In this age of Internet of Things, if there is equipment that can't be connected, it is really out, can't keep up with the times, the traditional access control is the same, the traditional access control also connected to the network cable in this era, officially entered the Internet era, The upgrade became a two-dimensional code access control. However, there are many people who are worried about this because access control is used to manage the entry and exit of various important channels. If it is cracked, it will cause very big security problems. In fact, these concerns are normal, but in fact, there are many discussions and solutions in the industry. The following are the two-dimensional code access control work on security measures, used as a choice for everyone to choose QR code access control. reference.
Dynamic QR code
The main reason why many people do not consider the two-dimensional code access control is that the two-dimensional code leaks out due to screenshots or photographing. After leaking out, you can open the access control by taking a screenshot or taking a photo of the QR code. In fact, this kind of worry is unnecessary, because many QR codes are now using dynamic QR codes. Dynamic QR codes are time-sensitive. The QR codes will change with time, every time they are opened. The QR code is different. The screen capture or the QR code is not useful and will expire because it exceeds the time. However, there are also some two-dimensional code access control using static two-dimensional code on the market, and the security is very low.
RC4 algorithm encryption
Those skilled in the art of RC4 algorithm encryption know that the encrypted data of the RC4 algorithm cannot be cracked without the secret key. The Seberus QR code access control uses the RC4 algorithm to encrypt the two-dimensional code. The encrypted two-dimensional code has no way to decrypt without the secret key, and the security is greatly enhanced.
Data transmission encryption
In the Internet age, data transmission must be encrypted to prevent tampering during transmission. If the QR code access control is deployed in the cloud, then data transmission encryption is a must. If the data transmission is not encrypted, the hacker intercepts the data, the hacker tampers with the relevant data, and then transmits it to the access control system, which is equivalent to controlling the entire access control system, which is a very dangerous thing. The Seberus QR code access control uses encryption algorithms to encrypt data during transmission to prevent data from being tampered with during transmission.
Tamper alarm
Sebrus QR code access control with tamper alarm function, tamper alarm as the name suggests is to notify the relevant personnel when the device is forcibly removed. The tamper alarm for the two-dimensional code access is notified to the relevant personnel by sound and through the Internet. When the two-dimensional code access control is forcibly removed, the device will emit an audible alarm, and the relevant information will be transmitted to the background through the Internet, and the background can be pushed to the relevant personnel by itself.
