| مستخلص: | In this paper, three novel schemes have been presented for organizing the secret bits inside between-words spaces of cover-text before embedding process starts. The primary scheme conceals one bit within each between-words space; the second conceals a group of bits in the assembly of between-words spaces to control the span of cover-text and third scheme designate a lesser number of bits to higher frequencies letters improving payload with a controlled measure of stego-cover-content. Innovative algorithm for implanting and extricating have been proposed for making an interpretation of secret content into a remarkably secured encoded frame thereby acquire secret bits at that point choose any of three bits arranging plans finally inserted into focused locations of PDF cover-file. The proposed extraction process provides authentication of received stego-cover file such that only desired file is acknowledged for the extraction process otherwise fake file is discarded by a recipient. Experimental result demonstrates that the proposed technique provides productive algorithms in the term of high payload, enhanced security of hidden information and work well against steganalysis attack. |
