Title: Handset with hidden
authorization function of the correspondent in telecommunications links The problem the
inventor(s) wanted to solve: Description: Presented device serves for Personal Identification Number
(PIN) sending, in binary signature form assigned to dedicated subscriber,
over telecommunications links.
Personal Identification Number is mapped by watermark signal.
Watermark signal is transmitted together with host’s speech signal and
Watermark is completely perceptually transparent for Human Auditory System
(inaudible) at host’s speech signal presence. Presentation:
Poster Fields of
application: System is dedicated to use in interaction
with military battlefield radio stations VHF and HF radio band as well as
commercial Internet telephony (Voice Over IP), public switched telephone
network (PSTN) and cellular telephony (GSM). Advantages: In
this handset watermark technology is used. Watermark signal is robust for
degradation factors appeared in telecommunications links e.g.: Additive White
Gaussian Noise, resampling, requantisation,
jitter, lossy compression. At the receiver side
watermark is decoded and received binary signature (PIN) is compared in data
base handset. In the case of conformity of received PIN to the original one,
the subscriber is authorized during connection (call). In this case at the
handset’s LCD display right message is shown. Stage of
development: Documentation
