Aasma Ghani Memon, Sumbul Khawaja, Asadullah Shah · 2008
XML is a universal, platform independent language that describes the way, information can be stored, transferred and exchanged electronically. Any user on internet can access these XML documents & manipulate the information contents. Security is the prime concern in XML documents. Different security measures can be employed to ensure the integrity & confidentiality of XML data. Information hiding can be applied in XML documents which constitutes towards the field of steganography. Steganography is the art and science of hiding information by embedding messages within other messages so that unauthorized users can not access the information. This paper provides a new horizon for safe communication through XML on Internet. XML steganography is a solution which makes it possible to send news and information without being altered and without the fear of the messages being intercepted and traced back to sender. Different steganographic techniques have been designed which ensures that the integrity and confidentiality of data is maintained in XML documents. XML files can be secured by applying these techniques separately or by combining them. Applying these techniques collectively provides more security for the files.
