eContract & Digital Signature

Preserve contracts, signatures and validation material after the signing workflow closes.

Problem and records to preserve

Years later, certificate paths and status material needed for signature validation may be missing.

SYNTHETIC CASE

Synthetic signed-contract case

SIGN-SYN-001
ElementIllustrative scope
Decision makers / usersLegal teams, contract operations and signing-platform owners
Source systemeContract / signing platform
RevisionByte changes create another revision; detached signatures must bind the correct document.
Record relationshipA post-signing amendment is a new linked object, never altered old bytes.

Sector-specific record journey

01

Finish signing

Await signing-session closure and identify the final set; exclude in-progress drafts.

02

Freeze bytes

Freeze signed bytes, detached signatures and attachments with signing transaction/revision IDs.

03

Collect material

Collect authorized certificates, status data and existing timestamps; identify missing material.

04

Preserve

Submit under agreed custody and retain archiveId/jobId/evidence history; no retrospective-proof claim.

05

Export with authority

Export the authorized contract/revision; subsequent amendments are new linked objects.

Delivered artifacts

RecipientArtifact
Source systemIntake receipts, source/revision-to-archiveId/jobId mappings and per-item errors.
Package recipientContract/annex set, revision relationships and authorized validation material.
Record owner / operationsCompleted/outstanding inventory, applied decisions and report references; no automatic legal conclusion.

Rights, retention and deployment

Signatory status does not grant every user export rights.

Preservation evidence does not automatically convert signatures to PAdES-LTA or CAdES-LTA; signature-specific processing needs its own scope.

Retention authority and exit

The owner must approve the retention authority and trigger for this record class: Signing workflow ends and documents/validation material are handed over.

Sample dossier and tests

Synthetic text files exercise inventory and hashing; they are not signed contracts, real records or ERS/XMLERS.

Download synthetic dossier
TestExpected outcome
IntactFile inventory, size and SHA-256 match the manifest.
Missing / changed bytesThe verifier rejects the package without claiming inventory success.
Sector business caseMissing detached signatures or annexes must appear in inventory findings.

Scope a PoC for this dossier

Test detached signatures, missing attachments and incomplete status material; reports must give reasons instead of blanket validity.

Finalization point and specific acceptance

Control pointRequirement
Source eventSigning workflow ends and documents/validation material are handed over.
Revision / decisionByte changes create another revision; detached signatures must bind the correct document.
Test and expected resultA signature from another transaction or changed annex cannot yield successful verification.

Sample inventory/hashing checks bytes only. Authorization, decision and state cases must run in the provisioned test environment before business acceptance.
