Wireless Medical Sensor Network (WMSN) is used in healthcare applications which have the collection of sensors connected to body or emergency care unit to monitor the patients’ vital signs. The privacy details of the patients have to be secured. Lot of techniques have been proposed to secure the health data. But there are some loop holes still exist for the attackers to hack the data. This is the major problem and to solve this issue some techniques have to be invented. In the proposed system we are comparing the four existing cryptosystems for its computation time. We choose the best one among them to encrypt the data.

An intrusion detection system is a device or an application which monitor network, system activities for malicious activities, policy violations and also produces reports to a management station. This paper surveys proposed work on Intrusion Detection System and describe about comprehensive classification of various IDS approaches according to their employed detection technique. The main categories explored in this paper are anomaly detection, rule based intrusion detection and PCA based modular neural network. Thus the paper’s main aim is to include the most recent advancement in the area intrusion detection system as well as predict the future course of research.

Organic single crystal of Guanidine Acrylate (GuAcr) was grown by simple inexpensive slow evaporation technique. The grown crystal was subjected into various characterizations like single crystal XRD, UV-Vis, FTIR studies, electrical, mechanical properties and SHG technique. The XRD data shows that the crystal belongs to orthorhombic structure. The UV-Vis spectral studies observed that the cutoff wavelength of the grown crystal is 320nm. Optical band gap of the grown crystal was also calculated, and it was found to be 3.99 eV. Vibrational frequencies of GuAcr crystal were confirmed by FTIR spectra. Electrical properties of the GuAcr single crystals were studied using impedance spectroscopy. Decreasing impedance with increasing temperature is indicated that the negative temperature co-efficient of resistance behavior like an insulator. Dielectric response of the crystal with varying frequencies was also studied. Second harmonic generation of the title compound was studied using Kurtz Perry- powder SHG technique. It reveals that as grown crystal is suitable for Nonlinear Optical (NLO) device fabrications.Keywords
