Dialect Cryptography

Postcards document the natural landscape as well as the built environment—buildings, gardens, parks, cemeteries, and tourist sites. It has strong regional characteristics. With the development of mobile phones and other electronic products, people travel more likely to send digital photos for each other, and fewer and fewer people are writing postcards. I design a series of postcard for my hometown, Sichuan Province in China. Adding the fun and interactive function to the ordinary traditional postcard. In my work, Sichuan dialect (Sichuan dialect is a language with strong regional characteristics) , panda and mahjong as the design element combine with Visual Cryptography (Visual cryptography is a technique that overlaying both pictures exactly on top of one another, will reveal the hidden information). The postcard can be divided into 2 layers. We can send a postcard(layer1) by mail, and send another layer as digital file through mobile phones. When we receive 2 layers, we can overlap them, and find the “real message”. This is a good way to combine traditional postcard and digital tools.
