Google’s top security staff have raised red flags over plans to open up its search data and Android operating system, warning of potential hacking risks.

The European Commission is set to decide on Google’s interoperability with competitors under the Digital Markets Act. Critics fear this could lead to increased fraud and de-anonymization of user data.

Heather Adkins, Google's vice president for security engineering, warns that if these proposals are implemented, 'we’d see a significant increase in fraud in Europe.' She believes the anonymization methods do not sufficiently protect users' privacy.

The Digital Markets Act categorizes tech giants as 'gatekeepers,' forcing them to share data and systems with competitors. Google argues its proposed anonymization techniques have 'deep weaknesses,' while critics say the plans could benefit smaller companies without compromising security.
