Personal details of another 7,000 people in the UK may have gone missing after two more organisations admitted to a breach of data security.

The largest of the latest incidents is at the Driver and Vehicle Licensing Agency (DVLA) in Northern Ireland which lost two discs containing details of more than 6,000 car owners, according to BBC News. The discs went missing after being posted to the DVLA head office in Swansea. The data was not encrypted, and included details of vehicle ownership but no financial information.

Last week the agency also admitted to sending confidential information by post to the wrong people, affecting about 100 drivers.

The other incident took place at Leeds Building Society where 1,000 employees’ salary and banking details have been “unaccounted for” after an office move. But the company said it believes there is no evidence that the information has been taken out of the building.

The loss of personal data and potential breaches of the Data Protection Act have come under greater scrutiny in the past few weeks since HM Revenue and Customs admitted to losing two discs containing information about 25 million people in the UK’s largest ever personal data security loss.
