Differential privacy for axe obfuscation

A computing apparatus for preserving privacy with respect to information, the computing apparatus comprising:

• a processor;
• a memory;
• and
• a communication interface coupled to each of the processor and the memory,
• wherein the processor is configured to:
• obtain, via the communication interface, first information to be included in a first inventory axe list of available securities;
• obfuscate the obtained first information by applying an algorithm to the first information;
• and
• publish the first inventory axe list by transmitting, via the communication interface, the obfuscated first information to a plurality of intended recipients,
• wherein the first information to be included in the first inventory axe list includes an identification of a first security, a number of shares of the first security that are available to be bought, an identification of a second security, and a number of shares of the second security for which an offer to buy is available.

A non-transitory computer readable storage medium storing instructions for preserving privacy with respect to information, the storage medium comprising executable code which, when executed by at least one processor, causes the at least one processor to:

• obtain first information to be included in a first inventory axe list of available securities;
• obfuscate the obtained first information by applying an algorithm to the first information;
• and
• publish the first inventory axe list by transmitting the obfuscated first information to a plurality of intended recipients,
• wherein the first information to be included in the first inventory axe list includes an identification of a first security, a number of shares of the first security that are available to be bought, an identification of a second security, and a number of shares of the second security for which an offer to buy is available.
