TOKYO, June 23 (Xinhua) -- The western Japanese city of Amagasaki said Thursday it has lost a USB flash drive containing personal information on all of the roughly 460,000 residents in the city in Hyogo Prefecture.
The lost data included information such as residents' names, addresses, dates of birth and the bank account numbers of households that are receiving welfares.
There is no evidence of data being leaked so far, according to the city government.
"We will thoroughly ensure security management when handling electronic data," the city said in a statement.
An employee of a company commissioned to assist the city's COVID-19 relief funds project lost a bag with the flash drive inside after dining and drinking at a restaurant Tuesday, the city said.
The employee reported to police Wednesday. The data were encrypted and protected with a password, according to the city.
"We will work to regain our residents' trust by heightening awareness of the importance of protecting personal information," the city said. ■
