Protecting information and sources has been fundamental since the beginning of journalism, but the use of technology has made reporters have to look for new methods.
At the digital level, protecting the contents that we have in the cell phone (conversations, notes, photos, videos, contacts ...) is fundamental. Therefore, more and more journalists are looking for tools that allow them to encrypt these contents.
In the market there are too many applications that allow you to do this process. However, it is essential to take into account two key aspects when selecting any tool.
1.End-to-End Encryption: This means that only users who are communicating can read the messages they are exchanging. This prevents even telecommunications providers or the same App from having access to the content.
2. Anonymous Messaging: This feature implies that those who provide the communication service do not know who the interlocutors are, as they keep them anonymous.
The most recommended application by experts to protect this content is Signal Private Messaging, which works just like any other messaging application but ensures end-to-end encryption and anonymity. The application is also available for IOS.
Whatsapp is also profiled as a useful application, as it ensures the encryption of the information but not the privacy of the same, there is no anonymity. However, in countries with oppressive regimes like Sudan, using other applications would raise suspicions. This makes it better to use Whatsapp despite the privacy risks.
However, other widely-recommended applications, such as Telegram, are no longer seen as reliable tools since it was discovered that they store their information on non-encrypted servers, making it easily traceable.
