Description

Technical Field

[0001] The present invention relates to the technical field of social network, and in particular to a personal mobile decentralized AI social method based on USB shield and SIMKey. Background Art

[0002] Traditional social media generally stores the social information of space owners and fans on the servers of social media. When individuals do not use the social media, it is difficult to know whether they have really deleted their personal information. Although some platforms have also encrypted personal information, the decryption key is not in the hands of the user. Of course, foreign countries have also made many solutions based on decentralized protocols such as Nostr, ActivityPub, Farcaster, Lens Protocol, etc., but these solutions usually host the keys on third-party servers and lack integration with user hardware authentication devices, and also cannot provide the highest level of data protection.

[0003] In addition, traditional social media requires fans to read one article or one video at a time to understand the message that the space owner wants to convey. This method is too inefficient. With the development of AI technology, the space owner packages all articles and other original knowledge into an AI knowledge base, and delivers information to fans in the form of AI question and answer. It is more efficient and helps protect the copyright of the space owner's original knowledge, which is not easy to be copied by others, and can make the original knowledge available but invisible. Summary of the invention

[0004] The purpose of the present invention is to provide a personal mobile decentralized AI social method based on U shield and SIMKey to overcome the defects of imperfect data protection and low reading efficiency of traditional decentralized protocols in the prior art.

[0005] In order to achieve the above-mentioned object of the invention, the present invention provides the following technical solutions:

[0006] The present invention provides a personal mobile decentralized AI social method based on U shield and SIMKey, including a space host, a SIMKey manufacturer service end or a U shield manufacturer service end and a fan end, including the following steps:

[0007] (1) The user purchases and registers a hardware device, performs initial configuration on the hardware device, and logs in to the hardware device; the hardware device includes a SIMKey terminal or a USB shield terminal, and the user includes a space owner and a fan;

[0008] (2) The space master builds an AI knowledge base based on the SIMkey or U shield and opens it to the outside world. The SIMKey manufacturer server or U shield manufacturer server creates a user space instance for the space master. At the same time, the space master builds a user space instance locally on the SIMkey or U shield.

[0009] (3) The fan accesses the address of the user space instance corresponding to the AI ​​knowledge base of the SIMKey manufacturer server or the U-Shield manufacturer server through the SIMkey terminal or the U-Shield terminal. After paying attention to the cloud user space instance corresponding to the AI ​​knowledge base, the SIMKey manufacturer server or the U-Shield manufacturer server builds a cloud user bridge for the space owner and the fan. After the cloud user bridge is built, the space owner and the fan obtain their respective public and private keys for sending and receiving from the cloud user bridge, and then build their own local user bridges on the SIMkey terminal or the U-Shield terminal. After the local user bridge is built, the public and private keys for sending and receiving are deleted from the cloud user bridge, and a symmetric encryption key is randomly generated. The symmetric encryption key will be saved in the user bridge table of the local SQLite database. The user bridge table is used to encrypt the sending and receiving information of the cloud user bridge and save it to the local user bridge. The query record can be viewed locally later through this symmetric encryption key;

[0010] (4) Fans ask questions through the user bridge. The cloud user bridge of the SIMKey manufacturer server or the U shield manufacturer server forwards the questions to the local user bridge of the space owner. The AI ​​knowledge base of the SIMkey or U shield of the space owner responds to the questions and then forwards the answers to the fans through the cloud user bridge of the SIMKey manufacturer server and the U shield manufacturer server.

[0011] (5) If a fan cancels his / her subscription, the SIMKey manufacturer's server or the USB shield manufacturer's server will destroy the cloud user bridge between the fan and the space owner;

[0012] (6) The space owner cancels the opening of the AI ​​knowledge base to the outside world, and the SIMKey manufacturer's server or the U-Shield manufacturer's server destroys the cloud user space instance.

[0013] Furthermore, the space host and fan end include a SIMKey end, a U shield end and a personal cloud;

[0014] The SIMKey terminal includes a mobile client app, a SQLite database encrypted by SQLCipher, a social space, a SIMKey secure storage area and a knowledge base file;

[0015] The U shield terminal includes PC client software, SQLite database encrypted by SQLCipher, social space, U shield private area, knowledge base file, thinking model and question-answer model;

[0016] The U-Shield private area and SIMKey secure storage area include the key of the SQLite database encrypted by SQLCipher;

[0017] The personal cloud includes personal network disk, git repository, thinking model, question-answer model, SQLite database and data located in the U-shield private area and SIMkey secure storage area;

[0018] The social space is a collection of question-and-answer records between fans and space owners, used to store all encrypted question-and-answer data, and is divided into a cloud social space and a local social space;

[0019] The SIMKey manufacturer server or the U-Shield manufacturer server includes a social space, a relational database, a non-relational database and an application program;

[0020] The social space is subordinate to the user space, the user space is subordinate to the user space instance, and the user space instance is subordinate to the user bridge;

[0021] The relational database includes a user table and a user space table, which are mainly used for user identity authentication and management of user spaces and their instances;

[0022] The non-relational database is used to store user bridge information;

[0023] The application includes authentication services and space management services.

[0024] Furthermore, the SIMKey terminal or USB shield terminal needs to be purchased and activated by real name;

[0025] When the user logs in to the hardware device in step (1), the SIMKey manufacturer server or the U-Shield manufacturer server will perform triple verification of the user's identity through the authentication service of the application: the SMS verification code received by the mobile phone number, the user-defined password of the hardware device, and the unique identifier of the hardware device.

[0026] Furthermore, the AI ​​knowledge base includes a knowledge base file, a thinking model, a question-answering model, and an inquiry template;

[0027] The thinking model is a general large model generated by data and computing power;

[0028] The question-answering model is used to connect the thinking model with the local personal knowledge base file, and provide APIs for knowledge base upload, download and question-answering;

[0029] The inquiry template includes a template name, a corresponding knowledge base file, an address of a thinking model, an address of a question-and-answer model, an inquiry prompt, thinking model parameters and question-and-answer model parameters; fans can use the inquiry template to ask questions they need to ask, and the inquiry template data is saved in the inquiry template table of the local SQLite database of the U-Shield and SIMKey.

[0030] Furthermore, the method for constructing the AI ​​knowledge base includes the following steps:

[0031] The space owner creates a knowledge base file through the U-Shield or SIMKey terminal, then puts the knowledge base file into personal files, and transfers the knowledge base file to the local or cloud question and answer model through the question and answer model's API, and then sets the thinking model and inquiry template for the question and answer model to form an AI knowledge base and provide the ability to answer fans' questions.

[0032] Furthermore, the user bridge includes a cloud user bridge and a local user bridge, and the user bridge is used to connect the AI ​​knowledge base of fans and space owners.

[0033] Furthermore, the access address of the user space instance in step (3) is {social domain name or IP address of the U shield and SIMKey manufacturer} / {user space name} / {user space instance name}; the access address of the cloud user bridge in step (3) is {social domain name or IP address of the U shield and SIMKey manufacturer} / {user space name} / {user space instance name} / {user bridge name};

[0034] The user space name is the user name set by the user of the U shield end and the SIMkey end when opening the social space on the U shield manufacturer server and the SIMKey manufacturer server. It is also the user space folder name. The name can be defined by the user and is stored in the user table of the relational database of the U shield manufacturer server and the SIMKey manufacturer server.

[0035] The user space instance name is the name taken when the user's AI knowledge base is open to the public. It is unique under the same user name and is also the user space instance folder. The name can be defined by the user; the user space instance name is stored in the user space table of the relational database of the U shield manufacturer server and the SIMKey manufacturer server;

[0036] The user bridge name is the user bridge folder name under the user space instance folder, and is unique under the same user space instance folder. Since the folder name is also the key in the non-relational database used to store user bridge information, it is also unique in the entire non-relational database that stores user bridge information. The name is a non-repeating unique value randomly generated by the U-Shield manufacturer server and the SIMKey manufacturer server.

[0037] Furthermore, in step (4), the communication content of the fans asking questions through the user bridge is end-to-end encrypted;

[0038] The end-to-end encryption specifically means that from the time the fan starts asking the question to the time the fan receives the reply from the space owner's AI knowledge base, the message passes through 8 send and receive boxes, namely: the send box and inbox in the local user bridge between the fan and the space owner on the fan side; the fan send box and inbox and the space owner send box and inbox in the cloud user bridge between the fan and the space owner; the send box and inbox in the local user bridge between the fan and the space owner on the space owner side.

[0039] Furthermore, the end-to-end encryption comprises the following steps:

[0040] (a) The fan encrypts the inquiry content with the "symmetric encryption key of the user bridge recorded in the user bridge table of the SQLite database where the outbox is located", and then writes the encrypted inquiry content and inquiry time into a json data array in the json file of the question and answer content in the local outbox folder. The text length of the fan's inquiry content cannot exceed the space limit;

[0041] (b) After the fan-side outbox receives a new record, the question and answer content in the record is decrypted with "the symmetric encryption key of the user bridge recorded in the user bridge table of the SQLite database where the outbox is located", and then encrypted with "the outgoing public key of the user bridge recorded in the user bridge table of the SQLite database where the outbox is located", and then the encrypted inquiry content and inquiry time are combined into a json data and written into the array of the json file of the question and answer content in the fan outbox folder of the cloud user bridge;

[0042] (c) After the fan outbox in the cloud user bridge receives a new record, if the fan's token value is greater than the token value consumed by the space master user for a single fan outbox, the record will be written into the array of the json file of the question and answer content in the space master inbox folder of the cloud user bridge. After writing, the record in the fan outbox in the cloud user bridge will be deleted. At the same time, the fan's token value will be deducted from the token value consumed by the space master user for a single fan outbox. These token values ​​are recorded in the non-relational database used to store user bridge information on the SIMKey manufacturer's server or the U-Shield manufacturer's server;

[0043] (d) When the space master successfully logs in to the SIMKey manufacturer's server or the U-Shield manufacturer's server, the space master takes out the record from the space master's inbox in the cloud user bridge, and decrypts the query content of the record using "the space master's local user bridge corresponding to the cloud user bridge recorded in the user bridge table of the local SQLite database of the user bridge"; if the text length of the query content does not exceed the space master's quota limit, the query content is submitted to the AI ​​knowledge base corresponding to the user space instance of the upper-level user bridge, otherwise the query content is not submitted to the AI ​​knowledge base, and the query answer with the text length exceeding the limit is directly given; at the same time, the query question is encrypted using "the symmetric encryption key of the user bridge recorded in the user bridge table of the SQLite database of the user bridge where the user bridge is located" to form a json data together with the query time and written into the array of the json file of the question and answer content in the inbox folder of the space master's local user bridge. After writing is completed, the record of the space master's inbox in the cloud user bridge is deleted;

[0044] (e) After receiving the inquiry question, the AI ​​knowledge base will give the inquiry answer (if the inquiry answer is complex, the answer will be given in batches and if the token value of the fan is exhausted in the subsequent steps, the answer will be stopped); after receiving the inquiry answer (including the inquiry answer with a text length exceeding the limit given when the text length of the inquiry content exceeds the space limit), the inquiry answer will be encrypted using the "symmetric encryption key of the user bridge recorded in the user bridge table of the SQLite database", and then the encrypted inquiry answer and reply time will be composed of a json data and written into the array of the json file of the question and answer content in the local outbox folder;

[0045] (f) After receiving a new record, the space master outbox decrypts the question and answer content in the record with "the symmetric encryption key of the user bridge where the outbox is located recorded in the user bridge table of the SQLite database", and then encrypts it with "the outgoing public key of the user bridge recorded in the user bridge table of the SQLite database where the outbox is located", and then writes the encrypted query content and query time into a json data array in the json file of the question and answer content in the space master outbox folder of the cloud user bridge;

[0046] (g) After the space owner's outbox in the cloud user bridge receives a new record, if the space owner's token value is greater than the token value consumed by the fan user for a single receipt and fan sending, and the fan's token value is greater than the token value consumed by the space owner's user for a single receipt and fan sending, then the record will be written into the array of the json file of the question and answer content in the fan inbox folder of the cloud user bridge. After writing, the record in the space owner's outbox in the cloud user bridge will be deleted, and the space owner's token value will be deducted by the token value consumed by the fan user for a single receipt and fan sending. The token value consumed by the space owner and the fan's token value will be deducted from the token value consumed by the space owner for a single receipt of a fan's message. These token values ​​are recorded in the non-relational database used to store user bridge information on the SIMKey manufacturer's server or the U-Shield manufacturer's server. If any of the conditions "the space owner's token value is greater than the token value consumed by the fan user for a single receipt of a fan's message" and "the fan's token value is greater than the token value consumed by the space owner for a single receipt of a fan's message" are not met, the AI ​​knowledge base will stop answering;

[0047] (k) When the fan successfully logs in to the SIMKey manufacturer's server or the U-Shield manufacturer's server, the fan takes out the record from the fan's inbox in the cloud user bridge, and decrypts the query answer of the record using "the fan's local user bridge corresponding to the cloud user bridge recorded in the user bridge table of the local SQLite database of the user bridge" and encrypts the query answer using "the symmetric encryption key of the user bridge recorded in the user bridge table of the SQLite database of the user bridge where the user bridge is located" to form a json data and write it together with the reply time into the array of the json file of the question and answer content in the inbox folder of the fan's local user bridge. After writing is completed, delete the record in the fan's inbox in the cloud user bridge;

[0048] (l) The fan uses the "symmetric encryption key of the user bridge recorded in the user bridge table of the SQLite database" to obtain the plain text of the answer to the query.

[0049] Furthermore, after the fan successfully logs in through the U shield terminal or SIMKey terminal, he can access the cloud user bridge between the space owner and the fan in the user space instance of the user where the AI ​​knowledge base is located to send and receive messages and set the fan terminal parameters of the user and access its AI knowledge base. The parameters that can be set by the fan terminal of the user bridge include: the token value consumed by the fan for a single receipt of a message from the space owner and the token value of the space owner;

[0050] After the space master successfully logs in through the U shield terminal or SIMKey terminal, he can access the user space instance of the user where the AI ​​knowledge base is located and all user bridges between the fans under the user space instance and set the space master end parameters of the user bridge to control the fans' access rights. Among them, the space master end of the user bridge can set the parameters including: the token value consumed by the space master user for a single receipt of a fan's sending and the token value of the fan;

[0051] The single receipt refers to receiving a single letter content, and the single letter content includes the question and answer time and the question and answer content encrypted by a key. Specifically, it refers to taking a record with the earliest time from the json file data of the sending content of the other party's outbox according to the order of sending time and which does not exist in the json file data of the receiving content of one's inbox and writing it into the json file of the receiving content of one's inbox; in this step, when the token value is greater than the token value consumed by a single receipt, it is automatically completed by the U-shield and SIMKey manufacturer social system. After completion, the token value is deducted from the token value consumed by a single receipt, and the record of the other party's outbox is deleted at the same time.

[0052] The present invention has the following beneficial effects:

[0053] 1. Through the social method provided by the present invention, the space owner can package all his original knowledge into an AI knowledge base at one time and publish it in the form of a cloud user space instance to attract fans' attention, and then earn income by selling tokens. At the same time, the original knowledge of the space owner is available but invisible, and is not easy to be pirated and copied. In addition, fans do not need to read articles or videos one by one to understand the information that the space owner wants to convey, which is more friendly to fans.

[0054] 2. Fans can achieve decentralized storage of personal social data through the social method provided by the present invention, without having to worry about not being able to confirm whether they have actually deleted their personal information or that their personal information has been leaked when they are not using it.

[0055] 3. Space owners and fans can encrypt and store personal social data through the social method provided by the present invention, and the encryption key is protected at the hardware level based on the U shield and SIMKey of real-name authentication. Even if a personal device is accidentally lost, the personal data security can be protected by reporting the loss to the operator in a timely manner. BRIEF DESCRIPTION OF THE DRAWINGS

[0064] The present invention provides a personal mobile decentralized AI social method based on U shield and SIMKey, including a space host, a SIMKey manufacturer service end or a U shield manufacturer service end and a fan end. The process is as follows: Figure 1 As shown, the following steps are included:

[0065] (1) The user purchases and registers a hardware device, performs initial configuration on the hardware device, and logs in to the hardware device; the hardware device includes a SIMKey terminal or a USB shield terminal, and the user includes a space owner and a fan;

[0066] (2) The space master builds an AI knowledge base based on the SIMkey or U shield and opens it to the outside world. The SIMKey manufacturer server or U shield manufacturer server creates a user space instance for the space master. At the same time, the space master builds a user space instance locally on the SIMkey or U shield.

[0067] (3) The fan accesses the address of the user space instance corresponding to the AI ​​knowledge base of the SIMKey manufacturer server or the U-Shield manufacturer server through the SIMkey terminal or the U-Shield terminal. After paying attention to the AI ​​knowledge base (address), the SIMKey manufacturer server or the U-Shield manufacturer server builds a cloud user bridge for the space owner and the fan. After the cloud user bridge is built, the space owner and the fan obtain their respective public and private keys for sending and receiving from the cloud user bridge, and then build their own local user bridges on the SIMkey terminal or the U-Shield terminal. After the local user bridge is built, the public and private keys for sending and receiving are deleted from the cloud user bridge, and a symmetric encryption key is randomly generated. The symmetric encryption key will be saved in the user bridge table of the local SQLite database. The user bridge table is used to encrypt the sending and receiving information of the cloud user bridge and save it to the local user bridge. The query record can be viewed locally later through this symmetric encryption key;

[0068] (4) Fans ask questions through the user bridge. The cloud user bridge of the SIMKey manufacturer server or the U shield manufacturer server forwards the questions to the local user bridge of the space owner. The AI ​​knowledge base of the SIMkey or U shield of the space owner responds to the questions and then forwards the answers to the fans through the cloud user bridge of the SIMKey manufacturer server and the U shield manufacturer server.

[0069] (5) If a fan cancels his / her subscription, the SIMKey manufacturer's server or the USB shield manufacturer's server will destroy the cloud user bridge between the fan and the space owner;

[0070] (6) The space owner cancels the opening of the AI ​​knowledge base to the outside world, and the SIMKey manufacturer's server or the U-Shield manufacturer's server destroys the cloud user space instance.

[0071] In the present invention, the SIMKey terminal or the USB shield terminal needs to be purchased and activated by real name.

[0072] In the present invention, the SIMKey terminal is a mobile client, which needs to be bound through a personal mobile phone number. The SIMkey is a special SIM card with stronger data security storage and identity authentication capabilities customized by the operator for users who have higher requirements for personal data security based on the ordinary SIM; the SIMkey includes an ordinary SIM card that can make calls, send text messages and surf the Internet, a SIMkey security algorithm, and a SIMkey password, and a secure storage area is constructed based on the SIMkey security algorithm and the SIMkey password to store the key of the SQLite database encrypted by SQLCipher.

[0073] In the present invention, the U shield is a PC client, which needs to be bound by a personal mobile phone number and needs to be inserted into a computer for use. The U shield includes a U disk, a private area and a public area. The U disk stores a personal knowledge base file module of the PC end, a personal intelligent knowledge base management software of the PC end and a SQLite database encrypted by SQLCipher on the PC end. The personal knowledge base file module of the PC end is used to store various types of personal knowledge bases, and the personal knowledge base file module of the PC end is backed up with the personal knowledge base file of the mobile phone end through the U shield or the cloud knowledge base. The personal intelligent knowledge base management software of the PC end is used to query, manage personal knowledge bases and call cloud resources. The private area of ​​the U disk stores the key of the SQLite database encrypted by SQLCipher, and the public area of ​​the U shield stores the boot program for entering the U disk and the initialization recovery program of the U shield.

[0074] In the present invention, the U-shield also includes a U-shield security algorithm area, a UKey and a U-shield password area. The U-shield security algorithm area is burned with the U-shield security authentication algorithm; the U-shield password is used to store the set U-shield password, and after the U-shield password is entered and verified correctly by the U-shield security authentication algorithm, the U-shield public area enters the U-shield private area and obtains the U-shield usage authority. The UKey is the device unique code of the U-shield set by the manufacturer.

[0075] In the present invention, the global framework diagram of the personal mobile decentralized AI social method based on U shield and SIMKey is as follows Figure 2 As shown, it can be seen that the space host end and fan end include the SIMKey end, the U shield end and the personal cloud.

[0076] In the present invention, the SIMKey terminal includes a mobile client app, a SQLite database encrypted by SQLCipher, a social space, a SIMKey secure storage area and a knowledge base file.

[0077] In the present invention, the U shield terminal includes PC client software, SQLite database encrypted by SQLCipher, social space, U shield private area, knowledge base file, thinking model and question and answer model.

[0078] In the present invention, the U-shield private area and the SIMKey secure storage area include the key of the SQLite database encrypted by SQLCipher.

[0079] In the present invention, the personal cloud includes a personal network disk, a git repository, a thinking model, a question-and-answer model, an SQLite database, and data located in a U-shield private area and a SIMkey secure storage area.

[0080] In the present invention, the SIMKey manufacturer server or the U-Shield manufacturer server includes a social space, a relational database, a non-relational database and an application.

[0081] In the present invention, the social space is a social space folder, under the social space folder is a user space folder, under the user space folder is a user space instance folder, the user space instance folder is a user bridge folder, the user bridge folder is a send and receive folder, under the send and receive folder is a json file of question and answer content, the data in the json file of question and answer content is a question and answer content array, the question and answer content array is a collection of question and answer records, each question and answer record contains the question and answer time and question and answer content, the question and answer content is encrypted with a key, so the social space is a collection of question and answer records between fans and space owners, used to store all encrypted question and answer data.

[0082] In the present invention, the social space is divided into a cloud social space and a local social space, the difference is: the question and answer content of the cloud social space is asymmetric encrypted, and the local question and answer content is symmetric encrypted; the user bridge of the cloud social space includes four types of inboxes, namely, fan outbox, fan inbox, space main outbox and space main inbox, and the user bridge of the local social space only includes personal outbox and personal inbox; the question and answer record under the outbox of the cloud social space will be deleted once it is confirmed to be taken away, and it is only a data transfer station, and the outbox of the local cloud social space is permanently stored locally by default as long as the user does not delete it.

[0083] In the present invention, the social space is subordinate to the user space, the user space is subordinate to the user space instance, and the user space instance is subordinate to the user bridge; the relational database includes a user table and a user space table; the non-relational database is used to store user bridge information; the application includes an authentication service and a space management service.

[0084] In the present invention, when a user logs in to a hardware device, the SIMKey manufacturer server or the U-Shield manufacturer server will perform triple verification of the user's identity through the authentication service of the application: the SMS verification code received by the mobile phone number, the user-defined password of the hardware device, and the unique identifier of the hardware device.

[0085] In the present invention, only when the triple-verification information is completely matched, can the user successfully log in to the hardware device: fans can access the user where the AI ​​knowledge base is located, the user space instance, and the user bridge between the space owner and the fans to send and receive messages and set relevant parameters (the token value consumed each time the fan receives a message from the space owner and the token value of the space owner) and access their AI knowledge base; space owners can access the user where the AI ​​knowledge base is located, the user space instance, and all user bridges between the fans and the user space instance and set relevant parameters (the token value consumed each time the space owner receives a message from a fan and the token value of the fan), thereby controlling the fan's access rights.

[0086] In the present invention, the AI ​​knowledge base includes a knowledge base file, a thinking model, a question-answering model and an inquiry template.

[0087] In the present invention, the thinking model is a general large model generated by data and computing power, such as openai or Wenxin Yiyan or Tongyi Qianwen; the question-and-answer model is used to connect the thinking model with the local personal knowledge base file, and provide an API for knowledge base upload, download and question-and-answer, such as AnythingLLM or QAnything or Qianfan; the inquiry template includes the template name, the corresponding knowledge base file, the address of the thinking model, the address of the question-and-answer model, the prompt word of the inquiry, the thinking model parameters and the question-and-answer model parameters; fans can ask questions that need to be asked through the inquiry template, and the inquiry template data is saved in the inquiry template table of the local SQLite database of the U-Shield and SIMKey.

[0088] In the present invention, the method for constructing the AI ​​knowledge base comprises the following steps:

[0089] The space owner creates a knowledge base file through the U-Shield or SIMKey terminal, then puts the knowledge base file into personal files, and transfers the knowledge base file to the local or cloud question and answer model through the question and answer model's API, and then sets the thinking model and inquiry template for the question and answer model to form an AI knowledge base and provide the ability to answer fans' questions.

[0090] In the present invention, the process of creating a user space instance of the space master by the SIMKey manufacturer server or the U shield manufacturer server is as follows: Figure 3 As shown, the specific steps are:

[0091] S101, after a user who is a space owner logs in to a hardware device server, a user name and a user instance space name are set;

[0092] S102, the hardware device server determines whether the name of the user instance space is unique and whether it is a real person space;

[0093] S103, the hardware device server creates a user instance space in the cloud and records it in a user space table of a cloud relational database;

[0094] S104, the hardware device server creates a user instance space in the space master locally and records it in the local SQLite database user space table;

[0095] S105, the hardware device server verifies again whether the user instance space is a real person space, and binds the AI ​​knowledge base for automatic receipt and automatic reply.

[0096] In the present invention, the user bridge includes a cloud user bridge and a local user bridge, and the user bridge is used to connect the AI ​​knowledge base of fans and space owners.

[0097] In the present invention, the access address of the user space instance in step (3) is {social domain name or IP address of the U-Shield and SIMKey manufacturer} / {user space name} / {user space instance name}.

[0098] In one embodiment of the present invention, the specific steps of setting the access rights of the user space instance are as follows:

[0099] Step S201, after the user logs in, access the user and digital avatar space address;

[0100] Step S202, comparing the current user by querying the user space table and the user table;

[0101] Step S203, when the current user is the space owner, the current user has the authority to manage all user bridges under the space; when the current user is a followed fan, the current user can enter the created user bridge to operate; when the current user is not following, he can choose whether to follow the space. If he chooses to follow the space, a user bridge will be created for it.

[0102] In the present invention, the access address of the cloud user bridge in step (3) is {social domain name or IP address of the U-Shield and SIMKey manufacturer} / {user space name} / {user space instance name} / {user bridge name}.

[0103] In one embodiment of the present invention, the specific steps of setting the access rights of the cloud user bridge include:

[0104] Step S301, after the current user logs in, accesses the target cloud user bridge address, queries the cloud user bridge information through the non-relational database, and determines the user identity;

[0105] Step S302: When the current user is the space master, the current user has the authority to manage the inbox and outbox of the user bridge space master, and has the authority to set the token value of the fan user and the token value consumed by each time the current user receives an email.

[0106] Step S303: When the current user is a fan user, the current user has the authority to manage the inbox and outbox of the user bridge space owner, and has the authority to set the token value of the space owner and the token value consumed by the current user each time he receives an email.

[0107] Step S304: When the current user is neither a main user of the space nor a fan user, he or she can choose whether to follow the space. If he or she chooses to follow the space, a user bridge is created for him or her.

[0108] In the present invention, the user space name is the user name set by the user of the U shield end and the SIMkey end when opening the social space on the U shield manufacturer server end and the SIMKey manufacturer server end, and is also the user space folder name. The name can be defined by the user and is stored in the user table of the relational database of the U shield manufacturer server end and the SIMKey manufacturer server end. A real-name mobile phone number can only have one user name and cannot be repeated with other users. Once registered, it is not allowed to be changed.

[0109] The user space instance name is the name taken when the user's AI knowledge base is open to the public. It is unique under the same user name and is also the user space instance folder. The name can be defined by the user. The user space instance name is stored in the user space table of the relational database of the U shield manufacturer server and the SIMKey manufacturer server.

[0110] In the present invention, the user bridge name is the user bridge folder name under the user space instance folder, which is unique under the same user space instance folder. Since the folder name is also the key in the non-relational database used to store user bridge information, it is also unique in the entire non-relational database that stores user bridge information. The name is a non-repeating unique value randomly generated by the U-Shield manufacturer server and the SIMKey manufacturer server.

[0111] In the present invention, the process of creating the user bridge is as follows: Figure 4 As shown, the specific steps are:

[0112] S401, after the space master user logs in to the hardware device server, he obtains his instance space address QR code, and the space master user provides the QR code to the fan user;

[0113] S402, after the fan user scans the QR code, a social space including an outbox and an inbox is generated for the space master user and the fan user respectively, and a public key of the outbox and inbox of the space master user is generated for the space master user, and a private key of the outbox and inbox of the fan user is generated for the fan user;

[0114] S403, storing the public key of the space owner and the private key of the fan user into a local SQLite database, and generating a symmetric key for each of the two parties, as well as a corresponding social space including an outbox and an inbox;

[0115] S404, the space master user and the fan user respectively initiate the deletion of public key and private key instructions to the cloud user bridge, and set the receiving thresholds of both parties, wherein the receiving threshold of the space master user is the token value of the fan user and the token value consumed each time the space master user's outbox is received, and the receiving threshold of the fan user is the token value of the space master user and the token value consumed each time the fan user's outbox is received.

[0116] In the present invention, in the step (4), the communication content of the fans' questions sent through the user bridge is end-to-end encrypted; the end-to-end encryption specifically means that from the time the fan starts asking the question to the time the fan receives the reply from the AI ​​knowledge base of the space owner, the message passes through 8 sending and receiving boxes, namely: the sending box and receiving box in the local user bridge between the fan and the space owner on the fan side; the fan sending box and receiving box in the cloud user bridge between the fan and the space owner, and the sending box and receiving box of the space owner; the sending box and receiving box in the local user bridge between the fan and the space owner on the space owner side.

[0117] In the present invention, the process of end-to-end encryption is as follows Figure 5 As shown, the specific steps include:

[0118] (a) The fan encrypts the inquiry content with the "symmetric encryption key of the user bridge recorded in the user bridge table of the SQLite database where the outbox is located", and then writes the encrypted inquiry content and inquiry time into a json data array in the json file of the question and answer content in the local outbox folder. The text length of the fan's inquiry content cannot exceed the space limit;

[0119] (b) After the fan-side outbox receives a new record, the question and answer content in the record is decrypted with "the symmetric encryption key of the user bridge recorded in the user bridge table of the SQLite database where the outbox is located", and then encrypted with "the outgoing public key of the user bridge recorded in the user bridge table of the SQLite database where the outbox is located", and then the encrypted inquiry content and inquiry time are combined into a json data and written into the array of the json file of the question and answer content in the fan outbox folder of the cloud user bridge;

[0120] (c) After the fan outbox in the cloud user bridge receives a new record, if the fan's token value is greater than the token value consumed by the space master user for a single fan outbox, the record will be written into the array of the json file of the question and answer content in the space master inbox folder of the cloud user bridge. After writing, the record in the fan outbox in the cloud user bridge will be deleted. At the same time, the fan's token value will be deducted from the token value consumed by the space master user for a single fan outbox. These token values ​​are recorded in the non-relational database used to store user bridge information on the SIMKey manufacturer's server or the U-Shield manufacturer's server;

[0121] (d) When the space master successfully logs in to the SIMKey manufacturer's server or the U-Shield manufacturer's server, the space master takes out the record from the space master's inbox in the cloud user bridge, and decrypts the inquiry content of the record using "the space master's local user bridge corresponding to the cloud user bridge, which records the user bridge's receiving private key in the user bridge table of the local SQLite database". If the text length of the inquiry content does not exceed the space master's quota limit, the inquiry content will be submitted to the AI ​​knowledge base corresponding to the user space instance of the parent user bridge. Otherwise, the inquiry content will not be submitted to the AI ​​knowledge base, and the answer to the inquiry with a text length exceeding the limit will be directly given. At the same time, the inquiry question will be encrypted using "the symmetric encryption key of the user bridge recorded in the user bridge table of the SQLite database of the user bridge where the user bridge is located" and together with the inquiry time, it will be written into an array of json data of the question and answer content in the inbox folder of the space master's local user bridge. After writing is completed, the record in the space master's inbox in the cloud user bridge will be deleted;

[0122] (e) After receiving the inquiry question, the AI ​​knowledge base will give the inquiry answer (if the inquiry answer is complex, the answer will be given in batches and if the token value of the fan is exhausted in the subsequent steps, the answer will be stopped). After receiving the inquiry answer (including the inquiry answer given when the text length of the inquiry content exceeds the space limit), the inquiry answer will be encrypted with the "symmetric encryption key of the user bridge recorded in the user bridge table of the SQLite database", and then the encrypted inquiry answer and reply time will be composed of a json data and written into the array of the json file of the question and answer content in the local outbox folder;

[0123] (f) After receiving a new record, the space master outbox decrypts the question and answer content in the record with "the symmetric encryption key of the user bridge where the outbox is located recorded in the user bridge table of the SQLite database", and then encrypts it with "the outgoing public key of the user bridge recorded in the user bridge table of the SQLite database where the outbox is located", and then writes the encrypted query content and query time into a json data array in the json file of the question and answer content in the space master outbox folder of the cloud user bridge;

[0124] (g) After the space master's outbox in the cloud user bridge receives a new record, if the space master's token value is greater than the token value consumed by the fan user for a single receipt and fan sending, and the fan's token value is greater than the token value consumed by the space master user for a single receipt and fan sending, then the record is written into the array of the json file of the question and answer content in the fan inbox folder of the cloud user bridge. After writing is completed, the record in the space master's outbox in the cloud user bridge is deleted. At the same time, the space master's token value will be deducted from the token value consumed by the fan user for a single receipt and fan sending, and the fan's token value will be deducted from the token value consumed by the space master user for a single receipt and fan sending. These token values ​​are recorded in the non-relational database of the SIMKey manufacturer server or the U-Shield manufacturer server for storing user bridge information. If any of the following conditions is not met: "the token value of the space owner is greater than the token value consumed by the fan user for a single receipt of a message" and "the token value of the fan is greater than the token value consumed by the space owner for a single receipt of a message" the AI ​​knowledge base will stop answering questions.

[0125] (k) When the fan successfully logs in to the SIMKey manufacturer's server or the U-Shield manufacturer's server, the fan takes out the record from the fan's inbox in the cloud user bridge, and decrypts the query answer of the record using "the fan's local user bridge corresponding to the cloud user bridge recorded in the user bridge table of the local SQLite database of the user bridge" and encrypts the query answer using "the symmetric encryption key of the user bridge recorded in the user bridge table of the SQLite database of the user bridge where the user bridge is located" to form a json data and write it together with the reply time into the array of the json file of the question and answer content in the inbox folder of the fan's local user bridge. After writing is completed, delete the record in the fan's inbox in the cloud user bridge;

[0126] (l) The fan uses the "symmetric encryption key of the user bridge recorded in the user bridge table of the SQLite database" to obtain the plain text of the answer to the query.

[0127] In the present invention, after the fan successfully logs in through the U shield or SIMKey end, he can access the cloud user bridge between the space owner and the fan in the user space instance of the user where the AI ​​knowledge base is located to send and receive emails and set the user's fan-end parameters and access its AI knowledge base. Among them, the fan-end parameters that can be set on the user bridge include: the token value consumed by the fan for a single receipt of an email from the space owner and the token value of the space owner.

[0128] In the present invention, the process of the reply process of the AI ​​knowledge base is as follows Figure 6 As shown, the specific steps are:

[0129] S501, after the fan user logs in to the hardware device server, he asks a question;

[0130] S502, the hardware device server enters the mobile phone APP or PC personal knowledge base management software console;

[0131] S503, the hardware device server obtains the key of the SQLite database encrypted by SQLCipher from the U-Shield private area or the SIMKey secure storage area, opens the SQLite database, and starts to collect the personal space and other people's space inbox information one by one to the local, and determines whether it is the real person space inbox information;

[0132] S504, if it is a real person space inbox message, the space owner himself replies;

[0133] S505, if it is not a real person space inbox message, the AI ​​knowledge base of the inquiry template corresponding to the digital avatar will reply.

[0134] In one embodiment of the present invention, the process of destroying a user space instance is as follows: Figure 7 As shown, the specific steps are:

[0135] S601, after logging in, the user initiates a request to the hardware device server to destroy the user space instance;

[0136] S602, the hardware device server deletes the user space instance, all user bridges of the user, and all files in the knowledge base folder;

[0137] S603, deleting the user bridge data related to the user space instance from the non-relational database, and deleting the user space table data of the user from the relational database.

[0138] In one embodiment of the present invention, the process of destroying a user bridge is as follows: Figure 8 As shown, the specific steps are:

[0139] S701, after the space master user initiates the destruction of the user bridge, the hardware device server destroys the user bridge social space;

[0140] S702, destroying the local user bridge public key and private key of the space master user and the fan user respectively;

[0141] S703, deleting the user bridge related data from the non-relational database, and deleting the fan user's data from the user space table of the relational database.

[0142] It can be seen from the above embodiments that the present invention provides a personal mobile decentralized AI social method based on U shield and SIMKey, including a space master end, a SIMKey manufacturer service end or a U shield manufacturer service end and a fan end, including the following steps: activating the login hardware device-building an AI knowledge base and creating a user space instance-fans follow the user space instance-building a user bridge-fans ask questions through the user bridge-fans cancel the attention, and the cloud user bridge is destroyed-the space master cancels the opening of the AI ​​knowledge base to the outside world, and the user space instance is destroyed. Through the social method provided by the present invention, the space owner can package all of his original knowledge into an AI knowledge base at one time and publish it in the form of a cloud user space instance to attract fans' attention, and then he can obtain income by selling tokens. At the same time, the original knowledge of the space owner is available but invisible, and it is not easy to be pirated and copied. In addition, fans do not need to read articles or videos one by one to understand the information that the space owner wants to convey, which is more friendly to fans. Fans can realize the decentralized storage of personal social data through the social method provided by the present invention, without worrying about not being able to confirm whether they have really deleted personal information or the problem of personal information being leaked when they are not using it. Space owners and fans can encrypt and store personal social data through the social method provided by the present invention, and the encryption key is protected at the hardware level based on the U shield and SIMKey of real-name authentication. Even if a personal device is accidentally lost, personal data security can be protected by reporting the loss to the operator in a timely manner.
