A method of performing electronic communications between members of a group wherein the communications are authenticated as being from a member of the group and have not been altered, comprising: generating a plurality of random numbers; distributing in a digital medium the plurality of random numbers to the members of the group; publishing a hash value of contents of the digital medium; distributing to the members of the group public-key-encrypted messages each containing a same token comprising a random number; and encrypting a message with a key generated from the token and the plurality of random numbers.

End-to-end user anonymity is provided in electronic commerce or other types of online transactions through the use of an intermediary. An intermediary machine, which may be implemented in the form of a set of servers or other type of computer system, receives communications from a consumer or other user, and generates and maintains an alias for that user. Connections between the user machine and any online vendor or other web site are implemented through the intermediary using the alias. When the user desires to make a purchase from a given online vendor, the intermediary may present the user with a number of options. For example, the user may be permitted to select a particular payment card number and real destination address as previously provided to the intermediary. The intermediary then communicates with the online vendor and supplies intermediary payment information, e.g., a payment card number associated with the intermediary rather than the user, along with appropriate authorizing information and an alias destination address, e.g., a third party physical shipping address for deliverable goods, an alias electronic address for downloadable material, etc. The online vendor charges the purchase to the intermediary, and redirects the delivery of the goods or services to the destination address provided by the intermediary. The intermediary charges the payment card number of the user, and arranges for the redirection of the delivery to the real user address. In this manner, the invention provides complete end-to-end anonymity for the user, even when the user desires to enter transactions involving purchase and receipt of deliverable goods and services.

An anonymous trading system identifies the best bids and offers from those counterparties with which each party is currently eligible to deal, while maintaining the anonymity of the potential counterparty and the confidentiality of any specific credit limitations imposed by the anonymous potential counterparty. To that end, each bid or offer for a particular type of financial instrument is prescreened by the system for compatibility with limited credit information (for example, a one bit flag indicating whether a predetermined limit has already been exceeded) and an anonymous “Dealable” price is calculated for each of the traders dealing with that particular financial instrument.

A method, computer program product and electronic device are provided for providing hyper-local geo-targeting based on validated, user-supplied geographic information, wherein the user's anonymity may be maintained. In particular, user-supplied geographic information may be collected in association with a truncated IP address. Once collected, the user-supplied information may be validated using geographic data previously derived from one or more complete IP addresses corresponding to the received truncated IP address. The derived geographic data may have been derived using a system that maps the routing infrastructure of the Internet in order to determine where endpoints on the Internet are located. The validated, user-supplied geographic information, which may be more specific than the derived geographic data, may then be used to provide more granular and accurate geo-targeting, all the while maintaining the privacy of the individual users.

Apparatus, method and system for notifying a communications-switching center that subsequent communications directed to a wireless number associated with the wireless unit are to be routed to a destination number associated with the wireless unit. In response to a triggering event by the wireless unit through the base unit, the base unit can cause the wireless unit to transmit an SMS message to the communications-switching center. The SMS message can include a notification that subsequent communications directed to the wireless number associated with the wireless unit are to be routed to the destination number associated with the wireless unit.
