How to delete your data permanently

Whenever you can have a view at the ‘delete’ option of the operating system you know that the data has been moved to recycle bin and you can restore your file any time from there. But, when suppose you want to permanently delete the files you have to use the ‘shift + delete’ keys together of the windows.

            When the files are deleted using the ‘delete’ or rather ‘shift + delete’ option, the relevant data of the file is not deleted, only the pointer to the file is deleted. While doing this, the file is marked as deleted and the space used by the data is marked as free. When a fresh folder or file is saved in the memory, it overwrites the data content of the deleted file. This makes the previous data lost. Some of the data that was not overwritten can still be recovered. This data area may be containing confidential information, and if this confidential information goes into hands of others, it can be misused.

To delete data, we’ve to fill the bits that have significance with bit outline that has no inbuilt meaning. The same method is followed by data wiping applications. They overwrite the data with arbitrary bit patterns. These bit patterns are generated through algorithms applied by help of the records eraser programs. 

          There are lots of overwriting algorithms that may create various bit patterns of 0s and 1s. The simplest data wiping algorithm overwrites all the data with 0s. The overwriting of bits is done multiple times according to the allowed standards. Governments of nearly all the nations have abided the companies to adhere to data wiping standards.
