OV-chipcard Security  Jeltje de Nieuwenhoven wrote a report during her function as OV (public transport) ambassador called "The OV-chipcard, the Traveler and Confidence" which concluded that "many travelers are not very concerned about privacy; it's only an issue when the media makes an issue of it. However a small amount privacy is important." De Winter found that these statements, other statements, and recommendations in this report were not substantiated, and so sent a WOB request in order to gain an understanding of the data on which these claims are based. De Nieuwenhoven rejected this application; De Winter presented this to court. The OV-chipcard/MIFARE uses 48-bit encryption and offers no modern security features. Netherlands in Open Connection  During the program's Open Standards and Open Source Software, later as part of the Open Source Software Strategy (for the government), (OSOSS) (2002–2007) and its successor Netherlands in Open Connection (NOiV) (2008–2011), de Winter followed developments critically. It turned out that the House of Representatives did not follow its policy on the implementation by the IT departments of the government. De Winter issued a WOB request to the Dutch Association of Municipalities (VNG) to gain more insight into the performance. When the VNG refused to make the information public, de Winter filed a lawsuit, and later, WOB requests to all individual municipalities, provinces, and many independent administrative bodies. Winter was on 16 December 2009 at the presentation of the Book A wall of rubber in the WOB in journalistic practice for to criticism from the parliamentarian Pierre Heijnen (PvdA). This was criticised by the other attendees at the meeting, including former minister Bram Peper. Criminal proceedings and dismissal  In 2011 de Winter was the subject of a criminal investigation. For uncovering weaknesses in the chip card and the central system, the Public Prosecutor assumed he was illegally cracking the cards. The company behind the chip card has reported. Winter by the Public Prosecutor considered suspicious for manipulating value cards, possession of means to do so, and computer intrusion. He faced imprisonment for up to six years. De Winter indicates that the manipulation was performed as part of the journalistic investigation into the weaknesses of the OV-chipcard expose and denounced the investigation. In demonstrating the weaknesses were also journalists, among others, the NIS, the public broadcasting Powned, Computerworld, RTV Rijnmond was involved.
