MUMBAI, India, Jan. 9 -- Intellectual Property India has published a patent application (202511114525 A) filed by Madan Mohan Malaviya University Of Technology, Gorakhpur, Uttar Pradesh, on Nov. 20, 2025, for 'an image plagiarism detection system.'
Inventor(s) include Dr. Satvik Vats; Dr. Harish Chandra; Shivam Rai; and Priya Singh.
The application for the patent was published on Jan. 9, under issue no. 02/2026.
According to the abstract released by the Intellectual Property India: "The invention provides an intelligent, multi-engine image plagiarism detection system designed to identify exact, transformed, and partially copied images across diverse sources. The system extracts images from documents, preprocesses them through normalization and noise removal, and filters irrelevant graphic elements. A hybrid feature extraction engine integrates convolutional neural network embeddings, Vision Transformer embeddings, perceptual hashing, and histogram descriptors to capture both local textures and global semantics. Candidate images are retrieved through parallel searches across online reverse image search APIs, local repositories, and vector-based clustering systems. Similarity computation uses structural similarity, perceptual hash distance, and cosine similarity of embeddings, fused through weighted averaging. For high-scoring matches, a localization module performs patchwise comparison and generates heatmaps highlighting plagiarized regions. A decision engine assigns plagiarism labels and generates detailed reports, while a feedback loop refines system performance over time. The invention delivers robust, scalable, and explainable image plagiarism detection."
