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.

The increased growth in the use of transmission of multimedia medical contents over unsecured and open networks provides insecurity for confidential patient information over these networks. Digital encryption of medical images before transmission and storage is proposed as a way to effectively provide protection of patient information. Encryption before watermarking of these images is necessary in order to ensure inaccessibility of information to unauthorized personnel with patient. This paper presented a visual cryptographic technique for encrypting of medical images before transmission or storage of them. This will make such images inaccessible by unauthorized personnel and also ensures confidentiality. The process made use of an encryption technique that is based on pixel shuffling and a secret key generated from the image.

Hospitals are distributed across geographical areas and it is important for all hospitals to share information as well as integrate their systems for effective researching and health delivery. Health personals and institutions in need of information from hospitals with respect to geographical areas can easily do researches on patients, treatments, disease outbreaks, and effects of drugs. This research work is aimed at integrating of database systems of hospital across geographical areas via a service bus. A centralized service bus was used to facilitate interoperability of applications across platforms and enhance communication within the hospital infrastructure as well as creating enabling environment for new layer of abstractions to be added without modification of the entire system. Concept of Service Oriented Architecture with web services was used for rapid integration solution in solving the challenges faced during integration of multiple incompatible applications.

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 Vigenère ci- pher. At the end, cryptanalysis was performed on the ciphertext. The implementation will be done using java program- ming.

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.
