TL;DR: A color multiple watermarking method based on DCT (Discrete Cosine Transform) and repetition code is proposed and simulated to protect the copyright ownership and validate the authenticity of multiple owners.

TL;DR: This work design a novel remote user authentication scheme using wireless sensor networks for agriculture monitoring using random oracle model and shows that the proposed protocol is secure and resists various kinds of malicious attacks.

TL;DR: Experimental results show that robustness is achieved by recovering satisfactory watermark data from the reconstructed cover image after applying common geometric transformation attacks, common enhancement technique attacks (like lowpass filtering, histogram equalization, sharpening, gamma correction, noise addition etc.) and JPEG compression attacks.

TL;DR: An enhanced mechanism for developing a three-factor secure mutual authentication scheme to attain effectively the security of the remote health-care system for patient monitoring and the comparative studies of the scheme with state-of-the-art schemes are acceptable.

TL;DR: The proposed steganographic scheme has been tested on a set of colour images and satisfactory results have been achieved in terms of embedding capacity and upholding the acceptable visual quality of the stego-image.
