Claim:
1. A method for determining if an ambulatory sleep monitoring device was used by someone other than a proper subject, the method comprising: receiving biometric data from the proper subject's attended diagnostic session; generating a first biometric signature specific to the proper subject from the received biometric data from the proper subject's attended diagnostic session; receiving sleep apnea data from a subsequent unattended diagnostic session, the sleep apnea data received from an ambulatory sleep monitoring device; generating a second biometric signature from the received sleep apnea data from the subsequent unattended diagnostic session; determining if the second biometric signature matches the first biometric signature; determining the ambulatory sleep monitoring device was used by someone other than the proper subject if the second biometric signature does not match the first biometric signature and invalidating or terminating the analysis of the sleep apnea data; and determining the ambulatory sleep monitoring device was used by the proper subject if the second biometric signature matches the first biometric signature and validating or continuing the analysis of the sleep apnea data to determine if the proper subject has sleep apnea.
