![]() ![]() Moreover, legally speaking important data types like medical data or special data (information about race, religion or sex) are sadly missing. I like the consolidation of distinguishing only five different types of data (compared to Mehldau's more unwieldly and less structured set of data types). data sharing practices: shared with affiliates (bound by the same privacy practices), contractors (bound by the same privacy practices), or third parties ( not bound by the same privacy practices).general data collection practices: ad customisation (user data used to customise advertising), third party tracking (third parties are allowed to track user behaviour), public display (information contributed by the user may be displayed publicly), user control (users can access and correct personal information), data retention (including an indication of the retention period).types of data collected: contact information (name, address, email address, phone number), computer data (IP address, browser type, OS information), interactive data (browsing behaviour, search history), financial data (account status, credit information, purchase history), or content (personal communications, stored documents or media).They distinguished the following three categories of privacy characteristics. The KnowPrivacy project published a set of icons in 2009, as part of their Policy Coding Methodology. The KnowPrivacy Policy Coding Methodology I particularly like the distinction Mehldau makes between different kind of data retention periods:Īpart from that, the list of characteristics is quite large and rather unstructured. Mehldau makes no distinction between how the data is handled, and with/by whom: both types of icons are in the same category. It is interesting to note that Mehldau considers IP addresses to be in the same characteristic as files and time information, and that he considers things like conversations and favourites as separate characteristics that deserve a separate icon. for how long: for a session (end of usage/logout), until the end of a contract, for hours, for days, for weeks, for months, for years, for the time being (i.e. forever). ![]() for what purpose: statistics, advertisement, or shopping.how is it processed (and by whom): deleted, saved, anonymised, encrypted, published, passed on, for friends/contacts, for friends of friends, and whether you have a choice.what data is processed: real name, username, address, IP address/files/time, email address, comments/conversations, mails/messages, contacts/friends, favourites/interests, edits, and cookies.One early approach by Martin Mehldau from 2007, the Iconset for Data-Privacy Declarations, distinguished the following characteristics that each deserve a separate icon, grouped into four different categories: Martin Mehldau's Iconset for Data-Privacy Declarations I will briefly summarise and discuss each of these approaches below. the 'Policy Coding Methodology' of the KnownPrivacy project,.the 'Iconset for Data-Privacy Declarations' by Martin Mehldau,.Roughly in chronological order these are: Overview of existing approachesīased on the success of the Creative Commons icons to quickly communicate the license under which content can be shared, several proposals to use icons to summarise a privacy policy have been made in the past. I will also discuss some important conditions to make it more likely that such a set of icons becomes succesful in practice. After that I will synthesise the findings and propose a minimum set of privacy characteristics I think should be represented by an appropriate icon set. Instead I will focus on the privacy characteristics: which possible elements of a privacy policy, which essential aspects of the processing of personal data, must be represented by an icon?įirst I will discuss some existing (mostly abandoned) approaches, and some earlier analysis of these approaches. This is much better left the experts: graphical designers and user interface designers. In what follows I will not really discuss the visual design of such privacy icons, and how they should be embedded into the user interface. In this blog post I will discuss and analyse the main proposals, and suggest some steps forward. These icons should, when properly designed and used, summarise the privacy policy and convey its essential privacy characteristics. To allow people to nevertheless learn how websites, apps or services treat their personal data, the use of privacy icons have been proposed. They are very long, and written in 'legalese' that very few people understand. ![]()
