Abstract
A method of validating a passcode in a telephone network comprises using a hash function to hash the directory number of a subscriber to a passcode-controlled service and comparing an entered passcode with the output of the hash function. Each subscriber to a passcode-controlled service is provided with a passcode that is equal to the hash of their directory number produced by a predetermined hash function, and that predetermined hash functions is provided to the various components of the network that may need to validate the subscriber's passcode. Each component of the network is thus able to validate the passcode without performing a database lookup.
