| Image encryption was first introduced to the Internet by ArtistScope in February 1998. Prior to that encryption was only available for use with local files and not for viewing on the Internet. The images that are displayed on the web have been encrypted by our programs. When an image is displayed on your page, it is decrypted by our special applet and displayed instead of the original image (no longer needed on the server). Only the encrypted images are stored on the server and they are safe from the webmaster himself. |

Security applets
Since
ArtistScope began putting images into applets as image protection, a lot of
imitations have evolved. Most of these are simple image applets, and although they may prevent saving the image using mouse saves, they really offer no protection of the image that sits on the server. The image on your server, once its path is located by viewing your page code, can be directly linked and downloaded or displayed on any other web page. This is where clever image pirates can not only use your image, but also use the bandwidth that you pay for. Our encryption systems not only put a stop to this, but they also protect your images from tenants sharing your server tenants even from the webmaster himself… your images can only be displayed from a web page on your nominated web site. |

How it works:
Your film image is areas of colour suspended in an emulsion or film. When that image is scanned, it is converted to a digital image and represented by code, bits, bytes and so on, and stored on the computer as a string of code. For an idea of what this looks, like you can open a digital image in Notepad. When our programs encrypt the image, that code is parsed through an equation known as an algorithm. Algorithms were initially developed during the World Wars to protect secret messages, and even to this day, are very difficult to encipher. Each message is protected by its own unique algorithm, which is the formula needed to convert the message cack to its original form. Our encryption system works the same way, and each algorithm (key) is based upon the web site name used for the Domain Lock. So everybody's key code is different, and images encrypted for one web site cannot be used on another web site. As your applet viewer (the applet on your web page) loads an image, it first checks the domain that it is on, and then it checks the image. It then uses its algorithm based on your domain to uncode the image. If they match, your image is displayed to your visitor. If not, they get an error message. |
