You may not have heard of the Signal app, but its user experience is similar to many other video calling and chat apps you may have used in the past. In recent years, Signal has become the tool of choice for journalists and others who want to ensure the privacy of their communications.
There are more choices for chat apps than before on the mobile phone, so it is very important to pay attention to privacy.
If you are currently involved in activism or journalism or other sensitive areas, now is the right time to start switching to encrypted communication. Even if you are away, it may be the case with people you know.
It is a good thing to let them choose to keep their communications secure with you. In addition to using interesting tags in conversations, it won’t cost you anything, and in future work, it may prove to be very valuable because it prevents you from spying on advertisers or restricting government investigations. More and more blurred.
End-to-end encryption sounds like a technical buzzword, but this is an important differentiating factor when choosing a messaging service. Essentially, it ensures that only the sender and receiver (the “end” of the conversation) can see the content of the message you send.
Even if other parties (such as technology companies, Internet service providers, or hackers) capture or observe the message data, the message data will be displayed in the code that they will not be able to read.
Signal uses this end-to-end encryption in all forms of communication. Facebook’s WhatsApp and Apple’s iMessage also use it. For example, other chat applications (such as Facebook Messenger) are not end-to-end encrypted, and there is no standard SMS text.
A week ago, the socially estranged dear Zoom announced that it will not make encrypted toll-free calls, specifically designed to provide law enforcement access if people “abuse” the platform.
The company claims that it will not actively monitor or record the call, but will investigate whether the host reports bad behavior. You may recall that Zoom in March originally claimed that it was “end-to-end” encrypted, and then had to give up its promise due to the public’s counterattack.
Even if an application that does provide end-to-end encryption promises, there will still be some data collection on both ends. For example, WhatsApp cannot access the content of your calls or messages but can track other information about your callers, contact frequency, and communication duration.
The security of this information is not as secure as applications such as Signal. In addition, the fact that WhatsApp is owned by Facebook is enough to suspend security-conscious users.
Although Facebook announced plans to end-to-end encrypt all of its messaging services, it faces huge legal hurdles. The US government expressed dissatisfaction with the plan. At last year’s congressional hearing, Senator Lindsay Graham requested a back door for the company’s messaging service. He threatened: “You will find a way, otherwise we will do this for you. “So far, Facebook has been persistent, but it is under pressure.
What are the benefits of Signal?
The selling point of the application starts with the code itself. Signal uses open source development, so anyone with expertise can dig into the program and see how it works to ensure that there are no secret holes or traps inside to devour personal information.
It can also be used on Android, iOS, and desktop computers, so it is compatible with most popular devices in the world. Apps like Apple’s iMessage can’t compete with it.
Unlike other social media communication applications, Signal does not establish a contact list in its own system, nor does it have to store contact data on its servers.
At the end of last year, Signal announced that it was developing a system called “safe value recovery” that would allow users to keep their contact lists between devices without having to store a plain text copy of your contacts in the cloud, Because the cloud stores more content.
