Research on robust audio zero watermarking algorithm based on discrete cosine transform [PDF]
MATEC Web of Conferences, 2020 This paper mainly uses the discrete cosine transform algorithm characteristics, combined with the “zero watermarking” embedding features, to improve the robustness of the watermark algorithm, to balance the uncoordinated relationship between robustness ...

Impact of Packaging and Recycling Systems on Material Recirculation: A Stage‐Decomposition Model
Packaging Technology and Science, EarlyView.A system‐level view emerges from decomposing recycling into four stages (participation, collection, sorting and process yield), diagnosing constraints and targeting interventions. Cumulative equivalent uses (CEUs) quantify long‐term retention, revealing marginal improvements at high baselines generate disproportionately larger gains than low‐baseline ...

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 ...

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

The Scientific World Journal, 2013 We put forward a fragile zero watermarking scheme to detect and characterize malicious modifications made to a database relation. Most of the existing watermarking schemes for relational databases introduce intentional errors or permanent distortions as ...

DrLS: Distortion‐Resistant Lossless Steganography via Colour Depth Interpolation
CAAI Transactions on Intelligence Technology, EarlyView.ABSTRACT The lossless data steganography is to hide a certain amount of information into a container image. Previous lossless steganography methods fail to strike a balance between capacity, imperceptibility, accuracy, and robustness, commonly vulnerable to distortion on container images.

The law of AI knowledge distillation
American Business Law Journal, EarlyView.Abstract Knowledge distillation—the practice of training a compact student model on the outputs of a larger teacher model—has emerged as the fastest‐growing technique for replicating and disseminating frontier artificial intelligence (AI) capabilities.
