Context-based Encryption Applied to Data Leakage Prevention Solutions

Data leakage pose a serious threat to companies as the number of leakage incidents and the cost continues to increase. Data Leakage Prevention (DLP) has been studied to solve this information leakage. We propose a DLP solution applying context-based encryption concept, thus sensitive files are encrypted at all time. The cipher key is obtained through the execution of challenges based in the environment context and the company policies. In this paper, we explain the architecture and the design of our DLP system and the proposed challenges.
