A system for equality testing, the system comprising a first client device including a first private data unit, a second client device including a second private data unit, and a server. The server receives a first obfuscated data unit corresponding to the first private data unit from the first client device, and a second obfuscated data unit corresponding to the second private data unit from the second client device. The server performs a vector calculation based on the first and second obfuscated data units to generate a combination of the first and second obfuscated data units. The server sends the combination to the first client device. The first client device is configured to determine whether the first private data unit is equal to the second private data unit based on the combination.

Vectorial private equality testing

A computing system includes: an initialization module configured to generate initial sharing options; a rating analysis module, coupled to the initialization module, configured to generate a privacy score and a benefit score with a control unit for one or more of the initial sharing options; a mapping module, coupled to the rating analysis module, configured to generate a map based on the initial sharing options, the privacy score, and the benefit score; and a tuning module, coupled to the mapping module, configured to: analyze an initial distribution of the map, and generate the tuned sharing options based on the initial distribution for displaying on a device.
