Cryptographic Communication Based on Digital Image Watermarking

تاریخ : جنوری ۲۰۱٦ - موجودہ

Today, exchange of information is been held electronically. Digital data can be stored efficiently with a very high quality and it can be manipulated very easily using computers. Digital media offer several distinct advantages over analog media. Therefore, we have great need of secure transmission of the concerned data. Watermarking is used as a key solution to make the data transferring secure from illegal interferences. A watermark is a secondary image, which is overlaid on the host image, and provides a means of protecting the image. Watermark techniques are used in various areas such as copyright protection, broadcast monitoring and owner identification.In our project we purposed a image watermarking technique by using bit plane slicing then we embedded a data into optimal plane.we are examined different noise attacks on the watermarked image and observer can these noise attack affect the image.we also study the problem of watermarking different cryptographic projects such as pseudorandom capacity (PRF) assessment, unscrambling, and marking.
