The heart is a pump that circulates blood throughout the body, and it contracts and expands regularly. The pumping action of the heart is achieved by contracting the myocardium. Every time the heart beats, weak electricity is generated, and electricity flows through the body due to the weak electricity. In addition, as shown in 410 of FIG. 4 , the electrocardiogram is a graph in which a potential difference between electrodes is recorded at an appropriate portion of the body surface by a current flowing in the body.

Referring to 420 of FIG. 4 , the short P wave is a wavelength indicating sequential depolarization of the right atrium and the left atrium. The QRS wave is a waveform representing the depolarization of the right ventricle and the left ventricle. The T wave is a waveform representing the repolarization of the ventricles.

Reference numeral 510 of FIG. 5A is an electrocardiogram obtained by the electronic device 110 , and reference numeral 520 of FIG. 5A is an electrocardiogram obtained by the terminal 120 . In order to successfully establish a wireless communication connection between the electronic device 110 and the terminal 120 , the first ECG information obtained from the electronic device 110 and the second ECG information obtained from the terminal 120 must match. The electronic device 110 compares the first ECG information and the second ECG information. The electronic device 110 may determine whether the values of all regions in each of the first electrocardiogram information and the second electrocardiogram information match each other, but may also determine whether they coincide with each other by comparing only a predetermined region or a predetermined value. Here, the first electrocardiogram information is currently acquired electrocardiogram information, not previously acquired electrocardiogram information. The electronic device 110 may have high accuracy because it compares the electrocardiogram based on the first electrocardiogram information and the second electrocardiogram information acquired at the same time.

Referring to FIG. 5A , it can be seen that the first region 511 of the first electrocardiogram and the first region 521 of the second electrocardiogram correspond to each other, and the information of the electrocardiogram coincides with each other. However, although the second region 512 of the first electrocardiogram and the second region 522 of the second electrocardiogram correspond to each other, it can be seen that the electrocardiogram information does not match with each other. Accordingly, the electronic device 110 does not perform pairing with the terminal 120 through a wireless network.

In general, fingerprint information is obtained by extracting the location and properties of a feature point composed of a bifurcation point, an end point, etc. of a fingerprint ridge. Since each user's fingerprint information has a unique characteristic, each user can be distinguished. The identification of fingerprint information may be performed through an algorithm that compares extracted attributes.

The electronic device 110 may acquire fingerprint information by utilizing the electrical conductivity characteristics of the skin based on a method using semiconductor technology. When the fingertip is directly in contact with the surface of the silicon chip, the fingerprint information can be obtained by reading the special shape of the fingerprint in contact with the chip surface as an electrical signal.

The electronic device 110 may convert a fingerprint having a characteristic unique to each user into a digital number, extract the characteristic, and acquire data. The image processing process of the fingerprint may be classified into smoothing, binarization, and thinning processes, but is not limited thereto. Smoothing is a method of increasing the contrast of a fingerprint and removing noise. Binarization is a method of converting an image of 256 gray-levels into “0” (black) or “1” (white). Thinning is a method of reducing the thickness of fingerprint lines to 1 pixel.

As shown in FIG. 6 , three characteristics may be obtained from fingerprint information obtained through thinning. The electronic device 110 may acquire at least one of the pattern information 610 of the fingerprint, the split information 620 of the fingerprint, and the feature point 630 of the fingerprint through an image processing process.

As a specific example, the preset time may be within 2 minutes from the point in time when the first fingerprint information is acquired. The first sub information may correspond to one of pattern information, split information, and feature point information of a fingerprint. Meanwhile, the electronic device 110 may transmit an advertisement packet including the first sub information of the first fingerprint information to the terminal 120 .

The terminal 120 acquires the user's second fingerprint information. Here, the second fingerprint information is acquired by the user in advance in the terminal 120 or by receiving the first sub-information of the first fingerprint information and directly touching the user's finger in the terminal 120 within a preset time. may be information.

When the first sub information is pattern information of a fingerprint, the terminal 120 compares the first sub information of the first fingerprint information with the first sub information of the second fingerprint information to confirm whether the pattern information of the fingerprint matches. If they do not match, the terminal 120 does not establish a wireless communication connection with the electronic device 110 . If they match, the terminal 120 transmits the second sub information of the second fingerprint information to the electronic device 110 . The second sub information may be information excluding the first sub information from fingerprint information. Specifically, the second sub information may be split information of a fingerprint. Meanwhile, the terminal 120 may transmit an advertisement packet including the second sub information of the second fingerprint information to the electronic device 110 .
