Electronic signature
In addition to stipulating the legal definition and validity of electronic signatures, which prevent the impersonation of the creator of electronic documents such as contracts and the falsification of content, we have established a certification system for certification operations that confirm the validity of electronic signatures and meet certain standards.
Overview
Based on the " Act on Electronic Signatures and Certification Business (Act No. 102 of 2000) " (Electronic Signatures in Global and National Commerce Act), which came into effect on April 1, 2001, electronic documents, etc. with electronic signatures that meet certain requirements by the person concerned are presumed to be authentically established (prepared based on the intention of the person concerned). In addition, among the certification operations, those that meet certain standards (specified certification operations) can be certified by the national government.
