ST Screentext
End-to-end encrypted studio communication

Confidential text on the studio display. Unreadable to the server.

Screentext encrypts text in the operator browser. Only an explicitly approved display receives the wrapped session key and can decrypt the content. Designed for banks, insurers, government organisations, newsrooms and AV partners.

Decrypts the text locally, only after approval by the operator.

For organisations where confidential information must not be unnecessarily readable.

The security boundary

The server never receives readable screen text.

Security is not an afterthought. The entire transfer is designed to keep readable content within approved endpoints.

01

Encrypted at the source

AES-256-GCM encrypts the content in the operator browser before it is sent to Screentext.

02

No independent server key

The server stores ciphertext and wrapped keys, but cannot independently decrypt the session content.

03

Access after verification

A display gains access only after the operator has verified the temporary code and recognisable display name.

04

Temporary and revocable

Sessions expire automatically. Closing a session deletes encrypted content and immediately revokes display access.

Support without a back door

Administrators cannot simply read along either.

Temporary support access is created only after an explicit request and final approval by the operator, for one session and a limited period. Every step is recorded.
