Space of Flex/AIR technologies

At the beginning of April (09.04.2009) Polish Ministry of Finance released their first Adobe AIR based application e-Deklaracje Desktop. This application lets its users submit annual tax declarations electronically and monitor their status. In Polish tax legislation every citizen is obliged to settle his income for previous year with tax office by the end of April. Historically e-Deklaracje project was initiated by Ministry of Finance in 2007/2008 but with less success and wide range adoption due to electronic signature requirement. By that time it required special hardware readers for digital signatures that are not commonly adopted in Poland.

This year Ministry of Finance has prepared change in legislation that was later signed by President of Republic of Poland that allowed sending annual declarations without qualified digital signature. Still to ensure proper security level users had to provide their personal information like: first name, last name, date of birth, NIP – tax identification number, PESEL – personal identification number and declared income from previous year. In reality this set of information is more than it was required in traditional paper based declarations (that’s the case with income from last year). I guess all this information gives better identity verification than traditional way where anyone can send his declaration by post or bring it in person to tax office (where no one asks for any id).

After only three weeks of availability over 77000 citizens have sent their declarations electronically (UPDATE 18.05: latest information from MF website states that 89000 declarations were sent, I guess those that forgot to do it till the end of April are still submitting)!!! This is incredible result taking into consideration such a short time, I believe next year we can expect this number to multiply couple times when people will have it available since January.

I’m also proud to say that local Adobe team (Tadeusz Chełkowski, Tomasz Lichota, Bartek Soin and of course myself) supported this project from very beginning with our technical and RIA experties.

Why Adobe AIR?

Ministry of Finance had couple of major requirements that had to be met by that type of application:

1. Cross-platform support – solution had to work without any compromises on all major operating systems like: Windows, Mac OS X and Linux.
2. Usability – it had to be easy to install and natural to use for inexperienced users. With badge installer on MF website it just couldn’t be made easier.
3. Security – give the users confidence that application they are installing was really issued by Ministry of Finance.
4. Interoperability – integration with SOAP based backend services.
5. PDF forms support – already existing PDF forms developed in previous year could be reused with small adjustments supporting non-qualified signature.
6. Desktop integration – required desktop features:
   

• Reliable local storage for drafts and sent declarations offline persistence;
• PDF forms templates and documentation local caching;
• Notifications mechanism for asynchronous confirmations (declarations receiving and confirmations service works in asynchronous mode with response time up to 24 hours).

As you can see all of above make Adobe AIR perfect fit for that type of applications. In my opinion the most important features in case of any application issued by public sector institutions are: cross-platform support, usability and security.

We had some stories in Poland in the past of applications written only for Windows platform with closed protocol specifications that ended with Linux users taking legal actions against publishing institutions. Adobe AIR built-in cross-platform support resolves this issue, I actually observed very positive feedback especially on Linux forums after e-Deklaracje release. Some comments stated that this is first time Polish government institution has noticed that there are also other OS’s than Windows.

In terms of usability there are two important factors, first of all installation process to make it as smooth as possible, ideally with small footprint, dependent runtime, tools and libraries automatic detection and installation (badge installer was resolving most of these, except Adobe Reader installation). Another factor is availability of experienced UI designers and developers. This is Adobe’s strong field with great community of Flash and UI design experts.

From the security perspective for application that gathers and sends out user personal information is important to give users confidence that the application was distributed by trusted entity and any communication with backed services is done through secure encrypted channels. Application issuer verification is Adobe AIR built-in feature with signed install packages.
