Identity
infrastructure
by Yashesh Bharti.

Identity infrastructure work by Yashesh Bharti. The category I keep returning to is proof of humanity that does not require building a new biometric database, so the user can verify they are real without giving the verifier something new to leak.
01Thesis

Identity without enrolment

Most identity stacks force the verifier to hold something sensitive: a stored face template, a passport scan, a phone number tied to a person. The interesting problem is the opposite: how do you give a relying party a strong, cryptographic answer to "is this a real human, right now", without anyone storing the underlying biometric anywhere?

The answer I keep arriving at is signed proof tokens. The biometric stays on the device. The verifier gets a short-lived, signed assertion that liveness was just measured. The product, not the data, is what travels.

02Built

PulseProof

PulseProof by Yashesh Bharti is the production implementation of that thesis. It uses remote photoplethysmography on the device camera to confirm a beating heart in the user's face, evaluates liveness on-device, and emits a signed verification token in under two seconds. SOC 2 Type II, GDPR, HIPAA, ISO 27001, PCI DSS, CCPA, NIST, FedRAMP Ready aligned.

03Where it matters

Use cases

  • AI agent authorisation: proving a real human consented to an agent's action.
  • Financial step-up: wire transfers, account opening, password reset.
  • Healthcare and telehealth login under HIPAA constraints.
  • Marketplaces and dating: catfish and seller-fraud prevention without device fingerprinting.
  • Bot-free platforms: a stronger replacement for CAPTCHA that does not annoy real users.
04FAQ

Identity infrastructure questions

What is identity infrastructure in this context?
The combination of liveness verification, identity binding, and signed assertions that lets a relying party trust a user is a real human, right now, without storing the underlying biometric. Yashesh Bharti's thesis is that the verification token, not the biometric, is the product.
What is PulseProof?
PulseProof is a proof-of-humanity infrastructure built by Yashesh Bharti. It uses remote photoplethysmography from the device camera to confirm a beating heart in the user's face, evaluates liveness on-device, and emits a signed verification token in under two seconds. SOC 2 Type II, GDPR, HIPAA, ISO 27001, PCI DSS, CCPA, NIST, and FedRAMP Ready aligned.
When do teams need identity infrastructure like this?
AI-agent authorisation, financial step-up (wires, account opening, password reset), healthcare and telehealth login under HIPAA, marketplaces and dating to prevent catfishing without device fingerprinting, and bot-resistant flows that do not annoy real users.
