Google made its apologies last week for weak privacy measures and security practices that resulted in mistakenly collecting unencrypted Wi-Fi data using Street View cars.

While collected information was mostly fragmentary in some cases it included entire e-mail messages, URLs, and passwords, according to a blog post by Alan Eustace, senior vice president of engineering and research.

"We work hard at Google to earn your trust, and we're acutely aware that we failed badly here," he says in his post.

According to Eustance’s post the company took a number of steps to improve and enhance its security which include changes in people, training, and compliance. Thus, Alma Whitten was appointed privacy director for engineering and product management. She will be responsible for making sure effective privacy controls are included in Google products and internal practices.

Besides, the company will also provide enhanced training for engineers which will have "a particular focus on the responsible collection, use and handling of data," Eustance says. Every engineering project lead will also need to have a privacy design document that will regularly be reviewed by managers and an independent audit team, he says. "We believe these changes will significantly improve our internal practices (though no system can of course entirely eliminate human error)."

"We are mortified by what happened, but confident that these changes to our processes and structure will significantly improve our internal privacy and security practices for the benefit of all our users," he says. "We want to delete this data as soon as possible, and I would like to apologize again for the fact that we collected it in the first place."
