Abstract: A Resource Reservation System includes a Token Generation Unit (TGU) which generates and circulates among nodes of a communications system a Slotted Token (SLT) message having sub-fields to carry identification number for each input port in a node and the resource available for each input port. On receiving the message the Resource Control Unit (RCU) in each node can write port identification number, available resource in appropriate sub-fields of the SLT message, and reserve resources in other nodes by adjusting information in the sub-field associated with the other nodes.

Abstract: Key-dependent sampling of a biometric characteristic is performed at a client, to thereby generate key-dependent biometric data samples. The key-dependent biometric data samples are then transmitted from the client to a server. By sampling the biometric characteristic at the client in a key-dependent manner, the key-dependent biometric data samples may be transmitted from the client to the server without the need for additional encryption and/or a signature. A key is preferably transmitted from the server to the client. The key is then used to perform the key-dependent sampling of the biometric characteristic at the client. The key-dependent sampling may be performed by sampling the biometric characteristic at a sampling frequency that is a function of the key. Alternatively, the key can be applied to the sampled biometric data, to thereby generate the key-dependent biometric data samples that are a function of the key. The key is preferably used to perform nonlinear key-dependent sampling of the biometric characteristic at the client, for example by using the key to determine the sampling frequency and also using the key to apply a nonlinear function to the sampled biometric data. Further encryption of the biometric data and/or the use of a signature with the biometric data need not be performed.

Abstract: Un método para transmitir de manera segura muestras de datos biométricos desde un cliente (110) a un servidor (112), caracterizado por las operaciones de: realizar (320, 336) muestreo, dependiente de la clave, de una característica biométrica en el cliente para generar de ese modo muestras de datos biométricos dependientes de la clave; y transmitir (340) las muestras de datos biométricos dependientes de la clave desde el cliente al servidor; en el que la operación de realizar comprende los pasos de: muestrear la característica biométrica a una frecuencia de muestreo que es una función de una clave para obtener datos biométricos muestreados; y aplicar la clave a los datos biométricos muestreados para generar con ello las muestras de datos biométricos dependientes de la clave.
