US Patent 10387577 Secure data translation using machine-readable identifiers

Disclosed are various embodiments for providing secure data translation using machine-readable identifiers, such as barcodes or quick response (QR) codes. A client device may be configured to translate input data stored in a first data format to data in a universal data format and encrypt the data in the universal data format using the cryptographic key such that the data in the universal data format is only accessible by the reader device having the cryptographic key. The client device may further generate a machine-readable identifier using the data as encrypted for rendering in a display accessible by the client device. A reader device may be configured to decrypt the data as encrypted to access the data in the universal data format, and translate the input data from the universal data format to a second data format in accordance with a second format setting.
