A lot of techniques are used to protect and hide information from any unauthorized users such as Steganography and Cryptography. Steganography hides a message inside another message without any suspicion, and Cryptography scrambles a message to conceal its contents. This paper uses a new text steganography that is applicable to work with different languages, the approach, based on the Pseudorandom Number Generation (PRNG), embeds the secret message into a generated Random Cover-text. The output (Stego-Text) is compressed to reduce the size. At the receiver side the reverse of these operations must be carried out to get back the original message. Two secret keys (Hiding Key & Extraction Key) for authentication are used at both ends in order to achieve a high level of security. The model has been applied to different message languages and both encrypted and unencrypted messages. The experimental results show the model’s capacity and the similarity test values.

  • This paper uses a new text steganography that is applicable to work with different languages
  • The Model produce random text characters called Cover-text to hide the message randomly
  • The model capacity and similarity are tested using Arabic and English text files
  • The purpose of this study is to conceal the sensitive information from an unauthorized use.
