How can I add read/write access permission in Hyperledger Fabric?

Question

How can I add read/write access permission while enrol/register new user using fabric_client/fabric_ca_client or is it possible?. As we have ACL in Hyperledger Composer to allow read/write access, is there any ACL in Hyperledger Fabric?

Answer 1

Although there are no ACLs in Fabric 1.0, Fabric 1.1 has a new feature known as Attribute-Based Access Control. This can be used to implement ACLs in chaincode. 

In the chaincode, you can retrieve the attributes of the enrollment certificate to allow or disallow accesses that are based upon those attributes.
