Updated Zero-Knowledge Authentication on our Mobile Apps
Our mobile apps have been updated with the latest encryption techniques in order to guarantee compliance the latest requirements.
Unlike pure zero-knowledge proofs implemented in software crypto-libraries, our solution is the only practical way to provide zero-knowledge authentication on smartphones given the lack of memory available on smartphones, and the wide variety of encryption schemes available on electronic identity cards and biometric passports.

Depending on the geographic area, pure software-based zero-knowledge solutions are leaving out 50-75% of potential users (i.e., those holding a smartphone and a biometric identity card/passport):
- In poorer countries, the hardware of most smartphones isn’t powerful enough
- Richer countries usually have a higher percentage of identity documents using elliptic curve cryptography (ECC)
- This situation is further aggravated with the trend to replace RSA with Elliptic Curve Cryptography (ECC) in both richer and poorer countries
