Social business has improved the ability of managers and stakeholders when decision making. However, existing information security systems provide insufficient practice for information protection while transferring information hackers access valuable information and break encryption codes applied to text messages. This paper presents the development of an Optimized Hybrid Security Model using Base 64 Algorithm and Substitution in Conjunction to enhance message security. This research is a prototype for the user input of message and security key in Hypertext Preprocessor using JQuery. The developed system needs the input of the plain text and the security key. Initially, Base 64 algorithm encrypts plain text into cypher text with the security key and then the Substitution Cipher encrypts the key into a cypher secured key. For testing, 300 text messages were input with different security keys. This research is a step forward in securing text messages it can be used to encrypt text between sender and receiver through email, or it can be applied on instant messaging services and also can be used for stronger password encryption.
