About a month ago, I was in München, presenting What's new in PDF 2.0 regarding digital signatures. The people attending my talk, had to fill out a form, giving me a score from one to five: 1=excellent, 2=good, 3=fair, 4=unsatisfactory, 5=inadequate.
This is my score:
After a long train ride, we arrived in Munich, and our sales guy immediately started building the booth:
Afterwards, there was a reception and a whisky-tasting opportunity:
We didn't drink much whisky though. We mostly drank water and a little bit of wine.
Last week, I did a dry-run presentation of my talk for W-JAX (Münich) and it took me 75 minutes to explain everything I wanted to explain about digital signatures in PDF. Now I've updated my slides:
Dag in, dag uit worden we geconfronteerd met documenten. Veel van die documenten hebben een juridische waarde. Ze leggen beslissingen vast, ze bevestigen overeenkomsten, ze beschrijven rechten en plichten. Daarom is het belangrijk dat deze documenten een zekere vorm van beveiliging krijgen.
Zo spreken we van:
- Integrity: het document moet beschermd worden tegen al dan niet moedwillige wijzigingen.
- Authenticity: we moeten zekerheid hebben over de oorsprong van het document.
- Non-repudiation: het auteurschap van een document mag niet ontkend kunnen worden.
Van alle document formaten op de markt, is PDF dank zij het mechanisme van de digitale handtekening het meest geschikt om deze voorwaarden (integrity, authenticity, non-repudiation) te garanderen.
We’ve been busy!
Michael, Paulo and I had about 125 conversations during 3 days.
I must admit, 7 out of 10 people already knew iText. But for the ones who did not know us, we gave a brief corporate presentation, a quick functionality overview, and a link to some of our demo’s.
For PDF viewing, we kindly invited them to see our friends next door, and vica versa for PDF creation and manipulation. Having a “PDF corner” was a good marketing decision.
We showed people the improvements we made in xmlworker, XFA, and the android version. Signatures were revised to support PAdES, the new ETSI standard in digital signatures.
We were addressed to help on specific projects. Paulo Soares, co-developer of iText, at our booth, gave (free) expert advice that saved people time and money. They were of course very grateful. Some also wanted to come over and shake Bruno Lowagie’s hand. We told them he was busy finishing his whitepaper on digital signatures, and that they’d hear from him soon enough.
