Fujitsu’s Invisible Cameraphone Hyperlinks

Fujitsu has developed a method for invisibly embedding information into printed images as small as a centimeter square . By printing a series of ( hopefully ) unperceivable yellowed dots into an image , up to 12 digits of numeric data can be conceal , allowing a party to implant a telephone number or encode URL . Then , by taking a picture of the image with a cameraphone or PDA , particular software package can decode the number and call the company ’s telephone act or take care up their webpage . It ’s just in a test copy - of - construct phase at the bit , but if they can jam a few more bit of data , like say a full fictional character set instead of number , it could be a ready to hand applied science .

But if it ’s unseeable , how will anyone know it ’s there ? They ’ll have to make a little logo to show it somehow , and then it ’s not any better than any of the other ocular hyperlinking systems out there .
