【 Abstract 】　Social security card is authoritative for the convenience of the people to enjoy social security and human resources service rights. With the rapid development of "Internet +" application, it is important to take the internet authentication of social security card as the core, promote the construction of security application system, achieve the nationwide security acceptance environment for social security card, improve and enrich network applications, and complete services from offline outlets to line network extension.

Due to rapid development of IOT, the number of sensors increases dramatically in communication system. Based on this, IETF formulates the 6LoWPAN standard for IOT communication. This standard runs the IPv6 protocol based on the conventional IEEE802.15.4, so that numerous number of terminals will be available, and the communication between sensors with different hardware will be feasible. This paper discusses on the scenario and architecture of 6LoWPAN in IOT system, as well as its segmentation, header compression, routing and security issues.

Chinese landscape painting mainly describes the natural landscape of mountains and water. It is an important branch of Chinese paintings. Currently deep learning models achieve significant success in many domains, such as image classification, object recognition, image style transformation and automated image generation. In this research, a Chinese landscape painting automated generation model based on generative adversarial networks (GAN) is proposed. The model is trained with Chinese landscape painting images from Internet. The depth of the network and loss function are properly designed. The generator and discriminator are trained in an adversarial manner and finally a well-trained generator is obtained. Compared with true Chinese landscape paintings, the proposed model can generate images with Chinese landscape painting style.

The frequent occurrence of forest fire in nature has brought considerable losses to various countries. The design of an intelligent early warning system for forest fire is particularly important. The system is based on ZigBee intelligent networking system. It consists of the front-end module of the fire alarm information collection system, the system data forwarding module and the remote terminal module. Through the front-end data acquisition module, the fire alarm information of the forest scene is transmitted to the terminal module in real time. The information is processed by the terminal to form an information judgment, that is, the alarm can be displayed in the data monitoring center in real time. The information can also be sent to the patrol personnel through the mobile phone terminal to carry out real-time monitoring of the scene.

In view of the relatively complicated personnel management of Small and Medium-sized Enterprises (SMEs), this pa- per designs a personnel management system for SMEs to solve this problem. Firstly, the requirements of the system are analyzed, and the feasibility of the system is described. Secondly, the functional structure and database structure of the system are designed. Fi- nally, the realization of the system is given. This paper has a certain positive significance for software developers and personnel man- agers of SMEs.

Flexbox is an updated layout mode for CSS3 designed for the more complex web requirements of modern net works.The purpose of the Flexbox layout is to allow the container to have the ability to change its width, height, order, and so on, to fill the available space in the best way. In this paper, the application of Flexbox in responsive Web layout is introduced in detail through a case study of Web layout of campus network.

In order to improve the signal-to-noise ratio, scanning range and scanning flexibility of ultrasonic phased array scanning, a 256-element multi-group scanning ultrasonic phased array system is developed. Its probe, host computer and PC program are briefly described.

Based on the new NGN soft switch platform equipment, taking the concept of learning field as the starting point, this paper gives the content construction and innovative application method of the Modern Switching Technology practical teaching plat- form in higher vocational education, and designs the innovative experimental project content based on the integration of theory and reality, which can promote the improvement of students’knowledge application ability and the cultivation of vocational skills in higher vocational schools

With the concept of "Internet +" economic development in China, colleges and universities have begun to use the big data technology, cloud computing technology and Internet of things technology to carry out campus information education and ser- vice platform in the digital and intelligent campus construction, to form an open, interconnected and shared data transmission and public service system. This paper mainly discusses on the characteristics of the "smart campus" under the "Internet +" development environment, and puts forward the strategy of building a smart campus information platform in response to the inherent requirements of campus information development.

Digital media technology has become one of the main technologies supporting visual communication design. In order to improve the efficiency of creation, a multi-dimensional technology combining 2D and 3D creation is proposed. Taking the picture book based on multi-dimensional technology as an example, the application of multi-dimensional technology in the graphic design is deeply explored from the aspects of technology and visual effects, aiming to provide reference for graphic designers.

According to the research limitation of trust evaluation of cloud service, this paper proposes a trust evaluation method of cloud service based on context provenance and semantic rules. The method can ensure the credibility and security of cloud ser- vice. A novel trust evaluation framework of cloud service is constructed by means of data provenance based on demand analysis, and the function modules are designed and discussed exhaustively. Then, the context provenance of cloud service is described and ana- lyzed by PROV model, and the“questions-feedback”semantic rules are designed. At last, the algorithms of computing trust degree are discussed in detail. The analysis results show that the trust evaluation method can effectively collect and describe the provenance of cloud service. The method can also improve the trust evaluation quality of cloud service by semantic rules.

The problem of air pollution not only affects the health of the human body, but also affects the economy development. Anhui Province is an important part of the Yangtze River Delta. It is in the joint area of several major economic plates in China, and its economic position is important. This paper studies on the air pollution inAnhui province based on GIS technology. The most com- mon air pollutants in Anhui Province such as NO 2 , PM 2.5 , PM 10 and O 3 are selected as the research factors, and the spatial and tempo- ral distribution of these four pollutants is represented by the Kriging interpolation. The effect of natural factors and human factors on the air quality is quantitatively analyzed by the correlation analysis method.
