Description

Monitoring method for devices with electronic tags

technical field

The invention relates to a monitoring method for an electronic tag.

Background technique

An electronic tag is a memory with readable identification information. There are a variety of electronic devices (such as electronic wallets, electronic attendance cards, etc.) with electronic tags, which can realize functions such as user identification, account management, and remote control. Its wide application brings great convenience to people's lives, so often Become a coveted target for thieves. Once it is stolen, criminals can use the electronic tag to pretend to be the user's identity and steal the user's funds and secret information, causing the owner to suffer huge losses.

Contents of the invention

The purpose of the present invention is to provide a monitoring method for a device with an electronic label, so that the user information of the device will not be stolen after the device is lost.

In the monitoring method of the present invention, the device with the electronic label is provided with a monitor that can only communicate with it wirelessly within a certain distance, and the steps are as follows:

Searching step: the monitor sends a search signal to the device with the electronic label;

Detection steps: The device with the electronic tag receives the search signal, if the search signal is not received within the set time, the electronic tag is locked.

Since the device with the electronic tag and the monitor can only communicate wirelessly within a certain distance, if they are too far apart, they will lose contact. The user places the device with the electronic tag and the monitor at different positions within the effective communication distance, so that the device with the electronic tag receives the search signal sent by the monitor. Once the device with the electronic tag is lost and out of the effective communication range, the search signal cannot be received, so the electronic tag is locked immediately to make the electronic tag unusable and to ensure that the user information in it will not be stolen.

Detailed ways

Embodiment one

In this embodiment, the device with the electronic tag is a mobile phone, commonly known as a mobile phone. The mobile phone with the electronic tag can realize functions such as identity authentication, remote control, and account management. This is the prior art and will not be described in detail. As shown in Figure 1, the processing unit of the mobile phone is connected to the receiving module, and the processing unit is connected to the locking pin of the electronic tag through a locking circuit, and the processing unit can lock the electronic tag through the locking circuit.

Figure 2 shows the connection structure of the monitor. The processing unit is connected to the transmitting module, which can communicate wirelessly with the receiving module of the mobile phone within a range of 5 meters, and cannot communicate beyond the range of 5 meters.

See Figure 3 for the operation method. The user takes the mobile phone and the monitor at different positions on the body, and the distance between the mobile phone and the monitor is within 5 meters. The monitor sends out a search signal every 1 second by the transmitting module, and the processing unit of the mobile phone receives the signal through the receiving module every 5 seconds, then the search signal is received, and the electronic tag works normally.

Once the mobile phone is stolen, the processing unit of the mobile phone still receives signals through the receiving module every 5 seconds. However, the distance between the mobile phone and the monitor exceeds 5 meters, and the search signal cannot be received. At this time, the processing unit immediately sends a locking signal to the locking circuit , to lock the electronic tag, the information in the electronic tag cannot be read out, ensuring that the information will not be stolen.

If the user accidentally damages the monitor and the mobile phone cannot receive the signal from the monitor, the electronic tag will still be locked. At this time, the user can input the unlock password on the mobile phone keyboard, and the processing unit compares the input with the set password value, and if the password matches, it will be unlocked, and the electronic tag will not be locked again; after the monitor is repaired, the user Put the mobile phone and the monitor within 5 meters, the mobile phone will receive the search signal again, and the processing unit will be unlocked and resume the original operation.

In addition to the mobile phone, the device with the electronic tag can also be a bank card, time card, etc., and its processing unit can be provided by the device with the electronic tag or can be provided separately. The power supply of the monitor can be self-contained.

Embodiment two

In this embodiment, the device with the electronic tag is still a mobile phone. As shown in Figure 4, the processing unit of the mobile phone is connected with a transmitting module and a receiving module, and the electronic tag is connected to the processing unit through a locking circuit, and the processing unit can lock the electronic tag through the locking circuit.

Figure 5 shows the connection structure of the monitor. The processing unit is connected with a transmitting module and a receiving module, which can communicate wirelessly with the receiving module and transmitting module of the mobile phone within a range of 5 meters, and cannot communicate beyond the range of 5 meters. The processing unit is also connected with a buzzer as an alarm device.

The operation method is shown in Figure 6. The user takes the mobile phone and the monitor at different positions on the body, and the distance between the mobile phone and the monitor is within 5 meters. The processing unit of the mobile phone randomly generates a variable code, which is sent by the transmitting module, and the processing unit of the monitor receives the variable code through the receiving module every second. The processing unit of the mobile phone performs preset calculations on the variable codes, and the processing unit of the monitor also performs the same or corresponding setting calculations on the variable codes, and the transmitting module of the monitor sends the calculation results as a search signal. After sending the variable code, the processing unit of the mobile phone receives a signal through the receiving module every 5 seconds, and when it receives the search signal, the processing unit compares it with the calculation result of the machine, and if the two match, it will work normally.

Once the mobile phone is stolen, the processing unit of the monitor still receives a signal through the receiving module every 1 second, but the distance between it and the monitor exceeds 5 meters, and the variable code cannot be received, and the buzzer will immediately alarm. Similarly, the processing unit of the mobile phone still receives a signal through the receiving module every 5 seconds, but the distance between it and the monitor exceeds 5 meters and cannot receive the search signal. At this time, the processing unit immediately sends a locking signal to the locking circuit to lock Electronic tags, the information in the electronic tags cannot be read out, ensuring that the information will not be stolen. The processing unit can also lock other components such as the mobile phone keyboard, screen, SIM card, etc., and its locking method is a prior art. The processing unit can also make the mobile phone sound an alarm at the same time.

Even if the thief uses another monitor to try to generate the calculation result, because he cannot know the calculation method of the original monitor, it cannot correspond to the calculation result of the mobile phone. If the calculation results of the computer do not match, the electronic tag will still be locked, and thieves still cannot steal the information in the electronic tag. After the property is returned to the original owner, put the mobile phone and monitor within 5 meters, the mobile phone will receive the matching calculation result again, and the processing unit will be unlocked and resume the original operation.

The rest are the same as the examples.
