Replicant is a free and open source operating system based on the Android mobile platform, which aims to replace all proprietary Android components with their free software counterparts. This also makes it a security focused operating system as it closes discovered Android backdoors.〔(【引用サイトリンク】url=https://www.fsf.org/blogs/community/replicant-developers-find-and-close-samsung-galaxy-backdoor )〕 It is available for several smartphones and tablet computers.〔(【引用サイトリンク】title=Overview )〕 The name ''Replicant'' is drawn from the fictional replicant androids in the ''Blade Runner'' movie. Replicant is sponsored and supported by the Free Software Foundation. == History == The Replicant project started in mid-2010 with an effort to consolidate various initiatives attempting to produce a fully free-as-in-freedom Android derivative for the HTC Dream. The original team consisted of Bradley M. Kuhn, Aaron Williamson, Graziano Sorbaioli and Denis ‘GNUtoo’ Carikli. The project quickly led to the writing of replacement code for the non-free parts that were required to make the HTC Dream functional. The first component to be replaced permitted audio to work without a proprietary library. Replicant originally provided its own FOSS application repository, which was later replaced by F-Droid.〔(【引用サイトリンク】title=Replicant: Making Android truly free )〕 The software that was in charge of handling the communication with the modem (which is called Radio Interface Layer – RIL) was then replaced by free code, thus making the telephony part usable. A library handling the GPS was then adapted from free code that was originally written for another phone and permitted the HTC Dream to have GPS working with Replicant.〔 Early versions of Replicant were based on the Android Open Source Project code, while versions 2.2 (April 2011) and later use CyanogenMod as their base, in order to make supporting more devices easier. As development continued, many members of the original Replicant team retired from the project, making Denis "GNUtoo" Carikli the only remaining member from the original team still actively working on the project. In April 2011, Paul Kocialkowski decided to get involved with the project and gradually became the main Replicant developer, after successfully porting it to the Nexus S and Galaxy S devices.〔 Replicant is sponsored and supported by the Free Software Foundation,〔 which also hosts Replicant's source code. 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「Replicant (operating system)」の詳細全文を読む スポンサード リンク
