What is cryptography how is it useful?
Cryptography is an information security tactic used to protect enterprise information and communication from cyber threats through the use of codes. Cryptography achieves several information security-related objectives including confidentiality, integrity, and authentication, and non-repudiation.
Why do we need visual cryptography?
In way that encrypted image can be decrypted by the human vision if the correct image key is used. By this cryptographic technique we can encrypt visual information (pictures, text, etc.) in a way that human visual system can perform decryption of encrypted information & no aid of computers needed.
What is the importance of cryptography in e commerce?
The importance of cryptography is that, it can protect e-Commerce and reassure businesses and consumers that they are safe and secure from prying eyes (hackers who utilize the Web to steal information). The use of cryptography allows the integrity of e-Commerce transactions and can safeguard information.
Where is visual cryptography used?
Visual Cryptography is a wide area of research used in data hiding, securing images, color imaging, multimedia and other such fields. Visual Cryptography comes in the field of data hiding used in cybercrime, file formats etc.
Why do we need cloud cryptography?
Cryptography in the cloud protects sensitive data without delaying information exchange. Cryptography in the cloud allows for securing critical data beyond your corporate IT environment, where that data is no longer under your control.
How is cryptography used in social media?
Cryptography helps securing the data storage and transmission with the goal that only intended user can see it. It keeps the data completely hidden from the third party who is actually present at the same time.
How is cryptography used in business?
Encrypted data represents an insurmountable challenge from which they cannot profit. Such use of encryption to protect your data and keep it from being used by perpetrators is a prime example of using cryptography for business.

Without the detection of any suspicious activity, the data cannot be altered in storage or transit with respect to the sender and the intended receiver. Prominent Non-Repudiation.
What are the objectives of cryptography?
C-Confidentiality: Ensuring the information exchanged between two parties is confidential between them and is not visible to anyone else.
What is the role of cryptography in information security?
Cryptography protects the confidentiality of information. Confidentiality is a key priority when it comes to cryptography.
How is cryptography used in everyday life?
p. 1259. Cryptography in everyday life. Abstract. ‘Cryptography in everyday life’ contains a range of situations where the use of cryptography facilitates the provision of a secure service: cash withdrawal from an ATM, Pay TV, email and file storage using Pretty Good Privacy (PGP) freeware, secure web browsing, and use of a GSM mobile phone.
