Other individuals may falsify information.
Companies that shut down will no longer be named publicly, he said.
Nor would figures be released on the number of companies that have closed, or new registrations.
Details of the companies involved would however be passed on to Social Security so real cases could be effectively helped.
Social Security offices in different provinces woulds work together to support those thrown out of work, he said.
So far, 7.1 million people earning less than 15,000 baht a month have collected cheques for 2000 baht each under the government's aid and economic stimulus package.
Another 500,000 to 600,000 had yet to collect cheques, he said.
Cheques that have not been collected by the end of May will return to government funds.
