Commonwealth Bank of Australia will turn on a new technology system it has developed to use the growing power of AI to root out and prevent people using its electronic payments system to send abusive messages. Since early last year, the bank has been seeking to tackle a problem whereby people depositing funds in another person’s account figured out they could include short messages instead of payment descriptions. These have ranged from harmless jokes to serious cases of the system being used as a targeted form of domestic and family violence. the bank’s AI labs had developed the new system to work alongside the automatic block filter that was implemented last year across its digital banking channels, using machine learning techniques, including capability developed by Google to create a powerful abuse detector. The automatic block will not allow a transaction to be sent if it contains harassing, threatening or abusive language, the sender will be told to remove the offensive language before the transaction can be sent and will have their banking services withdrawn if they continue to send abuse.
