This paper proposes a scheme for detachable reversible data hiding in image encryption. In which the sender encrypts an image using encryption key. Then, the data is appended to the encrypted image using a data-hiding key. With an encrypted image containing additional data, if a receiver has the data-hiding key, he can extract the additional data though he does not know the content of the image. If the receiver has the encryption key, he can decrypt the encrypted image and get an image similar to the original one, but he cannot extract the additional data. If the receiver has both the data-hiding key and the encryption key, he can extract the additional data and recover the original image without any error.
Introduction: Their unique size-dependent properties make these materials superior and indispensable in many areas of human activity. Selenium possesses excellent photo electrical and semiconductor properties which make it extensively used in duplicate, photography, cells and rectifiers. Selenium is also one of essential trace elements in the human body and has great importance in nourishment and medicine. In India, medicinal plants are widely used by all sections of people either directly as folk remedies or in different indigenous systems of medicine or indirectly in the pharmaceutical preparations of modern medicines. The aim of the present study is to determine antimicrobial activity of selenium nanoparticles and Pterocarpus santalinus based mouthwash.
Materials and Methods: Antimicrobial activity of respective nanoparticles against the strain staphylococcus aureus, Bacillus and E Coli. MH Aagar was utilized for this activity to determine the zone of inhibition. Muller hinton agar was prepared and sterilized for 45 minutes at 120 lbs. Media poured into the sterilized plates and let them stabilize for solidification. The wells were cut using the well cutter and the test organisms were swabbed. The nanoparticles with different concentrations were loaded and the plates were incubated for 24 hours at 37 degree celsius. After the incubation the zones of inhibition were measured.
Results: The highest zones of inhibition were exhibited against two bacterial strains Staphylococcus aureus and Staphylococcus mutans proving that it acts as a good antibacterial against S.aureus and S.mutans infections.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
