Reversible Data Hiding Scheme for ECG Signal

Tabassum, Naghma; Izharuddin, Muhammed - In: International Journal of Rough Sets and Data Analysis … 5 (2018) 3, pp. 42-54

In telemedicine system, remote electrocardiography (ECG) monitoring systems are widely used to examine the cardiac health of a patient. So, huge amount of ECG data is collected in real time and send over the network along with the patient's identity to his/her doctor who is geographically far...

Watermarking of Digital Images With the Substitution of Low-Value Bits to Increase Capacity

Erfannia, Aliasghar; Hatamlou, Abdolreza; Mahalleh, Farzaneh - In: International Journal of Computer Vision and Image … 7 (2017) 4, pp. 41-50

In this article, a novel watermarking method is proposed which applies the substitution of LSB for low-value parts of the image to embed confidential data. The watermark bits are encoded before being placed. Also, the data on the diameters of the host image blocks are selected on the basis of an...

Improving Scanned Binary Image Watermarking Based On Additive Model and Sampling

Wang, Ping; Luo, Xiangyang; Yang, Chunfang; Liu, Fenlin - In: International Journal of Digital Crime and Forensics (IJDCF) 8 (2016) 2, pp. 36-47

The SBWBAMS (Scanned Binary Image Watermarking Based on Additive Model and Sampling) algorithm proposed by Hou et al. owns strong robustness to the process of printing and scanning process. However, because the embedding strength used in the algorithm is set artificially, watermark information...

Steganographically Encoded Data

VASILESCU, Adrian - In: Informatica Economica XI (2007) 4, pp. 37-40

Steganography is the art of hiding information in ways that prevent its detection. Though steganography is an ancient craft, the onset of computer technology has given it new life. Computer-based steganographic techniques introduce changes to digital covers to embed information foreign to the...
