Sustainable Development, EarlyView.ABSTRACT Effective ESG implementation remains a critical yet persistently underachieved organisational priority, particularly in emerging markets where reporting standards, leadership capabilities, and regulatory environments remain inconsistent. This paper aims to develop an interpretive framework that senior leaders in large organisations can apply ...

Attack characterisation of compressed images [PDF]
, 2003 We propose the use of robust watermarks to enable the characterisation of attacks even after lossy compression, such as JPEG and JPEG2000. A previously constructed Bayesian framework is used to allow characterisation of attacks from a predetermined ...

Integer DCT based reversible image watermarking by adaptive coefficient modification
, 2022 S.218-229We investigate in this paper several possible methods to improve the performance of the bit-shifting operation based reversible image watermarking algorithm in the integer DCT domain. In view of the large distortion caused by the modification of

Image zero-watermarking algorithm based on region of interest
Tongxin xuebao, 2009 Based on ROI, a new watermarking algorithm was proposed.First, ROI was selected.Then, the wavelet transform was executed and ROI mask was constructed.Finally, the zero-watermarking was designed for the wavelet coefficients in ROI mask.The experimental ...

Unforgeable Red: Design and Application of SO‐Annulated Perylene Diimides for Anti‐Counterfeiting
Small, EarlyView.Sulfoxide‐annulated derivatives were synthesized as photoactive chromophores and implemented in photopatterning processes to design anti‐counterfeiting signatures with a double level of authentication. Patterns ranging from centimeter to micrometer size were obtained with high definition, and thereafter these approaches were tested in potential market ...

One Yeast, Sixteen Synthetic Chromosomes, Infinite Possibilities
Yeast, EarlyView.ABSTRACT The evolution of the yeast, Saccharomyces cerevisiae, from a genetically tractable model organism to a chassis for genome‐scale engineering represents one of the most influential trajectories in eukaryotic biology. The Synthetic Yeast Genome Project (Sc2.0) embodies the current height of this trajectory, having now delivered functional ...

Watermarking protocols for authentication and ownership protection based on timestamps and holograms
, 2022 S.240-251Digital watermarking has become an accepted technology for enabling multimedia protection schemes. One problem here is the security of these schemes. Without a suitable framework, watermarks can be replaced and manipulated.
