Method and apparatus for distributing electronic content

摘要

A method of distributing electronic content such as music or books via the internet involves transmitting licence data with the content. The licence data includes status information indicative of whether the licence is a full licence for content purchased from a content distributor, or temporary for content passed from a full licence owner to a new consumer who has not yet paid for the content. License status data is transmitted with or without content from one consumer to another. Connection to the internet allows the content management program to connect to the content distributor and transmit all stored licence status information. Detection of temporary licences by the content distributor triggers a request for payment of the content, and payment results in transmission of replacement licence data having a full licence status back to the consumer.
