About

Swift Digital ID

Read full description

Swift Digital Identity is a smartphone based electronic identity application to create digital signatures without requiring any special or additional hardware on the client device. It makes use of SMPC software of back end and client components and is integrated with a Swift CA that issues certificates. Digital signatures enable authentication and signing on remote systems like banking websites. Β  The solution is based on SMPC-based cryptographic algorithms, which allow a user’s private key to be split between the user’s smartphone application and back end server in such a way that the server is not able to issue signatures under the name of the user.
