Records
Every outgoing message gets a number, a timestamp and a seal. The log records what went out and when.
Focus · MLKI and Eigenkern Pseudomizer
Use cloud AI. Keep the originals.
The local AI MLKI stays in your house. The Pseudomizer creates a shadow copy of your documents in which names and confidential details are replaced. Only after a check chain may this copy go to a large cloud AI. The leak rate at the exit is 0.00 %: guards detect, the judge stage blocks when in doubt, healing cleans up.

The leak rate
0.00 % at the exit. We disclose the test series.
The leak rate is the share of sensitive details (names, companies, identifiers) that still appear in full in the shadow copy after pseudonymisation. At the exit it is 0.00 %, because guards, judge stage and healing work together.

The figures are technical measurements with test data, not a legal certificate and not a promise for your documents. We measure which rate is reached with your documents in the test with you.
A shadow goes out, not the original
The shadow copy carries the meaning of your document, but not your names and identifiers.
Briefly explained
How does a name stay secret?
Names are replaced by placeholders, the key stays with you.

The data recorder
It records what goes out.
Like the flight recorder in an aircraft: every message to a cloud AI is stored numbered and sealed. You can look up what went out, and prove it.

Every entry carries the seal of its predecessor. If one is changed or deleted, the chain breaks from that point.
Example with invented values
Sealed
The entries are linked as a seal chain. Anyone who changes or deletes an entry afterwards breaks the chain, and it shows.
Does not check, only records
Checking is done by the check chain before it. The data recorder sits at the exit, sees the real data and cannot be lied to by the services behind it.
Status: connected in our test environment; connection to all routes to cloud AI services is in progress. The log shows what went out. It does not replace a legal certificate.
The check chain
Six steps before anything leaves the house.
Each step is a separate, independent check. If anything is found in a step, nothing goes out.
01
The original stays in the house.
Your documents are on the device in your business. MLKI reads and sorts them there.
02
Detect several times.
Several detection modules run in series and search for names, companies, addresses and identifiers. A second, independent detection catches what the first one misses.
03
Create the shadow copy.
Details found are replaced by related words so that the meaning of the document is preserved. Figures, amounts and quantities stay unchanged.
04
Check and judge.
An independent check chain searches every job once more for remnants, using dictionaries and rules per subject area. Then the judge, a separate AI stage, rules on every suspicious passage in the context of the sentence. If it is not sure, or the judges disagree, the passage is blocked. If anything is found, nothing is sent.
05
The cloud AI works on the shadow.
Only the checked shadow copy goes to the chosen cloud AI. It never sees the original.
06
Return path at your site.
The answer comes back. Only at your site are the real details put back in.
Checked before anything goes out
An independent check chain inspects every job. If anything is found, nothing goes out.
Security and documentsSubject-specific check chains
Every industry has its own details.
The check chain works per document type and subject area with its own dictionaries and rules. What is sensitive in a tax practice differs from what is sensitive in a medical practice or a biogas plant.
Tax and law
Clients, case numbers, bank details and addresses.
To the industryMedicine and practices
Names, addresses and details that fall under professional secrecy.
To the industryEnergy and biogas
Metering points, plant identifiers, contract partners and bank details.
To the industryIndustry and administration
Customer, supplier and project names as well as case numbers.
To the industryWe set up further subject areas together with industry partners. The dictionary of a subject area is built from real documents of that industry.
Stated openly
What you should know.
No 100 percent promise
No method recognises every detail. That is why we check twice and independently, block on every finding and measure with test data.
Technical evidence
Our measurements are technical evidence, not a legal certificate. We clarify legal bases and access rights with you before the start.
Status: alpha
The Pseudomizer is under development. German, English, French and Nordic languages are tested. Cyrillic and East Asian scripts need their own models and have not yet been tested.
The key stays with you
The return path with the real details runs at your site, not in the cloud.
