The purpose of a Qualified Certificate (QC) is to enable the creation of Qualified Electronic Signature (QES) in accordance with the Electronic Documents and Signatures Law of Macao SAR (EDS Law no. 5/2005) and others international standards, using together with a Secure Signature-Creation Device (SSCD).
According to the Law, an Electronic Document signed with a Qualified Electronic Signature (QES) is equivalent to a hand-written signature with full evidentiary power in term of legal effectiveness.
Benefits of using QES
QES was specially designed to provide you with the following necessary assurances, required for legal and secure electronic transactions:
- Authentication (who you are);
- Integrity (what you sent);
- Non-repudiation (you can’t deny it);
- Confidentiality (accessible only to those authorized to have access).
Some of the key advantages of using the Qualified Certificate are:
- The highest assertion level available for verifying your personal electronic identity;
- Protection and assurance of extremely sensitive information and high value transactions;
- Detection of any fraudulent alteration of electronic documents and transactions;
- The verification of the lawful authenticity and validity of the QES;
- Creation of a non-reputable signature on electronic transactions or documents;
- Eliminate any probability of accepting forged documents.
Optional Encipherment Certificate can also be used together, the main purposes of utilising the Encipherment Certificate are:
- Protection of secret or confidential information from unintended audience;
- State-of-the-art technology used for encryption.
Taking into consideration the different needs and rights of individual users and corporations, eSignTrust issues three similar but distinctively suitable Qualified Certificates.
- Personal Qualified Certificate - is intended for a natural person with valid proof of identity. The usage of this Certificate is for signing documents on one's own behalf.
- Corporate Qualified Certificate - is designed for authorized personnel of a company, enterprise, institution or association etc, with a valid business registration certificate issued by Government of Macao SAR or a legal registered unit in Macao. The usage is intended for signing documents on behalf of his or her represented organisation.
- Government Qualified Certificate - will be used by authorized personnel of a government agency or department. The usage is intended for signing documents on behalf of his or her government agency or department.
Since a Qualified Certificate will validate the identity of its holder, hence all QES applicants must be satisfactorily identified before they receive a Qualified Certificate. The applicants are required to meet with a Registration Authority (RA) Officer or representative during the identification process. If the applicants are outside Macao, the Registration Authority will provide online Identification and Authentication service to those who are eligible.
The Qualified Certificate and Encipherment Certificate together with their respective Private Keys will be stored inside a Secure Signature-Creation Device (SSCD); therefore the holder of the certificates must supply a personal password during the registration to protect and access those keys.
