Unsupervised, fast and efficient colour-image copy protection

摘要: The ubiquity of broadband digital communications and mass storage in modern society has stimulated the widespread acceptance media. However, easy access to royalty-free media also resulted a reduced perception intellectual value promoted unauthorised duplication practices. To detect discourage media, researchers have investigated watermarking methods embed ownership data into some authorities expressed doubt over efficacy protect paper introduces novel method images by introducing reversible, deliberate distortions original image. resultant image preserves size essential content with edge colour appearance. proposal provides an efficient reconstruction process using compact key reconstruct from distorted Experimental results indicate that proposed can achieve effective robustness towards attacks, while its computational cost quality are completely practical.
