A Chrome Extension to Hide Messages in Photos on Facebook

Facebook is the last site you will trust your secrets with. Things are changing now. Owen Campbell-Moore, the Oxford University student of computer science at Oxford University came up with a special methodology for encryption of secret messages in the photos of Facebook. This new method designed by Moore has been named Secretbook. This is an extension of Google Chrome that takes the help of JPEG Steganography for encoding data in the photos through making almost imperceptible changes in the images. The messages are not hidden in its pixels but, in the image’s digital make-up. The encryption process can be compared to digital invisible ink.

According to Moore, Steganography is simply instrumental in hiding messages under a cover made of images or data. This is a novel idea that has not yet been applied to messages of social networking sites. Moore and his professor Mr. Andrew Ker found this to be the best possible way to protect details that are not intended to be disclosed to everyone. Millions of images are shared on social networking sites everyday. So, this could be the best tool at hand to hide what you wanted to hide from the pages exposed to many users of these much publicized sites.

How to Hide Your Message?

You, along with your recipient have to download a special extension and press ‘Alt- Control-A’ on the page of Facebook for getting the app activated. You need to upload an image and eventually a pop-up will tell you how many characters the photo will be able to hold. Usually, the character limit is restricted to 136, as it is on Twitter.

After entering the message that you want to hide, offer a password, which the recipient should also know. Once the image is posted, the recipient should press ‘Alt- Control- A’ on the same image. That is when your recipient needs to enter the password and your secret message will be clearly visible to your recipient.

Campbell says, 7,000 downloads of this particular app from his own website has already been registered. The product is an essential part of the research project of Moore. So, have you decided whom you will trust with your secret message and the password to decode it?
