Finger print based license authentication scheme for Indian scenario: A Review

Archives of applied science research (2015)

D. Thilagavathy R. Prasanna Priyadarshinee Patnaik Pia Rämä

Fingerprint authentication or recognition refers to the automated method of verifying a match between two human fingerprints. Fingerprints are one of many forms of biometrics used to identify individuals and verify their identity. The analysis of fingerprints for matching purposes generally requires the comparison of several features of the print pattern. In this project, we use the Finger print authentication scheme which is a non-imitable biometric authentication scheme. By using this biometric authentication, we can prevent the non-licensed person from driving. Our proposed system consists of a smart card capable of storing the finger print of a particular person. While issuing the license, the specific person’s finger print is to be stored in the card. At the time that person’s details are fully stored in that database. So at anywhere the person should place on his finger on the finger print reader. That person’s entire information will be displaying.

Resilient group key agreement protocol with authentication security

M. Rajaram D. Thilagavathy N. Kanjana Devi

Many applications in Dynamic Peer Group are becoming increasing popular nowadays. There is a need for security services to provide group-oriented communication privacy and data integrity. To provide this form of group communication privacy, it is important that members of the group can establish a common secret key for encrypting group communication data. A secure distributed group key agreement and authentication protocol is required to handle this issue. Instead of performing individual re-keying operations, an interval-based approach of re-keying is adopted in the proposed scheme. The proposed interval based algorithms considered in this paper are Batch algorithm and the Queue-batch algorithm. The interval-based approach provides re-keying efficiency for dynamic peer groups while preserving both distributed and contributory properties. Performance of these interval-based algorithms under different settings, such as different join and leave probabilities, is analyzed The Queue-batch algorithm performs the best among the interval-based algorithms.

Scalable Contributory Key Agreement with Efficient Authentication

CiiT international journal of networking and communication engineering (2009)

M. Rajaram D. Thilagavathy

Many emerging network applications are based upon a group communication model. In a peer-to-peer or ad-hoc network which do not have a previously agreed upon common secret key,communication is susceptible to eavesdropping, Hence a secure distributed group key agreement is required to establish and authenticate a common group key for secure and private communication. This paper presents an authenticated distributed collaborative key agreement for dynamic peer groups. The protocol is distributed in nature in which there is no centralized key server, collaborative in nature in which the group key is contributory,dynamic in nature in which existing members may leave the group while new members may join. Instead of performing individual rekeying an interval-based approach is used. The Queue-batch algorithm used for rekeying substantially reduces the computation and communication cost. Key authentication provided focuses on security improvement.

Ban Technology Based Wearable Wireless Sensors for Real-Time Environments

Applied Mechanics and Materials (2014)

Kiran Venneti M. Lenin D. Thilagavathy

In recent years, there is a pressing need for energy conservation measures against power shortages. It is important to create a relaxed and healthy environment in order to improve the quality of life as well as the effectiveness of work. We get into the revolution concept of BAN (Body Area Network), In order to provide suitable personalized services, human information data needs to be monitored and analyzed. We have developed a wearable sensing system which measures biological data and activity data in daily life using body area network technologies. Like, air conditioning to control thermal environment uses a lot of (non-renewable) electric power. In focus to achieve a good balance between energy consumption and comfortable feeling for human, and a smart system to control thermal environment intelligently has been required. This paper proposes the smart system that estimates individual thermal comfort using skin wearable wireless sensors along with we will do longer-term measurements for data accumulation through data logger with the support of IEEE802.15.6.Here we utilize some key sensors are used like skin temperature sensor and ECG sensors and indoor monitoring through Thermo hygrometer to measure the humidity. Skin temperature will be improved to worn in suits and maximize to hide the load, and every sensor informations are connected to data monitoring server for human conditional analysis.

Time Controlled Cloud Environment with Self destructing Data system (SeDas) for Data Confidentiality

Figshare (2014)

S. Savitha D. Thilagavathy

Popularization of cloud technology and day to day usage of mobile Internet has become very common in today's fast moving world where people are subjected to post their personal information like account numbers, passwords, notes, and different vital data. This information are cached, copied, and archived by Cloud Service Providers (CSPs), typically for users' authorization and management. There are high chances for the data to fall into wrong side usage where it could be accessed illegally without the users' knowledge. In such situations security for the data on cloud has to be increased. Self-destructing information principally aims at protecting the users' data confidentiality. All the data and their copies become destructed or unclear after a user-specified time, with no intervention from the user part. SeDas system meets this challenge by a new combination of cryptographic techniques and active storage framework based on T10 OSD standard. These security procedures and its functionalities make sure that SeDas meets all privacy-preserving policies and is easy for practical use. Compared to the system without SeDas the performance for uploading/downloading files has been achieved better. Keywords: active storage, cloud computing, cloud service providers, cryptographic techniques, data confidentiality, self-destruction data system.

HYBRID DEEP LEARNING WITH ALEXNET FEATURE EXTRACTION AND UNET CLASSIFICATION FOR EARLY DETECTION IN LEAF DISEASES

ICTACT Journal on Soft Computing (2024)

Uddyalok Chakraborty D. Thilagavathy Suresh Kumar Sharma Awadh Kishor Singh

This study addresses the imperative need for early detection of leaf diseases in tobacco, pepper, and tomato plants, as these diseases significantly impact crop yield and quality. Existing methods often fall short in accurately identifying diseases across diverse plant species. The research aims to bridge this gap by proposing a hybrid deep learning approach, combining the robust feature extraction capabilities of AlexNet with the precise segmentation and classification prowess of UNet. The proposed hybrid model leverages AlexNet proficiency in extracting hierarchical features from plant leaf images and subsequently utilizes UNet for accurate disease classification. This synergistic combination enables the model to overcome the challenges posed by the varied morphologies of tobacco, pepper, and tomato leaves. Experimental results demonstrate the effectiveness of the proposed methodology, showcasing superior performance in terms of accuracy, sensitivity, and specificity compared to existing techniques. The hybrid deep learning approach exhibits promising potential for early and accurate detection of leaf diseases, contributing to sustainable crop management practices.
