Data Security Perspective in Secure Data Communication

Abstract

With the enrichment of use of the internet the confidentiality and security of our information becomes vulnerable now-a-days. Security in confidential information becomes one of the key challenges in context of data leakage and unauthorised access of data. Data security is one of the main concern in recent data industry to prevent alteration and illegal access of data. To ensure utmost security researches are going on rapidly on data security aspects. Various security methods and algorithms has been introduced to protect our data. Data can be secured in multiple forms like converting the actual data into non-readable data by applying cryptography concept, Data can be hidden under any cover medium by applying stenography approaches and visual cryptography. Data can be authenticated through watermarking applications. Thus sensitive information can be protected from unauthorised access. These concepts have been introduced to satisfy main data security principles for ultimate protection.
