Cloud computing is evolving as a firsthand archetype of large-scale distributed computing which adds more power to internet technologies. It is a framework aiming at convenient and on-request network access to an organized and shared pool of resources. Security of data transmitted and stored by a third party happens to be the greatest challenge for organizations embracing the technology. In this work, a proposed hybrid algorithm dubbed the Soldier Ant Algorithm (SAA) a blend of the Diffie-Hellman algorithm and Delta Encoding technique (Newton Forward and Backward Interpolation). The motivation obtained is the integration of algorithms for cryptography purposes. The integration makes the proposed SAA algorithm symmetric and also makes the Diffie-Hellman algorithm withstand security threats such as man-in-the-middle attacks. The proposed algorithm establishes a secured connection between the cloud client and the cloud service provider and at the same time secures the data sent to the cloud. A comparative analysis was performed against RSA and ElGamal and indicated that the proposed algorithms’ encryption and decryption time were lower even though it is linear (O(n)).

Objective: The objective of the study was to assess the current success rate of hypertensive patients in achieving blood pressure (BP) treatment goals and to investigate the extent of the consistency in the control of BP following initial achievement. Methods: At the hypertension clinic of the B/A Regional Hospital in Sunyani, Ghana, the current BP of 400 sampled patients, aged 35–100 years was measured. In addition, a retrospective review of nine successive BPs previously recorded in patients’ medical histories was done. Results: Of the 400 patients, women constituted 71.75%. Hypertensive aged ≥60 years represented 64.25% with the rest being ˂60 years. In 58% of patients, there were comorbidities. The adherence to clinic appointment was 54.50%. Of the ten clinic visits, 20.30% of patients ˂60 years were adequately controlled of their BPs while those ≥60 years achieved 33.80% control. In all, 29% of the 400 hypertensives met their treatment goals adequately. Consistency in maintaining a controlled BP at all times was achieved by 23.70% of the 400 patients. Regular visits to clinic was associated with adequate BP control (p˂0.001) while comorbidity was not (p=0.122). Conclusion: Treatment goals’ achievement by hypertensives at the Regional Hospital in Sunyani, Ghana, was relatively low. Consistency in maintaining a controlled BP while on medication is poor. The lack of consistency in keeping a controlled BP may contribute to the increased cardiovascular deaths among hypertensives. Intensive mass education and treatment optimization are required to deal with treatment failures among patients.
