Different Methods of Shredding
When an IC chip storing unnecessary private information is connected with a printing paper, a shredder applies voltage to the IC chip by a discharging unit to obliterate the IC chip and to make it unfeasible to read the furtive information there from. After that a shredding cutter cuts the printing paper and the shredded printing paper is discarded. A shredding equipment includes a convey path that transports an image through the shredding machinery and a sensing unit that senses as to whether the paper going into the shredding machine has an electronic data storage device connected to it. Along the convey path a data destroying process unit wipes out electronic data stored in the electronic data storage appliance as the paper passes thereby along the transport path. A control unit that controls the data demolition process unit to obliterate the electronic data stored in the electronic data storage device of inserted paper if the sensing unit feels that the inserted paper has the electronic data storage device connected to it and a shredding process unit, provided along the same conveying path that shreds the entered paper.
There are a number of various methods of shredding for the different media on which the data is stored. These shredding methods have been detailed below.
Paper Records Shredding:
The security given by the destruction of records depends on how well the paper is shredded. Cross shredding may be required for mostly perceptive documents. Shredded paper may be pulped and recycled, or may be used for filling or other purposes.
Pulping:
Pulped paper is condensed to its element fibers. If carried out properly, it is a very safe method of shredding. Pulped paper is normally recycled.
Burning:
Papers should only be burnt if there is no environmental friendly method of shredding obtainable. Records should be burned in accordance with any ecological rules and local burning limitations. Tightly packed paper does not burn well, so burning should be done in an industrial place (not in a ‘backyard’ incinerator).
Burying:
Burying is not a suitable method of destruction. The records are not destroyed right away and may take months or even years to break down. Documents that are buried may also be exposed within hours or days of being buried.
Electronic/magnetic media
Magnetic Media:
Information stored on magnetic media can be "bulk erased" by subjecting them to a strong magnetic field. For safe demolition magnetic media can be reformatted. Backup copies of the information also have to be ruined. The media can then be reused. Just deleting does not eradicate data from magnetic media and is therefore not adequate for the obliteration of records.
Optical Media:
Information stored on optical media can be destroyed by cutting, crushing, or by other physical means of shredding. Re-writable optical disks must be reformatted before being shredded or re-used.
Hard drives:
Hard drives of the computers and servers must be reformatted before computers are disposed of. Do not just delete files from electronic media such as floppy disks, re-writable optical disks and hard disks, as the information can be retrieved.
Non-Electronic and non-paper media:
Videos, cinematographic film and microforms (microfilm/ fiche/ aperture cards/ x-rays) can be ruined by shredding, cutting, crushing or chemical recycling.
