A method of auditing operation of a cable television appliance consistent with certain embodiments involves detecting an event that triggers an audit; generating a fingerprint value,wherein the fingerprint value is function of the cable television network characteristics at an authorized installation location; comparing the fingerprint value with a stored reference value; if the fingerprint value is within specified limits of the stored reference value, permitting the cable television applicance to carry out a normal operational function; and if the fingerprint value is outside of spsecified limits of the stored reference value, inhibiting the cable television applicance from carrying out a normal operational function. This abstract is not to be considered limiting, since other embodiments may deviate from the featurs described in this abstract. ® KIPO & WIPO 2007
