This is a specification of personal privacy preferences, based on ""Privacy Needs and Preferences List"  Google doc.  It defines the names and values and blocks thereof of various aspects that a user may or may not want to keep private.  The assumption is that these name/value pairs will be created, transmitted, and stored as a JSON data structure, and gives examples of how to create an actual such data structure.

privacyPreferences

The container for all of the user's privacy preferences. In JSON:

    "privacyPreferences" : { ... }

An empty privacyPreferences data structure implies using the default settings for all of the user's privacy preferences.

privacyPreferences.thirdPartyTracking

Defines a set of Boolean preferences with respect to third parties tracking a user's behaviour. The default setting is to prohibit all tracking by third parties.

• doNotTrack:
  • value:  true or false, defaults to true
  • user prefers that third parties not track.
• alerts
  • value:  true or false
  • ???
• allowTemporarily:
  • value:  true or false
  • temporarily allow third party tracking until the user leaves the page (or the site?  If the latter, then the value could be "page" vs. "site").

Example:

    "privacyPreferences": {
        "thirdPartyTracking": {
            "doNotTrack": true,
            "alerts": true,
            "allowTemporarily": true // ?? issue:  overrules doNotTrack?
        }
     }

privacyPreferences.thirdPartyScripts

Defines preferences for restricting third party scripts on a web page. There is no default setting in this case, since the setting is relative to a page or site.  Since there can be numerous sites and pages that these settings apply to, the thirdPartyScripts preference is an array of restrictions one a per site or per page.  Each site or pages is defined by a URI.

• site or page:
  • value: URI of the site or the page
• allow:
  • one of "true", "false", or "temporarily". (issue:  "always", "never", "temporarily" ??)

Example:

    "privacyPreferences": {
        "thirdPartyScripts": [{
            "site": "www.somewhere.com",
            "allow": "temporarily"
         },{
            "page": "www.elsewhere.com/login",
            "allow": true
         },{
            "site": "www.nefarious.org",
            "allow": false
         }]
    }

privacyPreferences.locationTracking

JSON Schema (Old)

Based on "Privacy Needs and Preferences List" Google doc.

"privacyPreferences": {
    "control": {
        "thirdPartyTracking": {
            "block": true, // "on/off" ?
            "alert": true, // "on/off" ?
            "allowTempoararily": true; // overrules "block": false
        },
        "thirdPartyScripts": {
            "allowThisSiteTemporarily": true,
            "allowThisSite": "siteURL", // "allowThisSite" overrules "allowThisSiteTemporarily"
            "allowThisPageTemporarily": "siteURL",
            "allowThisPage": "pageURL", // "allowThisPage" overrules "allowThisSiteTemporarily"
        },
    },
