GSM-R is an important transport communication system to realize moving block control so as to maximize the transfer capacity. However, if the GSM-R system is compromised, the transport system has to downgrade to fixed block control which is of low capacity. This paper presents secure train-to-train communication schemes which enable moving block control even if the GSM-R system is under attack. Particularly,...
According to a popular pattern recognition method, this paper proposes two methods to generate a secret from individual's biometric information, such as fingerprint feature points. One method is to recover a secret based on Chinese Remainder approach. Another is to fake some chaff points based on the general biometric feature points, and then recover the secret based on polynomial fitting. In order...

We seldom confuse these images with the objects per se mainly with the help of the contextual information from the surrounding environment and nearby objects. Without this contextual information, distinguishing an object from an image of the object becomes subtle; it is...
