This book is your go-to reference on how to achieve PCI compliance. With more than 400 PCI requirements, the updated PCI Data Security Standard (PCI DSS) v4.0 does not detail the specific documentation that a PCI auditor¿known as a Qualified Security Assessor (QSA)¿needs to know. This book is the first reference to detail the specific documentation needed for every PCI requirement. The authors provide real-world examples of complying with the 12 main PCI requirements and clarify many of the gray areas within the PCI DSS.Any merchant or service provider that stores, processes, or transmits credit card data must comply with the PCI Data Security Standard. PCI DSS 1.0 was first published in 2004, yet many of those tasked with PCI compliance still encounter difficulties when trying to make sense of it. PCI DSS version 4 was published in March 2022, and at 360 pages, it has numerous additional requirements, leaving many people struggling to know what they need to do to comply.PCI DSS v4.0 has a transition period in which PCI DSS version 3.2.1 will remain active for two years from the v4.0 publication date. Although the transition period ends on March 31, 2024, and may seem far away, those tasked with PCI compliance will need every bit of the time to acquaint themselves with the many news updates, templates, forms, and more, that PCI v4.0 brings to their world.What Yoüll LearnKnow what it takes to be PCI compliantUnderstand and implement what is in the PCI DSSGet rid of cardholder dataEverything you need to know about segmenting your cardholder data networkKnow what documentation is needed for your PCI compliance effortsLeverage real-world experience to assist PCI compliance workWho This Book Is For Compliance managers and those tasked with PCI compliance, information security managers, internal auditors, chief security officers, chief technology officers, and chief information officers. Readers should have a basic understanding of how credit card payment networks operate, in addition to basic security concepts.

This book presents state-of-the-art blockchain and AI advances in health care. Healthcare service is increasingly creating the scope for blockchain and AI applications to enter the biomedical and healthcare world. Today, blockchain, AI, ML, and deep learning are affecting every domain. Through its cutting-edge applications, AI and ML are helping transform the healthcare industry for the better. Blockchain is a decentralization communication platform that has the potential to decentralize the way we store data and manage information. Blockchain technology has potential to reduce the role of middleman, one of the most important regulatory actors in our society. Transactions are simultaneously secure and trustworthy due to the use of cryptographic principles. In recent years, blockchain technology has become very trendy and has penetrated different domains, mostly due to the popularity of cryptocurrencies. One field where blockchain technology has tremendous potential is health care, dueto the need for a more patient-centric approach in healthcare systems to connect disparate systems and to increase the accuracy of electronic healthcare records (EHRs).
