ecured Locktera files are immutable. This means once your data is secured, it cannot be altered, deleted, or tampered with without leaving an evident trace. This characteristic is critical for maintaining data integrity and ensuring that records remain authentic and trustworthy over time.

How Does Locktera Use Immutability?

1. Immutable Ledger Systems:

   • Locktera leverages an immutable ledger system to ensure that critical data stored within its platform remains tamper-proof. The inherent immutability makes it impossible to alter the contents once it has been secured.

   • Every piece of data, whether it’s a transaction or a document, is assigned a unique cryptographic hash that securely ties it to its associated record. Once the data is stored, the cryptographic hash ensures that any attempt to modify it would require altering the entire sequence of linked records, making tampering virtually impossible.
     

2. Audit Trails and Logs:

   • Locktera creates immutable audit trails for all actions taken within the platform. Every action, change, or access to data is recorded in a log that cannot be modified or deleted.

   • This allows Locktera to provide non-repudiation—meaning users cannot deny their actions—and ensures that any potential issues can be traced back to the original source without any risk of manipulation.
     

3. Digital Signatures and Cryptographic Digests:

   • Locktera uses digital signatures and cryptographic digests to ensure that data, once signed or hashed, cannot be altered without invalidating the signature or digest. The integrity of data is ensured, and its immutability is guaranteed by the fact that any change would result in a mismatch between the original and recalculated digests.
     

4. Cryptographic Hashing for Integrity Checks:

   • Hashing algorithms are used by Locktera to generate unique digests of the data. When data is written to storage or transmitted, its corresponding hash is stored or transmitted alongside it. The hash acts as an immutable fingerprint of the data—ensuring that it cannot be tampered with without detection.
     

5. Compliance and Regulatory Requirements:

   • For industries that require strict adherence to regulations like HIPAA, GDPR, and others, immutability is key. Locktera ensures that all regulatory-compliant data is recorded and stored in an immutable format, preventing unauthorized changes to sensitive records and providing a robust audit trail for compliance purposes.

What does immutability mean to you?

• Data Security: You prevent unauthorized modifications, ensuring your data remains in its original form.

• Trust: Immutability guarantees that your data stays consistent and reliable, which is essential for both your internal systems and client-facing services.

• Auditability: You can create verifiable and irreversible records, supporting detailed audits and investigations.

• Regulatory Compliance: Many industries require you to preserve original data for legal and compliance purposes, and immutability ensures you meet those requirements.
