While most systems intend to deliver a paperless environment to each institution it is recurrent that document integrity and accountability is still relying on traditional methods such as producing physical documents for signing and archiving. While this method delivers a non-efficient work- flow and has an effective monetary cost, it is still the common method to provide a degree of integrity and accountability on the data contained in the databases of the information systems. The evaluation of a document signature is not a straight forward process, it requires the recipient to have a copy of the signers signature for comparison and training beyond the scope of any office employee training, this leads to a serious compromise on the trustability of each document integrity and makes the verification based entirely on the trust of information origin which is not enough to provide non-repudiation to the institutions. -

Multiple Electronic Signatures on Multiple Documents
Multiple electronic signatures on multiple documents Antonio Lioy and Gianluca Ramunno Politecnico di Torino Dip. di Automatica e Informatica Torino (Italy) Abstract. European, international and Internet standards are available to support electronic signatures. The most common signature formats are defined via the ASN.1 syntax with DER encoding, or the XML language. Furthermore PDF is a widespread document format with support for e-signatures. Application of signa- tures to e-documents must consider several aspects: long term signature validity, non-repudiation, qualified certificates, and many others. This paper focuses on the relationships among multiple documents and multiple signatures and analyses the support provided by current formats to this problem. Where lack of standardiza- tion or standard profiling is found, a proposal is made towards better application of e-signatures. 1 Introduction It's a common belief that the field of electronic signatures (in short e-signatures) is an already established one. While this is true for the basic technical and legal foundations, we believe that many aspects have still to be investigated and properly defined. In partic- ular, the flexibility and richness of signature and documents in the paper world are still unmatched, and this can cause unexpected problems in real-life applications. In this pa- per we focus on the problems related to multiple signatures on the same document (as in the case of countersignatures), signature of document parts or of multiple documents. The complex relationships between multiple signatures and documents are explored, with reference to the major formats, to identify problems and suggest solutions that can improve the practical applicability of electronic signatures. -

On Organisational Involvement and Collaboration in W3C Standards Through Editorship Jonas Gamalielsson* and Björn Lundell
Gamalielsson and Lundell Journal of Internet Services Journal of Internet Services and Applications (2017) 8:5 DOI 10.1186/s13174-017-0056-1 and Applications RESEARCH Open Access On organisational involvement and collaboration in W3C standards through editorship Jonas Gamalielsson* and Björn Lundell Abstract Over time, a number of open standards have been developed and implemented in software for addressing a number of challenges, such as lock-in, interoperability and longevity of software systems and associated digital artefacts. An understanding of organisational involvement and collaboration in standardisation is important for informing any future policy and organisational decisions concerning involvement in standardisation. The overarching goal of the study is to establish how organisations contribute to open standards development through editorship. Specifically, the focus is on open standards development in the World Wide Web Consortium (W3C). Through an analysis of editorship for all W3C recommendations we contribute novel findings concerning organisational involvement and collaboration, and highlight contributions from different types of organisations and countries. We make five principal contributions. First, we establish an overall characterisation of organisational involvement in W3C standardisation. Second, we report on organisational involvement in W3C standardisation over time. Third, we establish how different organisations, organisation types, and countries are involved in W3C technologies. Fourth, we report on organisational -
