Copyright in Digital Age - Part 7 - Technical Means of Protection

<< Copyright in Digital Age - Part 6

In order to indicate your copyright the legislation recommends putting on your image an invisible copyright mark. It’s hardly a good idea concerning a digital photo. In any way it won’t be able to protect your image from downloading. The image will appear on millions of sites and there will be no possibility to punish the thief.

But you can place a visual digital copyright mark, which will be visible visually and everybody will see whom this image belongs to. Even if this image spreads, what is unlikely, it’ll save the information about the copyright. You can place it with the help of the widespread programme Visual Watermark, which is easy to be found in the Internet.

The principle of its work is rather simple: you start the programme, download the image in it and point out what text or image to place in this image. The image alters externally and it’s impossible to restore the initial one, having deleted the copyright accurately. Now you can lay out your images quietly as you can be sure of protection of your rights.

Visual watermarks don’t disappear while resaving the image, altering the file format, altering the brightness, the contrast and any other processing in computer programmes. They ate saved even while printing the image and the following scanning of it. The less “imperceptible” marks you use, the better their resistance is. However, as my experience shows, even a small watermark placed in the right place is enough.

The use of digital watermarks is actually the most infallible way of your image protection from unauthorized use. As our experiments show, digital watermarks are present on the image after its polygraphic replication, even if the raster, characteristic of coloured illustrated magazines, is used, to say nothing of artistic albums.

The only drawback is that in order to have a possibility to use this way of protection, you should pay to the firm Watermark Software. Only then your name without any outside messages with the request concerning registration will be reflected in digital watermarks. However, you can assess the programme before purchasing and it costs not so expensive. You can also look through the terms on the site www.visualwatermark.com .

In order to use the possibility of applying visual watermarks, you should register yourself on the site www.visualwatermark.com and get the unique key, which should be introduced to the programme. Henceforth your copy of the programme will become fully functional and you will be able to protect quietly all the necessary images. There, on the site, you will be able to download programme updating, which appear quite often.

And let them steal now! You can always prove your authorship, simply presenting the original. And it will become clear, which of two images is the source.

Sometimes at the conferences in the Internet you can read that visual watermarks actually are not resistant, as owners of technology assert, and they can be removed from the picture with the help of serious graphic editors as photoshop. To tell the truth, it’s so. Such methods exist. However, first of all, in order to remove the watermark, a thief should possess serious knowledge in photoshop, and he, as a rule, doesn’t possess them. And secondly, such a programme can remove the marks from the image, but it can’t do it, without remaining any signs of such cleaning out. The picture is sure to alter. After the work of such programme it won’t be possible to determine whose copyright was on the image, before the programme worked. But it will always be possible to determine that this image is derived from the other, which has watermarks. And more, on the whole, is not required.
