Aquaculture intelligent monitoring and management system(AIMAMS) is a web information system covering businesses, home users, and management of aquaculture information, which have many users. The information security and safety equipment of different users is an important issue that we have to consider. Role-based access control introduces the roles concept into user and access rights, and its basic feature are that divide roles depending on the security policy, assign operating license for each role, and assign roles to each user. The user can access the specified object based on their respective roles. In order to achieve different user needs for security, aquaculture access control model based on group/role is developed which is based on analysis of the role-based access control model. Aquaculture intelligent monitoring and management system consists of system administrators, business users, family farming users and technicians, each category contains a number of other users who have different permissions. For such a complex distribution of competences, the user groups are introduced here on the basis of idea of role-based access control model. Users are divided into four groups which correspond to four categories of users, each group is given the largest collection of operational authority, and the users of each group are assigned different roles, which have all or part of privileges of the current group. Technicians can access business and family farming user's information, but cannot view some sensitive data, such as price, therefore, technicians group is controlled by field-level permissions of data tables, the sensitive fields of business and family farming user data tables is shielded. This model can effectively reduce the overhead of rights management,and can improve system's scalability. Along with the needs of businessdevelopment, the system can easily add new user groups and assign permissions and roles for them. This aquaculture access model is univers

Recently, personalized services finding in Smart City or Digit City is a hotspot in research area. City and urban areas contain plenty of services but some of them are difficult to extract and retrieval to people. Furthermore, with the development of the Semantic Web, more and more datasets are represented as RDF format and become part of the Linked Data, which provides a fundamentally new venue for personalized urban services retrieval in smart city applications. In this paper, we propose a personalized urban services retrieval framework which is performed by using ontology and comparing RDF-based user profiles with dataset in relation to civic services on web of data. To extract hidden information, the domain specific ontology is involved for linking entities on the web of data. The cases we envisage will show that the proposed framework can effectively return services resources with respect to the user's interests.
With the spurt progress of modern information technology, information technology has become the core of the advanced productive forces in modern science and technology in the information age. And the development of in...
