In 2008, Yoon et al. [25] presented three kinds of security attacks (YLY attacks for short) of a user authentication and key agreement scheme using smart cards in different scenarios. The YLY attacks are: perfect forward secrecy, the guessing attack, and the Denning-Sacco attack. The main goal of this paper is to propose a robust remote user authentication scheme using smart card that could not only...
This paper analyzed some shortcomings of old web database security and offered a new web database security model. Login module, audit module and program control modules were emphasized in the web database security model. Application of the web database security model was analyzed in the pork traceability information system. A new referral mode was offered for future web database security.
Vehicle-logo location is a crucial step in vehicle-logo recognition system. In this paper, a novel approach of the vehicle-logo location based on edge detection and morphological filter is proposed.. Firstly, the approximate location of the vehicle-logo region is determined by the prior knowledge about the position of the vehicle-logo ; Secondly, the texture measure is defined to recognize the texture...
The reliability of service is related to the kind and the number of service resources in grid. The kind and the number of service resources often change, so the service reliability is variable. In this paper, we propose a reliability measurement model for service in grid, which is based on the dynamic characteristic of service resource. In this model, the dynamic state of service is divided into a...
Based on the actual needs of project, this paper introduces a solution of cluster centers and attached matrix into application of Fuzzy C-means clustering algorithm in macro-economic forecast. We present the specific implementation of this algorithm, as well as the major steps of data mining. And in the end, an example is given to prove the solution’s effectiveness in macro-economic forecast.
