Abstract

A third-party intermediary manages a protocol that prohibits the third-party intermediary 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 as one or more functions of data, parts of which data may be in tokenized or untokenized form, wherein the values of the functions are generated using secrets, at least one of which is unavailable to the third-party intermediary. By one approach, tokens comprised of data in tokenized form are generated using secrets, at least one of which is unavailable to the third-party intermediary.

Claims20

Dependent claims

A method for effecting a data-based activity between network elements, the method comprising:

by a control circuit configured as a stateless third-party intermediary that manages a protocol, wherein the protocol prohibits the third-party intermediary from substantively accessing any tokenized identifiers or entity-related data that, at least in part, underlie a protocol-compliant request;
receiving within a request to invoke the protocol from a first requesting network element acting as at least one of an attestor role and a requestor role a first list of tuples wherein each such tuple includes a blinded function of a tokenized identifier of an entity and wherein each such tuple may include at least one of first metadata and a blinded function of first entity-related data;
receiving within a request to invoke the protocol from a second requesting network element acting as at least one of an attestor role and a requestor role a second list of tuples wherein each such tuple includes a blinded function of a tokenized identifier of an entity and wherein each such tuple may include at least one of second metadata and a blinded function of second entity-related data;
determining a set of values of a blinded function of a tokenized identifier which are included in both the first list of tuples and the second list of tuples;
utilizing at least one subset of the set of values to respond to at least one of the first requesting network element and the second requesting network element, wherein, determination of such a subset may be dependent, at least in part, on consideration of the first and/or second metadata, if any;
and wherein formulation of a response may be dependent, at least in part, on consideration of values of a blinded function of the first and/or second entity-related data, if any.

3 more elements

An apparatus to effect a data-based activity between network elements, the apparatus comprising:

a network interface;
a control circuit operably coupled to the network interface and configured as a stateless third-party intermediary that manages a protocol, wherein:
the protocol prohibits the third-party intermediary from substantively accessing any tokenized identifiers or entity-related data that, at least in part, underlie a protocol-compliant request;
and wherein the control circuit is further configured to:
receive via the network interface and within a request to invoke the protocol from a first requesting network element acting as at least one of an attestor role and a requestor role, a list of tuples wherein each such tuple includes a blinded function of a tokenized identifier of an entity and wherein each such tuple may include at least one of first metadata and a blinded function of first entity-related data;
receive via the network interface and within a request to invoke the protocol from a second requesting network element acting as at least one of an attestor role and a requestor role, a list of tuples wherein each such tuple includes a blinded function of a tokenized identifier of an entity and wherein each such tuple may include at least one of second metadata and a blinded function of second entity-related data;
determine a set of values of a blinded function of a tokenized identifier which are included in both the first list of tuples and the second list of tuples;
utilize at least one subset of the set of values to respond to at least one of the first requesting network element and the second requesting network element, wherein, determination of such a subset may be dependent, at least in part, on consideration of the first and/or second metadata, if any;
and wherein formulation of a response may be dependent, at least in part, on consideration of values of a blinded function of first and/or second entity-related data, if any.
