PrivatOS
PrivatOS was an operating system used in the Blackphone from June 1, 2014, to June 30, 2016. It was targeted at users who sought improved privacy and security. It provided encryption for phone calls, emails, texts, and internet browsing. PrivatOS was a modified version of Android, forked from Android 4.4.2, that came with a bundle of security-minded tools. However, in contrast to Android, PrivatOS was not open source. The company that shipped PrivatOS, SGP Technologies is a joint venture between the makers of GeeksPhone, and Silent Circle. Background The concept of an encrypted phone had long been an interest of Silent Circle founder and PGP creator, Phil Zimmerman. In a video on Blackphone's website, Zimmerman said, Features The company stated its operating system was able to “close all backdoors” which were usually found on major mobile operating systems. Some major features of PrivatOS were anonymous search, privacy-enabled bundled apps, smart disabling of Wi-Fi except ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Silent Circle is an encrypted communications firm based in Washington DC. Silent Circle provides multi-platform secure communication services for mobile devices and desktop. Launched October 16, 2012, the company operates under a subscription business model. The encryption part of the software used is free software/ open source and peer-reviewed. For the remaining parts of Silent Phone and Silent Text, the source code is available on GitHub, but under proprietary software licenses. History In November 2011, Mike Janke called Phil Zimmermann with an idea for a new kind of private, secure version of Skype. Zimmermann agreed to the project and called Jon Callas, co-founder of PGP Corporation and Vincent Moscaritolo. Janke brought in security expert Vic Hyder, and the founding team was established. The company was founded in the Caribbean island of Nevis, but moved its headquarters to Le Grand-Saconnex near Geneva, Switzerland in 2014 in search of a country with "stronger privacy l ...

Blackphone
The Blackphone is a smartphone built to ensure privacy, developed by SGP Technologies, a wholly owned subsidiary of Silent Circle. Originally, SGP Technologies was a joint venture between the makers of GeeksPhone and Silent Circle. Marketing is focused upon business users, stressing that employees often conduct business using private devices and services that are not secure and that the Blackphone service readily provides users with options that ensure confidentiality when needed. Blackphone provides Internet access through VPN. The device runs a modified version of Android called SilentOS that comes with a bundle of security-minded tools. Versions of the Blackphone were sold from 2014–2016. While precise sales figures were not released, it is widely speculated to have been a financial disappointment due to the resulting near-bankruptcy of Silent Circle combined with Silent Circle canceling the phone.

GeeksPhone
GeeksPhone was a Spanish smartphone company founded in 2009. GeeksPhone's most notable products are open Android phones and developer devices of Firefox OS. History GeeksPhone was founded in early 2009 by Javier Agüera and Rodrigo Silva-Ramos. Its first product, the GeeksPhone One, was announced in 2009 and started shipping in early 2010, becoming the first European brand to launch an Android smartphone to the mass market. It subsequently manufactured the Keon and Peak smartphone models, the first developer preview devices running Firefox OS. A consumer model, the Peak+ was announced later. It was thought to be a refinement of the Peak model, geared towards a non-developer audience, but problems concerning the availability of batteries from the Chinese ODM led to the discontinuation of the project without a single unit being marketed. In November 2013 the company announced a new model of smartphone called Revolution. It was thought to be a high-end model, but it was then rev ...

Phil Zimmerman
Philip R. Zimmermann (born 1954) is an American computer scientist and cryptographer. He is the creator of Pretty Good Privacy (PGP), the most widely used email encryption software in the world. He is also known for his work in VoIP encryption protocols, notably ZRTP and Zfone. Zimmermann is co-founder and Chief Scientist of the global encrypted communications firm Silent Circle. Background He was born in Camden, New Jersey. Zimmermann received a B.S. degree in computer science from Florida Atlantic University in Boca Raton, Florida in 1978. In the 1980s, Zimmermann worked in Boulder, Colorado as a software engineer on the Nuclear Weapons Freeze Campaign as a military policy analyst. PGP In 1991, he wrote the popular Pretty Good Privacy (PGP) program, and made it available (together with its source code) through public FTP for download, the first widely available program implementing public-key cryptography. Shortly thereafter, it became available overseas via the Internet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pretty Good Privacy
Pretty Good Privacy (PGP) is an encryption program that provides cryptographic privacy and authentication for data communication. PGP is used for signing, encrypting, and decrypting texts, e-mails, files, directories, and whole disk partitions and to increase the security of e-mail communications. Phil Zimmermann developed PGP in 1991. PGP and similar software follow the OpenPGP, an open standard of PGP encryption software, standard (RFC 4880) for encrypting and decrypting data. Design PGP encryption uses a serial combination of hashing, data compression, symmetric-key cryptography, and finally public-key cryptography; each step uses one of several supported algorithms. Each public key is bound to a username or an e-mail address. The first version of this system was generally known as a web of trust to contrast with the X.509 system, which uses a hierarchical approach based on certificate authority and which was added to PGP implementations later. Current versions of P ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fork (software Development)
In software engineering, a project fork happens when developers take a copy of source code from one software package and start independent development on it, creating a distinct and separate piece of software. The term often implies not merely a development branch, but also a split in the developer community; as such, it is a form of schism. Grounds for forking are varying user preferences and stagnated or discontinued development of the original software. Free and open-source software is that which, by definition, may be forked from the original development team without prior permission, and without violating copyright law. However, licensed forks of proprietary software (''e.g.'' Unix) also happen. Etymology The word "fork" has been used to mean "to divide in branches, go separate ways" as early as the 14th century. In the software environment, the word evokes the fork system call, which causes a running process to split itself into two (almost) identical copies that (ty ...

Android (operating System)
Android is a mobile operating system based on a modified version of the Linux kernel and other open-source software, designed primarily for touchscreen mobile devices such as smartphones and tablets. Android is developed by a consortium of developers known as the Open Handset Alliance and commercially sponsored by Google. It was unveiled in November 2007, with the first commercial Android device, the HTC Dream, being launched in September 2008. Most versions of Android are proprietary. The core components are taken from the Android Open Source Project (AOSP), which is free and open-source software (FOSS) primarily licensed under the Apache License. When Android is installed on devices, the ability to modify the otherwise free and open-source software is usually restricted, either by not providing the corresponding source code or by preventing reinstallation through technical measures, thus rendering the installed version proprietary. Most Android devices ship with additional ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
