Method, apparatus, and system for controlling storage of user input information
First Claim
1. In a media gateway (MG), a method for controlling storage of user input information, the method comprising:
- obtaining, from a media gateway controller (MGC), Dual Tone Multi-Frequency (DTMF) digit mask control information, which includes an indication that DTMF digit information may comprise sensitive user input information not suitable for storage;
receiving DTMF digit information; and
based on the indication in the obtained DTMF digit mask control information, deciding not to store the received DTMF digit information.

Abstract
When receiving Dual Tone Multi-Frequency (DTMF) information, we provide a way to determine whether to store such, which may include sensitive user input information. More specifically, a media gateway (MG) obtains DTMF digit mask control information, which indicates whether DTMF digit information may include sensitive user input information not suitable for storage. Based thereon, it decides, whether to store the received DTMF digit 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.

7. A computer program product for use in, or stored on, a media gateway (MG) that controls storage of user input information, the computer program product comprising computer executable instructions stored on a non-transitory computer readable medium in such a way that when executed by a processor, cause the MG to:
-
obtain, from a media gateway controller (MGC), Dual Tone Multi-Frequency (DTMF) digit mask control information, which includes an indication that DTMF digit information may comprise sensitive user input information not suitable for storage; receive DTMF digit information; and based on the indication in the obtained DTMF digit mask control information, decide not to store the received DTMF digit information. - View Dependent Claims (8, 9, 10)
