Security Architecture

Built for Paranoid-Level Privacy

Every layer engineered to ensure your data stays yours. We can't see it. We don't store it. We can't hand it over.

AES-256 Encryption

Military-grade encryption protects all documents and messages from upload to download.

Zero-Knowledge

Our servers never see your files, passwords, or content. Even we cannot access what you upload.

Fully Anonymous

No accounts. No tracking. No data collection. No cookies. Your identity stays completely hidden.

Single-Use Access

Content auto-deletes after one access. No copies persist. No traces remain anywhere on our servers.

Process

How InfoBin Works

Three steps to secure, anonymous file sharing or encrypted messaging.

01
Purchase Access Codes

Like buying a stamp - you need a code to send. Each code is a one-time-use ticket for uploading files (up to 256MB) or sending an encrypted message. Starting at £1.99 for 5 codes. No account required.

02
Upload & Encrypt

Enter your code, upload files or compose a message. The system generates three items for you:

Share Link - Send to your recipient
Password - Required to unlock the content
Delete Link - Optional early removal
Copy all 3 items immediately. They are shown only once.
03
Share via Separate Channels

Send the link and password through different channels for maximum security:

Email: "Here's your download link: ..."
Text: "Password is: XYZ789DEF456"

Interception of one channel doesn't compromise the other. Both pieces are required.

Architecture

Why This System is Secure

Gated Uploads

No valid code = no upload. Prevents spam, abuse, and keeps servers clean for verified users.

Two-Factor Retrieval

Link + password = double lock. Intercepting one is useless without the other.

Burn After Reading

One access then permanent deletion. No copies, no cache, no traces remain.

Sender Control

Delete link lets you revoke access before the recipient opens it. Full control.

Upload or Send

Enter your code. Upload files (256MB) or type message. Get link + password automatically.

Share Securely

Email the link. Text the password separately. Recipient needs both to access.

Recipient Access

Click link. Enter password. Download or read once. Everything auto-deletes permanently.

Delete Anytime

Use your delete link to remove content early. You control your data completely.

Auto-Expiration

Set time limit (1-12 hours). If not accessed, auto-deletes when time runs out.

Access codes prevent unauthorized uploads, spam, and abuse. This controlled access model ensures our servers remain secure and available only for legitimate paying customers, maintaining the integrity and reliability of the service.

Single-use access means your content self-destructs after being accessed once. Unlike traditional cloud storage where files can be accessed repeatedly (creating multiple vulnerability points), InfoBin ensures your sensitive data exists for the shortest possible time, dramatically reducing exposure risk.

Zero knowledge means we cannot see, access, or decrypt your content under any circumstances. Your data is encrypted before it reaches our servers using keys we never possess. Even if compelled by legal orders or threatened by hackers, we cannot reveal what we cannot see. There are no backdoors, no master keys, no exceptions.
