Block lightweight encryption scheme for securing internet of things data and information Esau Taiwo OLADIPUPO, David Olalekan OLAYEMI, Christiana Oluwakemi ABIKOYE, Abidemi Emmanuel ADENIYI, Oluwasegun Julius AROBA, Joseph Bamidele AWOTUNDE Systems and Soft Computing, 2026 Healthcare Internet of Things (HIoT) systems increasingly process multimedia data, yet existing Lightweight Cryptosystems (LWCs) often provide insufficient confusion, diffusion, and security due to their short key and block sizes. These limitations also expose them to key-related attacks and Cipher Block Chaining (CBC) eroding. To address these challenges, this work proposes a new multimedia-oriented LWC in which only a single block is encrypted or decrypted, significantly reducing computational overhead. Elliptic Curve Diffie–Hellman (ECDH) is employed for key establishment, and a dedicated Image_XOR module—combining secure pseudorandom number generation with XOR operations—is designed to enhance confusion, diffusion, and nonlinearity. The scheme applies SHA-256 to the concatenated bytes of the Shared Secret Key (SSK) and the plain image to generate a hash value (hashval). The plain image, SSK, and hashval are processed through the Image_XOR module to produce the encrypted image, while hashval is further encrypted using a Modified Caesar cipher (MCaesar). Decryption reverses the operations using the corresponding MCaesar_Dec module. Comprehensive evaluations—including sensitivity, statistical analyses, and noise-attack resistance—demonstrate that the proposed LWC exhibits strong robustness, high key and plaintext sensitivity, and superior performance relative to classical LWC designs. Its very low processing time and reduced memory footprint indicate suitability for real-time deployment on resource-constrained IoT devices. Overall, the findings confirm that the proposed LWC achieves strong security with minimal resource consumption, making it highly suitable for modern HIoT environments.

Federated Learning Augmented with Convolutional Neural Networks for Brain Cancer Classification Joseph Bamidele Awotunde, Christiana Oluwakemi Abikoye, Biswajit Brahma, Esau Taiwo Oladipupo, Anjan Bandyopadhyay Procedia Computer Science, 2025 Leveraging MRI images for the categorization of brain tumors is a critical yet complex endeavor within the realm of medical imaging. Precise identification is crucial for prompt and effective treatment; however, the intricate nature of tumor morphology and variability in imaging often pose obstacles. Traditional practices largely rely on the manual examination of MRI images, supplemented by classic machine learning (ML) strategies. However, these techniques typically lack the robustness and scalability necessary for precise and automated tumor categorization. Key challenges include extensive manual processing, vulnerability to human error, limited ability to handle voluminous datasets, and insufficient adaptability to diverse tumor forms and imaging scenarios. To address these challenges, this paper introduces the use of federated learning, a ML-based model that integrates data from various entities, coupled with Convolutional Neural Networks (CNNs) for the classification of brain cancer. Federated learning facilitates the decentralized training of models across numerous clients while preserving the confidentiality of data, thus meeting the critical demand for privacy in the management of medical data. The model’s design incorporates transfer learning and a pre-trained CNN to refine its performance on the brain tumor dataset. The empirical evidence suggests that this integrated approach surpasses conventional techniques in the precise classification of brain cancer types. These insights underscore the promise of federated learning in conjunction with CNNs for medical image analysis, particularly in diagnosing brain cancer. This methodology could enhance the precision and efficiency of cancer classification, leading to improved treatment strategies and, ultimately, better patient care outcomes.
Secured textual medical information using a modified LSB image steganography technique Roseline Oluwaseun Ogundokun, Oluwakemi Christiana Abikoye, Ezekiel Adebayo Ogundepo, Akinbowale Nathaniel Babatunde, Abdul Rahman Tosho Abdulahi, Aditya Kumar Sahu Securing the Digital World A Comprehensive Guide to Multimedia Security, 2025 Health professionals are increasingly concerned with the welfare of their patients and the security of their medical records. With the shift toward electronic methods for obtaining and recording patient information, these records have become more vulnerable to cyberattacks. Ensuring that unauthorized individuals do not gain access to sensitive medical information is paramount. This chapter aims to enhance the security of textual medical records using an improved least significant bit (LSB) steganography technique. The objective is to develop a robust medical information system that secures patient data against potential cyber threats by implementing a modified LSB procedure called circular shift LSB steganography. The proposed system was developed and programmed in the MATLAB 2018a environment. The enhancement involved rational bit shift operations to improve the traditional LSB steganography method. The performance of the modified LSB technique was assessed using key metrics such as peak signal-to-noise ratio (PSNR), mean squared error (MSE), and the number of shifts. The modified LSB method demonstrated superior performance compared to traditional LSB methods. Quantitative analysis revealed PSNR values ranging from 74.3458 to 80.364, indicating higher image quality and reduced distortion. MSE values ranged from 0.002391 to 0.000598, showing minimal error and high fidelity of the stego images. Additionally, the number of shifts used in the embedding process ranged from 32,640 to 88,410, enhancing the security and robustness of the stego images. The enhanced LSB steganography technique, employing rational bit shift operations, outperformed traditional LSB methods regarding robustness, capacity, and imperceptibility. The introduction of the number of shifts as a new output measure further validated the improved security and effectiveness of the proposed method. The results confirm that the updated LSB technique provides a more secure solution for protecting textual medical records against unauthorized access and cyber threats. Future research should explore further optimization of the bit shift operations to enhance the security and efficiency of the LSB steganography technique. Additionally, expanding the application of this method to other types of sensitive data and evaluating its performance in different environments and scenarios will help establish its broader utility and effectiveness.
Detection and Classification of Potato Leaves Diseases Using Convolutional Neural Network and Adam Optimizer Shakirat Aderonke Salihu, Sunday Olamilekan Adebayo, Oluwakemi Christiana Abikoye, Fatima Ehenezie Usman-Hamza, Modinat Abolore Mabayoje, Biswajit Brahma, Anjan Bandyopadhyay Procedia Computer Science, 2025 This study explores the development of a Convolutional Neural Network (CNN) with Adam Optimizer for detecting potato leaf blight, a critical concern in agriculture due to the economic importance of potatoes. The research focuses on developing a highly accurate model to distinguish between healthy and diseased potato leaves using image data. Key steps include dataset collection, image preprocessing with scaling, augmentation, and normalization, and the construction of a CNN architecture featuring convolutional, max-pooling, dense layers, and dropout regularization. The model’s performance, evaluated through accuracy, precision, recall, and F1-scores derived from confusion matrix analysis, achieved an impressive 96.88% accuracy. Specific detection metrics include 0.76 precision, 0.93 recall, and 0.84 F1-score for healthy leaves, and near-perfect scores for Late and Early Blight detection. The findings underscore the efficacy of CNNs combined with Adam optimization in agricultural disease diagnosis, offering a reliable tool for early potato leaf blight detection.
A Lightweight Image Cryptosystem for Cloud-Assisted Internet of Things Esau Taiwo Oladipupo, Oluwakemi Christiana Abikoye, Joseph Bamidele Awotunde Applied Sciences Switzerland, 2024 Cloud computing and the increasing popularity of 5G have greatly increased the application of images on Internet of Things (IoT) devices. The storage of images on an untrusted cloud has high security and privacy risks. Several lightweight cryptosystems have been proposed in the literature as appropriate for resource-constrained IoT devices. These existing lightweight cryptosystems are, however, not only at the risk of compromising the integrity and security of the data but also, due to the use of substitution boxes (S-boxes), require more memory space for their implementation. In this paper, a secure lightweight cryptography algorithm, that eliminates the use of an S-box, has been proposed. An algorithm termed Enc, that accepts a block of size n divides the block into L n R bits of equal length and outputs the encrypted block as follows: E=L⨂R⨁R, where ⨂ and ⨁ are exclusive-or and concatenation operators, respectively, was created. A hash result, hasR=SHA256P⨁K, was obtained, where SHA256, P, and K are the Secure Hash Algorithm (SHA−256), the encryption key, and plain image, respectively. A seed, S, generated from enchash=Enchashenc,K, where hashenc is the first n bits of hasR, was used to generate a random image, Rim. An intermediate image, intimage=Rim⨂P, and cipher image, C=Encintimage,K, were obtained. The proposed scheme was evaluated for encryption quality, decryption quality, system sensitivity, and statistical analyses using various security metrics. The results of the evaluation showed that the proposed scheme has excellent encryption and decryption qualities that are very sensitive to changes in both key and plain images, and resistance to various statistical attacks alongside other security attacks. Based on the result of the security evaluation of the proposed cryptosystem termed Hash XOR Permutation (HXP), the study concluded that the security of the cryptography algorithm can still be maintained without the use of a substitution box.
Ethnicity and Biometric Uniqueness: Iris Pattern Individuality in a West African Database John Daugman, Cathryn Downing, Oluwatobi Noah Akande, Oluwakemi Christiana Abikoye IEEE Transactions on Biometrics Behavior and Identity Science, 2024 We conducted more than 1.3 million comparisons of iris patterns encoded from images collected at two Nigerian universities, which constitute the newly available African Human Iris (AFHIRIS) database. The purpose was to discover whether ethnic differences in iris structure and appearance such as the textural feature size, as contrasted with an all-Chinese image database or an American database in which only 1.53% were of African-American heritage, made a material difference for iris discrimination. We measured a reduction in entropy for the AFHIRIS database due to the coarser iris features created by the thick anterior layer of melanocytes, and we found stochastic parameters that accurately model the relevant empirical distributions. Quantile-Quantile analysis revealed that a very small change in operational decision thresholds for the African database would compensate for the reduced entropy and generate the same performance in terms of resistance to False Matches. We conclude that despite demographic difference, individuality can be robustly discerned by comparison of iris patterns in this West African population.
