Last week i had posted article on how to check if anyone is using your images.And now i am here posting about how to make your image copyright with your invisible signature.
This application allows you to sign your images. The sign is added directly to the image data. It doesn't use EXIF or stream file properties. The sign is invisible. The sign stays detectable after jpeg compression, scaling and cropping or for example PrintScreen&Paste.It can sign bmp,png,jpg,tif images and detect signature from images and PDF files as well.
Image Spider : Image Spider is a web crawler, that searches through whole internet for signed images. If it finds a signed image the owner of the image will be notified.Image Spider has two basic modes, random crawling and custom crawling. Custom crawling means testing images on URL given by users.
Image Spider can handle simple web pages, multi frames, PHP, ASP/ASP.NET pages as well.
Supported languages: English, French, Czech, Slovak, German, Russian, Dutch, Italian, Polish, Spanish, Simplified/Traditional Chinese, Portugese, Bulgarian, Norwegian, Swedish, Bosanski, Hrvatski, Crnogorski, Srpski
How does it work :
1. Detecting a previous signature : This tool will search for the previous signature if available
2. Inputting new signature : The free version inputs a visible signature at the bottom-right corner as shown in the figure. Only this is that,the signature doesn't take characters like @,# etc...!!
