Abstract

Systems and methods for source chain management with identity-based tokens and enhanced security are disclosed. A processing system receives input that includes a decentralized identifier (DID) uniquely associated with an entity. The processing system invokes a smart contract deployed on a distributed ledger to mint a non-transferable identity-based token permanently linked to the DID. Metadata generated for the token includes cryptographic references to a hierarchical source chain structure stored in a decentralized data storage system, along with cryptographic verification data. Events associated with the DID are memorialized by appending granular event details, including timestamps, data changes, and origin identifiers, into the hierarchical source chain. Authorized access to event details and tokens is provided via an authenticated interface that securely retrieves and reconstructs encrypted data shards distributed across decentralized nodes, enhancing data security, immutability, and verifiability in decentralized environments.

Dependent claims

A computing system, comprising:

a processing system comprising one or more processors configured to:
receive, from an entity, an input comprising a decentralized identifier (DID) uniquely associated with the entity;
invoke a smart contract deployed on a distributed ledger to mint a non-transferable identity-based token linked permanently to the DID, wherein the token cannot be transferred to another DID;
generate metadata for the identity-based token comprising:
a cryptographic reference to a hierarchical source chain structure stored within a decentralized data storage system;
and
cryptographic verification data configured to validate integrity of the metadata and the hierarchical source chain structure;
store the metadata and a link to the identity-based token in the decentralized data storage system, wherein the decentralized data storage system partitions data into a plurality of encrypted data shards and distributes each encrypted data shard across decentralized storage nodes;
memorialize an event associated with the entity by:
recording granular event details comprising a timestamp, a comprehensive log documenting specific data changes, and an origin identifier of the event;
and
appending the granular event details into the hierarchical source chain structure stored within the decentralized data storage system;
verify integrity of the hierarchical source chain structure by validating cryptographic links between event records;
and
provide authorized access through an authenticated interface to reconstruct data from encrypted shards stored in the decentralized data storage system,
wherein reconstructing the data from the encrypted shards comprises:
retrieving encrypted shards referenced by the metadata from the decentralized storage nodes;
decrypting the encrypted shards using one or more decryption keys derived from the DID;
reconstructing a data object by assembling at least a subset of the decrypted shards;
and
presenting the reconstructed data object to authorized entities.
