1. A method for performing digital forensics, comprising:
performing, by an electronic device, an analysis of an Internet of Things (IoT) terminal by verifying type, operating system, support function, vulnerability and backdoor, printed circuit board (PCB) and chip-off availability of the IoT terminal to which digital forensics is to be performed;
selecting, by the electronic device, an injection method of injecting a certificate into the IoT terminal, wherein the injection method is any one from among: a method of injecting an image of the IoT terminal into a portable device so that the portable device using the same operating system as the IoT terminal performs the same function as the IoT terminal, a method of emulating the IoT terminal in a pre-installed emulator, a method of connecting with the IoT terminal through an external port provided in the IoT terminal, and a method of injecting an chip which is off in the IoT terminal;
injecting, by the electronic device, a certificate into at least one of the IoT terminal, the electronic device, and a portable device communicating with the IoT terminal using the selected injection method; and
verifying, by the electronic device, data stored in a cloud server communicating with the IoT terminal based on the injected certificate.
