In relation to the application of the new European regulation GDPR (General Data Protection Regulation - EU Regulation 2016/679), in force since May 25, 2018, the need for a rigorous tracking of digital identities becomes increasingly evident. The certification, through digital signature with legal validity, of the identity of the signer of a document is one of the tools whose application will have to be increasingly spread within public and private companies. For this reason Sinapto has chosen to become a partner of Aruba PEC S.p.A. and provide the remote digital signature service. Within the partnership Sinapto has achieved certification for operators O.D.R. (Registration Operator). The service can be integrated into all the software developed and supplied by Sinapto.
