Document Structure

I _ Customer’s signature: – Client’s encrypted biometric data– Client’s encrypted biometric data is embeded to the document– Integrity of the document is ensured by digital signature certificate ( I certificate)– Cryptographic Time-Stamp is used for first digital signature

II _ Bank’s signature _ Signatory – physical entity: – Client’s encrypted biometric data– Client’s encrypted biometric data is embeded to the document– Integrity of the document is ensured by digital signature certificate ( I certificate)– Cryptographic Time-Stamp is used for second digital signature

I _ customer’s signature _ Signatory – legal entity: – CA issues Signature digital certificate to the Bank– Integrity of the document (with customer’s signature) is ensured by digital

signature ( I certificate)– Cryptographic Time-Stamp is used for second digital signature

III _ Electronic Stamp: – CA issues Signature digital certificate to the Bank _ Stamp certificate (II certificate)– Client’s encrypted biometric data is embeded to the document– Integrity of the document is ensured by digital signature certificate – Cryptographic/Local Time-Stamp is used for Electronic Stamp

Long term validation

Long term validation means:• certificate validity evaluating at the moment of signing; • biometric data availability and validity for expertise purposes

Document format _ PDF A/ - 2a

Electronic Document Retime-stamping: • Using of Document Time-Stamp, IN CaSE:• Trusted TS private key is expiring• Technical parameters lose the recommended status• Case of compromise is identified• Document integrity becomes challengeable
