Data overlap count in a multiple tenant database system

A system comprising:

• a memory;
• and
• a processor operatively coupled to the memory, the processor to:
• hash datapoints of a consumer account;
• create a secure view of the hashed datapoints of the consumer account;
• process, using a secure user defined function (UDF), the hashed datapoints of the consumer account and datapoints of a provider account to generate a secure join key, wherein the hashed data points of the consumer account are provided to the secure UDF using the secure view;
• and
• performing an analysis of the hashed datapoints of the consumer account and the datapoints of the provider account of the secure join key.

A non-transitory computer-readable medium having instructions stored thereon which, when executed by a processor, cause the processor to:

• hash datapoints of a consumer account;
• create a secure view of the hashed datapoints of the consumer account;
• process, using a secure user defined function (UDF), the hashed datapoints of the consumer account and datapoints of a provider account to generate a secure join key, wherein the hashed data points of the consumer account are provided to the secure UDF using the secure view;
• and
• perform, by the processor, an analysis of the hashed datapoints of the consumer account and the datapoints of the provider account of the secure join key.
