Google is promising to monitor its employees more closely to make sure they don't intrude on people's privacy while the company collects and stores information about its users.
The tougher privacy measures announced Friday appear to be in reaction to recent breaches that have raised questions about the Internet search leader's internal controls and policies.
In May, Google Inc. acknowledged that one of its engineers set up a system that scooped up people's e-mails and passwords transmitted over unsecured wireless networks while the company's cars drove around neighborhoods throughout the world. Last month, the company acknowledged firing another engineer who spied on the Google accounts of four minors.
As part of its crackdown, Google will require all 23,000 of its employees to undergo privacy training and impose stricter compliance standards.
