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.
We employ an Image Spider which crawls the Internet looking for signed images. If it finds your signed image, it will let you know.
We can sign 3x8 bits(24 bit) bmp,png,jpg,tif images and detect signature from images and PDF files as well.
Now the SignMyImage is implemented as a plugin for Photoshop, standalone application with GUI and as a command-line program.
Image Spider is a web crawler, that searches through the 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.
