The US arm of HSBC says a problem with its imaging software has exposed sensitive information about customers going through bankruptcy proceedings.
In a document filed last week with the New Hampshire Attorney General's office, the bank says that between 1 May 2007 and 17 October 2008 some Chapter 13 bankruptcy proof of claim forms were not redacted properly.
According to the document, the forms "were viewable by certain computer users as a result of a deficiency in the software used to save imaged documents".
The bank says affected customers of HSBC-run lending subsidiaries were sent letters notifying them of the problem in October and have been offered one year of complimentary credit monitoring.
