Dvina automatically detects and encrypts sensitive information the moment you type or upload content, ensuring your personal details never reach AI models in their raw form.
Using AI platforms shouldn't require you to constantly think about what information is safe to share. Yet most people find themselves in an exhausting mental checklist: Does this document contain my email? Are there phone numbers in this contract? Should I redact names before uploading?
This friction slows you down and creates anxiety. You either spend time manually reviewing and removing sensitive details, or you take the risk and share everything, hoping the platform handles it responsibly.
Dvina eliminates this dilemma entirely.
The Problem: Personal Data Hiding in Plain Sight
Consider everyday scenarios where sensitive information appears without you actively thinking about it:
Uploading a signed contract
Your name, signature, email address, and phone number are embedded in the document. You might remember to check the first page, but what about contact details buried in the footer or annexes?
Sharing meeting notes
Team members' emails, phone numbers, and sometimes even home addresses appear in calendar invites or notes you paste into a prompt.
Analyzing financial documents
Bank account numbers, credit card details, transaction IDs: these often slip into spreadsheets or PDFs you want AI to summarize.
Drafting personal correspondence
You're asking AI to help write an email to your doctor, lawyer, or accountant. The draft naturally includes their contact information and yours.
Most AI platforms process all of this data exactly as you provide it. The information gets logged, stored, and in many cases, used to train future models. Even if a platform claims not to train on your data, the raw information still passes through their systems and sits in their databases.
How Dvina's Automatic Data Masking Works
Dvina approaches this problem from a fundamentally different angle: protect everything by default, automatically.
The moment you type a message or upload a file, Dvina's detection system scans the content in real time. It identifies:
- Personal identifiers: Names, email addresses, phone numbers, physical addresses
- Financial information: Credit card numbers, bank account details, transaction IDs
- Government IDs: Social security numbers, passport numbers, tax IDs
- Health information: Medical record numbers, insurance details
- Authentication data: API keys, passwords, tokens
Once detected, sensitive data is immediately encrypted and replaced with anonymized placeholders before being sent to any AI model.
Here's what that looks like in practice:
Original text you type:
"Please draft an email to John Smith at john.smith@company.com regarding invoice #4532-8821 paid via card ending in 4242."
What the AI model actually sees:
"Please draft an email to [PERSON_1] at [EMAIL_1] regarding invoice [ID_1] paid via card ending in [CARD_1]."
The AI can still understand the context and generate a helpful response. But your actual personal details never leave your device in plain text. They're encrypted locally and only the placeholders are processed.
When Dvina returns the AI's response to you, it automatically reverses the process, replacing placeholders with the original information so the output makes sense.
Why This Matters More Than You Think
You don't have to remember what's sensitive
Dvina knows. You can upload contracts, paste emails, share documents without worrying. The system catches details you might overlook.
No manual redaction required
Stop spending time blacking out text or retyping documents with fake data. Work naturally and let Dvina handle the protection.
Protection extends to uploaded files
PDFs, Word documents, spreadsheets: Dvina scans all file types for sensitive information before processing. Even data buried deep in a 50-page report gets detected and masked.
Works in real time, invisibly
The masking happens instantly. You never see a loading screen or need to approve each detection. It's seamless.
Real-World Use Cases
A parent planning a family trip
Sarah is using AI to help organize a vacation. She pastes her family's passport numbers, hotel confirmation with credit card details, and flight bookings with everyone's dates of birth. Dvina automatically masks all personal identifiers. The AI helps create an itinerary and packing list, but her family's sensitive travel documents never appear in the system's logs.
Someone filling out an insurance claim
After a minor car accident, Mike asks AI to help him complete his insurance claim form. He uploads photos of his driver's license, vehicle registration, and the other driver's contact information. Dvina masks all ID numbers, addresses, and phone numbers while the AI guides him through the form fields and suggests what documentation he still needs.
A student applying to universities
Emma is drafting her college application essays and asks AI for feedback. Her documents contain her social security number, home address, parents' financial information, and test scores. Dvina encrypts all personal details so the AI can critique her writing style and suggest improvements without ever seeing her actual identifying information.
A freelancer managing client invoices
James uploads a batch of invoices to ask AI to categorize expenses for his taxes. The documents contain client names, business addresses, payment details, and bank transfer information. Dvina masks everything sensitive, allowing the AI to organize the data by category and calculate totals without accessing real financial details.
Someone seeking medical advice research
Lisa wants to understand her recent diagnosis better. She copies her lab results, prescription details, and doctor's notes to ask AI for simplified explanations. Dvina automatically encrypts her medical record number, prescription IDs, and doctor's contact information while still letting the AI explain the medical terminology in plain language.
Legal professionals reviewing contracts
A lawyer uploads a client agreement filled with personal details, financial terms, and confidential clauses. Dvina masks all identifiable information, allowing the AI to analyze legal language and structure without ever seeing real names, addresses, or sensitive terms.
Healthcare administrators processing patient data
A clinic manager asks AI to summarize intake forms. Patient names, insurance numbers, and contact details are automatically encrypted. The AI can still generate the summary, but protected health information never appears in logs.
Finance teams analyzing transactions
An accountant uploads a bank statement with dozens of transactions. Account numbers, cardholder names, and amounts are masked before the AI processes the data. The AI can identify spending patterns and categorize expenses without accessing actual financial details.
HR departments handling employee records
An HR manager needs help drafting a policy update based on employee feedback forms. Names, emails, and departmental information are automatically anonymized. The AI analyzes sentiment and themes without linking feedback to specific individuals.
Technical Implementation
Dvina's masking system operates on multiple layers:
Server-side detection
When data reaches Dvina's secure servers, it immediately passes through advanced PII detection engines before it ever reaches any AI model.
Pattern recognition algorithms
The system uses advanced pattern matching to identify dozens of data types across multiple formats and languages.
Encryption before transmission
Detected data is encrypted using industry-standard protocols. Only encrypted placeholders travel to Dvina's servers.
Contextual preservation
Placeholders maintain context so the AI model can still understand relationships and generate accurate responses.
Automatic reversal
When results return to you, placeholders are replaced with original data. The decryption happens locally, ensuring end-to-end protection.
Beyond Compliance: True Privacy by Design
Many platforms offer redaction tools or warn you not to share sensitive information. But this puts the burden on you to identify and protect your own data.
Dvina reverses that model. Privacy is automatic, invisible, and comprehensive. You get the full power of AI without sacrificing control over your information.
Whether you're working with contracts, financial records, personal correspondence, or confidential business documents, Dvina ensures that your sensitive data stays encrypted from the moment it enters the system until the moment it returns to you.
Your information. Your control. Automatically protected.
