A Novel Digital Audio Encryption and Forensics Watermarking Scheme

IEEE Access
There are a large amount of audio signals stored in third-party storage centers. To improve the privacy and security of audio signals, a digital audio encryption and forensics watermarking scheme is proposed. We defined the signal energy ratio feature of

Hybrid Blind Audio Watermarking for Proprietary Protection, Tamper Proofing, and Self-Recovery

IEEE Access, 2019
The paper presents a lifting wavelet transform (LWT)-based framework for multi-purpose blind audio watermarking. The proposed schemes can be used to carry out robust watermarking for intellectual property protection as well as fragile watermarking for ...

Multiband Optical Physical Unclonable Functions Based on Mixed‐Phase Multilevel Emissive Perovskites

Advanced Science, EarlyView.
In this paper, sustainable multiband optical PUFs were developed by constructing heterostructures between lead‐free phase‐mixed perovskites and cellulose fibers via a water‐assisted drop‐casting process. Cesium manganese bromide perovskites provide an environmentally benign composition while exhibiting excitation‐dependent multilevel photophysical ...

Oldest well‐preserved euprimate petrosal, from the early Eocene of India (Vastan Lignite Mine, Gujarat)

The Anatomical Record, EarlyView.
Abstract An exquisitely preserved, isolated partial petrosal with associated fragmentary stapes is described from the Vastan Lignite Mine (Gujarat, India), dated to the early Eocene (~54.5 Ma). Several anatomical traits (e.g., large petrosal plate; posterolateral entry of the internal carotid artery to the tympanic cavity; bony tubes surrounding the ...

SMARTMed: semi-fragile dual watermarking with deep tamper detection and adversarial DNN fingerprinting for secure medical image transmission

Scientific Reports
Cloud-based electronic health records (EHRs) are vulnerable to modification during transmission and use, compromising security and privacy. To reduce this risk, we implemented a semi-fragile watermarking method using Slant Transform and chaotic sequences.

HYBRID DEEP NEURAL VIDEO WATERMARKING FRAMEWORK WITH ATTENTION-DRIVEN ROBUST EMBEDDING AND INTELLIGENT TAMPER DETECTION [PDF]

ICTACT Journal on Image and Video Processing
The rapid growth of digital multimedia sharing platforms increases the demand for secure video copyright protection and unauthorized content tracking. Conventional video watermarking approaches often suffer from low robustness, limited embedding capacity,

Evolutionary morphology of the haplorhine hamate

The Anatomical Record, EarlyView.
Abstract Primates adopt a variety of hand postures during an impressive diversity of locomotor and manipulative behaviors. Morphological research has found that elements of the hand skeleton, such as the hamate, hold key information for inferring hand use and locomotor kinematics in extinct species.

Semi Fragile Watermarking with Tamper Localization and Recovery using AMBTC Method

International Journal of Engineering and Advanced Technology, 2020
The watermarking scheme in digital media communication has become an essential tool in helping content creators prove ownership if any dispute arises in copyright infringement. In this paper, Discrete Wavelet Transform (DWT) and Singular Value Decomposition (SVD) is performed in the watermarking process which improves the authentication of the image ...

Human evolution and the obstetrical dilemma: The pelvic floor hypothesis

The Anatomical Record, EarlyView.
Abstract Human childbirth is mechanically difficult because a large‐headed, broad‐shouldered fetus must pass through a comparatively narrow, twisted bony birth canal. Traditional explanations of this “obstetrical dilemma” emphasize the role of bipedal locomotion in inhibiting the evolution of a wider, more spacious pelvis.

Variable grouping patterns in primates: A test of the better competitor hypothesis in male Verreaux's sifaka (Propithecus verreauxi)

The Anatomical Record, EarlyView.
Abstract Intraspecific variation in social organization (IVSO) within primate populations can arise due to male mating competition. Verreaux's sifaka (Propithecus verreauxi) populations exhibit both single‐male and multi‐male groups, providing an opportunity to examine the relationship between male competitive ability and social organization.
