A new inspection system, consisting of two procedures for the authentication of coins, is proposed in this paper. In the first
procedure, optimum image-matching positions are found by minimizing the matching error of the test coins with their prototype
coins. The second procedure is the decision-making process that inspects the coins as genuine or spurious by the Back-Propagation
Neural Network combined with the concept of eigen-section. Unlike the traditional approach based on gray-level values, the
quantity (8 bits) of the color’s scale has been adopted. The discrimination results are presented and discussed in this study. 相似文献

利用PBOC2.0金融IC卡的物理安全特性,提出了一个改良的匿名可分电子货币协议,以支持离线支付应用。该协议同其他基于半盲签名或基于知识证明的树状节点的可分电子货币协议相比,具有更高的效率。协议中还给出了完整的货币购买、使用、挂失、退还管理机制,以消除多个货币间的关联,最大限度地保证合法用户的隐私。最后,从密码学安全角度和金融安全规范两个角度分析了协议的安全性,保证协议在金融IC卡上移植的可行性和兼容性。此协议适用于网络交易、离线交易和P2P交易,其设计目的是作为PBOC IC卡应用的有益补充。 相似文献

Two experiments are reported in each of which subjects were shown photographs of assorted coins and were asked to count the number of coins of a specified denomination. Experiment 1, using only decimal coins, showed that people made few errors when counting new, 7-sided coins (50p), but many errors when counting circular coins (50p) having the same diameter as the new coin. Experiment 2 showed: (a)errors when counting (10p) coins were fewer in an assortment of £sd coins than when among decimal coins-with in the £sd coinage no other coin had the same diameter as l0p; (b) the l0p error rate could be reduced by enlarging the diameter of the 50p coin. These results suggest that the new 7-sided coin was not itself difficult to discriminate when it was tho search objective, but that it was sometimes mistakenly classified as the circular l0p when people were searching for lOp coins. To explain this asymetric confusability between the circular and non-circular coins, it is suggested that people vary tho salient dimensions used when searching for different coins-using predominantly shape for a non-circular coin, and predominantly size for a circular coin. 相似文献

Theory predicts that dismissing the 1 and 2 euro cent coins from the denominational range of the euro facilitates payment efficiency. To examine whether this theory holds true in practice, data were collected for the Netherlands before and after September 2004, which marks the day that retail stores were allowed to round all amounts at 5 euro cents. The data consist of wallet contents for three cross sections of individuals. As the amounts of various coins in wallets are correlated, a multivariate Poisson-log Normal model is proposed to analyze these data. It is found that rounding leads to less 1 and 2 cent coins in wallets, but that still other coins are over or underrepresented, thereby suggesting that the euro range does not yet lead to fully efficient payment behavior. 相似文献
