Abstract
A data verification method and system is provided. The data verification method includes the steps of transmitting data from a sender to a receiver over a signaling channel, transmitting a first set of bits to the receiver over a voice channel, wherein the first set of bits is generated using the data in the sender, and verifying the data through comparison between the first set of bits and a second set of bits that is generated based on the data in the receiver. The first and the second sets of bits may be a group of bits that are selected from a hash value using a selection mask in the sender and the receiver respectively, wherein the section mask has the same length as the hash value and the hash value is calculated based on the data, and the selection mask may be pre-defined between the sender and the receiver.
