A mechanism is provided for secure sensitive private information dependent transactions. A query and a transaction token S associated with a current transaction between a SPI owner and the service provider is received. Particular SPI required is identified based on the query. A request for the particular SPI from the SPI owner is constructed thereby forming a constructed request. The constructed request is sent to one or more authorized devices associated with the SPI owner enrolled with the cognitive SPI broker. The particular SPI is received from a device of the SPI owner thereby forming received SPI. The received SPI is used complete the transaction. A notification is then sent to the SPI owner that the transaction has been completed.
