질문

기관이 묻는 질문.

What does the Financial Services Agency expect?

The Financial Services Agency has published a study group report that asks financial institutions to inventory their cryptography and plan the transition to post quantum cryptography, with priority systems migrated in the early 2030s.

Does Qstamp meet the Electronic Books Maintenance Act?

Qstamp provides time evidence and audit trails for electronically stored tax records. The taxpayer remains responsible for meeting the conditions of the Act.

Does any personal information leave our systems?

No. Only salted commitments are anchored, which supports the security control measures of the Act on the Protection of Personal Information.
