Augmenting and Updating Data Using Encrypted Machine-Readable Identifiers

摘要

Disclosed are various embodiments for augmenting and updating content data using encrypted machine-readable identifiers. A client application may be employed to transfer a first amount of data to a reader device using a first machine-readable identifier, where the reader device has access to at least one cryptographic key capable of decrypting the data. If the first amount of data is modified or augmented on the reader device, the client application may capture an image of a second machine-readable identifier generated by the reader device, decode and decrypt the machine-readable identifier to identify a second amount of data, and reconcile differences between the first amount of data and the second amount of data.

主权项

1. A system, comprising:
a client device comprising at least one hardware processor; a client application executable in the client device comprising program instructions that, when executed, cause the client device to:
generate a first machine-readable identifier using a first amount of data encrypted using at least one cryptographic key for rendering in a display of the client device, wherein a reader device having the at least one cryptographic key stored thereon is configured to decrypt the data;identify a second machine-readable identifier in at least one image captured by the client device;decode the second machine-readable identifier to identify a second amount of data encrypted by the reader device using the at least one cryptographic key;decrypt the second amount of data using the at least one cryptographic key; andidentify whether a conflict exists between the first amount of data and the second amount of data.
