一、概述 RFID是射频识别技术的英文(Radio Frequency Identification)的缩写,射频识别技术是20世纪90年代开始兴起的一种自动识别技术,射频识别技术是一项利用射频信号通过空间耦合(交变磁场或电磁场)实现无接触信息传递并通过所传递的信息达到识别目的的技术.     

Kid Gopher他用RFID来确认只有授权的成年人才可以接走学生

从2010年底到2011年初,KidGopher系统最先在北斯普林斯的小学试验.基于测试的结果,现在有17个小学建立该系统.学校的放学时间紧张而忙碌.教职工必须亲自确认每个孩子放学后都是被一个授权的成年人接走.然而混乱的局面可能导致误会或者错误.例如,孩子父亲或者母亲来接他/她的孩子时,他的孩子已经被一个朋友的父母接走,或者其他的监护人,或者一个没有被授权接孩子的人.因此,在某种情况下,当被心烦意乱的父母问到的时候,员工可能不能确认到底是谁来接的这个学生.KidGopher系统就是来着手解决这些问题的.     

Biometrics and the threat to civil liberties

Biometrics refers to the automatic identification or verification of living persons using their enduring physical or behavioral characteristics. Biometric systems fall into two categories: authentication and identification, with authentication systems being far more common. We discuss about the Biometric system and its use in authentication and identification. We also discuss about the face recognition system and the threat caused on the civil liberties due to illegal modification of the databases in the biometric system.     

Biometrics: truths and untruths

Biometrics is a scientific method used in technology to authenticate access to given critical resources. This system is based on the recognition of specific extremely personal ‘distinguishing marks’, that is to say unique physiological and behavioral traits. At a time when there is talk of ‘certainty of access’, that is to say of univocal authentication of the users of a service, biometrics could provide a valid alternative.     

Regression From Uncertain Labels and Its Applications to Soft Biometrics

In this paper, we investigate two soft-biometric problems: 1) age estimation and 2) pose estimation, within the scenario where uncertainties exist for the available labels of the training samples. These two tasks are generally formulated as the automatic design of a regressor from training samples with uncertain nonnegative labels. First, the nonnegative label is predicted as the Frobenius norm of a matrix, which is bilinearly transformed from the nonlinear mappings of a set of candidate kernels. Two transformation matrices are then learned for deriving such a matrix by solving two semidefinite programming (SDP) problems, in which the uncertain label of each sample is expressed as two inequality constraints. The objective function of SDP controls the ranks of these two matrices and, consequently, automatically determines the structure of the regressor. The whole framework for the automatic design of a regressor from samples with uncertain nonnegative labels has the following characteristics: 1) the SDP formulation makes full use of the uncertain labels, instead of using conventional fixed labels; 2) regression with the Frobenius norm of matrix naturally guarantees the nonnegativity of the labels, and greater prediction capability is achieved by integrating the squares of the matrix elements, which to some extent act as weak regressors; and 3) the regressor structure is automatically determined by the pursuit of simplicity, which potentially promotes the algorithmic generalization capability. Extensive experiments on two human age databases: 1) FG-NET and 2) Yamaha, and the Pointing'04 head pose database, demonstrate encouraging estimation accuracy improvements over conventional regression algorithms without taking the uncertainties within the labels into account.
