Verification of the OSF electronic seal

PDF documents generated by the OSF system have an electronic seal of the National Information Processing Institute (OPI PIB) attached to them. This seal is used to ensure the integrity of data included as part of the generated document (it is possible to verify whether the data wasn’t modified, added or deleted in an unauthorized manner). The presence of the National Information Processing Institute electronic seal confirms the OSF system as the source of this data. The document with this seal can be signed by the User with his own digital signature.

The certificate linked with the seal of our system was issued by CERTUM General Certification Centre which provides services related to electronic signatures and is a certification authority (CA).
