Why is user control key in digital identity?

In the digital era, autonomy over one’s credentials is essential. Users need to decide what to show, when to share, and with whom.
With POK, you’re not forced to disclose all your data. Our platform provides selective presentation tools that let you share only the relevant parts of your credentials, keeping your privacy intact.

What is selective presentation?

Selective presentation means sharing only specific parts of a digital credential without exposing the entire document.

Common examples:

  • Showing that you completed a “Python Programming” certificate without revealing your exact grade.
  • Presenting your university diploma without displaying your ID number.
  • Sharing participation records without sensitive data.

This model aligns with the principles of Self-Sovereign Identity (SSI), where control lies with the user.

How does POK make it possible?

While POK doesn’t yet use advanced cryptographic methods like Zero-Knowledge Proofs (ZKP), it offers a secure and practical approach:

  • Individual credential selection: choose which credentials to display in your POK wallet.
  • Unique shareable link: each credential has its own public URL.
  • Visibility control: disable links or revoke access anytime.
  • Configurable public profile: decide which credentials are visible in your profile.

Security and privacy in your hands

The POK model ensures that:

  • No one can access your credentials without your consent.
  • Only the information you authorize is shared.
  • Issuing institutions cannot expose your data without permission.
  • Shared access can be revoked at any time.

In short: your information, your rules.

The future of selective presentation

POK is developing new features to enhance user control:

  • Share specific attributes without revealing the full credential.
  • Integrate Zero-Knowledge Proofs (ZKP) for minimal data disclosure.
  • Connect with SSI ecosystems and decentralized wallets.

This will elevate privacy and digital trust to a new level.

Practical use cases

Selective presentation already solves real-life scenarios:

  • Job applications: share only relevant certifications.
  • Scholarships and admissions: provide specific requirements without full records.
  • Official procedures: present only the minimum required data.
  • Professional networking: showcase achievements without exposing sensitive info.

Conclusion: Autonomy and trust in your credentials

At POK, we believe that digital trust is built on individual control and respect for privacy.
Our selective presentation model empowers users to decide how, when, and with whom to share their credentials — without exposing unnecessary data.
