In part one, Osborne Clarke provides a legal opinion on the legal validity of electronic signature in the European Union. Part two has been prepared by OneSpan, and summarizes best practices recommendations for legal compliance when implementing e-signatures. eIDAS & E-SIGNATURE: A LEGAL PERSPECTIVE FOLLOW US 2 PART 1 Introduction The 2014 Regulation on Electronic Identification and Trust Services for Electronic Transaction in the Internal Market1 (“eIDAS”) went into effect throughout the European Union (“EU”) on 1 July 2016, replacing the 1999 Directive on electronic signatures2 (“the Directive”). Although the Directive had not been the subject of any disputes in its 16-year history, neither had it been a success. Its objective, to enable the widespread use of electronic signatures to conduct business across borders within the EU, was not met. There Are Three Key Reasons for This: I. Most EU Member States’ laws do not specify any form of signature for commercial contracts other than guarantees or contracts assigning real property. II. Many people mistakenly believed that the Directive mandated the use of advanced electronic signatures supported by a qualified certificate3 in order for an electronic signature to be legally effective.

The integrity of the appear that they had transpired within the previous fiscal year auditing records themselves is critical. By simply storing all the when, in reality, they had not. Consider a school database interactions in a separate audit log does not guarantee the where a student who receives a “F” in one of his subjects, in integrity of the log. Data tampering can be done through unauthorized access and in some cases through authorized users. which he needs at least a “B”, could be highly tempted to try Results of such action can be unpleasant for business and their to dishonestly change his grade to a “B” in the database. This clients. Therefore, a demand for audit log security is needed would be an example of a student who would have to hack more than ever. This paper describes a mechanism based on into the system, unless of course the student somehow had cryptographic hash functions and trusted timestamping that access to the database containing the grade. prevents an outsider or inside intruder from silently corrupting The above discussed examples provide just a few of the the audit log. In addition it is shown that the proposed mechanism can be realized in database systems with little reasons why someone might want to tamper with a database.

  • Virtualpatent - Enabling the Traceability of Ideas Shared Online Using Decentralized Trusted Timestamping
    Bibliographic Details BibTeX, EndNote… Related Work Authors’ Details VirtualPatent - Enabling the Traceability of Ideas Shared Online using Decentralized Trusted Timestamping Corinna Breitinger Bela Gipp Department of Computer and Department of Computer and Information Science Information Science University of Konstanz University of Konstanz [email protected] [email protected] Abstract Online discussion and sharing platforms have enabled ideas to be disseminated more quickly than ever before. However, there are many good reasons why individuals hesitate to share their ideas online. In academia, for instance, researchers may not want their contribution to be made public until after it has been published to ensure that they are appropriately credited for their work. As a consequence, novel ideas or creative work tend to only be shared within a small circle of trusted peers instead of with wider audiences online. This status quo prevents other experts on a specific topic from contributing to the discussion. In this paper, we present a proof-of-concept implementation of an online discussion and sharing platform that addresses this problem. The web- based application, coined VirtualPatent, automatically timestamps each post a user shares by creating a distributed timestamp on the blockchain of the cryptocurrency Bitcoin – a method for trusted-timestamp creation that we published in a previous paper. Unlike platform-managed timestamps, timestamps stored on the blockchain are persistent and cannot be tampered with. The system thus enables the author of a posting made online to retrospectively prove the exact time that the specific contribution was first put forth in a tamperproof manner – similar to a published paper, but with the simplicity of writing a post on a social media website.

  • Eidas Regulation Questions & Answers
    eIDAS Regulation Questions & Answers on rules applicable to Trust Services as of 1 July 2016 The eIDAS Regulation (Regulation (EU) N°910/2014) on electronic identification and trust services for electronic transactions in the internal market (eIDAS Regulation) adopted by the co-legislators on 23 July 2014 is a milestone as it provides a predictable regulatory environment for electronic identification and trust services, including electronic signatures, seals, time stamps, registered delivery and website authentication. As of 1 July 2016, the provisions applicable to trust services apply directly in the 28 Member States. This means that trust services under eIDAS are no longer regulated by national laws. As a result, the qualified trust services are recognised independently of the Member State where the Qualified Trust Service Provider is established or where the specific qualified trust service is offered. What’s new? What changes with regard to the former eSignature Directive? What must be done at national level? How does it impact market operators? How does it benefit the users (citizens, businesses and public administrations)? What has the Commission done to facilitate the switchover? These questions and many others have been asked along the road since the adoption. We have compiled this Q&A document to help those of you who need to fully understand the new legal framework in order to implement it or reap the benefits of electronic transactions, as well as those of you who are curious about the Regulation’s various implications. I. What is new? How will the legal effect of electronic signature change under eIDAS (compared to the regime under the eSignature Directive) as from 1 July 2016? Since 1 July 2016, when the trust services’ provisions under the eIDAS Regulation entered into application, an electronic signature can only be used by a natural person to “sign”, i.e.

  • The Ultimate Guide to Digital Signatures Comprehensive Answers to the 20 Most Important Questions
    The Digital Signature Company The Ultimate Guide to Digital Signatures Comprehensive Answers to the 20 Most Important Questions DocuSign | 855 Folsom St. Suite 939, San Francisco, CA 94107 | Tel. (415) 839-8161 | www.docusign.com Introduction As organizations increasingly adopt paperless processes and automate their document workflows, the “wet ink” signature is rapidly becoming an anachronism in our digital world. Companies and government organizations around the world have invested huge sums in automating their business workflows, yet they still find themselves printing paper for the purpose of obtaining signature approvals. Projects can be held up for days and costs are accrued while documents are mailed between offices, partners, suppliers or customers in order to collect signatures. Professionals often share the concerns voiced by compliance officers over how to ensure the integrity and accountability of electronic documents and records, and by CIOs over how to best secure them. Meanwhile, COOs are concerned with avoiding project delays and CFOs are seeking ways to cut costs associated with paper handling. Digital signatures address each and every one of these concerns.

What are Digital Signatures? Digital signatures, which are often referred to as advanced or standard electronic signatures, take the concept of traditional paper-based signing and turn it into electronic “fingerprints”, or coded messages, which are unique to both the document and the signer and binds the two together. They are based on international standards that guarantee their secure implementation.
