Directive 1999/93/EC of the European Parliament and of the Council of 13 December 1999 on a Community framework for electronic signatures

Official Journal L 013 , 19/01/2000 P. 0012 - 0020

DIRECTIVE 1999/93/EC OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL

of 13 December 1999

on a Community framework for electronic signatures

THE EUROPEAN PARLIAMENT AND THE COUNCIL OF THE EUROPEAN UNION,

Having regard to the Treaty establishing the European Community, and in particular Articles 47(2), 55 and 95 thereof,

Having regard to the proposal from the Commission(1),

Having regard to the opinion of the Economic and Social Committee(2),

Having regard to the opinion of the Committee of the Regions(3),

Acting in accordance with the procedure laid down in Article 251 of the Treaty(4),

Whereas:

• (1) 

  On 16 April 1997 the Commission presented to the European Parliament, the Council, the Economic and Social Committee and the Committee of the Regions a Communication on a European Initiative in Electronic Commerce;

• (2) 

  On 8 October 1997 the Commission presented to the European Parliament, the Council, the Economic and Social Committee and the Committee of the Regions a Communication on ensuring security and trust in electronic communication - towards a European framework for digital signatures and encryption;

• (3) 

  On 1 December 1997 the Council invited the Commission to submit as soon as possible a proposal for a Directive of the European Parliament and of the Council on digital signatures;

• (4) 

  Electronic communication and commerce necessitate " electronic signatures" and related services allowing data authentication; divergent rules with respect to legal recognition of electronic signatures and the accreditation of certification-service providers in the Member States may create a significant barrier to the use of electronic communications and electronic commerce; on the other hand, a clear Community framework regarding the conditions applying to electronic signatures will strengthen confidence in, and general acceptance of, the new technologies; legislation in the Member States should not hinder the free movement of goods and services in the internal market;

• (5) 

  The interoperability of electronic-signature products should be promoted; in accordance with Article 14 of the Treaty, the internal market comprises an area without internal frontiers in which the free movement of goods is ensured; essential requirements specific to electronic-signature products must be met in order to ensure free movement within the internal market and to build trust in electronic signatures, without prejudice to Council Regulation (EC) No 3381/94 of 19 December 1994 setting up a Community regime for the control of exports of dual-use goods(5) and Council Decision 94/942/CFSP of 19 December 1994 on the joint action adopted by the Council concerning the control of exports of dual-use goods(6);

• (6) 

  This Directive does not harmonise the provision of services with respect to the confidentiality of information where they are covered by national provisions concerned with public policy or public security;

• (7) 

  The internal market ensures the free movement of persons, as a result of which citizens and residents of the European Union increasingly need to deal with authorities in Member States other than the one in which they reside; the availability of electronic communication could be of great service in this respect;

• (8) 

  Rapid technological development and the global character of the Internet necessitate an approach which is open to various technologies and services capable of authenticating data electronically;

• (9) 

  Electronic signatures will be used in a large variety of circumstances and applications, resulting in a wide range of new services and products related to or using electronic signatures; the definition of such products and services should not be limited to the issuance and management of certificates, but should also encompass any other service and product using, or ancillary to, electronic signatures, such as registration services, time-stamping services, directory services, computing services or consultancy services related to electronic signatures;

• (10) 

  The internal market enables certification-service-providers to develop their cross-border activities with a view to increasing their competitiveness, and thus to offer consumers and businesses new opportunities to exchange information and trade electronically in a secure way, regardless of frontiers; in order to stimulate the Community-wide provision of certification services over open networks, certification-service-providers should be free to provide their services without prior authorisation; prior authorisation means not only any permission whereby the certification-service-provider concerned has to obtain a decision by national authorities before being allowed to provide its certification services, but also any other measures having the same effect;

• (11) 

  Voluntary accreditation schemes aiming at an enhanced level of service-provision may offer certification-service-providers the appropriate framework for developing further their services towards the levels of trust, security and quality demanded by the evolving market; such schemes should encourage the development of best practice among certification-service-providers; certification-service-providers should be left free to adhere to and benefit from such accreditation schemes;

• (12) 

  Certification services can be offered either by a public entity or a legal or natural person, when it is established in accordance with the national law; whereas Member States should not prohibit certification-service-providers from operating outside voluntary accreditation schemes; it should be ensured that such accreditation schemes do not reduce competition for certification services;

• (13) 

  Member States may decide how they ensure the supervision of compliance with the provisions laid down in this Directive; this Directive does not preclude the establishment of private-sector-based supervision systems; this Directive does not oblige certification-service-providers to apply to be supervised under any applicable accreditation scheme;

• (14) 

  It is important to strike a balance between consumer and business needs;

• (15) 

  Annex III covers requirements for secure signature-creation devices to ensure the functionality of advanced electronic signatures; it does not cover the entire system environment in which such devices operate; the functioning of the internal market requires the Commission and the Member States to act swiftly to enable the bodies charged with the conformity assessment of secure signature devices with Annex III to be designated; in order to meet market needs conformity assessment must be timely and efficient;

• (16) 

  This Directive contributes to the use and legal recognition of electronic signatures within the Community; a regulatory framework is not needed for electronic signatures exclusively used within systems, which are based on voluntary agreements under private law between a specified number of participants; the freedom of parties to agree among themselves the terms and conditions under which they accept electronically signed data should be respected to the extent allowed by national law; the legal effectiveness of electronic signatures used in such systems and their admissibility as evidence in legal proceedings should be recognised;

• (17) 

  This Directive does not seek to harmonise national rules concerning contract law, particularly the formation and performance of contracts, or other formalities of a non-contractual nature concerning signatures; for this reason the provisions concerning the legal effect of electronic signatures should be without prejudice to requirements regarding form laid down in national law with regard to the conclusion of contracts or the rules determining where a contract is concluded;

• (18) 

  The storage and copying of signature-creation data could cause a threat to the legal validity of electronic signatures;

• (19) 

  Electronic signatures will be used in the public sector within national and Community administrations and in communications between such administrations and with citizens and economic operators, for example in the public procurement, taxation, social security, health and justice systems;

• (20) 

  Harmonised criteria relating to the legal effects of electronic signatures will preserve a coherent legal framework across the Community; national law lays down different requirements for the legal validity of hand-written signatures; whereas certificates can be used to confirm the identity of a person signing electronically; advanced electronic signatures based on qualified certificates aim at a higher level of security; advanced electronic signatures which are based on a qualified certificate and which are created by a secure-signature-creation device can be regarded as legally equivalent to hand-written signatures only if the requirements for hand-written signatures are fulfilled;

• (21) 

  In order to contribute to the general acceptance of electronic authentication methods it has to be ensured that electronic signatures can be used as evidence in legal proceedings in all Member States; the legal recognition of electronic signatures should be based upon objective criteria and not be linked to authorisation of the certification-service-provider involved; national law governs the legal spheres in which electronic documents and electronic signatures may be used; this Directive is without prejudice to the power of a national court to make a ruling regarding conformity with the requirements of this Directive and does not affect national rules regarding the unfettered judicial consideration of evidence;

• (22) 

  Certification-service-providers providing certification-services to the public are subject to national rules regarding liability;

• (23) 

  The development of international electronic commerce requires cross-border arrangements involving third countries; in order to ensure interoperability at a global level, agreements on multilateral rules with third countries on mutual recognition of certification services could be beneficial;

• (24) 

  In order to increase user confidence in electronic communication and electronic commerce, certification-service-providers must observe data protection legislation and individual privacy;

• (25) 

  Provisions on the use of pseudonyms in certificates should not prevent Member States from requiring identification of persons pursuant to Community or national law;

• (26) 

  The measures necessary for the implementation of this Directive are to be adopted in accordance with Council Decision 1999/468/EC of 28 June 1999 laying down the procedures for the exercise of implementing powers conferred on the Commission(7);

• (27) 

  Two years after its implementation the Commission will carry out a review of this Directive so as, inter alia, to ensure that the advance of technology or changes in the legal environment have not created barriers to achieving the aims stated in this Directive; it should examine the implications of associated technical areas and submit a report to the European Parliament and the Council on this subject;

• (28) 

  In accordance with the principles of subsidiarity and proportionality as set out in Article 5 of the Treaty, the objective of creating a harmonised legal framework for the provision of electronic signatures and related services cannot be sufficiently achieved by the Member States and can therefore be better achieved by the Community; this Directive does not go beyond what is necessary to achieve that objective,

(a) as regards the accuracy at the time of issuance of all information contained in the qualified certificate and as regards the fact that the certificate contains all the details prescribed for a qualified certificate;

(b) for assurance that at the time of the issuance of the certificate, the signatory identified in the qualified certificate held the signature-creation data corresponding to the signature-verification data given or identified in the certificate;

(c) for assurance that the signature-creation data and the signature-verification data can be used in a complementary manner in cases where the certification-service-provider generates them both;

unless the certification-service-provider proves that he has not acted negligently.

• 2. 

  As a minimum Member States shall ensure that a certification-service-provider who has issued a certificate as a qualified certificate to the public is liable for damage caused to any entity or legal or natural person who reasonably relies on the certificate for failure to register revocation of the certificate unless the certification-service-provider proves that he has not acted negligently.

• 3. 

  Member States shall ensure that a certification-service-provider may indicate in a qualified certificate limitations on the use of that certificate. provided that the limitations are recognisable to third parties. The certification-service-provider shall not be liable for damage arising from use of a qualified certificate which exceeds the limitations placed on it.

• 4. 

  Member States shall ensure that a certification-service-provider may indicate in the qualified certificate a limit on the value of transactions for which the certificate can be used, provided that the limit is recognisable to third parties.

The certification-service-provider shall not be liable for damage resulting from this maximum limit being exceeded.

• 5. 

  The provisions of paragraphs 1 to 4 shall be without prejudice to Council Directive 93/13/EEC of 5 April 1993 on unfair terms in consumer contracts(8).

Article 7

International aspects

• 1. 

  Member States shall ensure that certificates which are issued as qualified certificates to the public by a certification-service-provider established in a third country are recognised as legally equivalent to certificates issued by a certification-service-provider established within the Community if:

(a) the certification-service-provider fulfils the requirements laid down in this Directive and has been accredited under a voluntary accreditation scheme established in a Member State; or

(b) a certification-service-provider established within the Community which fulfils the requirements laid down in this Directive guarantees the certificate; or

(c) the certificate or the certification-service-provider is recognised under a bilateral or multilateral agreement between the Community and third countries or international organisations.

• 2. 

  In order to facilitate cross-border certification services with third countries and legal recognition of advanced electronic signatures originating in third countries, the Commission shall make proposals, where appropriate, to achieve the effective implementation of standards and international agreements applicable to certification services. In particular, and where necessary, it shall submit proposals to the Council for appropriate mandates for the negotiation of bilateral and multilateral agreements with third countries and international organisations. The Council shall decide by qualified majority.

• 3. 

  Whenever the Commission is informed of any difficulties encountered by Community undertakings with respect to market access in third countries, it may, if necessary, submit proposals to the Council for an appropriate mandate for the negotiation of comparable rights for Community undertakings in these third countries.

ANNEX II

Requirements for certification-service-providers issuing qualified certificates

Certification-service-providers must:

(a) demonstrate the reliability necessary for providing certification services;

(b) ensure the operation of a prompt and secure directory and a secure and immediate revocation service;

(c) ensure that the date and time when a certificate is issued or revoked can be determined precisely;

(d) verify, by appropriate means in accordance with national law, the identity and, if applicable, any specific attributes of the person to which a qualified certificate is issued;

(e) employ personnel who possess the expert knowledge, experience, and qualifications necessary for the services provided, in particular competence at managerial level, expertise in electronic signature techology and familiarity with proper security procedures; they must also apply administrative and management procedures which are adequate and correspond to recognised standards;

(f) use trustworthy systems and products which are protected against modification and ensure the technical and cryptographic security of the process supported by them;

(g) take measures against forgery of certificates, and, in cases where the certification-service-provider generates signature-creation data, guarantee confidentiality during the process of generating such data;

(h) maintain sufficient financial resources to operate in conformity with the requirements laid down in the Directive, in particular to bear the risk of liability for damages, for example, by obtaining appropriate insurance;
