swirec.secure_context
Sets recognizer security levels for protecting confidential data, typically for a single event.
Value |
open, encrypt, suppress DEFAULT: open (no security)
|
How to set |
Shown in precedence order (see Rules of parameter precedence): Set in the browser, using the Vendor-Specific-Parameters header in a RECOGNIZE, DEFINE-GRAMMAR, or INTERPRET request (not SET-PARAMS). |
Usage |
Frequently set by applications for individual recognition events. |
Note the spelling of this parameter: it uses "swirec." and not underscore.
This parameter provides security for confidential data such as identification numbers or passwords that users might provide to applications. It hides the information in call logs and audio waveforms. For a description of protected data types, and the resulting strings and audio written to log files, see Protecting confidential data.
Note: The swirec.secure_context parameter suppresses or encrypts information for the caller's input only. To affect the application's side of the conversation, use the switts.secure_context parameter.
See Security levels to protect confidential data for an overview of how the swirec.mute_wcr, swirec.secure_context, and wcr_encrypt parameters interact with each other.
The security levels are exclusive. You can change between suppression and encryption at any time, but cannot set both simultaneously.
Sample definition in a VoiceXML application where the setting is valid for a single recognition request.
<field name="field1"/>
<prompt>please say password</prompt>
<property name="swirec.secure_context" value="suppress"/>
<grammar><!-- ... --></grammar>
</field>
The browser interprets the application definition in a RECOGNIZE, DEFINE-GRAMMAR or INTERPRET method. To retain elevated security for more than one event, the browser specifies the swirec.secure_context value to subsequent RECOGNIZE, DEFINE-GRAMMAR or INTERPRET requests. Otherwise, the value reverts to the default.
