Research On The Application Of Tracking System Design And Database Watermarking For College Graduates

It’s significant for Shaanxi Vocational College of Economic Management to guide their graduates to be employed and to develop its majors, to know well about the graduates’employment status, to get the whole picture of the organizations’ comprehensive remarks on the graduates, as well as to follow their proposals and advice on teaching and management of the college. Based on its practical situation, Shaanxi Vocational College of Economic Management develops graduate follow-up survey system and puts it into use successfully. The system takes into consideration our vocational college graduates’real status of employment, analyses the deficiency of labor management, and develops a set of follow-up survey system based on B/S model, which is perfectly suitable for our college. The jobs and achievements are as follows:First and foremost, the system, which adopts the advantage of campus network and describes the major problems appearing in graduates’employment, includes four management modules-----the vocational counsel center, the organizations, the graduates, and the administrators. The focus is on the digital watermarking technology, which is used to improve the security of data in the network environment.Secondly, this paper involves user requirements analysis and considers the characteristics of data------using PHP code technology in the foreground and MySQL in the background and PHPnow integrated development environment on the whole. The users’work flow of the vocational counsel center, the organizations, and the graduates is also taken into account. The major business logic is concerned with case analysis of UML (Unified Modeling Language) and thus the system designing, actualizing and testing have been fulfilled.Eventually, the latest zero-watermarking technology is used in the system and many characteristics of data are extracted from database to structure corresponding zero-watermarking, both of which are to guarantee the security of data in the graduate follow-up survey system. The test experiment is amenable to be attacked, which verifies the security of the system and illustrates the fact that zero-watermarking technology can be well applied to the graduate follow-up survey system,and that the security and robustness of data are pledged as well.
