Abstract
Systems and methods are provided for encrypting and decrypting data using visually encoded ciphertext. The method includes selecting, using a graphical user interface coupled to an electronic device, one or more portions of a document to be encrypted, visually encoding the selected one or more portions of the document, generating a visual representation, wherein the visual representation corresponds to encrypted content, and replacing the selected one or more portions of the document with the visual representation. The method further includes displaying, to the user, the visual representation, capturing the visual representation using one or more cameras, decoding the visual representation, obtaining the encrypted content, and decrypting the encrypted content, generating decrypted content.
