A Fundamental Study on Digital Video Watermarking for Two-Dimensional Barcodes Displayed on Mobile Phone Screens

Two-dimensional barcodes (2D codes) have become common as an authentification way of e-tickets and e-coupons. However, easy replication by using other mobile phone camera is apprehended. This paper proposes a method for detecting copied 2D code by a semi-fragile digital video watermark which can be destroyed by replication. Compared to digital image watermarking, it is more difficult to copy 2D...

Effects of Aging and Display Contrast on the Legibility of Characters on Mobile Phone Screens

Nowadays, mobile phones are very popular in the world. The use of text email with short message service (SMS) is spreading. In this study, we evaluated the legibility of characters on the liquid crystal displays of mobile phones. When characters are small, younger people assure readability by shortening the viewing distance. However, elderly people find it far more difficult to see small charac...
