Mozilla Location Service (MLS) is open, crowdsourced geolocation service based on publicly observable cell sites (and their cell IDs) and Wi-Fi access points. The service is provided by Mozilla since 2013. In November 2015 MLS had collected more than 17 million unique cell networks and 427 million unique WiFi networks.〔(MLS stats ), accessed November 2015〕 The mobile app ''Mozilla Stumbler'' for Android is available in the Google Play store〔https://play.google.com/store/apps/details?id=org.mozilla.mozstumbler Play store〕 and on F-Droid.〔https://f-droid.org/repository/browse/?fdid=org.mozilla.mozstumbler〕 Mozilla does not collect the SSID name (e.g. "Simpson-family-wifi") from WiFi networks, but collects the BSSID (which is often the MAC address of the WiFi device).〔 To allow opt-out, Mozilla's client applications do not collect information about WiFi access points whose SSID is hidden or ends with the string "_nomap" (e.g. "Simpson-family-wifi_nomap").〔(Mozilla Location Service Opt-Out ) location.services.mozilla.com〕 Mozilla publishes aggregated data set of cell locations (MLS Cell Network Export Data〔https://location.services.mozilla.com/downloads〕) under a public domain license (CC-0).〔https://wiki.mozilla.org/CloudServices/Location/FAQ ()〕 Unlike the cell database, the raw WiFi database is not made public because the underlying data contains personally identifiable information from both the users uploading data and from the owners of WiFi devices.〔 However, Mozilla shares this proprietary data with its corporate partner Combain AB.〔https://blog.mozilla.org/services/2015/03/06/combain-deal-helps-expand-mozilla-location-service/〕 == See also == * Wi-Fi positioning system 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Mozilla Location Service」の詳細全文を読む スポンサード リンク
