Provided is a multi-verification system and method using multi-communication channels, multi-devices, and multi-random numbers. The multi-verification method receives first personal data inputted to a first device to generate a first random number; compare a random number received from a second device with the first number generated in the first generating step to verify the validity; receives second personal data inputted to a second device to generate a second random number, and compare the random number received from the first device with the second random number generated in the second generating step to verify the validity. By this, users can be authenticated by multi-random numbers based on the personal data inputted through the multi-devices, resolving a security weak point. Also, data is transmitted through the multi-devices and the multi-communication channels, further enhancing security.
