Obfuscating audible communications in a listening space

A computer program product stored on a non-transitory computer readable storage medium, which when executed by a computing system, provides obfuscation of audible messages in a listening space, the program product comprising:

• program code that triggers an obfuscation event;
• program code for selecting injector nodes in the listening space for the obfuscation event;
• program code that distributes one or more public keys, derived from a natural interface key, to the injector nodes to cause the injector nodes to inject sounds into the listening space to obfuscate an audible message broadcast by a source node for a target node, wherein timing and content of the sounds injected into the listening space by each of the injector nodes are determined by an associated public key provided to the injector node;
• program code that distributes a decoding key to the target node, wherein the target node extracts the audible message from the listening space using the decoding key;
• and
• program code that calculates the natural interface key using machine learning based on interactions captured from the source node.

A computerized method that provides obfuscation of audible messages in a listening space, the method comprising:

• capturing audible interactions in a listening space;
• triggering an obfuscation event based on detection of an invocation;
• selecting injector nodes in the listening space for the obfuscation event;
• calculating a natural interface key using machine learning based on interactions captured from a source node in the listening space;
• distributing one or more public keys, derived from the natural interface key, to the injector nodes to cause the injector nodes to inject sounds into the listening space to obfuscate an audible message broadcast by the source node for a target node, wherein timing and content of the sounds injected into the listening space by each of the injector nodes are determined by an associated public key provided to the injector node;
• and
• distributing a decoding key to the target node, wherein the target node extracts the audible message from the listening space using the decoding key.
