Hyperledger Membership Service Provider (MSP) Implementation with Identity Mixer Identity Mixer Overview IBM Identity Mixer is a cryptographic protocol suite for strong privacy- preserving authentication features, such as unlinkability and minimal attribute disclosure, efficiently. Briefly, the Identity Mixer protocols work as follows: Setup. The Issuer (Certificate Authority) signing key pair is generated credential issuing authority(ies) (CA). More details on the concepts and features of the Identity Mixer technology are described in the paper Concepts and Languages for Privacy-Preserving Attribute- Based

hyperledger.org/community/project-lifecycle]. Index MSP Implementation with Identity Mixer What is Identity Mixer? In some use cases it will be important to have cryptographic protocols that protect authenticating, and during the transfer of certified attributes. In Fabric this is achieved through Identity Mixer, which has a trust model and security guarantees similar to what is ensured by standard X.509 certificates privacy features such as “unlinkability” and minimal attribute disclosure. Briefly, the Identity Mixer protocols work as follows: Setup. The Issuer (Certificate Authority) signing key pair is generated

Implementation with Identity Mixer: A way to keep identities anonymous and unlinkable through the use of zero-knowledge proofs. There is a tool that can generate Identity Mixer credentials in test environments environments known as idexmigen, the documentation for which can be found in Identity Mixer MSP configuration generator (idemixgen). Setting key-level endorsement policies: Allows the default chaincode-level There are two new capabilities for v1.3: 1. A top-level channel capability that allows Identity Mixer to work. 2. A channel\application capability that enables state-based endorsement. For more information

The Digital Colors Mixer Somewhat hidden away in the Dockers menu (Settings ‣ Dockers ‣ Digital Colors Mixer), this can be a useful tool for off-canvas mixing. The Digital Colors Mixer looks a little bit color of your choosing. By clicking the color buttons below each mixer you can choose a palette of colors to mix with. Above each mixer is a color patch that will produce a color that mixes some amount amount of your current brush color with the palette color. Colors towards the top of the mixer will deliver subtle changes to your current color, while colors towards the bottom will be much closer to the palette
