# Sidaxis

Sidaxis is the human authorisation layer for AI agents. It answers one question that no
password, token or session can answer: did a live human authorise this machine to do this?
Two primitives do the work. oneface proves a real, living person is present, on their own
device, storing no image and no template. Mandates record what that person authorised a
machine to do — scope, ceiling and expiry — and the layer refuses anything outside it.
Every action leaves a receipt anyone can verify without an account. Sidaxis never moves
money, never holds funds and never settles: the customer's own system or its payment
provider executes, or stops. Sidaxis is a product of Sieve Technologies, Inc., a Delaware
corporation operating from Frisco, Texas, United States.

## The thesis in one sentence

Software can act now; it still cannot prove who asked — and that proof is the missing layer.

## Products

oneface — proof of a live human. Advanced biometrics processed on the person's own device;
nothing is stored in a database, no template and no image. Speech correlated with the pulse
read by the camera at the same instant proves a living person is present at that moment;
cloned audio cannot produce that coincidence. Voice is never used to say who the person is.
The first identification is paid; recognising that person again is free for life, at any
volume. https://www.sidaxis.com/oneface

Mandates — proof of what that human authorised a machine to do. Five fields: granted_by,
granted_to, scope, ceiling, until. Every action is checked against the mandate at the layer,
revocation is free and immediate, and each action anchors a receipt that any counterparty
can verify. https://www.sidaxis.com/mandates

## The eight mandate scopes

login — agentic sign-in, free and unlimited.
purchase — an agent buying a specific good or service within a ceiling.
payment — an agent moving money through the customer's own provider, never through Sidaxis.
task — an agent carrying out work that commits the person to something.
signature — an agent signing a document on the person's authorisation.
data_share — release of the person's data to a named counterparty.
id_proof — proof of identity or an attribute to a counterparty.
access — physical or logical entry granted to an agent acting for the person.

it.

receipt history for the parties to a transaction. Not indexed.

Priced per authorisation, never as a percentage of what an agent spends. Agentic login is
free and unlimited. Recognising a person again is free for life. A failed call is never
billed. Details: https://www.sidaxis.com/pricing
