The implementation of Machine Learning (ML) algorithms in fraud detection has proven to be highly effective, leveraging the capability to learn from historical fraud patterns and identify them in future transactions. ML algorithms excel in processing information rapidly and uncovering intricate fraud traits that may elude human detection. This advanced approach is particularly valuable across various industries where fraud detection is paramount in preventing the acquisition of money or property through deceptive means, such as check forging or unauthorized use of credit cards.
Fraud detection is a set of activities undertaken to prevent money or property from being obtained through false pretenses. Fraud detection is applied to many industries such as banking or insurance. In banking, fraud may include forging checks or using stolen credit cards.
Fraud investigations commence with an introductory meeting between the investigator and the client or victim. The individual initiating the investigation articulates the suspicions of deceit, presenting any available evidence to back their claims. A proficient fraud investigator utilizes this initial information as a foundation to uncover additional evidence.
It is noteworthy that individuals who previously defrauded you may attempt to pose as legitimate investigators. Therefore, exercise caution and refrain from placing unwarranted trust unless the person initiating contact provides verifiable credentials (their license, proof of identification, and their personal contact number). Upon confirming the investigator's identity, kindly follow their instructions and provide them with all necessary information to facilitate your case.
Blockchain technology is based on a decentralized model, in which peers collaborate and build trust over a business network. Each peer organization can be represented by one or more nodes and this network of nodes is used to broadcast transactions and reach consensus for each transaction submitted. Each node is supposed to be self-sufficient with the ability to serve any of the distributed applications and/or existing enterprise applications. However, the health of each blockchain node and the entire blockchain network needs to be monitored to ensure truly decentralized and robust operations.
A typical blockchain network comprises of a set of interconnected nodes that act as peers. These nodes usually are hosted on cloud/on premise infrastructure where the blockchain runtime is set up natively on a virtual machine (VM) or by using containerization technologies such as Docker. Transactions submitted to the blockchain network are broadcast to all peers and the new blocks created are propagated, so that all peers have an updated copy of the shared ledger. To gain insight to the block, its transaction related events and associated metadata, monitoring of any one of the peers is sufficient. And that is usually done by using blockchain explorer, which listens to the events and provides some visualization of the number of transactions received, queued, processed and finally grouped into a new block. However, this level of monitoring does not provide any clue to the usage of resources on that node or the health of other nodes or the latency experienced within the blockchain network. Another key element that needs to be monitored to gain end-to-end visibility of a blockchain based solution is the off-chain components that comprises of the dApp (decentralized application) layer. The dApp layer comprises of user interface, storage and API (Application Program Interface) SDK (Software Development Kit) components, through which the interaction with a blockchain node is enabled.
Thousands of operators work tirelessly in front of their desks, supervising and monitoring all and every single transaction taking place on the blockchain system that has either part of it unverified, unsolicited or suspicious due to single or various reasons. These operators make sure the transaction is confirmed manually when the automatic system fails.
Manual supervision may be done with a simple e-mail asking for your confirmation, if urgent, you might also receive a call (Contact information collected from your public exchange platform) to swiftly allow or suspend a transaction taking place under your legal name.
Some organisations will have established specialist counter fraud teams and these standards and guidance are designed to enable those teams to develop their capability in a common way across government that will, over time, increase the ability of these organisations to share resource and practice under a common understanding.
For organisations that make use of more part-time internal investigative resource, the intention is the resource should develop to meet the standards within this document if they do not already. To begin with, an organisation may decide that the foundation standard level in the competency framework is most relevant to their organisation. Over time, these resources have the opportunity to increase their capability against these standards to Practitioner level with the intention of making investigation functions more efficient and effective, and enabling greater crossover between individuals.
