Abstract:
When it comes to preventing unauthorised access to, destruction of, or inspection of confidential data, information security has always been a major factor. Multimedia information is now used in every field throughout the world. The confidential information that is used in these areas must be kept secure. There are a variety of methods for keeping data secure. One of these is steganography, which is concealing information within other data into a format that the cover information remains unchanged. Cryptography, an encryption process that scrambles data into a written form that is sometimes re

Abstract:
The storage or circulation of secret messages is vulnerable to being accessed or wiretapped by parties who do not have legal authority. Therefore, to avoid this and also to secure a secret message known an encryption process called cryptography. In order for the message to be kept confidential, the message is inserted into the image object. Inserting a message in an image or more commonly known as steganography is the development of previously known cryptographic methods. The method with steganography can be said to be better than the previous cryptography. To secure secret messages from unaut

Abstract:
Cryptography is both a science and an art to keep the message confidential. While steganography is the science and art of hiding secret messages in other messages so that the existence of such secret messages is unknowable and generally serves to disguise the existence of confidential data making it difficult to detect and protect the copyright of a product. Steganography requires two properties, namely container media and secret messages. The application of steganographic and cryptographic combination is done by Least Significant Bit (LSB) and ROT13 algorithm. Steganography with the LSB metho

Cryptography is the art of coding and decoding the communication. Cryptography ensures the security of delicate information over some confidentiality breaching resources. In the recent age Cryptography has turned into a battleground of some of the world’s best mathematicians and computer scientists. A number of transforms like Sumudu transform, Laplace transform, Fourier transform, Kamal transform, Mellin transform, Jafari transform, Aboodh transform, N-transform, ELzaki transform, MAHGOUB transform are frequently used in cryptography.

The entry of mankind into the era of high technologies, the rapid growth of computer technology contributes to the expansion of the range of electronic services. To ensure the security of confidential information, personal data, cryptographic systems of traditional cryptography (symmetric cryptosystems) and public key cryptography (asymmetric cryptosystems) are used. As a rule, the former provides security services, the latter provide key distribution.

Abstract:
Humans interact with fellow humans using communication. Not everything that is communicated contains a message so that it can be known by many people, sometimes the communication is confidential so that only certain people can know it. The occurrence of data tapping submitted is certainly a problem if the data is confidential, therefore a data security system is needed so that the data cannot be stolen or changed by tappers or crackers. One solution to secure data is to use cryptography. Cryptography is the science and art of maintaining message security when messages are sent from one media t

We introduce a general concept of multidivisible online/offline (MDO) cryptography, which covers the previous works including online/offline cryptographic schemes, divisible online/offline signatures, incrementally executable signcryptions, and multidivisible online/offline encryptions. We then present the notion of multidivisible online/offline signcryptions (MDOSCs) as novel application of MDO cryptography. We define several security notions for MDOSCs and show implications and separations between these security notions. We also present a generic construction of MDOSC that achieves the stron

Cryptography is important in securing data and information. Confidential, important information may not be publicly or otherwise protected. It is not impossible for anyone to see, damage, steal or misuse important data from an agency or company through a computer network. The solution is with cryptography or a method of data security that can maintain the confidentiality and authenticity of a data or information.

It plays an important role in accessing the trustworthiness of the object, verifying its reliability and conducting audit trails of its lineage. Digital provenance forms an immutable directed acyclic graph (DAG) structure.
