Understanding Instnt's Platform

The following pages describe in detail the integration requirements and back end functionality of Instnt's platform. 

Data Encryption and Decryption

Learn how to encrypt your public/private keypairing and decrypt the assertion response payload in order to fully onboard with Instnt!

You alone, being in possession of the private portion of the keypair, can decrypt this data. These keys are signed via RSASSA-PKCS1-v1_5 SHA256 and encrypted by RSA-OAEP for key wrapping and AES GCM for payload encryption.

CORS Implementation

Setting trusted domains is an important part of the workflow generation process, so review our Cross-Origin Resource Sharing (CORS) documentation to understand how this function helps secure your workflow.

CORS is an HTTP-header based mechanism that allows a server to indicate any other origins (domain, scheme, or port) than its own from which a browser should permit loading of resources. 

Getting and Analyzing the Assertion Response

The assertion response displays the relevant metrics that determine acceptance, rejection or manual review decisions from the Instnt engine.

It also lists the relevant information for the specific customer tied to it, including: first name, last name, mobile number, email, etc., and data and metadata that was processed about the enrolling user's device, biometric behaviors, geolocation, network cohort analysis, KYC and document verification outcomes.

Document Verification

The Document Verification feature is composed of a Javascript library that is injected into your web-app via Instnt's Javascript Agent or the React/Angular SDK's.

This feature also contains user-defined Javascript Callback functions to initialize the Javascript library for Document and Selfie Image capture and to handle both of the base64-encoded captured images
