Security overview

Secure document sharing with built-in proof.

BlinkSeal is built for confidential legal, HR, and compliance workflows where teams need controlled delivery, reliable access tracking, and audit-ready proof.

Private storage by default

Documents remain in private storage and are never served from public object URLs. Public viewers access files only after the viewer route validates the secure token server-side.

Signed URL access

After validation, BlinkSeal issues a short-lived signed URL. Revoked, expired, invalid, or blocked links show a clean unavailable state instead of exposing file details.

Access proof

Every document can include a live Access Proof page showing who opened it, when, from where, and on what device.

  • File status
  • Opens and downloads
  • IP and device
  • Local and UTC timestamps
  • Immutable audit timeline

Audit exports

BlinkSeal generates verifiable proof records with document hashes, event history, and certificate-ready evidence bundles for legal and IT review.
