Glossary

Zero Knowledge Proof:

A cryptographic demonstration of truth delivered without exposing any underlying data used to perform the evaluation. An example: I know Joe is safe to enter my store and meets my COVID screening criteria, even though I have not accessed his medical data.

Digital Credential:

Bindle takes lab results or certifications from issuers on the Bindle network and generates a digital file displaying those results on a user’s smartphone. This is called a Digital Credential.

Issuer:

A person or an institution (like a diagnostic lab or doctor’s office) on the Bindle network that provides a lab result or vaccine certification.

Holder:

An individual on the Bindle network who is able to present their own digital credentials.

Verifier:

A person or an institution (like a school, business or stadium) that screens Bindle users against a Policy set by their organization.

Open:

Available for any person or institution to participate.

Interoperable:

Bindle standardizes digital credentials in a way that is suitable for many uses and verifiers, such that a single test result or vaccine certificate can be used to enter multiple shared spaces.

Network:

The persistent relationship between Issuers, Holders and Verifiers. The network allows everyone to communicate with each other according to the Bindle protocol.

Bindle:

Our digital wallet that allows anyone to store all of their digital credentials in a convenient and secure way.

Endpoints:

Any network participant, such as an Issuer, Verifier or a Holder.

Open Source:

The practice of publishing the computer code of a system for public use and inspection.

Personal Data:

Information that distinguishes individuals from each other. In particular, any information that they consider confidential or choose to treat in confidence.

Smartphone:

A personal computing device that is connected to the internet over a wireless telecom service.

Encrypted:

The state of a data message or payload in which the information it contains is indecipherable to a casual observer. Encryption makes it suitable for transmission without fear of being read or stolen, unintentionally or otherwise. Generally, the information can only be recovered by a party in possession of the cryptographic keys to unlock it.

Biometric:

An encoded identifier for a specific individual based on some unique attribute of their biology, such as their fingerprint, retina, DNA, or facial structure. For our purposes, we use biometric security like the fingerprint readers or facial recognition features on a smartphone.

Certificates or “Certs”:

An immutable digital asset published by an authenticable Bindle issuer.

Immutable:

Unchanging over time, or simply unable to be changed or altered.

Self-Sovereign:

The philosophy in software development which asserts that a private individual should maintain exclusive ownership over their personal data.

Token:

Any unique, immutable and portable digital asset. It’s what Bindle creates from digital certifications for users to gain access from verifiers.

Verifier Policy:

A screening rule set by the owner or manager of a location (verifier) for anyone who wants access into a shared space or activity.
