Ex-Googlers Launch iPhone App for Tapping Into Friends’ Reviews

The Spark of Genius Series highlights a unique feature of startups and is made possible by Microsoft BizSpark. If you would like to have your startup considered for inclusion, please see the details here.
Name: Stamped
Quick Pitch: An iPhone app that lets you find and share recommendations with people you trust.

Genius Idea: Although review sites can be handy while trying to secure a last-minute hotel reservation or — deep breath — finding a hair salon in a new neighborhood, nothing evokes more confidence than taking the recommendation of a friend whose tastes you know and trust. But there doesn’t yet exist a convenient platform or library for sharing and storing recommendations with your friends.
Enter Stamped, a Google Ventures-backed iPhone app launched by a team of (mostly) former Google employees this week. The app, which is coming soon to other smartphone platforms as well as the desktop, lets you keep track of and share the things you like. You can also tap into the recommendations of your contacts and well-known tastemakers, such as chef Mario Batali (an advisor to the startup) andNew York magazine.
It works like this: After downloading the app, you’re given 100 stamps, which you can use to recommend restaurants, books, movies and albums, among other things. You can also see what your friends are recommending by authorizing the app to pull in your contacts from your phone, Facebook and Twitter. If someone likes your recommendation, he or she can give it an additional stamp, and you’ll earn two more stamps to give out. Recommendations can also be liked and saved to a do-list.
Pulling up your friends’ recommendations is easy. You can browse by category (such as books) or location (including nearby), the latter of which is displayed conveniently on Google Maps. You can also search for terms like “sushi” or “iPhone app” to hone in further.

Get recommendations from tastemakers such as chef Mario Batali, film critic Peter Travers and fashion designer Rebecca Minkoff.

“People are very prone to sharing and exchanging, there just wasn’t an efficient way to do it,” says cofounder Bart Stein of his team’s desire to create the app.
Like many a startup entrepreneur, CEO and cofounder Robby Stein (who, according to Stamped’s about page, is not Bart’s brother) says he and his team are “100% focused on building a product that delights our users.” They have, however, also recognized immediate opportunities for revenue. When you see a recommendation for a restaurant for instance, you can click through to book a reservation on OpenTable. Likewise, you can purchase movie tickets through Fandango, books through Amazon and songs through iTunes. Stamped has an affiliate relationship with each provider.
So there you have it: a truly useful, beautifully designed app — with a plausible business model — from a talented, well-backed set of young entrepreneurs. This is hands-down one of the most promising startups I’ve seen all year.

Skype iPhone, iPod Touch App Has Security Hole

Skype is working to fix a security hole in its iOS app for the iPhone and iPod Touch that allows a hacker to steal a person’s entire address book. The vulnerability, located in the app’s chat message window, can be exploited with JavaScript code. It was pointed out by security researcher Phil Purviance of AppSec.

"Skype uses a locally stored HTML file to display chat messages from other Skype users, but it fails to properly encode the incoming user’s ‘Full Name,’ allowing an attacker to craft malicious JavaScript code that runs when the victim views the message," Purviance wrote on his blog.

The heart of the problem, according to Purviance, is an improper definition within the Skype app that allows access to a user's local file system. He says the threat is partially mitigated by protections within iOS itself, but the address book remains vulnerable.

Skype appears to be in no hurry to fix the problem. In a tweet, Purviance said he notified Skype of the vulnerability on August 24, and was told that an update addressing the issue would be released in early September.

A statement from Skype confirms that the company is aware of the issue and will fix it "in our next planned release, which we hope to roll out imminently."
