A Comparative Study on Steganography Digital Images: A Case Study of Scalable Vector Graphics (SVG) and Portable Network Graphics (PNG) Images Formats
نویسنده
چکیده
Today image steganography plays a key role for exchanging a secret data through the internet. However, the optimal choice of images formats for processing steganography is still an open issue; therefore, this research comes into a table. This research conducts a comparative study between Scalable Vector Graphics (SVG) image format and Portable Network Graphics (PNG) image format. As results show, SVG image format is more efficient than PNG image format in terms of capacity and scalability before and after processing steganography. As well, SVG image format helps to increase simplicity and performance for processing steganography, since it is an XML text file. Our comparative study provides significant results between SVG and PNG images, which have not been seen in the previous related studies. Keywords—Image steganography; data hiding; raster and vector images; Scalable Vector Graphics (SVG) and Portable Network Graphics (PNG) images format

SVG Language (Scalable Vector Graphics) For 2D Graphics in XML and Applications
The SVG technology is an open source copyrighted material of the W3C consortium and it is a language for 2D graphics within the XML (eXtensible Markup Language). The combination between SVG and JavaScript offers a powerful platform usable for interactive 2D graphics, comparable to the Flash and Java technologies. SVG offers XML graphics for the Web using three types of graphical objects: vector...

Digital Rights Management (DRM) system is the effective scheme for digital transactions. The main disadvantage of DRM is that once the content is decrypted, it can be easily copied using widely available utilities. It can be removed by using protection system like steganography. Steganography is the art of communicating in a way which hides a secret message into the main information or cover. T...
