A cryptographic image encryption technique for facial-blurring of images

Protection of faces in pictures and videos of people in connection with sensitive information, activism, abused cases and others on public broadcasting media and social net- works is very important. On social networks like YouTube,facebook, Twitter and others, videos are being posted with blurring techniques of which some of them cannot be recoverable. Most blurring techniques used can easily be recoverable using off-the-shelf software. The ones that are difficult to be recovered also can easily be used by abusers and ther wrong doers. This paper proposes an image encryption technique that will make it possible for selected facial area to be encrypted based on RGB pixel shuffling of an m*n size image. This will make it difficult for off-the-shelf software to restore the ncrypted image and also make it easy for the law enforcement agencies to reconstruct the face back in case the picture or video is related to an abuse case. The implementation of the encryption method will be done using MATLAB. At the and, there will be no change in the total size of the image during encryption and decryption process.Comment: 7 pages.

A Hybrid Cryptosystem Based On Vigenere Cipher and Columnar Transposition Cipher

Privacy is one of the key issues addressed by information Security. Through cryptographic encryption methods, one can prevent a third party from understanding transmitted raw data over unsecured channel during signal transmission. The cryptographic methods for enhancing the security of digital contents have gained high significance in the current era. Breach of security and misuse of confidential information that has been intercepted by unauthorized parties are key problems that information security tries to solve. This paper sets out to contribute to the general body of knowledge in the area of classical cryptography by develop- ing a new hybrid way of encryption of plaintext. The cryptosystem performs its encryption by encrypting the plaintext using columnar transposition cipher and further using the ciphertext to encrypt the plaintext again using Vigen\`ere ci- pher. At the end, cryptanalysis was performed on the ciphertext. The implementation will be done using java program- ming.Comment: 7 pages.

Criminal Geographical Profiling: Using FCA for Visualization and Analysis of Crime Data

Fighting criminal activities in our modern societies required the engagement of intelligent information systems that can analyze crime data geographically and enable new concepts to be deduced from it. These information systems should be able to create visualization of such data as well as have the capability of giving new incite of information, if data is updated whilst maintaining the previously predicted patterns. This paper proposed the use of Formal Concept Analysis, or Galois Lattices, a data analysis technique grounded on Lattice Theory and Propositional Calculus, for the visualization and analysis of crime data. This method considered the set of common and distinct attributes of crimes in such a way that categorization are done based on related crime types, geographical locations and the persons involved.Comment: Submitted to International Journal of Research in Engineering & Advanced Technology (IJREAT).pp: 1-5.1.5.(2013). arXiv admin note: substantial text overlap with arXiv:1307.8112, arXiv:1307.778

Visualization and Analysis of Geographical Crime Patterns Using Formal Concept Analysis

There are challenges faced in today's world in terms of crime analysis when it comes to graphical visualization of crime patterns. Geographical representation of crime scenes and crime types become very important in gathering intelligence about crimes. This provides a very dynamic and easy way of monitoring criminal activities and analyzing them as well as producing effective countermeasures and preventive measures in solving them. But we need effective computer tools and intelligent systems that are automated to analyze and interpret criminal data in real time effectively and efficiently. These current computer systems should have the capability of providing intelligence from raw data and creating a visual graph which will make it easy for new concepts to be built and generated from crime data in order to solve, understand and analyze crime patterns easily. This paper proposes a new method of visualizing and analyzing crime patterns based on geographical crime data by using Formal Concept Analysis, or Galois Lattices, a data analysis technique grounded on Lattice Theory and Propositional Calculus. This method considered the set of common and distinct attributes of crimes in such a way that categorization are done based on related crime types. This will help in building a more defined and conceptual systems for analysis of geographical crime data that can easily be visualized and intelligently analyzed by computer systems.Comment: 6 pages.

Using SOA with Web Services for effective data integration of Enterprise Pharmaceutical Information Systems

Medicines exist for combating illnesses and drug stores provide an outlet for consumers to gain access to these drugs. However, due to various factors such as cost of production, accessibility and legal issues as well as distribution factors, availability of these drugs at any location cannot be guaranteed at all times. There is need for individuals and organizations such as hospitals to be able to locate required drugs within given geographical vicinity. This is of immense importance especially during emergencies, travel, and in cases where the drugs are uncommon. This research work is aimed at solving this problem by designing a system that integrates all drugstores. The integration of the drug stores will be based on SOA concepts with web services via a central service bus. The database systems of the drug stores will be integrated via a service bus such that drugs can easily be searched for and the results will be displayed based on its availability. Drugs can easily be searched for within geographically distributed pharmaceutical databases as well as consumption of drugs with relation to geographical locations can easily be monitored and tracked. This will make it easy for health institutions to research on drug consumption patterns across geographical areas and also control their usage.Comment: 11 pages paper.
