Building Customer Trust Through Transparency: Public Attestation and Privacy Guarantees
TL;DR:
Customer trust in data privacy is collapsing — only 30% of consumers say they trust organizations to protect their personal information. Public attestation powered by Confidential Computing (TEE) turns trust from promises into cryptographic proof, allowing customers to independently verify how their data is protected.
Enterprises that adopt public attestation report 35–50% higher trust scores, 8–15% higher conversion rates, and clear competitive differentiation in privacy-sensitive markets.
This guide explains how to build customer trust through transparency and verifiable privacy using Phala Cloud.
The Trust Crisis
Current State of Customer Trust
The numbers are stark: - 79% of consumers worry about data privacy (Cisco Privacy Survey 2024) - 30% trust companies to protect their data (down from 42% in 2020) - 86% want more control over their data - 48% have switched companies due to privacy concerns
Cost of trust deficit: - Lost sales: $1.2T globally (customers avoid sharing data) - Higher CAC: 40% more expensive to acquire privacy-concerned customers - Brand damage: Privacy breaches erode trust for years - Regulatory scrutiny: Low trust attracts regulator attention
Why Traditional Trust-Building Fails
Common approaches that don’t work:
| Approach | Company Claim | Customer Reaction | Result |
| Privacy Policies | “Read our 10,000-word privacy policy” | “Too long, don’t trust it anyway” | 0.1% actually read policies |
| Trust Seals/Certifications | “We’re SOC 2 certified!” | “What does that mean? Can you still access my data?” | Customers don’t understand certifications |
| Marketing Promises | “We take privacy seriously” | “Everyone says that. Prove it.” | Promises without proof don’t build trust |
| Transparency Reports | “Here’s our annual transparency report” | “You wrote it. Of course you say nice things.” | Self-reporting doesn’t convince skeptical customers |
Why they fail: All rely on trusting the company. In trust crisis, that doesn’t work.
Public Attestation: Trust Through Proof
How Public Attestation Works
The paradigm shift:
Traditional Approach:
Company: “Trust us to protect your data”
Customer: “But CAN you access my data?”
Company: “Yes, but we promise not to”
Customer: Confidential Computing Approach:
Company: “We literally CANNOT access your data”
Customer: “How do I know?”
Company: “Here’s cryptographic proof: [attestation URL]”
Customer: What customers can verify: - ✅ Data encrypted in hardware (GPU TEE) during processing - ✅ Specific code running (Docker image hash) - ✅ Configuration settings (environment variables hash) - ✅ TEE genuine (Intel/AMD/NVIDIA hardware signature) - ✅ Current status (continuous attestation, 5-minute intervals)
Customer Verification Journey
Step-by-step trust building:
- Customer Learns About Privacy Protection: Marketing page: “Your data is protected by hardware encryption”
- Customer reaction: “Interesting, but is it real?”
- Customer Sees Attestation Link: “Verify our privacy protection: [Public Attestation URL]”
- Customer: “They’re inviting me to verify? That’s unusual…”
- Customer Clicks Through: Trust Center page shows:
- TEE Type: Intel TDX
- Code Hash: sha256:abcd1234…
- Verification: ✓ Valid (verified 3 minutes ago)
- Explanation: “This proves your data is encrypted in hardware”
- Technical Details: [Link for technical users]
- Customer: “They’re showing me proof, not asking me to trust”
- Customer Verifies (Technical Users): Technical customer downloads verification tools
- Runs independent verification
- Confirms: Company literally cannot access data
- Shares findings with decision-makers
- Customer: “I verified it myself. This is real.”
- Customer Trusts and Converts: Trust established through proof, not promises
- Customer comfortable sharing sensitive data
- Higher conversion, better engagement
- Result: +40% trust score, +12% conversion rate
