Abstract: A method for reversible image data hiding includes steps of encrypting an original image by an encryption process to generate an encrypted image, embedding a message into the encrypted image by an embedment process to generate an embedded image, and extracting the message and the original image from the embedded image by a decryption and extraction process. The encryption process includes generating a key stream by using a secret encryption key, and generating an encrypted image by XORing the original image with the key stream. The embedment process includes generating an embedded image by embedding the message via XORing the encrypted image with a predetermined public key set.

Abstract: The application of egg yolk oil, as well as benzopyrene-eliminated egg yolk oil, is prepared for medicaments for the treatment of allergic rhinitis. By topical application of egg yolk oil in the nasal cavity, symptoms of allergic rhinitis could be improved significantly. After topical treatment with egg yolk oil, levels of inflammatory cytokines IL-4 and IgE antibodies in lymphocytes of model mice with allergic rhinitis may be reduced. The method discloses a new application of egg yolk oil for the treatment of allergic rhinitis. In order to avoid the presence of residual benzopyrene (which is potentially carcinogenic) in egg yolk oil extracted by heating yolk, the method prepares a medicament for treating allergic rhinitis with benzopyrene-eliminated egg yolk oil, thereby avoiding the potential carcinogenic risk of benzopyrene residue.
