Irish data Commissioner steps up investigation into Yahoo email scanning

Ireland's Data Protection Commissioner (DPC) said on Monday it was trying to ascertain if Yahoo! Inc's decision to scan clients' email accounts at the behest of the U.S. authorities last year broke European law. Sources have told Reuters that Yahoo used a software program to sift through millions of emails for specific information related to national security. At the time last month, the DPC said it was seeking more information from Yahoo.
