The rapid growth of online communication has increased the demand for secure communication. Most government entities, healthcare providers, legal sector, financial and banking, other industries are vulnerable to information security issues. Text steganography is one way protect by hiding secret messages in cover text. Hiding a high amount without raising attacker’s suspicion main challen...

A novel method of natural language information hiding is presented based on Chinese mathematical expression. The method can convert Chinese text into bit string by using the thought of Chinese mathematical expression, and then embed the secret message into the text by utilizing the replacement of synonyms, variant forms of the same word, the adding or deleting of the empty words, and the shift ...

The management of unstructured data is recognized as one of the major unsolved problems in the information industry and data mining paradigm. Unstructured data in computerized information that either does not have a data model and there are not easily usable by data mining. This paper proposes a solution to this problem by managing unstructured data in to structured data using legacy system and...

In this paper we survey different steganography techniques for encrypting the data along with characteristics, difference with cryptography. Steganography is the art and science of hiding information by embedding messages within other, seemingly harmless messages. Steganography works by replacing bits of useless or unused data in regular computer files (such as graphics, sound, text, HTML, or e...

In this paper, we consider the problem of authentication of biometric identification documents via mobile devices such as mobile phones or PDAs. We assume that the biometric identification document holds biometric data (e.g., face or fingerprint) in the form of an image and personal data in the form of text, both being printed directly onto the identification document. The proposed solution mak...

Steganography is one of the methods of secret communication that hides the existence of hidden message. It can be defined as the study of invisible communication that usually deals with the ways of hiding the existence of the communicated message. The hidden message may be text, image, audio, video, etc. The files can be a cover image after inserting the message into the cover image using a ste...
