Recently, two security researchers have proposed a new method to attack smartphones in seconds.
Costs about $300
Kai Cao and Anil K. Jain from the College of Computer Science and Engineering at Michigan State University can crack smart machines in 15 minutes or less. This method can take a photo of a person's fingerprint, print it out with special ink, and then unlock the phone with the printed model. This method is relatively simple. The two security researchers said their method was shorter than the previous chaotic club proposed to unlock the iPhone 5 s,
In 2013 they said they successfully cracked the iphone 5S fingerprint scanning function, with a host fingerprint of high pixel photos can be identified by Touch ID. At that time, we first took the host fingerprint photo, and the resolution was 2400 dpi. Clear the photo and print it on a transparent template at a resolution of 1200 dpi. Then, apply the emulsion milk or wood glue to the transparent template with fingerprints. After drying, the latex film will slowly break away from the mold, blow the film to make it moist, and finally put the film on the sensor to unlock the phone.
The devices they prepared also include: normal inkjet printers, AgIC kits, a spare black ink cartridge, and specialized AgIC paper. The entire device costs about $300.
AgIC Introduction
A startup company from Japan launched a startup company from Japan to launch AgIC, an ink cartridge directly added to an ordinary ink jet printer, and even converted the ordinary printer into a circuit printer. Buyers of the AgIC DIY kit must own their own inkjet printers to convert them into PCB printers. AgIC also recommends that you purchase a subset of inkjet printer, which can well support specialized injection tools. In addition, users are recommended to purchase a new inkjet printer, instead of using an existing printer that implements standard printing-to avoid cleaning the standard ink in the printer system. AgIC is not The first "Circuit printer" in The world. It used to have a 3D Circuit printer, The EX printer, and The Circuit pen Circuit Scribe on Kickstarter.
Enhanced security of fingerprint recognition Devices
The researchers said anyone could have access to the fingerprint of the mobile phone owner, and even the fingerprint of the mobile phone was stolen. Scan the phone surface with 300 dpi, flip it horizontally, and print the scan results to the smooth side of the AgIC paper. Then they cut down the fingerprint part on the paper and put it on the fingerprint scanning sensor part of the mobile phone (based on the brand). The mobile phone identifies the fingerprint and gives the visitor the permission, then you can access the data on the target mobile phone.
The new methods proposed by Cao and Jain can quickly generate fingerprints, the report said:
"Malicious attackers can quickly use remodeling technology to generate fingerprints, which may be simpler than the previous 2.5D printing technology ."
In the future, we may use more biometric identification technologies, and the number of fingerprint sensor devices is expected to grow rapidly between 2015 and 2020. Cao told Quartz:
"Because more and more mobile phones are using Fingerprint Authentication technology, this is the importance of anti-Fingerprint spoofing technology ."
