Regulating access to digital content

摘要

Digital content such as text, video, and music are stored as part of a compressed and encrypted data file, or object, at a client computer, such as a personal home computer. The content is inaccessible to a user until a payment or use authorization occurs. Payment or use authorization occurs via a real-time, transparent authorization process whereby the user enters account or use data at the client computer, the account or use data is transmitted to a payment server computer, the account or use data is preprocessed at the payment server computer and if payment information is required and is present, the payment information is transmitted to a payment authorization center. The payment authorization center approves or rejects the payment transaction, and bills the corresponding account. The authorization center then transmits an authorization signal to the payment server computer indicating whether the transaction was approved and if not, which information was deficient. In response, the payment server computer transmits a token to the client computer, and if the token indicates approval, an installation process is initiated at the client computer whereby the object is activated and locked to the particular client computer. The object can be reopened and reused at any time on that particular computer. If the object is transmitted or copied to a different computer, the required payment or use information must again be tendered for access to the content.
