Sensitive documents need real signatures
PDF files are vulnerable
A standard PDF can be opened, changed, and saved without leaving a trace. Even if it’s “signed.” A Foxit study found that 61% of users don’t notice when a signed document has been modified.
If you just paste a PNG or type your name — it’s wide open to manipulation.
This isn’t hypothetical. In 2023, a major insurance provider in Germany lost a court case because they couldn’t prove their PDF hadn’t been altered post-signing.
Cryptographic proof
A real digital signature creates a cryptographic hash — a unique fingerprint of the exact file version. If a single comma changes, the signature breaks.
That’s how digital signature verification works: visible, trackable, tamper-evident.
Platforms like DocuChain also record the signer’s IP address, timestamp, and a complete audit trail — making the document defensible in audits or legal disputes.
High-risk documents
- client contracts
- employment agreements
- NDAs
- copyright assignments
- financial reports
- These aren’t just documents — they’re liabilities. You need to sign sensitive documents in a way that proves not only who signed, but that nothing changed after.
Fast and secure
With DocuChain, you can create a digital signature online for free and sign documents online securely in under a minute. No installs. No logins. No setups. Each signed file includes embedded proof — not just a visual.
Trusted by design
Some tools don’t lock files after signing or skip metadata entirely. DocuChain doesn’t. It tracks everything. Once you sign, you know it’ll hold up — with clients, partners, or lawyers.
Trust starts at the signature.
When the document matters, don’t cut corners. Sign documents with DocuChain — with full encryption, verification, and audit history.
