It is often necessary to watermark these media items in the compressed-encrypted domain itself for tamper detection or ownership declaration or copyright management purposes. It is a challenge to watermark these compressed encrypted streams as the compression process would have packed the information of raw media into a low number of bits and encryption would have randomized the compressed bit stream. Attempting to watermark such a randomized bit stream can cause a dramatic degradation of the media quality. Thus, it is necessary to choose an encryption scheme that is both secure and will allow watermarking in a predictable manner in the compressed encrypted domain.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9786202921589\"\u003e\u003ch3\u003eIntroduction, Analysis and Design\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Softcover - 9786202921589","offer_id":39465212051549,"sku":"9786202921589","price":61.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/b1ddedf0-18f8-4a71-b95f-735b0444606e.jpg?v=1773124390","url":"https:\/\/shop.autorenwelt.de\/products\/digital-rights-management-for-compressed-and-encrypted-images-introduction-analysis-and-design-von-ritu-gupta-anurag-mishra-sarika-jain","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
