The need for publishing maps in secure digital format, especially guarantees data integrity which motivated us to propose a scheme that detects and locates modification data with high accuracy while ensuring exact recovery of the original content. In particular, using fragile watermarking algorithm based on reversible manner to embed hidden data in 2D vector map for each spatial features. In this paper, a reversible data-hiding scheme is explored based on the idea of difference expansion with Manhattan distances. A set of invertible integer mappings is defined to extract Manhattan distances from coordinates and the hidden data are embedded by modifying the differences between the adjacent distances. Experiments results show that the proposed scheme has good performance in term invisibility and tamper modification ability. The scheme could detect modification data such addition and deletion some features, and exactly recovery the original content of the 2D vector map.

In this study, we explored the students' computer-supported collaborative learning behavior based on the Facebook platform. Sixty two senior college students major in Information Management took Decision Support System (DSS) class. Besides the lectures and class discussion, the students participated in the DSS Facebook for collaborative learning. We found that students' characteristics (e.g., gender and mindset of learning) are important factors to affect their Facebook usage behavior and learning performance. The students using DSS Facebook more often get better performance in their final projects, learning satisfaction and the online communication behavior survey. We also found that gender affects the usage of social networks platform. For instance, male students use social networks platform several times per week and get better performance in online communication, learning satisfaction and creativity self-efficacy.
The contribution of this paper is twofold. First, we provide new theoretical insights into the relationship between a string and its reverse: If the Burrows-Wheeler transform (BWT) of a string has been computed by sor...

Development of Electronic Archive Information System was the final step in completing Lithuania's preparation for signed electronic documents. The system is unique not only in Lithuania, but also in Europe. It allows to submit to the state archives the official electronic documents signed by qualified e-signature, assuring their integrity, authenticity, non-repudiation and possibility to use and store them for a long or unlimited time. To resolve the interoperability problems the universal model, sufficient for complex electronic documents during whole of their life cycle has been created and described in two specifications: ADOC - for human readable electronic documents and MDOC - for machine readable electronic documents. The public free software tools for preparation, signing, preview and verification of official electronic documents have played an important role in promoting the usage of electronic documents. The paper presents practical fundamental solutions applied in Lithuania.
Motion segmentation for articulated objects is an important topic of research. Yet such a segmentation should be as free as possible from underlying assumptions so as to fit general scenes and objects. In this paper w...
