A photograph is an effective form of communication and sharing as “A picture is worth a thousand words”. PhotoViz is a freeware with a set of innovative tools that extends the traditional uses of images. PhotoViz consists of a set of tools to automatically fix basic problems in photos, read secret messages, access content or view photo galleries embedded in images. All images can be viewed by any available image viewer software but nobody knows that the image contains hidden content. They looked just like any other images and with no loss in image quality. PhotoViz provides security and secrecy by ensuring that only the targeted audience can retrieve the contents in the image.
The functional overview of PhotoViz is shown at Figure
1.1. PhotoViz functions are broadly
divided into three categories: Image Correction, Content Access Control (
The Content Access Control Module encrypts
digital content into images and can restrict access to the embedded content
through the use of passwords or registration images. Registration Photos are
special images that must first be viewed before users can access content in
subsequent images. The

Active Photo is a novel way of delivering content, web applications quickly and easily through the use of images. Active Photo offers an easier, more intuitive way to view, manage, and share your photos. Currently, there are two implementations of Active Photo: iphone Active Photo (or @Photo) and Active Gallery. @Photo is an iPhone app that enables users to embed media such as messages, location data and audio files into photos (see Figure 1.2a). Photos from the iphone can shared and sent via email. Embedded media, location and the phone’s parameters can be accessed by PhotoViz. A free Lite version and a paid version of @Photo is available in Apple’s iTunes App Store. More information about @Photo can be found at www.picsalive.com/ap.
Active Gallery enables users to create their own Photo Galleries and embed them into a single image. Viewers can also view a slide show, rate and add comments to the photo gallery. Active Galleries are created at the online OOOID portal (www.oooid.com) and can be viewed in PhotoViz. An Active Gallery on the Singapore Flyer is shown on Figure 1.2b. The Active Gallery can be viewed by in blogs or users’ websites by inserting a few lines of codes. Photos in Active Gallery are secure and can be shared online or offline with friends and family.
