Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention.

People usually share information through social software, such as WeChat, QQ, Facebook, microblog and the like, and can share the current address (address is also called geographical position and position) while sharing the information. Taking the example of publishing the dynamics of the friend circle by 'WeChat', the terminal of the user can receive 'shared content' input by the user, select a visible friend circle and select the 'location', and when the terminal receives an input request for acquiring the 'location', the terminal of the user can acquire the current location of the user by a positioning module, including GPS positioning, WIFI positioning and the like. After the user clicks the 'release', a sharing request is generated according to 'sharing content' input by the user and the selected 'location', the sharing request is further sent to the server, and the server sends the sharing content and the sharing address to each friend in the visible circle of friends after receiving the sharing request.

However, the above-mentioned method for determining the current geographic location has the following problems that ① is easy to directly tamper with the actual location of the user through software (e.g., modified location software simulate 4.0.2, XCode development tool) or a program, for example, the user can change the currently acquired geographic location by modifying longitude and latitude and address name, so as to acquire false location information, so that a minder can take advantage of the machine to perform cheating action by using a false address, ② a third party service platform manages the acquired address data, belongs to a centralized architecture, has absolute processing rights to the data, and the trust of the third party service platform cannot be guaranteed, which may result in the damage to the benefits of the user, for example, the historical address of the user is tampered, or the historical address of the user information is lost.

In order to solve the above problem, an embodiment of the present invention provides an information sharing scheme based on a block chain. The block chain is a novel application mode of computer technologies such as distributed data storage, point-to-point transmission, a consensus mechanism, an encryption algorithm and the like, and is essentially a decentralized database. In the scheme, the terminal uploads the current address of the terminal to the block chain network at regular time, and then the block chain network stores the uploaded address. When a user uses a location-dependent sharing function, such as sharing a current location during chatting, sharing a current location during publication dynamically, and so on. The terminal acquires the historical uploading position of the user from the blockchain network, namely the historical position, and judges whether the current position of the user is credible according to the acquired historical position of the user. Based on the above scheme, an embodiment of the present invention provides an information sharing system, such as the information sharing system shown in fig. 1, where the information sharing system may include a terminal 101, a block chain network 102, and a server 103. Wherein:

the terminal 101 can perform information interaction with the server 103 based on the client. For example, the terminal 101 interacts with the server 101 (in this case, a server for wechat) based on the application program "wechat" to realize various functions in "wechat", such as chatting, sending a circle of friends, and the like. For another example, the terminal 101 interacts with the server 101 (the server of the new wave microblog in this case) based on the application program "new wave microblog" to realize various functions in "new wave microblog", such as dynamic release, news browsing, and the like. When the user shares information through the terminal 101, for example, a friend group is released or a dynamic state is released, the current address can be acquired, and then the current address is shared, so that friends, netizens or other people can know the address of the friend, and the user experience is improved. The terminal 101 may be a plurality of types of devices, such as a mobile phone, a computer, a smart watch, an unmanned aerial vehicle, and the like.

To improve the reliability of the current address issued by the terminal 101, the terminal 101 may join the blockchain network 102 to become a node in the blockchain network 102. The terminal 101 may obtain the current location at regular time and upload the current location to the blockchain network 102, and all nodes in the blockchain network 102 store the current location through consensus computation.

Each node in the blockchain network 102 may receive the current address uploaded by each terminal 101 at regular time, and store the address uploaded by each terminal 101 through a consensus mechanism, P2P transmission, and the like. In the embodiment of the present application, the address stored by the blockchain network 102 is also referred to as a history address.

When the terminal 101 shares information, an address uploaded by the terminal 101, such as an address (i.e., a target history address) uploaded by the terminal 101 last time, may be acquired from the block chain network 102, and then a sharing request carrying the last uploaded address, the shared content, and the current address is sent to the server 103, and after receiving the sharing request, the server 103 may verify whether the current address is trusted based on the last uploaded address and the current address, for example, when the last uploaded address is "shengxian" uploaded when the last uploaded address is 10 month 1 day 8, the current address at current time 10 month 1 day 9 is "beijing train station", and since the current transportation cannot reach the beijing train station from the shengxian building of shengxian in one hour, the current address "beijing train station" is considered to be untrusted. At this time, the server 103 may not respond to the sharing request, or may send information for prompting that the current address is wrong to the terminal 101; otherwise, when the current address is trusted, the server 103 may send the shared content and the current address to the circle of friends of the user corresponding to the sharing request.

In one implementation, the server 103 may also be a node in the blockchain network 102. At this time, the sharing request sent by the user's terminal 101 may not carry the last address uploaded by the terminal 101 from the blockchain network 102, but the server 103 obtains the last address uploaded by the terminal 101 from the blockchain network 102, so as to verify the credibility of the current address.

Therefore, the information sharing scheme provided by the embodiment of the invention has the advantages that ① is added with a verification link for a traditional acquisition positioning mode to check the authenticity of positioning acquired by a user and reduce the possibility of potential deceptive action, ② utilizes the decentralized characteristic and the open transparency of a block chain to ensure that uploaded data is independent of a third-party management platform, so that the safety and reliability of the data are guaranteed, the data are not easy to lose, the manipulation right of the third-party management platform on the data is limited, and the data cannot be modified randomly.

Based on the above description, an embodiment of the present invention provides an information sharing method, which can be executed by the above-mentioned information sharing system. Wherein the terminal of the first user may be terminal 101, the blockchain network may be blockchain network 102, and the server may be server 103. The information sharing method can comprise the following partial or all steps: referring to fig. 2, fig. 2 is a flowchart illustrating a method for storing an address of a user through a blockchain network according to an embodiment of the present disclosure.

S202, the terminal of the first user joins the block chain network.

First, a terminal of a first user creates a first key pair using an asymmetric encryption algorithm. Wherein the first key pair comprises a first public key and a first private key. In the embodiment of the application, a first private key is used for signing a current address when a terminal of a first user uploads the current address to a block chain network at regular time so as to indicate that the current address belongs to the first user; the first public key is used to verify addresses signed by the first private key and uploaded into the blockchain network. After the first secret key pair is created, the terminal of the first user can upload the first public key in the first secret key pair to the block chain network, so that other nodes in the block chain network can receive the public key of the first user, and an address uploaded by the terminal of the first user can be screened out from historical addresses stored in the block chain network according to the public key of the first user; the terminal of the first user also sends the first public key to the server to cause the server to establish an association of the first public key with the account of the first user. And the first private key is kept by the terminal of the first user.

After the terminal of the first user creates the first secret key pair and uploads the first public key to the blockchain network, it indicates that the terminal of the first user has joined the blockchain network and has completed identity registration in the blockchain network, and becomes a node in the blockchain network.

And S204, the terminal of the first user acquires the current address of the first user at regular time.

The terminal of the first user signs an intelligent contract using the position information, and the intelligent contract comprises that the terminal of the first user uploads the current address of the first user to the block chain network at regular time so that the block chain network stores the current address. When the first user completes the signing of the intelligent contract, the terminal of the first user is qualified to upload the address and view the historical address in the blockchain network.

First, the terminal of the first user may periodically obtain the current address of the first user through a positioning module, such as a GPS module, a WiFi positioning module, and the like. The timing may be a frequency preset in the smart contract, and for example, the address of the user may be acquired every 30 minutes, or the address of the user may be acquired at the same time every day. The current address can be in the form of latitude and longitude coordinates, can also be in the form of a specific location name, and can also be in other forms capable of representing the location. For example, the terminal of the first user acquires the current address of the first user through the GPS positioning module at frequency a.

S206, the terminal of the first user uploads the current address acquired at fixed time to the block chain network.

The terminal of the first user regularly uses the private key of the first user to sign the current address of the first user to generate first data, and the first data is uploaded to the block chain network, so that the current address of the first user is stored in the block chain network.

After the terminal of the first user acquires the current address, the terminal of the first user signs the current address by using the first private key to generate first data. The terminal of the first user then broadcasts the first data to other nodes in the blockchain network so that the blockchain network stores the first data via P2P communication, consensus algorithm. In one implementation, other nodes in the blockchain network receive the first data, wherein the node with the highest computation speed preferentially packs the first data into the latest block, and then broadcasts the latest block, so that other nodes in the blockchain network synchronize the block into the blockchain stored by the node after receiving the latest block.

When the user uses the function related to the position sharing in the information sharing process, the terminal of the user can acquire the historical uploading position of the user from the blockchain network, and therefore whether the sharing position of the user is credible or not is verified according to the historical uploading position of the user.

Referring to fig. 3, fig. 3 is a flowchart illustrating information sharing according to an embodiment of the present disclosure. At this time, the terminal of the first user is a node in the blockchain network, and the server may be a node in the blockchain network, and the method may include the following steps:

s302, a terminal of a first user receives a sharing instruction for information to be shared, wherein the sharing instruction is used for indicating that the information to be analyzed is sent to each contact in a contact set, and the information to be shared comprises shared content and a shared address.

Referring to fig. 4, fig. 4 is a schematic view of a user interface for sharing information according to an embodiment of the present disclosure. The information sharing user interface includes: publishing control 401, content input control 402, address selection control 403, prompt contact selection control 404, and sharing scope selection control 405. After detecting the shared content input for the content input control 402, the terminal displays the shared content, where the shared content may include characters, pictures, short videos, and the like; after detecting user operation for the address selection control 403, the terminal acquires a current address through the positioning module, recommends a plurality of candidate addresses under the current address to a user based on the current address, and after receiving selection operation for one address in the candidate addresses, takes the selected address as a sharing address and displays the sharing address; after detecting user operation input by the prompt contact selection control 404, the terminal selects a contact needing to be reminded from a contact set (such as a contact list) of the user; after detecting the user operation input by the sharing range selection control 405, the terminal may select a contact, which may view information to be shared, from the contact set of the user. Wherein the contact set or list is a contact of the first user, such as a friend in the "WeChat" of the first user. The terminal triggers the terminal to execute S304 and S306 when detecting the user operation input for the publication control 401.

S304, the terminal of the first user obtains the target historical address of the first user from the block chain network. And the target historical address of the first user is uploaded by the terminal of the first user and is stored in the block chain network.

In a first implementation of S304, the target historical address may be the last address uploaded by the terminal of the first user. At this time, the acquiring, by the terminal of the first user, the target history address may include steps S3041 to S3042:

s3041, the terminal of the first user obtains the historical address of the first user from the blockchain network according to the public key of the first user.

Because the historical address in the block chain network is uploaded by the terminal of the user through the private key signature, the public key corresponds to the private key one by one, and only the public key corresponding to the private key can be verified through the address uploaded through the private key signature. Therefore, the historical address uploaded by the private key signature of the first user can be acquired in the blockchain network through the public key of the first user.

S3042, the terminal of the first user determines that the target historical address is a historical address closest to the current time in the historical addresses of the first user, where each historical address in the historical addresses of the first user corresponds to a time.

The blockchain network may record the time of receiving the address, also referred to as a timestamp, while storing the address of each first user. At this time, the terminal of the first user may acquire the last recorded history address from the blockchain network and use it as the target history address.

In a second implementation of S304, the target historical address may include a plurality of addresses from the historical addresses of the first user. At this time, the acquiring of the target history address by the terminal of the first user may include the steps of:

s3043, the terminal of the first user obtains the historical address of the first user from the blockchain network.

For specific implementation of step S3043, reference may be made to the related description in step S3041, which is not described herein again.

S3044 the terminal of the first user determines a history address with a frequency greater than a first threshold in the history addresses of the first user as a target history address.

And the terminal of the first user counts the occurrence frequency of each historical address in all the historical addresses of the first user, and takes the historical address with the occurrence frequency greater than a first threshold value as a target historical address. Generally, addresses that are frequently present by the first user may be considered authentic addresses, e.g., the first user's home address, corporate address, school address, etc., may be addresses that are frequently present by the first user, and therefore appear more frequently in the blockchain network than other addresses. At this time, the target history address may include a plurality of addresses. The first threshold value may be set differently according to different requirements in practical applications. For example, the first threshold value is set to 1 time. The terminal of the first user counts the frequency of each historical address in all the historical addresses of the first user: the address a is 3 times; address b: 1 time; address c: 6 times. At this time, the target history address may include address a, address b, and address c. It should be understood that when the server determines whether the shared address is trusted, when the shared address of the first user is the address c, the address c may be considered trusted; when the sharing address of the first user is the address b, the address b can be considered as credible; when the shared address of the first user is the address d, the address d does not appear in the historical address, and the address d can be considered to be not trusted.

In the third implementation of S304, the target historical address may include a plurality of addresses corresponding to respective times, where each address corresponding to a time may be an address with the highest frequency in the historical addresses uploaded by the terminal of the first user at the time. Therefore, the method counts the life rules of the user and can know the places where the user is most likely to be at the time.

It should be noted that, the implementation is not limited to the two implementations, and step S304 may also include other implementations, which are not described herein again.

S306, the terminal of the first user generates a sharing request according to the sharing instruction and the target historical address, and sends the sharing request to the server.

The sharing request carries a target historical address, sharing content, a sharing address and a contact set, and is used for requesting the server to send the sharing content and the sharing address to each contact in the contact set.

S308, the server receives the sharing request.

Specifically, the server may parse the target history address, the shared content, the shared address, and the like from the sharing request.

S310, the server identifies whether the sharing address is credible according to the sharing address and the target historical address.

Before responding to the sharing request, the server first determines whether the sharing address is trusted. Since the sharing request carries the target history address carried by the tag from the blockchain network, the server can identify whether the sharing address is trusted based on the relationship between the target history address and the sharing address.

For example, for the first implementation of S302, the target historical address is an address uploaded last time from among historical addresses uploaded by a terminal of a first user in the blockchain network. At this time, the server may identify a distance between the target history address and the shared address, a time difference between times corresponding to the target history address and the shared address, and the like, and when the time difference is smaller than a time threshold, for example, 5min, 10min, 30min, or other time lengths, if the distance is greater than a distance threshold, for example, 10km, 20km, 50km, and the like, the shared address is considered to be not trusted, and otherwise, the shared address is considered to be within a reasonable range and is considered to be trusted. In another implementation, if the frequency of uploading the current address to the block chain network by the terminal of the user may be once every 10 or 20 minutes, the server may also determine whether the shared address is trusted only by the distance, and if the distance is greater than a distance threshold, such as 10km, 20km, 50km, and the like, the shared address is considered to be not trusted, otherwise, the shared address is considered to be within a reasonable range and is considered to be trusted.

In another implementation, the server identifies whether the shared address is trusted based on the distance and the time difference, and the specific implementation may include the following steps:

s3101, the server may determine the speed of reaching the shared address from the target historical address according to the target historical address, the shared address, the timestamp of the target historical address, and the current time.

Firstly, the server calculates the distance between a target address and a shared address according to the target historical address and the geographic position of the shared address; further, calculating the time difference between the time stamp of the target historical address and the current time according to the time stamp of the target historical address and the current time; then, an average speed between the arrival at the shared address from the target history address is calculated based on the distance and the time difference.

S3102, when the speed of the target historical address reaching the sharing address is not greater than the speed threshold value, the server determines that the sharing address is credible. If the shared address is trusted, S312 is executed, otherwise S314 is executed.

In one embodiment, the speed threshold used to identify whether the shared address is authentic may be a fixed value.

In one embodiment, the speed threshold for identifying whether the shared address is trusted may be a variable value, the server may store a correspondence between the speed threshold and the address type, the server may determine the address type of the target historical address before performing S3102, determine the speed threshold corresponding to the address type of the target historical address according to the correspondence between the address type and the speed threshold, and further determine that the shared address is trusted when the speed at which the target historical address reaches the shared address is not greater than the speed threshold corresponding to the address type of the target historical address. The address types may include, among others, airports, train stations, subway stations, bus stations, and the like. The speed threshold corresponding to an address type represents the maximum speed that can be achieved by a vehicle moving at that address type. For example, the speed threshold value for an airport may be determined based on the maximum speed at which the aircraft is flying, and 1000km/h may be taken as the maximum speed at which the aircraft is flying, and then the corresponding speed threshold value for the airport is 1000 km/h. And finally, comparing the average speed between the target historical address and the current address with the speed threshold corresponding to the target historical address, if the average speed is not greater than the speed threshold, the shared address is credible, and if the average speed is greater than the speed threshold, the shared address is not credible. For example, the target history address is "Shenzhen Jeans airport", the sharing address is "Chongqing", the time difference is "30 minutes", the average speed can be calculated to be greater than the speed threshold value 1000km/h, and the sharing address "Chongqing" can be judged to be untrustworthy.

For another example, for the second implementation of S302, the target historical address may include a plurality of addresses. At this time, the server may determine whether the shared address is an address among the plurality of addresses included in the target historical address, and if so, the shared address is considered to be trusted, otherwise, the shared address is considered to be untrusted. In another implementation, each of the target historical addresses may include one or more times, respectively, to indicate that each address is often uploaded to the blockchain network at those times.

For another example, for the third implementation of S302, the target historical address may include a plurality of addresses corresponding to respective times, where the address corresponding to each time may be the next highest address in the historical addresses uploaded by the terminal of the first user at the time. The server can determine an address corresponding to the current time from the target historical address, and further determine whether the shared address is the address corresponding to the current time, or determine whether the shared address is in an address range determined by the address corresponding to the current time, if so, the shared address is considered to be trusted, otherwise, the shared address is considered to be not trusted.

S312, the server sends the sharing information to each contact in the contact set.

And when the server judges that the sharing address of the first user is credible, the sharing information is sent to each contact in the contact set. Referring to fig. 5, fig. 5 is a schematic view of a user interface for displaying sharing information according to an embodiment of the present disclosure. After a first contact in the contact set receives the sharing information of the first user, the sharing information of the first user can be displayed at a terminal of the first contact. As shown in fig. 5, the user interface diagram may show: the username and avatar of the first contact, at least one dynamic display area 501. The dynamic display area 501 may display: the system comprises a head portrait of a first user, a user name of the first user, shared content shared by the first user, a shared address of the first user, a block chain verification mark and the like. The block chain verification mark is used for identifying that the address shared by the first user is verified according to the historical address of the first user in the block chain, and the shared address is indicated to be credible; when the block chain verification is not passed, the block chain verification flag will not be displayed here, or an identifier that the block chain authentication is not passed will be displayed.

It should be noted that, the user interface diagrams shown in fig. 4 and fig. 5 are not limited, and other user interfaces may be designed according to the functional requirements, the user experience, and the like.

And S314, the server sends prompt information for indicating the current address error to the terminal.

And when the server judges that the sharing address is not credible, generating prompt information, wherein the prompt information is used for prompting that the sharing address of the first user is wrong or not credible, and sending the prompt information to the terminal of the first user.

When the server determines that the sharing address of the first user is not trusted, the server may also perform other operations, for example, the server may also perform S602, and send the to-be-analyzed information to the terminal of each contact in the contact set, and at the same time, send the indication information indicating that the sharing address is not trusted, so that the terminal of each contact in the contact set may display that the sharing address is not trusted after receiving the indication information. As shown in fig. 5, in the user interface, which is a display interface that a terminal of a contact in a contact set outputs after receiving shared information and indication information, the display interface may display the received shared information of the contact (including a first user), at this time, the display area 5015 displays the received shared information from the first user, and it is untrusted that a shared address of the first user does not pass authentication of a blockchain network by an identifier.

In another embodiment of the present application, the server may join the blockchain network, and the step S304 described above, that is, the target history address of the first user is obtained from the blockchain network, may also be executed by the server, where the analysis request may not carry the target history address, and the server obtains the target history address from the blockchain network. For a specific implementation that the server can join the blockchain network, reference may be made to the specific implementation that the terminal of the first user joins the blockchain network, which is not described herein again. As shown in fig. 6, which is a flowchart of information sharing provided in the embodiment of the present application, the method may include the following steps:

s602, a terminal of a first user receives a sharing instruction for information to be shared, wherein the sharing instruction is used for indicating that the information to be analyzed is sent to each contact in a contact set, and the information to be shared comprises shared content and a shared address.

Step S602 and step S302 are synchronized, and specific implementation may refer to relevant description in step S302, which is not described herein again.

And S604, the terminal of the first user generates a sharing request according to the sharing instruction, and sends the sharing request to the server.

Unlike in FIG. 3 described above, the share request does not carry the destination history address. At this time, the sharing request carries the sharing content, the sharing address, the contact set and the like.

S608, the server receives the sharing request.

And the server analyzes the shared content, the shared address, the contact set and the like from the sharing request.

S610, the server acquires the target historical address of the first user from the block chain network.

In this embodiment, the server is a node in the blockchain network, and the server may obtain the historical address of the first user from the blockchain network, where the specific implementation of the server may include steps S6101 and S6102.

S6101, the server determines the public key of the first user according to the corresponding relationship between the user and the public key.

The server may obtain the first public key according to the correspondence between the account of the first user and the first public key.

S6102, the server obtains the history address of the first user from the block chain network according to the public key of the first user.

The target historical address of the first user may be one or more addresses, and specific implementation may refer to relevant descriptions in the three implementation manners of step S304, which are not described herein again.

And S612, the server identifies whether the sharing address is credible according to the sharing address and the target historical address.

The detailed implementation of the step of executing step S310 is not described herein again. And executing S614 when the sharing address is judged to be credible, otherwise, executing S616.

And S614, the server sends the sharing information to each contact in the contact set.

And S616, the server sends prompt information for indicating the current address error to the terminal.

The specific implementation of step S614 and step S312, and step S616 and step S314 may refer to the related description in step S312 and step S314, respectively, which is not described herein again.
