Method and system for establishing digital identity in international trade
A method for establishing a digital identity includes: receiving, by a receiver of a processing server, at least an identification value from a first computing system; identifying, by a processor of the processing server, a verification authority based on the identification value; transmitting, by a transmitter of the processing server, at least the identification value to a second computing system, where the second computing system is associated with the identified verification authority; receiving, by the receiver of the processing server, a positive verification indicating authenticity of the identification value; standardizing, by the processor of the processing server, the identification value; and publishing, by the transmitter of the processing server, the standardized identification value using a third computing system.

receiving, by the receiver of the processing server, a positive verification indicating authenticity of the identification value;
standardizing, by the processor of the processing server, the identification value, ensuring uniformity among identification values used in the network system, wherein the standardizing includes (i) formatting, by the processor of the processing server, the standardized identification value into a standardized identification data structure including a data type field, an issuing entity field, the identification value as defined data fields, and (ii) partitioning, by the processor of the processing server, the standardized identification data structure into a public portion and a private portion, and encrypting the private portion;
after partitioning the standardized identification data structure, hashing, by the processor of the processing server, the standardized identification value in the standardized identification structure via application of a one-way hashing algorithm thereto; and
after hashing the standardized identification value, publishing, by the processing server, the hashed and standardized identification value a to a block of a blockchain in a blockchain node in a blockchain network including a plurality of blockchain nodes, wherein the blockchain node generates the block including a block reference value corresponding to a hash of a previous block header, and a data reference value corresponding to a root of a Merkle tree generated using one or more data values of the block, and wherein modification of the hashed standardized identification value requires regeneration of the data reference and the block reference value in each subsequent block of the blockchain.
