 Abstract

Free space optical communication proves to be very effective and efficient technology for wireless communication. This paper basically deals with the designing of FSO system for various digital modulation techniques. Performance investigation of PSK,QPSK,DPSK modulations in FSO system is analysed by varying attenuation ranges for several weather conditions including haze,rain,and fog and obtained better Q factor and minimum BER which is desired for better communication. DPSK is proved to be an effective modulation technique for all kind of weather conditions

 Abstract

Literature review was conducted with the aim to review the knowledge among adolescent girls regarding Breast Self Examination (BSE). Breast Self Examination (BSE) is a primary screening technique to detect Breast abnormalities. By performing regular Breast Self Examination, women would become familiar with their breast condition so as to enable them to detect any changes from time to time. It should be regularly performed by an individual female from young age. This is because Breast Cancer can develop at the very age of twenty. Self assessment of breast cancer is most important in the early age .It is necessary to make it essential to understand the cancer literacy in women. Breast self examination is reassuring. Once you have learned how your breast feels normally, each month re-examination may confirm you have not found any changes to report. And if any unusual changes do occur monthly breast self examination will alert the person at the earliest stage so that the person can take immediate advice from the doctor.

 Abstract

Today, health data stored in the cloud is considered a highly confidential record, which must be hidden to prevent unauthorized access to protect patient information. Therefore, security issues related to moving medical data to the cloud have attracted the attention of researchers and scientists. A hybrid of data encryption models used to store diagnostic data in medical images. The proposed hybrid encryption scheme is based on the integration of Blowfish and encryption algorithms. our proposed framework applies a set of security constraints and access control that guarantee privacy and protection of medical information. We believe that the proposed framework paves the way for a new generation of lower cost, more efficient healthcare systems.

 Abstract

With increase in convenience and advancement in digitization, the number of digital users also increased. This usage has increased comfort ability in conjunction with threats. ATM is one such concept of digital transaction and is also prone to many attacks. In this paper we present a novel Automated Multimodal Security for user of ATM and to the ATM itself. This system comprises of many advanced sensors, which regularly monitors the various physical attacks that are carried by criminals such as threatening the users with weapons to perform transaction against their will, forcefully accessing the cash compartment in the ATM or lifting the ATM from the booth. We have used Xtensa LX6 Micro-controller with ESP32 module with in-built Wi-Fi, Tilt Sensor, Smoke sensor and Metal detector. Whenever there is a disturbance in the position of the ATM, difference in threshold of MQ2 sensor and detection of metal in the ATM booth, a message will be sent to the concerned through the Wi-Fi of ESP32 module. Further, we discuss the implementation of our hardware along with the major components used.

 Abstract

Optical wireless is the alternative approach to complete the deployment of optical cable networks in case of failure in implementation.In iptilam wave the attenuation due to atmospheric turbulance conditions cause a performance degradation in Fso system.Thus it will lead to the deterioration of the signal power in iptilam cable.To overcome these challenges multichannel Fso,erbium doped fiber in optical link was adopted with high optical power.A hybrid Fso/fo link is simulated and investigated under different weather conditions.frog dust obtained better Qfactor and minimum BER is desired for better communication.

 Abstract

The project's aim is to create a secure and user-friendly environment for students who don't have access to a campus to take tests online from a variety of places. The research uses a variety of machine learning models to relieve the administrative load of detecting student misconduct on a wide scale. The model verifies and authenticates the applicants taking the test, and it checks for any irregularities on a regular basis. This is achieved by identifying video and audio that the model analyses in order to verify the student's honesty. The system's continuous analysis of the inputs allows it to verify the candidate's honesty, guaranteeing academic integrity in e-learning. From the viewpoint of the test taker, the system is both economical and simple to use, as it simply involves the usage of inexpensive web cameras and a microphone. User verification, audio processing, gaze detection, number of person detection, item and phone detection are the five main components that continually evaluate the essential behaviour clues. We create higher-level features to classify if the test taker is cheating at any point throughout the exam by merging the continuous estimate components and using a temporal sliding window.
