Telephone and method of transmitting caller token
First Claim
Patent Images
1. A telephone comprising:
- a voice input unit for inputting an audio signal;
a user token input unit for inputting a user token that is data proving an identity of a user;
a user reference storage for storing a user reference that is data used to verify the user token;
a user verifier for verifying the user token on the basis of the user reference stored in the user reference storage;
a caller token storage for storing a caller token that is data proving an identity of a caller; and
a caller token embedder for embedding, upon successful verification of the user token, in the audio signal the caller token stored in the caller token storage.

Abstract
The user token input unit accepts an input of a user token from a user. The user verifier reads a user reference from the user reference storage and verifies the user token on the basis of the user reference. When the verification of the user token is successful, the caller token embedder reads a caller token from a caller token storage and embeds the caller token in an audio signal. The caller token extractor extracts a caller token from a received audio signal. The caller verifier reads a caller reference from the caller reference storage and verifies the caller token on the basis of the caller reference. Verification output unit outputs the result of the verification.
