[0045] The following will explain in detail how to improve the security of data in the online resource library in conjunction with specific embodiments and drawings.

[0046] Embodiment 1

[0047] See also Figure 1 , shown is a data management method for an online resource library in a first embodiment of the present invention, which is used to manage data in an online resource library. The online resource library includes a plurality of sub-resource libraries divided according to data security levels, wherein each sub-resource library of a different security level is configured with an original encryption chain, and the method includes steps S10~S14.

[0048] Step S10, obtaining the security level of the uploaded data to be uploaded to the online resource library, and determining the target sub-resource library to which the uploaded data belongs from among the multiple sub-resource libraries according to the security level.

[0049] Among them, the online resource library is divided into multiple sub-resource libraries with different security levels according to different security levels. Each sub-resource library stores data with the same security level. For example, the security level requirements of the data can be divided into different security levels such as low security level, general security level and high security level. In practice, data will be uploaded to the online resource library from time to time to update the data in the online resource library. Therefore, after obtaining the uploaded data to be uploaded, its corresponding security level can be determined, and then the target sub-resource library where the data needs to be stored can be determined to achieve a reasonable classification of data storage. In specific implementation, the security level of the data can be actively calibrated before uploading the data. In addition, on the existing basis, different access permissions can be set after setting sub-resource libraries with different security levels. Only specific accounts or users can access data that requires a higher security level, thereby achieving security redundancy.

[0050] Step S11, obtaining the uploaded data of the same security level in a preset time period, and determining a target data group for encryption from the uploaded data according to a preset rule, wherein the target data group is composed of different types of data from the uploaded data.

[0051] Among them, for data of the same security level that needs to be stored in the same sub-resource library, the same encryption algorithm can be used. Specifically, a target data group is obtained from the uploaded data, wherein the target data group is composed of data of multiple different data types, such as text, pictures, and videos, etc. The information in the target data group is used as an encryption element for the uploaded data. In specific implementation, the preset time period can be set according to actual conditions and is not limited here. In addition, in some optional embodiments of the present invention, the encryption time can also be determined by setting the amount of uploaded data. For example, when the amount of uploaded data reaches a threshold, encryption of the uploaded data begins.

[0052] More specifically, the step of determining the target data group for encryption from the uploaded data according to a preset rule includes:

[0053] Determining the number of types of data types of the target data group according to the security level of the uploaded data;

[0054] Determine corresponding type data from the uploaded data according to the number of types, and select target data from the type data to form the target data group:

[0055] Among them, the data type in the target data group for encryption can be determined according to different security levels. For example, for data with a higher security level, more types of data can be obtained from the uploaded data as the target data group, and for data with a lower security level, fewer types of data can be obtained from the uploaded data as the target data group. That is, according to different security levels, the types of data types in different target data groups are determined. For example, for data with a lower security level, one or two types of data can be selected to form a data group, while for data with a higher security level, multiple types of data can be selected to form a data group. In addition, since the uploaded data contains more than one data type of corresponding data, the uploaded data can be first classified according to the data type, and then the target data can be selected from multiple data in each data type. For example, after determining the data type, a data with a large data volume is selected as the target data of the data type as the target data group. Specifically, assuming that after classification, there are multiple pictures of data, the picture with the largest data volume is selected as part of the target data group.

[0056] Step S12, extracting each target data in the target data group respectively, and extracting the characteristic attribute information of each target data respectively, and encrypting them according to the characteristic attribute information to obtain multiple sub-encryption chains.

[0057] Among them, the target data group is composed of different types of data, each of which has its own unique characteristic information. The target data composed of the target data group are extracted respectively, and the characteristic information of the target data is extracted respectively. The encryption algorithm is used for each characteristic information to obtain the sub-encryption chain, which ensures the uniqueness and security of the encryption chain.

[0058] Step S13, determining a characteristic encryption chain according to the multiple sub-encryption chains according to a preset rule, adding the characteristic encryption chain to the head of the original encryption chain, and breaking part of the tail of the original encryption chain according to the length of the characteristic encryption chain to obtain a data encryption chain.

[0059] Among them, after determining multiple sub-encryption chains, a preset algorithm is used to merge the multiple sub-encryption chains to obtain a characteristic encryption chain. The characteristic encryption chain is added to the head of the original encryption chain to obtain a new encryption chain, and the part of the tail of the original encryption chain is cut according to the length of the characteristic encryption chain to obtain a data encryption chain. For example, the length of the original encryption chain is "16", and the length of the obtained characteristic encryption chain is "6". The two constitute a new encryption chain of "22". The "6" bits at the tail of the original encryption chain are cut off to obtain a data encryption chain of "16". Under the premise of realizing continuous updating of the encryption chain, the original length of the encryption chain is guaranteed.

[0060] In addition, in some optional embodiments of the present invention, the original encryption chain in the resource library can be actively set, or the encryption chain can be obtained by using an encryption algorithm based on information of data currently stored in the resource library as an encryption element.

[0061] Step S14: encrypt the uploaded data according to the data encryption chain and store it in the target sub-resource library.

[0062] Among them, the uploaded data is encrypted according to the obtained data encryption chain. In the specific implementation, a data encryption chain is configured for the uploaded data, and so on. As the data increases, the data encryption chain is used as the original encryption chain. The encryption chain of the next encrypted and stored uploaded data is updated again and used as the encryption chain of the updated part of the uploaded data, thereby realizing the secure storage of data.

[0063] In summary, the data management method of the online resource library in the above embodiment of the present invention obtains the security level of the uploaded data to be uploaded to the online resource library, determines the target sub-resource library to which the uploaded data belongs from multiple sub-resource libraries according to the security level; obtains the uploaded data of the same security level in a preset time period, determines the target data group for encryption from the uploaded data according to the preset rules, and the target data group is composed of different types of data in the uploaded data; extracts each target data in the target data group, and extracts the characteristic attribute information of each target data, and encrypts them according to the characteristic attribute information to obtain multiple sub-encryption chains; determines the characteristic encryption chain according to the multiple sub-encryption chains according to the preset rules, adds the characteristic encryption chain to the header of the original encryption chain, and breaks the tail of the original encryption chain according to the length of the characteristic encryption chain to obtain the data encryption chain; encrypts the uploaded data according to the data encryption chain and stores it in the target sub-resource library, divides the resource library into security levels, reduces the difficulty of unified high-complex encryption, and uses the unique characteristic information of the data itself to encrypt the data, thereby improving the security of the data in the resource library. The problem of low data security in the online resource library in the prior art is solved.
