TL;DR: Experimental results clearly indicated that the proposed technique is highly robust and sufficient secure for various forms of attacks without any significant distortions between watermarked and cover image.

TL;DR: Experimental evaluation shows that using combination of NSCT, RDWT, SVD and chaotic encryption makes the approach robust, imperceptible, secure and suitable for medical applications.

TL;DR: In this article, the authors demonstrate and disseminate the integrated nutrient management (INM) technology in the irrigated ecosystem of Balh Valley in India to develop sustainable crop production systems under cash crops and vegetables following an appropriate technology transfer model.

TL;DR: This paper discusses a lightweight encryption–based secure digital watermarking technique for medical applications that uses redundant discrete wavelet transform and singular value decomposition along with nonsubsampled contourlet transform (NSCT) to improve robustness and imperceptibility.

TL;DR: In this article, a joint encryption then compression based watermarking technique for digital document security is proposed, which offers a tool for confidentiality, copyright protection, and strong compression performance of the system.
