Abstract: The invention relates to localizing the position of a person speaking by using pictures of a pattern (21) on an object (20) worn by the person. The object (20) carries a complex pattern (21) that is optimized for determining the orientation of the object (20), the distance from the object to a microphone device (14) and/or to a camera (11). Moreover, the pattern (21) may be arranged for identifying the person carrying the object (20). The determination of the position of the person carrying the object (20) may be used to enhance speech recognition (SR) and/or to provide hands-free voice control of devices (DC), e.g. in hospitals or in industrial settings.

Abstract: An efficient solution for secure implementation of indirect addressing (IA) is described. IA may be used, for example, in networks of which the routing algorithms are not capable of multicast but also contain very constrained devices that, although requiring multicast, are not capable of repeated unicast. This ID is useful in wireless networks containing low-power low-cost devices.

Abstract: A method for configuring a biometric template protected authentif ication system, in which the desired classification threshold (T) is first selected to optimize the trade-i off between FAR and FRR of the system, and then the ECC used in the authentif ication process is chosen such that the number (b) of errors which can be corrected thereby is equal to or greater than the selected classification threshold. During authentif ication, the number (b) of errors in a first codeword derived from biometric data associated with a physical object is determined and used in the decision process to accept or reject authentif ication.

Abstract: The invention provides a method for authenticating a physical object (OBJ) using a first helper data (W1) and a first control value (V1) associated with a reference object. The method comprises a step to generate a first property set (S1) using a noise compensating mapping (NCM) on information derived from the first helper data (W1) and a metric data (Y) associated with the physical object, and a step to establish a sufficient match between the physical object and the reference object using the first property set (S1) and the first control value (V1). The method further comprises a step to generate an update data (WUPD) for updating the first helper data (W1) using the first helper data (W1), the first property set (S1) and the metric data (Y). Also provided is a client terminal configured to carry out the method.

A PUF pattern of the PUF device is damaged when using the item for the first time.

Abstract: There is provided an authentication method for a system (10) comprising several devices (30). The method involves: a) providing each device (30) with an identity value (pi: i=1, . . . , n) and a polynomial (P) for generating a polynomial key; (b) including a verifier device (p1) and a prover device (P2)amongst said devices (30); (c) arranging for the prover device (p2) to notify its existence to the verifier device (P1); (d) arranging for the verifier device (pi) to challenge the prover device (p2) to encrypt a nonce using the prover (P2)device's polynomial (P) key and communicate the encrypted nonce as a response to the verifier device (p1); (e) arranging for the verifier device (p1) to receive the encrypted nonce as a further challenge from the prover device (pZ) and: (i ) encrypt the challenge using the polynomial keys generated from a set of stored device identities; or (ii) decrypt the challenge received using the set of polynomial keys; until said verifier device (p1) identifies an authentication match.

Abstract: The invention relates to a method of authentication of a physical object and an apparatus applying said method. The method uses a helper data (W1) and a control value (V1) associated with a reference object to generate a first property set (C1) using the helper data (W1) and a metric (Y) associated with the physical object. It further comprises a step to generate a second property set (S1) using a noise compensating mapping (NCM) on the first property set (C1), as well as a step to establish a sufficient match between the physical object and the reference object using the second property set (S1) and the first control value (V1). The method is characterized by a step that generates an error measure (ERR) by quantifying the noise removed by the noise compensating mapping (NCM) using the first property set (C1) and information derived from the noise compensating mapping (NCM). Error measure (ERR) is subsequently used for generating an authentication decision (D).

Abstract: A relative movement sensor for measuring movement of an object (15) and the sensor relative to each other, the sensor comprising a plurality of lasers (3,5) for generating respective measuring beams and illuminating the object (15) therewith, and a plurality of respective photodiodes (4,6) for measuring changes in operation of each laser cavity caused by reflected measuring beam radiation re-entering the respective laser cavity and the optical wave in the laser cavity. The plurality of lasers (3,5) are operated in a time-multiplexed manner such that only a subset (i.e. one or more) of the lasers is operated at any one time, the remaining lasers being idle. This reduces peak power dissipation and prevents erroneous interference caused by measuring beam radiation from one laser entering the cavity of another laser.
