Instead, according to ABN Amro Mortgage Group CEO Thomas Goldstein, the company will encrypt data and send it over secure networks when possible. Otherwise, it will use special couriers in an effort to avoid another tape loss.

Those changes were announced on the same day the company said it had located the missing tape containing sensitive data about residential mortgage customers, which was lost Nov. 18 while being transported by a delivery service to a credit reporting company. The tape was found Monday, three days after the company began notifying customers that it had been lost.

On Friday, ABN Amro told customers that the tape was lost while being transported by DHL Worldwide Express delivery service from a data center run by a subsidiary of LaSalle Bank Corp. in Chicago to an Experian Information Solutions Inc. credit bureau facility in Allen, Texas. The tape contained the names, account information, payment histories and social security numbers for residential mortgage customers, according to the letter ABN Amro sent customers last week.

Goldstein said during Tuesday's press conference that the search for the tape by ABN Amro, DHL and Experian was 'exhaustive,' and ended last week, at which time they decided to notify customers. Goldstein said the tape was then found Monday. He also said there is still no evidence that the data was misused while it was missing, but he said there's no way to prove the tape wasn't read or copied while it was missing.

Goldstein said that the package containing the missing tape was found in its original sealed container by a DHL employee without the original air bill and that DHL then readdressed the package back to ABN Amro.
