Abstract

Security is an important aspect in digital data transmission, and steganography is one way for hiding a secret message in such a way so that others are not aware of the existence of something in the message. In this research, we built a digital steganography system using web-based with Adaptive Minimum - Error Least Significant Bit Replacement (AMELSBR) method. The media to hide the message is on the form of .jpg, the output is on the form of .png, and the message is on the form of .txt. The procedures for applying AMELSBR method are Capacity Evaluation, Minimum - Error Replacement and Error Diffusion. The result shows that the AMELSBR method is able to manage for hiding and restoring files without causing excessive distortion (noise) in stego image. The AMELSBR method has a possibility of returning most files to image manipulation such as the change of image Brightness and Contrast with the black color dominant (rgb(0,0,0)), white color dominant (rgb(255,255,255)).

Abstract

Security and confidentiality of data transmission are two important aspects in the era of openness to data access and information. One way to secure the data transmission is using steganography. In this research, the method used is End Of File (EOF) and used image as the medium. The message is hidden by inserting it in the end of the line image file. The media for hiding the message is in the form of .jpg and the output is in the form of .png. Inputting message is done manually. Testing have  been conducted on 5 types of images with different resolutions with a number of different messages characters which are 10, 100, and 1000 characters. The results show that the method of End Of File (EOF) successfully used to hide message in the media image and to take back the message that has been inserted. The image size and the number of characters used affects the processing time for embedding and extracting. Cropping, contrasting, and brightness on stego image are conducted to analyze the resilience of the message inserted. The results show that the stego image manipulations are sensitive or resistant to the manipulation that makes the message becomes corrupted and are not recommended in manipulating stego image.Keywords : embed, End Of File (EOF), extract, image, steganography, stego Image

Abstract

This study developed a Decision Support System (DSS) by utilizing Analytical Hierarchy Process (AHP) Method as a process in selection of employees acquisition. This selection process used several criteria (multicriteria) to choose which applicants will be accepted. This Decision Support System (DSS) helps managers of Human Resources (HR) in deciding which applicants will be selected. In this application, there are criteria used and the weight of those criteria. This application of module business process will be able to generate the rank of each applicant based on the final amount. The applicant who has the greatest value will be given a better rank and it means that the applicant has criteria in accordance with company’s requirement. In addition, Web Service as a business process of payroll modules. In this process, a set of functions or methods which contained on a server can exchange data and information using an operating system and application that different from each other through the internet that uses XML as the format of message delivery. This system constructed by using PHP and MySQL as language. The result of functional testing data based on test case testing shows that the system can work "in accordance" with its analysis.

Abstract

The security is the most important thing in sending a secret message and there are many ways to send a message safely, one of those is steganography. In this research we will compare Dynamic Cell  Spreading (DCS) and Spread Spectrum method based on web application using image as the media and hide the secret message. The file format used are (.jpg) as input cover,(.png) as output stegoimage, and  (.txt) as data that can be inserted. Doing some test to manipulate brightness, contrast, and cropping the results show that Spread Spectrum method better than Dynamic Cell Spreading method. The Spread Spectrum method mostly returns the message in the brightness and contrast manipulation. Cropping stegoimage on the right area or bottom image has less risk of losing data depend on the cropping scale and image resolution.
