1. A computer-implemented method for improving caller verification, the method comprising:
registering an intended communication session by hashing a first session-specific information to generate a key;
receiving a second session-specific information;
hashing the second session-specific information to generate a comparison key; and
verifying the intended communication session by comparing the comparison key with the key.
