An article in The New York Times (@NYTimes) describes the solution for authors who want to sign their book on someone’s ereader. Autography LLC is a media technology firm in St Petersburg, Florida with a patent-pending method for inserting an autograph or other salutation into an ebook. This personalization can take place at the time of purchase or any time afterwards.
Here’s how an Autography eBook “signing” will work: a reader poses with the author for a photograph, which can be taken with an iPad camera or an external camera. The image immediately appears on the author’s iPad (if it’s shot with an external camera, it’s sent to the iPad via Bluetooth). Then the author uses a stylus to scrawl a digital message below the photo. When finished, the author taps a button on the iPad that sends the fan an email with a link to the image, which can then be downloaded into the ebook....
[W]ithin the year consumers should expect to see a variety of advances in digital signing, including ebooks that are sold with blank pages for that purpose. Some devices already have their own solutions, like Sony’s Reader, which enables authors to use a stylus to sign a page on its screen.
