<p>A method, an apparatus, and a system for controlling storage of user input information are disclosed. The method includes: obtaining Dual Tone Multi-Frequency (DTMF) digit mask control information which indicates whether received DTMF digit information is suitable for storage; receiving DTMF digit information; and deciding whether to store the received DTMF digit information according to the obtained DTMF digit mask control information. In this way, the DTMF digit mask control information controls whether to store the user input information on the DTMF digit information processing device in the architecture with the service function being separated from the bearing function, thus avoiding information security risks brought by indiscriminate storage of sensitive contents in the user input information.</p> |
