Abstract

A compressed Qubits image steganography based on an optimized adaptive neural networks is proposed in this paper, to solve many problems related to adjustment, size and recognition. that are considered inefficient in image information concealing. We used M-PSO algorithm to determine an optimal target vales of the adaptive neural networks to obtain low noise and high accuracy when the results trained. However, our proposed scheme can separately conceal secret message and the content of cover file.

Abstract

High-level Petri net has been used by more and more researchers for its high-level formalism. In order to facilitate the interoperability between different researchers and tools, we propose a novel logical approach, which is based on description logic and epsiv-connection, to formalizing and analyzing high-level Petri net (HLPN). First, HLPN-ontology (high-level Petri net ontology) is partitioned into algebra-ontology and structure-ontology for reuse and easy analysis. Then, algebra-ontology and structure-ontology are combined with epsiv-connection to express HLPN-Ontology in a compact way. The result of money changing service experiment, which is represented with high-level Petri net, shows that it is more efficient to analyze high-level Petri net with the approach discussed in this paper. The effect of using description logic and epsiv-connection is better than that of using Petri net markup language (PNML), which is an XML-based interchange format but it is not machine-processable.
