Space layout planning is the first phase in the process of designing a building. Though a large number of possible layout plans may be generated, a set of requirements and related constraints limits the number of possible options. In this paper, an automated floor plan is presented using genetic algorithm, AutoCAD as an implementing tool and Autolisp as a programming language. The topological and...
Steganography is used to hide the secret information within a cover media in such a way that the existence of the message could not be noticeable. Here we are considering audio file as cover media and text message as secret information. The secret information is embedded in a cover media as noise as the HAS cannot detect the sound less than 20Hz or greater than 20000Hz. Generally LSB algorithm is...
Constraints, specifically Separation of Duty (SoD) constraints, constitute an essential component for specifying Role Based Access Control (RBAC) policies. While it has been shown earlier that SoD constraints can be effectively represented using a set of t - t Statically Mutually Exclusive Roles (SMER) constraints, this paper presents a method for finding minimum number of users under multiple SMER...
In this work a PSO based algorithm has been proposed to improve the sturdiness against RS steganalysis. RS Steganalysis is commonly used method which detects the steg-message from the stego-image. A new method based on particle swarm optimization is proposed in this paper to improve the robustness of the stego image against RS steganalysis. The pixel values of the LSB steg-image are modified by the...
