COMPUTER FORENSICS By : Ch. Rekha Priyanka (08Q61A0515)
Introduction: ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]
HISTORY OF COMPUTER FORENSICS : ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]
WORKING PROCESS : Methods of hiding Data : To human eyes, data usually contains known forms, like images, e-mail, sounds, and text. Most Internet data naturally includes gratuitous headers, too. These are media exploited using new controversial logical encodings: Steganography and marking. ,[object Object],[object Object]
[object Object],WORKING PROCESS : Method of Hiding Data ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]
Methods Of Detecting/Recovering Data : ,[object Object],Steganalysis Methods - Detection ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]
Methods Of Detecting/Recovering Data : Steganalysis Methods – Recovery – Recovery of watermarked data is extremely hard. • Currently, there are very few methods to recover hidden, encrypted data. – Data hidden on disk is much easier to find. Once found, if unencrypted, it is already recovered – Deleted data can be reconstructed (even on hard drives that have been magnetically wiped) – Check swap files for passwords and encryption keys which are stored in the clear (unencrypted) – Software Tools • Scan for and reconstruct deleted data • Break encryption • Destroy hidden information (overwrite)

CONCLUSION : With computers becoming more and more involved in our everyday lives, both professionally and socially, there is a need for computer forensics. This field will enable crucial electronic evidence to be found, whether it was lost, deleted, damaged, or hidden, and used to prosecute individuals that believe they have successfully beaten the system.

Once found, if unencrypted, it is already recovered – Deleted data can be reconstructed (even on hard drives that have been magnetically wiped) – Check swap files for passwords and encryption keys which are stored in the clear (unencrypted) – Software Tools • Scan for and reconstruct deleted data • Break encryption • Destroy hidden information (overwrite)
