Work design improvement at Miroad Rubber Industries Sdn. Bhd.

Erul Food Industries known as Salaiport Industry is a family-owned company and was established on July 2017. Salaiport Industry apparently moved to a new place at Pedas, Negeri Sembilan. Previously, Salaiport Industry operated in-house located at Pagoh, Johor. This small company major business is producing frozen smoked beef, smoked quail, smoke catfish and smoked duck. The main frozen product is smoked beef. The frozen smoked meat produced by Salaiport Industry is depending on customer demands. Usually the company produce 40 kg to 60 kg a day and operated between for four days until five days. Therefore, the company produce approximately around 80 kg to 120 kg per week. The company usually take 2 days for 1 complete cycle for the production as the first day the company will only receive the meat from the supplier and freeze the meat for use of tomorrow

Cover Text Steganography: N-gram and Entropy-based Approach

Steganography is an ancient technique for hiding a secret message within ordinary looking messages or objects (e.g., images), also known as cover messages. Among various techniques, hiding text data in plain text file is a challenging task due to lack of redundant information. This paper proposes two new approaches to embed a secret message in a cover text document. The two approaches are n-gram and entropy metric-based generation of stego text. We provide examples of encoding secret messages in a cover text document followed by an initial evaluation of how well stego texts look close to the plain texts. Furthermore, we also discuss several related work as well as our future work plan

Visual Cryptography and Steganography Methods - Review

In today’s information era information hiding becomes very much important as people transmits the information as innocent as credit card to online stores and as dangerous as terrorist plot to hijackers. The art of information hiding receive attention of the researchers. This paper provides a review of two methods – Visual Cryptography and Steganography for secure communication via a common communication channel. DOI: 10.17762/ijritcc2321-8169.16043

Hybrid Arabic text steganography

An improved method for Arabic text steganography is introduced in this paper. This method hides an Arabic text inside another based on a hybrid approach. Both Kashida and Arabic Diacritics are used to hide the Arabic text inside another text. In this improved method, the secret message is divided into two parts, the first part is to be hidden by the Kashida method, and the second is to be hidden by the Diacritics or Harakat method. For security purposes, we benefitted from the natural existence of Diacritics as a characteristic of Arabic written language, as used to represent vowel sounds. The paper exploits the possibility of hiding data in Fathah diacritic and Kashida punctuation marks, adjusting previously presented schemes that are based on a single method only. Here, the secret message is divided into two parts, the cover text is prepared, and then we apply the Harakat method on the first part. The Kashida method is applied on the second part, and then the two parts are combined. When the hidden ‘StegoText’ is received, a split mechanism is used to recover the original message. The described hybrid Arabic StegoText showed higher capacity and security with promising results compared to other methods

Genetic Algorithm Based Model in Text Steganography

Steganography is an ancient art. It is used for security in open systems. It focuses on hiding secret messages inside a cover medium. The most important property of a cover medium is the amount of data that can be stored inside it without changing its noticeable properties. There are many sophisticated techniques with which to hide, analyze, and recover that hidden information. This paper discusses an exploration in the use of Genetic Algorithm operators on the cover medium. We worked with text as the cover medium with the aim of increasing robustness and capacity of hidden data. Elitism is used for the fitness function. The model presented here is applied on text files, though the idea can also be used on other file types. Our results show this approach satisfied both security and hiding capacity requirements. Furthermore, we found that an increase in the size of the secret message resulted in an exponential increase in the size of the generated cover text. We also found a close relationship between the size of the chromosome used and the population size

A Novel Arabic Text Steganography Method Using Letter Points and Extensions

This paper presents a new steganography approach suitable for Arabic texts. It can be classified under steganography feature coding methods. The approach hides secret information bits within the letters benefiting from their inherited points. To note the specific letters holding secret bits, the scheme considers the two features, the existence of the points in the letters and the redundant Arabic extension character. We use the pointed letters with extension to hold the secret bit ‘one’ and the un-pointed letters with extension to hold ‘zero’. This steganography technique is found attractive to other languages having similar texts to Arabic such as Persian and Urdu.

A Study on Text Based Steganography Using Email Platform and Color Mapping

Steganography is the art of hiding of a message within another so that presence of hidden message is indistinguishable. The key concept behind steganography is that message to be transmitted is not detectable to the casual eye. This is also the advantage of steganography over cryptography. Modern digital steganography uses text, images, audio, video etc. as a cover medium. This paper presents a mechanism of storing the secret message using forward email platform and color mapping table. Various experiments have been conducted and the results are analyzed in this paper
