Patent number: 11041933Abstract: A wireless node for use in a network of wireless nodes, for performing a localization to determine a location of a mobile device based on respective beacon signals transmitted wirelessly between the mobile device and each of a plurality of the wireless nodes. The first wireless node is configured to: wirelessly transmit or receive the respective beacon signal for use in determining the location of the mobile device; and wirelessly transmit information vouching for one or more others of the wireless nodes as being trusted for use in the localization. This information is transmitted to a device performing the localization (e.g. the mobile device), for use in identifying one or more rogue versions of said wireless nodes.Type: GrantFiled: June 9, 2015Date of Patent: June 22, 2021Assignee: SIGNIFY HOLDING B.V.Inventors: Sandeep Shankaran Kumar, Ashish Vijay Pandharipande

Patent number: 10743392Abstract: Disclosed are systems and methods for cloud-based monitoring and control of physical environments. In various embodiments, a computing device (1350, 1450, 1550) seeking to verify credentials of a lighting system controller (1352, 1452, 1552) may obtain unverified credentials of the lighting system controller. The computing device may transmit, to a first remote device via a first network communication channel, a request to verify the unverified credentials. The computing device may receive verification from the first remote device or a second remote device via a second network communication channel. The second network communication channel may be different than the first network communication channel. The computing device may compare the unverified credentials to the verification data and verify, based on the comparing, that the unverified credentials are legitimate.Type: GrantFiled: April 12, 2017Date of Patent: August 11, 2020Assignee: SIGNIFY HOLDING B.V.Inventors: Sahil Sharma, Sandeep Shankaran Kumar, Mark Henricus Verberkt

Patent number: 10681494Abstract: In one aspect, a mobile device is located using a signal sent out from the mobile device to nodes of a location network, and the mobile device also sends a tracking preference associated with the signal. This specifies whether a location network is permitted to use the signal to determine the mobile's location, and/or whether a provider of a location related service associated with a location network is permitted to make use of the location. In embodiments the preference may be tagged with the ID of a particular provider. In another aspect, the localization is based on measurements taken by a mobile terminal of signals sent from the nodes, and the nodes also send out an identifier with the signal identifying a provider of a location related service associated with the network. The mobile device can then use this identifier to determine who to share its measurements or location with.Type: GrantFiled: October 31, 2018Date of Patent: June 9, 2020Assignee: SIGNIFY HOLDING B.V.Inventors: Ashish Vijay Pandharipande, Sandeep Shankaran Kumar

Patent number: 10623950Abstract: A system (200) for protecting location information has beacons (240), a provider server (220) for providing at least one location based service, a location server (230) and mobile devices (210). The mobile device has a location engine (211) for controlling the location information and a location based application (212) for using the location information. The provider server generates unique data and authorizes the location based application, and subsequently provides location based services in dependence on an encrypted location. The location server determines the location based on a property of the radiation and encrypts the location. The location engine obtains a verification of customer data of the location based application, which indicates that use rights allow transfer of the location information to the location based application, and upon obtaining the verification transfers the encrypted location to the location based application.Type: GrantFiled: June 14, 2016Date of Patent: April 14, 2020Assignee: SIGNIFY HOLDING B.V.Inventors: Sandeep Shankaran Kumar, Ashish Vijay Pandharipande

Publication number: 20180288618Abstract: A wireless network (252) has a mesh structure of wireless communication links between nodes (210, 220). The network enables an unsecured node (230) to join the network by exchanging joining messages with a configurator (200). The configurator (200) is arranged for determining network security states including an insecure state in which all nodes are in the unsecured mode and the network is open for joining nodes; a partially secure state in which at least one node (210, 220) is in the secured mode and the network is open for joining nodes; and a secure state in which the network is closed to nodes in the unsecured mode. The nodes detect the security state and adapt their operation to the detected security state of the network and the mode of the device. The adapted operation enables flexible security bootstrapping of the network.Type: ApplicationFiled: October 28, 2015Publication date: October 4, 2018Inventors: SANDEEP SHANKARAN KUMAR, PETRUS DESIDERIUS VICTOR VAN DER STOCK, PETRUS JOHANNES LENOIR, THEODORUS JACOBUS JOHANNES DENTENEER
