RMP Protected Content Demo

Our Protected Content demo aims to demonstrate how Web content may be protected so that every user must pay each time the content is viewed or used. This solution is particularly good at protecting complex pages with heavy formatting and integrated graphics. Use it for pages with mixed text, graphics, photographs, sounds, Javascript or Flash games.

CarrotPay uses a unique process to indicate to a merchant that a payment has been made. The basic process (called Protected Link), transforms link data provided by the merchant (also know as a URL), using a cryptographic process called SHA-1 hashing. The transformed data is embedded in square brackets (i.e [..]), in the link to the item being sold. This very simple technique has great power as the correct transformation can only be performed by CarrotPay and only after full payment has been verified. The transformed data can be used to construct the actual filename of the content being purchased or as an authorisation code to be processed by application software on the merchant's web server or on the Client in the case of Protected content and some Flash applications.

How does Protected Content improve on Protected Links?

A link (URL), that has been successfully through the payment process will have been transformed to enable the buyer to obtain their product. However, this URL once returned could be used many times to fetch the same content without further payment. This means that if the user forwards the returned URL to someone else or just paste it onto some BBS, other people will be able to view or fetch the content without having to make a further payment. RMP Protected Content is a method of stopping people from viewing content without paying each time, even if the URL is passed on by someone who has already paid.

How it works?

In simple terms, parts of your HTML page will be stored encrypted, and only decrypted after the correct authorisation code has been received as part of the processed Protected Link.
