ThinkPad notebooks from Chinese computer-maker Lenovo, which already let the user log on with a thumbprint instead of a password, will now allow users to encrypt their hard drives at the press of a finger. The company planned to announce the new security technology on Monday. The program works with Utimaco’s SafeGuard Easy software, which has received certification from the U.S. government for purchase by its agencies, according to Clain Anderson, director of the company’s ThinkVantage technologies.
