1 Functions

The Service Participant Authentication (PAF-SPA) AIM receives the Identifier of a Participant in a Service Session, the Face and/or speech segment of the Service Participant and produces an Identifier of a Service Subscriber:

Receives Participant ID ID of a Participant in a Service Session.
Face Visual Object The Face of the Service Participant.
Speech Object A speech segment of the Service Participant.
Uses Face and Speech Object To find the correspondence between the Participant ID of a Participant requesting access to Service and the Subscriber ID of the Service Provider.
Produces Subscriber ID The Subscriber identified by the PAS-SPA AIM.

8 Conformance Testing

Table 2 provides the Conformance Testing Method for PAF-SPA AIM.

If a schema contains references to other schemas, conformance of data for the primary schema implies that any data referencing a secondary schema shall also validate against the relevant schema, if present and conform with the Qualifier, if present.

Table 2 – Conformance Testing Method for PAF-SPA AIM

Receives Participant Identifier Shall be string.
Speech Object Shall validate against Speech Object Schema.
Speech Data shall conform with Speech Qualifier.
Face Visual Object Shall validate against Visual Object Schema.
Speech Data shall conform with Visual Qualifier.
Produces Subscriber Identifier Shall validate against Instance ID Schema..

9 Performance Assessment

Performance Assessment of a PAF-SPA AIM Implementation shall be performed using the subsets of two datasets of:

  1. Speech segments all in the same language for each segment of which the Identity of the Speaker is provided with reference to a Taxonomy.
  2. Faces for each face of which the Identity of the face is provided with reference to a Taxonomy

for which the identity of a speech segment’s speaker is univocally connected to the identity of a face and vice-versa.

The Performance Assessment Report of a PAF-SPA AIM Implementation shall include:

  1. The Identifier of the PAF-SPA AIM.
  2. The identifier of the speech segment dataset.
  3. The identifier of the face dataset.
  4. The Taxonomy of speaker identifiers.
  5. The Taxonomy of face identifiers.
  6. The Accuracy of the Service Participant Authentication AIM defined as the number of correctly recognised pairs of speech segments and faces of the same Speaker and Face to the total number of submitted Speech and Face pairs..
