TREE AUTOMATA BASED ON COMPLETE RESIDUATED LATTICE-VALUED LOGIC: REDUCTION ALGORITHM AND DECISION PROBLEMS

In this paper, at first we define the concepts of response function and accessible states of a complete residuated lattice-valued (for simplicity we write $mathcal{L}$-valued) tree automaton with a threshold $c.$ Then, related to these concepts, we prove some lemmas and theorems that are applied in considering some decision problems such as finiteness-value and emptiness-value of recognizable t...

Hiding Sensitive Fuzzy Association Rules Using Weighted Item Grouping and Rank Based Correlated Rule Hiding Algorithm

Extracting knowledge from large amount of data while preserving the sensitive information is an important issue in data mining. Providing security to sensitive data against unauthorized access has been a long term goal for the database security research community. Almost all the research in privacy preservation is limited to binary dataset. Business and scientific data contain both quantitative...

A Text Information Hiding Algorithm Based on Alternatives

In this paper, we analyze existing text-based steganography techniques, and propose an efficient information hiding algorithm for text based on substituted conception. In this algorithm, candidate units are replaced by similar conception, including synonym, homonym or special character. An improved encoding algorithm is also proposed which is not only enhances the robustness, but also enlarges ...
