Google Wave, Google's new real-time collaboration platform currently in private beta, is claimed to be more secure than traditional email because Google has focused on addressing privacy and security issues as the product was built from the ground up instead of waiting to deal with them later.
GOOGLE has acquired reCAPTCHA, a company that produces the squiggly words used by websites to guard against spam and fraud.
reCAPTCHA's technology would be used to increase fraud and spam protection for Google products "but also to improve books and newspaper scanning process."
