Abstract
A data-source computer provides message data, having associated id data, to be sent to a data-collection computer; produces a blinded id by blinding the id data using a nonce; sends the blinded id to a tokenization computer; and sends the nonce and the message data via a network for receipt by the data-collection computer. In response, the tokenization computer produces a blinded token comprising a function, blinded with the nonce, of the id data and a secret key of the tokenization computer, and sends the blinded token to the data-collection computer. The data-collection computer, in response, uses the nonce to unblind the blinded token to obtain an id token which comprises a deterministic function of the id data and the secret key. The data-collection computer then stores the id token and the message data in storage operatively coupled to the data-collection computer.
