Proposed Tiktok Solution Would Have Oracle Provide Data Security

One of the deals being considered to keep TikTok operating in the U.S. reportedly involves Oracle taking a small stake in the company and working with U.S. buyers to ensure that no user data would be accessible to the Chinese government. That is one of the proposals being considered as the April 5 deadline for a deal approaches, Bloomberg reported Tuesday (March 18). The proposal would leave TikTok’s algorithms in Chinese hands while ensuring that a new U.S. version of the app would not have a back door that could be exploited by the Chinese government, according to the report
