IoT-based real time signature authentication and transfer from document to document with DNA encryption

The main idea of this paper is to suggest a way in which, by using the Internet of Things (IoT), a person can sign a document in a particular place, and have it reflect simultaneously on a similar document elsewhere, in real time. The primary user (authenticator) uses a digital pen to sign the paper document. The signature area of the document contains a particular dot pattern which helps the digital pen track the movements as the signature is created. While the paper is being signed, the digital pen also records the user's fingerprint for later verification. The obtained information is then converted to binary bits and is encoded using DNA encryption. This cipher data is transmitted to the secondary user (receiver) where the cipher is decoded and printed on the second copy of the document. Thus, the signature is securely transferred from one paper to the other.
