The Guardian Launches CoverDrop for Secure Whistleblower Communication

The Guardian has unveiled CoverDrop, a secure messaging service designed to protect whistleblowers and confidential sources. This new feature, set to integrate with the existing mobile app, will allow for encrypted communication and file transfers via SecureDrop.

CoverDrop, developed by The Guardian's software engineers, employs a novel method based on a University of Cambridge research paper. It uses encrypted text hidden within data packets to safeguard the identity of sources and their messages. The system relies on 'security by multiplicity', making it nearly impossible to pinpoint the origin of communications.

The service uses an un-trusted API service and on-premise software at The Guardian's headquarters to manage messages. Once integrated with SecureDrop, CoverDrop will enable journalistic sources to share files directly with Guardian staffers, further bolstering the organisation's commitment to secure and anonymous communication.

CoverDrop, an open-source software, is a testament to The Guardian's dedication to protecting whistleblowers and confidential sources. By integrating it with SecureDrop, the organisation ensures secure file transfers, adding another layer of protection for those who wish to expose wrongdoings anonymously.
