Detailed Description
The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.
Before describing the method for acquiring the terminal location information, the terminal, the location acquisition terminal and the storage medium provided by the present disclosure, an application scenario and related terms of embodiments of the present disclosure are first described. The technical solutions provided by the following embodiments of the present disclosure may be applied to a wireless communication network, for example: long Term Evolution (LTE) systems, long term evolution advanced (LTE-a) systems, and further evolution networks thereof.
A Base Station (BS) and a User Equipment (UE) may be included in a wireless communication network. The base station may be a device that communicates with a user equipment or other communication station, such as a relay station. A base station may provide communication coverage for a particular physical area. For example, the base station may specifically be an evolved node B (ENB or eNodeB) in LTE; or may be other access network devices providing access services in a wireless communication network.
In the embodiments of the present invention, the UEs may be distributed throughout the wireless network, and each UE may be static or mobile. A UE may be referred to as a terminal (terminal), a mobile station (mobile station), a subscriber unit (subscriber unit), a station (station), etc. The UE may specifically be a cellular phone (cellular phone), a Personal Digital Assistant (PDA), a handheld device (hand-held device), a laptop computer (laptop computer), and other wireless communication devices. When the UE is applied to Machine-to-Machine (M2M) communication, the UE may be referred to as an M2M terminal, and specifically may be a smart meter, a smart appliance, or other devices supporting M2M communication.
Aiming at a block chain, the block chain is a decentralized distributed database system which is maintained by all nodes in a block chain network together, and consists of a series of data blocks generated based on a cryptography method, wherein each data block is a block in the block chain. The blocks are linked together in order according to the chronological order of the generation times, forming a chain of data, which is referred to visually as a chain of blocks.
Description of related concepts involved in blockchain technology:
the user identity: the user identity in the block chain is represented by a public key, the private key corresponding to the public key is mastered by the user and is not issued to the network, the public key becomes an address after specific hash and encoding, and the address represents the user and can be issued at will.
Block chain data writing: blockchain nodes implement writing data to blockchains by issuing "transactions" to the blockchain network. The transaction comprises the signature of the user on the transaction by using the private key of the user so as to prove the identity of the user. Transactions are recorded into the generated new blockchain by miners (blockchain nodes performing blockchain consensus competition mechanisms), then are issued to the blockchain network, and are verified by other blockchain nodes and accepted, and then transaction data are written into the blockchain.
At present, with frequent exposure of illegal monitoring events, users pay more attention to the safety of their own location information, and the operating system of the terminal is also continuously strengthening the management of the device location information. However, for some location information requests, the ue still cannot determine the true source of the location information request. And after the user side responds to the position information request, the sent position information cannot ensure the safety.
In this way, the present application provides a method for acquiring terminal location information based on a blockchain technology, and with reference to a flowchart of the method for acquiring terminal location information shown in fig. 1, the method is applied to a terminal, the terminal is a node of a blockchain network and stores all or part of blocks in the blockchain, and the method includes:
s11, in response to receiving a position information acquisition request sent by a position acquisition end, verifying an acquisition end identity in the position information acquisition request according to a target public key;
s12, if the verification of the position acquisition end identity identification is successful, writing the position information of the terminal into a block of a block chain according to the position information acquisition request;
and S13, sending the block address of the block to the position acquisition end.
In particular, the terminal may be a mobile phone, a tablet computer, or the like. In step S11, the acquiring end identity identifier is generated according to the private key of the location acquiring end. For example, the identity of the collection terminal may be a digital signature of the location collection terminal, and when the location collection terminal sends the location information collection request, the location collection terminal packages a hash value obtained by performing hash operation on its own private key into the location information collection request. After receiving the position information acquisition request, the terminal can verify the digital signature through a target public key to determine whether to respond to the request.
The target public key is a public key of an acquisition end which is authorized or needs to be supported by default and can acquire the position information of the terminal, and the target public key can be stored in the terminal, and the number of the target public keys can be one or more. In an embodiment, the location acquisition end does not obtain the authorization of the terminal before sending the location information acquisition request, and the location acquisition end may send the location information acquisition request and its own public key to the terminal together, so that a user of the terminal determines whether to authorize the location acquisition end. If the terminal authorizes the position acquisition end, the public key of the position acquisition end can be used as the target public key to verify the position information acquisition request. In addition, the terminal can also store the public key to the local so as to verify the subsequent position information acquisition request of the position acquisition terminal.
The position information acquisition request can also comprise a user identifier, and the terminal can also verify the user identifier before verifying the acquisition end identity identifier in the position information acquisition request. For example, the terminal may be a smart phone, and the subscriber Identity may be an IMSI (International Mobile subscriber Identity), an IMEI (International Mobile Equipment Identity), and the like. When receiving the location information acquisition request, the terminal may verify the IMSI and IMEI in the location information acquisition request. And if the verification of the IMSI or the IMEI is failed, not responding to the position information acquisition request.
The location information acquisition request may further include configuration information, and the configuration information may include, for example, a location information sending condition of the terminal. For example, the location information sending condition may include various events that trigger the terminal to send location information, such as a change in a residence area of the terminal, a change in a paging area, a location change exceeding a threshold range, and the like.
In this way, the step S12 is that when the terminal successfully verifies the identity identifier of the location acquisition end and meets the corresponding location information sending condition, the terminal triggers a location information sending event, and writes the location information of the terminal into the block of the block chain.
Further, in step S13, the tile address of the tile may be sent to the location collecting end.
For example, the position collection terminal may be a server providing a motion path monitoring service (e.g., performing summary analysis on the motion path of the user), and the terminal may be a smartphone of the user. After receiving the position information acquisition request of the server, the smart phone can analyze the position information acquisition request. And verifying the digital signature of the server in the position information acquisition request according to a public key in a locally cached public key list, and writing the position information of the smart phone into a block chain according to the configuration information in the position acquisition request after the verification is successful. After the block is generated, a block address of the block is sent to the server.
That is to say, when receiving the location information acquisition request, the smart phone may perform authentication on the sender of the location information acquisition request according to the target public key, and respond to the location information acquisition request with successful authentication, so as to prevent the location information of the terminal from being illegally monitored. In addition, the location information of the smartphone may be stored by writing in a block, and after responding to the location information acquisition request, the location information acquisition request sends a block address of a block in which the location information of the terminal is stored to a server. In this way, the user and the intermediate transmission node cannot tamper with the location information, so that the security and authenticity of the location information of the terminal can be ensured.
It should be noted that in some scenarios requiring continuous acquisition of location information, the configuration information may further include a time period for sending the location information, that is, the terminal needs to send the location information to the location collecting terminal every other time period.
In an embodiment, the configuration information may further include a location information data item requested by the location acquisition end, so as to characterize a type of the data item that needs to be sent by the terminal. The location information data item may include at least one of area identification information, global navigation satellite system GNSS positioning location information, area reference signals, area synchronization signals, area channel state reference signal received power, area downlink reference signal angle of arrival of the terminal. In this way, the terminal can store the data corresponding to each position information data item into a block according to the configuration information, and send the address of the block to a position acquisition end.
In addition, in a possible implementation manner, when the terminal sends the block address of the block to the position acquisition end, the terminal may further encrypt the block address. Thus, the step S13 may include:
and encrypting the block address according to the public key of the position acquisition end, and sending the encrypted block address to the position acquisition end.
It should be understood that, since the private key of the collector is strictly kept secret, the pseudo base station cannot parse the location information even if the pseudo base station receives the location information sent by the user. That is, the protection of the location information transmitted by the user can be achieved by the above method.
In another possible embodiment, the step S12 includes:
and broadcasting the position information of the terminal to the block chain network according to the position information acquisition request.
When any node in the block chain Network generates a block, packing the position information received by the node into the block, and generating a timestamp of the block, where the timestamp includes time information of the position information packed into the block and an SFN (single frequency Network) value of an area to which the terminal belongs at a time corresponding to the time information.
It should be understood that, since the block timestamp carries both the SFN value and the time information of the location information packed into the block, the location collecting end may determine a second time according to the location information (e.g., the camping cell identifier) in the block and the SFN value, and compare the second time with the time information of the location information packed into the block, so as to verify the location information.
Further, the block may further include:
the current block identifier may be, for example, a hash value corresponding to the current block, and is obtained by performing a hash operation on the content included in the current block.
The previous block id may be, for example, a hash value corresponding to the previous block, and is obtained by performing a hash operation on the content included in the previous block.
The currently camped cell identifier may be, for example, a cell ID of the currently camped cell.
In an embodiment, the block may further include an identifier of a previously camped cell, for example, a cell ID of the previously camped cell.
By adopting the storage mode, the difficulty of tampering the position information is increased, so that the authenticity of the position information can be ensured.
It should be noted that, for some scenes with high real-time requirement of location information, before sending the block address of the block to the location acquisition end, the location information of the terminal may also be sent to the location acquisition end.
Thus, referring to the flowchart of a method for collecting terminal location information shown in fig. 2, the method includes:
s21, in response to receiving a position information acquisition request sent by a position acquisition end, verifying an acquisition end identity in the position information acquisition request according to a target public key;
the identity of the acquisition end is generated according to a private key of the position acquisition end, and the target public key is a public key of the acquisition end which is authorized by the terminal and can acquire the position information of the terminal;
s22, if the verification of the position acquisition end identity identification is successful, the position information of the terminal is sent to the position acquisition end according to the position information acquisition request, and the position information of the terminal and the hash value of the position information are written into a block of a block chain;
and S23, sending the block address of the block to the position acquisition end.
It should be noted that, for the location information, the terminal may also perform encryption by using the above-mentioned encryption method for the block address. Namely, the position information is encrypted according to the public key of the position acquisition end, and the encrypted position information is sent to the position acquisition end.
In this way, the location collecting end can compare the received location information with the location information obtained by the received block address to confirm the authenticity of the location information. Meanwhile, the method also meets the requirement of real-time performance.
In an embodiment, the hash value of the location information may also be stored in the block. Therefore, the position acquisition end can perform hash operation on the received position information, and compares the obtained hash value with the hash value in the block to determine the authenticity of the position information. In this way, the location information of the terminal does not need to be stored in the block, and therefore the space of the block can be saved.
The present disclosure also provides another method for acquiring terminal location information, where the method is applied to a location acquisition end in the above embodiments, where the location acquisition end is a node of a block chain network and stores all or part of blocks in a block chain. Referring to fig. 3, a flowchart of a method for collecting terminal location information is shown, the method including:
s31, sending a position information acquisition request to a terminal, wherein the position information acquisition request comprises a position acquisition end identity identifier, and the position acquisition end identity identifier is generated according to a private key of the position acquisition end;
and S32, receiving the block address sent by the terminal.
S33, searching the corresponding block in the block chain according to the block address, and obtaining the position information of the terminal from the block.
Specifically, the position acquisition end may be a server, a base station, or the like. In step S31, the identity identifier of the collection end may be, for example, a digital signature of the location collection end, and when the location collection end sends the location information collection request, the location collection end packages a hash value obtained by performing a hash operation on its own private key into the location information collection request.
In an embodiment, the location acquisition end does not obtain the authorization of the terminal before sending the location information acquisition request, and the location acquisition end may send the location information acquisition request and its own public key to the terminal together, so that a user of the terminal determines whether to authorize the location acquisition end.
The location information acquisition request may further include a user identifier for distinguishing different terminals. For example, the terminal may be a smart phone, and the subscriber Identity may be an IMSI (International Mobile subscriber Identity), an IMEI (International Mobile equipment Identity), and the like. And the position acquisition end realizes the acquisition of the position information of the appointed terminal by setting the user identification in the position information acquisition request.
In step S32, the location collection end may receive the block address sent by the terminal, and analyze the block address.
In step S33, the location collecting end may search a corresponding block in a block chain according to the block address, and further obtain location information of the terminal from the block.

In addition, the authenticity of the position information is also ensured by a mode of acquiring the position information through the block address.
In one possible implementation, the step S32 includes:
and analyzing the block address according to the private key of the position acquisition end.

By adopting the mode, the authenticity of the position information acquired by the position acquisition end can be further ensured.
In another possible embodiment, the method comprises:
receiving the position information sent by the terminal;
and comparing the position information with the position information of the terminal obtained from the block to verify the position information of the terminal.
Similarly, the location information is encrypted according to the public key of the location acquisition end, and the terminal responds to the location information acquisition request of the location acquisition end and sends the location information to the location acquisition end before sending the block address to the location acquisition end. Therefore, by receiving the position information sent by the terminal, the position acquisition terminal can provide a service based on the position information for the terminal user according to the position information, and the corresponding real-time requirement is met. Further, after receiving the block address, the location acquisition end may compare the location information with location information of the terminal obtained from a block corresponding to the block address, so as to verify the location information of the terminal, thereby ensuring authenticity of terminal information.

In some scenarios where location information needs to be continuously acquired, the configuration information may further include a time period for sending the location information, that is, the terminal needs to send the location information to the location acquisition end every other time period. The time period may be in minutes, seconds, time granularity, such as 1 minute, 10 seconds, 30 seconds, and so forth.
In an embodiment, the configuration information may further include a location information data item requested by the location acquisition end. The location information data item may include at least one of area identification information, global navigation satellite system GNSS positioning location information, area reference signals, area synchronization signals, area channel state reference signal received power, area downlink reference signal angle of arrival of the terminal.
Thus, in a possible embodiment, the method further comprises verifying the location information of the terminal by at least one of:
if the area identification information in the position information of the terminal is the same as the geographical position represented by the GNSS positioning position information, determining that the position information of the terminal is valid;
if the geographic position represented by the area reference signal in the position information of the terminal is the same as the geographic position represented by the GNSS positioning position information, determining that the position information of the terminal is valid;

and if the geographic position represented by the area downlink reference signal arrival angle in the position information of the terminal is the same as the geographic position represented by the GNSS positioning position information, determining that the position information of the terminal is valid.
The area identification information may be, for example, a cell identification. In specific implementation, the position acquisition end may determine the geographical position boundary of the cell coverage area according to the cell identifier, and then perform determination according to the GNSS position information. And if the geographic position represented by the GNSS position information is within the geographic coverage boundary range of the cell represented by the cell identifier, determining that the position information is valid.
Similarly, the position acquisition end may perform multi-point positioning calculation according to the reference signal/synchronization signal/channel state reference signal received power of the plurality of cells, so as to obtain the position of the terminal. And if the deviation between the calculated position of the terminal and the geographical position represented by the GNSS position information in the position information sent by the terminal is less than a preset threshold value, determining that the position information is valid.
