Health-chat App: Secured Patient’s Health Information App-based (SPHIA) using Integrated Data Encryption Algorithm (IDEA)

Abstract

The era of the digital landscape had caused evident progress, unfortunately this also became an avenue for untoward activities such as data breach, data manipulation, hacking and others. The Philippine Government had already enacted and promulgated numerous Laws that protects the rights of every individual, and one of this is the Data Privacy Act of 2012. This act protects the health data and is considered as sensitive personal information that penalizes Institution in the event of leakage of such information.

To resolve this pressing concern, the Health-chat App Mobile application was developed to safeguard patient’s health information. The Integrated Data Encryption Algorithm (IDEA) is the merging of two strong algorithms, the Data Encryption Standard (DES) and Blowfish algorithm to protect sensitive information on health. The IDEA displays strength on its security with the calculated avalanche effect of 52.41% as compared when the original algorithm was used.

Based on the result, the application is a new platform that can be used to safeguard health sensitive information that protect and uphold the individual’s right to privacy.
