This video demonstrates DNAt -- Data and Application tracking, a platform for confidential data processing and tracking of executions of applications over sensitive data in untrusted or open environments. DNAt uses Ethereum smart contracts to build immutable registries of application and data usage. Furthermore, to guarantee confidential execution and enforce that operations are appropriately logged in the blockchain, DNAt uses Intel SGX, a trusted execution environment that protects memory regions even in untrusted environments. Combining these technologies, we foster an ecosystem where data producers and developers of confidential applications can securely share their assets without risking leaking sensitive information or intellectual property.

Relevance for Cloudscape Brazil 2018: 

DNAt leverages recent technologies to enable transparency and confidentiality, fostering innovation and enhancing trustworthiness in cloud environments.
