A letter signed by 38 researchers and academics in the fields of computer science, information security and privacy law was sent to Google's CEO. The letter asks Google to uphold privacy promises made to users of Google Cloud Computing services. In March, EPIC filed a complaint with the FTC urging an investigation into Cloud Computing services, such as Google Docs, to determine "the adequacy of the privacy and security safeguards." The EPIC complaint specifically recommended the adoption of encryption to help safeguard privacy and security. Addressing concerns about data vulnerability and interception, the expert group has asked Google to enable HTTPS (web-based encryption) by default in several Google apps, including Gmail.
