Intellectual property protection, steganography, digital watermarking, image protection, copyright protection, information hiding
Intellectual property protection of digital media involves
its copy and copyright protection. There is a wide array of
digital content like images, documents, audio, video, and
software, which needs to be protected from illegal use.
Though digital watermarking and steganography are older
phenomena but recently their importance has increased
due to their profound usage in copyright protection of
digital media. This paper discusses a steganography
technique to protect bitmap images. This technique is an
enhancement to the BPCS (Bit Plane Complexity
Segmentation) based steganography. Information hiding
in bitmap images is more difficult than in that of
compressed images. Similarly attacking such images is
also difficult. A password is needed to protect the image.
The resultant image is also a bitmap image that is visually
the same as the original image. The cover work, which is
hidden in the image, can be any type of the file. The
benefit of this scheme is its large capacity of message
embedding. This technique is very useful for hiding
copyright or other usage information in the image.
