technical field

The invention relates to the field of terminal control, in particular to a method and system for identifying and controlling equipment by using the fingerprint of a mobile terminal.

Background technique

With the wide application of information technology in people's daily life, its related technologies are gradually becoming mature. For example, in the field of smart home appliances, users can use mobile terminals to control various home appliances, and use short-distance communication or long-distance communication to realize home or remote control. For another example, in the field of car control, users can use mobile terminals to lock or unlock car doors. The function of using the mobile terminal to control other devices is convenient for users. However, while such a method provides more convenience for users, it also causes some security risks. If the user's mobile terminal is lost or falls into other people's hands, the user's car and home appliances may also be stolen, causing losses and inconvenience to the user. Therefore, it is very necessary to do some security settings on the mobile terminal.

The security function of a traditional mobile terminal is nothing more than setting software functions such as keyboard lock on the mobile terminal, and realizing security by inputting a password. When realizing secrecy by inputting a password, it is troublesome to input the password every time. Moreover, the password of the mobile terminal is easy to be cracked, resulting in the failure of the security function. Therefore, after cracking the password, the non-user can directly use the user's mobile terminal to control the user's car, home appliances, etc., thereby causing unnecessary losses to the user.

That is, these functional entities may be implemented in software, or in one or more integrated circuits, or in different network and/or processor means and/or microcontroller means.

FIG. 1 shows a flowchart of a method for controlling a device through a mobile terminal in the present invention. Figure 1 shows a total of 4 steps:

In step S101, the mobile terminal collects fingerprint information of the user, encrypts the fingerprint information to form first encrypted information, and sends it to the device.

The user's fingerprint can be collected by swiping or pressing, and through various methods, the fingerprint can be converted into a signal and input into the mobile terminal to further generate a fingerprint image. According to the fingerprint image, the fingerprint feature can be extracted as fingerprint information for subsequent Encryption and comparison operations. Preferably, the present invention adopts a capacitive method to convert fingerprints into signals. Specifically, when a fingertip scratches or presses a capacitive sensor that senses a fingerprint, the capacitive sensor generates a fingerprint image according to changes in capacitive signals generated by the fingerprint ridges and valleys of the fingerprint.

At this time, the acquired fingerprint image is a grayscale image containing more noise. Therefore, it is also necessary to preprocess the fingerprint image to improve the quality of the fingerprint image, enhance the contrast of fingerprint ridges and fingerprint valleys, and turn it into a clear point-line map for feature extraction. Preprocessing of fingerprint images includes normalization, image segmentation, enhancement, binarization and thinning. Corresponding preprocessing steps can be selected according to different application scenarios, which will not be described in detail here.

Feature extraction is performed on the preprocessed fingerprint image, and the extracted features and the corresponding position of each feature are used as fingerprint information. The first encryption algorithm of the fingerprint information may be one of RSA, AES, and DES, but is not limited thereto.

In step S102, the device encrypts the first encrypted information for a second time to form second encrypted information.

Wherein, the second encryption algorithm may be the same as the first encryption algorithm, or may be an encryption algorithm different from the first encryption algorithm.

In step S103, the device compares the second encrypted information with a comparison information, and the comparison information is obtained from an original fingerprint information through secondary encryption.

Wherein, the user's original fingerprint is collected by swiping or pressing, and a fingerprint image is generated, and fingerprint features are further extracted according to the fingerprint image as original fingerprint information for subsequent encryption operations.

The comparison information is obtained from the original fingerprint information through the first encryption algorithm and the second encryption algorithm. The two encryption algorithms here are the same as the above two encryption algorithms of the fingerprint information to be compared.

In a variation, the device compares the second encrypted information with the comparison information through a background server. That is to say, the device sends the second encrypted information to the background server for comparison with the comparison information stored in the background server.

Step S104, if the second encrypted information is consistent with the comparison information, the device executes an instruction.

If the second encrypted information is consistent with the comparison information, that is, the newly collected fingerprint information is consistent with the original fingerprint information, and the user who intends to operate the mobile terminal at this time is the user who input the original fingerprint. The user passes fingerprint verification, and the device executes an instruction. The instruction can be pre-stored in the device, or can be selected or edited and sent via the mobile terminal. Specifically, if the instruction is single, the instruction is preferably pre-stored in the device; if the instruction is more varied and complex, the instruction is sent by the mobile terminal.

Specifically, before step S101, the mobile terminal establishes a wireless connection with the device for communication, and the wireless connection mode includes Bluetooth, infrared, local area network, Internet or radio frequency. Different wireless connection modes are applicable to different application scenarios, and details are not repeated here.

The second encryption device 33 encrypts the first encrypted information received by the first receiving device 31 to generate second encrypted information. Here, the encryption algorithm for the second encryption may be the same as the encryption algorithm for the first encryption. The comparison device 35 compares the second encrypted information encrypted by the second encryption device 33 with a comparison information.

Example 1

Referring to FIG. 4 and FIG. 5 , when the device is a home appliance, the method for the mobile terminal to control the home appliance through fingerprint identification will be described.

Fig. 4 shows a topological diagram of a system for controlling home appliances through a mobile terminal according to an embodiment of the present invention. The mobile terminal 1 and the home appliances 5a, 5b access the Internet through their built-in Internet access devices respectively. Preferably, the user can choose to control the home appliance 5a, control the home appliance 5b or control the home appliances 5a and 5b simultaneously through the mobile terminal 1 . Taking the user's choice of controlling the home appliance 5a as an example, the mobile terminal 1 establishes a communication connection with the home appliance 5a, and the information or data transmitted thereafter follows the HTTP protocol. The mobile terminal 1 collects the user's fingerprint information, encrypts the fingerprint information for the first time, and then transmits it to the home appliance 5a. The household appliance 5a receives the fingerprint information encrypted for the first time, and encrypts the fingerprint information for the second time. The household appliance 5a compares the fingerprint information encrypted for the second time with the original fingerprint information also encrypted twice. If the comparison between the fingerprint information and the original fingerprint information is successful, the home appliance 5a sends a feedback comparison success message to the mobile terminal 1, indicating that the mobile terminal 1 can send an instruction to the home appliance 5a so that the home appliance 5a executes the instruction. For example, the mobile terminal 1 may send instructions such as turning on, turning off, and feeding back status information to the home appliance 5a. Specifically, when the home appliance 5a is an air conditioner, the user can turn on the air conditioner at home on the road through fingerprint recognition on the mobile terminal 1 . The home appliance 5a may also be other household electronic devices such as lamps and televisions. If the comparison between the fingerprint information and the original fingerprint information fails, the home appliance 5a feeds back the comparison failure information to the mobile terminal 1, and instructs the mobile terminal 1 to perform fingerprint collection again or give up controlling the home appliance 5a.

Fig. 5 shows a topology diagram of another system for controlling home appliances through a mobile terminal according to an embodiment of the present invention. The mobile terminal 1 and the home appliance intelligent management system 7 respectively access the Internet through their built-in Internet access devices. The home appliance intelligent management system 7 is in the same local area network as the home appliances 5a and 5b. Preferably, the user can communicate with the home appliance intelligent management system 7 through the mobile terminal 1 to control the home appliances 5a and 5b. First, the mobile terminal 1 establishes a communication connection with the home appliance intelligent management system 7 . The mobile terminal 1 collects the user's fingerprint information, encrypts the fingerprint information for the first time, and then transmits it to the home appliance intelligent management system 7 . The home appliance intelligent management system 7 receives the fingerprint information encrypted for the first time, and encrypts the fingerprint information for the second time. The home appliance intelligent management system 7 compares the fingerprint information encrypted for the second time with the original fingerprint information encrypted twice.

If the comparison between the fingerprint information and the original fingerprint information is successful, the smart home appliance management system 7 sends a feedback comparison success message to the mobile terminal 1, indicating that the mobile terminal 1 can send instructions to the home appliance 5a or 5b through the home appliance smart management system 7 so that the home appliance 5a or 5b executes the instruction. For example, the home appliance intelligent management system 7 feeds back controllable home appliances and executable instructions to the mobile terminal 1 . Specifically, the home appliance 5a is an air conditioner, and the home appliance 5b is a TV, and the home appliance intelligent management system 7 first feeds back that the controllable home appliances include air conditioners and TVs. The user can choose to control the air conditioner or the TV through the mobile terminal 1 . If the mobile terminal 1 chooses to control the air conditioner, the home appliance intelligent management system 7 further feeds back executable instructions to the system terminal, including opening, closing, setting mode, setting temperature and timer switch. The user can send an instruction to the home appliance intelligent management system 7 according to the requirement, and the home appliance intelligent management system 7 controls the air conditioner in the same local area network to execute the instruction according to the received instruction.

If the comparison between the fingerprint information and the original fingerprint information fails, the home appliance 5a feeds back the comparison failure information to the mobile terminal 1, and instructs the mobile terminal 1 to perform fingerprint collection again or give up controlling the home appliance 5a.

Example 2

An embodiment in which a user controls a car by performing fingerprint identification on a mobile terminal will be described below. Specifically, the car has a car control system.

Generally speaking, to control the vehicle control system (for example, to control the locking and unlocking of the vehicle doors), the user will control the vehicle control system at a place closer to the vehicle. Therefore, at this time, the mobile terminal can communicate with the vehicle control system through short-distance communication methods such as Bluetooth, infrared, and radio frequency. After the mobile terminal establishes a communication connection with the vehicle control system, the mobile terminal collects user fingerprint information, encrypts the fingerprint information for the first time, and then transmits it to the vehicle control system. The vehicle control system receives the fingerprint information encrypted for the first time, and encrypts the fingerprint information for the second time. The vehicle control system compares the fingerprint information encrypted for the second time with the original fingerprint information encrypted twice.

If the comparison between the fingerprint information and the original fingerprint information is successful, the vehicle control system directly executes the command pre-stored in the vehicle control system, that is, locks or unlocks the vehicle door. Specifically, if the vehicle control system detects that the vehicle door is in a locked state, an unlock command is executed; if the vehicle control system detects that the vehicle door is in an unlocked state, then a lock command is performed.

In a variation example, if the comparison between the fingerprint information and the original fingerprint information is successful, the vehicle control system can also send a feedback of successful comparison information to the mobile terminal, indicating that the mobile terminal can send an instruction through the vehicle control system so that the vehicle can execute the instruction. For example, the mobile terminal sends a start command to the car control system, and the car control system controls the start of the car. For another example, when the user parks the car in the parking lot and cannot find the car because the parking lot is too large, he can send instructions to the car control system through the mobile terminal, instructing him to return to the direction of the car, or instructing him to sound his horn so that the user can get back as soon as possible. Find its car. Specifically, the orientation of the car can be represented by the name of the parking space where the car is located (for example, A32, the 32nd parking space in Area A), or by a specific direction and distance (for example, 400 meters due east), or by a specific The image including the location of the mobile terminal and the car is not limited thereto.

If the comparison between the fingerprint information and the original fingerprint information fails, the car control system will feed back the comparison failure information to the mobile terminal, instructing the mobile terminal to re-collect the fingerprint or give up controlling the car.
