Overall, people with diabetes have a higher risk of developing different infectious diseases and demonstrate increased mortality. Type 2 diabetes mellitus (T2DM) is a significant risk factor for COVID-19 progression and its severity, poor prognosis, and increased mortality. How diabetes contributes to COVID-19 severity is unclear; however, it may be correlated with the effects of hyperglycemia on systemic inflammatory responses and immune system dysfunction. Using the envelope spike glycoprotein SARS-CoV-2, COVID-19 binds to angiotensin-converting enzyme 2 (ACE2) receptors, a key protein expressed in metabolic organs and tissues such as pancreatic islets. Therefore, it has been suggested that diabetic patients are more susceptible to severe SARS-CoV-2 infections, as glucose metabolism impairm...

Digital steganography uses some digital media as the cover for the secret message, like in our case, we have used digital images as the cover media. Essence of steganography is that the third party should never be able to detect the presence of secret message in the cover image. Once the third party detects the secret message, it is assumed that the steganography technique has failed to serve its purpose. The proposed model presents a novel approach of develop a secure data hiding technique of Steganography using wavelet transform, Some logical operations, binary convertor, along with random number generation method. Keywords— Digital image, information hiding, steganography, PSNR value, LSB.
