PRIVACY-PRESERVING IDENTITY DATA EXCHANGE - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240020410 titled 'PRIVACY-PRESERVING IDENTITY DATA EXCHANGE

Simplified Explanation

The abstract describes a method for securely transmitting personal data associated with a user to a relying party. The method involves encrypting the personal data with a public key associated with the user, and then encrypting it again with a public key associated with the relying party. The subsequently encrypted personal data is then transmitted to the relying party computer or user device, which can further transmit it to the relying party computer. The relying party computer can then obtain the personal data from the subsequently encrypted data.

• The method involves receiving a request for personal data associated with a user.
• The personal data is encrypted with a public key associated with the user.
• The encrypted personal data is then encrypted again with a public key associated with the relying party.
• The subsequently encrypted personal data is transmitted to the relying party computer or user device.
• If the user device receives the subsequently encrypted personal data, it can transmit it to the relying party computer.
• The relying party computer can obtain the personal data from the subsequently encrypted data.

Potential applications of this technology:

• Secure transmission of personal data between users and relying parties.
• Protection of personal data from unauthorized access during transmission.

Problems solved by this technology:

• Ensuring the security and privacy of personal data during transmission.
• Preventing unauthorized access to personal data by encrypting it with multiple public keys.

Benefits of this technology:

• Enhanced security and privacy of personal data.
• Simplified and efficient transmission of personal data between users and relying parties.

Original Abstract Submitted

a method is disclosed. the method comprises receiving, by a digital identity computer, a request for personal data associated with a user. the digital identity computer may retrieve encrypted personal data, wherein the personal data is encrypted with a public key associated with the user. the digital identity computer may encrypt the encrypted personal data with a first public key associated with a relying party or derivative thereof to form subsequently encrypted personal data. the method may then proceed to transmit the subsequently encrypted personal data or derivative thereof to a relying party computer, or a user device. if the user device receives the subsequently encrypted personal data, the user device may thereafter transmit the subsequently encrypted personal data or derivative thereof to the relying party computer. then, the relying party computer obtains the personal data from the subsequently encrypted personal data or derivative thereof.
