Firefly Algorithm for Optimization of Scaling Factors During Embedding of Manifold Medical Information: An Application in Ophthalmology Imaging

摘要

Augmented influence of globalization in the medical domain is quite noticeable and is very much evident from the modern medical approaches. Exchanging medical information using communication technologies to provide health care services for mutual availability of therapeutic case studies amongst various diagnostic centers or hospitals is a very common practice. In this present work, a novel approach is proposed to design a robust biomedical content authentication system by embedding multiple logo of the hospital or multiple electronic patient record (EPR) within the retinal image by means of combined discrete wavelet transformation--discrete cosine transformation--singular value decomposition (DWT-DCT-SVD) based approach of watermarking teamed with firefly algorithm (FA). One of the modern nature-inspired meta-heuristic algorithms required for optimization is firefly algorithm. This algorithm is used to find the best possible scaling factors for embedding. It is evident from the results that the proposed method can prove to be an accurate authentication system for information exchange along with high level of robustness, imperceptibility, and payload.
