Abstract

See full text

Implementations of the present disclosure are directed to sharing data in a supply chain, the data corresponding to an item having a tag associated therewith. Methods include determining a random number from the tag, the random number being unique to the item, selecting a first integer and a second integer, generating a first public key based on the first integer and a semi-public key based on the second integer, generating an identifier based on the first public key and the random number, generating a key based on the semi-public key and the random number, encrypting the data using the key to provide encrypted data, defining a tuple comprising the identifier and the encrypted data, and transmitting the tuple over a network for storage in a persistent storage device.
