Method and system for obfuscating senstive personal data in processes requiring personal identification in unregulated platforms

A networked system comprising:

• a third-party service platform having a first server at least partially administering access to services, said services obtained subject to receipt of authenticated personal data of a client and subsequent to supply of log-in data for the client, wherein said log-in data is receivable via a user interface through which a unique address of a first digital wallet of the client is obtained;
• an unregulated trading platform remote to the third-party service platform, the unregulated trading platform having a public server and a public ledger database in which is stored a plurality of unique wallet addresses including that of the first digital wallet and wherein the first digital wallet contains one or more non-transferable non-fungible tokens “NFTs” locked to the first digital wallet and wherein each non-transferable NFT was minted from a regulated platform to which there is a record in the public ledger database;
• a network providing a communication backbone through which the first server communicates with the public server and to obtain access to information stored in the first digital wallet;
• and
• wherein the first server is arranged:
• through message interaction over the network with the public server, to search for a record of specific personal data in the public ledger database to locate non-transferable NFT's stored in the first wallet and related to the specific personal data, and
• through message interaction over the network, to receive at least one encoded certificate within a relevant non-transferable NFT, from the first wallet, related to the specific personal data;
• and
• to provide access to the services based on receipt of the at least one encoded certificate that verifies authenticity of the specific personal data through association of the at least one encoded certificate with the regulated platform.
