TIM Plus and TIM Enterprise offer the ability to obfuscate (mask out) one or more sections of the audio of a telephone call with a customisable audible tone, preventing the listener from hearing the original speech when played back.
This is normally required for compliance in certain industries where regulations dictate that certain spoken information be masked out, e.g. the Payment Card Industry - Data Security Standard (PCI-DSS).
In this example, we will adopt the PCI-DSS example where telephone calls that contain spoken credit card information need to be masked out by an audible tone, but only during those parts of the call when the card details are actually being spoken, leaving intact the rest of the call audio.
Our recommended options are:
Call obfuscation tool - chrome plugin. This is used when card details are being entered on-line.
Programmatic obfuscation. For this, we'll assume that agents (employees that make or receive telephone calls) utilise an in-house or third-party data entry system into which credit card detailed are entered using a computer.
