PROBLEM data security has become an important issue among smart phone users. Even iPhone users' data was easy to track.
A researcher Aldo Cortesi information technology have found a security flaw in IOS applications, which connect an anonymous unique identifier in the rankings (UDID), with the identity of users daily.
Unlike cookies, blocks of text to save the settings or preferences of a visited there, can be deleted from your computer or mobile phone. Moreover UDID system is permanent. Third parties such as application developers, advertisers can track the applications that use the iPhone users. The result of the investigation last December by The Wall Street Journal found 56 of 101 popular iPhone application is transmitted to the UDID, without the consent and knowledge of the user. Although UDID not contain personal data, there is the possibility of another iPhone user data stored on these devices.
Cortesi noted that Apple explicitly prohibits UDID connects developers with user accounts.
By using OpenFeint, social gaming service that connects to popular games such as TinyWIngs and Unicorn Robot Attack, Cortesi can link the specific personal data to the profile picture and user ID up directly to UDID iPhone.
''If the user gives OpenFeint access to location data, this service can connect UDID with GPS coordinates,''added Cortesi. (huffingtonpost / * / OL-10)
