Operational value
Clear accountability across organisational handoffs
IBDCP architecture
Verifiable data custody
Data custody describes who controlled a record, under which authority, during each meaningful transition. IBDCP preserves custody evidence across systems so organisations can establish accountable handling without centralising every source record.
The business problem
When records cross teams, vendors, clouds or ledgers, audit trails fragment. Copies may remain valid business inputs while their handling history becomes difficult to prove.
How IBDCP addresses it
IBDCP binds custody transitions to authorised identities, timestamps, policy decisions and integrity evidence. Sensitive payloads can remain in controlled off-chain stores while proofs reference their verified state.
Register the governed record or event
Verify the current custodian and authority
Record an approved custody transition
Retain integrity proof and retrieval references

Trust value
Stronger dispute and audit evidence
Architecture value
Private-by-design separation of payload and proof
Security and governance boundary
Custody evidence cannot compensate for unlawful collection or poor retention practices. Data owners remain responsible for access, minimisation and deletion obligations.
Implementation evidence
IBDCP Sign keeps documents private while preserving evidence of signer action and integrity; healthcare workflows apply the same principle to sensitive patient records.
