Guardian-Based Anonymous Password Management with Privacy Preservation Using Threshold Cryptography Harivignesh K.S., Venkatesan R., Selvarathi M., Jasmine David D. Journal of Trends in Computer Science and Smart Technology, 2026 Most password managers are designed as a compromise between providing a secure way to handle difficult login credentials and creating a system that keeps user information private. Most password managers store users’ sensitive information in a central location, leaving users vulnerable to hacking attacks. The proposed work creates a better way to manage passwords and provide more protection to users based on their private information through a new concept called Guardian-Anonymous Password Management (GAPM). The idea is to create a unique architecture that stores passwords in decentralized locations using guardian anonymity, creating a hybrid architecture of secret sharing with post-quantum encrypted wraps. Accordingly, GAPM separates the act of recovering user passwords from a person, using a set of anonymous guardians who securely recover users’ passwords without putting any of them at risk of being hacked or located through social engineering techniques like phishing. This is achieved by using a Shamir-style secret sharing scheme combined with verifiably reassured commitments, where none of the guardians know each other, and they are required to reach a certain threshold of agreement to combine their shares into an easily accessible password recovery key. The GAPM system supports multiple guardian sets, allowing participants to be added or removed, and there is no need to reissue all the shares each time users make a change. The user can also change the recovery threshold in real-time. Finally, the shares are further secured through the use of a post-quantum Key Encapsulation Mechanism (KEM) to ensure that, no matter what kind of attack (classical or quantum), the password recovery process will remain strong and secure.
An Elegant Privacy Preservation and De-Duplication Model With Elliptic Revocation Cryptography (PPD-ERC) Framework for Cloud Security L. Selvam, R. Gomathi, R. Venkatesan Transactions on Emerging Telecommunications Technologies, 2026 Due to the rapid advancement of communication technology, ensuring cloud data privacy and security is now regarded as one of the most important and difficult tasks. The traditional works are highly concentrated on creating cryptographic models for enhancing cloud system security. However, it encountered issues and problems because of the following factors: increased system overhead, time and storage requirements, complex mathematical operations, and ineffective data handling. In order to guarantee the security, privacy, and access control of cloud data sharing, the proposed work aims to develop a novel framework known as the Privacy Preservation and De‐duplication Model with Elliptic Revocation Cryptography (PPD‐ERC). This framework includes the entities of Cloud User (CU) (i.e., owner or receiver), Cloud Encryption Server (CES), sub‐CES, and Trusted Authority. Here, the lightweight ERC methodology encrypts user data using the private and public key pair. Then, the convergent keys are distributed to the blockchain, and the CU uses the Share algorithm for splitting the convergent keys. The CES validates the user authenticity based on the access controlling mechanism, which allows only the authorized users to obtain the data from server. Moreover, data de‐duplication is performed to avoid redundant encrypted data storage in the cloud system, and it increases the processing speed, minimizes the storage space, and optimizes the key generation process. During performance analysis, various evaluation metrics have been used to validate and compare the results of the proposed PPD‐ERC mechanism.
Temporal CAT-Based Data Fusion for IoMT System R. Venkatesan, A. Saravanan, A. Sathya Proceedings of the 12th International Conference on Biosignals Images and Instrumentation Icbsii 2026, 2026 IoMT (Internet of Medical Things) is purely real time series data operation where the temporal information plays the major role. Data fusion mechanisms represent a patient's complete information in a unique way that makes the prediction easier. But a patient's diagnosis always depends on their previous investigation and records, which need to be fused, and a decision has to be made based on that. Thus, the proposed work involves the temporal Cross Attention Fusion mechanism for unified representation of patient information using the current and last updated information. The proposed work utilizes the benefit of the Long Short-Term Memory (LSTM) based Variational Autoencoder (VAE) for obtaining meaningful information from the patient multi modal data. These features are then combined and fused along with the previously recorded patient information, that shown 96.2 % fusion effectiveness using the HER, Imaging and Sensor modalities dataset. The contribution for fusion is accounted for maximum by the image modality where the temporal-based fusion provided a balanced contribution by EHR and Sensor data.

With the exponential growth of the Internet of Things (IoT), ensuring real-time security in energy-constrained and environmentally sensitive environments has become a significant challenge. Traditional Intrusion Detection Systems (IDS), though effective, are often resource-intensive and unsuitable for deployment on low-power edge devices. This research explores the potential of Tiny Machine Learning (TinyML) to provide lightweight, on-device intelligence for threat detection. Research proposes a Gradient Boosting Based Adaptive Artificial Gorilla Troops (GraBoost-AAGT), which combines Adaptive Artificial Gorilla Troops Optimization (AAGTO) and Extreme Gradient Boosting (XGBoost), optimized for ultra-low power consumption and memory efficiency. Preprocessing involves categorical encoding and Z-score normalization, followed by Fast Fourier Transform (FFT) to extract relevant frequency-domain features. Specifically designed for embedded IoT systems, this model, referred to as GraBoost-AAGT, supports real-time detection of cyber threats, such as denial-of-service and probing attacks, while maintaining minimal central processing unit (CPU) and energy overhead. To evaluate performance, network traffic data encompassing both normal and malicious activities is collected using IoT intrusion detection dataset, traffic simulators, and replay tools under controlled attack and non-attack scenarios. Results demonstrate that GraBoost-AAGT deployed via TinyML achieves a high detection accuracy (99.50%), precision (99.8%), recall (99.12%), F1-score (99.45%), specificity (99.81%), and computation time (4.5s), reduced energy consumption, and lower CPU usage compared to traditional edge-based ML models. These findings confirm that TinyML offers a viable and sustainable solution for deploying intelligent threat detection in smart and green IoT ecosystems. This research provides a foundational step toward secure, scalable, and environmentally responsible IoT security frameworks.

Smart Digital Twin Ecosystem Powered by RETFound for Lung Cancer Diagnosis and Monitoring Golden Nancy, R. Venkatesan, K Ramalakshmi 2025 5th Asian Conference on Innovation in Technology Asiancon 2025, 2025 The advancement of medical foundation models such as RETFound, a repurposed vision transformer pre-trained on large-scale radiological data, opens new avenues for precision oncology. This study proposes a novel Smart Digital Twin Ecosystem (SDTE) that integrates RETFound with a multi-modal patient-specific digital twin to enable personalized diagnosis, real-time monitoring, and therapeutic planning for lung cancer. The architecture combines high-resolution thoracic CT scans, histopathology, genomic variants of EGFR, ALK, KRAS, and longitudinal clinical records to dynamically simulate tumor evolution and patient response. RETFound was fine-tuned on an internal lung cancer dataset comprising 8,420 annotated CT studies from LIDC-IDRI and 2,135 histopathology samples from TCGA-LUAD and TCGA-LUSC. The proposed system achieved an average accuracy of 98.16%, Sensitivity of 97.92%, Specificity of 97.53%, Recall of 90.23% and F1-score 0.95. The model achieved a Dice Similarity Coefficient (DSC) of 0.894 for 3D tumor segmentation, an AUC-ROC of 0.976 for malignancy classification, and a Pearson correlation of 0.832 between predicted tumor volume trajectories and actual longitudinal growth patterns. The Digital Twin Layer incorporates a spatiotemporal attention module fused with RETFound embeddings and genomics-informed Graph Convolution Networks (GCNs) to simulate individualized tumor progression under multiple treatment regimens. The SDTE supports clinical decision-making by generating counterfactual treatment outcomes, allowing oncologists to compare radiotherapy vs. immunotherapy scenarios in silico. The proposed results validate the synergistic potential of RETFound and digital twin technology in reshaping lung cancer care through continuous, predictive, and personalized insights.
