The duo sold Whisper Systems to Twitter (now X) in 2011, but Marlinspike continued to build on their existing work. In 2013 he founded the open-source nonprofit Open Whisper Systems, which in 2014 released the initial version of Signal, which supported only phone calls. The following year, Signal added texting to the app. In 2018 Brian Acton, who had cofounded the messaging app WhatsApp but had left the company in 2017, provided $50 million to create the nonprofit Signal Foundation with Marlinspike. Signal Messenger LLC operates as the foundation’s subsidiary and was created at the same time. When Marlinspike stepped down as CEO of Signal Messenger in 2022, Acton was named interim CEO. In June 2023 Signal announced on X that Acton would stay on as Signal Messenger’s CEO.

The Colorado Springs Police Department is proud of this new and innovative program, allowing for greater response efficiency and a safer community. To learn more about the Together COS program, please visit https://coloradosprings.gov/together-cos.

Signal was created by cryptographer and entrepreneur Moxie Marlinspike (a pseudonym for Matthew Rosenfeld), who also served as the company’s CEO from 2015 to 2022. In 2010 Marlinspike and roboticist Stuart Anderson, founded the security start-up Whisper Systems, which released the private text and call services TextSecure and RedPhone.

To make the Real-Time Crime Center operational, CSPD utilizes a technology platform called Fusus. Fusus is a map-based integration tool that combines private and public video streams, camera locations, law enforcement data, floor plans, live positions of first responders, live drone footage, and more. All of this information is then provided to the RTCC personnel and distributed to the responding officer or detective as needed, enabling for greater situational awareness and a common operating picture. What used to take hours or even days to do, now can happen in a matter of minutes.

The final portion of the RTCC is the drones as first responders program. This new program allows for a drone to be dispatched to certain types of calls in order to gain more information for possible responding officers. The information gathered by the drone will help dispatchers in the public safety communication center know the size of emergency response that is needed and communicate that information to responding officers. Dispatchers can also relay any information that may be available about victim or suspect locations, or even cancel a call before an officer arrives if an emergency is not taking place. By utilizing drones to gather more information, patrol resources can be dispatched more efficiently to the most emergent of calls within our community, lowering response times and increasing safety.

Through the camera registration option, community members can sign up with Fusus to let CSPD know they have personal security cameras at their home or business. By informing CSPD that you have cameras, it is easier for officers to conduct follow-up investigations in a neighborhood where a crime occurred by contacting those who have cameras. An officer or detective can email everyone in the vicinity of the crime asking those to search their video for suspicious activity. Users can then upload the video directly to the link provided by the detective. Providing video is completely voluntary and registering your camera does not give CSPD open access to your cameras or video.

Signal, private messaging app operated by the nonprofit organization Signal Foundation, based in San Francisco. Signal users can exchange text and voice messages, hold voice and video calls, send photos and videos, and communicate in group chats. The service can be accessed via a smartphone or desktop app.

While the RTCC is a CSPD-run program, there is a community involvement piece called Together COS. Together COS has two parts – camera registration and camera integration. Each part allows individuals and businesses across our community to share information with CSPD in various ways, to aid in making our community as safe as possible.

Signal’s disruption of traditional technological surveillance methods can prove frustrating for government and law enforcement officials. When requested, WhatsApp and most email providers may supply user data to law enforcement. Signal is unable to provide any user information other than when the app was downloaded and when it was last used. Such features differentiate Signal from fellow WhatsApp competitor Telegram, in which only chats specifically marked “secret” are protected by end-to-end encryption. Signal cannot view or audit any messages, and it has escaped some of the scrutiny faced by Telegram, which critics say facilitates communication among neo-Nazis and other extremists. Signal enables communication between users and their contacts, whereas Telegram allows users to join groups of like-minded strangers. Telegram’s platform advertises such groups and lets users search for them with hashtags.

Signal is a competitor of Acton’s former project, WhatsApp, which Facebook acquired in 2014. WhatsApp faced criticism for sharing user data with Facebook, which Facebook would then use to create targeted ads. Though WhatsApp now uses end-to-end encryption, its practices continue to be scrutinized by privacy advocates. On Signal, every conversation is protected by end-to-end encryption, with data being viewable only to chat participants.

One prominent Signal user is intelligence contractor and whistleblower Edward Snowden, who in 2013 leaked information regarding the surveillance of private American citizens by the National Security Agency (NSA). A personal friend of Marlinspike, Snowden once posted on X that he “use[s] Signal every day.” Signal is also used by social justice organizers in the United States and Hong Kong, as well as by journalists, intelligence professionals, and government officials, including members of U.S. Pres. Donald Trump’s administration. This has also led to scrutiny, as government officials are required by law to keep records of their communications.

Signal’s “disappearing messages” feature allows users to set a time period for how long their messages remain visible before they are deleted from the chat. The feature affects all participants in a chat, unlike deleting a message, which affects only one party. Signal requires users to enter a phone number to use the app and can alert users when numbers from their phone’s contacts join Signal. Both features have caused privacy concerns among some users.

Camera integration is the second option and is designed primarily for businesses in the community. Through camera integration, a business can purchase a Fusus core that will integrate security cameras with CSPD. If a serious crime occurs, detectives will have instant access to review the video camera recordings. They will be able to download the video to use in their investigation. During some of the most serious crimes, like an active shooter situation, the police department will be able to live stream the cameras to help identify and locate any potential suspects.

The Colorado Springs Police Department is proud to announce the launch of a new Real-Time Crime Center! The Real-Time Crime Center is a specialized CSPD unit, staffed by an analyst and detectives, which supports officers and detectives responding to calls for service and other investigations by providing them with real-time information. This information comes from department records, law enforcement databases, and other integrated technologies. This increased access to immediate information increases officer safety, community member safety, and investigative efficiency.
