The information displayed in the AIM should not be reported as representing the official views of the OECD or of its member countries.

A bank in Taipei used an AI system to detect suspicious transactions, but it mistakenly froze a customer's account, preventing access to funds. The affected customer protested by making 50 small withdrawals at the counter, highlighting the inconvenience and sparking debate about AI errors and their impact on banking operations and customers.[AI generated]

Why's our monitor labelling this an incident or hazard?

The bank's AI system misjudged and froze the customer's account without valid reason, which is a malfunction of the AI system leading to harm (inconvenience and financial access restriction) to the customer. The incident involves the use and malfunction of an AI system in banking operations. The harm is realized and directly linked to the AI system's erroneous decision. Therefore, this qualifies as an AI Incident under the definition of harm to a person caused by AI system malfunction.[AI generated]

Why's our monitor labelling this an incident or hazard?
The bank's system uses AI or algorithmic detection to identify suspicious transactions and automatically lock accounts to prevent fraud. This automated intervention, while intended to protect customers, resulted in the customer's account being locked erroneously despite normal transaction history, causing harm through denial of access to funds and prolonged account suspension. This fits the definition of an AI Incident because the AI system's use directly led to harm (property harm and disruption of service).

Why's our monitor labelling this an incident or hazard?
The article explicitly mentions the bank's AI detection system causing a false positive that froze the customer's account, which is a direct harm to the individual's financial access and well-being. This fits the definition of an AI Incident because the AI system's malfunction directly led to harm to a person. The customer's protest by making multiple small withdrawals is a reaction to the harm caused but does not change the classification. Therefore, this event qualifies as an AI Incident.

Why's our monitor labelling this an incident or hazard?
The bank's AI system for detecting suspicious transactions caused a false positive that locked a customer's account, directly leading to inconvenience and operational disruption. The customer's response to this malfunction further strained bank operations. The AI system's malfunction is the root cause of the harm, fulfilling the criteria for an AI Incident. Although the harm is not physical injury or legal rights violation, the disruption and harm to the customer's access to funds and the bank's operations are significant and clearly linked to the AI system's malfunction. Therefore, this event is best classified as an AI Incident.

Why's our monitor labelling this an incident or hazard?
The bank's system uses AI or algorithmic detection to identify suspicious transactions and automatically lock accounts to prevent fraud. The account holder experienced direct harm as they could not access their funds or perform transactions, which is a harm to property and financial rights. The incident arose from the AI system's use in fraud detection and risk control, leading to a false positive or overcautious lockout. This fits the definition of an AI Incident because the AI system's use directly led to harm (inability to access funds) and disruption of financial services. The article does not describe a potential or future harm but an actual event causing harm to the user.
