A New Approach for Information Security using an Improved Steganography Technique
Juneja, Mamta,Sandhu, Parvinder Singh Korea Information Processing Society 2013 Journal of information processing systems Vol.9 No.3
This research paper proposes a secured, robust approach of information security using steganography. It presents two component based LSB (Least Significant Bit) steganography methods for embedding secret data in the least significant bits of blue components and partial green components of random pixel locations in the edges of images. An adaptive LSB based steganography is proposed for embedding data based on the data available in MSB's (Most Significant Bits) of red, green, and blue components of randomly selected pixels across smooth areas. A hybrid feature detection filter is also proposed that performs better to predict edge areas even in noisy conditions. AES (Advanced Encryption Standard) and random pixel embedding is incorporated to provide two-tier security. The experimental results of the proposed approach are better in terms of PSNR and capacity. The comparison analysis of output results with other existing techniques is giving the proposed approach an edge over others. It has been thoroughly tested for various steganalysis attacks like visual analysis, histogram analysis, chi-square, and RS analysis and could sustain all these attacks very well.

In northern India, chickpea experiences abrupt heat and drought stress during the late developmental stage and entails significant production loss. In the present study, the effect of heat stress and combined stress (heat and drought) was assessed in five varieties of chickpea along with the underlying mechanism of cross-tolerance by priming. Healthy seedlings (24 days old) were primed with mild drought stress and exposed to three different temperatures, i.e., 38 °C, 35 °C, and 32 °C for 12, 24, and 36 h respectively, and also in combination with drought. The damage and tolerance were evaluated based on biochemical and physiological indicators. Results indicate that significant response was observed at 35 °C as compared to 32 and 38 °C in terms of decrease in leaf water content, increased electrolyte leakage and lipid peroxidation, decreased chlorophyll content, increased accumulation of proline and total sugars, and increased antioxidative activity of superoxide dismutase, catalase, guaiacol peroxidase, ascorbate peroxidase, and glutathione reductase. The consequence of combined stress was more distinct than the individual heat stress and cannot be extrapolated from the synergistic effect of the two stresses. In addition, priming induced cross-tolerance at 35 °C by improving the membrane damage, photorespiration, photosynthetic pigment, osmolyte accumulation, and some antioxidative enzymes. On the basis of all the above parameters, PDG4 was identified as the best performing variety and tolerant to heat stress while GPF2 was the worst performing and sensitive to heat stress. It can be inferred that both severity and duration of stress are important and priming can be considered as an important tool to induce cross-tolerance in crop plants.
Studies of the dielectric and ferroelectric properties of PZT: NZF magnetoelectric composites

Piezoelectric-magnetostrictive (magnetoelectric) composites using piezoelectric lead zirconate titanate (PZT) ceramic and magnetostrictive Ni-Zn ferrite (NZF) with compositional formulae (1-x) PbZr0.65Ti0.35O3-x Ni0.8Zn0.2Fe2O4 with x = 0 to 0.15 in steps of 0.05, were prepared by a conventional solid state route. The presence of individual phases was confirmed using X-ray diffraction. Dielectric properties were studied as a function of temperature and frequency presuming that the interactions between the piezoelectric and magnetostrictive phases may result in various anomalies in the dielectric properties of these composites. To study the ferroelectric properties, P-E hysteresis loops were recorded.
