A zero-knowledge proof of identity protocol is a special cryptographic algorithm for identity verification. The security of most of the zero-knowledge proof of identity protocols is based on complex mathematical algorithms and requires heavy computations for both parties involved, the proverb and the verifier. Thus, the two parties must depend on computing devices (computers) to perform these computations. Visual cryptography is a special kind of the cryptography that does not require one to know the cryptography and the corresponding complex mathematical computations. In this paper, we propose a new method of zero-knowledge proof of identity based on a non-expansion visual cryptography to overcome the disadvantage of complex computation in the current zero-knowledge proof of identity protocols, thus overcoming the dependence on computing devices.
