Abstract

Disclosed herein are methods and systems for transmitting streams of data. The present invention also relates to generating packet watermarks and packet watermark keys. The present invention also relates to a computerized system for packaging data for transmission to a user. The system may utilize computer code to generate a bandwidth rights certificate that may include: at least one cryptographic credential; routing information for the transmission; and, optionally, a digital signature of a certificate owner; a unique identification code of a certificate owner; a certificate validity period; and pricing information for use of bandwidth. The present invention also relates to an electronic method and system for purchasing good and services by establishing an account whereby a customer is credited with a predetermined amount of bandwidth usage, and then charges are assessed against the account in an amount of bandwidth usage which corresponds to the agreed upon purchase value for the selected item.

wherein the transmitting is for at least one of the following;

receiving a request to purchase a selected item;

determining a purchase value for the selected item;

causing a debit to the purchaser'"'"'s account in an amount of bandwidth usage which corresponds to the agreed upon purchase value for the selected item; and

sending an instruction to deliver the selected item.

9. The electronic method of claim 8, wherein the selected item comprises a copy of digital data, further comprising:

causing the copy of digital data to be created; and

embedding a record of the transaction into the copy of the digital data.
