At CrisisNote, we believe in giving you ultimate control over how and when your sensitive information is accessed. Whether it's a one-time emergency share or a controlled multi-party reveal, our platform ensures your privacy, security, and intent are respected.
In this post, we're introducing the Multi-Share feature — a secure, coordinated, and deliberate way of sharing secrets that require multiple people to unlock. But before we dive into Multi-Share, let's understand the difference between our two sharing approaches.
🔐 One-Time Share (Simple Share)
This is the most straightforward way to share your notes. You set a time limit — for example, 10, 20, or even 60 days — and the recipient gets access through a secure link. After the time expires, the note is no longer accessible.
It's perfect for:
- Temporary access to sensitive documents
- Single-person retrieval scenarios
- Quick, secure information sharing
🧩 Multi-Share: Secure Sharing with Multiple Keys
The Multi-Share approach is designed for high-security scenarios where access should be granted only if multiple trusted parties collaborate. It uses a threshold cryptography model where a secret is broken into parts and can only be reconstructed when a specified number of parts are combined.
🛠 How It Works
1. Minimum 3 Participants
You start by entering at least three email addresses. These are the trusted people who will receive parts of the secret.
2. Secret Splitting
The document is encrypted and split across the participants. Only when the required number of participants (threshold) combine their parts can the original secret be accessed.
3. Appointing a Master
You select a Master, the coordinator who receives visibility of all recipients. This person helps ensure coordination when it's time to access the note.
4. Add a Message
Optionally, you can include a personal note or explanation about why you're sharing this document.
5. Set a Waiting Time
You can specify a delay — say 60 days — before the secret becomes accessible. During this time, you can log in and cancel the request, preventing access.
6. Activity Notifications
You'll receive an email if someone tries to open the shared note. You can then decide to allow or reject the request.
7. Silent Rejection
If you reject access, the recipients will not be notified. From their perspective, they'll just keep waiting — ensuring no unintended information leaks.
🧠 Why Multi-Share Matters
Multi-Share isn't just about encryption — it's about intent, consent, and coordination. Here are some real-world scenarios where it shines:
🆘 In Case of Emergency
Share sensitive instructions or credentials with family or colleagues that should only be accessed if something happens to you. Set a waiting time of 60 or 90 days — if you're still active, just reject the request.
🔑 Secure Backup for Important Passwords
If you tend to forget your CrisisNote password — and since there's no recovery option — store it securely via Multi-Share. Trusted friends or colleagues can retrieve it for you if needed.
📜 Posthumous Information Delivery
Prepare a note to be delivered only after your passing. It could be final instructions, digital assets, or personal messages, ensuring your wishes are followed only when appropriate.
🤝 Multi-Person Decision Access
Need a document to be accessed only when several people agree? Multi-Share enforces this kind of access control without any manual gatekeeping.
🔐 Powered by Strong Encryption
Everything in Multi-Share is built on public-private key encryption. Your data remains secure and is never readable by our platform — not even during the sharing process.
🌊 Wave-Based Sharing for Extra Security
Our underlying system ensures that access only happens when conditions are met — with zero leakage of information to unauthorized users. It's an ideal solution when trust must be distributed and access should only be granted as a collective decision.
Conclusion
CrisisNote's Multi-Share gives you a unique and powerful tool to plan, share, and protect critical information with confidence and control. Whether you're preparing for emergencies, managing secure backups, or enforcing group decision-making, Multi-Share ensures that your data stays both safe and intentional.
