Participants as requestors using a requesting network element request one or more tokenization processors to generate tokens that represent a sanitized version of data such that the resultant tokens are amenable to comparison across participants. As circumstances warrant, one or more such tokens can be submitted to the tokenization processor(s) to privately retrieve the original data. Role-based access control scope parameters and tokenization processor-specific tokenization processor secrets can be embedded into reversible tokens that remain invariant under updating of the tokenization processor secrets across tokenization processors. By another approach, role-based access control scope parameters and tokenization processor-specific tokenization processor secrets are embedded into tokens and corresponding key tokens such that upon authorized presentation of a token by a requestor, the corresponding key token is recovered so that the keying material that was used to generate ciphertext is retrievable in order to recover the corresponding plaintext.

Method and apparatus for reversible tokenization with support for embeddable role-based access control

The system is a scalable, flexible, and extensible platform for building, deploying, and managing distributed applications that interact with multiple blockchain technologies. The system implements well-defined and well-managed microservices to encapsulate functionality, isolate sensitive data, enable responsive and efficient scaling, and provide a framework for future improvements and support for future blockchain technologies. The system in one embodiment uses an event-driven architecture to construct fast, responsive systems, but still provide support for alternate modes of operation. The system exposes high-level abstractions of the foundational elements of distributed applications in a powerful, well-understood programming environment to simplify development of extensions, adapters, and applications.

Method and apparatus for blockchain management

A protocol that is managed by a coordinating network element or third-party intermediary or peer network elements and utilizes tokens prohibits any subset of a union of the coordinating network element or third-party intermediary, if any, and a proper subset of the processors involved in token generation from substantively accessing underlying data. By one approach, processors utilize uniquely-held secrets. By one approach, an audit capability involves a plurality of processors. By one approach, the protocol enables data transference and/or corroboration. By one approach, transferred data is hosted independently of the coordinating network element. By one approach, the coordinating network element or third-party intermediary or a second requesting network element is at least partially blinded from access to tokens submitted by a first requesting network element. By one approach, a third-party intermediary uses a single- or consortium-sourced database. By one approach, network elements provisioned with tokens jointly manage the protocol.

Method and apparatus for third-party managed data transference and corroboration via tokenization

A coordinating network element manages a protocol that makes attestations of off-platform-resolved data and decisions available for use on a blockchain platform or on another decentralized-execution-based platform operational within a multi-tenant environment. By one approach, these teachings provide for off-platform-verified data pertaining to individual-, group- or machine-based users to be blinded from access by the coordinating network element and by the platform while utilizing a tokenized form of such data to enable user-initiated queries that involve solely on-platform vetting of users as a condition of fulfilling user requests for service.

Method and apparatus for utilizing off-platform-resolved data as an input to code execution on a decentralized platform

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.

Method and apparatus for effecting a data-based activity

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.
