STUDY ON TWO STAGE AUTHENTICATION FOR ONLINE TRANSACTION IN MOBILE DEVICES

2024-02-22T07:48:31+00:00

In recent years with remarkable development in technology, single factor authentication e.g., passwords are no longer considered secure. The widespread adoption of online financial transactions has raised concerns about the security of digital payment systems. Multi-factor authentication is a security mechanism that entails employing additional techniques in addition to the usual login and password to verify a user’s identity. The use of two stage authentication has emerged as a critical security technique to reduce the risks of unauthorized access and fraudulent activities. This paper looks at how two stage authentications might improve the safety of online financial transactions. The paper examines the efficacy of two stage authentication in avoiding unauthorized access and financial fraud through a thorough analysis of recent literature and case studies. It explores numerous two stage authentication techniques, highlighting their advantages and disadvantages. These techniques include SMS-based codes, biometric verification, and hardware tokens. To overcome the shortcomings of the existing technique, we proposed a system that includes fingerprint authentication along with PIN at the time of money transaction to avoid unauthorized access.

Data Security Perspective in Secure Data Communication

With the enrichment of use of the internet the confidentiality and security of our information becomes vulnerable now-a-days. Security in confidential information becomes one of the key challenges in context of data leakage and unauthorised access of data. Data security is one of the main concern in recent data industry to prevent alteration and illegal access of data. To ensure utmost security researches are going on rapidly on data security aspects. Various security methods and algorithms has been introduced to protect our data. Data can be secured in multiple forms like converting the actual data into non-readable data by applying cryptography concept, Data can be hidden under any cover medium by applying stenography approaches and visual cryptography. Data can be authenticated through watermarking applications. Thus sensitive information can be protected from unauthorised access. These concepts have been introduced to satisfy main data security principles for ultimate protection.

The article presents a comprehensive overview record on sunspot observations conducted over a span of over four months. The study aimed to characterise and monitor sunspot activity on the Sun’s surface. High-resolution images and data were acquired using Dr. Maddy’s 150mm EQ Refractor Telescope, enabling the precise measurement of sunspot positions, sizes and magnetic field properties. Complementary validations were analysed as well. The observations reveal a dynamic and evolving sunspot population with periodic variations and long-term trends. The findings contribute to our understanding of solar activity and its potential implications for space weather. This work underscores the importance of continued sunspot monitoring for space research and solar science. With this comprehensive analysis, we have presented an article which would be directly accessible and exploitable for future research.

TO STUDY THE DIFFERENCE OF TEMPERATURE (DELTA) BETWEEN THE PEAK TEMPERATURE ON LEFT SIDE AND RIGHT SIDE DURING NORMAL FIRING IN GLASS TANK MELTING FURNACE

2024-02-22T07:48:32+00:00

Glass Tank Melting furnaces utilize a cross-fired approach, with burners alternating between the left and right sides in 20-minute cycles. During normal firing, a significant temperature difference, known as delta, is observed between the peak temperatures achieved on the left and right sides. This temperature delta exceeds the permissible limit of ±2 °C, resulting in furnace process instability and energy losses. To address this issue, a two-month action plan was implemented. In the first month, various parameters were analyzed to identify the key factors affecting the temperature delta. In the second month, corrective actions were taken, following a standard Kaizen procedure. Parameters investigated included combustion air flow, air-gas ratio, batch moisture, regenerator top and bottom temperature differences, natural gas flow, combustion air flow, draft pressure, burner parameters, flue gas analysis, net calorific value variation, and more. Notably, the combustion air flow, total gas flow, and air-gas fuel ratio demonstrated a strong correlation with the temperature delta. Several issues were identified, such as excess air and equipment calibration discrepancies. Recommendations for resolving these issues included adjusting excess air ratios, calibrating burner parameters, sealing cracks and holes, and upgrading flow measurement devices. Additionally, the study suggested reevaluating the correlation between net calorific value and gas flow. This investigation seeks to enhance furnace efficiency, minimize energy losses, and ensure a consistent temperature profile during glass production.
