In this research paper another methodology for covering up literary information in computerized hued pictures has been proposed. Digital colored pictures will simply be used as a canopy media in steganography as a result of numerous deficiencies rumored in sensory system of mortals. In the proposed system we have utilized two non-subordinate disordered arrangement, for distinguishing the fundamental pixel positions where the bits relating to the mystery message must be inserted in the computerized cover picture. For implanting the message bits in the clamorously chosen pixels a 3-3-2 Least Significant Bit (LSB) addition strategy has been utilized. The proposed technique also provides a sufficient level of security because of the fact that same series of chaotically generated pixel locations for embedding the message bits is very difficult to be reproduced, till and unless the initial conditions of the 2 chaotic maps used for pixel selection method are well known. Additionally, the arranged method gives higher leads as far as PSNR (Peak Signal to noise ratio) and MSE (Mean squared error) values when contrasted, with optional existing strategies, subsequently guaranteeing that meddlers won't have any doubt that there is a message covered up inside the sent cover picture.

The USAID report on climate change vulnerability and adaptation in Ghana confirmed the impact of recent explosion of illegal gold mining in forest reserves and in river body. Government of Ghana responded to such wake-up call in deploying military combatants against perpetrators operating at day and midnight hours when drones are ineffective to monitor. We aimed at wireless sensor network (WSN) deployment to compliment military efforts for real time remote sensing. A conceptual framework on WSN technology is proposed based on expert view gathered from Delphi technique data analysis. A close textual reading of illegal mining editorial and the primary evidence of climate change impact from water shortage due to river body pollution with cyanide chemical in Ghana are key input factors for this technology-based conceptual exploration. Positive analytical feedback from the 'Delphi' suggests that we can apply this conceptual framework to all environmental case studies in which technology-based security protocols are good compliments to abort human intention towards certain behavior. The comparative discussion on the use of Drones, Satellite and WSN showed that the latter is: economical to deploy, energy efficient for continuous operational availability and reliable data sensing at midnight mining compared to drones' image processing power at night to track manual mining excavations. This study gives a starting point for uptake investigation in WSN deployment for surveillance on illegal mining; hence the findings may have limitations such as subjectivity of expert view. This conceptual framework is a recommendation to urgent national issue and thus it is relevant having real-world implementation for testing the human behavioral assumptions.

Regarding this study, an extensive review of secure and fast handovers schemes were studied with the aim of solving security problems and authentication server computational overhead experienced in the existing schemes in wireless fidelity based networks. The complete verification scheme outlined in IEEE 802.11i network is unsuitable to be deployed so as to support the user’s seamless mobility. The contribution of this paper suggested a robust delivery of handoff keys for internetworking and intranetworking schemes with a dedicated trust relationship model existing in diverse domains. Inter-access point protocol was used to transfer handover credentials in an intra-domain network. Likewise, an inter-access control-tunnelling protocol with opportunity key caching and pairwise master key caching are suggested for inter-domain security context-transfers. Man-in-the-middle attacks are tasked to break mutual authentication for wireless networks. This paper pinpoints out that the suggested fast handover authentication scheme in our study outperforms the scheme of Wang and Prasad and other schemes mentioned in the extant studies. The proposed authentication scheme prevents replay attacks, masquerading and message modification.
