Abstract: Methods and systems for extracting impression marks from a substrate (e.g., paper, foil, textile, etc.). In an example embodiment, an image of a substrate can be captured. Then, physical impressions on the substrate can be detected in the image. The physical impressions are scanned and highlighted a digital image configured, which is indicative of the actual physical impressions. The scanning and highlighting of the physical impressions can involve enhancing the image to digitally and electronically reproduce the physical impressions. This approach can be implemented in the context of a mobile scanning application that scans the physical impression(s) and highlights it, and saves the resulting image as an electronic document.

Abstract: Disclosed herein are methods and systems for adding content in a page of an electronic document without moving current content to a next page of the electronic document. A first electronic document, a position information of a page of the first electronic document where a new content need to be added, and at least one of the new content and a second electronic document including the new content are received at an MFD. A required space for adding the new content and an available space between lines of the page are estimated. The available space and the required space are compared to check whether the available space is more than the required space. Based on the comparison, the lines of the page are re-positioned, and the new content is added on the page based on the position information to generate an updated first electronic document including the added new content.

Abstract: Methods and systems for providing multi-layer reversible data hiding are disclosed. According to the methods and systems, multi-layer reversible data hiding process may be implemented in two stages. The first stage provides embedding of the sensitive data on a secret layer and hiding the secret layer behind single or multiple layers for secure transmission for intended recipient. Subsequently, the second stage is concerned about retrieving or extracting the hidden sensitive data through proper authentication. In the extraction process, the recipient needs to provide the right authentication code for each of embedded layer in order to reach to the secret layer. Upon unsuccessful authentication of any embedded layer, the proposed method enables an intelligent security technique termed as SMART (Suspect Malicious Activity on Rich Tract), which ensures to protect the sensitive data by suspecting the attempts of theft and intrusion.
