P.s.a. for Hiding Scanned Documents within Images
PSA stands for Pixel Scrambling Algorithm. This algorithm was published early this year [Potdar, Chang 2004]. This paper shows a practical application of PSA and how we can hide scanned document within an image. The scanned document could be either hand written or printed. The main idea behind this algorithm is that most scanned documents contain alot of redundant data, which doesn’t provide an...
متن کاملHiding Information in Images
In this paper we present a new method of embedding information within digital images, called Spread Spectrum Image Steganography (SSIS). Steganography, which means \covered writing" in Greek, is the science of communicating in a hidden manner. SSIS conceals a message of substantial length within digital imagery while maintaining the original image size and dynamic range. The hidden message can ...
متن کاملHiding Fingerprint Minutiae in Images
We introduce an application of steganography and watermarking to enable secure biometric data (e.g., fingerprints) exchange. We hide fingerprint minutiae data in a host image, which can be a synthetic fingerprint image, a face image or an arbitrary image. It is this carrier image that is transferred to the receiving party in this exchange, instead of the actual minutiae data. The hidden biometr...
متن کاملData Hiding in Medical Images
This paper presents an efficient technique to hide text information in 3D medical images such as MRI and PET. It embeds text information only in the non-anatomical pixels. It ensures that no anatomical part of the 3D medical image gets contaminated. It makes the retrieval of 100% data. The technique has been tested on several MRI and PET images.
متن کاملHiding Data in Halftone Images
Most recent papers about visual cryptography for halftone images are dedicated to get a higher contrast decoded image. However, the hidden visual pattern often blends into the background image and leads to a confused image. In this paper, we propose an improved method for halftone image hiding. By using the proposed method, the background image can be eliminated and the hidden visual pattern ca...
