![]() Some apps, especially those used for communication place a special emphasis on security and safety around messages and media by encrypting this information as it is sent between users. It’s worth noting that experts don’t think you should do this – encrypting only one or two files on a phone signals to a would-be cybercriminal that those particular files are of interest and worth paying special attention to.Īpp encryption, then, falls on app developers. ![]() You could protect one or more individual files by encrypting them in a secure folder (a default feature on many phones) or by installing an app to do the job. In most practical senses, apps and files are quite distinct. It would prevent, for example, somebody accessing your data if your phone was lost or stolen and protected with the encryption PIN or password.Īpp or file encryption protects a subset of the information on your phone, but not all of it. Whole-phone encryption means that all the data contained on a device is protected from unauthorised access. Where can encryption be used?įor most users, the concept of encryption will show up in the following three areas: Luckily, most developers, phone makers, and operating systems are built such that effective encryption is within everyone’s reach. If for some reason it isn’t, or you choose not to use the built-in encryption, you can also rely on a variety of third-party apps to provide it for you. On mobile devices, whole-phone encryption is generally enabled by default on modern handsets and operating systems. ![]() The only way of turning it back into understandable text (or code) is by supplying a key or password. In simple terms, it turns information into a secret code that will look like gibberish to anyone who sees it. What is device encryption and why should you use it?Įncryption is a security measure designed to protect sensitive information from prying eyes.
