Online signature verification has been a research topic of great interest, in line with the increasingly high security requirements of a networked society. In this paper, an online signature verification system based on the nearest template matching is designed. A set of function features are employed for comparing the dissimilarity between the test signature and the template database. The difference...
Hyponymy is one of the most critical semantic relations, which contributes magnificently to semantic dictionary, information retrieval etc. In this paper, a method of extracting hyponymy is proposed based on multiple data sources fusion, which convert the extraction of hyponymy to the extraction of hypernyms for target words. First, mining candidate hypernyms for the target words based on search engine,...
In this paper, it is shown a new comprehensive weighting to compute the weights of risk factors in information security risk assessment. firstly, the principal eigenvector is the representation of subjective weights by all risk factors pairwise comparison judgment matrix derived from AHP. Moreover, the objective weights of risk factors are calculated by the entropy weight method. Finally, the comprehensive...
In this paper, a test platform for baseband signal processing module of ADS-B is introduced, which is simple and efficient. The baseband signal processing module of ADS-B used in receiving system of ADS-B analyzes 1090ES ADS-B message of baseband. In order to reduce the risk of technology and business, it is necessary to ensure that the signal processing module of ADS-B works normally before delivery...
