Today, the management and use of digital identities have an essential place in many online platforms. However, a critical need when managing these digital identities is for individuals to control and share their personal information securely. At this point, the concept of Selective Disclosure has an important role.

Selective Disclosure refers to the selective disclosure of personal information by an individual. That is, the individual may share only specific data with other individuals or organizations that request the information and avoid disclosing unnecessary or redundant information. This makes it possible to provide necessary information while increasing confidentiality.

Verifiable Credentials provide a solid infrastructure to ensure Selective Disclosure. A Verifiable Credential is a piece of digital identity that verifies that an individual has a specific qualification or knowledge. This piece of identification securely represents the individual’s personal information and can be made available to others as needed.

This controlled and selective information-sharing ability of Selective Disclosure is of great importance in various digital interactions. For example, when signing up for a website, you may only need to verify your age rather than providing the site with your full name and age. In this case, Selective Disclosure allows you to provide the required information to the website while protecting your credential privacy by only disclosing age information.

In addition to increasing digital security, this flexibility provided by Selective Disclosure helps individuals and institutions make information sharing more controlled, efficient and secure. This concept will continue to play an essential role in the future of digital identity management and will be considered a critical requirement for a credential privacy-focused digital world. At this point, we can understand this important issue in depth by taking a closer look at Selective Disclosure’s advantages to individuals and institutions.
