Abstract
A coordinating network element manages a protocol that prohibits the coordinating network element from substantively accessing data content that, at least in part, underlies received protocol-compliant requests. By one approach, these teachings provide for preventing substantive access to data information that is included within the protocol-compliant request in tokenized form, wherein the tokens are generated using secrets, at least one of which is unavailable to the coordinating network element.
Claims28
A method for effecting a data-based activity via a network, the method comprising:
- by a coordinating network element that manages a protocol:
- receiving, via the network and from a requesting network element comprising one of:
- a network element that is acting within an attestor role, and
- at least one secondary network element that is acting within a requestor role;
- a protocol-compliant request wherein at least part of data information that, at least in part, underlies the protocol-compliant request is in tokenized form resulting, at least in part, from one or more tokens that are generated jointly by a plurality of processors each accessing a secret as one of a plurality of secrets used for token generation via encryption that uses a symmetric key cipher, at least one of which secrets is unavailable to the coordinating network element, wherein the data information within a first tokenization request, as a first request for one or more tokens made to a first processor, is blinded from the first processor via encryption that uses the symmetric key cipher;
- wherein the data-based activity comprises, at least in part and by the coordinating network element, at least one of:
- transference, to the at least one secondary network element acting within the requestor role, of data content, as data content that was referred to by data information that was previously attested to via one or more protocol-compliant requests received by the coordinating network element from one or more network elements acting within the attestor role;
- and
- corroboration, provided to the at least one secondary network element acting within the requestor role, of the data content, as candidate data content, against the data content that was referred to by data information that was previously attested to via the one or more protocol-compliant requests received by the coordinating network element from the one or more network elements acting within the attestor role;
- wherein the transference and the corroboration occur without divulging of identities of the one or more network elements acting within the attestor role to the at least one secondary network element acting within the requestor role, and without divulging of identities of the at least one secondary network element acting within the requestor role to any of the one or more network elements acting within the attestor role.

An apparatus configured to effect a data-based activity via a network, the apparatus comprising:
- a network interface;
- a control circuit configured as a coordinating network element that manages a protocol by:
- receiving via the network interface and from a requesting network element comprising one of:
- a network element that is acting within an attestor role;
- and
- at least one secondary network element that is acting within a requestor role;
- and via a protocol-compliant request wherein at least part of data information that, at least in part, underlies the protocol-compliant request is in tokenized form resulting, at least in part, from one or more tokens that are generated jointly by a plurality of processors each accessing a secret as one of a plurality of secrets used for token generation via encryption that uses a symmetric key cipher, at least one of which secrets is unavailable to the coordinating network element, wherein the data information within a first tokenization request, as a first request for one or more tokens made to a first processor, is blinded from the first processor via encryption that uses the symmetric key cipher;
- wherein the data-based activity comprises, at least in part and by the coordinating network element, at least one of:
- transference, to the at least one secondary network element acting within the requestor role, of data content, as data content that was referred to by data information that was previously attested to via one or more protocol-compliant requests received by the coordinating network element from one or more network elements acting within the attestor role;
- and
- corroboration, provided to the at least one secondary network element acting within the requestor role, of the data content, as candidate data content, against the data content that was referred to by data information that was previously attested to via the one or more protocol-compliant requests received by the coordinating network element from the one or more network elements acting within the attestor role;
- wherein the transference and the corroboration occur without divulging of identities of the one or more network elements acting within the attestor role to the at least one secondary network element acting within the requestor role, and without divulging of identities of the at least one secondary network element acting within the requestor role to any of the one or more network elements acting within the attestor role.
