Catherine Andersz of PDFTron Systems, Alaine Behler of iText Software and Peter Wyatt, ISO Project Leader for ISO 32000 enrich the newly elected board of the PDF Association.
Joris Schellekens, Software Engineer at iText Software, will be hosting a presentation titled“Blockchain and Distributed Ledger Technology for Documents” at the PDF Days Europe 2018.
Presenter: Joris is a 29-year old software developer at iText, a global IT firm with a leadership position in pdf creation. Joris’ background is in machine learning, NLP, mathematics, graphs and NP-complete problems. After having worked in the supply-chain industry, he set his sights on document-processing and workflow-automation. At iText he focusses mostly on innovative research projects.
Session Description: Blockchain is a type of DLT in which records are organized in blocks that are appended to a single chain using cryptography and distributed consensus. Each block contains a time stamp and a link to the previous block, ensuring that data in a block can’t be altered retroactively. This makes blockchain a good choice for the recording of events, provenance tracking, and document life-cycle management. Signing a PDF in the blockchain instead of storing a signature in a PDF reduces the complexity of the code for a developer who needs digital signing and verification functionality. The same principle can be used in many other use cases to implement a document workflow, to keep track of the location of a document, and much more.
