Block-Parallel Systolic-Array Architecture for 2-D NTT-based Fragile Watermark Embedding
H. P. L. Arjuna Madanayake, R. J. Cintra, V. S. Dimitrov +1
Number-theoretic transforms (NTTs) have been applied in the fragile watermarking of digital images. A block-parallel systolic-array architecture is proposed for watermarking based…

Fragile Watermarking Using Finite Field Trigonometrical Transforms
R. J. Cintra, V. S. Dimitrov, H. M. de Oliveira +1
Fragile digital watermarking has been applied for authentication and alteration detection in images. Utilizing the cosine and Hartley transforms over finite fields, a new transform…
