    Securing patient data in the cloud using Attribute Based Encryption
    (International Journal of Scientific & Engineering Research, 2015-03-01) Subburaj, R; Hwata, C; Jekese, G
    Cloud computing has attracted attention worldwide in all industries, including the medical field leading to the rise of electronic healthcare systems. Although it has brought about an improvement in the provision of healthcare in terms of information management, it also poses a lot of security and privacy concerns to the patients. This is due to the fact that personal and highly sensitive data is outsourced to a third party (Cloud Service Provider) for processing and storage. This paper seeks to improve security of cloud-based patient data in healthcare organizations by employing a Ciphertext Policy Attribute Based Encryption (CP-ABE) scheme. The proposed scheme provides data confidentiality and allows the patient to control who accesses her personal health data by encrypting it under a specified access policy alongside with her key. It also provides collusion-resistance, flexible and immediate revocation of users who are no longer allowed to access a patient’s data.

    Impact of Object Oriented Design Patterns on Software Development
    (International Journal of Scientific & Engineering Research, 2015-02-02) Subburaj, R.; Jekese, G; Hwata, C
    —Software design patterns are a bonanza for building large Object Oriented (OO) software systems. They provide well-tested and proven solutions to recurring problems that developers address. There are several benefits of using patterns. They can speed up the software development process. Design patterns consolidate learning with an aim to make it easier for designers to use well-known and successful designs developed from expert experience. At the same time software design patterns are too abstract and remain an art that has to be mastered over time with experience. This paper seeks to evaluate the advantages and disadvantages of design patterns.
