Data minimization

Datakeeper applies data minimization to your customer's identity data. Your customer adds a passport, ID card or driver's license to Datakeeper. An identity document normally contains a lot of data, but Datakeeper ensures that only the first name, last name and date of birth are used. We call this data minimization. We can also apply a zero-knowledge proof to the date of birth.

💡 With Datakeeper you can perform an age check easily and safely.

Zero knowledge proof

Datakeeper uses zero-knowledge proofs to prove that a date of birth or other number satisfies a certain property, without disclosing the specific metric, such as a date of birth.

💡 Validated age data with a privacy-friendly and innovative technology.

Easily implement age verification via QR code

Datakeeper guides you or your employees optimally through the implementation process. This way you can decide for yourself which data you want to request in your customer's QR code and which data you want to omit.

💡 Simple implementation. That is what Datakeeper guarantees.
