Based on the above-mentioned terminal hardware structure and communication network system, various embodiments of the mobile payment method of the present invention are presented.

The invention further provides a bracelet unlocking method, and referring to fig. 3, fig. 3 is a flow chart of a first embodiment of the bracelet unlocking method.

In this embodiment, the method for unlocking the bracelet is applied to an intelligent bracelet provided with NFC (Near Field Communication, near field communication technology), the intelligent bracelet is bound with a mobile terminal before use, and one intelligent bracelet corresponds to only one mobile terminal.

The bracelet unlocking method comprises the following steps:

step S10, detecting the relative distance between the mobile terminal and the intelligent bracelet when the intelligent bracelet is in a screen locking state;

in this embodiment, the smart bracelet is a wearable smart device, through which a user can record real-time data such as exercise, sleep, diet, etc. in daily life, and synchronize these data with a mobile phone, a tablet, etc., and play a role in guiding healthy life through the data. When the intelligent bracelet is free of any operation in a preset time, automatic screen locking can be performed, data safety of the intelligent bracelet is protected, misoperation of the bracelet is prevented, and power consumption of the bracelet is saved.

Further, the NFC module is arranged on the intelligent bracelet, the mobile terminal bound with the intelligent bracelet also supports the NFC function, NFC is a short-distance high-frequency wireless communication technology, non-contact point-to-point data transmission is allowed between electronic devices, and NFC is generally used for safe communication within 10cm in a short distance, so that when the intelligent bracelet is in a screen locking state, the intelligent bracelet regularly detects the relative distance between the mobile terminal and the intelligent bracelet, and the NFC function is started only when the relative distance meets certain conditions, so that data interaction between the mobile terminal and the intelligent bracelet is realized.

Step S20, when the relative distance is smaller than or equal to the preset distance, acquiring a mobile phone serial number corresponding to the mobile terminal and an NFC label corresponding to the intelligent bracelet;

in this embodiment, when the smart bracelet is sufficiently close to the mobile terminal, the smart bracelet and the mobile terminal may start the NFC function to implement data interaction between them when the smart bracelet detects that the relative distance between the smart bracelet and the mobile terminal is less than or equal to the preset distance, where the preset distance may be set according to the actual situation, and the preset distance is generally less than 10cm, because exceeding 10cm does not generally support NFC communication.

Specifically, when the relative distance between the smart bracelet and the mobile terminal is smaller than or equal to the preset distance, the smart bracelet can acquire the mobile phone serial number of the mobile terminal through the NFC module, meanwhile acquire the NFC label corresponding to the smart bracelet, and the smart bracelet is bound with the mobile terminal before use, namely, the corresponding relation between the mobile phone serial number and the NFC label is saved, wherein the mobile phone serial number is commonly called IMEI code, is an electronic serial number composed of 15 digits, corresponds to each mobile terminal one by one, and is unique worldwide.

Step S30, determining whether the NFC tag meets a preset condition or not based on the mobile phone serial number;

in this embodiment, each mobile terminal has a unique mobile phone serial number, and the serial numbers are unique worldwide, so that the mobile terminal and the smart band can bind the mobile terminal and the smart band through the corresponding relationship between the mobile phone serial numbers and the NFC tag, that is, the NFC tag of one smart band only corresponds to the mobile phone serial number of one mobile terminal, and the corresponding relationship is stored in the preset storage area of the smart band.

Further, step S30 includes:

step S31, determining whether a corresponding relationship between the mobile phone serial number and the NFC tag exists in a preset storage area, where when the corresponding relationship exists in the preset storage area, the mobile phone serial number and the NFC tag meet a preset condition.

In this embodiment, if the smart band is bound with the mobile terminal before use and the binding is successful, the corresponding relationship between the mobile phone serial number corresponding to the mobile terminal and the NFC tag corresponding to the smart band is stored in the preset storage area of the smart band.

Specifically, after the smart bracelet obtains the mobile phone serial number corresponding to the mobile terminal and the NFC label corresponding to the smart bracelet, inquiring is carried out in a preset storage area of the smart bracelet, and if the corresponding relation between the mobile phone serial number and the NFC label exists in the preset storage area, the mobile phone serial number and the NFC label are judged to meet the preset condition.

Step S40, when the NFC tag meets a preset condition, a first swing direction of the intelligent bracelet is obtained;

in this embodiment, when the mobile phone serial number and the NFC tag meet preset conditions, the smart bracelet is further unlocked by using the swing direction of the smart bracelet. Because the intelligent bracelet is provided with the acceleration sensor, the sensor can calculate the inclination angle of the intelligent bracelet relative to the horizontal plane, and the moving direction of the intelligent bracelet can be analyzed through the inclination angle.

Further, step S40 includes:

step S41, when the NFC tag meets a preset condition, prompting a user to throw a bracelet;

In this embodiment, when the mobile phone serial number and the NFC tag meet the preset condition, the smart bracelet outputs a prompt message to prompt the user to shake the bracelet to perform the bracelet decoding operation. It should be noted that, each time the bracelet is flicked, the bracelet may correspond to a password, if there are N passwords, the bracelet is required to be flicked N times, and each time the bracelet is flicked, the prompt information is believed to be more, alternatively, the prompt information may include: the total number of flicks, what number of flicks is currently, and the like.

Step S42, when the swinging bracelet operation is detected within the first preset time, acquiring a first swinging direction of the intelligent bracelet corresponding to the swinging bracelet operation based on the acceleration sensor.

In this embodiment, after the prompt information is displayed on the smart bracelet screen, the operation of swinging the smart bracelet needs to be performed within a preset time, the acceleration sensor of the smart bracelet obtains the swinging direction of the smart bracelet by detecting the swinging operation of the smart bracelet, and then the smart bracelet performs the password unlocking operation according to the swinging direction.

And step S50, controlling the intelligent bracelet to be unlocked based on the first swing direction and a preset password.

In this embodiment, after the smart bracelet obtains the flick direction of the bracelet, the flick direction is converted into a corresponding character according to a preset rule, then the character is used as input to be compared with a preset password, when the input character is completely matched with the preset password, the password is correct, the smart bracelet is successfully unlocked, and the smart bracelet can work normally and interact data with the mobile terminal.

Further, in the first embodiment, step S42 further includes: and outputting prompt information of password unlocking errors when the swinging bracelet operation is not detected within the first preset time.

In this embodiment, after the prompt information is displayed on the smart bracelet screen, the operation of swinging the bracelet needs to be executed within the preset time, and when the preset time is exceeded, the smart bracelet does not detect any operation of swinging the bracelet, then the decoding of the bracelet is considered to be failed, and the prompt information of password unlocking errors is output. It should be noted that if there are N-bit passwords, the bracelet is required to swing N times, and each time, the bracelet is required to swing within a preset time.

According to the bracelet unlocking method, when the intelligent bracelet is in a screen locking state, the relative distance between the mobile terminal and the intelligent bracelet is detected, then when the relative distance is smaller than or equal to a preset distance, a mobile phone serial number corresponding to the mobile terminal and an NFC label corresponding to the intelligent bracelet are obtained, whether the NFC label meets preset conditions or not is determined based on the mobile phone serial number, then when the NFC label meets the preset conditions, a first swing direction of the intelligent bracelet is obtained, and finally unlocking of the intelligent bracelet is controlled based on the first swing direction and a preset password. In the process of unlocking the intelligent bracelet, after NFC authorization is passed, an unlocking password is further determined according to the direction of the flicking bracelet, so that the error unlocking of the bracelet is avoided, meanwhile, the difficulty of the password is effectively increased, and the safety of unlocking the bracelet is improved.

Based on the first embodiment, a second embodiment of the screen processing method of the present invention is proposed, referring to fig. 4, in this embodiment, before step S10, further includes:

step S60, detecting the swinging times of the second swinging direction corresponding to the intelligent bracelet in a preset time after the current moment when the password setting command is detected;

in this embodiment, the smart band needs to set a password in advance, and when the smart band detects a password setting instruction, the smart band starts to set the password, and uses the flick direction as input of the password setting.

Further, in order to ensure higher security, the password is usually at least 6 bits, so the number of times to flick the bracelet is determined according to the number of bits of the password, that is, the password has 6 bits, the bracelet is flicked 6 times, the password has 8 bits, and the bracelet is flicked 8 times.

It should be noted that, the password setting needs to be completed within a preset time, that is, the input of all passwords is completed within the preset time, for example, the preset time is 30 seconds, the password is 6 bits, and the operation of swinging the bracelet for 6 times is completed within 30 seconds; alternatively, during the password setting process, the time interval of every two-bit password input cannot exceed a certain interval, for example, the time interval of every two-bit password input is required to be 10 seconds, that is, the operation of throwing the bracelet must be completed within 10 seconds from the execution of the password setting command.

Step S70, generating a preset password based on the second swing direction of the preset times and the azimuth comparison table.

In this embodiment, the azimuth comparison table is a comparison relation between the flick direction of the bracelet and the characters, alternatively, 8 directions, that is, east, south, west, north, southeast, southwest, northeast, northwest, each corresponding to a number, letter, coincidence, etc., may be set for the flick direction of the bracelet, and when the smart bracelet detects the flick direction of the bracelet, the flick direction is converted into the corresponding characters according to the content of the comparison table, so as to generate the preset password.

For example, the azimuth lookup table includes 2 columns of contents, one column is the hand ring flick direction, and the other column is the character, as shown in table 1, 8 directions: the numbers 1-8 are corresponding to the east, south, west, north, southeast, southwest, northeast and northwest, respectively, and letters or other symbols can also be corresponding to the letters or other symbols.

TABLE 1

Further, in the first embodiment, step S60 further includes:

step S80, when a command for setting an azimuth comparison table is detected, setting parameters corresponding to the command for setting the azimuth comparison table are obtained;

and step S90, updating a corresponding azimuth comparison table of the intelligent bracelet based on the setting parameters.

In this embodiment, when a command for setting the azimuth comparison table is detected, parameter setting may be performed on the azimuth comparison table, where the azimuth comparison table includes an azimuth and a character corresponding to the azimuth, and preferentially, the azimuth is already set by factory, no modification is supported for a user, and the user only needs to set the character, and may set numbers, letters, symbols, and the like according to a specific actual situation.
