According to one embodiment, a semiconductor device includes a first system including a first operation circuit, and a second system configured to control a debug operation in the first system. The semiconductor device includes a normal mode and a debug mode. In the debug mode of the semiconductor device, in a case where a first key received from an outside corresponds to a second key stored in the second system, the second system transmits a debug command to the first operation circuit.

A computer system that interfaces with a blockchain is provided. The computer system receives match data for a match between a first data transaction request that is associated with a first identifier and a second data transaction request that is associated with a second identifier. A first blockchain transaction is generated based on the match data and stored to a blockchain. At least one further blockchain transaction is generates that splits the match into two different transactionsone between the first identifier and an intermediary and the second between the intermediary. These are recorded to the blockchain via the further blockchain transactions.

A system and method for block reconciliation of interactions comprising a network-connected block reconciliation computer connected to a plurality of connected devices and to one or more blockchains to enable an object compiler to receive a plurality of criteria from a requesting device. The compiler the receives a plurality of blocks from the public ledger blockchains based on the criteria. Each block corresponding to a preconfigured interaction object previously written by devices either during or after the completion of a transaction. The compiler analyzes the preconfigured interaction objects to determine if there is corresponding supplemental object. The compiler requests the supplemental blocks from the blockchains, and processes supplemental objects based on type, if no corresponding supplemental object it found, the associated interaction object is flagged.

Generating non-compressible data streams is disclosed, including: receiving a sequence comprising a plurality of byte values calculated from an initialization parameter and a constrained prime number; determining a data structure index from a plurality of bits within at least one of the plurality of byte values; retrieving a rotation value from a data structure, wherein the rotation value is stored in the data structure at the data structure index; and rotating a portion of the sequence based on a rotation value to form a rotated sequence, wherein the rotated sequence comprises byte values substantially defeating a predictive compression algorithm.

A system for performing issue tracking using blockchain includes a plurality of computer nodes, the plurality of computer nodes forming a distributed network. Each of the computer nodes communicates directly with the others, and is operated by a user in accordance with a common smart contract. Contributions of each of the users are entered into the blockchain at respective computer nodes as blocks when issue transactions have been completed in accordance with the following steps: entering issue parameters for an issue transaction associated with a stakeholder for an issue to be tracked; submitting the issue parameters to the distributed network to complete the issue transaction to add a block with the issue parameters to the blockchain; detecting by the distributed network of the submission of the issue parameters; and adding the issue parameters as a block to the blockchain.

A method for facilitating employment and education verification is disclosed using Blockchain technology. The method includes: a user submitting a change or an update to their online resume using Blockchain. At its core, Blockchain is a network of computers, all of which must approve a transaction has taken place before it is recorded, in a chain of computer code; the Users Update is recorded in a Block and made available to all the relevant parties on the network to validate the Users claim regarding the latest update (eg change in title at current company); when all the relevant parties validate the claim, the change is recorded as a permanent record. In this methodology using Blockchain, the information is transparently held in a shared database, without a single body acting as middleman and once the final change is recorded as it cannot be altered or changed. There can only be additions to this data.
