Abstract: A system for executing a sale of information between a buyer and an anonymous seller. The buyer transmits a request for information to a website hosted by a server. A seller who has information transmits a response to the website indicating that the seller has relevant information to sell. The buyer and the seller negotiate anonymously through the server using unique, anonymous identifiers to agree to the price and content of the information. Upon agreement, the buyer deposits the payment in an escrow account. The seller is instructed to disclose information to the buyer through the anonymous relay system. The buyer reviews the information and, if satisfactory, transmits acceptance of it to the server. The server then instructs the escrow account to release the funds to the seller. If the information is not satisfactory, a third-party arbitrator decides whether the funds are released to the seller.
