What are data hiding techniques?
Cryptography and steganography are two techniques commonly used to secure and safely transmit digital data.
In cryptography we are trying to make our message scrambled and unread; in steganography we are trying to hide the existence of the message by concealing it inside another unsuspicious message..
What is data hiding in digital forensics?
Data hiding. Data hiding is the process of making data difficult to find while also keeping it accessible for future use. “Obfuscation and encryption of data give an adversary the ability to limit identification and collection of evidence by investigators while allowing access and use to themselves.”
How do you use steganography tools?
Image Steganography You can hide text messages or files inside an image file. Just select the source file in which you want to hide the secret message and then select the file to hide or write the text message to hide. Select the output image location and then click on the start button to start encoding the file.
How do you detect steganography?
By looking at repetitive patterns, you can detect hidden information in stego images. These repetitive patterns might reveal the identification or signature of a steganography tool or hidden information. Even small distortions can reveal the existence of hidden information.
How do you make a secret message?
Writing Secret Messages Using CiphersWrite out the entire alphabet in a line.Choose a number to be your “rotation” amount. … Under your first line, starting at the letter you “rotated” to, rewrite the alphabet. … Decide what your message is going to say and write it on a piece of paper. … To decode a message, you do the process in reverse.More items…•
How can you hide data by marking bad clusters and using bit shifting?
To mark a good cluster as bad using Norton Disk Edit, we type the letter B in the FAT entry corresponding to that cluster. We can then use any DOS disk editor to write and read data to this cluster, which is effectively hidden because it appears as bad to the OS.
What is data hiding and data encapsulation?
Data encapsulation, also known as data hiding, is the mechanism whereby the implementation details of a class are kept hidden from the user. The user can only perform a restricted set of operations on the hidden members of the class by executing special functions commonly called methods.
What are the cryptographic techniques?
The process of confidentiality, integrity, and authentication, is also known as CIA. Cryptographic techniques include encryption, which involves applying a procedure called an algorithm to plain text to turn it into something that will appear to be gibberish to anyone who doesn’t have the key to decrypt it.
What is the difference between data abstraction and data encapsulation?
Abstraction is the method of hiding the unwanted information. Whereas encapsulation is a method to hide the data in a single entity or unit along with a method to protect information from outside. 4. … Whereas encapsulation can be implemented using by access modifier i.e. private, protected and public.
What is anti forensics in cyber security?
Essentially, anti-forensics refers to any technique, gadget or software designed to hamper a computer investigation. There are dozens of ways people can hide information. Some programs can fool computers by changing the information in files’ headers.
Is Steganography still used?
Is Steganography still used? Yes, Steganography is still popular among cyber criminals. Recent attacks show that security researchers found a new malware campaign that used WAV audio files to hide their malware. It is believed that the attackers used Steganography to embed the malicious code inside the WAV audio file.
What makes steganography unique?
Encryption is much simpler and far more data can be encoded in the same space. With techniques such as public-key encryption, you can even communicate without a secure channel. When steganography is used by itself, it’s security through obscurity, which can lead to the secret message being revealed.
What is the difference between data hiding and data abstraction?
Abstraction and Data hiding are the crucial concepts of the object-oriented programming. Abstraction is a method of expressing the important properties without involving the background details. On the other hand, Data hiding insulates the data from the straight access by the program.
What is a forensic countermeasure?
“Countermeasure” means an action, an incident, or a process that prevent the normal forensic protocols. … It threatens the integrity of the forensic works. Take an outdoor crime scene as an example.
Which of the following is the definition of anti forensics?
The process of acquiring and analyzing information stored on physical storage media, such as computer hard drives or smartphones is the definition of anti-forensics. … Computer forensics is the exclusive domain of law enforcement.
What can steganography be used for?
Steganography is the art of hiding a message. The purpose of steganography is to hide a message from a someone you don’t want to see it. … Steganography works by changing bits of useless or bot used data in regular computer files (such as graphics, sound, text, HTML) with bits of different, invisible information.
What is steganography techniques?
Steganography is the technique of hiding secret data within an ordinary, non-secret, file or message in order to avoid detection; the secret data is then extracted at its destination. The use of steganography can be combined with encryption as an extra step for hiding or protecting data.
Which Oops talks about data hiding?
Data hiding is a software development technique specifically used in object-oriented programming (OOP) to hide internal object details (data members). Data hiding ensures exclusive data access to class members and protects object integrity by preventing unintended or intended changes.
