Secure E-Health: Managing Risks to Patient Personal Identity

As we are becoming a digital society, it is very important for us to protect the security of personal identity in any transactions. One of the efforts to maintain the security of personal identity is by unrevealed our data more than necessary. Anonymous credential allows an organization to give a credential to a user.
