Secure Journalist Tip Line
An encrypted anonymous tip submission form for journalists and newsrooms. Source protection under Swiss press freedom Art. 17 BV and Redaktionsgeheimnis. Zero-knowledge — no identity required.
About this template
This template provides news organisations, investigative journalism units and individual journalists with a secure, encrypted anonymous tip line. It allows sources to submit information about corruption, safety issues, environmental violations, and other matters of public interest without revealing their identity. All submissions are end-to-end encrypted — the newsroom holds the only decryption key.
What it collects
- Category of tip for editorial routing
- Description of the alleged wrongdoing or issue
- Background context and source of knowledge
- Geographic or organisational context
- Urgency and public interest assessment
- Optional identity fields (entirely voluntary)
- Optional file upload for supporting materials
Source protection under Swiss law
Journalist source protection in Switzerland is guaranteed by Art. 17 of the Federal Constitution (Bundesverfassung) and the Redaktionsgeheimnis (editorial secrecy) principle. Journalists may not be compelled to reveal sources that were provided in confidence. This form is zero-knowledge: submitting anonymously leaves no identity data. If a source chooses to provide contact details, those details are encrypted and accessible only to the designated journalist.

Why source protection matters in Swiss journalism
Sources who provide information to journalists on sensitive matters — corporate wrongdoing, government corruption, workplace safety violations — often face significant personal and professional risk. Retaliation, dismissal, civil liability and in some cases criminal prosecution are all possible consequences for individuals who speak out. The protection of journalistic sources is therefore not merely a professional courtesy but a prerequisite for the free flow of information in a democratic society.
Swiss constitutional law recognises this explicitly. Article 17 of the Bundesverfassung guarantees press freedom and includes implicit protection for journalistic sources. The Schweizerische Strafprozessordnung (StPO) provides journalists with a right to refuse testimony regarding sources. These protections are only meaningful if the technical infrastructure supporting tip submission is genuinely secure. An unencrypted web form, an email address or an unprotected cloud submission can be subpoenaed, hacked or inadvertently disclosed. End-to-end encryption closes this gap.
What makes a tip line trustworthy for sources
A source considering whether to submit a tip asks a different set of questions than the journalist receiving it. The source wants to know: Can my submission be traced to me? Does the journalist know my IP address? What happens to the data after I submit? A credible tip line must answer all three questions satisfactorily:
- End-to-end encryption — content is encrypted in the source's browser and can only be decrypted by the journalist
- Zero metadata retention — IP addresses and device fingerprints should not be logged
- Anonymous by default — no identity required to submit
- Explicit statement of what data is retained and for how long
- Verification mechanism — sources should be able to verify the form belongs to the genuine newsroom
Editorial handling of anonymous tips
An anonymous tip is the beginning of a reporting process, not its end. Responsible investigative journalism requires independent corroboration of claims made by anonymous sources before publication. Newsrooms should establish an internal protocol for tip handling: who receives decrypted submissions, how tips are logged internally, how sources are protected even within the editorial team, and under what circumstances legal counsel should be consulted.
Frequently asked questions
Can a source's submission be traced back to them even without identity fields?
Technical metadata such as IP address, device fingerprint and submission timing can in principle be used to identify a source even if no identity information is provided. Sources who are particularly at risk should submit via a privacy-preserving browser (such as Tor Browser) from a public network rather than their home or work internet connection. Advise high-risk sources accordingly in your form instructions.
What is the Redaktionsgeheimnis and how does it protect sources?
The Redaktionsgeheimnis is the Swiss principle of editorial secrecy — the obligation of journalists not to disclose the identity of confidential sources. It is enshrined in Art. 172 of the Swiss Code of Criminal Procedure (StPO) as a right of journalists to refuse testimony. Courts cannot compel a journalist to name a source who provided information in confidence. This protection applies from the moment of submission — not only after publication.
Are file uploads in this form protected?
Yes. File uploads submitted through Schweizerform are encrypted end-to-end using the same key as the rest of the form. Only the designated form owner can decrypt uploaded documents. Sources should nevertheless be aware that document metadata (author, revision history, printer tracking dots in PDFs) can sometimes identify the origin of a document independently of the transmission channel.
