1. Tamper Detection Definition
Tamper Detection refers to the ability to detect any unauthorized changes or alterations made to a document or electronic signature after it has been signed. Tamper detection mechanisms use cryptographic techniques to verify the integrity of the document and ensure that it has not been modified since the signature was applied. This ensures that the document remains legally valid and trustworthy.
2. Why Is Tamper Detection Important?
- Document Integrity: Tamper detection ensures that the document has not been altered after signing, preserving its legal validity and trustworthiness.
- Security: It helps protect documents from unauthorized modifications, ensuring that the signed content remains unchanged and secure.
- Compliance: Many eSignature regulations, such as eIDAS and the ESIGN Act, require tamper detection mechanisms to maintain the enforceability of electronic signatures.
- Non-Repudiation: Tamper detection provides proof that the document has not been altered, ensuring that the signer cannot deny having signed it or claim that it was modified post-signature.
3. Key Components of Tamper Detection
- Cryptographic Hashing: A hash value is generated when the document is signed. Any changes to the document would alter the hash, indicating tampering.
- Digital Signatures: The use of digital signatures helps detect unauthorized modifications by comparing the current document’s hash with the original hash at the time of signing.
- Audit Trails: The signing platform records all actions related to the document, allowing for detection of any unauthorized changes after the document has been signed.
- Document Versioning: If tampering is detected, previous versions of the document can be compared with the altered version to identify discrepancies.
