The suggested methods of  spatial domain hiding perform data hiding into  higher nibbles or moderatory bits (i.e. bits ¿2''  to ¿5'') of an 8-bit host image pixel using data  matching or substitution with pixel gray value error  minimization respectively. Both these techniques  offer higher robustness as compared to commonly used  LSB technique. In addition a new algorithm for  achieving higher robustness as compared to generic  DCT algorithm has been proposed based on long-tail  modeling of mid-frequency DCT coefficients. The work  contained also includes study on robust medical data  hiding along with compaction using computationally  simple Haar wavelet transform for illustrating its  feasibility in secure telemedicine application along  with a new effective technique of steganalysis based  on generating relative frequency histograms.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783843377539\"\u003e\u003ch3\u003eInformation Hiding Techniques for Image Covers\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783843377539","offer_id":39470112768093,"sku":"9783843377539","price":59.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/cf595d49-894d-4aba-8256-f336f0431cc1.jpg?v=1758876449","url":"https:\/\/shop.autorenwelt.de\/en\/products\/information-hiding-techniques-for-image-covers-von-harsh-vikram-singh","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
