Description

Technical Field

[0001] A data sharing platform related to the present invention, in particular, a data security sharing platform based on artificial intelligence applied to the field of electronic digital data processing. Background Art

[0002] Data sharing can reasonably achieve resource allocation, save social costs, and create more wealth. It is an important means to improve the utilization rate of data resources and avoid repeated waste in data collection, storage, and management.

[0003] The specification of Chinese Patent CN112257047B discloses a security control method, device, equipment, and medium for a data sharing platform. The method includes: receiving a data call request sent by a third-party user; wherein, the data call request includes a user identity identifier, user signature data, and first verification information; determining the user password information corresponding to the user identity identifier; generating second verification information using the user password information and the user signature data; and when the first verification information matches the second verification information, returning target data for the data call request to the third-party user. Through the embodiments of the present invention, the security control of the data sharing platform is optimized. By improving the identity authentication mechanism for requests during data calls, the security control ability of the data sharing platform is improved, and the security and consistency of data transmission are ensured.

[0004] The specification of Chinese Patent CN112783847B discloses a data sharing method and device. The data sharing method includes: obtaining encrypted data to be analyzed in a data sharing platform selected by a data user; decrypting the encrypted data to be analyzed using a trusted execution program and performing data analysis on the decrypted data to obtain a data analysis result of the encrypted data to be analyzed. The trusted execution program has built-in identity authentication information of the data user, and the execution process of the trusted execution program is invisible to the data user, which can ensure the security of shared data during the data sharing process and improve the data analysis efficiency.

[0005] Although data sharing provides data resources for users, to ensure data security, users need to perform identity authentication (including identity information, face recognition, etc.) when accessing data, which is convenient for tracing in case of data security problems in the later stage. However, for special groups in society, such as those with speech function disorders and text recognition disorders, due to certain operation obstacles, if identity authentication is required for each access, there will be great inconvenience in use. Therefore, how to design a sharing platform with a convenient and secure login method for special groups is an urgent problem to be improved. Summary of the Invention

[0006] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is how to simplify the operation of special groups accessing the data sharing platform on the basis of effectively ensuring data security.

[0007] To solve the above problems, the present invention provides an artificial intelligence-based data security sharing platform, including a terminal platform and a verification medium connected to the terminal platform. The terminal platform includes a transmission module, a dual determination module, an identity authentication module, a feature recognition module, a fictionalization module, a reading module, and a quick verification module. The login module is connected to a historical database, and the historical database is used to store the user name information with login history and its corresponding user identity information.

[0008] The transmission module is used to receive the data transmitted by the verification medium and transmit data to the verification medium. The dual determination module is used to determine whether the user name is the first login and determine whether the user belongs to a special group according to the input method of the user name.

[0009] During the process of the user accessing the data of the terminal platform, the feature recognition module performs feature recognition and extraction on the accessed data. The fictionalization module performs false reconstruction on the data accessed by the user to generate a data verification package with missing features, and transmits the data verification package to the verification medium for storage through the transmission module. The quick verification module is used to perform a multiple-choice question and answer verification process for special groups.

[0010] The verification medium includes a data storage module, and the data storage module is used for a single user name, a single special input method, and multiple data verification packages with missing features.

[0011] An access method for an artificial intelligence-based data security sharing platform includes the following steps:

[0012] S1. The user connects to the server through the verification medium and accesses and logs in to the terminal platform.

[0013] S2. Manually input a unique user name, and judge whether it is a new user according to the access history of the user name. At the same time, judge whether the user belongs to a special group according to the input method of the user.

[0014] S2.1. When the user name has no access history but the input method is a special input method, it is determined that the user name belongs to a new user of a special group. At this time, the user is authenticated. After successful authentication, the user can access the data of the terminal platform. At the same time, the verification medium records the user name and the input method, which are respectively recorded as the historical user name and the old special input method W.

[0015] During the access process, the terminal platform regularly generates a data verification package with missing features according to the user's access content and data, and transmits it to the verification medium for storage.

[0016] S2.2. When the user name corresponds to the historical user name of the verification medium and the input method is the same as the old special input method W, it is determined that the user name belongs to an old user of a special group. At this time, the terminal platform automatically obtains all data verification packages in the verification medium and conducts a multiple-choice question and answer verification on the user. After successful verification, the user can access the data of the terminal platform;

[0017] During the access process, the terminal platform regularly generates a data verification package with missing features based on the user's access content and data, and transmits it to the verification medium for storage;

[0018] S2.3. When the user input method is the general input method and the old special input method W is not recorded in the verification medium, it is determined that the user name belongs to the general population. At this time, the user is authenticated, and after successful authentication, the user can access the data of the terminal platform.

[0019] As a further supplement to this application, the generation process of the data verification package with missing features in steps S2.1 and S2.2 is specifically as follows: The terminal platform first identifies the key features in the data according to the data content accessed by the user, and then uses false data to replace the key features, and combines them with the unchanged data to form a data verification package with missing features.

[0020] As a further supplement to this application, the multiple-choice question and answer verification process in step S2.2 is specifically as follows: According to the content of the data verification package in the verification medium, a data text F related to it is generated, and the data text F and multiple other randomly generated data texts unrelated to the data verification package are displayed to the user together. When the user correctly selects the data text F, the verification is successful; otherwise, the verification fails, and the user has no right to access the terminal platform.

[0021] As a further supplement to this application, the identity authentication process in steps S2.1 and S2.3 is specifically as follows: The user first enters his own real information on the terminal platform, including name and identity document information. After being verified correctly by the identity authentication module, face recognition is performed, and after successful recognition, the authentication is successful.

[0022] As a further supplement to this application, when any of the following two conditions is met, the terminal platform performs hidden leakage prevention processing: Condition 1: When the input method is the special input method but is different from the old special input method W; Condition 2: When the input method is the special input method but the user name does not correspond to the historical user name of the verification medium.

[0023] As a further supplement to the present application, the hidden anti-leakage processing includes the following operations: the terminal platform sends an abnormal access alarm to the background monitoring terminal. At the same time, the authentication information is displayed on the terminal platform, and all the feature-missing data verification packages in the verification medium are obtained through the reading module. When illegal elements access the data, the corresponding feature-missing data verification packages are selected to be displayed to them, so as to avoid alerting the illegal elements and delay time without disclosing the real data.

[0024] As another improvement of the present application, the verification medium includes a medium body, which is electrically connected to a plug through a transmission line, and a panel and a camera are fixedly connected to one end of the medium body away from the transmission line. An inner cavity is opened inside the medium body, and an electric slide rail and a fixed plate are fixedly connected inside the inner cavity. The electric slide rail includes a guide rail and a slide seat that are slidably connected to each other, a moving contact is fixedly connected to the outer end of the slide seat, a guide plate is fixedly connected to one end of the fixed plate away from the slide seat, the guide plate is electrically connected to the transmission line, and a plurality of static contacts are fixedly connected to one end of the fixed plate close to the slide seat, and a breakable conductor is electrically connected between the static contact and the guide plate.

[0025] As another improved supplement of the present application, the breakable conductor includes a wire having one end electrically connected to the guide piece, a fuse is electrically connected between the wire and the stationary contact, and an outer end of the fuse is wound around and in contact with a heating wire.

[0026] As another improved supplement of the present application, the verification medium also includes a multi-mode transmission module, an image acquisition and recognition module, an operation module and a secondary anti-leakage module. The panel is electrically connected to the operation module, the camera is electrically connected to the image acquisition and recognition module, the electric slide rail is electrically connected to the multi-mode transmission module, and the heating wire is electrically connected to the secondary anti-leakage module.

[0027] To sum up, the present application adopts verification media as the only external tool for logging into the terminal platform. During the process of special groups accessing the terminal platform, the verification media records the unique user name of the special groups, the special input method, and the data verification package with missing features generated based on the access content. In the later process of the special groups logging into the terminal platform for non-first time, multiple-choice questions are generated according to the data verification package, and question-and-answer verification is performed on the special groups, thereby replacing the existing identity authentication operation. On the basis of effectively ensuring data security, a low-barrier operation method is provided for special groups, while also reducing the risk of information exposure and improving friendliness to special groups. When the user name or the special input method used does not match the record in the verification medium, the terminal platform obtains the data verification package with missing features in the verification medium while making a remote alarm, and displays a false display to the user, which effectively maintains data security while not easily alerting illegal elements.

[0039] The following will describe the two embodiments of the present application in detail with reference to the accompanying drawings.

[0040] The first embodiment:

[0041] The present invention provides an artificial intelligence-based data security sharing platform. Please refer to Figure 1, including a terminal platform storing a large amount of shared data and a verification medium connected to the terminal platform. The terminal platform includes a transmission module, a dual determination module, an identity authentication module, a feature recognition module, a fictionalization module, a reading module, and a quick verification module. The login module is connected to a historical database, which is used to store the user name information with login history and its corresponding user identity information, and each user name is unique and cannot be repeated.

[0042] The transmission module is used to receive data transmitted by the verification medium and transmit data to the verification medium. The dual determination module is used to determine whether the user name is logged in for the first time and determine whether the user belongs to a special group according to the input method of the user name. Specifically: if the user name is different from all user name information in the historical database, it is determined as a new user. If it is the same as one of the user name information and the same as the user name recorded in the verification medium, it is determined as an old user. In this embodiment, the text input method and the voice input method are set as general input methods, and users using these two methods are general users. The lip language input method and the sign language input method are set as special input methods, and users using these two methods belong to special groups.

[0043] During the process of the user accessing the data of the terminal platform, the feature recognition module performs feature recognition and extraction on the accessed data. The fictionalization module performs false reconstruction on the data accessed by the user to generate a data verification package with missing features, and transmits the data verification package to the verification medium for storage through the transmission module. The quick verification module is used to perform a multiple-choice question and answer verification process for special groups.

[0044] The verification medium includes a data storage module, which is used for a single user name, a single special input method, and multiple data verification packages with missing features.

[0045] Combined Figure 2 As shown, a data security sharing platform based on artificial intelligence, whose access method includes the following steps:

[0046] S1. The user connects to the server through the verification medium and accesses and logs in to the terminal platform;

[0047] The USB connection method can be adopted between the verification medium and the server. The verification medium is the only external tool for logging in to the terminal platform, and its function is similar to that of a USB key;

[0048] S2. Manually input a unique user name, and judge whether it is a new user according to the access history of the user name, and at the same time judge whether the user belongs to a special group according to the input method of the user;

[0049] S2.1. When the username has no access history but the input method is a special input method, it is determined that the username belongs to a new user of a special group. At this time, the user is authenticated. After successful authentication, the user can access the data on the terminal platform. At the same time, the verification medium records the username and the input method, which are respectively recorded as the historical username and the old special input method W;

[0050] During the access process, the terminal platform regularly generates a data verification package with missing features based on the user's access content and data, and transmits it to the verification medium for storage;

[0051] S2.2. When the username corresponds to the historical username in the verification medium and the input method is the same as the old special input method W, it is determined that the username belongs to an old user of a special group. At this time, the terminal platform automatically obtains all the data verification packages in the verification medium and conducts a multiple-choice question and answer verification on the user. After successful verification, the user can access the data on the terminal platform;

[0052] During the access process, the terminal platform regularly generates a data verification package with missing features based on the user's access content and data, and transmits it to the verification medium for storage;

[0053] Since the data verification package is generated based on the previous access data during the previous access process of the special group, the data verification package is closely related to the special user. Using the data verification package as the basis for the multiple-choice question and answer verification not only simplifies the authentication process of the special user, but also has high security and accuracy. When the user is unaware of the previous access process and access data, the success rate of the multiple-choice question and answer verification process is relatively low. Combining the two conditions of the username and the input method, even if other users steal the verification medium, it is difficult to successfully log in to the terminal platform without knowing the information such as the username, special input method, and data verification package corresponding to the verification medium, effectively protecting the data security of the terminal platform;

[0054] From the combination of steps S2.1 and S2.2, it can be seen that when a special population needs to log in to the terminal platform, identity authentication is required for the first login (the identity authentication process will be described in detail below). This operation is to effectively record and verify the identity information of the user, confirm the security of the personnel identity, and thus provide basic security protection for the data of the terminal platform. When the special population already has a login history and logs in later, identity authentication is not required. As long as the answers to the multiple-choice questions are correct during the question-and-answer verification process, the login can be completed. Therefore, for the process of the special population logging in to the terminal platform for the non-first time, this application adopts a simple and convenient multiple-choice question-and-answer verification operation with data relevance to replace the existing identity authentication operation. On the basis of effectively ensuring data security, it provides a low-barrier operation method for the special population and improves the friendliness to the special population.

[0055] S2.3. When the user input method is the general input method and the old special input method W is not recorded in the verification medium, it is determined that the user name belongs to the general population. At this time, the user is subjected to identity authentication. After successful authentication, the data of the terminal platform can be accessed.

[0056] If the old special input method W is not recorded in the verification medium, it indicates that the verification medium has not been used by the special population. At this time, if the user input method is the general input method, whether it is a new user or an old user, the identity authentication method is used for login, effectively improving the data security of the terminal platform.

[0057] The generation process of the data verification package with missing features in steps S2.1 and S2.2 is as follows: The terminal platform first identifies the key features in the data according to the data content accessed by the user, and then uses false data to replace the key features, and combines it with the unchanged data to form a data verification package with missing features.

[0058] On the one hand, the data verification package with missing features can be used as the basis for the multiple-choice question-and-answer verification process in step S2.2. On the other hand, when the verification medium is stolen by illegal elements, even if the illegal elements steal the data verification package from the verification medium, since the key features in the data verification package have been replaced by false data, it is difficult for the illegal elements to obtain the real data, thus further ensuring the security of the data. Supplementary description: After the user successfully verifies on the terminal platform, during the process of accessing data, the user can view, delete, etc. the data verification package in the verification medium. When the storage space of the verification medium is insufficient, the data verification package with a long storage time and no obvious access memory can be deleted, which can effectively restore the storage space of the verification medium and is not likely to have an obvious impact on the subsequent question-and-answer verification process.

[0059] The multiple-choice question answering verification process in step S2.2 is as follows: According to the content of the data verification package in the verification medium, a data text F related to it is generated. The data text F and multiple other randomly generated data texts unrelated to the data verification package are presented to the user. When the user correctly selects the data text F, the verification is successful; otherwise, the verification fails, and the user has no right to access the terminal platform. Supplementary note: The data text F should be as concise as possible and does not involve the specific content of the data. It only needs to indicate the data type. Here, for the convenience of those skilled in the art to understand, the following example is given: Suppose the data verification package in the verification medium is related to finance. Then the data text F can be "financial market", "financial analysis", "investment fund", etc., and the other randomly generated data texts are content unrelated to finance, such as "real estate", "land lease", etc.

[0060] The identity authentication process in step S2.1 and step S2.3 is as follows: The user first enters their own real information on the terminal platform, including name, identity document information, mobile terminal information, etc. After being verified correctly by the identity authentication module, face recognition is performed. If the recognition is successful, the authentication is successful. In the above identity authentication process, since there is a large amount of information input, it is not very user-friendly for special groups. It not only takes a long time for special groups to log in, but also there is a risk of information exposure and being known by others during their use of special input methods (the sign language input actions will be exposed to the outside, and lip language expressions are also easily visually detected by others). Therefore, this application uses a simple multiple-choice question answering verification method, a low-barrier and low-risk operation method, as a replacement, effectively improving the friendliness to special groups.

[0061] When any of the following two conditions is met, the terminal platform performs hidden leakage prevention processing: Condition 1: When the input method is a special input method but is different from the old special input method W; Condition 2: When the input method is a special input method but the user name does not correspond to the historical user name of the verification medium. To a certain extent, both of the above situations indicate that the verification medium may have been stolen by others.

[0062] The hidden leakage prevention processing includes the following operations: The terminal platform sends an abnormal access alarm to the background monitoring terminal. At the same time, the information of successful authentication is displayed on the terminal platform, and all the data verification packages with missing features in the verification medium are obtained through the reading module. When an illegal person accesses the data, the corresponding data verification package with missing features is selected and shown to them, so as to achieve the goal of not disclosing the real data, not alarming the illegal person, and delaying time.

[0063] Please refer to Figure 3, the verification medium includes a medium body 1. The medium body 1 is electrically connected to a plug 3 through a transmission line 2. The plug 3 is used for hardware connection with a server, making the medium body 1 an external tool for logging in to the terminal platform. One end of the medium body 1 away from the transmission line 2 is fixedly connected to a panel 4 and a camera 5. The verification medium also includes an image acquisition and recognition module and an operation module. The panel 4 is electrically connected to the operation module, and the camera 5 is electrically connected to the image acquisition and recognition module. General users can use the panel 4 for touch screen operations to achieve text input or voice input of content. The camera 5 is used for image acquisition and recognition of special populations, including image acquisition and recognition during lip language input and image acquisition and recognition during sign language input. After recognition, the sign language or lip language content is converted into text form and displayed on the panel 4. After the personnel confirm it, both the original image information and the converted text information are transmitted to the terminal platform. The original image information can be used by the terminal platform for comparison and judgment of the input method, and the text information is used to intuitively display the content input by the user to the terminal platform.

[0064] The second implementation method:

[0065] Based on the first implementation method, this implementation method further sets the structure of the verification medium as follows: Please refer to Figure 4 and Figure 5 , a cavity 101 is opened inside the medium body 1. An electric slide rail and a fixed plate 7 are fixedly connected inside the cavity 101. The electric slide rail includes a guide rail 61 and a slide seat 62 that are slidably connected to each other. The outer end of the slide seat 62 is fixedly connected to a moving contact 10. One end of the fixed plate 7 away from the slide seat 62 is fixedly connected to a guide piece 8. The guide piece 8 is electrically connected to the transmission line 2. One end of the fixed plate 7 close to the slide seat 62 is fixedly connected to a plurality of static contacts 9. A breakable conductor 11 is electrically connected between the static contact 9 and the guide piece 8. When the moving contact 10 fits with a certain static contact 9, a circuit connection is achieved between the moving contact 10, the static contact 9, the breakable conductor 11, and the guide piece 8. The data on the medium body 1 can be transmitted to the server through the transmission line 2 and the plug 3. Please refer to Figure 6 , the breakable conductor 11 includes a wire 1101 electrically connected to the guide piece 8 at one end. A fuse 1102 is electrically connected between the wire 1101 and the static contact 9. The fuse 1102 can be made of low melting point conductive materials such as lead and lead alloys. The outer end of the fuse 1102 is wound and contacted with a heating wire 12. The verification medium also includes a multi-mode transmission module and a secondary anti-leakage module. The electric slide rail is electrically connected to the multi-mode transmission module, and the heating wire 12 is electrically connected to the secondary anti-leakage module.

[0066] In this embodiment, by providing a plurality of static contacts 9 and making them correspond to different input methods respectively. For example, in Embodiment 1, four input methods are provided, so four static contacts 9 are also provided, namely Connector 1 (corresponding to the text input method), Connector 2 (corresponding to the voice input method), Connector 3 (corresponding to the lip-reading input method), and Connector 4 (corresponding to the sign language input method). Combining Figure 7 As shown, when the user uses text input on the media body 1, after the multimode transmission module recognizes this input method, it starts the electric slide rail to move the moving contact 10 to fit with Connector 1, so as to transmit the text content to the terminal platform. When the user uses lip-reading input on the media body 1, after the multimode transmission module recognizes this input method, it starts the electric slide rail to move the moving contact 10 to fit with Connector 3, so as to transmit the lip-reading image and the recognized text content to the terminal platform together; when the disconnectable conductor 11 connected to a certain static contact 9 is disconnected, even if the moving contact 10 fits and communicates with this static contact 9, it is difficult to realize the transmission of corresponding data.

[0067] When one of the prerequisite conditions for the hidden anti-leakage process occurs, it indicates that there is a possibility that the verification medium has been stolen by others. Although the terminal platform has performed the hidden anti-leakage process operation at this time, it is difficult to ensure the successful pursuit of the illegal user, and there is a situation where the illegal user carries the verification medium and escapes. Therefore, to reduce the success probability of the secondary use of this verification medium, the following operations are performed during the user's this operation: According to the user's input method, the moving contact 10 will move to the position of the corresponding static contact 9 and conduct electrical connection with it. At this time, combining Figure 8 and Figure 9 As shown, the heating wire 12 outside the disconnectable conductor 11 connected to the remaining static contacts 9 is started through the secondary anti-leakage module. After the heating wire 12 is heated, it melts the melt 1102 ( Figure 9 where n represents the melted melt 1102 in ), so that the circuit connection between the wire 1101 and the static contact 9 is disconnected, and then the remaining static contacts 9 all lose the data transmission function, while the static contact 9 that is currently connected to the moving contact 10 remains in normal use. In this way, it is not easy to alarm the illegal elements. Through the above operations, when used secondly later, when the illegal user finds that his input method is different from the old special input method W in the verification medium, it is also difficult to connect the circuit connection of the corresponding static contact 9 to transmit the content, and when the user changes the usage method, "This input method recognition is incorrect. It is recommended to change the input method" is displayed on the panel 4 to confuse the user and make it difficult for him to be alert. However, at the same time, due to the difficulty of matching the input method, it is difficult to successfully verify, effectively reducing the success probability of the secondary use of this verification medium and further protecting the data security of the terminal platform.

[0068] Combined with the current actual requirements, the above-mentioned implementation manner adopted in this application, the protection scope is not limited thereto. Within the scope of knowledge possessed by those skilled in the art, various changes made without departing from the concept of this application still fall within the protection scope of the present invention.
