According to the instructions, the reporter pressed the silicone rubber for 5 minutes, and the whole piece of rubber was loosened after curing from paste. Sure enough, a thumb print has been clearly left on the whole piece of silicone rubber. Dr. Li from the clinic told the reporter that this is the reverse side of the print and can be used to copy the same front as the original.
The doctor said that this kind of silica gel is not uncommon and it is not troublesome to hold. Subsequently, the reporter consulted Taobao. After the input of "medical silicone rubber", a number of similar products appeared, the cheaper ones were only tens of yuan, and the slightly more expensive ones were only 100 yuan.
It is "very convenient" to use and open.
So what is the effect of the mold made of silicone rubber? The reporter took a small piece of plasticine, squeezed out the thumb size, and printed it on silica gel to extract fingerprints. Then, put the "simulated thumb" on mobile phone fingerprint recognition. After some debugging, the lock of the mobile phone was unlocked immediately.
But it can be opened, so can fingerprint identification similar to Alipay transfer be "fooled"? The reporter opened the application and just put the "simulated thumb" on the fingerprint identification interface to confirm the transfer, which showed that the identification was successful.
Subsequently, the reporter used this method to extract the fingerprints of many people and found that they could successfully unlock the mobile phone. It can be seen that the "simulated thumb" made of silicone rubber and plasticine can really "eat" a mobile phone.
In addition, the reporter also found that even after the plasticine is air-dried, the "simulated thumb" made of it can still be easily unlocked.
