Design of new access control structure for provenance based on secret sharing
Access control is one of the important elements in providing confidentiality to the secured data. Access specifiers helps us understand degree of rights given to the users in utilizing data records in a right manner. Tampering the records by unauthorized parties is a high concern in secure communication. Tamper detection plays an important role in trouble shooting an issue associated with network/ host intrusion scenario. The advances in information technology have driven the modern world to focus on the Web for digital information. People across the globe rely on the internet for all the data from generic information to distribution of personal data over heterogeneous networks. Technology has grown so wide to an extent, where almost all of the financial transactions are taking place through online portals. On the other hand, there has been high rise in the security threats towards users confidential data. This information is however shared by the online users while performing financial transaction in e-commerce portals. In order to maintain security mechanism over the untrusted networks various authentication techniques available in this regard. All these security procedures are said to be stubborn and adequate on contextual basis, on the other hand over a period of time the intruders would find out ways to break into systems. Data theft and intrusion into the information systems would increase on a daily basis if defensive measures are not in place. In this concern a new mechanism for securing the data using majority voting concept is proposed. Majority voting for securing the provenance data is applied. Provenance data is data of origin, genesis data and often observed as sensitive data. Provenance is a record of events, timestamps, versions, transformations occurred for the data of interest. Elicitation of an entity's genesis is termed provenance. This understanding is called as data provenance for data objects and their relationships. In most of the cases provenance data is tend to be sensitive, and a small variation or regulation paves way to changes to entire lineage of the connected data. This origin needs to be protected and only approved parties should have right to use the data. Specific description or classification of an instance's historical record or data object is called data provenance. It has many implications in different disciplines in terms of its significance for the acquisition of data flow mechanisms. Personal control of data privacy is a common scenario and various solutions towards security exists. In this regard a unique model is proposed where control of data and its related allies is available with several bodies but however not one; and if access control is to be permitted for a cause based on context, all the entities holding their right keys will have to agree and share on a common platform for accessing the data. Combining these shares in a peculiar pattern allows the grant for accessing data. The method of allocating controls to multiple bodies and allowing grants based on the combination of stakes is called a mechanism for secret sharing. Share separation may be derived from the concept of visual encryption methodology We integrate concepts of secret sharing and provenance to provide an indigenous solution for parameters of information security namely confidentiality, integrity and availability. It is with the availability of exceptional wireless internet access in mobile motivated situations, users and usage data has become massive with respect to media. For example, financial related operations carried out over online platforms by users in many ways were found insecure and unauthenticated. Procedure with appropriate algorithms are available for safe data communication in various modes, however lacks to attain high accuracy and performance with regards to the basic goals of security; confidentiality, integrity, availability at a significant level. Security is the main aspect of any communications among untrusted networks in the current world. Sincere gratitude to many researchers for their tremendous contributions to effective security algorithms despite various threats that compromise the computer systems vulnerabilities. The origin of the data, i.e., by which the transaction thread was created, is the pertinent question to be answered while the financial operation is finalized. This definition of 'data antiquity ' has received good interest from researchers in different fields for many decades and is often termed as data provenance. However, security in provenance has made some progress with recent research, particularly in the field of cyber security. This study emphases on the safety characteristics of data provenance with a distinctive cryptographic approach. The combination of these principles produces unique results for safeguarding the genesis data. -

Synthesis and characterization of heterocyclic derivatives and studies on their photophysical properties
Photophysical properties such as absorption, fluorescence, quantum yields and lifetime of fluorescent heterocyclic compounds have been a subject of extensive research interest. Absorption and fluorescence emission of fluorescent molecules results in electronic transitions between ground and singlet excited state. The bathochromic or hypsochromic spectral shift brings a considerable change in dipole moment of both the electronic states through solute-solvent interactions. We have synthesized some heterocyclic compounds and studied thier photophysical properties. Different derivatives such as Schiff base, chalcone, maleimide and pyranopyrazole were synthesized and characterized by FTIR, 1H NMR, 13C NMR, mass spectrometry and elemental analysis. Photophysical properties of synthesized compounds have been studied through absorption and fluorescence spectroscopy and DFT calculations. We have used solvatochromic approaches such as Bilot-Kawski, LippertMataga, Bakhshiev, Kawski-Chamma-Viallet and Reichardt's solvent polarity parameters to evaluate dipole moments of ground state and singlet excited state of the synthesized heterocyclic compounds. The influence of specific and non-specific interactions on spectral properties was also investigated by using Kamlet-Abboud-Taft and Catalan multiple linear regression equations. X-ray diffraction analysis of hydroxyl Schiff base derivative has been carried out due to the presence of strong inter and intra molecular hydrogen bonding. Solvatochromic analyses of synthesized compounds were done using Bilot-Kawski, Lippert-Mataga, Bakhshiev, Kawski- Chamma-Viallet and Reichardt methods. All Solvatochromic graphs have been plotted for spectral parameters against solvent polarity parameters using Origin 8 software. The obtained experimental results from all methods were compared with theoretical results. The correlation coefficient between microscopic solvent polarity parameter and spectral Stokes-shifts were higher in comparison to bulk solvent polarity functions. Graphs for each molecule provided good correlation based on least square analysis. Dipole moment values of ground and excited states were calculated using slopes of different solvatochromic methods. Higher value of singlet excited state dipole moment indicated that the molecules were more polarised in the singlet excited state. Kamlet-Abboud-Taft and Catalan multiple linear regression (MLR) analyses were used to analyse the solvent effects on absorption, emission and difference in spectral energies of the synthesized molecules. Single point method was used to calculate the quantum yields of the synthesized compounds in ethanol using an ethanolic solution of anthracene as a reference compound. Edwards atomic increment method was applied to calculate the Onsager cavity radii of all the molecules using van der Waals volume. DFT/TD-DFT was used for quantum mechanical calculations of all the molecules. The geometrical structures of the synthesized molecules were optimized using B3LYP/6-311G(d, p) basis set. The positions of HOMO-LUMO orbitals were identified and the band gaps for all the molecules were calculated. Mulliken atomic charges and electrostatic potential surface (MEP) have also been evaluated for all the molecules to identify the ICT pathway and evaluate electrophilic and nucleophilic reactive sites around the molecules . The fluorescence quenching studies of a chalcone derivative by aniline in n-butanol and 1,4-dioxane was performed at 25 ? C which indicated that quenching reactions are diffusion limited. -
