Title: Transmission of anonymous information through a communication network
Inventor: MALKANI KARAN
IPC: H04L29/06
Filed: 2004-06-28
Abstract: A system that enables anonymous data collection from Respondents, such as over the Internet using public key technologies, where the anonymity and authenticity of Respondents is provided by a trusted mediation service. The invention provides a simple and secure solution that allows authentication of research Respondents while maintaining their anonymity. The Collector cannot link Respondent~s real identification and their responses, and a Mediator provides a communication service but has no access to the content of information exchanged between the Respondents and the Collector. According to one aspect of the invention, a Collector requests a list of anonymous Ids from the Mediator. The Mediator then generates a list of anonymous tokens which can then be used by the Respondents when they communicate with the Collector through the Mediator.

Title: Location beacon database and server, method of building location beacon database, and location based service using same
Inventor: MORGAN EDWARD JAMES
IPC: H04W4/029
Filed: 2005-10-28
Abstract: In one embodiment, to locate a user-device having a Wi-Fi radio, the device is triggered to transmit a request to all Wi-Fi access points within range of the user device.  Messages are received from the Wi-Fi access points within range of the user device, each message identifying the Wi-Fi access point sending the message. The signal strength of the messages received by the Wi-Fi access points is calculated. A reference database is accessed to obtain the calculated locations for the identified Wi- Fi access points. Based on the number of Wi-Fi access points identified via received messages, a corresponding location-determination algorithm is chosen from a plurality of location-determination algorithms. The calculated locations for the identified Wi-Fi access points and the signal strengths of the received messages and the chosen location-determination algorithm are used to determine the location of the user-device.
