Abstract
Disclosed embodiments relate to systems and methods for securely verifying encoded visual codes together with network address information. Techniques include: obtaining a first capture of a visual display, the visual display being generated on a display medium; applying a display detection technique based on the obtained first capture; determining, based on the display detection technique, whether a boundary of the display medium is identified; identifying, within the first capture, an encoded visual representation of a data element and a network address; determining whether the network address is valid; and determining whether to validate the encoded visual representation based on the determination of whether the network address is valid.
