In today’s increasingly complex and dynamic network structure, cloud computing brings great convenience to computer users and meets people’s requirements for rapid computer data processing. The article firstly analyzes the cloud computing architecture and the security threats existing in the cloud environment, and explains the importance of cloud computing access control mechanism to ensure data security, starting from the traditional access control. Then it introduces the multi-authority attribute access control scheme based on blockchain and elliptic curve improvement, on the basis of which it proposes a blockchain-based cloud data security sharing model and a blockchain transaction privacy protection scheme, which both meets the user data privacy protection needs and realizes privacy computing. Finally, the security of the two schemes is analyzed, and compared with other schemes with the same mechanism. The results show that the blockchain-based cloud data security sharing scheme has better performance and scalability, which shows a stable linear growth of 1x, and the time load introduced by this scheme while enhancing the security of the encrypted data sharing system is acceptable compared to the other schemes to satisfy the application scenarios with large-scale access requests.

In order to improve the accuracy of automatic detection of malicious code, this paper focuses on the “texture” features of malicious code and the characteristics of different types of malicious code, which are also different, and uses them for the automatic detection of unknown malicious code by using the four machine learning algorithms of KNN, RF, NB and SVM to perform single-feature detection and multi-feature (GLCM, LBP and ngram feature merging) detection respectively. Four machine learning algorithms, namely KNN, RF, NB, and SVM, are used to perform single-feature detection and multi-feature (GLCM, LBP, and n-gram feature merging) detection respectively, and analyze the accuracy of the spatial relationship feature-oriented malicious code detection scheme. A multi-version oriented data protection model is proposed for the data storage space, data version, quantity management and recovery requirements involved in service emergency response. The relative performance errors between its data protection scheme and the plaintext scheme and the simple add noise scheme are analyzed. In all four machine learning algorithms, the detection rate of fused features is higher than that of single features, and the maximum difference can reach more than 60%. When takes the value of 9 or 3, the data privacy protection algorithm, the plaintext algorithm, and the noise-only addition algorithm in this paper have similar accuracy rates. With proper noise selection, this paper’s scheme has good performance in real simulation.

In this study, the ecological environment landscape pattern index was selected to construct the ecological environment landscape data representation model under the self-organized feature mapping network (SOM) technique. The input data to the model were monitored under unsupervised conditions and made more sensitive to specific characterization information in the neuronal structure (Hebb), which resulted in different groups of regular data. The moving window method shows that the landscape index is unstable under the 1000-3000m window and the magnitude of change begins to decrease at the 4000m scale. The data tends to stabilize at 5000m scale, and the stability of the data decreases at 6000-7000m, and the anomalous data increases at this time. In terms of landscape level, the aggregation and connectivity of the overall landscape of the study area increased and landscape fragmentation, complexity and diversity decreased under the 4000m window. The land use change model based on SOM network can well reflect the law of land use change in the sample area, which greatly expands the spatial analysis research method of land use change.

STEM education emphasizes the in-depth integration between the knowledge of different disciplines, which is based on real problem solving, aims to establish an organic link between education and life, and takes the cultivation of composite talents with a sense of innovation and hands-on ability as the fundamental purpose. Aiming at the current problems of STEM education, the development path of STEM+ education based on digital visual virtual reality is proposed. Then, combining the DEMATEL method and Interpretive Structural Modeling (ISM), the dynamic factors affecting the development of STEM+ education are explored. Finally, the fuzzy set qualitative comparative analysis (fs/QCA) method was used to analyze the group path of STEM+ education high-quality development. The results of the analysis of motivational factors show that the governmental promotion among the extrinsic motivational factors has a high centrality and is a deep factor that drives the development of STEM+ education. Synergistic motivational factors play the largest role among the three dimensions and are the key to ensure the development of STEM+ education. Endogenous motivational factors are the direct motivational factors for the development of STEM+ education and need to be focused on control. The analysis of the grouping paths in region C, for example, shows that there are two high-level grouping paths and three non-high-level grouping paths, multiple grouping paths with different paths, and high-level grouping and non-high-level grouping are in an asymmetric state. There are some differences in the grouping paths in the east, center and west, and the three regions’ high-quality development of STEM+ education cannot be separated from the support of state factors and response factors. This paper provides a path reference for realizing high-level STEM+ education high-quality development.

Aiming at the problem of large prediction error caused by the complex background of macroeconomic prediction, this paper proposes a macroeconomic prediction model based on time series clustering. The model adopts sparse self-encoder to deeply mine the features of the input vectors, constructs a bidirectional threshold cyclic unit network, and predicts the preliminary trend of the macroeconomy, and proposes a time series deep clustering algorithm that integrates the multi-scale feature extraction and clustering objectives of time series data into the same network. A sample generation strategy based on data augmentation and a multiclassification assistance module are used to extract the invariant patterns contained in the time series data to obtain a better representation for targeting time series clustering. Comparing this paper’s model with different forecasting models, the RMSE metrics are 0.0038 and 0.003 for the two time horizons, which are better than the other two models. The prediction range of this paper’s model for future GDP is 5.8%-5.9%, which is smaller than the GDP prediction range of the ARIMA model, indicating that this paper’s model is suitable for the realistic application of macroeconomic forecasting.

Computer image-assisted design, as a product born in the era, provides more inspiration and creativity for art design. Based on the study of the basic theory of color design and the theory of color harmonization, an intelligent color matching model integrating visual aesthetics based on conditional generation adversarial network is proposed. Then a candidate graphic layout generation method based on visual saliency is proposed, which not only considers the visual saliency of each element in the image, but also considers how to generate candidate text regions under the constraints of aesthetic rules. In the visual analysis analysis experiment, under different color transformations, the F-value of the subject’s gaze time was 2.548, with significance P=0.051, which is not significant. The F-value of average gaze point is 6.398, significance P=0.002, significant difference is obvious. From this, it can be concluded that the artistic innovation design method proposed in this paper can make the subject’s point of interest change with a large difference, and the color that highlights the target object can significantly attract people’s attention, which is a feasible artistic innovation design scheme.
