The internet is dead. Over 50% of internet activity is now dominated by bots. Before I visit my own new website there were nearly a thousand visitors already, and tens of daily attacks since. If corporate capitalists owning social media and our taxes don’t get our data with consent, their hackers would without.
I prefer to share my art in the digital world with the utmost protection. Well that’s not quite possible; the solutions like cryptography where you encrypt a message with one key to unlock it, is against sharing, no one else can see it, but it’s obvious there is a secret in there if one cares to decode it. Steganography, however, fundamentally HIDES the SECRET MESSAGE within an innocent-looking cover message. The first documented story of steganography was one of a king who shaved a slaves head, tattooed a secret message on the scalp. After the hair has grown, the messenger is sent off to the destination with a secret shadowed by hair. And the latest story is my Bachelor’s degree thesis on steganography, translated into this app, Terump.

Offline, steganography, secret scrambling with SHA-256, watermarking, metadata modification
COVER IMAGE is the visible image
(input jpg, png,…) you will see some extracted data from your cover image.
SECRET IMAGE is the hidden message
(input jpg, png,…) the hidden message must have the same dimension as the cover image, if it is not the app will automatically resize, keeping proportions.
