Abstract: A method, device and system for authentication in accordance with a SIM card is provided in the present disclosure. The method for authentication in accordance with the SIM card includes the following steps. First, the SIM card receives a feature code of a biometric feature information. Afterwards, the SIM card compares the feature code of the biometric feature information and a feature code stored in the SIM card for obtaining a comparison result. Afterwards, the SIM card returns the comparison result. Compared to existing technology, the above technical solution is configured to store the feature code in the SIM card and use it for authentication. The noncrackable SIM card protects a security of biometric feature information. After replacing the device, just plug the SIM card into the new device to complete the authentication and initialization of the new device. Therefore, the above technical solution avoids the initial setup of the new device and make it easy to use.
