iPhone 5S features concerns: Even before Apple ships the new iPhone 5S, the fingerprint sensor in the phone has caused quite a stir in the technological community. Many reputable sources even warn against the use of the function. Hysteria or legitimate concern? "However, before designating the iPhone’s new security feature a win, a few issues need to be considered," says a Sept. 16 Network World report.
You could say that Apple has chosen the worst possible moment for a smart phone with a fingerprint scanner. The NSA scandal after the revelations of Edward Snowden has made many people extremely suspicious over techniques that require personal data. What is needed now is a thorough education so insecure users can better assess the risks of the use of modern means of communication and how to protect themselves from abuse of data.
However, Apple's assertion is that the touch ID will be exclusively stored in the chip of the mobile phone.
Here's what a recent report from Macworld says,
"Does my iPhone store my fingerprint? Apple says no, and here is what I think is going on. Typically, your fingerprint is scanned and run through a mathematical algorithm that creates a fingerprint template. This template is a representation of part of your fingerprint; it isn’t a stored image.
Better yet, most advanced systems run this template through a cryptographic hashing algorithm, as they do for passcodes, and store that result. To add even more security, during hashing it is combined with a unique or random number to make recovery even harder. Since your iPhone already does this with your passcodes (using a special device ID embedded in your hardware), I suspect Apple uses the same process for your fingerprint template. "
Very clear: Basically, the use of fingerprint scanners in smartphones raises the risk of abuse. But technology can make the use of such devices also safer. Ultimately, it comes down to how mature the sensors are used, how and where the biometric data is stored and how they are used. Although Apple has already called a few technical details, but not an exact description supplied with the experts could verify how secure the system is. Similarly, there are no independent tests and studies that could provide insight on how trustworthy the "Touch ID" is.
