A great portion of data on the Web lies in the hidden databases of the Deep Web. These databases can only be accessed through the query interfaces. The data information in these databases can only be obtained by data sampling. Efficient and uniform data sampling approach is very important to other research work, such as data source selection and ranking, for the data samples can give insight into...
In this paper, Study on the streams encryption key generator based on Chaos Theory, and the number of parameters by introducing a range of piecewise linear chaotic map(PLCM), to achieve encryption algorithm design, analysis results show that this algorithm has good initial value sensitivity nature, distribution, as well as auto-correlation function features. This design can use the logic hardware...
The final destination of Chinese E-government is to establish the "one-stop" pattern, which is on the basis of the construction of integration among different units and application systems. And the key point of integration lies in the realization of data between heterogeneous information systems. This article discusses the use of bus technology to solve the data exchange efficiently and...
