 100 through the user's body.

On the other hand, the unexplained reference numeral 202 is a band, which serves to fix the watch-type mobile terminal 200 to the user's wrist when worn on the wearer's wrist.
