Hermetic Systems releases two new products: A tool for HTML table creation and software to hide data in PNG images

Hermetic Systems has released two new programs of interest to people who write their own web pages using tables and PNG images.

HTML Table Creator Tool: There are online table generators which generate code for simple HTML tables, but these are not adequate for creating complex tables with various cell sizes and contents. ‘HTML Table Creator Tool’ is an interactive TABLE generator which handles COLSPAN and ROWSPAN, thus enabling creation of complex tables with cells larger than 1 row by 1 column. Individual cell specifications can include cell content (which can itself include HTML code), font name, font size, color, alignment, etc. A cell specification can be copied to other cells, or all cells in a row or column, thus allowing rapid development of tables. Table specifications can be saved and later loaded for re-use. The user manual includes four mini-tutorials which demonstrate graphically the use of the program.

Stego PNG: This is an easy-to-use steganography program which allows you to hide a file of any type (text, image, spreadsheet, etc.) in a PNG image file (with the use of an encryption key), so that the appearance of the image is unchanged and the presence of the hidden file is undetectable. The hidden file can be extracted only by someone who knows the key used to hide it. This is useful for hiding a copyright notice (or a message) in a PNG image on a web page. For example, suppose you have taken a lot of great photos and uploaded them (as PNG files) to some website which is viewed by many people. If you wish to add a copyright to an image, but don’t wish to add visible text to the image then you can add a ‘watermark’ in the sense of hiding a copyright notice within the image. If you later find your photo has been used by someone on some web page without your permission then you can download the image and verify that your copyright notice can be extracted from the file, then you can inform the unauthorized user of this. Your copyright notice can also be in the form of an image file. Further information is available at: http://www.hermetic.ch/stpng/stpng.htm
