As an Expert Witness in computer litigation, Dr. Castell has acted in over 100 major cases including the largest and longest computer software actions to have come to trial in the English High Court. He is the author of the best-selling Computer Bluff (1983), and of The APPEAL Report (1990) on the admissibility of computer evidence in court and the 'legal reliability' of information systems and technologies (with the CCTA).
Dr Castell, award-winning international Professional ICT Consultant and Expert has acted as expert witness in an unusual medical equipment procurement litigation of relevance to the current Covid-19 pandemic and its profound clinical and hospitalisation implications. The court case, specific details of which cannot be given since the matter is subject to Confidentiality Hearing strictures, was over a dispute concerning due and diligent process undertaken by a major Hospital Management Group, the Defendant in the action, in issuing a Tender for complex diagnostic units, and the Group’s selection of the bid put in by a US corporation, a leader in its field. That winning bid was challenged by a Claimant, another US corporation, a market competitor to the winning company. The dispute hinged on whether or not the operational computer software of the winning bidder’s units was compliant with the Hospital Management Group’s strict Tender stipulation that the software had to be identical across all versions of the equipment to be supplied in meeting the Tender requirements.
Dr Castell’s investigation and analysis of the operational software involved, and his opinion as to the extent that the software was compliant with the strict Tender condition, provided insight and assistance to the parties in reaching a satisfactory settlement.
In a recent trial, in which I acted as an expert witness, some notable differences appeared to me to emerge, as between UK and USA judicial standards and practices, in regard to the role, obligations, testimony, presentation and rigor of digital forensics expert findings.
The General Data Protection Regulation (GDPR) includes in its provisions Article 17, the Right to be Forgotten, which could potentially be a formidable barrier to the ubiquitous introduction of cryptographic blockchain software and technology.
The new government has announced the areas that it has identified for dramatic cuts in public spending. One of the most effective reductions should be derived through more professional, better-managed government IT spending.
You are an established, reputable, medium-sized corporation. A year ago your board decided to upgrade your existing computer systems by buying a 'unified package', 'lightly-customised', from a 'solution provider'.
Software implementation contracts are frequently terminated with the software rejected amidst allegations from both supplier and customer, e.g. software/database errors/deficiencies, faulty design, shifting user/business requirements. An important technical issue on which the IT Expert appointed in such disputes is asked to give an expert opinion is: what was the quality of the delivered software and was it fit for purpose?
Disputes over failed software construction projects raise interlinked technical and legal issues which are complex, costly, and time-consuming to unravel – whatever the financial size of the claims and counterclaims, the facts and circumstances of the contract between the parties, or the conduct of the software development
This book - "Blockchain Technology and Innovations in Business Processes" - provides a platform to bring together researchers, academia and industry collaborators to exchange their knowledge and work to develop better understanding about the scope of blockchain technology in business management applications of different sectors such as retail sector, supply chain and logistics, healthcare sector, manufacturing sector, judiciary, finance and government sector in terms of data quality and timeliness.

The findings of this expert investigation were clearly reported by Dr Castell to the court and (most unusually) were fully accepted by the Prosecution without any need for cross-examination, assisting in achieving a Not Guilty verdict from the Jury.

Results of this work were reported in the media worldwide and have served as foundation material for discussion in computer science programs throughout the United States and Europe.
Interhack's Cybersecurity Practice helps you to defend your organization.
Cybersecurity is a diverse topic, including data breaches, compliance violations, and corporate espionage. Security failures can undermine confidence in a brand and can result in catastrophic losses through changes in customer behavior, canceled contracts, and stolen trade secrets.
The Interhack system of Cybersecurity Services has six parts.
Vulnerability Assessment - will show you where your systems are vulnerable, and how your systems are impacted by those vulnerabilities.
Penetration Testing - shows you how well your organization detects and responds to active attacks by having our team of experts conduct controlled attacks you authorize.
Information Security Assessment - shows you how well your organization addresses information security, as seen through the prism of relevant industry standards.
Application Security Evaluation - shows you how your security concerns have been identified and are managed through system design and implementation.
Network Traffic Assessment - shows you what is actually on your network, and helps you verify that you have only what you think you have.
Criticality Assessment - provides you a view of your organization's most mission-critical information, where it can be found, and how the organization is impacted by a loss of confidentiality, integrity, and availability.
This book is the story of the formation of the world's most widely-used system to protect sensitive information and how a group of independent cryptographers, civil libertarians, and hobbyists managed to demonstrate the system's weakness in June of 1997, even as the U.S. Congress debated the government's control over cryptography. As one of the coordinators of the DESCHALL project that broke a secret message encrypted with what was then the government standard, Curtin presents a unique insider view of how the project came together and what happened behind the scenes to demonstrate the weakness of the standard and ultimately to usher in the age of unrestricted cryptography.
