Contemporary college students have a very rich campus life, with a variety of organizations. Most students have participated in at least one community organization. However, the current organizations and clubs of all universities and colleges have rather cumbersome work procedures, resulting in management inefficiency. In addition, they are acting without sharing information with each other. In order to solve these problems, an Org community organization and cooperation platform is developed. Through the combination of online and offline, different users are given corresponding permissions, providing functions such as news release, activity check-in, goods leasing, schedule arrangement, community exchange and so on. The platform is developed based on Android Studio and server is built using Linux, Apache, MySql and PHP.

Firstly, this paper discusses on the importance of intelligent dormitory management system in colleges and universities, then studies on the K-means algorithm, and applies the algorithm to the intelligent dormitory allocation. At last, the data of individual students are collected through questionnaire survey and preprocessed and normalized. K-means algorithm is used to cluster the data of individual students. The validity and relevance of the algorithm in the three-dimensional space of data set dimensions, emotional stability and ID are discussed.

With the rapid development of virtual reality technology, more and more researchers are devoting themselves to the research of dynamic gestures recognition. Gesture recognition is a natural and friendly way of human-computer interaction. In this paper, a dynamic gesture recognition system based on Hidden Markov Model (HMM) is built. This system collects dynamic gesture data through Leap Motion and can recognize 36 letters and numbers of gestures (digits 0-9 and A-Z). A lot of experiments show that the system has strong robustness and can recognize individual hands. The recognition rate of potential can reach 93.2%.

With the development and progress of the economy and society and the arrival of the network era, we have fully enjoyed the convenience brought by the information age, and the influence of information on people's lives have become increasingly prominent. However, the risk of improper use of personal information is increasing, such as the credit card theft, mobile phone fraud, and so on. The serious leakage of personal information not only involves personal reputation, but also disturbs the normal order of production and life. Therefore, this paper analyzes the existing countermeasures to prevent the leakage of personal information on the Internet, and on this basis, puts forward a more perfect solution, and uses domestic cryptography technology to realize the omni-directional protection of personal information security on Internet.

The key points of control and future work are highlight by focusing on the management and protection of personal data in insurance enterprises. Furthermore, the idea of security management and protection of personal data in insurance enterprises are clarified.

The traditional virus defense measures are only aimed at the individual virus defense, lacking omni-directional defense measures, resulting in an inability to effectively protect the virus. This paper discusses on a kind of omni-directional virus defense scheme, improving the virus defense ability.

Nowadays, Wi-Fi and cellular mobile network have become universal, so wireless network security is becoming more and more important. At present, the Man-in-the-the-Middle Attack on the wireless network has existed in a large amount, and it is also an attack means with a great threat. This paper discusses on the Man-in-the-the-Middle Attack of the wireless network from the aspects of the technical principle, the attack mode, and the defense methods.

With the continuous expansion of information technology in the insurance industry, more and more business data is available in vertical areas, which inevitably brings great challenges to the storage and query efficiency of traditional structured databases. How to realize data redundancy backup and fast and efficient query has become a major problem of enterprise information technology. This paper presents a distributed search engine based on ElasticSearch, which combines with Logstash to collect data. It can filter, store and index vehicle data, and provide a unified query entry and efficient retrieval service for insurance policy issuing system. Practice shows that the system can achieve redundant backup of data and improve the efficiency of retrieving vehicle data. At present, it has been applied in the core system of insurance industry and achieved good results.

Moving target detection is a research hotspot in computer vision, image processing and other related fields. The core is to study and process each frame of image in video image. The main research idea of this paper is to compress and sample the two-dimensional image of each frame into a one-dimensional signal with a small amount of information, and reconstruct the image. Finally, the moving target extraction is performed on the image of each frame by the target detection technique. Simulation experiments show that the method is feasible and effective, and can greatly reduce the amount of data recorded in the target detection, and solve the problem of storage and transmission of massive data.

The Sydney Agreement is one of the most influential mutual recognition systems in the field of international engineering education. It is applicable to the engineering and technical majors of higher vocational education in China. At present, although China has not yet joined the agreement, in order to strengthen the international recognition of professional education, in line with the trend of talent internationalization, the entry of higher vocational education into the Sydney Agreement has become an inevitable trend of professional development. This paper proposes a “5+2” model for the assessment of the achievement of graduates' core competencies in the certification of the Sydney Agreement, ensuring the objectivity and effectiveness of the assessment results, and continuously improving the core competence of the students. Cultivation provides an effective basis.
