BLOCKCHAIN: Is it the Next Big Step in Data Security?

From Law.Com and its Legaltech news former Microsoft CTO Adrian Clarke (Evident Proof) reports on the technology of Blockchain and its purported major security benefits for the supply ecosystem. “The blockchain is a transaction ledger that is uneditable and virtually unhackable. New information can be written onto the blockchain, but the previous information (stored in what are known as blocks) can’t be adjusted. Every single block (or piece of data) added to the chain is given an encrypted identity. Cryptography effectively connects the contents of each newly added block with each block that came before it. So any change to the contents of a previous block on a chain would invalidate the data in all blocks after it.” Clarke’s report here is perhaps some comfort for an exponentially growing sector of the world wide economy which relies on supply chain management on a massive scale. See his piece in Law Journal Newsletters at 

Attorneys Bill Cheng and John Frank Weaver at McLane Middleton, P.A. in New Hampshire posted this piece in the NH Business Review at: regarding the interaction between Blockchain and Bitcoin and how the GDPR for example will struggle to deal with these technologies, given the protections that GDPR attempts to provide to data owners so that they can control their personal information and data. Blockchain, particularly in conjunction with Bitcoin as the currency for a Blockchain secured transaction will prove a challenge to the GDPR rules. CTOs, Industrial Engineers and Supply Chain designers have big decisions to make in the years to come regarding security and whether Blockchain is the answer to some data protection issues.

From Relecura: Semiconductor Sensors. Building the Wave in IoT Development

As the Internet of Things (IoT) develops, there is an increasing need to “sense” changes in the atmospherics which surround semiconductors. In other words, the working chips must get smarter and smarter and have feel! Some of that AI feel in chips is being supplied by sensing chips – the layered structure of wafers of semiconductor material which can “sense” changes in the environment it is measuring or into which it is placed. Gas sensors are particularly important and patent applications for these devices are on the upswing internationally, with Sony and Samsung leading the way. See Relecura article at
Edaphic Scientific describes a gas sensor’s performance as follows:  “Semiconductor gas sensors rely on a gas coming into contact with a metal oxide surface and then undergoing either oxidation or reduction. The absorption or desorption of the gas on the metal oxide changes either the conductivity or resistivity from a known baseline value. This change in conductivity or resistivity can be measured with electronic circuitry. Usually the change in conductivity or resistivity is a linear and proportional relationship with gas concentration. Therefore, a simple calibration equation can be established between resistivity/conductivity change and gas concentration.”
The IoT relies on smarter and smarter technology as it governs many things around us. Products will have this smarter and smarter technology and converting “sensing” into electronic circuitry will likely have a positive impact on performance, but will present new challenges as products fail and cause damage to person or property. How deep a dive will be required in products liability litigation for example when a “sensor chip” fails to sense. Sensor chips have been around for a while, but they are becoming tremendously sophisticated and integral to the virtual world in which we operate.

Quantum Computing – The Next Tech Frontier – Qubit by Qubit?

(“This superconducting chip, with a total area of one square centimeter, consists of nine qubits in a 1D array. Microwave pusles are applied to control their states and their interaction, and consequently control the dynamics of the system. Such Josephson-junction based superconducting systems are a leading physical implementations for quantum computation and simulation processing. Credit: Eric Lucero/Google, Inc.”

Is Quantum Computing the next Tech frontier? Collaboration between researchers at Google and UC Santa Barbara are working on super computing qubits which might lead to “quantum supremacy” in the computing world. One chief researcher describes it as the desire to “perform an algorithm or computation that couldn’t be done otherwise.” Where classical computers function in two states, zeroes and ones – qubits perform in three states with the extra state being a “superposition” of both zero and one “raising exponentially the number of possible states a quantum system can explore.” For more details see Phys.ORG
