Source cell-phone recognition from recorded speech using non-speech segments
Cemal Hanilci,Tomi Kinnunen +1 more
TL;DR: Experimental results using Mel-frequency and linear frequency cepstral coefficients (MFCC and LFCC) show that features extracted from the non-speech segments of speech contain higher mutual information and yield higher recognition rates than those from speech portions or the whole utterance.

A novel blind reversible method for watermarking relational databases
TL;DR: This article introduces a novel blind reversible water marking method that ensures ownership protection in the field of RDB watermarking, whereas previous techniques have been mainly concerned with introducing permanent errors into the actual data, this approach ensures 100% recovery of the original database relation after the watermark has been detected and authenticated.

An Efficient Watermarking Technique for the Protection of Fingerprint Images
TL;DR: In this article, the authors embed the watermarks into the ridges area of the fingerprint images so that the technique is inherently robust, yields imperceptible watermarks, and resists well against cropping and/or segmentation attacks.
A survey on steganography techniques in real time audio signals and evaluation
TL;DR: The general principles of hiding secret information using audio technology, and an overview of current functions and techniques are surveyed to construct a useful and useful data hiding application.

Robust gray-scale logo watermarking in wavelet domain
TL;DR: The experimental results show better visual imperceptibility and resiliency of the proposed scheme against intentional or un-intentional variety of attacks and superiority is carried out by comparison made by us with the existing schemes.

Secure spread spectrum watermarking for multimedia
TL;DR: It is argued that insertion of a watermark under this regime makes the watermark robust to signal processing operations and common geometric transformations provided that the original image is available and that it can be successfully registered against the transformed watermarked image.
Journal ArticleDOI
Techniques for data hiding
TL;DR: This work explores both traditional and novel techniques for addressing the data-hiding process and evaluates these techniques in light of three applications: copyright protection, tamper-proofing, and augmentation data embedding.

A digital watermark
TL;DR: The paper discusses the feasibility of coding an "undetectable" digital water mark on a standard 512/spl times/512 intensity image with an 8 bit gray scale, capable of carrying such information as authentication or authorisation codes, or a legend essential for image interpretation.
Journal ArticleDOI
Image coding based on a fractal theory of iterated contractive image transformations
TL;DR: The author proposes an independent and novel approach to image coding, based on a fractal theory of iterated transformations, that relies on the assumption that image redundancy can be efficiently exploited through self-transformability on a block-wise basis and approximates an original image by a Fractal image.
