[0062] The technical solution of the present invention is further described in detail below through the accompanying drawings and embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

Together with the embodiments of the present invention, they are used to explain the present invention and do not constitute a limitation of the present invention. In the accompanying drawings:

[0066] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0067] The embodiment of the present invention provides a data storage method for a smart education platform, such as Figure 1 As shown, including:

[0068] Step S1: after receiving the data storage instruction from the user, output a verification request;

[0069] Step S2: receiving verification information input by the user through the smart pen based on the verification request;

[0070] Step S3: Verify the verification information. When the verification passes, parse the data storage instruction and obtain the target storage area.

[0071] Step S4: obtaining the authority requirement of the target storage area, and when the user authority of the user satisfies the authority requirement, storing the data corresponding to the data storage instruction into the target storage area.

[0072] The working principle and beneficial effects of the above technical solution are:

[0073] In the big data environment, there will inevitably be a large number of application scenarios for data aggregation and storage. Large amounts of data aggregation and storage will bring greater data security risks. Therefore, on the basis of the original storage environment and network security, it is necessary to strengthen the security of the data itself, and add big data encryption, big data desensitization, and big data auditing to ensure data storage security. In addition, when the user issues a data storage instruction, the smart education platform requires the user to verify the identity. The verification method is to use the smart pen input method. After the verification is passed, it is also necessary to determine whether the user has the permission to store the target storage area based on the user's permissions. Only when the user has the permission can the storage be performed; by verifying the identity and permissions, the data storage is managed and controlled, and the data of the smart education platform is stored securely.

[0074] In one embodiment, the data storage method of the smart education platform further includes:

[0075] Step S5: When the user's authority does not meet the authority requirements, the data corresponding to the data storage instruction is stored in the public storage area; the data stored in the public storage area is subject to verification by other users.

[0076] Step S6: receiving a recommendation instruction from other users for storing data, retrieving the recommendation authority of other users, and sending a storage request to the target storage area again in combination with the user authority of the data user; when the storage request is approved, storing the data in the target storage area;

[0077] Step S7: start timing from the storage of data in the public storage area. When a preset time period has passed and no other user has recommended the data, the data is deleted.

[0078] The working principle and beneficial effects of the above technical solution are:

[0079] In order to prevent users from not having sufficient permissions and thus causing useful data to not be stored on the smart education platform, the public storage area is used for temporary storage. During temporary storage, verification and recommendation from other users are accepted. When the total number of recommended other users reaches the preset total number, or the preset public announcement time is reached, another data storage request is made. When approved, the data is stored in the target storage area. After the public announcement period, data that has not yet been recommended will be deleted to release the public storage area.

[0080] In one embodiment, in step 3, verifying the verification information includes:

[0081] The verification information is matched with the verification information in the verification database. When the match is consistent, the verification is passed;

[0082] Among them, the verification library is established in advance, and the steps for establishing the verification library are as follows:

[0083] When a user registers, a preset number of verification words are extracted from a preset standard library and displayed to the user; the user writes the verification words multiple times using the smart pen;

[0084] Sampling the verification word written by the user to determine the stroke order of the verification word and the writing force and writing time of each stroke in the stroke order;

[0085] The verification character, stroke order, writing force and writing time are used as verification information in the verification library.

[0086] The working principle and beneficial effects of the above technical solution are:

[0087] The verification code written by the user when registering is the basis for establishing the verification database. It is relatively representative and inquires about the user's identity during the user's access process. It can effectively track the user's access and improve the security of data storage.

[0088] In one embodiment, the writing force is determined as follows:

[0089]

[0090] In the formula, F k is the writing strength of the k-th stroke written by the user in the determined verification library; n is the total number of times the user writes the verification word; f i，k is the writing force of the kth stroke when the user writes the verification word for the i-th time, f j，k is the writing force of the kth stroke when the user writes the verification word for the jth time; when the writing force of the kth stroke falls within The probability is greater than When , m takes the value of 1, otherwise, it takes the value of 0; γ is the preset first correction coefficient;

[0091] The writing time is determined as follows:

[0092]

[0093] Where, T k is the writing time of the k-th stroke written by the user in the determined verification library; t i，k is the writing time of the kth stroke when the user writes the verification word for the i-th time, t j，k is the writing time of the kth stroke when the user writes the verification word for the jth time; when the writing time of the kth stroke falls within The probability is greater than When , M takes the value of 1, otherwise, it takes the value of 0; θ is the preset second correction coefficient.

[0094] The working principle and beneficial effects of the above technical solution are:

[0095] By extracting writing force and writing time based on a certain amount of data, a benchmark based on writing force and writing time is established to ensure the accuracy of the benchmark, thereby improving the accuracy of the verification. During the verification, the similarity between the benchmark and the data in the currently input verification information can be used as a judgment of whether the verification has passed. When the similarity is greater than the preset judgment value, the verification has passed. In addition, the judgment threshold can be further determined based on the first information and the second information on the basis of the benchmark. The threshold can be half of the maximum deviation of the writing force or writing time, that is, the data in the currently input verification information differs from the benchmark within the threshold range, and the verification has passed.

[0096] In one embodiment, in step S6, the recommendation permissions of other users are retrieved, and combined with the user permissions of the user of the data, a storage request is sent to the target storage area again, including:

[0097] Obtain the first permission utility coefficient corresponding to the recommended permission of other users;

[0098] Obtaining a second permission utility coefficient corresponding to the user permission;

[0099] The permission value of the storage request is determined based on the recommended permission, the user permission, the first permission utility coefficient and the second permission utility coefficient; the calculation formula of the permission value is as follows:

[0102] The working principle and beneficial effects of the above technical solution are:

[0103] This real-time example is a method for determining permission values. The determination of permission values ​​provides a basis for passing requests for data to be sent again. The permission values ​​are determined by recommending users and the user's own user permissions. After the data is verified by many people and determined to be useful data, they are jointly recommended to provide a storage method for useful data.

[0104] In one embodiment, the data storage method of the smart education platform further includes:

[0105] When the storage request is approved, the first permission utility coefficient of other users who made the recommendation is increased;

[0106] When the storage request is not approved, the first permission utility coefficient of other users who made the recommendation is lowered;

[0107] Among them, the following formula is used for adjustment when adjusting upward and downward:

[0108]

[0109] Among them, γ′ represents the adjusted authority utility coefficient, γ represents the authority utility coefficient before adjustment; c represents the correction factor determined by whether the storage request is passed. When the storage request is passed, c is a positive value, and when the storage request is not passed, c is a negative value. Indicates the adjustment amplitude, Indicates the correction value of the adjustment amplitude; d h Indicates the recommendation authority of other users for the hth recommendation.

[0110] The working principle and beneficial effects of the above technical solution are:

[0111] When the result of the data storage request comes out, the first permission utility coefficient of other recommended users is adjusted to improve the accuracy of the subsequent confirmation of the permission value of the storage request.

[0112] In one embodiment, after step S5, the method further includes:

[0113] Step S51: Obtain verification information of data from other users;

[0114] Step S52: when the total amount of verification information is greater than a preset credibility judgment execution threshold, the credibility of the data is determined based on the verification information, and when the credibility is lower than the preset threshold, the data is deleted;

[0115] Wherein, step S52: determining the credibility of the data based on the verification information includes:

[0116] Obtain a preset verification information parsing template, and quantify the verification information to obtain a verification value;

[0117] Determine the ratio of the verification information that has passed the verification to the total number of verification information;

[0118] Based on the proportion value and the verification value, the credibility of the data is determined. The calculation formula is as follows:

[0119]

[0120] Among them, y is the credibility, σ is the preset weight; ρ is the proportion value; E q is the checksum value of the qth other user; q is the preset utility coefficient of the qth other user.

[0121] The working principle and beneficial effects of the above technical solution are:

[0122] Through the verification information of other users, the data is analyzed to see whether it is credible. If it is not credible, the data is deleted to ensure the security of data storage.

[0128] The working principle and beneficial effects of the above technical solution are:

[0129] When a user issues a data storage instruction, the smart education platform requires the user to verify his or her identity. The verification method is to use a smart pen input method. After the verification is passed, it is also necessary to determine whether the user has the permission to store the target storage area based on the user's permissions. Storage can only be performed when the user has the permission. By verifying the identity and permissions, data storage is managed and controlled, realizing the secure storage of data on the smart education platform.

[0135] In order to prevent users from not having sufficient permissions and thus causing useful data to not be stored on the smart education platform, the public storage area is used for temporary storage. During temporary storage, verification and recommendation from other users are accepted. When the total number of recommended other users reaches the preset total number, or the preset public announcement time is reached, another data storage request is made. When approved, the data is stored in the target storage area. After the public announcement period, data that has not yet been recommended will be deleted to release the public storage area.
