US Patent 10970378 Secure generation and verification of machine-readable visual codes

Disclosed embodiments relate to systems and methods for securely generating verifiable machine-readable visual codes. Techniques include identifying a data element to be made available to a computing device, generating a machine-readable visual code including the data element, making available the generated machine-readable visual code to a display medium, such that the generated machine-readable visual code can be decoded from the display medium to yield the data element and can be validated. The computing device's ability to interact with the data element may be conditioned on the validation of the data element being successful.
