Visual Cryptography-Based Secure QR Payment System Design and Implementation

It is important to validate the Merchant and the Client to increase confidence in online transactions. At present, only the Client is checked against the merchant server. The research in this paper will show you how to create and launch a QR code-based payment system that is both secure and convenient for users. As a result of their capacity to facilitate instantaneous transactions and offer unparalleled ease of use, QR codes have seen explosive growth in the past few years. QR-based online payment systems are easy to use but susceptible to various assaults. So, for the level of security given by transaction processing to hold, the secrecy and integrity of each payment procedure must be guaranteed. In addition, the online payment system must verify each transaction from both the sender's and the recipient's perspectives. The study's QR-based method is kept safe through visual cryptography. The suggested approach takes advantage of visual cryptography via a web-based application

AIR POLLUTION TOLERANCE INDEX OF WHEAT AND RICE IN THE PROXIMITY OF GAS BASED POWER PLANT

The study aimed to identify the tolerance level of rice and wheat due to air pollutants around the gas-based power plant. Ten sites were selected around 10km radius of gas based power plant. Major air pollutants like NOx, SOx, ozone, and PM10 were monitored in ten sites during the growth of rice and wheat. The Air Quality Index (AQI) of villages falls mostly in the category of moderately polluted sites. Air Pollution Tolerance Index (APTI) is a tool applied for categorizing sensitive or tolerant plants towards air pollution and is calculated by using four biochemical parameters like total chlorophyll content, ascorbic acid, pH, and relative water content of rice and wheat. Results indicated that the pH of cell sap of both the crops was acidic to neutral pH (3.5-6.9) at polluted sites while neutral to slightly alkaline (7.0-7.9) at less polluted sites. Ascorbic acid content was high at polluted sites since ascorbic acid shows a defense mechanism against air pollution. Chlorophyll content (up to 0.61mg/g) and relative water content have shown a significant decrease at most polluted sites. As per APTI values (APTI<11), both the crops were sensitive to air pollution in the selected area. APTI might be beneficial in the selection of crop species in the polluted area which shows that a higher concentration of air pollutants can damage crops severely. APTI was found to be positively correlated with pH, total chlorophyll content, and relative water content and negatively correlated with ascorbic acid

Rare Axillary Sebaceous Cyst Carcinoma: A Case Report with review of literature

Introduction: Sebaceous Cyst carcinoma (SCC) is a rare aggressive skin cancer derived from the epithelium of sebaceous glands. Sebaceous cyst carcinoma accounts to 1% of cutaneous malignancy. Sebaceous cyst carcinomas are generally divided into those occurring in ocular (75%) or extraocular locations. SCC is very rare in axilla and confused with secondaries from breast carcinoma or lymphoma.Presentation of the case: Here we are presenting a case of 38 year old male, who presented with painless, progressive swelling on left axilla from one year. He was evaluated with ultrasound breast and axilla and a fine needle ultrasound from the swelling. The FNA of ulcerated lesion in the left axilla showed positive malignant epithelial cells. The tumour cells display oval hyperchromatic to vesicular nuclei with moderate nuclear pleomorphism, conspicuous nucleoli in places and scant cytoplasm. The tumour cells are strongly immunoreactive for CK7, EMA, and CD10, weakly and focally reactive for CK20, and non-reactive for vimentin.Conclusion: In conclusion, Sebaceous Cell Carcinoma is a rare and aggressive malignancy. The fumigating mass in the axilla may rarely be a sebaceous cyst carcinoma, may present with or without breast lump, prognosis is very poor therefore should be treated aggressively and adequately
