Borderly Authorized Record Verification
Verify residency records shared with you via a secure, time-limited token. Access is granted only by the record owner or their authorized representative. All records are cryptographically chained and independently timestamped.
How Verification Works
1. Record Collection
Device captures location data and creates a presence record with timestamp and metadata.
View records →2. Hash Chain
Each record's SHA-256 hash includes the previous record's hash, creating a tamper-evident chain.
View chain →3. RFC 3161 Timestamp
An independent Timestamp Authority (DigiCert) certifies when each record was created. Verifiable with OpenSSL.
Verify timestamps →4. Blockchain Anchor
Merkle roots of records may be anchored on the Polygon blockchain for immutable, publicly verifiable proof of existence.
View anchors →Trustless Verification
Every record can be independently verified using standard cryptographic tools. RFC 3161 timestamps are issued by DigiCert's public Timestamp Authority and can be verified with openssl ts -verify. Blockchain anchors, available on the Certify plan, are publicly visible on the Polygon blockchain.
Enter Verification Token
Paste the token you received from the record owner or their attorney. No records are accessible without a valid token.
Tokens are time-limited and scoped to specific data. They cannot be reused after expiration.
