Abstract: A system and method manages and enforces user privacy of user data in a network environment in various manners. The system and method can determine a context for interaction with a party, filter user data to be provided to the party based on the determined context, and transmit the filtered user data to the party. The system and method can further determine an anonymity level at which interaction with the party is to be conducted, and interact with the party at the determined anonymity level. Additionally, to enforce user privacy, a privacy enforcement system can be employed at the receiving party and a trusted supervising authority can be utilized to supervise the access of user data received by the receiving party as well as to provide third party certification.

Abstract: The user's Bluetooth device substitutes a pseudonym address for the Bluetooth Device Address (BD_ADDR). The pseudonym address is a randomized version of the BD_ADDR. The pseudonym address is used in all the functions of the Bluetooth device that normally use the BD_ADDR, including the frequency hopping sequence, the device access code, the initialization key in link encryption, the authentication code, and the various packet addresses. In this manner, the user's privacy is protected by preventing the user's identity, routes, and activities from being correlated with his/her device's address. In addition to the Bluetooth standard, the technique also applies to other wireless standards.

Abstract: A method, system, and apparatus for protecting personal privacy in a wireless local area network using a framework at both the terminal and the service in the wireless local area network. The terminal includes a memory that stores the profile data for a user. The terminal is coupled by radio frequency to an access point that is also coupled to a wired network such as the Internet. A service operator coupled to the wired network offers a service opportunity to the user by sending a message to the terminal that includes the service opportunity. If the profile data for the user indicates that the user is interested in either this type of service opportunity or this particular service, the user sends at least a portion of the profile data to the service operator. The service operator uses the profile data to personalize the service prior to sending it to the user.
