Modern science and technology are changing with each passing day, and various black technologies are emerging in endlessly. Thanks to the development of technology, mobile phones, tablets, PCs and other functions are becoming more and more powerful. Especially mobile phones and tablet computers, because of their portability and rapidity, many functions are gathered in a small space, such as photographing, storage, communication, communication, sending files, online shopping, bank payment, bank transfer and other functions involving personal privacy. However, as long as the system is involved, there will be various loopholes, The criminals have developed various rogue software, virus software and trojan software by taking advantage of various system loopholes, lured users to install these software by means of camouflage and deception, and then used various system loopholes to invade your mobile phone, tablet PC and other hardware are hard to guard against. If you are not careful, you will be attacked, endangering personal privacy and property security. From time to time, we will hear about the occurrence of various doors, and some people even have property losses due to the loss of privacy. In order to protect their privacy and property security from threats, people can only install a variety of security software. However, the installation of a large number of security software will also slow down the operation of mobile phones, and mobile phone antivirus software may not be able to detect and remove these junk software. Although we have been very careful to protect our privacy, as the saying goes, we cannot guard against thieves in a thousand days. It is not possible to say when one carelessness will cause losses. Is our secret so exposed that it cannot be protected? Of course not. Now I will introduce you a security tool, the Security Shield.

An Si Mi Dun is a security tool that combines hardware and software developed by Hangzhou An Si Yuan Technology Co., Ltd. It consists of an An Si Mi Dun for mobile APP and a matching hardware An Si Mi Dun.

First, let's take a look at the hardware, the security shield. The packaging of Andersen MyShield is a white paper box. The front of the paper box is only the logo of Andersen, which is very simple. Because the trial version of Leifeng is obtained this time, the trial logo of Leifeng is posted in the front blank. On the side is the slogan of the security company: secure communication, starting from the security company's confidential letter.

On the back of the packing box are the QR code downloaded from the ANS confidential letter APP and various parameters of the ANS confidential shield, as well as the official website, address and contact information.

Open the packaging box, you can see that there is a layer of protective cotton on the packaging box, and there is also a cover inside. Open the internal flip to see the main body of the product. We can see that the main body of the product is placed in the protective cotton to protect the host from damage due to vibration during movement and transportation. It can be seen that the manufacturer is very careful in packaging. There is a small box below, which is the data cable and charging cable of the host, The length is only about 10cm. There is a small ring on the top, which can be hung on the key ring . The data line is Micro USB interface, common with mainstream data cables on the market, The product manual is under the MyShield protective cotton. The manual is relatively simple, which is too simple for people to understand.

Ansmiton has four colors to choose from: green, gray, bronze and blue. This time, the author got a blue host. The whole Midland is round, and a black hanging ring is fixed on it. The hanging ring is printed with the product logo and the official website akey.me, which can be hung on the key ring for easy carrying.

In the white ring of the product center, there is a MiShield switch button, and there are red, blue, and green LED indicators. The product uses the micro USB interface for charging, which is common to the mainstream data cable on the market, and has a buzzer. If it is too hidden, you can find the secret shield through the buzzer.

Only MyShield can not work. It must be used in conjunction with the security letter of Android to reflect the powerful functions of MyShield. We can download it by scanning the QR code on the back of the packaging box, or by searching the security letter of Android application market. After downloading and installing, you need to register an account first.

After registering and logging in, let's first learn about the functions and usage of confidential messages. Click the "I" icon in the lower right corner of the page → Settings → About confidential messages → Function introduction.

After knowing how to use the secret letter, we need to bind the mobile phone with the secret shield. Return to the setting page, click Security Settings, and after entering, the system will automatically search for the password that has been turned on and request to set the password.

The secret shield has been bound, and we can use it for encrypted communication. First of all, we need to enable the security mode. Many functions can only be used in the security mode. First, click a shield lock icon in the upper right corner of the APP, and then enter the password of the secret shield. If it is correct, the security mode will be turned on. After the security mode is turned on, the icon will turn green.

The secret shield has been set. We can start encrypted chat. First of all, we need to add friends or groups. There are many ways to add friends in the confidential message app. We can click the "+" in the upper right corner of the app page, and then add friends through the various icons in the app, or click the "close friend" icon below the app to enter and add close friends. The confidential message can automatically match the list in the phone address book, You can invite the people we want to invite to install confidential messages and then communicate.

The "Secret Message" in the lower left corner of the APP is a received message. After entering, you can see the messages sent by close friends and groups. The Secret Message has a variety of message functions, including blackboard message, ordinary message, security mode message, and ordinary message, which can be viewed directly. However, if the message is encrypted through the secret shield, you must enter the security mode to view it. When the security mode is turned on, the phone screen cannot be intercepted. The dialogue record of the blue shield shown in the figure can only be seen when the security mode is turned on.

Not only message encryption, but also a free network encryption call with a close friend when there is a network. In the security mode, click the "buddy" icon at the bottom of the APP page, click the buddy, enter the buddy information page, click the top secret conversation, and you can have a free encrypted call. For a top secret conversation, both parties need to open the confidential APP and turn on the security mode. If the security mode is not turned on, only ordinary network calls can be made.

summary

MyShield uses the most advanced encryption algorithm, which can encrypt text, pictures, video, voice and other messages, real-time voice calls and other contents. With end-to-end encryption architecture, the middle link of data transmission can not be stolen to ensure personal privacy. External hardware encryption technology completely separates the key from the data. Top secret conversation messages can be scheduled to be destroyed. The chat content is read-only and cannot be copied or forwarded. Screenshots cannot be taken in security mode. After being activated, it supports text, voice, pictures and facial expressions. After reading, it can be destroyed by itself or remotely. Data security is in your control. The Bluetooth connection is fast.

Some disadvantages: because the model I got is a trial model, it has no storage function, and can only use encryption function, so data encryption storage is not available. When turning on and off the LED indicator light of MyShield, people will not know whether it is being turned off or turned on. I don't know whether MyShield is out of power or something. Press and hold the button, and the LED indicator light can't be lit... At present, only encryption function is available, APP LOCK、 The intelligent homing function has not been added. It is recommended to add hardware secret shields of multiple storage capacity versions.
