Protecting Art Software Protection "WATERMARK"

 


Some Software only provides partial protection.

 

Use Photoshop to embed a "watermark".

This is copied from the 'help' files in Photoshop 5.5: "You can add copyright information to Photoshop images and notify users that an image is copyright-protected via a digital watermark that uses Digimarc PictureMarc technology. The watermark -a digital code added as noise to the image- is generally imperceptible to the human eye. The watermark is durable in both digital and printed forms, surviving typical image edits and file format conversions-and is still detectable when the image is printed and then scanned back into a computer. Embedding a digital watermark in an image lets viewers obtain complete contact information about the creator of the image. This feature is particularly valuable to image creators who license their work to others. Copying an image with an embedded watermark also copies the watermark and any information associated with it. For more detailed information on embedding Digimarc watermarks, refer to the Digimarc Watermarking Guide, downloadable for free from the Digimarc Web site.

Weaknesses of Watermarking Schemes

 

Defeat the watermark/ digimark entirely within photoshop using digimark.

1. filter/noise/median until the watermark is defeated. Actually, anything will do. Sometimes I do an add noise as well. Basically just defeat the water mark at this stage.

2. Add a new watermark at the highest setting/lowest image quality

3 superimpose over the top of the original, adjusting the opacity until you get a near perfect picture with no watermark simple really, with nealy indistinguishable results. picture looks great, no watermark, takes about 5 minutes, and a little bit of judgement.

These suggestion really don't work.
Image protect function written in javascript. if you right-click on an image to attempt to save it, it pops up an alert window with the copyright information.
<SCRIPT language="JavaScript">alert("type your message here")</SCRIPT>

or
Disable The Right Click
The following script will disable the right click on your page (this script is provided here with written permission from the author). When someone right clicks to save an image off your page, a message will come up letting people know that your information is copyrighted. This script only works on the newer browsers, and it's not foolproof. If someone really wants something from your page they can find ways around it, but at least it's a warning to people who want to take your graphics. Just copy and paste the following code, and make sure it comes right after your <head> tag:

<script language=JavaScipt"><!--//No right click script v.25 // (c)1998 barts1000 // barts1000@aol.com // Don't delete this header! var message="Sorry, that function is disabled.\n\nContents & Graphics Copyright ©your name\nOur work is not Public Domain, and should NOT be taken from this site."; // Message for the alert box // Don't edit below! function click(e) { if (document.all) { if (event.button == 2) { alert(message); return false; } } if (document.layers) { if (e.which == 3) { alert(message); return false; } } } if (document.layers) { document.captureEvents(Event.MOUSEDOWN); } document.onmousedown=click; // -->

Testing Your Digital Watermark
Digital Watermarking is not fool-proof and can be quite easily over-ridden.

Protecting Images and Bandwidth
Image and bandwidth theft is running rampant on the web, but there's a simple method to prevent both. Learn how to protect yourself using CGI and JavaScript.

Protecting CD's
Lead-lined bags, available from photo retailers, will weaken the x-radiation on film and reduce potential harm. However, the effectiveness of any particular lead bag depends on the intensity and electric potential of the X-ray generator, the lead's thickness, and the film speed. If you use a lead bag, check with the manufacturer for the effectiveness of their products with airport X-ray devices. The inspection process may be triggered by a lead bag on the scanner screen. In a typical airport surveillance situation, the baggage may be pulled aside for additional inspection.

Photo Release Forms

 

Legal Issues: Permission
As with all photographs, permission to use images is crucial.  The following examples are provided as illustrations to the concept of permission.  District school board policies, acceptable use policies, or other forms in place should be the first line of direction for the educator collecting and using photographic images.  These examples of forms are provided as an orientation to the spectrum of permission forms that can serve as potential models for content.

YAHOO Standard Removal Procedure:
Image Search crawls the Web for image files, and our crawlers comply with the Robots Exclusion Standard. In order to have your images removed from our index we require that you create a robots.txt file using the Robots Exclusion Protocol to indicate which files you want excluded.

Once you have placed this file at the root level of your hosting server, Yahoo!'s image crawlers will no longer access those files or directories you have stipulated. Please note, however, that it can take several weeks before your block may take effect in our index depending upon when you first implement your robots.txt file.
