Example 1
FIG. 1 illustrates a flow chart of a blockchain-based information tracking method in accordance with an embodiment of the present application. As shown in fig. 1, the method may be applied to an internet of things platform, such as a server, and the method may include:
For example, the information tracking request may be a request for instructing the internet of things platform to track motion information of an object to be tracked. The information tracking request may include identification information of the data acquisition device, for example: an ID of the data acquisition device. The data acquisition device may be a device for acquiring motion information of an object to be tracked. For example, the object to be tracked is a poultry, and the poultry may carry a data acquisition device, where the data acquisition device may acquire motion data of the poultry in real time, and may analyze the motion data to obtain motion information of the poultry, for example: the acceleration information of the poultry is acquired, the acceleration of the poultry is maximum when the poultry lifts feet, the data acquisition equipment can draw a map according to the acceleration information of the poultry, every two peaks in the map can be recorded as one step, and then the step number information of the poultry is obtained.
The data acquisition device may store the acquired motion information of the object to be tracked into a blockchain, where the motion information stored into the blockchain is the first motion information. For example, the data acquisition device may directly store the motion information of the object to be tracked into the blockchain, or the data acquisition device may store the motion information of the object to be tracked into the blockchain through the internet of things platform. And the internet of things platform can acquire the first motion information of the object to be tracked, which is acquired by the data acquisition equipment, from the blockchain according to the identification information of the data acquisition equipment.
FIG. 2 illustrates a flow chart of a blockchain-based information tracking method in accordance with an embodiment of the present application.

For example, the data acquisition device may send the first motion information of the object to be tracked to the internet of things platform, and store the first motion information of the object to be tracked into the blockchain through the internet of things platform. After the internet of things platform stores the first motion information into the blockchain, the internet of things platform can obtain a block identification token of a block in the blockchain for storing the first motion information. Or the data acquisition device can directly store the first motion information of the object to be tracked into the blockchain, and can obtain a block identification token of a block in the blockchain for storing the first motion information, and the data acquisition device can send the block identification token to the internet of things platform.
After the internet of things platform obtains the block identification token, an association relationship between the block identification token and the identification information of the data acquisition equipment can be established. After the internet of things platform receives the information tracking request, the block identification token associated with the identification information of the data acquisition equipment carried in the information tracking request can be obtained according to the association relation.
After the block identification token associated with the data acquisition equipment is acquired by the internet of things platform, first motion information, namely the motion information of the object to be tracked acquired by the data acquisition equipment, can be acquired from the block identified by the block identification token in the block chain.
It should be noted that the blocks for storing the motion information of the object to be tracked corresponding to different times may be multiple, and correspondingly, the block identification token associated with the identification information of the data acquisition device may be multiple, and further, the first motion information of the object to be tracked, obtained by the internet of things platform according to the block identification token, may include the motion information of the object to be tracked corresponding to the multiple different times.
And step 103, generating a tracking result according to the first motion information of the object to be tracked.

In one possible implementation manner, the method may further include: and sending the tracking result to target equipment, wherein the target equipment is equipment for sending the information tracking request.
For example, when there is a tracking requirement for information related to an object to be tracked, a user may send an information tracking request to the internet of things platform through a device such as a terminal, where the information tracking request may include identification information of a data acquisition device carried by the object to be tracked. After the internet of things device obtains the first motion information of the object to be tracked from the blockchain according to the identification information of the data acquisition device, a tracking result (for example, the tracking result may include the first motion information) may be generated according to the first motion information, and the tracking result is sent to the user terminal, so that the terminal may display the tracking result to the user.
In this way, after receiving the information tracking request, the internet of things platform can acquire first motion information of the object to be tracked from the blockchain according to the identification information of the data acquisition device carried in the information tracking request, and can generate a tracking result according to the first motion information, so that a user can track the motion information of the object to be tracked through the tracking result. According to the information tracking method based on the blockchain, information tracking of the object to be tracked by the user can be achieved, and as the first motion information of the object to be tracked is stored in the blockchain, the first motion information of the object to be tracked is guaranteed to be not tampered, and accuracy and effectiveness of a tracking result can be guaranteed.
In one possible implementation manner, the data acquisition device is a detaching and destroying device carried by the object to be tracked.
In the application, the data acquisition equipment can be carried on the body of the object to be tracked and is used for acquiring the motion information of the object to be tracked, and once the data acquisition equipment is removed from the object to be tracked, the data acquisition equipment stops working immediately and cannot recover any more.
In this way, the first motion information stored in the blockchain can be ensured to be the motion information of the object to be tracked, which is acquired by the data acquisition equipment, and the possibility of information falsification can be reduced.
In one possible implementation manner, the information tracking request information is information sent by the target device after responding to the identifying operation for the identifiable identifier on the data acquisition device.
For example, the data acquisition device is carried on the subject to be tracked and cannot be removed. The user can identify the identifiable mark on the data acquisition device through the target device (a mobile phone and other terminals) (for example, the two-dimensional code is arranged on the data acquisition device, the target device can execute the identification operation through scanning the two-dimensional code), and after the identification operation, an information tracking request for the object to be tracked is sent to the Internet of things, the information tracking request can comprise the identification information of the data acquisition device, the identification information can be obtained through identifying the identifiable mark, and therefore the authenticity and the effectiveness of the data can be further guaranteed.
The object to be tracked is a pheasant, the legs of the pheasant can carry data acquisition equipment, two-dimensional code information is arranged on the data acquisition equipment, a user can scan the two-dimensional code information by using a terminal, so that the terminal can send an information tracking request to an internet of things platform, and the information tracking request can comprise identification information of the data acquisition equipment.
FIG. 3 illustrates a flow chart of a blockchain-based information tracking method in accordance with an embodiment of the present application.
In a possible implementation manner, referring to fig. 3, the generating, according to the first motion information and the second motion information, a tracking result in step 103 may include:
For example, after the data acquisition device acquires the motion information of the object to be tracked, the motion information may be stored in the local and blockchain of the internet of things device. After the internet of things platform receives the information tracking request, the first motion information of the stored object to be tracked can be obtained from the blockchain according to the identification information of the data acquisition device carried in the information tracking request, and the second motion information of the stored object to be tracked can be obtained from the internet of things platform according to the identification information of the data acquisition device carried in the information tracking request, and the internet of things platform can generate a tracking result according to the first motion information and the second motion information.
The tracking result is generated according to the first motion information and the second motion information, so that the possibility of information falsification can be further reduced.
In one possible implementation manner, the generating the tracking result according to the first motion information and the second motion information may include the following steps:

and generating a tracking result according to the second motion information and the comparison result.
The internet of things platform can compare the first motion information of the object to be tracked stored in the blockchain with the second motion information of the object to be tracked stored locally in the internet of things to generate a comparison result. For example: when the first motion information is consistent with the second motion information, a first result may be generated; when the first motion information is inconsistent with the second motion information, a second result may be generated.
The internet of things platform can take the second motion information and the comparison result as tracking results. For example, when the tracking result includes the second motion information and the first result, the second motion information may be indicated as valid and reliable information; when the second motion information and the second result are included in the tracking result, the second motion information may be represented as unreliable information.
In this way, the internet of things platform can verify the validity of the second motion information of the locally stored object to be tracked through the first motion information of the object to be tracked stored in the blockchain, and the reliability and the authority of the tracking result can be further improved.

the first motion information is stored into a local and blockchain.
The preset number may be a preset number in units of number, for example: 2, 3, 4, etc. For example, the data acquisition device may acquire the motion information of the object to be tracked in real time, and report the motion information of the object to be tracked to the internet of things platform in a random time interval or a preset time interval, for example: reporting every 2 hours.
After receiving the preset number of data information sent by the same data acquisition device, the internet of things platform can integrate the motion information in the preset number of data information into first motion information, and can store the first motion information (or a hash value corresponding to the first motion information) into a local and blockchain. For example: the preset number is set to be 6, the data acquisition device reports the motion information of the object to be tracked to the internet of things platform once every 2 hours, and when the internet of things platform receives the 6 th data information sent by the data acquisition device, the internet of things platform can integrate the motion information carried in the 6 th data information and the 5 previous data information (1 st data information-6 th data information) into first motion information, and then store the first motion information in the local and block chains. And when 6 data information (7 th data information-12 th data information) is received again, the motion information carried in the 6 data information is integrated and then stored in the local and blockchain.

The above specified time interval may be a preset value in units of time, for example: 6 hours, 8 hours, 10 hours, etc.
For example, the data acquisition device may acquire the motion information of the object to be tracked in real time, and report the motion information of the object to be tracked to the internet of things platform in a random time interval or a preset time interval.
After receiving the data information sent by the same data acquisition device, the internet of things platform can integrate the motion information carried by the data information in the appointed time interval into second motion information, and can store the second motion information (or a hash value corresponding to the second motion information) into a local and block chain. For example: the preset time interval is 6 hours, and the platform of the internet of things can integrate the motion information carried in the data information sent by all the data acquisition devices received in 6 hours (00:00-6:00) into second motion information, and then store the second motion information in the local and block chains.

The integration as referred to herein includes combining a plurality of pieces of motion information into one set of motion information as either the first motion information or the second motion information.

In the example, the chicken body carries a data acquisition device which is disassembled and destroyed immediately, and the data acquisition device can acquire the motion information such as the step number information, the position information and the like of the chicken motion. After the data acquisition equipment acquires the motion information of the chicken, the motion information of the chicken can be sent to the Internet of things platform, and the Internet of things platform can further store the motion information of the chicken in the blockchain and can obtain the corresponding block identification token.
After purchasing the chicken from the supply platform, the user can inquire the motion information of the chicken through the ID of the data acquisition equipment on the chicken body. For example: the user scans the data acquisition equipment on the chicken body (or directly inputs the ID of the data acquisition equipment on the terminal), and triggers the terminal to send an information tracking request to the Internet of things platform, wherein the information tracking request comprises the ID information of the data acquisition equipment. After receiving the information tracking request, the internet of things platform can acquire a block identification token corresponding to the data acquisition equipment, and acquire first motion information of the chicken from a block chain according to the block identification token.
The Internet of things platform locally stores second motion information of the chicken, after the first motion information of the chicken is obtained from the blockchain, the Internet of things platform can compare the first motion information with the second motion information, generate a tracking result according to the comparison result, and send the tracking result to a terminal of a user.
The terminal may display the tracking result after receiving the tracking result. The user can know the growth cycle information of the chickens according to the tracking result. For example: when the first motion information is consistent with the second motion information, the comparison result is a first result, and the tracking result comprises the second motion information and the first result.
