Abstract
An apparatus and system for authenticating features for download to an image scanning apparatus has a client computing device generate an image of a symbol that encodes authentication data. The client computing device hashes a communication parameter of its transceiver, digitally signs the hash value with a private key from public-private key pair, and encodes the hash value, digital signature and the unencrypted communication parameter into the symbol. The image scanning apparatus captures an image of the symbol, decodes the symbol, verifies whether the unencrypted communication parameter corresponds to the hash of the communication parameter, and a public key stored in the memory of the barcode reader corresponds with the private key used to sign the hash value. If the communication parameter corresponds with the hash value and the signature corresponds with the public key, the barcode reader enables its transceiver to download the feature from the client computing device.
