Secure data fingerprinting and immutable data storage using an application-specific distributed ledger

A computer-implemented method, comprising:

• receive an application programming interface (API) data structure that comprises a digital fingerprint for digital data associated with a client device event;
• aggregating the digital fingerprint with one or more other digital fingerprints to generate an aggregated digital fingerprint data structure that maps the digital fingerprint and the one or more other digital fingerprints via a hierarchical tree structure;
• generating a hash data structure based at least in part on the aggregated digital fingerprint data structure;
• adding the hash data structure to an application-specific distributed ledger based at least in part on a validation rule set that defines a domain-specific data schema for the application-specific distributed ledger;
• storing the aggregated digital fingerprint data structure in an object-relational database;
• and
• generating an output associated with the digital fingerprint based at least in part on (i) the hash data structure added to the application-specific distributed ledger and (ii) the aggregated digital fingerprint data structure stored in the object-relational database.

A computer program product comprising at least one non-transitory computer readable storage medium having computer executable code portions stored therein, the computer executable code portions comprising program code instructions configured to:

• receive an application programming interface (API) data structure that comprises a digital fingerprint for digital data associated with a client device event;
• aggregate the digital fingerprint with one or more other digital fingerprints to generate an aggregated digital fingerprint data structure that maps the digital fingerprint and the one or more other digital fingerprints via a hierarchical tree structure;
• generate a hash data structure based at least in part on the aggregated digital fingerprint data structure;
• add the hash data structure to an application-specific distributed ledger based at least in part on a validation rule set that defines a domain-specific data schema for the application-specific distributed ledger;
• store the aggregated digital fingerprint data structure in an object-relational database;
• and
• generate an output associated with the digital fingerprint based at least in part on (i) the hash data structure added to the application-specific distributed ledger and (ii) the aggregated digital fingerprint data structure stored in the object-relational database.
