Large-capacity information hiding scheme based on minimum pixel modification
Egyptian Informatics Journal, 2022 Information hiding is an important technique for security-related applications, and it can be used wildly in many scenarios. Secret data embedding methods are proposed in spatial, frequency, and other domains by researchers in recent years.

An area law for entanglement from exponential decay of correlations [PDF]
, 2013 Area laws for entanglement in quantum many-body systems give useful information about their low-temperature behaviour and are tightly connected to the possibility of good numerical simulations. An intuition from quantum many-body physics suggests that an

Symmetric- Based Steganography Technique Using Spiral-Searching Method for HSV Color Images
مجلة بغداد للعلوم, 2019 Steganography is defined as hiding confidential information in some other chosen media without leaving any clear evidence of changing the media's features.

Quiz Games as a model for Information Hiding [PDF]
, 2015 We present a general computation model inspired in the notion of information hiding in software engineering. This model has the form of a game which we call quiz game.

Genre-Based Information Hiding [PDF]
, 2012 While data encryption is an effective means of keeping data private it does not conceal the presence of 'hidden' information, rather it serves as an indicator that such data is present. Concealing information and hiding the fact that information is hidden are both desirable traits of a confidential data exchange, especially if that exchange takes place

Compositional Methods for Information-Hiding [PDF]
Mathematical Structures in Computer Science, 2008 Systems concerned with information hiding often use randomization to obfuscate the link between the observables and the information to be protected. The degree of protection provided by a system can be expressed in terms of the probability of error associated with the inference of the secret information.

Unified Description for Network Information Hiding Methods
, 2016 Until now hiding methods in network steganography have been described in arbitrary ways, making them difficult to compare. For instance, some publications describe classical channel characteristics, such as robustness and bandwidth, while others describe

FEBS Open Bio, EarlyView.Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...
