Using Facebook for Image Steganography
Because Facebook is available on hundreds of millions of desktop and mobile
computing platforms around the world and because it is available on many
different kinds of platforms (from desktops and laptops running Windows, Unix,
or OS X to hand held devices running iOS, Android, or Windows Phone), it would
seem to be the perfect place to conduct steganography. On Facebook, information
hidden in image files will be further obscured within the millions of pictures
and other images posted and transmitted daily. Facebook is known to alter and
compress uploaded images so they use minimum space and bandwidth when displayed
on Facebook pages. The compression process generally disrupts attempts to use
Facebook for image steganography. This paper explores a method to minimize the
disruption so JPEG images can be used as steganography carriers on Facebook.Comment: 6 pages, 4 figures, 2 tables. Accepted to Fourth International

A Computer-Based Method to Improve the Spelling of Children with Dyslexia
In this paper we present a method which aims to improve the spelling of
children with dyslexia through playful and targeted exercises. In contrast to
previous approaches, our method does not use correct words or positive examples
to follow, but presents the child a misspelled word as an exercise to solve. We
created these training exercises on the basis of the linguistic knowledge
extracted from the errors found in texts written by children with dyslexia. To
test the effectiveness of this method in Spanish, we integrated the exercises
in a game for iPad, DysEggxia (Piruletras in Spanish), and carried out a
within-subject experiment. During eight weeks, 48 children played either
DysEggxia or Word Search, which is another word game. We conducted tests and
questionnaires at the beginning of the study, after four weeks when the games
were switched, and at the end of the study. The children who played DysEggxia
for four weeks in a row had significantly less writing errors in the tests that
after playing Word Search for the same time. This provides evidence that
error-based exercises presented in a tablet help children with dyslexia improve
their spelling skills.Comment: 8 pages, ASSETS'14, October 20-22, 2014, Rochester, NY, US
Towards a user-friendly webservice architecture for statistical machine translation in the PANACEA project
This paper presents a webservice architecture for Statistical Machine Translation aimed at non-technical users. A workďŹow editor allows a user to combine different
webservices using a graphical user interface. In the current state of this project, the webservices have been implemented
for a range of sentential and sub-sentential aligners. The advantage of a common interface and a common data format allows the user to build workďŹows exchanging different aligners
