• and
• a processor to prepare data for sending to a processing service to perform one or more of the following items (a) to (f), wherein any of the items (a) to (f) not performed by the processing service are performed by the processor:
• (a) compare a voice sample of the second party to the voice pattern of the voice certificate, the voice sample being obtained from a currently occurring audio call between the second party and the first party;
• (b) verify the voice certificate;
• (c) verify the attribute certificate;
• (d) verify the at least one attribute signing organization certificate;
• (e) compare the first certificate ID to the second certificate ID;
• and

• (b) comparing a voice sample of the second party to the voice pattern of the voice certificate, the voice sample being obtained from a currently occurring audio call between the second party and the first party;
• (c) verifying the voice certificate;
• (d) verifying the attribute certificate;
• (e) verifying the at least one attribute signing organization certificate;
