In today’s digital age, photos are an integral part of our lives. We capture and store countless memories on our smartphones, computers, and other devices. However, with the rise of digital storage, concerns about data security and recovery have also increased. One question that often arises is whether permanently deleted photos can be recovered by the police. In this article, we will delve into the world of digital forensics and explore the possibilities of recovering deleted photos.
Understanding Digital Storage And Deletion
Before we dive into the recovery process, it’s essential to understand how digital storage works and what happens when we delete a file. When you take a photo with your smartphone or camera, it is stored on the device’s memory card or internal storage. The photo is made up of a series of 1s and 0s, which are written to the storage device.
When you delete a photo, it’s not immediately erased from the device. Instead, the operating system marks the space occupied by the photo as available for new data. This process is called “logical deletion.” The actual data remains on the device until it’s overwritten by new information.
Types Of Deletion
There are two types of deletion: logical deletion and physical deletion.
- Logical Deletion: As mentioned earlier, logical deletion occurs when the operating system marks the space occupied by a file as available for new data. The actual data remains on the device until it’s overwritten.
- Physical Deletion: Physical deletion, on the other hand, involves the actual destruction of the data. This can occur when a device is physically damaged, such as when a hard drive is crushed or a memory card is burned.
Can The Police Recover Permanently Deleted Photos?
