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.

Abstract: A computer-implemented method for starting a module of a computerized system comprises: receiving graph data of a direct acyclic graph, DAG, describing the module by way of nodes connected by edges, where at least some nodes are submodule nodes SN, corresponding to submodules of the module, connected via one or more edges reflecting a data dependency between the corresponding submodules, each of which is a hardware module or a software submodule capable of producing and/or consuming data; starting asynchronous execution of two submodules corresponding to two submodule nodes located in independent branches of the DAG, such as one of SN0, SN1, and SN2 together with SN3; determining a third submodule node SN5 that is a descendant of each of the two submodule nodes, according to an outcome of the execution of one or each of the corresponding two submodules, and starting execution of a third submodule corresponding to the third submodule node determined, in view of completing the starting of the module. The DAG may further comprise control nodes VN. Asynchronously executing the submodules may exploit parallelism, to save time at start up. A computer-implemented method for creating graph data of a direct acyclic graph is also provided.
