Everyone has a secret in the phone that you would not like exposed. It could be a photo, message, file, link, or anything that would compromise your position. When you want to give away the handset or sell it, such information needs to be cleared to prevent it from falling into unsafe hands. Cell phone forensics experts have recommended ways you can protect information from compromise.
Use the factory reset option. This is the first resort for most people and devices. It is meant to clear all information and settings that have been altered since the handset began to be used. Some phones work by locking handsets from setting alteration. This might not work if you are selling or giving it since it will be useless to the receiver. However, it still provides a reasonable deal of information protection.
Resetting factory settings does not wipe out data. It only locks it in a place that is irretrievable through your handset. With advancement in technology, such information may be retrieved with ease. If someone employs off-the-shelf techniques and technology, your secret information will be retrieved leading to compromise. You therefore need more advanced ways of concealing the information and erasing it completely from the system.
Data encrypting is another option. This is an option that is limited to certain handset models which means that it is exposed to limited use. It means that anyone trying to access information from that handset will have to provide an unlocking key. Since you will be the sole holder of the key, your information will be protected.
There are inbuilt capabilities to encrypt data. However, there are software that allow encrypting of information as an added feature. This means that you have to download such applications. Even these options do not guarantee safety because applications and systems have been hacked despite appearing secure. While some encrypt by default, you will need to activate such options for some phones.
Overwriting the existing data is also an option. The phone provides this option when you are about to save files. This creates more space for new files that need to be saved. It is also a way of damaging the existing data. This approach will allow you to skip the deleting element and head straight to saving data. It will still be possible for someone to retrieve information using advanced software despite overwriting.
External memory devices like SIM cards and SD cards should be removed. They are storage devices which hold files and information that you may consider confidential. Once you remove them from the phone, all the information that was stored in them disappears and cannot be accessed by the phones again. It can only be accessed once the cards are returned. This option will only work if you had chosen external storage for your data.
Data recovery technology has made it almost impossible to permanently delete information from phones. However, since recovery relies on advanced technology, it is still possible to conceal files and data from unauthorized persons. Follow the directions of your handset to guarantee security. If you would not want any information to fall into the public eye, do not generate it in the first place.
